"2025 was a transformative year for Disc, marked by strong execution across our portfolio and meaningful progress toward becoming a fully integrated clinical and commercial organization," said John Quisel, J.D., Ph.D., President and Chief Executive Officer of Disc. "Most notably, bitopertin received CNPV designation and we submitted our NDA under the accelerated approval pathway, positioning the NDA for rapid review by the FDA. We also reported positive initial Phase 2 data from the RALLY-MF study of DISC-0974 in anemia of myelofibrosis, demonstrating robust and broad hematologic activity, and advanced our third program DISC-3405 into proof-of-concept studies for polycythemia vera and sickle cell disease."
"As we look ahead to 2026, we are entering an exciting and pivotal period for Disc," continued Dr. Quisel. "We are preparing to execute a successful US launch of bitopertin for EPP while continuing enrollment in the global APOLLO confirmatory study. Across our pipeline, we expect multiple Phase 2 updates for DISC-0974 and DISC-3405, including important regulatory interactions and expansion into new indications. Together, we believe these milestones position Disc for sustained growth as we work to deliver meaningful new therapies to patients with serious hematologic diseases."
