Pathfinder Award Development of new leads for animal trypanosomiasis This programme builds on a DFID funded drug discovery and development collaboration between the University of Dundee’s Drug Discovery Unit and the Global Alliance for Livestock Veterinary Medicines (GALVmed) to continue medicinal chemistry optimisation and development of a novel lead compound series as a veterinary drug for the treatment of Animal African Trypanosomiasis in cattle.

The aim is to deliver a new treatment for this parasitic disease which is spread predominantly by tsetse flies in sub-Saharan Africa. It causes serious economic losses in in important livestock including cattle, goats and camels as a result of reduced productivity from clinical disease with severe anaemia, emaciation and mortality. Of particular importance is the reduction in draught power or traction of infected animals which leads to a corresponding reduction in the ability to prepare (plough) fertile land for production of important crops. In the >10 million km2 of fertile land across 40 African countries infested with tsetse flies, which are inhabited by >56 million cattle and >70 million small ruminants, more than 3 million cattle die annually of the disease. This is despite the use of more than 150 million annual doses of existing commercially available animal drug treatments (trypanocides).These currently used trypanocides (including diminazene and isometamidium) were discovered more than 50 years ago and have limitations with respect to toxicity, safety and increased emergence of drug resistance. No vaccines against the disease are available nor likely to be developed in the near future due to immune evasion via antigenic variation with trypanosomes. There is therefore a clear and urgent need for novel pharmaceutical livestock products for the treatment and prophylaxis of Animal African Trypanosomiasis.

Pathfinder Award Use of secretion inhibitors as novel antifungal drugs Meningitis due to the fungal pathogen Cryptococcus neoformans is rampant in Africa. Nearly one Meningitis third of patients have shown treatment failure or resistance to currently available antifungals, demonstrating a tremendous need for the identification and development of new drugs to combat this fungal infection

A Pathfinder Award to Prof. Marcio L. Rodrigues (Centre for Technological Development in Health, Fiocruz, Brazil), in partnership with the Institute of Pharmaceutical Technology of Farmanguinhos will provide pilot funding for the search of antifungals with the ability to inhibit the cellular traffic of key virulence factors used by C. neoformans to cause damage to host cells.

Translation Award Phase I trial: t4 immunotherapy of squamous cell carcinoma of head and neck (SCCHN)
Head and neck cancer causes over 2,800 deaths in the UK each year. Unlike many other cancers, the primary cause of morbidity and mortality is locally advanced disease, rather than metastasis.

To address this, Dr John Maher from King’ s College London has received a Translation Award to test a novel treatment called T4 immunotherapy. T4 immunotherapy is a novel cell therapy in which patient immune cells (T-cells) are modified using a safe virus to express two new fusion proteins and are then expanded in culture  for 2 weeks.  The first fusion protein is a chimeric antigen receptor (CAR) that enables T-cells to recognize and kill tumour cells that express any of a range of ErbB receptor pairs. The second fusion protein facilitates the expansion process, rendering manufacture of cell products more robust. To maximise effectiveness and minimise risk, T4 immunotherapy will be injected directly into the tumour at a single setting, under ultrasound guidance. The primary focus of the study is the assessment of safety of this approach but several secondary objectives will also be investigated, including a preliminary assessment of effectiveness.

Seeding Drug Discovery Structure-aided discovery of CaMK1D kinase inhibitors as targeted therapeutic agents for breast
cancer
Kinases are important targets for blocking cancer progression.  However, many remain to be exploited.  For example, no drugs are yet available to specifically inhibit any kinase which is switched on by a regulatory protein called calmodulin. Nonetheless, faulty expression of these “CaMK” enzymes is now thought to play a key role in breast cancer progression.

The Wellcome Trust has funded the CAMSEED consortium to discover small molecule inhibitors for a CaMK protein involved in basal-like breast cancer.  The three dimensional structure of this target has been solved by the Structural Genomics Consortium and Professor Stefan Knapp at the University of Oxford.  Interactions with small molecules are being screened by Professor Michael Overduin’s lab at the University of Birmingham using superconducting magnets and high throughput robots at the national HWB-NMR facility.  The design of improved inhibitors that can enter cells and selectively block the oncogenic state is being led by Professor Peter Fischer at the University of Nottingham, with Colin Kenyon at CSIR, Pretoria designing deuterated analogs for enhanced activity.  The result of the two year project is expected to be a set of lead molecules for development as potential therapeutic agents for breast cancer, and may yield a new approach for using nature’s own inhibitory mechanisms to block cancer-causing kinases.
Salmonella Typhimurium
Translation Award Bispecific small molecule antibody conjugate for hormone-refractory recurrent prostate
cancer
The Wellcome Trust has funded a research team at the California Institute for Biomedical Research (Calibr) lead by Dr Chanhyuk Kim to develop a novel immunotherapy to treat prostate cancer. Prostate cancer is the second most common cancer in men and kills 250,000 men per year worldwide. 

There is currently no effective treatment for prostate cancer which has progressed to hormone-refractory prostate cancer (HRPC).  Patients with HRPC on average only live 1-2 years before succumbing to the disease.  In a search for new treatments, the team at Calibr have created a drug that engages the patient’s immune system to seek and destroy prostate tumor cells. This technique is a promising alternative to chemotherapy.  The properties of this novel protein conjugate enable it to efficiently target malignant HRPC cells and recruit a robust anti-tumor immune response.  Preclinical research demonstrates that this therapy effectively eliminates tumor cells both in vitro and in mouse models.  The primary goal of the proposed research is to develop this technology through safety studies and initiate pilot scale manufacturing.  This will enable preparation of an investigational new drug application and serve as a catalyst for an industry partnership to carry out a Phase I clinical trial, thereby offering this innovative new therapy to patients with HRPC.

Seeding Drug Discovery Design and development of AMPA receptor modulators with a much improved safety profile as novel drugs for treating the cognitive dysfunction associated with schizophrenia and other CNS disorders Around 1% of the population will suffer from schizophrenia at some point in their life. Symptoms such as paranoia and/or hearing voices can be reasonably well treated by existing medications. However, these drugs have little effect on the other symptoms (lack of motivation and impaired social function) and impaired cognition, including difficulties with attention, memory and problem-solving that result in a “brain fog”.


These largely untreated symptoms remain a huge barrier to the resumption of a fully functional, “normal” life for these individuals and are associated with an annual estimated cost in the UK alone of around £12 billion.  Professor Simon Ward from the University of Sussex has received a Seeding Drug Discovery Award to identify and develop drug which is a selective modulator of the AMPA receptor which has the potential to provide an innovative new treatment for patients with schizophrenia. If successful the team expect to have a compound ready for clinical evaluation in just over three years time.  Nerve cells (neurons) communicate with each other by releasing chemicals known as neurotransmitters that interact with proteins called receptors on adjacent neurons. Levels of the neurotransmitter glutamate,  which is crucial for normal cognitive function, are altered in schizophrenia. A specific subtype of glutamate receptor, the AMPA receptor, is thought to be associated with cognition and therefore increasing AMPA receptor function should improve cognitive performance in schizophrenia and thereby addressing an unmet need and revolutionizing the functional outcome of this patient population.
Retinoic acid receptor a agonists for the treatment of Alzheimer's disease
Translation Award A systematic programme to develop and evaluate the best candidate treatments for repositioning as therapies for Alzheimer’s Disease (SMART-AD)
This innovative programme will identify drug candidates for repositioning in Alzheimer’s Disease (AD).  Professor Clive Ballard and colleagues at King's College London, will compare the transcriptional signature of AD with the signatures of up to 4000 drugs with established safety in man to identify 100 candidates with the most promising therapeutic potential.

State of the art gene profiling will be used to determine the ability of the candidates to modify the expression of disease-associated transcripts in hippocampal neurons, with the best 20 drugs going forward to test for biological efficacy in in-vitro assays for a wide-range of pathogenic mechanisms implicated in AD. The six agents with the most favourable impact will then be evaluated in the best rodent model of AD to obtain the proof-of-principle evidence that would support a clinical program. Importantly assays used will measure a range of key pathological and behavioural outcomes, as well as determining the drugs impact on disease-associated transcriptional changes. Each stage will be overseen by an independent expert panel to ensure drug selection is rigorous and appropriate for AD. The overall aim of this programme of research is to identify the best candidate to be taken forward to clinical trial in people with AD.
Salmonella Typhimurium
Pathfinder Award Better drugs for cryptosporidiosis: hit-to-lead studies for confirmed MMV screening Cryptosporidium parasites are intracellular and related to malaria parasites, but the infection is restricted to the intestinal epithelium.

