January 31, 2018 — Vertex announced the selection of two next-generation correctors, VX-659 and VX-445, to advance into Phase 3 development as part of two different triple combination regimens for people with cystic fibrosis (CF). This decision was based on positive initial Phase 2 data. Regulatory discussions are ongoing to finalize the design of Phase 3 programs. Upon completion of these discussions, Vertex plans to initiate the first Phase 3 triple combination program in the first half of 2018 to evaluate VX-659 in triple combination, and a second Phase 3 program in mid-2018 to evaluate VX-445 in triple combination.
