Updated clinical data to be presented for vantictumab at ECC 2013
Vantictumab, a program partnered with Bayer Pharma AG, is advancing to three combination Phase 1b studies in selected tumor types
REDWOOD CITY, Calif., Sept. 23, 2013 (GLOBE NEWSWIRE) -- OncoMed Pharmaceuticals, Inc. (Nasdaq:OMED), a clinical-stage company developing novel therapeutics that target cancer stem cells (CSCs), or tumor-initiating cells, today reported that new data for vantictumab, a monoclonal antibody targeting the WNT pathway, will be presented at a poster session at the Joint ECCO 17, 38th ESMO and 32nd ESTRO European Cancer Congress 2013 (ECC 2013) in Amsterdam, The Netherlands.
The poster presentation called "A phase I study in patients with advanced solid tumors for the human monoclonal antibody vantictumab (OMP-18R5; anti-Frizzled) targeting the WNT pathway" will be presented in the Poster Session "Drug Development" on Sunday, September 29, 2013 from 09:30 to 12:00 CET. The presenting author is Dr. David Smith from the University of Michigan Cancer Center at Ann Arbor, MI, on behalf of the other principal investigators Dr. Lee Rosen at the University of California, Los Angeles, CA, Dr. Kyriakos Papadopoulos at The START Center for Cancer Care, San Antonio, TX and the entire study team.
Vantictumab is a first-in-class monoclonal antibody that has broad anti-cancer stem cell and anti-tumor activity in patient-derived xenograft tumor models. In the ongoing Phase 1a trial, vantictumab is well tolerated in advanced solid tumor patients. Vantictumab shows pharmacodynamic effects on the WNT pathway in patient samples. OncoMed is planning to initiate Phase 1b trials in three tumor indications to study its safety in combination with standard-of-care chemotherapy. Vantictumab is part of OncoMed's Wnt pathway collaboration with Bayer Pharma AG.
Paul Hastings, Chairman and Chief Executive Officer of OncoMed noted, "We have made excellent progress with vantictumab and our other clinical program targeting the WNT pathway, Fzd8-Fc (also known as OMP-54F28). We look forward to presenting the updated data for vantictumab in advanced solid tumor patients at the European Cancer Congress 2013 in Amsterdam."
About Vantictumab (OMP-18R5)
Vantictumab is a first-in-class antibody that has shown broad anti-CSC and anti-tumor activity in patient-derived xenograft tumor models. Vantictumab inhibits a key signaling pathway in cancer, the Wnt pathway. Specifically, vantictumab selectively targets Frizzled receptors, which are activators of Wnt signaling. Although vantictumab was originally identified by binding to Frizzled7, the antibody selectively targets five different Frizzled receptors. Vantictumab is currently in Phase 1. Vantictumab is part of OncoMed's collaboration with Bayer Pharma AG.
About Cancer Stem Cells
Cancer stem cells, or CSCs, are the subpopulation of cells in a tumor responsible for driving growth and metastasis of the tumor. CSCs, also known as tumor-initiating cells, exhibit certain properties which include the capacity to divide and give rise to new CSCs via a process called self-renewal and the capacity to differentiate or change into the other cells that form the bulk of the tumor. Common cancer drugs target bulk tumor cells but have limited impact on CSCs, thereby providing a path for recurrence of the tumor. OncoMed's product candidates target CSCs by blocking self-renewal and driving differentiation of CSCs toward a non-tumorigenic state, and also impact bulk tumor cells. OncoMed believes its product candidates are distinct from the current generations of chemotherapies and targeted therapies, and have the potential to significantly impact cancer treatment and the clinical outcome of patients with cancer.
About OncoMed Pharmaceuticals
OncoMed Pharmaceuticals is a clinical-stage company focused on discovering and developing novel therapeutics targeting cancer stem cells. OncoMed has five anti-cancer product candidates in clinical development, including demcizumab (Anti-DLL4, OMP-21M18), OMP-59R5 (Anti-Notch2/3), OMP-52M51 (Anti-Notch1), vantictumab (Anti-FZD7, OMP-18R5) and OMP-54F28 (Fzd8-Fc), which target key cancer stem cell signaling pathways including Notch and Wnt. OncoMed has two other antibodies in preclinical development with Investigational New Drug filings planned for as early as 2014. OncoMed is also pursuing discovery of additional novel anti-CSC product candidates. OncoMed has formed strategic alliances with Bayer Pharma AG and GlaxoSmithKline (GSK).
