The YOSEMITE trial was designed to assess the efficacy and safety of demcizumab in combination with Abraxane (paclitaxel protein-bound particles for injectable suspension) (albumin bound) plus gemcitabine (standard of care) compared to standard of care alone. The Phase 2 dose of demcizumab was 3.5 mg/kg every two weeks for up to 70 days. The primary endpoint of YOSEMITE is progression-free survival. Secondary and exploratory endpoints include overall survival, response rate, pharmacokinetics, immunogenicity, safety and biomarker analyses. Patients enrolled in the YOSEMITE Phase 2 were randomized into one of three study arms receiving 1) standard of care plus one course of demcizumab, 2) standard of care plus demcizumab followed by a second course of demcizumab after a 98-day wash-out period or 3) standard of care plus placebo. The YOSEMITE Phase 2 trial was conducted at 49 clinical sites in the U.S., Europe and Australia. OncoMed initiated YOSEMITE in April 2015.

"We would like to thank the patients and their caregivers as well as the investigators and study teams for their participation and support in this trial," said Jakob Dupont, M.D., Chief Medical Officer of OncoMed. "Improving outcomes for patients with metastatic pancreatic cancer has proven to be highly challenging and the need for additional treatment options is of great importance. In Phase 1b studies, demcizumab combined with standard of care demonstrated promising response rates and survival trends, and we look forward to gaining further insights into demcizumab’s potential in pancreatic cancer from the Phase 2 YOSEMITE trial."

In OncoMed’s Phase 1b clinical trial of demcizumab truncated dosing and Abraxane plus gemcitabine, 14 of 28 (50%) patients evaluable for response achieved partial responses (unconfirmed) and another 11 (39%) achieved stable disease. Among 32 patients evaluable for survival in the Phase 1b, median progression-free survival was 7.1 months and median overall survival was 12.7 months for the patients who received one truncated 70-day course of demcizumab with Abraxane plus gemcitabine. The combination of demcizumab and Abraxane plus gemcitabine was generally well tolerated with fatigue, nausea and vomiting being the most common drug related toxicities. Final results from OncoMed’s Phase 1b trial of demcizumab were presented at the 2016 Gastrointestinal Cancers Symposium.

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 49,000 new cases of pancreatic cancer and 41,000 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.

About Demcizumab (anti-DLL4, OMP-21M18)
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 appears to 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.

On September 1, 2016 Array BioPharma (Nasdaq: ARRY) reported that the FDA has accepted its New Drug Application (NDA) for binimetinib with a target action date under the Prescription Drug User Fee Act (PDUFA) of June 30, 2017 (Press release, Array BioPharma, SEP 1, 2016, View Source [SID:1234514864]). Array completed its NDA submission of binimetinib in late June 2016 based on findings from the pivotal Phase 3 NEMO (NRAS MELANOMA AND MEK INHIBITOR) trial in patients with NRAS-mutant melanoma. The FDA also indicated that it plans to hold an advisory committee meeting (ODAC) as part of the review process. As previously reported, Array is currently preparing for an Application Orientation Meeting (AOM) with the FDA in September 2016, which it expects will include a discussion of the NDA package including clinical risk / benefit.

"There are very few treatment advances beyond immunotherapy for this devastating disease, which impacts one out of five advanced melanoma patients," said Victor Sandor, M.D., Chief Medical Officer, Array BioPharma. "Binimetinib is the first and only MEK inhibitor to demonstrate improvement on progression free survival in a Phase 3 trial for NRAS mutant melanoma patients."

About the Phase 3 NEMO Study

The NEMO trial, (NCT01763164), is an international, randomized Phase 3 study evaluating the safety and efficacy of 45 mg BID binimetinib, compared to 1,000 mg/m2 dacarbazine dosed every three weeks. Prior immunotherapy treatment was allowed, and patients underwent radiographic assessment of disease status every six weeks. Assessment of progression was determined by blinded central review. Over 100 sites across North America, Europe, South America, Asia and Australia participated in the study.

Results from the NEMO trial were presented at the 2016 ASCO (Free ASCO Whitepaper) Annual Meeting. The study met its primary endpoint of improving progression-free survival (PFS) compared with dacarbazine treatment. The median PFS on the binimetinib arm was 2.8 months, versus 1.5 months on the dacarbazine arm. In the pre-specified subset of patients who received prior treatment with immunotherapy, including ipilimumab, nivolumab or pembrolizumab, patients who received binimetinib experienced 5.5 months of median PFS, compared with 1.6 months for those receiving treatment with dacarbazine. While the results in the pre-specified sub-group of patients who had received prior treatment with immunotherapy are of interest, interpretation beyond overall consistency with the primary result should be made with care. Array anticipates that the primary consideration for marketing approval will be the results for the primary endpoint of the trial. In addition to improving PFS, binimetinib also demonstrated improvement in overall response rate (ORR) and disease control rate. While there was no statistically significant difference demonstrated in overall survival (OS), the median overall survival (mOS) favored the binimetinib arm. Under the NEMO protocol, and in accordance with accepted statistical practice, the subgroup analyses of OS are formally conducted only if the key secondary endpoint of OS reached statistical significance. Binimetinib was generally well-tolerated and the adverse events reported were consistent with previous results in NRAS-mutant melanoma patients.

Binimetinib is an investigational medicine and is not currently approved in any country.

About NRAS-Mutant Melanoma
Melanoma is the fifth most common cancer among men and the seventh most common cancer among women in the United States, with more than 76,000 new cases and nearly 10,000 deaths from the disease projected in 2016. Activating NRAS mutations are present in up to 20 percent of patients with metastatic melanoma, and is a poor prognostic indicator for these patients. Treatment options for this population remain limited beyond immunotherapy, and patients face poor clinical outcomes and high mortality.