This award is to fund the collaboration between the University of Vermont and Medicines for Malaria Venture (MMV) to determine if assets from the MMV Malaria Box have the pharmacologic characteristics required for a potential effective anti Cryptosporidium  drug that differs from those needed to treat systemic infections.

Seeding Drug Discovery Apolipoprotein E4 as a therapeutic target for Alzheimer's disease:  Identification of small molecule structure correctors to prevent apolipoprotein E4-associated neuropathology Apolipoprotein E4 (apoE4) is the major genetic risk factor for Alzheimer's disease (AD). Indeed, one in four people carry the apoE4 gene, whereas 65 to 80% of all AD patients have at least one copy of apoE4.

The apoE protein, which functions in the normal maintenance and repair of nerve cells, occurs in two major forms: apoE3 and apoE4. ApoE3 is often referred to as the normal form, while apoE4 differs from apoE3 by the change of a single amino acid residue (1 out of 299). This single change causes apoE4 to have an abnormal structure and function. As a result of this abnormal structure, the production of apoE4 in nerve cells sets off a chain of events that, over time, leads to neuronal degeneration and cell death. Believed to be an intruder, apoE4 is attacked by a protease enzyme and cut into smaller toxic fragments. These fragments then wreak havoc on many vital structures in the cells.  Robert W Mahley, MD, PhD, and his colleague Yadong Huang, MD, PhD, have identified small molecules that correct the abnormal structure of apoE4, mitigating its harmful effects by converting it to the functionally normal apoE3. The Trust has awarded $2.5 million over two years to Dr Mahley and the Gladstone Institutes to develop new chemical entities that target apoE4 in the brain in order to prevent the development of AD. Under the award, Gladstone will collaborate with San Francisco-based chemoinformatics company Numerate for chemistry expertise.

Pathfinder Award Development of human induced pluripotent stem cells (iPSCs) in patients with neurodegeneration with brain iron accumulation (NBIA) A Pathfinder Award to Dr Michael Hutton at Eli Lilly, in partnership with Professor John Hardy at UCL, will provide pilot funding for this Industriy-Academic partnership to work on the rare disorders termed Neurodegeneration with brain iron accumulation (NBIA).

This is a group of rare, severe neurological disorders that are characterised by parkinsonism, cognitive decline and dystonia.  The Award will fund the development of human induced pluripotent stem cells (iPSCs) cells offers a way to develop in vitro models of these diseases in the laboratory, without exact knowledge of the disease mechanism(s). The cell characteristics will enable these models to be amenable to drug treatment from the array of therapeutic compounds held by Lilly going forward.

Pathfinder Award Developing a transformative therapy for inherited homocystinuria by correcting the misfolding of cystathionine beta synthase disease alleles This Pathfinder Award brings together world-class researchers from Pfizer Inc.’s Rare Disease Research Unit in Cambridge, MA (US), including Dr Christine Bulawa of Pfizer, and the Structural Genomics Consortium (SGC) in Oxford (UK), including Dr Wyatt Yue, to study cystathionine beta synthase (CBS) deficiency.  CBS deficiency is a rare genetic disorder in which affected people cannot process the amino acid methionine.

In many patients, a genetic defect causes the CBS enzyme to lose its optimal three-dimensional shape and prevents the enzyme from functioning properly.  This leads to the build up of homocysteine in the body, causing an array of symptoms including early cardiovascular disease. The current standard of care is to reduce homocysteine levels by a methionine-restricted diet or supplementation with vitamin B6, a cofactor for the CBS enzyme. However, this does not treat the underlying cause of the disease, and many patients do not respond to these treatments.   During the course of this collaborative research, scientists at Pfizer and SGC aim to develop biochemical and molecular tools to facilitate discovery of a potential drug that restores the optimal shape and function to the defective CBS protein, thereby treating the root cause of the disease.

Pathfinder Award A preclinical feasibility study using recombinant homogentisic acid dehydrogenase as an enzyme replacement therapy for alkaptonuria There are over 6000 known rare diseases and most are of genetic origin. One such condition is alkaptonuria (AKU), which is caused by a faulty enzyme.  This means patients produce a chemical called homogentisic acid (HGA). Some HGA leaves the body in urine. The rest builds up in body tissues, eventually causing serious health problems.

Some of this HGA is converted into a black pigment. Over time this black pigment stains joint tissues, including bone and cartilage, causing early onset, severe arthritis. This is why AKU is also known as ‘black bone disease’. Patients also suffer severe pain and heart disease. Most AKU patients become severely disabled as life progresses and many of them end up wheelchair-bound. There is no known cure for AKU and current treatment relies on pain management and joint replacement. This project's key objective is to test the idea of enzyme replacement therapy (ERT). We will make human enzyme in bacteria (as a method of manufacture) and then test it in mice with AKU. If this reduces the effects of AKU in the mice, then it might be possible to treat this debilitating disease for the first time.  This is a collaboration between Protein Technologies Ltd and the University of Liverpool.

Seeding Drug Discovery Fragment-based lead discovery against the protein-protein interaction between Aurora A and TPX2 for the treatment of cancer The Wellcome Trust has awarded over £2.3 million to Chris Abell, John Skidmore and co-workers at the University of Cambridge to use fragment-based approaches for the generation of molecules which disrupt the interaction between the kinase Aurora A and the regulatory protein TPX2.

Such compounds are expected to have utility in the treatment of a number of solid and haematological cancers, with one particular focus being reversal of taxane resistance in solid tumours. The project will generate lead compounds suitable for screening in cancer cell-lines and animal models to further validate the target and will also provide leads for future optimisation towards a drug. This funding follows on directly from an ongoing Strategic Award pioneering the use of fragment-based approaches against protein-protein interactions, which used biophysical screening and X-ray crystallography to generate the fragment leads for the planned project.

Translation Award Treatment of obesity with the pancreatic polypeptide analogue PP 1420 Obesity is a massive health problem worldwide. Currently, no medication is safe and effective. Imperial College have developed a new drug for obesity called PP 1420, which uses the body’s natural satiety system for controlling appetite.

It is given as an injection once a day and works by suppressing appetite. In a previous study, Imperial tested PP 1420 for the first time in healthy volunteers, and found that it was both safe and without side effects. The Wellcome Trust are now supporting a further study of PP 1420 to show that PP 1420 is able to reduce food intake and body weight when multiple doses are given.  This study if headed up by Professor Sir Stephen Bloom
Seeding Drug Discovery A stream-lined lead optimization project with the potential to deliver first in class small molecule inhibitors of Respiratory Syncitial Virus (RSV) RSV is one of the most important respiratory pathogen with 64 million infections and 160,000 deaths estimated worldwide annually. RSV infection is responsible for more infant hospitalizations than other viral infections such as influenza.

Susceptible populations are premature infants, children, transplant patients, the elderly and people of all ages with heart failure and lung disease. In addition, severe infection in infancy is linked to the later development of asthma. In the elderly in the US it was shown that RSV infection caused 177,500 hospital admissions and 14,000 deaths over a period of 4 years.  Hospitalization costs alone were estimated at more than $1 billion.  re:VIRAL Ltd is focused on development of novel antiviral treatments for RSV.  The Company has been granted an Seeding Drug Discovery award from the Wellcome Trust to develop novel small molecule RSV fusion inhibitors up to completion of  preclinical studies.  This project is a collaboration between re:VIRAL Ltd. and the University of Sussex Drug Discovery group. The key goals of this project are to identify a drug candidate suitable for progression into studies in man and novel back compounds with the ambition of developing the first approved therapy for RSV.
Translation Award Development of novel small molecules for the treatment of antibiotic resistant bacterial infections Due to a dearth of new antibiotics in development, resistant bacteria are presenting a growing challenge to patients, physicians, and health organizations, resulting in higher patient morbidity and mortality as well as increased health system costs.

For example, the alarming spread of newly emerging “CRE” (Carbapenem-Resistant Enterobacteriaceae) “super-bugs” threatens to become a global crisis.   With an investment of $8.9M from the Wellcome Trust Translation Fund, VenatoRx is developing new antibacterial therapeutic products to address multi-drug resistant gram negative bacteria, including resistant E. coli, K. pneumoniae, and P. aeruginosa, important causative agents for complicated urinary tract infections, complicated intra-abdominal infections and many types of serious pneumonia.

