Protein kinase B (PKB), also known as AKT, is an enzyme in the PI3 kinase/mTOR intracellular signalling pathway, which is found to be deregulated in many forms of cancer. Professor David Barford's team at the ICR solved the crystal structure of PKB03b2 using innovative protein engineering and licensed six international pharmaceutical companies with reagents to enable them to begin PKB drug discovery programmes. The ICR also initiated its own PKB drug discovery programme: two series of inhibitors were developed that were licensed to AstraZeneca and Astex and are now both in clinical trial. The ICR's work helped to establish PKB as a valid cancer therapeutic target. The ICR is involved in clinical research studies of multiple PI3 kinase and PKB inhibitors, and this research has led to the definition of useful clinical pharmacodynamic biomarkers.
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.
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.
PKB (protein kinase B), also known as AKT, is an enzyme in the PI3 kinase/mTOR intracellular signalling pathway, which is deregulated in many cancers. Professor David Barford's team at the ICR solved the crystal structure of PKB03b2 using innovative protein engineering. The ICR has licensed six international pharmaceutical companies with reagents to enable them to begin PKB drug discovery programmes. The Barford team has also used their structural biology expertise to advance the ICR's own PKB inhibitor drug discovery programme. Two series of inhibitors were developed that were licensed to AstraZeneca and Astex and are now both in clinical trials.
The Institute of Cancer Research (ICR) has made seminal contributions to the development and dissemination of conformal radiotherapy and intensity modulated radiotherapy (IMRT), leading to changes in clinical practice, reduced treatment complications and improved cure rates. ICR researchers developed conformal radiotherapy, which allowed better shaping of the high-dose radiation volume around a tumour, and they then refined this technique to create IMRT, which makes possible the definition of a high dose volume with a concave border allowing further sparing of critical normal tissue. IMRT is now the approved treatment regime for many cancers such as prostate, breast and head and neck in the USA, the UK and many European countries.
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.
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.
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.
The ICR has a world-leading role in identifying, characterising and clinically exploiting genetic factors that predispose to cancer. This has had a direct and significant impact on public health and patient care; over 250,000 clinical tests for gene modifications that were identified at ICR are performed annually worldwide. Many thousands of families have benefited through optimised treatments for individuals with cancer and improved cancer risk estimation, targeted screening and risk-reducing measures for their relatives. Cancer genes discovered at the ICR include breast cancer genes (BRCA2, CHEK2, BRIP1, PALB2), ovarian cancer genes, (BRCA2, RAD51D, PPM1D), a renal cancer gene (FH) and childhood cancer genes (BUB1B, PALB2, EZH2).
The Institute of Cancer Research (ICR) founded the spin out company Domainex in 2002 in collaboration with UCL and Birkbeck. The company was set up on the basis of novel research into the expression of soluble protein domains to provide services to a range of bioscience-based companies. Within the period 2008-2013, Domainex has established profitability and positioned itself as a successful company employing over 30 scientists at its laboratories in Cambridge. It has established programmes and contracts with over 20 international clients in medicinal chemistry, drug discovery, monoclonal antibody development and agrochemical science, making a major commercial impact in all these fields.
