FDA Accepts Array Bio NDA for Melanoma Drug

Share

FDA has accepted for review an Array BioPharma NDA for binimetinib for treating certain patients with melanoma. The agency has set a user fee review target date of 6/30/2017. The submission is based on data from the company’s Phase 3 NEMO (NRAS MELANOMA AND MEK INHIBITOR) trial in patients with NRAS-mutant melanoma. FDA has told the company that it plans to hold an advisory committee meeting as part of the review process. Array says it is currently preparing for an Application Orientation Meeting (AOM) with the agency this month which should include a discussion of the NDA package and clinical risk/benefit.

The NEMO trial compared binimetinib 45mg to dacarbazine 1,000 mg. The study met its primary endpoint of improving progression-free survival (PFS), with median PFS on the binimetinib arm at 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,” Array says.