Seeding Drug Discovery Next Generation Broad-Spectrum Antifungal Treatment – Development of a Fungal Proton Pump Inhibitor Drug Candidate Fungal infection is a serious problem, especially for critically ill patients. There is an increase in the number of infections that cannot be treated with the medicines available today. This is in part caused by the increased number of infections with fungi that are resistant to existing drugs but also due to the appearance of treatment resistant rare types of fungus and the increased use of immunosuppressants to treat cancer and transplant patients.

The Wellcome Trust has funded Pcovery to develop a new drug with a novel mechanism of action for the treatment of serious fungal infections. The project will target a specific protein that is distinct for fungal cells, essential for fungal survival, and highly conserved across a number of fungal species. The hope is to identify a drug like compound, which will inhibit the function of the target protein and kill off the fungi without affecting the patient. Due to this novel mechanism of action it is expected that the drug will be active against fungi that are resistant to other antifungal drugs. It is also anticipated that the drug will have few side effects.

Seeding Drug Discovery Development of compounds that inhibit RAS-effector protein-protein interactions in cancer using a single antibody domain drug surrogate emulator approach Prof Rabbitts and colleagues from the Weatherall Institute of Molecular Biology have been awarded Seeding Drug Discovery funding to develop small molecules specifically targeting the RAS-effector protein-protein interactions.

The RAS family of oncogenes is among the most frequently mutated in human cancers. Using minimal antibody fragments, the group has characterized an anti-RAS VH segment whose binding site covers the region of RAS where the signal transduction effector proteins bind, the “switch region.” In models of lung cancer this anti-RAS VH inhibits tumourigenesis, thus validating the mutant RAS-effector interaction as a therapeutic target. Using two different approaches small molecules have been identified that bind to RAS at the same point of contact as the anti-RAS VH. The Seeding Drug Discovery  Award will be used to develop these hits through to leads and ultimately the identification of a preclinical development candidate.

Seeding Drug Discovery Design and Optimisation of New Chemical Entities that Prevent the Neurotoxic Oligomerization and Misfolding of both β-amyloid and tau Proteins: A Disease Modifying Therapeutics Approach for Alzheimer’s Dementia Wellcome Trust has awarded a grant to TREVENTIS Corporation to discover a disease-modifying drug for the treatment of Alzheimer's disease (AD). Numerous studies support the causative role of β-amyloid (Aβ) and tau in the aetiopathogenesis of AD.

These proteins tend to abnormally "clump" (protein misfolding) and give rise to neurotoxic aggregates of β-amyloid (plaques) and tau ("tangles"), the pathological hallmarks of AD. In vitro studies have identified that Aβ can be neurotoxic when in small aggregates. Since disease-modifying drugs represent the most desirable therapeutic approach to AD, protein misfolding of Aβ and tau represents a potential target in the rational design of a drug. The ultimate goal of this research is to discover a disease-modifying new chemical entity for the treatment of AD that is efficacious and safe. This goal will be achieved by optimizing a class of small organic molecules capable of binding to both β-amyloid and tau, blocking their misfolding. A new series has recently been identified that are drug-like, potent anti-aggregants and penetrate the Central Nervous System. Funding under this award will enable the discovery of a lead candidate with completed pre-clinical pharmacokinetic and toxicology package.
Seeding Drug Discovery Inhibition of small-conductance Ca2+-activated potassium (SK) channel as a novel concept for the treatment of atrial fibrillation Atrial fibrillation (AF) is the most common cardiac arrhythmia (irregular heart beat), affecting an estimated 4.5 million people in the EU. AF mainly affects the elderly population and lifetime risk for developing AF is 25% for individuals over 40 years of age.

AF is associated with impaired quality of life, increased rate of hospitalisation, and increased risk of stroke and death.  The Wellcome Trust has funded the Danish Biotech company Acesion Pharma to develop a novel pharmacological treatment for the acute cardioversion of AF to normal heart rhythm (sinus rhythm). The project aims to identify a compound that selectively blocks the so-called SK channel, a novel biological target for AF treatment.

Currently used medicines against AF are only moderately effective in cardioversion and have risk of serious adverse effects. There is therefore a significant medical need of new treatment options with better safety profile and higher efficacy. Based on Acesion Pharma’s existing know-how on SK channels and compounds blocking this ion channel, it is envisaged that such a compound could become a safer and more efficacious drug for AF.
Seeding Drug Discovery GSK Diseases of the Developing World Discovery Engine GSK's Tres Cantos Medicines Development Campus in Madrid, Spain has received a commitment from the Wellcome Trust to provide up to £5m in support of its open approach to discovering and developing urgently needed new treatments for diseases of the developing world.

The funding will move early-stage research to the next level, to find new medicines for diseases such as TB, malaria, Leishmaniasis and sleeping sickness. Scientists from around the world will work in collaboration with GSK drug discovery experts at its facility in Tres Cantos, Madrid which also houses GKS's Open Lab. The funding will provide the opportunity to progress the most promising projects underway by independent scientists at the Open Lab and from GSK's own research portfolio. The overarching goal of the investment is to develop two high-quality experimental drugs over the next five years.
Strategic Translation Award Administration of sNN0029 (VEGF) using an implanted drug delivery system for the treatment of patients with Amyotrophic Lateral Sclerosis Amyotrophic Lateral Sclerosis (ALS)  is a deadly disease that causes death of nerve cells (motor neurons) that are normally used to control breathing, swallowing and movements, e.g. of limbs. The disease affects 200,000–300,000 patients worldwide and approximately 90% of patients with ALS die within 5 years of diagnosis.

sNN0029 is a drug that contains a naturally occurring protein called VEGF that has been shown to have disturbed expression in the central nervous system of ALS patients, as well as promoting survival of motor neurons in relevant rodent models.  Based on these findings, NeuroNova AB – a Swedish subsidiary of Newron Pharmaceuticals in Milan, Italy – has developed a therapy to directly deliver VEGF into the brain using a drug delivery system which is placed underneath the skin. The company has completed a three month phase I/II safety and tolerability study of this therapy in ALS patients. The Wellcome Trust is now providing a programme-related investment to complete a phase I/II trial to evaluate safety and efficacy of higher doses of sNN0029 in patients with ALS.
Seeding Drug Discovery A Centre of Excellence for lead optimisation for diseases of the developing world There is an urgent need for new drugs to treat the major infectious diseases of the developing world, such as TB, malaria and African sleeping sickness. However, despite significant efforts in early stage drug discovery, there is a bottleneck when it comes to the lead optimisation stage of molecules targeting these diseases.

To address this need Professor Paul Wyatt and colleagues at the Drug Discovery Unit (DDU) at the University of Dundee, with joint funding from the Wellcome Trust and Bill & Melinda Gates Foundation, are establishing “A Centre of Excellence for Lead Optimisation for Diseases of the Developing World.” The initial focus will be on TB, where the strategy is to identify a portfolio of TB Lead Optimisation projects through the DDU’s involvement with the HIT-TB consortium and TB Drug Accelerator Program which are working to generate leads through their screening programmes. The DDU as part of HIT-TB is already identifying and optimising multiple hit series that could be taken up by the team.
Seeding Drug Discovery Novel small molecule inhibitors of metallo ß-lactamases for the treatment of multi-drug resistant Gram-negative infections Multi-drug resistant Gram-negative bacteria account for most hospital infection worldwide (e.g.  causing 25,000 deaths in Europe and extra healthcare costs/productivity losses of >€ 1.5 billion/year).

One of the most effective treatments is the use of carbapenem antibiotics. However, their usefulness is becoming increasingly compromised due to the rise of clinical resistance associated with the spread of genes encoding various metallo ß-lactamase (MBL) enzymes, primarily the carbapenemases NDM-1, VIM-1/VIM-2 and IMP-1.

The Trust has awarded Dr. Marc Lemonnier, CEO of Antabio, €4.7m over 3 years to fund the development of a novel, safe and efficacious pan-inhibitor of bacterial metallo ß-lactamases. The project team being led by Principal Investigator Dr. Marc Lemonnier, will develop drugs inhibiting these MBL enzymes, thereby returning carbapenems to full clinical effectiveness. The project will develop current leads to preclinical candidate nomination. It is envisaged that hospitalised patients suffering from complicated Gram-negative infections will be treated with a combination of Antabio’s new inhibitor coadministered with a carbapenem.

