Initial real-world data and an IMpactMF interim read are expected in the second half of 2026.

Overview

  • Management issued 2026 operating expense guidance of $230–$240 million, reflecting lower spending after a December 2025 restructuring.

  • Commercial efforts center on an estimated 8,000 eligible second-line, lower-risk MDS patients in the U.S., with growth expected to be weighted to the back half of 2026.
  • The company backs 10+ investigator-sponsored studies and real-world evidence efforts, and anticipates the fully enrolled IMpactMF trial to hit its interim trigger in H2 2026.
