MMRF PRESS RELEASES
Sunesis Pharmaceuticals and the Multiple Myeloma Research Consortium Form Collaboration to Study SNS-032 in Multiple Myeloma
South San Francisco, CA — December 19, 2007
Sunesis Pharmaceuticals, Inc. (Nasdaq: SNSS) and the Multiple Myeloma Research Consortium (MMRC) have entered into a collaboration to evaluate Sunesis' SNS-032 as a potential therapeutic for the treatment of multiple myeloma.
The MMRC collaboration is evaluating the preclinical activity of SNS-032 in multiple myeloma-relevant models and in primary disease tissue, extending non-clinical studies performed by Sunesis. Under the lead of Suzanne Trudel, MSc, M.D., Assistant Professor, Princess Margaret Hospital, University Health Network, these studies are also being conducted at four other MMRC-affiliated institutions: Dana-Farber Cancer Institute, H. Lee Moffitt Cancer Center & Research Institute, Mayo Clinic Cancer Center and Emory University. Data from these studies will facilitate the identification of relevant mechanism-based biomarkers of patient response to SNS-032 and may guide rational combination strategies in planned clinical trials of SNS-032 in multiple myeloma.
"We are excited to be working with the MMRC and world-renowned researchers in further elucidating the potential of SNS-032 for the treatment of multiple myeloma," said Daniel C. Adelman, M.D., Sunesis' Senior Vice President, Development and Chief Medical Officer. "This collaboration is providing us with access to cutting-edge disease models, and the resulting data should further define SNS-032's mechanism of action and the compound's potential benefits in this patient population. Importantly, the additional data gathered by these thought leaders will supplement our own research and allow us to optimize our clinical trial programs. Sunesis is currently conducting a Phase 1 clinical trial of SNS-032 in patients with multiple myeloma and chronic lymphocytic leukemia."
"There is an acute need to develop new, targeted therapies capable of attacking the underlying mechanisms responsible for making multiple myeloma so difficult to treat," said Kathy Giusti, Founder and Chief Executive Officer of the MMRC. "We are pleased to be working with Sunesis to advance research on SNS-032, which appears to be potentially well suited to the treatment of multiple myeloma and other B-cell malignancies. The MMRC is committed to conducting collaborations of this sort with industry to bring better, more effective treatments to myeloma patients as quickly as possible."
SNS-032 is a potent, selective inhibitor of cyclin-dependent kinases (CDKs) 2, 7 and 9 that inhibits both cell cycle progression and transcription. SNS-032 has been shown in preclinical and clinical studies to deplete cells of key survival factors, including myeloid cell leukemia sequence 1, or MCL-1, a protein associated with cell survival, particularly in B-cell malignancies such as multiple myeloma. It is hypothesized that down regulation of survival proteins will provide clinical benefit in hematologic cancers by inducing apoptosis of malignant cells and disrupting tumor-stromal interactions requisite for maintaining these diseases.
About the Multiple Myeloma Research Consortium (MMRC)
The Multiple Myeloma Research Consortium (MMRC) is a 509a3 non-profit organization that integrates leading academic institutions to accelerate drug development in multiple myeloma. It is comprised of the MMRC and 13 member institutions: City of Hope Cancer Center, Dana-Farber Cancer Institute, Emory University's Winship Cancer Institute, Hackensack University Medical Center, H. Lee Moffitt Cancer Center & Research Institute, Mayo Clinic, Ohio State University, Roswell Park Cancer Institute, St. Vincent's Comprehensive Cancer Center of Saint Vincent Catholic Medical Centers of New York, University Health Network (Princess Margaret Hospital), University of Chicago, University of Michigan, and Washington University.
The MMRC was founded in 2004 by Kathy Giusti, a myeloma patient, and with the help of the scientific community, as an optimal research model to rapidly address critical challenges in accelerating drug development and explore opportunities in the most promising areas of myeloma research – genomics, compound validation, and clinical trials. The MMRC is the only consortium to join academic institutions through membership agreements, customized IT systems, and an integrated tissue bank. For more information, please visit www.themmrc.org.