This therapeutic concept has been successfully proven by existing beta-lactam/ serine beta-lactamase inhibitor combinations such as Augmentin (Amoxycillin/Clavulanic acid). Since these combinations will not work against bacteria that are MBL producers, the medical need for MBL inhibitors remains critical. A beneficial feature of this paradigm is that oral activity is not required – carbapenems are taken intravenously, so a newly developed inhibitor can be coadministered through that route. This regimen simplifies the research and greatly increases the possibilities for success. A successful drug will alleviate patient suffering and reduce antibiotic failure in the clinic.

Translation Award First in Human clinical trials for SMT19969: A novel antibiotic for the treatment of Clostridium difficile infection Hospital acquired bacterial infections continue to be a significant burden to the healthcare system and to patient welfare due to ever increasing rates of antibiotic resistance and the rise in prevalence of emerging and hard to treat infections.

 One of the most important of these, Clostridium difficile, is a typically harmless bacteria that under certain conditions can cause a life-threatening infection of the colon. In particular, C. difficile infection (CDI) is associated with antibiotic use, which can cause an imbalance in the healthy bacterial population of the gut resulting in an overgrowth of C. difficile.  There are estimated to be around 900,000 cases of CDI each year across North America and the EU and the infection now accounts for >80% of deaths due to gastroenteritis. Of particular concern are outbreaks due to hyper-virulent strains of the bacteria that are responsible for more severe forms of the disease. Antibiotic choices for CDI are limited and of sub-optimal efficacy with up to  30 per cent of patients suffering at least one recurrence of the infection. Each recurrence  tends to be more severe and is associated with increased risk of further infection. Combatting recurrent disease remains the central issue in achieving effective therapy for this life threatening infection.

SMT19969 is a novel antibiotic being developed by Summit Corporation PLC for the specific treatment of CDI. SMT19969 shows high levels of selectivity for C. difficile whilst having minimal effect on the normal healthy gut bacteria, which is expected to result in a significant healthcare benefit by reducing rates of recurrent disease. Preclinical development was funded by a Wellcome Trust Seeding Drug Discovery award. With continuing support via a Translation Award to Summit Corporation PLC  the company is now undertaking Phase I first-in-man safety studies and Phase II efficacy trials.
 
Clinically practical two- and three-dimensional ultrasonic elasticity imaging
Seeding Drug Discovery Discovery and development of novel small molecule inhibitors of the human Hyperpolarization activated
Cyclic Nucleotide-gated 2 (HCN2) ion channel for the treatment of inflammatory and neuropathic pain
Treatments for inflammatory pain (IP) and neuropathic pain (NP) are frequently ineffective and have many side effects. Scientists in Professor Peter McNaughton's laboratory at the University of Cambridge have discovered that both IP and NP are abolished in mice when an ion channel is genetically deleted. This suggests that drugs blocking this ion channel will have value as novel analgesics.

IP is associated with injury, infection or chronic conditions such as arthritis; and NP is caused by nerve damage in conditions such as post-herpetic neuralgia and diabetic neuropathy. Both IP and NP can impose major limitations on lifestyle and working patterns and currently available treatments have major drawbacks. For example, non-steroidal anti-inflammatories cause gastric and renal damage; and opioids cause constipation and problems with tolerance and addiction. The team aims to develop selective ion channel blockers, which avoid those that play essential roles in the heart and brain, and test them in animal models of IP and NP. In separate parallel studies they will use a known non-selective blocker to carry out proof-of-principle studies in human NP.
FLIP FADD
Seeding Drug Discovery Small molecule inhibitors of the anti-apoptotic FLIP-FADD protein-protein interaction for the treatment of non-small cell lung cancer In most organs and tissues, old cells are constantly dying and being replaced by new cells. This balance is critical for normal organ/tissue function and is maintained by a balance between new cells being created by cell division and old cells dying by a process known as "apoptosis".

One of the key characteristics of cancers is that the old cells do not die efficiently by apoptosis and therefore accumulate giving rise to a tumour that ultimately disrupts organ function.  This block in apoptosis is also a major problem when it comes to treating cancers as the effectiveness of chemotherapies and radiotherapies usually rely on their ability to activate this type of cell death.  Professor David Haighıs team at Queenıs University of Belfast have identified an intra-cellular protein called "FLIP" that plays a critical role in preventing the death of cancer cells treated with chemotherapy and radiotherapy. This protein plays a prominent role in increasing the resistance to therapy in a number of types of cancer,  including non-small cell lung cancer, which is a particularly drug-resistant cancer and is the focus of this proposal. The project team plan to generate drugs to block FLIP's function and thereby overcome drug resistance and improve the therapeutic management of patients with this disease.
Trapani
Seeding Drug Discovery Perforin Inhibitors for the prevention of allogenic bone marrow stem cell transplant rejection Perforin is a novel and tractable target, the inhibition of which would address significant unmet need in clinical allotransplantation and potentially, a number of other human disorders. An immunosuppressant targeting perforin would provide the first-ever therapy focussed specifically on one of the principal cell death pathways leading to transplant rejection.

The Trust has awarded AU$6.8m over three years to Professor Joe Trapani (Peter MacCallum Cancer Centre), Professor Bill Denny (University of Auckland), Professor James Whisstock (Monash University) and Professor Geoff Hill (Queensland Institute for Medical Research) for the development of small molecule inhibitors of perforin that could lead to more prevention of allogeneic bone marrow stem cell transplant rejection and therefore increase survival rates for many forms of cancer. The team led by Professor Joe Trapani, have recently developed three classes of compounds which have been shown to block the action of perforin. Under the Trust funding the team will continue to characterise and improve on these compounds. These inhibitors will be assessed in specific models and then progressed into clinical candidates that could be ultimately assessed in drug trials for indications with significant unmet clinical need.
Development of novel analogues of the satiety hormone pancreatic polypeptide (Y4 receptor agonists) as an anti-obesity agent
Seeding Drug Discovery Development of PP 1420 for the treatment of obesity Obesity is a worldwide pandemic. The only licenced medical therapy for obesity in the UK is a lipase inhibitor, orlistat, which, while safe, has significant side effects and produces only moderate weight loss

Bariatric surgery is effective, but is expensive, inflexible and carries a significant mortality rate. There is therefore an unmet need for new medical treatments. Gut and pancreatic hormones, secreted post-prandially, naturally reduce appetite via feedback mechanisms. These hormones are therefore promising anti-obesity drug development targets.

Professor Sir Steve Bloom, Imperial College and his team have developed a degradation resistant peptide analogue of the hormone pancreatic polypeptide called PP 1420 that is a specific agonist of the neuropeptide Y subtype 4 (Y4) receptor, with the following features:
• administered subcutaneously as a treatment for obesity.
• composed of all natural amino acids, without modifications
• capable of reducing food intake and body weight when given to animal models of obesity
• appeared free of side effects.
Funded by a Wellcome Trust Seeding Drug Discovery Award, the team has developed PP 1420 from pre-clinical to a Phase 1 first time in man study.  PP 1420 was found to be well-tolerated and not significantly toxic in statutory pre-clinical studies in two species. A GLP-compliant assay in a human plasma matrix for PP 1420, based on LC/MS-MS, was developed.
 
• A Phase 1 study was conducted by the research team in the Sir John McMichael Centre at Hammersmith Hospital. When administered to healthy human volunteers at doses ranging from 2-8 mg in this study:
• No adverse effects were seen.
• No evidence of peptide immunogenicity.
• Maximal plasma concentrations were seen at approximately 1 hour after subcutaneous injection.
• The terminal elimination half-life was estimated at approximately 2.5 hours.
• Systemic exposure (AUC0-8 and Cmax) was proportional to the dose.

11b-Hydroxysteroid Dehydrogenase Type 1 (11b-HSD1) Inhibition: tissue-specific control of cortisol action
Seeding Drug Discovery 11b-HSD1 inhibition for disease modification and symptom control in Alzheimer's disease Professor Brian Walker, Professor Jonathan Seckl and Dr Scott Webster, University of Edinburgh have identified 11b-HSD1 as a crucial amplifier of glucocorticoid action in liver, adipose tissue and CNS, have shown its pathophysiological significance in obesity, and have provided preclinical and clinical 'proof of concept' that 11b-HSD1 inhibition improves both Metabolic Syndrome and cognitive function in ageing.

