Array Gains SPA for Colon Cancer Therapy

Share

Array BioPharma has reached agreement with FDA on a special protocol assessment (SPA) for BEACON CRC, a global Phase 3 trial involving encorafenib and Erbitux (cetuximab), with or without binimetinib, versus standard of care in patients with BRAF-mutant colorectal cancer (CRC) who have previously received first-or second-line systemic therapy. “The SPA provides agreement that the design and planned analysis of BEACON CRC adequately address the objectives necessary to support a regulatory submission for the approval of the doublet regimen of encorafenib and Erbitux,” the company says. The agency also told Array that data from the study showing the triple regimen (encorafenib, Erbitux and binimetinib) both met its primary endpoint (overall survival) as compared to the control arm, and demonstrated a clinically meaningful benefit as compared to the double regimen, would provide support for approval, the company says.

The study is designed to enroll 615 patients who will be randomized 1:1:1 to receive triple therapy (encorafenib, Erbitux and binimetinib), double therapy (encorafenib and Erbitux) or the control arm (irinotecan-based therapy and Erbitux), Array says. The primary endpoint of the trial is overall survival when comparing the triple therapy to the control arm. Secondary endpoints address efficacy of the double therapy compared to the control arm, and the triple therapy compared to the doublet therapy.

Array is conducting BEACON CRC in partnership with Pierre Fabre and Merck KGaA. 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 the MAPK signaling pathway, the company says. This pathway regulates several key cellular activities including proliferation, differentiation, survival and angiogenesis.
