FOR IMMEDIATE RELEASE
OncoMed’s Phase 2 Demcizumab Pancreatic Cancer Trial Misses Primary Endpoint
OncoMed Management to Host Conference Call/Webcast
at 8:30 a.m. ET/5:30 a.m. PT to Review Top-line Results
REDWOOD CITY, Calif., April 10, 2017 – OncoMed Pharmaceuticals, Inc. (Nasdaq: OMED), a clinical-stage biopharmaceutical company focused on discovering and developing novel anti-cancer stem cell and immuno-oncology therapeutics, today reported top-line results from the company’s Phase 2 YOSEMITE clinical trial of demcizumab (anti-DLL4, OMP-21M18) in combination with Abraxane® (paclitaxel protein-bound particles for injectable suspension) (albumin bound) plus gemcitabine in previously untreated patients with metastatic pancreatic cancer. The randomized Phase 2 “YOSEMITE” trial was designed to assess the efficacy and safety of demcizumab plus standard-of-care chemotherapy in first-line metastatic pancreatic cancer with the primary endpoint of progression-free survival and a secondary endpoint of overall survival. The trial did not meet the primary endpoint of progression-free survival. Additionally, the interim median overall survival analysis did not show a benefit for demcizumab in combination with Abraxane plus gemcitabine compared to the Abraxane, gemcitabine plus placebo arm in patients with first-line metastatic pancreatic cancer.
“Patients in all three arms of the Phase 2 YOSEMITE trial surpassed the published median overall survival rates for Abraxane plus gemcitabine in first-line metastatic pancreatic patients. While the interim median overall survival was 13.2 months in the pooled demcizumab arms, the interim median overall survival of Abraxane plus gemcitabine was not reached at the time of these analyses. Based on the lack of benefit over standard-of-care, which performed remarkably well, we will be discontinuing this trial. We will conduct additional analyses, together with our partner, Celgene, to understand these outcomes. We will also discontinue any additional enrollment in our other ongoing demcizumab trials and conduct analyses of the data from those trials as planned,” said Paul J. Hastings, Chairman and CEO of OncoMed Pharmaceuticals. “OncoMed remains focused on completing and analyzing the results of the two randomized Phase 2 clinical trials, PINNACLE and DENALI, that are anticipated in the first half of this year and in continuing the advancement of our portfolio of biotherapeutic candidates.”
OncoMed management will host a conference call today at 8:30 a.m. ET/5:30 a.m. PT to discuss the YOSEMITE clinical trial data.
Summary of Key Findings
• |
Progression-Free Survival: The median progression-free survival (mPFS) was essentially the same across all arms of the study. For patients receiving demcizumab (either one or two truncated courses) in combination with Abraxane plus gemcitabine the mPFS was 5.5 months compared to a mPFS of 5.5 months for those in the Abraxane, gemcitabine plus placebo group (HR=0.93). In addition, no significant differences were observed when the individual treatment arms were compared to the Abraxane, gemcitabine plus placebo arm: in patients receiving a single truncated course of demcizumab the mPFS was 5.4 months (HR=1.03), and the mPFS was 5.5 months (HR=0.83) in patients receiving two truncated courses of demcizumab. |

months was seen among patients receiving two courses of demcizumab (n=65) (HR=0.87). These results are based on an analysis that occurred at the 125th PFS event at which time there were 75 deaths. |
• |
Response and Clinical Benefit Rates: Overall response rate (defined as complete responses and partial responses) was 33.1% (45 of 136 patients) in the combined demcizumab, Abraxane plus gemcitabine groups and 41.2% (28 of 68 patients) in the Abraxane, gemcitabine plus placebo group. The overall clinical benefit rate (defined as complete responses, partial responses and stable disease) was slightly higher in the pooled demcizumab arms at 74.3% (101 of 136 patients) compared to 70.6% (48 of 68 patients) in the Abraxane, gemcitabine plus placebo group. Response was measured using the RECIST 1.1 criteria and is based on unconfirmed investigator assessment. |
• |
Safety and tolerability: Demcizumab, Abraxane plus gemcitabine were generally well tolerated with nausea, diarrhea, anemia and fatigue being the most common reported toxicities. The incidence of Grade 3 or greater heart failure, pulmonary hypertension and bleeding were (3.7% vs. 0%), (0.7% vs 0%) and (8.1% vs. 1.5%) in the pooled demcizumab, Abraxane plus gemcitabine arms and the Abraxane, gemcitabine plus placebo arm, respectively. |
“Pancreatic cancer has proven to be a uniquely challenging disease, and these data appear to reflect some of those disease and treatment complexities. The safety data seen in the YOSEMITE trial were generally consistent and in line with our expectations. We continue to analyze these data, and look forward to presenting the full study findings at a future scientific congress,” said Robert Stagg, PharmD, Senior Vice President of Clinical Research and Development. “We would like to sincerely thank the patients and their families, investigators and staff for their support and participation in this study.”
About the Phase 2 YOSEMITE Trial
The randomized Phase 2 “YOSEMITE” trial was designed to assess the efficacy and safety of demcizumab in combination with Abraxane plus gemcitabine, compared to Abraxane, gemcitabine plus placebo in first-line pancreatic cancer patients with metastatic disease. Two-hundred and seven patients were randomized and 204 patients were treated in one of three study arms: 1) Abraxane, gemcitabine plus placebo, 2) Abraxane, gemcitabine plus one 70-day truncated course of demcizumab (given once every 2 weeks with the last dose given on Day 70) or 3) Abraxane, gemcitabine plus two 70-day truncated courses of demcizumab (separated by a 98 day period without demcizumab) with the last demcizumab dose given on day 238.
The primary endpoint of YOSEMITE was progression-free survival. Secondary and exploratory endpoints were overall survival, response rate, pharmacokinetics, immunogenicity, safety and biomarker analyses. The YOSEMITE Phase 2 trial was conducted at 49 clinical sites in the U.S., Canada, Europe and Australia. OncoMed initiated YOSEMITE in April 2015 and completed enrollment of patients in September 2016.

