REDWOOD CITY, CA, USA I August 28, 2014 I OncoMed Pharmaceuticals, Inc. (OMED), announced today that the U.S. Food and Drug Administration (FDA) has removed the partial clinical hold on enrollment in the company’s vantictumab (anti-Fzd7, OMP-18R5) Phase 1 clinical trials. Vantictumab is being studied in combination with standard-of-care chemotherapy in three Phase 1b clinical trials in patients with advanced non-small cell lung cancer (NSCLC), advanced HER2-negative breast cancer and advanced pancreatic cancer. Enrollment and dosing of new patients is expected to resume within the next few weeks as the study sites’ institutional review boards (IRBs) receive and approve the revised trial protocols.
“We are pleased by the FDA’s action to allow the resumption of enrollment in the vantictumab clinical trials,” said Jakob Dupont, MD, OncoMed’s Chief Medical Officer. “Patient safety is our top priority. The revised protocols were developed with input from the vantictumab clinical investigators and academic bone experts and are intended to mitigate the risks of future adverse events as we seek an optimal efficacious dose to take forward in the development of this first-in-class WNT pathway inhibitor.”
The partial clinical hold occurred on July 1, 2014 following the company’s voluntary halt to its Wnt pathway programs due to observed on-target mild-to-moderate bone-related adverse events. The FDA removed the partial clinical hold to permit the enrollment of vantictumab clinical trials following its review of a substantial clinical safety and efficacy data package and revised study protocols submitted by the company. The amendments for the Phase 1b combination trials include modified dosing regimens, risk mitigation measures, such as increased monitoring and bone protection strategies, and modified enrollment criteria.
“The diligence and dedication of OncoMed’s clinical development team to temporarily halt the vantictumab studies and submit a comprehensive response to the FDA has led to a prompt action by the agency,” said Paul J. Hastings, Chairman and Chief Executive Officer of OncoMed. “We look forward to proceeding with the vantictumab Phase 1b clinical studies, and to the potential opt in by our partner Bayer based on data from these trials, to realize the future potential of this novel first-in-class WNT pathway inhibitor.”
About Vantictumab (anti-Fzd7, OMP-18R5)
Vantictumab is a first-in-class antibody that has shown broad anti-cancer stem cell 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. OncoMed is currently completing a Phase 1a study of vantictumab in patients with advanced solid tumors. Preliminary data from this clinical trial were presented at the European Cancer Conference (ECC 2013) in September 2013 in Amsterdam, NL. Biomarker data for this Phase 1a trial were presented at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics in Boston, MA, in October 2013. Vantictumab is now being tested in combination with standard-of-care chemotherapy in three Phase 1b clinical trials in: 1) advanced NSCLC (vantictumab + docetaxel); 2) advanced HER2-negative breast cancer (vantictumab + paclitaxel); and 3) advanced pancreatic cancer (vantictumab + gemcitabine + Abraxane(R)). Vantictumab is part of OncoMed’s collaboration with Bayer Pharma AG.
About OncoMed Pharmaceuticals
OncoMed Pharmaceuticals is a clinical-stage company focused on discovering and developing novel therapeutics targeting cancer stem cells (CSCs). OncoMed has five anti-cancer product candidates in clinical development, including demcizumab (anti-DLL4, OMP-21M18), tarextumab (anti-Notch2/3, OMP-59R5), anti-Notch1 (OMP-52M51), vantictumab (anti-FZD7, OMP-18R5), and ipafricept (FZD8-Fc, OMP-54F28), which target key cancer stem cell signaling pathways including Notch and Wnt. OncoMed has two other antibodies in preclinical development, anti-DLL4/anti-VEGF bispecific (OMP-305B83) and anti-RSPO3 (OMP-131R10), with Investigational New Drug filings planned for late 2014 or early 2015. OncoMed is also pursuing discovery of additional novel anti-CSC and cancer immunotherapy product candidates. OncoMed has formed strategic alliances with Celgene Corporation, Bayer Pharma AG and GlaxoSmithKline (GSK). Additional information can be found at the company’s website: www.oncomed.com.
