BMS Faces Setback in Phase III Myelofibrosis Trial for Anemia Drug Reblozyl
SHERIDAN, WYOMING – July 21, 2025 – Bristol Myers Squibb’s (BMS) leading anemia therapy, Reblozyl, has failed to meet its primary endpoint in a pivotal Phase III trial for myelofibrosis-associated anemia, highlighting the ongoing challenges in addressing this difficult-to-treat condition.
The INDEPENDENCE study, designed to evaluate Reblozyl's ability to reduce patients’ dependence on red blood cell transfusions, did not achieve statistical significance on its primary objective—independence from transfusions for 12 consecutive weeks within the first 24 weeks of treatment. The company disclosed the outcome in a news release last Friday but withheld detailed data on transfusion independence rates.