About Pancreatic Cancer
Pancreatic cancer is the third leading cause of cancer-related deaths. According to the American Cancer Society, each year in the United States there are approximately 54,000 new cases of pancreatic cancer and 43,000 deaths. The majority of patients with pancreatic cancer are diagnosed after their cancer has spread locally and/or metastasized to distant organs. The average life expectancy after the diagnosis of metastatic pancreatic cancer is less than one year.

Demcizumab is a humanized monoclonal antibody targeting Delta-like Ligand 4 (DLL4), a key member of the Notch signaling pathway. Based on preclinical studies, demcizumab may have a multi-pronged mechanism of action: halting cancer stem cell growth and reducing cancer stem cell frequency, disrupting angiogenesis in the tumor and augmenting anti-tumor immune responses by decreasing tumor myeloid-derived suppressor cells (MDSCs).
Demcizumab is currently being studied in two randomized Phase 2 clinical trials. The YOSEMITE trial is testing demcizumab with Abraxane plus gemcitabine versus Abraxane plus gemcitabine alone in first-line advanced pancreatic cancer patients. The DENALI trial is testing demcizumab with pemetrexed and carboplatin versus pemetrexed and carboplatin alone in first-line advanced non-small cell lung cancer patients. A Phase 1b trial combining demcizumab with the anti-PD1 antibody pembrolizumab in solid tumor patients was also initiated in early 2016. Demcizumab is part of OncoMed's collaboration with Celgene Corporation.

OncoMed Pharmaceuticals Announces Bayer Terminates its Option to License Vantictumab or Ipafricept
OncoMed Retains Worldwide Rights to Both Wnt Pathway Programs
Redwood City, CA, – April 10, 2017 – OncoMed Pharmaceuticals, Inc. (XNAS: OMED), a clinical-stage biopharmaceutical company focused on discovering and developing novel anti-cancer stem cell and immuno-oncology therapeutics, announced today that Bayer Pharma has notified OncoMed of its decision not to exercise its option to license the first-in-class Wnt pathway inhibitors vantictumab (anti-Fzd, OMP-18R5) and ipafricept (Fzd8-Fc, OMP-54F28) for strategic reasons. Effective June 2017, OncoMed will retain worldwide development and commercialization rights to vantictumab, ipafricept and all other Wnt pathway biologics under the collaboration. The small molecule program under the companies’ collaboration continues without change.
“Under our collaboration with Bayer, we have received over $90 million in upfront and milestone payments that have fully funded the development of vantictumab and ipafricept. While we had looked forward to collaborating with the Bayer team on the late-stage development of these biotherapeutics, we are very pleased to have worldwide rights to two promising Phase 2-ready assets,” said Paul J. Hastings, Chairman and CEO of OncoMed. “We will be conducting an internal portfolio review and prioritization as we determine next steps for all our programs, including vantictumab and ipafricept.
Vantictumab and ipafricept are selective inhibitors of the Wnt pathway. In Phase 1a and Phase 1b clinical trials, vantictumab and ipafricept have each demonstrated safety and tolerability alone and in combination with standard-of-care chemotherapies in several solid tumors.. The company is completing two Phase 1b combination clinical trials of vantictumab – one in HER2-negative breast cancer (vantictumab + paclitaxel) and one in advanced pancreatic cancer (vantictumab + gemcitabine + Abraxane®) – and two Phase 1b combination clinical trials of ipafricept – one in ovarian cancer (ipafricept + carboplatin + paclitaxel) and one in pancreatic cancer (ipafricept + gemcitabine + Abraxane®). Interim data presented from each of these trials during the 2016 ASCO Annual Meeting and the ESMO 2016 Congress showed early indications of anti-tumor activity. In preclinical studies, OncoMed researchers have observed evidence of synergies when these Wnt inhibitor compounds are administered sequentially following the use of taxane-based chemotherapies. Published preclinical studies also point to the Wnt pathway as being a possible potentiator of immune response in tumors.