Although their work has fuelled intense commercial interest in developing 11b-HSD1 inhibitors for metabolic indications, including type 2 diabetes, the opportunity to improve cognitive function has not yet attracted pharmaceutical companies.  Under the latest round of funding, they will select the optimal clinical candidate and aim to progress these to Phase I clinical trials aiming at a memory improvement.
Seeding Drug Discovery Development of a type B lantibiotic for treatment of Clostridium difficile infection C. difficile infection (CDI) has increased in incidence and severity through the last decade to become the major cause of mortality amongst nosocomial infections. Currently, there are very few therapeutic options for CDI and recurrence of disease after initial successful therapy is a major health problem and burden to healthcare systems.


Novacta Biosystems Limited has embarked on development of a class of agents called type B lantibiotics which inhibit bacterial cell wall biosynthesis. The agents have promising properties for treatment of CDI in that given orally they are stable in the gastro-intestinal tract and not absorbed, their mechanism of action provides a good resistance prognosis and they have low toxicity. Starting with the discovery of a new lantibiotic, deoxyactagardine B, a combination of biosynthetic modification at the genetic level and semi-synthetic chemistry yielded NVB302, a drug candidate with excellent activity against C. difficile and very little activity against the predominantly Gram-negative gut flora. This selectivity is believed to be important to allow the colonic flora to restore a barrier to re-infection.

NVB302 is currently undergoing a phase I clinical trial in healthy volunteers.
Retinoic acid receptor a agonists for the treatment of Alzheimer's disease
Seeding Drug Discovery Identification of retinoic acid receptor b agonists for the treatment of spinal cord injury There are as yet no effective treatments for spinal cord injuries (SCI). The Trust has awarded £3.6 million over 42 months to Dr Jonathan Corcoran, Dr Barret Kalindjian and Professor Thomas Carlstedt for the development of orally available small molecules for the treatment of SCI.

Researchers led by Dr Jonathan Corcoran have identified a novel signalling mechanism - the retinoic acid receptor b (RARb) signalling pathway - that can be stimulated in models of SCI leading to axonal outgrowth and functional recovery. The pathway is activated by small molecules known as retinoids and leads to the modulation of various proteins that are known to be involved in axonal outgrowth. The award will allow the identification of novel RARb agonists which can be given orally to patients with SCI. Their use will be demonstrated in rodent models of SCI, and the work will ultimately lead to a clinical trial in human avulsion injury, which is one of many types of SCI.

Seeding Drug Discovery Discovery of new drugs for the prophylaxis and treatment of dengue virus infections in humans The dengue virus is endemic in most tropical and sub-tropical regions around the world, predominantly in urban and semi-urban areas.  According to the World Health Organization 2.5 billion people, of which 1 billion children, are at risk of dengue infection.

 
An estimated 50 to 100 million cases of dengue fever, half a million cases of severe dengue disease and more than 20 000 deaths occur worldwide each year. Dengue is a leading cause of hospitalization and death amongst children in regions where dengue is present.  There is no vaccine, nor a specific treatment or prophylaxis for dengue. 

With Welcome Trust funding, Professor Johan Neyts (Rega Institute) together with the Centre for Drug Design and Discovery (CD3) at the University of Leuven(KULeuven) identified a novel class of potent inhibitors of dengue replication.  The lead compounds in this series elicit activity against all four dengue serotypes with a large therapeutic window. This class of small molecule inhibitors has a good ADME-Tox profile and targets the virus via a unique mechanism.  Furthermore the barrier to resistance is high and once obtained, the fitness of such variants is low.  The project is now in a lead optimisation phase.
Inhibitors of Lysyl Oxidase for the Prevention and Treatment of Invasive and Metastatic Cancer
Seeding Drug Discovery Inhibitors of Lysyl Oxidase for the Prevention and Treatment of Invasive and Metastatic Cancer The enzyme lysyl oxidase (LOX) regulates cross-linking of structural proteins in the extracellular matrix.

LOX also plays a role in stimulating the metastatic spread of cancer through the body. Its expression is increased in hypoxic cancers and is correlated with tumour metastasis and decreased patient survival. In model systems its inhibition significantly decreases cancer metastasis and increases survival. Since metastasis is responsible for over 90 per cent of cancer deaths these data validate LOX as an important therapeutic target in cancer. Professor Caroline Springer and Professor Richard Marais from the Institute of Cancer Research have been awarded Seeding Drug Discovery funding to develop drugs that target LOX. They are applying a medicinal chemistry drug discovery approach underpinned by a strong programme in LOX biology with the aim of producing orally available, small molecular weight drugs that inhibit LOX activity for cancer treatment.See our video: BRAF and cancer: collaborative drug discovery
Discovery and development of novel small molecule inhibitors of the human cardiac acetylcholine activated current (IKACh) for the treatment of atrial fibrillation
Seeding Drug Discovery Novel small molecule inhibitors of the human cardiac acetylcholine activated current (IKACh) for the treatment of atrial fibrillation
Atrial fibrillation (AF) is an abnormal, disorganised, cardiac rhythm that originates in the upper chambers (atria) of the heart. It is the most common sustained cardiac arrhythmia encountered in clinical practice, with around 12 million sufferers worldwide and is gaining in clinical importance as the population ages.

AF is clinically significant because it contributes to the incidence of stroke and overall cardiovascular morbidity and mortality. Patients with AF have a five-fold increased risk for stroke; indeed, in the US approximately 15-25 per cent of all strokes can be attributed to AF. The treatment of AF is controversial and often problematic. Whereas electrical cardioversion restores sinus rhythm in many patients with AF, the maintenance of sinus rhythm often requires chronic treatment with anti-arrhythmic drugs. Although there is a consensus amongst cardiologists that sinus rhythm control with anti-arrhythmic drugs is the preferred and most effective treatment of AF, none of the existing drugs are able to maintain rhythm without significant negative side effects. Consequently new anti-arrhythmic drugs are desperately needed.  Xention Limited has received Seeding Drug Discovery funding to develop an orally active drug for the safe and effective treatment of AF with a substantially improved safety profile compared to current therapies.

Seeding Drug Discovery Allergen Delivery Inhibitors:  Preclinical evaluation Allergen Delivery Inhibitors offer the potential to combine alleviation of asthma with allergy prophylaxis using small molecule inhaled therapy.

Researchers at St George’s, University of London and the University of Manchester have employed structure-based drug design to develop inhibitors that selectively target house dust mite cysteine peptidases, enzymes that make significant contributions to the development, maintenance and escalation of allergic diseases including asthma. The programme’s candidate drug (CD 1) displays in vivo efficacy in animal models with a good duration of action when delivered to the airways. CD 1 is supported by several developable back-up compounds from chemically distinct and mechanistically distinct series. A patent portfolio is being created and Technology Transfer is seeking a development and commercialisation partner for this programme.

Seeding Drug Discovery Discovery and development of novel glioblastoma treatment that selectively reduces Bmi-1 expression in tumour stem cells BMI1 is a well-established oncogene that has been shown to be over expressed in tumour cells and necessary for cancer stem cell survival. PTC was awarded funding through the Wellcome Trust Seeding Drug Discovery initiative to identify novel small molecules that target BMI1.


It is widely accepted that a subpopulation of tumor cells, possessing intrinsic chemo-resistance and expressing many characteristics of normal stem cells, is responsible for treatment failure and relapse across multiple tumor types. BMI1 is a transcriptional repressor necessary for efficient cell division necessary for the renewing of adult hematopoietic stem cells as well as adult peripheral and central nervous system stem cells. BMI1 is widely over-expressed in human cancers and is critical in the development of glioblastomas, leukemias, lymphomas, and lung cancers. The level of BMI1 protein is positively correlated with disease grade and poor prognosis. By inhibiting BMI1 protein function and levels, PTC is targeting the resistant cancer stem cell fraction within tumours. 

PTC has identified compounds that potently reduce the levels of endogenous BMI1 protein in multiple cell lines at low nanomolar concentrations. Consistent with the function of BMI1, PTC?s compounds preferentially kill tumor cells, and in particular tumor stem cells, sparing normal primary progenitor cells.  PTC?s compounds selectively decrease the level of BMI1 in vivo on oral dosing in pharmacodynamic xenograft models of several tumor types. At higher doses of compound, this inhibition resulted in a nearly total control of tumor growth in multiple xenograft models of fibrosarcoma, glioblastoma, and leukemia. The program is currently in late lead optimization with the goal of identifying an orally available Development Candidate for the treatment of chemotherapy- and radiation-resistant cancers.

