OncoMed’s Phase 2 Trial of Tarextumab in Small Cell Lung Cancer
Does Not Meet Endpoints

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 17, 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 randomized 145-patient Phase 2 PINNACLE clinical trial of tarextumab (anti-Notch2/3, OMP-59R5) in combination with etoposide plus either cisplatin or carboplatin chemotherapy (“chemotherapy”) in previously untreated patients with extensive-stage small cell lung cancer. Results for the combination of tarextumab plus chemotherapy were undifferentiated from those of chemotherapy plus placebo, and therefore the trial did not meet its primary endpoint of progression-free survival or secondary endpoints of overall survival and biomarkers reflective of Notch pathway gene activation.
“Small cell lung cancer is a very difficult-to-treat disease and unfortunately, tarextumab did not show benefit over placebo in this Phase 2 trial,” said Paul J. Hastings, OncoMed’s Chairman and CEO. “We deeply appreciate the participation by the investigators and staff, patients and caregivers who all contributed to the conduct and completion of this Phase 2 clinical trial.”
OncoMed also announced today that it will discontinue enrollment in the Phase 1b clinical trial of brontictuzumab (anti-Notch1, OMP-52M51) in combination with trifluridine/tipiracil (Lonsurf®) in third-line colorectal cancer patients. The combination of brontictuzumab plus chemotherapy was not tolerable in this patient population.
“Based on the events of today and last week, we will be undertaking a comprehensive portfolio prioritization review immediately,” continued Mr. Hastings. “The immediate task ahead is to thoroughly examine the available data, our resources and the opportunities to re-focus our efforts. We ended the first quarter of 2017 with $156.9 million in cash and short-term investments.”
The median progression-free survival (mPFS) for tarextumab plus chemotherapy was 5.6 months versus 5.5 months for chemotherapy plus placebo (HR=0.969). The median overall survival (mOS) analysis did not show a benefit for tarextumab in combination with chemotherapy (mOS=9.3 months) compared to the chemotherapy plus placebo arm (10.3 months; HR=1.01). Five individual Notch biomarkers (Hes1, Hes6, Hey1, Hey2 and Notch3) failed to identify a definitive subset of patients with a treatment effect on either mPFS or mOS. Overall response rates were 68.5% and 70.8% in the tarextumab and placebo arms respectively. The combination of tarextumab plus chemotherapy was well tolerated. The safety profile appeared to be similar between the two groups except for diarrhea and thrombocytopenia, which were more prevalent in the tarextumab treatment arm, and constipation, which was more prevalent in the placebo arm.
OncoMed management will host a conference call today at 8:30 a.m. ET/5:30 a.m. PT to discuss the PINNACLE clinical trial data. OncoMed plans to present full study findings, including results from the biomarker analyses, at a future scientific conference.

Patients enrolled in the randomized, double-blinded, multi-center PINNACLE clinical trial were randomized into two study arms and received either 15mg/kg of tarextumab every three weeks in combination with six cycles of etoposide and either cisplatin or carboplatin chemotherapy followed by tarextumab maintenance to progression or six cycles of chemotherapy and a placebo. The primary endpoint of the trial was progression-free survival. Secondary endpoints included overall survival and overall response rate, pharmacokinetics, safety and biomarker analyses. Overall survival, progression-free survival and overall response rates are also being assessed against elevated tumor expression of the Notch pathway genes Hes1, Hes6, Hey1, Hey2 and Notch3 as a secondary endpoint. The PINNACLE trial was conducted at 36 sites in the United States.

About Tarextumab (anti-Notch2/3, OMP-59R5)
Tarextumab (anti-Notch2/3, OMP-59R5) is a fully human monoclonal antibody that targets the Notch2 and Notch3 receptors. Preclinical studies suggested that tarextumab exhibits two mechanisms of action: (1) by downregulating Notch pathway signaling, tarextumab appears to have anti-cancer stem cell effects, and (2) tarextumab affects pericytes, impacting stromal and tumor microenvironment. Tarextumab is part of OncoMed's collaboration with GlaxoSmithKline (GSK).
About Small Cell Lung Cancer
According to the American Cancer Society, lung cancer (both small cell and non-small cell) is the second most common cancer in men and women and is by far the leading cause of cancer death. Small cell lung cancer is expected to make up about 10%-15% of the 224,390 newly diagnosed lung cancer cases and the 158,080 deaths estimated to occur in the U.S. in 2016. Small cell lung cancer tends to grow and spread quickly, and is typically not discovered until it has metastasized to other parts of the body (extensive stage). The current standard of care in treating small cell lung cancer is the chemotherapeutic etoposide in combination with either cisplatin or carboplatin. In spite of a high sensitivity to chemotherapy and remission rates of up to 80% following initial treatment, the median overall survival is less than one year for patients with extensive stage disease1.
