Kura Oncology (KURA) filed an 8-K announcing updated Phase 1a/1b results for ziftomenib, its oral menin inhibitor, from the KOMET-007 study in newly diagnosed AML patients with NPM1-m or KMT2A-r mutations. The 600 mg QD dose given with standard 7+3 chemotherapy produced robust composite complete remission (CRc) of 92 % (65/71) and complete remission (CR) of 80 % (57/71), with similar efficacy across both genetic sub-groups (CRc: 93 % NPM1-m, 89 % KMT2A-r). MRD-negative CR rates reached 71 % for NPM1-m and 88 % for KMT2A-r, achieved in roughly 4–5 weeks.
Durability signals are emerging: median CR duration and overall survival have not yet been reached in NPM1-m patients after a median 24.9-week follow-up; KMT2A-r patients show a median CR duration of 25.6 weeks with OS not reached. Survival remains high, with 96 % (NPM1-m) and 88 % (KMT2A-r) alive and on study.
The pooled safety set (n = 82) showed a profile consistent with prior data. ≥Grade 3 treatment-related adverse events >10 % included febrile neutropenia (15 %), thrombocytopenia (15 %), anemia (11 %) and neutropenia (11 %). Importantly, there were no dose-limiting toxicities, meaningful QTc prolongation, drug–drug interactions or additive myelosuppression; a single grade-3 differentiation syndrome case was successfully managed.
Kura plans to initiate the KOMET-017 randomized Phase 3 trials (intensive and non-intensive chemo backbones) in 2H 2025. The company also hosted a virtual investor event on 18 Jun 2025 (Exhibit 99.1) to discuss the data.