Seeding Drug Discovery Development of a novel class of antibiotics for the targeted treatment of Clostridium difficile infection Recent years have seen increasing publicity surrounding the rise of the so called hospital superbug. One of the most important of these, Clostridium difficile, is typically harmless, but under certain conditions can cause a life-threatening infection of the intestine. In particular, C. difficile infection (CDI) is associated with prior antibiotic use causing an imbalance in the normal bacterial population of the gut resulting in an overgrowth of C. difficile.

The infection now accounts for over three times as many deaths in the UK than infections due to MRSA. In the UK alone there were over 36 000 cases reported in the year ending March 2009 and several thousand deaths. Antibiotics for CDI are limited, of sub-optimal efficacy and are associated with around a 30 per cent relapse rate with each period of relapse invariably resulting in more severe forms of the disease.   Summit plc is developing novel, highly specific antibiotics for CDI with SMT19969, the lead compound from the programme, currently in late stage preclinical development.  SMT19969’s highly selective killing of C. difficile, without affecting the normal healthy gut bacteria, is expected to result in a significant healthcare benefit by reducing rates of relapse which remains the central clinical issue in CDI management.The programme is being funded by the Seeding Drug Discovery Initiative which has enabled Summit to accelerate the development of SMT19969 as a much needed therapy for a life threatening infection.
Development of highly-selective β1 adrenoceptor antagonists for therapeutic application in patients with concomitant cardiovascular and respiratory disorders
Seeding Drug Discovery Development of highly selective beta-1 adrenoceptor antagonists Development of highly selective beta-1 adrenoceptor antagonists Beta blockers have a serious side-effect of causing airway narrowing, shortness of breath and wheezing, and cannot be taken by patients with both heart and lung diseases.


Dr Jillian Baker, Professor Steve Hill, Dr Barrie Kellam and Professor Peter Fischer at the University of Nottingham have been awarded funding to develop highly selective beta-1 antagonists. The programme is based around a lead compound with over 3000-fold beta-1 selectivity and demonstrated activity in an in vivo animal model. Once developed, the group's drug candidate will by definition have less respiratory side-effects and should be able to be given safely to the hundreds of thousands of patients with both heart and lung diseases.
Seeding Drug Discovery Novel bacterial DNA synthesis inhibitors for the treatment of nosocomial infections caused by multi-drug resistant Gram-negative bacteria PTC Therapeutics, Inc. (PTC) has been awarded funding from the Seeding Drug Discovery initiative for a programme targeting the treatment of infections caused by multidrug-resistant Gram-negative bacteria.  PTC has identified a novel structural class of molecules that selectively inhibit bacterial DNA synthesis and have bactericidal activity.

These molecules are predominantly active against Gram-negative bacteria although several analogs in the series also have activity against Gram-positive species, including methicillin-resistant S. aureus (MRSA). The PTC compounds are potent against Gram-negative bacteria that are resistant to marketed antibiotics. Representative compounds have good pharmaceutical properties and are efficacious in murine models of systemic E. coli infection. The anti-infective program at PTC is currently in lead optimization and advancing towards identifying a development candidate as a potential first-in-class drug for the treatment of life-threatening infections caused by Gram-negative multidrug-resistant bacteria.

Seeding Drug Discovery Development of a small molecule inhibitor of EBNA1 to treat Epstein-Barr Virus (EBV) Latent Infection and Associated Disease Epstein-Barr Virus (EBV) is estimated to be responsible for ~1% of all human cancers worldwide including Burkitt's lymphoma, nasopharyngeal carcinoma, Hodgkin's lymphoma, gastric carcinoma, NK/T cell lymphoma, and lymphoproliferative disease in the immunosuppressed.

The World Health Organisation classifies EBV as a type I carcinogen. Maintenance of latent EBV in infected cells depends on the continuous expression of one viral protein, EBNA1. The essential role of EBNA1 in cell proliferation, transformation and lymphomagenesis associated with EBV malignancies makes it an attractive target for drug discovery and development.

Recently, the crystal structure of EBNA1 has been determined and revealed a druggable surface within its DNA binding domain. Exploiting this property, the team of Professor Lieberman at the Wistar Institute in Philadelphia completed a successful high-throughput screening campaign. Supported by a three year Seeding Drug Discovery award the team will now use medicinal chemistry and structure-based drug design methods to optimize promising starting points into small molecule inhibitors of EBNA1. The goal of this project is the development of a pre-clinical candidate ready to be taken into Phase 1 first in human clinical trials. This innovative project has the potential to deliver a completely novel anti-viral in a field of significant unmet medical need.
Seeding Drug Discovery Development of a membrane-targeted antibiotic for complicated skin and skin structure infections caused by multidrug-resistant bacteria The lack of treatments currently available for multi-drug resistant bacteria is one of the most pressing global health issues today. This crisis has been clearly noted by key UK, European and US opinion leaders and government organisations.

Professor Matthew Cooper and his colleagues at the University of Queensland have received a Seeding Drug Discovery award to help to address this problem. The team are using a natural product which has been modified to bind more tightly to bacterial membranes, and not bind to human cell membranes. They plan to develop this modified natural product into a ?best in class? antibiotic for the treatment of infections by bacteria and resistant superbugs.
Seeding Drug Discovery Development of a preclinical drug candidate for treatment of visceral leishmaniasis through optimisation of scaffolds identified from a phenotypic HTS screen of L. donovani axenic amastigote proliferation Leishmaniasis is a widespread parasitic disease with frequent epidemics in the Indian subcontinent, Africa, and Latin America.  The disease is responsible for ~50K of deaths each year, and substantial morbidity.

In its most severe form, visceral leishmaniasis (or kala-azar), the disease is characterized by parasitic invasion of internal organs, and is almost always fatal if left untreated. Several drugs are available but these suffer from multiple shortcomings such as toxicity, failure of treatment due to parasite resistance, and length and cost of treatment. From extensive high throughput screening of compound libraries, a research team led by Dr Richard Glynne at the Genomics Institute of the Novartis Research Foundation have identified several chemical scaffolds that selectively kill Leishmania parasites at concentrations having no effect on human cells. The aim of the project is to optimize these scaffolds towards the identification of an orally available small molecule with efficacy in mouse and hamster models of visceral leishmaniasis. Such a compound would be suitable for toxicity studies in support of clinical testing.
SEEDING DRUG DISCOVERY Identification of PARP inhibitors for cancer therapy While effective treatments for many forms of cancer exist, therapies that are tailored for patients with niche forms of the disease, such as triple negative breast cancer are currently unavailable.

The Trust has awarded £3.9 million over three years to Prof. Alan Ashworth, FRS, Dr. Christopher Lord, Prof. Caroline Springer and Prof. Laurence Pearl, FRS, for the development of orally available small molecules that could target specific cancer subtypes.
Researchers led by Prof Alan Ashworth and Dr Christopher Lord have pioneered the exploitation of novel therapeutic approaches such as synthetic lethality and the use of PARP inhibitors in cancer treatment. PARP (Poly ADP-Ribose Polymerase) enzymes modify proteins and control cell function by catalyzing the addition of poly (ADP-ribose) polymers onto substrates. With funding from the Trust, Ashworth, Lord, Springer and Pearl, in collaboration with Domainex, will develop novel small molecule inhibitors that target additional PARP superfamily members. These inhibitors will be assessed in specific tumour models and then progressed into clinical candidates that could be ultimately assessed in drug trials that target cancer subtypes for which there is significant unmet clinical need.
Fragment-based approaches to the design of candidate drugs that interrupt protein-protein interactions involved in cell regulation
Seeding Drug Discovery The use of fragment-based drug discovery to identify novel drug candidates that modulate the BRCA2-RAD51 interaction for the treatment of cancer The Trust has awarded over £2.4 million to Chris Abell, Tom Blundell, Marko Hyvonen, Grahame McKenzie and Ashok Venkitaraman at the University of Cambridge to use fragment-based approaches to design and make molecules that disrupt the interaction of two important proteins in human cells, the recombinase RAD51 and the product of the breast cancer-associated gene BRCA2.

