All Magrolimab Studies Re-Opening for Patient Enrollment in the U.S.

Foster City, Calif., June 3, 2022 – Gilead Sciences, Inc. (Nasdaq: GILD) today announced the U.S. Food and Drug Administration (FDA) has lifted the remaining partial clinical hold on studies evaluating magrolimab as a potential treatment for lymphoma and multiple myeloma (MM). The FDA decision followed a comprehensive review of the safety data from the magrolimab lymphoma study. The hold was removed without further modification of our safety language and no new safety signals were identified.

As previously announced, the partial clinical hold for studies investigating magrolimab in combination with azacitidine in myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) was lifted by FDA on April 11. Together with the action announced today, all magrolimab studies have been cleared to resume in the U.S. Gilead is in the process of re-activating all studies globally, and already received approval to restart patient enrollment in multiple countries including France, Germany, and the United Kingdom. The Phase 3 ENHANCE study in MDS, which met the pre-specified enrollment threshold before the partial clinical hold, remains on track for the first interim readout in 1H23.

“Hematologic cancers are often associated with poor prognosis and there is an urgent need for better treatment options,” said Merdad Parsey, MD, PhD, Chief Medical Officer, Gilead Sciences. “Gilead remains focused on the magrolimab program and potential to impact patients with unmet need. We appreciate the FDA’s timely lift of the partial clinical holds, allowing us to re-activate enrollment in our trials as quickly as possible as we work to advance our investigational CD47 antibody therapy.”
