SAN DIEGO, April 22, 2024 (GLOBE NEWSWIRE) -- Kura Oncology, Inc. (Nasdaq: KURA), a clinical-stage biopharmaceutical company committed to realizing the promise of precision medicines for the treatment of cancer, today announced that its investigational drug, ziftomenib, has been granted Breakthrough Therapy Designation (BTD) by the U.S. Food and Drug Administration (FDA) for the treatment of patients with relapsed/refractory (R/R) NPM1-mutant acute myeloid leukemia (AML).

FDA granted BTD for ziftomenib based on data from Kura’s ongoing KOMET-001 clinical trial in patients with R/R NPM1-mutant AML. BTD is for a drug that treats a serious or life-threatening condition and for which preliminary clinical evidence indicates the drug may demonstrate substantial improvement on a clinically significant endpoint(s) over available therapies. The designation is intended to expedite development and review of drugs, including an organizational commitment by FDA senior managers and experienced review staff as well as eligibility for rolling review and priority review.¹

“We are highly encouraged by FDA’s decision to grant Breakthrough Therapy Designation to ziftomenib, recognizing its potential as an innovative medicine for patients with relapsed/refractory NPM1-mutant AML,” said Troy Wilson, Ph.D., J.D., President and Chief Executive Officer of Kura Oncology. “NPM1-mutant AML represents approximately 30% of new AML cases annually, and this designation reflects that NPM1-mutant AML is a disease of significant unmet need for which there is no approved targeted therapy as well as the fact that ziftomenib offers potential to demonstrate substantial improvement over available therapies. We remain committed to bringing ziftomenib to the market as quickly as possible and look forward to working more closely with FDA to bring our ziftomenib program to patients in urgent need of effective treatments.”

Kura is on track to complete the registration-directed trial of ziftomenib in R/R NPM1-mutant AML by mid-2024. Ziftomenib is also being evaluated in combination with current standards of care, including venetoclax/azacitidine or cytarabine plus daunorubicin (7+3) in NPM1-mutant and KMT2A-rearranged AML (KOMET-007) and with gilteritinib, FLAG-IDA or LDAC in NPM1-mutant and KMT2A-rearranged AML (KOMET-008).
