Basilea reports start of first-in-human phase 1 oncology study with oral panRAF kinase inhibitor

BASEL, Switzerland, May 4, 2015 (GLOBE NEWSWIRE) -- Basilea Pharmaceutica Ltd. (SIX:BSLN) reported today the start of a clinical phase 1 study with the orally administered investigational drug BAL3833/CCT3833 in patients with advanced solid tumors. BAL3833/CCT3833 is the lead compound of a series of small molecule panRAF inhibitors recently in-licensed by Basilea.

The open-label dose-escalation phase 1 study is designed to investigate the safety and tolerability of once-daily oral doses of BAL3833/CCT3833 in adult patients with advanced solid tumors. The study aims to establish a safe maximum tolerated dose for future clinical studies.

"A significant range of cancers are associated with mutations in key factors involved in the transmission of growth signals, such as the RAF kinases, leading to uncontrolled tumor growth," said Dr. Laurenz Kellenberger, Basilea's Chief Scientific Officer. "The BRAF kinase, for example, is mutated in a range of cancers including 50% of melanomas. Preclinical data show that our novel panRAF kinase inhibitors are able to block growth of BRAF mutant melanoma cells in vitro and in vivo. This includes activity in tumor models resistant to currently marketed anti-cancer drugs targeting the BRAF pathway. Moreover, as these panRAF kinase inhibitors also target other growth modulators relied upon by drug-resistant tumor cells and non-melanoma cancers, it is anticipated that their spectrum of activity will extend beyond currently available BRAF inhibitors. This supports the potential for use of these panRAF inhibitors in the treatment of expanded melanoma patient populations as well as other cancer types."

Prof. Achim Kaufhold, Basilea's Chief Medical Officer, said: "The initiation of the first clinical study with this promising compound is a significant development milestone and we are very pleased to add BAL3833/CCT3833 as the second oncology drug in clinical stage to our expanding oncology development portfolio."

The study is sponsored by The Institute of Cancer Research, London, and The Royal Marsden NHS Foundation Trust and is being carried out at The Royal Marsden, and The Christie NHS Foundation Trust in Manchester, with biomarker work by the Cancer Research UK Manchester Institute at The University of Manchester and Basilea. The study will be funded by the Wellcome Trust, the NIHR Biomedical Research Centre at The Royal Marsden and The Institute of Cancer Research, The Christie charity and the Cancer Research UK Manchester Institute. Basilea will assume full operational responsibility after phase 1.

About BAL3833

BAL3833 (also known as CCT3833) is an orally available small-molecule panRAF kinase inhibitor targeting certain cell proliferation signaling pathways that are associated with tumor growth. It is the lead compound of a series of panRAF inhibitors recently in-licensed by Basilea under an agreement with The Institute of Cancer Research, London, Cancer Research Technology, the Wellcome Trust, and The University of Manchester. The compound originates from research at The Institute of Cancer Research and the Cancer Research UK Manchester Institute, by scientists funded by Cancer Research UK and the Wellcome Trust. These panRAF kinase inhibitors target both BRAF and the growth pathways that tumor cells rely on when they become resistant to existing drugs targeting BRAF. BRAF is mutated in a range of cancers including melanomas, colorectal and serous ovarian cancer. Data from preclinical studies suggest that compounds from this class are active in tumors derived from patients which have developed resistance to currently available RAF pathway inhibitors.[1]

About The Institute of Cancer Research, London

The Institute of Cancer Research, London, is one of the world's most influential cancer research institutes. Scientists and clinicians at The Institute of Cancer Research (ICR) are working every day to make a real impact on cancer patients' lives. Through its unique partnership with The Royal Marsden NHS Foundation Trust and "bench-to-bedside" approach, the ICR is able to create and deliver results in a way that other institutions cannot. Together the two organisations are rated in the top four cancer centres globally. The ICR has an outstanding record of achievement dating back more than 100 years. It provided the first convincing evidence that DNA damage is the basic cause of cancer, laying the foundation for the now universally accepted idea that cancer is a genetic disease. Today it leads the world at isolating cancer-related genes and discovering new targeted drugs for personalized cancer treatment. As a college of the University of London, the ICR provides postgraduate higher education of international distinction. It has charitable status and relies on support from partner organisations, charities and the general public. The ICR's mission is to make the discoveries that defeat cancer.
