Question · Q3 2025
Ren Benjamin asked if there was a strategy to combine Ruxolitinib XR with a pipeline product or in-license a product to mitigate LOE erosion. He also inquired about the registrational program for TGF-beta, asking about the study size, the required delta for a positive study, and the calculus given limited data.
Answer
CEO Bill Meury stated the current focus for XR is launching it for Jakafi indications, with no plans for combinations in development to fight LOE erosion. Chief Medical Officer Steven Stein explained the Phase 3 study for TGF-beta will be in first-line MSS colorectal cancer, combining with FOLFOX and BEV. The primary endpoint will be PFS, with benchmarks available for PFS and OS. The study size will be north of 500 patients and well-powered to show the desired PFS advantage.
