SAN DIEGO and TOKYO, May 14, 2025 (GLOBE NEWSWIRE) — Kura Oncology, Inc. (Nasdaq: KURA, “Kura”) and Kyowa Kirin Co., Ltd. (TSE: 4151, “Kyowa Kirin”) today announced that an abstract highlighting clinical data from the KOMET-007 combination trial of ziftomenib, a once-daily, oral investigational menin inhibitor, has been accepted for presentation at the upcoming 2025 European Hematology Association (EHA) Congress, to be held in Milan, Italy, from June 12-15, 2025.

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 EHA will be from the Phase 1a dose-escalation and Phase 1b dose-expansion portions of the trial, in the cohort evaluating ziftomenib in combination with 7+3 in newly diagnosed patients with AML.

“The latest findings from the KOMET-007 trial underscore the potential of the combination of ziftomenib with intensive chemotherapy for newly diagnosed patients, strengthening our confidence in its role as a potential treatment option for a broad segment of the AML community,” said Mollie Leoni, M.D., Chief Medical Officer of Kura Oncology. “The Phase 1a/b KOMET-007 trial positions us to further evaluate this combination, and its potential to expand treatment options for AML patients, in the upcoming pivotal Phase 3 KOMET-017 trial.”

In addition to the oral presentation, two abstracts for the KOMET-001 and KOMET-017 trials have been accepted for an encore presentation and publication, respectively. Session titles and information for all three abstracts are listed below and are now available on the EHAweb.org website. Updated data from the published abstract for KOMET-007 will be disclosed during the oral presentation.

About Kura Oncology

Kura Oncology is a clinical-stage biopharmaceutical company committed to realizing the promise of precision medicines for the treatment of cancer. The Company’s pipeline consists of small molecule drug candidates designed to target cancer signaling pathways. Ziftomenib, a once-daily, oral menin inhibitor, is the first and only investigational therapy to receive Breakthrough Therapy Designation from the U.S. Food and Drug Administration (FDA) for the treatment of relapsed or refractory (R/R) NPM1-m AML. In November 2024, Kura Oncology entered into a global strategic collaboration agreement with Kyowa Kirin to develop and commercialize ziftomenib for AML and other hematologic malignancies. Enrollment in KOMET-001, a Phase 2 registration-directed trial of ziftomenib in R/R NPM1-m AML, has been completed, and in the second quarter of 2025, the companies announced submission of a New Drug Application for ziftomenib for the treatment of adult patients with R/R NPM1-m AML. Kura and Kyowa Kirin are conducting a series of clinical trials to evaluate ziftomenib in combination with current standards of care in newly diagnosed and R/R NPM1-m and KMT2A-r AML. KO-2806, a next-generation farnesyl transferase inhibitor (FTI), is being evaluated in a Phase 1 dose-escalation trial (FIT-001) as a monotherapy and in combination with targeted therapies for patients with various solid tumors. Tipifarnib, a potent and selective FTI, is currently in a Phase 1/2 trial (KURRENT-HN) in combination with alpelisib for patients with PIK3CA-dependent HNSCC.
