Array BioPharma And Pierre Fabre To Present Phase 3 COLUMBUS Trial At Society For Melanoma Research Annual Congress

BOULDER, Colo., and CASTRES, France, Oct. 25, 2016 /PRNewswire/ -- Array BioPharma (NASDAQ: ARRY) and Pierre Fabre announced today that results from the Phase 3 COLUMBUS trial of binimetinib and encorafenib in BRAF-mutant melanoma will be presented at the 2016 Society for Melanoma Research (SMR) Annual Congress in Boston, Massachusetts on November 9. Findings from COLUMBUS evaluating the combination of encorafenib plus binimetinib ("combination") in patients with unresectable or metastatic BRAF-mutant melanoma will be presented as an oral, late-breaking abstract.  Two data analyses from the NEMO Phase 3 trial will also be presented, which evaluated binimetinib in patients with NRAS-mutant melanoma.

COLUMBUS TRIAL DATA

Data from the Phase 3 study will be featured as an oral presentation during the late-breaking abstract session on Wednesday, November 9 from 10:00 – 10:15 AM ET:

• Abstract 2617508: Results of COLUMBUS Part 1: A Phase 3 Trial of Encorafenib (ENCO) Plus Binimetinib (BINI) Versus Vemurafenib (VEM) or ENCO in BRAF-Mutant Melanoma
  • Presenter: Keith T. Flaherty, M.D., Director of the Termeer Center for Targeted Therapy, Massachusetts General Hospital and Professor of Medicine, Harvard Medical School, Boston, Massachusetts

As reported in late September, 577 patients were randomized 1:1:1 to receive the combination of encorafenib plus binimetinib, encorafenib alone, or vemurafenib alone. In the analysis of the primary endpoint, the median PFS for patients treated with the combination of encorafenib plus binimetinib ("combination") was 14.9 months versus 7.3 months for patients treated with vemurafenib; HR (0.54), [95% CI 0.41-0.71], p<0.001. Analysis of a secondary endpoint comparing the PFS of patients treated with combination to patients treated with encorafenib showed a median of 14.9 months versus 9.6 months with HR (0.75), [95% CI 0.56-1.00], p=0.051, which did not reach statistical significance. The combination was generally well-tolerated and reported adverse events were overall consistent with previous combination encorafenib plus binimetinib clinical trial results in BRAF-mutant melanoma patients.

ARRAY BIOPHARMA INVESTOR RECEPTION

Array will be hosting an investor reception immediately following the conclusion of SMR.  The event will be held on Wednesday, November 9 from 1 – 3 pm ET in Boston and will include an encore presentation of the COLUMBUS results by Dr. Flaherty at 1 pm ET.  The public is welcome to participate in the presentation through a webcast (live and replay):  http://edge.media-server.com/m/p/jmj68buy

About Metastatic 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 over 10,000 deaths from the disease expected in 2016. Novel therapies that target the RAS/RAF/MEK/ERK pathway have a strong scientific rationale for activity in advanced melanoma, as up to 50 percent of patients with metastatic melanoma have activating BRAF mutations, the most common gene mutation in this patient population. Activating NRAS mutations are present in up to 20 percent of patients with metastatic melanoma, and is a poor prognostic indicator for these patients.

About Binimetinib & Encorafenib
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 and encorafenib is a late-stage small molecule BRAF inhibitor, both of which target key enzymes in this pathway.

Binimetinib and encorafenib are being studied in clinical trials in advanced cancer patients, including the recently initiated Phase 3 BEACON CRC trial that is evaluating encorafenib in combination with cetuximab with or without binimetinib in patients with BRAF V600E-mutant colorectal cancer. Array submitted a New Drug Application (NDA) for binimetinib in NRAS-mutant melanoma to the FDA at the end of June 2016. The FDA accepted the NDA with a target action date under the Prescription Drug User Fee Act (PDUFA) of June 30, 2017.  Array also expects to submit an NDA for binimetinib and encorafenib in BRAF-mutant melanoma to the FDA in 2017.

Array BioPharma retains exclusive rights to binimetinib and encorafenib in key markets including the U.S., Japan, Canada, Korea and Israel. Pierre Fabre will have exclusive rights to commercialize both products in all other countries, including Europe, Asia and Latin America.

Array BioPharma Forward-Looking Statement
This press release contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including statements about the future development plans of binimetinib and encorafenib, and the timing of the announcement of further results of clinical trials for binimetinib and encorafenib; expectations regarding the timing of regulatory filings for binimetinib and encorafenib and regarding approval of binimetinib and encorafenib for BRAF-mutant melanoma; expectations that events will occur that will result in greater value for Array; and the potential for the results of current and further clinical trials to support regulatory approval or the marketing success of binimetinib and encorafenib. Specifically, there is no assurance that results from the COLUMBUS study, including Parts 1 and 2, will satisfy the requirements of regulatory authorities necessary to file an application for marketing approval, or that if such application is accepted, that it will be approved.  These statements involve significant risks and uncertainties, including those discussed in our most recent annual report filed on Form 10-K, in our quarterly reports filed on Form 10-Q, and in other reports filed by Array with the Securities and Exchange Commission. Because these statements reflect our current expectations concerning future events, our actual results could differ materially from those anticipated in these forward-looking statements as a result of many factors. These factors include, but are not limited to, the determination by the FDA that results from clinical trials are not sufficient to support registration or marketing approval of binimetinib and encorafenib; our ability to effectively and timely conduct clinical trials in light of increasing costs and difficulties in locating appropriate trial sites and in enrolling patients who meet the criteria for certain clinical trials; risks associated with our dependence on third-party service providers to successfully conduct clinical trials within and outside the United States; our ability to achieve and maintain profitability and maintain sufficient cash resources; and our ability to attract and retain experienced scientists and management. We are providing this information as of October 25, 2016. We undertake no duty to update any forward-looking statements to reflect the occurrence of events or circumstances after the date of such statements or of anticipated or unanticipated events that alter any assumptions underlying such statements.
