Kura Oncology to Present Updated Data from KOMET-007 Combination Trial of Ziftomenib at ASH Annual Meeting

– Ziftomenib combined with 7+3 in 1L NPM1-m or KMT2A-r adverse risk AML patients selected for oral presentation on Saturday, December 7^th –

– Ziftomenib combined with ven/aza in R/R NPM1-m or KMT2A-r AML patients selected for poster presentation on Sunday, December 8th –

SAN DIEGO, Nov. 05, 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 two abstracts highlighting clinical data from the KOMET-007 combination trial of ziftomenib, the Company’s potent and selective menin inhibitor, have been accepted for presentation at the upcoming American Society of Hematology (ASH) Annual Meeting, to be held in San Diego from December 7-10, 2024.

KOMET-007 is a multicenter Phase 1 trial of ziftomenib in combination with standards of care, including cytarabine plus daunorubicin (7+3) and venetoclax/azacitidine (ven/aza), in patients with NPM1-mutant (NPM1-m) and KMT2A-rearranged (KMT2A-r) acute myeloid leukemia (AML). The data presented at ASH will be from the Phase 1a dose-escalation portion of the study, which was conducted in newly diagnosed patients with adverse risk in combination with 7+3 and in relapsed/refractory patients with ven/aza. Notably, all four cohorts in the Phase 1a dose-escalation portion of KOMET-007 have cleared the highest dose and have advanced into the Phase 1b expansion study at 600 mg.

“The growing body of clinical data continue to support a potential best-in-class safety and tolerability profile for ziftomenib, as well as robust and durable activity in combination with standards of care,” said Troy Wilson, Ph.D., J.D., President and Chief Executive Officer of Kura Oncology. “In the relapsed/refractory AML setting, ziftomenib combined with ven/aza is well tolerated and continues to demonstrate encouraging activity in R/R patients, including activity in previously ven-exposed NPM1-m and KMT2A-r patients. No DLTs or ziftomenib-induced QTc prolongation were reported, and events of differentiation syndrome were mitigated in combination.”

“In the AML frontline population, we are very encouraged by the safety and tolerability profile and high rates of complete response and MRD negativity as of the abstract’s June 21^st data cutoff,” Dr. Wilson continued. “We are particularly encouraged by the fact that, in the context of the very challenging 7+3 adverse risk AML patient cohorts, 100% (15/15) of the NPM1-m AML patients and 84% (16/19) of the KMT2A-r patients remained on study as of the data cutoff, approximately one year after study start. These preliminary results support the potential for ziftomenib to transform the standard of care in these high-risk patients. We look forward to sharing a more mature dataset from more than 100 patients, including data from the 600 mg cohorts, in the Phase 1a dose-escalation portion of KOMET-007, at the ASH Annual Meeting next month.”

Session titles and information for the two abstracts are listed below and are now available on the ASH online itinerary planner.