These proteins are involved in the repair of DNA breakage, and blocking their interaction should result in sensitization of cancer cells to DNA damage, e.g. by radiation, or directly induce cancer cell death during proliferation. Potent compounds will be developed by synergistic use of X-ray crystallography and synthetic organic chemistry, and improved in a highly focused way to make sure they are safe and suitable for development into possible drug candidates. The lead compounds will be tested against different cancer cell lines to identify susceptible cancers, the most probable therapeutic target being lung cancer. This funding follows on directly from a Translation Award to pioneer the use of fragment-based approaches against protein-protein interactions. That project established the use of biophysical methods, especially NMR spectroscopy and X-ray crystallography to identify fragments that bound at specific sites on a protein interface and to iteratively grow these fragments into successively more potent compounds.
A new approach to the treatment of invasive pneumococcal diseases using drugs that inhibit the activity of a pneumococcal virulence factor
Seeding Drug Discovery A new approach to the treatment of invasive pneumococcal diseases Streptococcus pneumoniae causes a very high number of cases of pneumonia, meningitis and bacteraemia, worldwide.

Despite using antibiotics that kill the bacterium, a large number of patients still die and in meningitis, many survivors have profound neurological handicap. This is because the bacterium produces a very damaging virulence factor that is not inhibited by antibiotics. This problem constitutes an unmet medical need that Professor Peter Andrew and colleagues from the University of Leicester are proposing to fulfill. They have identified that small molecules can inhibit this virulence factor and are effective in vivo. The team have been awarded funding through the Seeding Drug Discovery initiative to identify new small molecules and through a programme of medicinal chemistry, combined with in vitro and in vivo testing, to identify lead compounds with appropriate efficacy, pharmacokinetics and toxicology. The aim is that giving such molecules will reduce the number of patients that die or suffer handicap as a result.
Treatment for community and hospital MRSA infections
Seeding Drug Discovery Treatment for community and hospital MRSA infections Antibacterial research within GlaxoSmithKline has received an award to fund discovery of a novel antibiotic agent for treating infections caused by methicillin-resistant Staphylococcus aureus (MRSA).

Over the past few years the prevalence of invasive MRSA has significantly increased worldwide including the UK and continental Europe and the US, where it is now estimated to cause more deaths than HIV. This is now a very serious and growing public health issue that needs to be addressed. The GSK-Wellcome Trust research program will build on both the extensive GSK knowledge of structure-activity relationships for this novel class of antibacterial molecules, and the considerable learnings from advanced studies on previous compounds from this series. GSK's expertise in this area, coupled with the promise of new SAR from an innovative medicinal chemistry strategy, gives a high probability of success on delivering a much-needed novel MRSA drug candidate.
Development of fragment-based Hepatitis C (HCV) viral replication inhibitors
Seeding Drug Discovery Development of fragment-based Hepatitis C (HCV) viral replication inhibitors An estimated 170 million people worldwide are infected with HCV with treatment requiring an extended period of therapy and influenced by side effects and low response rates.

The Trust has provided £2 million programme related investment to Cambridge based Astex Therapeutics to use their proprietary fragment-based screening approach, Pyramid (TM), to identify and develop novel inhibitors which bind to newly identified regulatory site on a HCV viral protein. Such novel agents would be of significant value in a disease where combination therapy is vital to limiting the emergence of viral resistance.
Alternative complex I as a drug target in malaria
Seeding Drug Discovery Alternative complex I as a drug target in malaria The Liverpool School of Tropical Medicine (Professor Stephen Ward and Dr Giancarlo Biagini) and Liverpool University (Professor Paul O'Neil) have been awarded £1.4 million to develop a drug against multidrug resistant malaria (Plasmodium falciparum).

The award will fund a multidisciplinary team of medicinal and in silico chemists, pharmacologists and molecular parasitologists for two years.The project aims to develop inhibitors to candidate selection against a novel component of the parasite's electron transport chain.
Development of Novel Aminoglycosides for the Treatment of Multi-Drug Resistant Gram-Negative Bacteria, including MRSA and Enterobacteriaceae
Seeding Drug Discovery Novel aminoglycosides for the treatment of multi-drug resistant Gram-negative bacteria Aminoglycosides are a proven class of antibacterials that remain in extensive clinical use despite growing drug resistance.

The Trust has provided a programme-related investment of $8 million (£4.1 m) to San Francisco based Achaogen Inc, to develop novel aminoglycoside compounds to tackle emerging resistance. Achaogen will progress a lead scaffold with activity against Staphylococcus aureus and highly resistant Enterobacteriaceae and a separate chemical series with extended spectrum that also includes multi-drug resistant Acinetobacter baumannii and Pseudomonas aeruginosa. Both scaffolds will be advanced via in vitro and in vivo efficacy, pharmacokinetic, and safety assays, culminating in the identification of a clinical candidate.
Retinoic acid receptor a agonists for the treatment of Alzheimer's disease
Seeding Drug Discovery Retinoic acid receptor a agonists for the treatment of Alzheimer's disease The current licensed treatments for Alzheimer's disease improve the symptoms that people experience but do not alter the progression of the underlying disease changes in the brain.

Most of the attempts to develop new treatments have focused on altering deposits of the amyloid protein in the brain, but despite more than a decade of intensive research this has still not yielded any new therapies in the clinic. The studies of Dr Jonathan Corcoran of King's College London highlight a specific retinoic acid receptor (RAR)a agonist as a novel and exciting target for the development of new treatments. This agonist has two mechanisms of action - it regulates amyloid deposits in the brain and also plays a key role in the survival of neurons. In their project they will generate novel RARa agonists for the treatment of Alzheimer's disease.
Dimethylarginine dimethylaminohydrolase 1 inhibition in sepsis
Seeding Drug Discovery Dimethylarginine dimethylaminohydrolase 1 inhibition in sepsis Sepsis, a severe inflammatory infection, is the major cause of death in patients in intensive care units.

A dramatic fall in blood pressure (hypotension) in septic patients contributes to death. Current strategies to block this hypotension are only partially effective and carry side effects that might reduce patient survival. One of the mechanisms that causes hypotension is the over production of a molecule, nitric oxide (NO), which causes blood vessels to dilate. A multidisciplinary collaboration of scientists, lead by Professor James Leiper, from the departments of Medicine and Chemistry at University College London together with structural biologists from Birkbeck College have identified a novel mechanism to block hypotension in sepsis. This approach works by increasing the level of a naturally occurring compound (asymmetric dimethylarginine, ADMA), which inhibits NO production. This project aims to identify and characterise small drug-like molecules that increase the level of ADMA and will therefore have therapeutic utility in the treatment of sepsis. The research team is uniquely placed and propose to test their candidate molecules for safety in healthy humans in the third year.
Selective glucocorticoid receptor agonists for the treatment of inflammatory conditions
Seeding Drug Discovery Selective glucocorticoid receptor agonists for the treatment of inflammatory conditions Research by Professor David Ray and his team at University of Manchester has identified how to modulate the function of the glucocorticoid receptor.

The glucocorticoid receptor responds to both natural hormones and synthetic glucocorticoids to inhibit the inflammatory response. Inflammation lies behind many important human diseases, including rheumatoid arthritis, and opening up novel approaches for therapy offers new hope for these chronic, disabling conditions. The award will allow development of new molecules capable of harnessing the glucocorticoid receptor for treatment of multiple inflammatory diseases, without the wide range of side effects that currently limit use of conventional drugs. If successful the research will lead to an orally active drug for use in inflammatory arthritis within five years.
Transthyretin depletion for the treatment of hereditary systemic and senile cardiac amyloidosis
Seeding Drug Discovery Transthyretin depletion for treatment of hereditary systemic and senile cardiac amyloidosis Systemic transthyretin amyloidosis is a fatal late onset disease caused by tissue deposition of amyloid fibrils composed of variant and wild type transthyretin.

Pentraxin Ltd, a spin-out from University College London and headed by Professor Mark Pepys has been awarded funds to construct compounds targeting plasma transthyretin, which could be used as drugs for treating and preventing acquired and hereditary human systemic transthyretin amyloidosis. The aim is to optimise the design, synthesis, and properties of a transthyretin targeting drug and complete the comprehensive safety and efficacy evaluation required prior to administration of a validated candidate compound in humans.
Targeted Synergy: Hypoxia-targeted small molecules that deliver synergistic therapeutic activities for the treatment of glioblastoma
Seeding Drug Discovery Targeted Synergy Hypoxia-targeted small molecules that deliver synergistic therapeutic activities for the treatment of glioblastoma.

