Scientists at The Institute of Cancer Research (ICR) have identified a breast cancer susceptibility gene, BRCA2, and advanced the understanding of the function of the BRCA genes. Following the discovery and cloning of BRCA2, further research demonstrated that BRCA mutations are also associated with ovarian, prostate and pancreatic cancers. BRCA testing is now routinely used by health services worldwide to identify those at high risk of developing cancer and advise them on preventative strategies. ICR research showed that magnetic resonance imaging (MRI) was more sensitive than X-ray mammography when screening for tumours in BRCA carriers, and this is now the standard of care in the UK. Through further research on BRCA function, ICR scientists demonstrated that PARP inhibitors were effective in treating breast cancer in mutant BRCA carriers. This has led to the rapid development of poly-ADP-ribose polymerase (PARP) inhibitors as drugs for targeted use against breast and ovarian cancers with a BRCA mutation as well as a recent submission to regulatory authorities for approval and registration in Europe for the use of the PARP inhibitor olaparib for maintenance treatment of BRCA mutated ovarian cancer.
Basic and applied research at the University of Cambridge has culminated in a widely-used risk prediction algorithm ("BOADICEA") for familial breast and ovarian cancer. This user-friendly web-based tool predicts the likelihood of carrying mutations in breast and ovarian cancer high-risk genes (BRCA1 and BRCA2), and the risks of developing breast or ovarian cancer. BOADICEA has been adopted by several national bodies including NICE in the UK (2006 until present), the American Cancer Society and the Ontario Breast Screening Program (both since 2011) for identifying women who would benefit from BRCA1/2 mutation screening, intensified breast cancer screening and chemoprevention.
Basic, clinical and applied research at the University of Cambridge has culminated in a widely-used risk prediction algorithm ("BOADICEA") for familial breast and ovarian cancer. This web-based, user-friendly tool predicts the likelihood of carrying mutations in breast and ovarian cancer high risk genes (BRCA1 and BRCA2), and the risk of developing breast or ovarian cancer. In 2006, BOADICEA was been recommended by the UK National Institutes of Health and Clinical Excellence (NICE: CG41, 2006) and the American Cancer Society (since 2011). In June 2013, NICE recommended BOADICEA in subsequent guidance (CG164). Furthermore, several national bodies have designated BOADICEA as the standard tool to assess eligibility for high risk breast cancer screening.
Scientists at The Institute of Cancer Research (ICR) have played a central role in analysing the RAS/RAF/MEK/ERK cell signalling pathway and defining targets for novel cancer therapeutics. Their research work was key in stimulating an international effort to develop MEK inhibitors. Subsequently, ICR scientists predicted that the BRAF protein would be a key node in this pathway and they made the significant discovery that mutant BRAF is an oncogene. This prompted an international search for BRAF inhibitors, which was facilitated by the ICR's structural biology studies of BRAF. As a result, two novel drugs are now on the market.
The PI3 kinase (PI3K) enzymes play a significant role in AKT-mTOR intracellular signalling, a key pathogenic pathway in many cancers. The ICR has discovered first-in-class inhibitors of class I PI3K and these are now being commercially developed by Genentech and are in clinical trials, having demonstrated clinical safety, as well as target inhibition and antitumour activity. To accelerate the commercial development of its PI3K inhibitors, the ICR founded the spin-out company Piramed Pharma, which was subsequently acquired by Roche for a total of $175million. The ICR's published research and its development of a tool compound has underpinned the worldwide effort by pharmaceutical companies to develop these novel cancer therapeutics.
Work by Professor Andrew Tutt at King's College London (KCL), has had the following major impacts: (i) it has provided proof through first-in-man clinical trials (in collaboration with the Royal Marsden/ICR Phase I Clinical Trials Unit) and Phase II clinical trials designed and led by Professor Tutt that poly(ADP ribose) polymerase (PARP) inhibitors have an anti-cancer action in breast and ovarian cancers with BRCA mutations; (ii) it has demonstrated that the concept of `synthetic lethality' can be applied to the selective targeting of cancer cells in humans; (iii) it has paved the way for a major programme of investment by the pharmaceutical industry (over $1 billion to date) in PARP inhibitors for the treatment of BRCA-related cancers (which are currently being tested in a range of cancers in Phase III trials); and (iv) it has been incorporated into UK, European, US and other international guidelines on genetic testing for breast and ovarian cancers that run in families.
The Institute of Cancer Research (ICR) conducted pioneering translational research into the use of aromatase inhibitors (AIs) in breast cancer. Novel assays were developed that enabled the effects of AIs to be measured accurately and facilitated their rapid entry into large scale clinical trials and subsequent widespread availability. The ICR showed how AIs should be used clinically and helped to establish international guidelines; in some indications AIs are now the accepted standard of care. Research at the ICR has also led to the evaluation and development of novel predictive tests to determine the prognosis of patients on these drugs.
Research at Queen's University Belfast has led to the successful development and commercialization of a DNA chip technology platform that facilitates the rapid discovery and validation of new diagnostic tests in cancer. A spin out company has been established called Almac Diagnostics that currently employs 85 staff, thereby significantly contributing to the knowledge based economy in Northern Ireland. Almac has used this technology to develop and validate a number of genomic tests that have been successfully licensed to established US based diagnostic companies, thereby securing long term revenue streams. Almac is now recognised internationally as a worldwide industry leader in this area.
Abiraterone (trade name Zytiga) was designed, synthesised and developed by a multidisciplinary team of academic chemists, biologists and clinicians at The Institute of Cancer Research (ICR). Following ICR-led phase I, II and III clinical trials, which demonstrated prolonged survival and improved quality of life for patients with castration-resistant prostate cancer (following cytotoxic therapy), abiraterone was granted approval by the FDA, EMA and NICE. In 2011-2012, abiraterone worldwide sales reached $2.755 billion. In 2012-13, FDA and EMA approval was extended to use in the treatment of metastatic castration-resistant prostate cancer in men who have not received standard chemotherapy.
University of Liverpool (UoL) research has characterised patients with pancreatitis at high risk of pancreatic cancer, defining strategies for their management now widespread globally. Clinical and genetic characterisation was conducted through the European Registry of Hereditary Pancreatitis and Familial Pancreas Cancer (EUROPAC), set up by the UoL in 1997 to pioneer secondary screening and trial appropriate management. As a result, it is now widely recommended that patients with a family history of pancreatitis should undergo genotyping and secondary screening, because of their risk of pancreatic cancer.
