Kura Oncology Receives FDA Authorization to Proceed with Phase 1b Study of KO-539 in Acute Myeloid Leukemia
– FDA lifts partial clinical hold following agreement on mitigation strategy for differentiation syndrome –
– KOMET-001 study to resume screening and enrollment of new patients –
– Encouraging safety, tolerability and clinical activity observed among patients on study –
“I am very proud of our team for working diligently with the FDA and site investigators to resolve the partial clinical hold in such a timely manner,” said
KOMET-001 (Kura Oncology Menin Inhibitor Trial) is a Phase 1/2, first-in-human, open-label trial to determine the safety, tolerability and anti-tumor activity of KO-539 in patients with refractory or relapsed AML. KO-539 demonstrated a wide therapeutic window in the Phase 1a dose-escalation portion of KOMET-001, with promising single-agent activity in an all-comer population of patients with relapsed or refractory AML, including patients with NPM1 mutations and KMT2A rearrangements. The Phase 1b portion includes two expansion cohorts – a lower dose of 200 mg and a higher dose of 600 mg. Kura expects to enroll 12 patients with NPM1-mutant or KMT2A-rearranged relapsed or refractory AML in each cohort and assess those patients for safety and tolerability, pharmacokinetics and efficacy to determine the recommended Phase 2 dose for KO-539.
