PROJECTS ESTABLISHED THROUGH THE MILNER CONSORTIUM
The Therapeutics Consortium agreement enables collaborative research between Consortium companies and academics across Cambridge. There are ongoing projects across ten Departments and Institutes of the University, and at the Babraham Institute. We have 19 collaborative projects between academics and pharma companies in total, 15 of which are highlighted below. The projects are broad in remit and can include access to compounds, datasets or know-how in a particular technique. In some cases, an industry scientist has come to work in the academic’s lab, and in others an academic post has been funded specifically for the project. The emphasis in all our collaborations is on mutual sharing of expertise. Please contact us if you are interested in finding out more.

CHEMISTRY: The use of artificial intelligence technologies to understand fragment-based screening. Astex are working with Lucy Colwell (Dept Chemistry) to develop machine learning methods for fragment-based drug discovery (FBDD). FBDD, which reveals <15kDa ligand interactions with biological targets, can be used to identify chemical starting points to generate new drug leads. It has advantages over conventional high-throughput screening because it enables screening of a much broader chemical space with fewer compounds; but often it uncovers lower affinity interactions. The machine learning methods will be trained using existing datasets to help understand what drives fragment binding and ultimately they will be applied to novel data to predict the binding of, and propose follow up, fragments. Fragment screening data and expertise from Astex will be used to inform the methods and to validate outputs. This project will provide an in-depth understanding of the utility of machine-learning methods in fragment binding drug discovery.
ONCOLOGY: Identifying potential therapies for early squamous lung cancer. Rational chemoprevention strategies are needed for intervention in patients at high risk of lung cancer. To better understand this disease, and devise potential approaches to detection and treatment, Frank McCaughan (Depts of Medicine and Biochemistry) has developed a novel model of early squamous lung cancer that recapitulates the key molecular and phenotypic features of the disease. In collaboration with the Lung Cancer Initiative at Johnson & Johnson (LCI), this organotypic model of bronchial dysplasia (OTC) will be used as a screening platform for potential therapeutic targets, using both compounds from Janssen R&D and genetic analysis with CRISPR and inducible shRNA.
ONCOLOGY: Strategies to influence T-cell mediated tumour killing. The majority of immune-oncology (IO) therapies are focused on enhancing the activity of tumour-killing CD8+ cytotoxic T-cells. Gillian Griffiths (CIMR and Dept Medicine) is working with AstraZeneca to determine pathways that enhance or reduce the ability of cytotoxic T cells to kill tumour cells.
ONCOLOGY: Investigating how different sub-types of breast cancer respond to different treatments. Breast cancer consists of a number of different genomic sub-types which makes effective treatment challenging and prognosis variable. Some sub-types respond well to particular drugs or drug combinations whereas others are resistant. Carlos Caldas (CRUK Cambridge Institute) is collaborating with AstraZeneca to investigate the different responses of breast cancer sub-types, using a bio-bank pioneered in his lab of breast cancer patient-derived tumour cells and tissues.

ONCOLOGY: Investigating modulators of the ERK/MAPK pathway. Simon Cook at the Babraham Institute is collaborating with Astex to investigate the significance of modulation of the ERK pathway in cell lines and the consequences for cancer cell growth inhibition and adaptive resistance. Targeting this pathway has been very successful in oncology therapy yet there remain many cancers that have an activated ERK pathway but do not respond to current BRAF or MEK inhibitors. The work will involve a detailed study of the ERK pathway and how it changes in response to different modes of inhibition. The aim is to understand better how ERK modulation affects cancer cell proliferation and apoptosis and how this may guide preclinical cancer research and drug discovery. Read more »
ONCOLOGY: Insights into the use of PROTAC molecules as a therapeutic strategy. Protacs (proteolysis targeting chimeric molecule), heterobifunctional nanomolecules that can recruit proteins to the ubiquitin-proteasome machinery for degradation, are being tested as a potential strategy for the treatment of cancer. Tony Kouzarides (Milner Institute and Gurdon Institute) is working with GSK to assess how a novel PROTAC molecule against a key epigenetic regulator affects cell proliferation, viability and division, and changes in gene expression, in a human cell model of acute myeloid leukaemia.
ONCOLOGY: Uncovering how Myc-mediated gene expression supports the tumour environment. Gerard Evan is collaborating with AstraZeneca to examine the role of the oncogene Myc in supporting the tumour environment.
ONCOLOGY: Strategies to prevent the progression to pancreatic adenocarcinoma. In a second project, Cathy Wilson working with Gerard Evan will collaborate with AstraZeneca to test the impact of inhibiting neutrophil influx on Myc-induced transition from pre-invasive pancreatic intraepithelial neoplastic lesions to pancreatic adenocarcinoma.
ONCOLOGY: Frank McCaughan (Depts Medicine and Biochemistry) has a novel organotypic model of early squamous lung cancer and is collaborating with AstraZeneca to determine novel targets for preventing tumorigenesis.
ONCOLOGY: Mechanisms of resistance to ALK inhibition in neuroblastoma. Suzanne Turner (Dept Pathology) is working with AstraZeneca to build on her previous in vitro studies indicating that inhibition of additional factors synergize with effects of ALK inhibition in neuroblastoma.
ONCOLOGY: Capturing the Early Stages of Acute Myeloid Leukaemia to Evaluate New Therapeutics. Bertie Göttgens (Stem Cell Institute) is working with AstraZeneca to test how combined therapeutic strategies can affect sequential disease stages of acute myeloid leukaemia including pre-leukaemia development in progenitor cells and development of resistance mechanisms against treatments.
INFECTIOUS DISEASE: Advancing disease understanding and drug discovery in infectious diseases. Pseudomonas aeruginosa — a pathogen that is lethal for many patients in hospital intensive care units — is also frequently associated with chronic airway infections in cystic fibrosis patients. The mechanism of infection is through the Type III Secretion (T3S) system, which is therefore a target for intervention strategies aiming to suppress pathogen virulence. The protein PcrV has been shown to be critical to virulence via the T3S system and antibodies against PcrV are being pursued as a potential therapeutic strategy. There are usually a number of microbial species present in an infection in addition to P. aeruginosa and it is also possible that inhibition of the T3S system may inadvertently increase antimicrobial resistance. Martin Welch (Dept Biochemistry) is therefore working with Shionogi to better understand i) the molecular mechanisms underpinning anti-PcrV antibody action, ii) how to quantify antibody action and iii) the wider consequences of inhibiting PcrV function on other cell processes. Knowledge, antibodies and assays are being shared between the two partners and a senior research scientist from Shionogi is working alongside academic scientists in the Welch lab to enable efficient transfer of knowledge and technical skills back in-house to Shionogi in Japan.

CNS DISEASES: Improving drug discovery in CNS diseases. Trevor Robbins (Dept of Psychology) and Angela Roberts (Dept of
PDN Cambridge), experts in the brain networks of the frontal lobes and their associated neurochemical systems that mediate cognition and behaviour, are working with Shionogi to test novel and first-in-class compounds on specific models of cognition and behaviour in rodents and marmoset monkeys. The combination of world leading academic knowledge and expertise in drug discovery will enable the development of new preclinical methods and models to evaluate cognitive and emotional functions that will improve candidate selection for mental health disorders.

CARDIOVASCULAR & METABOLISM: A drug re-purposing strategy for treatment of angina. Anthony Davenport (Dept of Medicine) is working with AstraZeneca to selectively block signalling by the potent vasoconstrictor endothelin that contributes to vasospasm in small coronary arteries in patients with angina.