About Binimetinib
MEK and BRAF are key protein kinases in the MAPK signaling pathway (RAS-RAF-MEK-ERK). Research has shown this pathway regulates several key cellular activities including proliferation, differentiation, survival and angiogenesis. Inappropriate activation of proteins in this pathway has been shown to occur in many cancers, such as melanoma, colorectal and thyroid cancers. Binimetinib is a late-stage small molecule MEK inhibitor, which targets key enzymes in this pathway.

Binimetinib is currently being studied in several other oncology trials, including the Phase 3 COLUMBUS trial studying encorafenib in combination with binimetinib in patients with BRAF-mutant melanoma and the recently initiated BEACON trial that will study encorafenib in combination with binimetinib and cetuximab in patients with BRAF V600E-mutant colorectal cancer. Array projects COLUMBUS top-line results availability during the third quarter of 2016.

On September 1, 2016 Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), reported positive results for TECENTRIQ from the Phase III study, OAK (Press release, Genentech, SEP 1, 2016, View Source [SID:1234514850]). The study met its co-primary endpoints and showed a statistically significant and clinically meaningful improvement in overall survival (OS) compared with docetaxel chemotherapy in people with locally advanced or metastatic non-small cell lung cancer (NSCLC) whose disease progressed on or after treatment with platinum-based chemotherapy. Adverse events were consistent with what has been previously observed for TECENTRIQ. Genentech looks forward to presenting full results at an upcoming medical meeting in 2016.

"These results add to the growing body of evidence that supports the role of TECENTRIQ as a potential new treatment for specific types of advanced NSCLC," said Sandra Horning, M.D., chief medical officer and head of Global Product Development. "This is very encouraging news for people living with this disease because lung cancer is the leading cause of cancer deaths around the world. We hope to bring this treatment option to patients as soon as possible."

The FDA granted Breakthrough Therapy Designation (BTD) for TECENTRIQ for the treatment of people with PD-L1 (programmed death-ligand 1) positive NSCLC whose disease has progressed during or after platinum-based chemotherapy (and appropriate targeted therapy for those with an EGFR mutation-positive or ALK-positive tumor). Genentech’s Biologics License Application (BLA) for NSCLC was granted Priority Review with an action date of Oct. 19, 2016.

Genentech has eight Phase III lung studies underway evaluating TECENTRIQ alone or in combination with other treatments in people with early and advanced stages of lung cancer.

About the OAK study

OAK is a Phase III, global, multicenter, open-label, randomized, controlled study evaluating the efficacy and safety of TECENTRIQ compared with docetaxel in people with locally advanced or metastatic NSCLC whose disease progressed on or after treatment with platinum-containing chemotherapy.

The study’s co-primary endpoints were overall survival in:
All people randomized to treatment in the study (intention-to-treat or ITT population), and
a PD-L1 selected subgroup of people
PD-L1 expression was assessed on both tumor cells (TC) and tumor-infiltrating cells (IC) with an investigational immunohistochemistry (IHC) test based on the SP142 antibody being developed by Roche Tissue Diagnostics, and was defined as people whose tumors were determined to express PD-L1 with an IHC score of TC1/2/3 or IC1/2/3.
Secondary endpoints included objective response rate (ORR), progression-free survival (PFS), duration of response (DOR) and safety.
A total of 1,225 patients were enrolled and randomized 1:1 to receive either docetaxel (75 mg/m2 intravenous infusion) or TECENTRIQ (1200 mg intravenous infusion) every three weeks. Treatment on TECENTRIQ continued as long as patients experienced clinical benefit as assessed by the investigator or until unacceptable toxicity. The primary efficacy analysis was based on the first 850 randomized patients, and the secondary efficacy analysis will include all 1,225 randomized patients.

About non-small cell lung cancer

According to the American Cancer Society, it is estimated that more than 224,000 Americans will be diagnosed with lung cancer in 2016, and NSCLC accounts for 85 percent of all lung cancers. It is estimated that approximately 60 percent of lung cancer diagnoses in the United States are made when the disease is in the advanced stages.

About TECENTRIQ (atezolizumab)

TECENTRIQ is a monoclonal antibody designed to bind with a protein called PD-L1. TECENTRIQ is designed to bind to PD-L1 expressed on tumor cells and tumor-infiltrating immune cells, blocking its interactions with both PD-1 and B7.1 receptors. By inhibiting PD-L1, TECENTRIQ may enable the activation of T cells. TECENTRIQ may also affect normal cells.

TECENTRIQ is the first and only anti-PD-L1 cancer immunotherapy approved by the FDA, and is indicated for the treatment of people with locally advanced or metastatic urothelial carcinoma (mUC) who have disease progression during or following platinum-based chemotherapy, or whose disease has worsened within 12 months of receiving platinum-based chemotherapy before surgery (neoadjuvant) or after surgery (adjuvant). This indication for TECENTRIQ is approved under accelerated approval based on tumor response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials.

TECENTRIQ U.S. Indication (pronounced ‘tē-SEN-trik’)

TECENTRIQ is a prescription medicine used to treat:

A type of bladder cancer called urothelial carcinoma. TECENTRIQ may be used when bladder cancer has spread or cannot be removed by surgery (advanced urothelial carcinoma) and,
The patient has tried chemotherapy that contains platinum, and it did not work or is no longer working.
It is not known if TECENTRIQ is safe and effective in children.
