Curis, Inc. announced that the U.S. Food and Drug Administration (FDA) has notified Curis that it may resume enrollment of additional patients in the monotherapy phase of the TakeAim Leukemia study. Previously, Curis announced that the FDA had placed partial clinical holds on the TakeAim Leukemia and TakeAim Lymphoma studies in April 2022. On August 18, 2022, Curis reported that the partial clinical hold on the TakeAim Lymphoma study was lifted.

After review of the comprehensive data package submitted by Curis, the FDA has notified Curis that it may resume enrollment of additional patients in the monotherapy dose finding phase (Phase 1a) of the TakeAim Leukemia study, in which the company has agreed to enroll at least nine additional patients at the 200mg dose level. The partial hold remains in place for the combination therapy phase (Phase 1b) and the expansion phase (Phase 2a) of the study until Phase 1a is complete and the FDA approves proceeding to the next phases of the study. Before lifting the restriction on patient enrollment, the FDA reviewed additional data provided by the company related to the risk of rhabdomyolysis, a side effect also associated with statins, as well as with cancer medications such as Odomzo® and Cotellic®.

The FDA also reviewed the company's strategy for utilizing objective laboratory measurements, similar to those used with Odomzo and Cotellic, to identify rhabdomyolysis, as well as the company's strategy for managing rhabdomyolysis, if it is detected. Similar to the TakeAim Lymphoma study, the Company is updating its timeline for clinical data release to reflect the availability of updated preliminary data from the TakeAim Leukemia study in 2023. In addition, Curis is proactively discussing the clinical plans for emavusertib in leukemia, including alignment on optimal dose and development path, with the FDA's leukemia division.