Sentinel Oncology, a drug discovery company focused on developing next drugs for cancer, and Professor Ashok Venkitaraman, University of Cambridge have collaborated to develop a new technology, Targeted Synergy, which is designed to overcome the twin problems of toxicity and drug resistance in cancer chemotherapy. The majority of cancer patients receive treatment with radiation or radiomimetic drugs, but cancer cells are often resistant to these agents, and they cause toxic side effects. Targeted Synergy works by combining two synergistic effects in a single molecule that is activated selectively in cancer cells to help overcome resistance and kill them with less general toxicity to the patient. The principles behind Targeted Synergy incorporate Professor Ventikaraman's research, which have been exploited by the Sentinel Oncology team to create several new classes of drugs that work in this way. Sentinel's Targeted Synergy drugs are expected to be particularly useful in the treatment of brain tumours, for which an effective treatment is not currently available.
Novel antibacterials for Gram-negative pathogens
Seeding Drug Discovery Novel antibacterials for Gram-negative pathogens Wellcome Trust and GlaxoSmithKline have announced a collaboration to develop a new class of antibacterials to combat the rise of certain drug-resistant hospital-acquired infections, including those that lead to pneumonia.

GlaxoSmithKline (GSK) has received a £4 million award to accelerate development of compounds for the treatment of Gram-negative bacteria, which are becoming increasingly resistant to multiple antibacterials. The research will target Gram-negative bacteria, such as Pseudomonas, Klebsiella and Acinetobacter, which are increasingly resistant to available antibacterials and commonly cause hospital-acquired pneumonia and septic shock, particularly in patients in intensive care units. Without adequate therapy, patients often confront a poor prognosis - mortality is high, and recovery, when it occurs, can be long and complicated. Virtually no novel-mechanism antibacterials are in development to address this rising need. Gram-negative bacteria are particularly difficult to attack as they have an outer membrane surrounding the bacterial cell wall, which interferes with drug penetration. New medicines must not only be toxic to the pathogen, but must first overcome the barriers to entry into the cell.
Anti-MRSA nasal product
Strategic Translation Award Anti-MRSA nasal product Phico Therapeutics Ltd has been awarded a £1.03m to cover Phase I and II trials of its lead candidate SASPject (TM) PT1.2 for nasal decolonisation of MRSA and S. aureus.

PT1.2 is based on a new class of antibacterial proteins called SASPs, which bind to bacterial DNA resulting in rapid speed of kill. Phico Therapeutics envisages developing a fast-acting, easily applicable nasal gel which would combat both hospital and community MRSA transmission and drug-resistance. There is an urgent need to develop innovative ways to manage the transmission of antibiotic-resistant bacteria in the hospital and care-home environments and if successful, this technology may provide an important new tool in the fight against MRSA and other pathogenic bacteria.
Mintaka Foundation
Strategic Translation Award Clinical Development of a Chemokine Anti-HIV Microbicide HIV/AIDS is being brought under control in wealthy countries, but more than 2 million new infections occur per year in the developing world, more than 95 per cent of the global total. Women and girls are often unable to negotiate any form of protection for themselves, and thus are particularly at risk.

In Africa south of the Sahara 75 per cent of all young people infected are female. There will be no effective vaccine for years and many hopes rest on 'microbicides', substances that could be applied to the vagina before sex and that would prevent infection. At present, a microbicide effective against HIV is not available: such a substance would greatly empower women and girls to protect themselves and their partners by a method under their control. 5P12-RANTES is an extremely potent anti-HIV substance, suffers very little from the common problem of generating drug-resistant strains, can be produced cheaply by fermentation in yeast and is highly resistant to tropical temperatures. Mintaka will use the funds granted to develop and execute a larger scale preparation method to cGMP standards, study stability and formulation, and execute some remaining animal toxicity tests that are required before 5P12-RANTES can be used in humans.
The Novartis Institute for Tropical Diseases: Malaria Drug Discovery
Strategic Translation Award The Novartis Institute for Tropical Diseases: Malaria Drug Discovery An international research partnership has embarked on a programme to discover and develop a new generation of antimalarial drugs.

The Wellcome Trust, the Singapore Economic Development Board and the Medicines for Malaria Venture (MMV) have pledged over £10 million in funding, while the Novartis Institute for Tropical Diseases (NITD) will manage the programme and conduct research jointly with several institutions, including the Genomics Institute of the Novartis Research Foundation and the Swiss Tropical Institute. One of the top three killer diseases in tropical countries, malaria is estimated to kill over one million people and affect around 300-500 million people annually. Research at Singapore-based NITD will focus on the development of a one-dose cure for Plasmodium falciparum, the most dangerous form of malaria, and a new way to cure Plasmodium vivax, the most frequent and widely distributed cause of malaria.
Translation Award Phase I dose escalation trial of a group B oncolytic adenovirus (ColoAd1) administered by intrahepatic artery infusion in patients with primary or secondary liver cancer The Wellcome Trust has awarded up to £1.8 million to PsiOxus Therapeutics to support clinical development of a virus that attacks cancer cells. Clinical trials of the virus in patients are expected to begin in early 2012.

Viruses that preferentially attack cancer cells whilst leaving normal tissues unharmed are known as oncolytic viruses. The oncolytic virus ColoAd1 was developed using the evolutionary principle of natural selection to generate a virus with preferred specificity for cancer cells as a possible new therapy for cancer.  Laboratory studies have shown that ColoAd1 has selectivity for killing cancer cells from a wide range of solid tumour types but shows little or no activity on normal tissue. Compared to other oncolytic viruses in development as cancer therapies, ColoAd1 has been shown to retain a high level of activity in human blood. This means that it could potentially be administered systemically as a treatment for cancer that has already spread to other tissues, known as metastatic disease.PsiOxus will use the Translation Award from the Wellcome Trust to conduct a phase I/II clinical trial of ColoAd1 in patients with metastatic colorectal cancer, to determine the safety and tolerability of the virus. Future studies are also planned in patients with other solid tumour types, including primary hepatocellular cancer and ovarian cancer.
Retinoic acid receptor a agonists for the treatment of Alzheimer's disease
Translation Award Development of a multi-peptide immunotherapeutic for Type 1 diabetes to first-in-human stage (MultipPepT1De) Type 1 diabetes (T1D) is an inflammatory disease in which cells making insulin (?-cells) are killed by the immune system. It arises predominantly in childhood, is increasing in incidence and carries significant risk of disease complications and early death, even when patients have repeated daily insulin injections. There is thus an imperative to find well tolerated strategies for treatment and or prevention of T1D.

Professor Mark Peakman at King's College London School of Medicine has been awarded funding to develop a strategy known as peptide immunotherapy. By introducing selected fragments of key proteins from ?-cells in a form that switches off inflammation, it is hoped that this therapy will "re-set" the immune system. Peptide immunotherapy is under development in other inflammatory diseases (allergy, multiple sclerosis) using cocktails of peptides, and shows considerable promise, as well as an excellent safety profile and the potential for long-lasting effects
Critical Pharmaceuticals
Translation Award Development of an hGH nasal spray for the treatment of growth disorders in children The Wellcome Trust has awarded Critical Pharmaceuticals Ltd. funding for the early clinical development of a nasal spray of human growth hormone using Critical Pharmaceuticals' novel CriticalSorb technology.

Human growth hormone is a large (22 kDa) protein drug used to treat growth disorders in children and adults. Biological drugs such as growth hormone are an increasingly important class of therapeutics and represent over 30 per cent of new drug approvals. However, 98 per cent of biological drugs are administered by frequent injection which is strongly disliked by patients and their carers. This can lead to poor patient compliance and sub-optimal clinical outcomes. Success in this project will see the development of the first nasal spray of a large biological drug and demonstrate the proof of principle of the CriticalSorb technology in humans. The CriticalSorb technology has the potential to enable the delivery of a wide range of biological drugs via nasal spray as an attractive alternative to injection.
cGMP Manufacture of T-cells for immunotherapy
Translation Award cGMP Manufacture of T-cells for immunotherapy Gregg Sando, Cellmedica has received translational funding to develop a cGMP procedure to isolate and prepare T-cells for anti-viral therapy.
T-cell immunotherapy has been shown to effectively treat viral infections on patients undergoing immunosuppression therapy, for example following transplant operations. Clinical availability of T-cells has been restricted in part due to regulatory issues. This project seeks to address the lack of a cGMP protocol for this approach, using established commercially available laboratory protocols and drawing together several clinical experts from across the UK.
