SAN DIEGO, Feb. 26, 2025– Kura Oncology, Inc. (Nasdaq: KURA), a clinical-stage biopharmaceutical company committed to realizing the promise of precision medicines for the treatment of cancer, today reported fourth quarter and full year 2024 financial results and provided a corporate update.

“We are very pleased the KOMET-001 registrational trial achieved its primary endpoint. We look forward to sharing topline data at an upcoming medical conference and expect to submit a New Drug Application (NDA) in relapsed/refractory (R/R) NPM1-mutant acute myeloid leukemia (AML) next quarter,” said Troy Wilson, Ph.D., J.D., President and Chief Executive Officer of Kura Oncology. “In parallel, we are advancing ziftomenib into registrational studies in the frontline (1L) setting. Approximately half of patients with newly diagnosed NPM1-mutated (NPM1-m) AML and 80% of patients with KMT2A-rearranged (KMT2A-r) AML will die from the disease within five years. Given this unmet need, we are pleased to have reached alignment with the U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA) on key aspects of our Phase 3 trials, including the use of minimum residual disease (MRD)-negative complete response (CR) as a primary endpoint for potential accelerated approval in the U.S., with topline results anticipated in 2028. Our KOMET-017 trial is breaking new ground, and we and our partners at Kyowa Kirin are working as rapidly as possible to bring ziftomenib to AML patients worldwide.”

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 targeting cancer signaling pathways. Ziftomenib, a once-daily, oral menin inhibitor, is the first and only investigational therapy to receive Breakthrough Therapy Designation from the FDA for the treatment of R/R NPM1-m AML. In November 2024, Kura Oncology entered a global strategic collaboration agreement with Kyowa Kirin Co., Ltd. to develop and commercialize ziftomenib for AML and other hematologic malignancies. Enrollment in a Phase 2

registration-directed trial of ziftomenib in R/R NPM1-m AML has been completed, and the companies anticipate submission of an NDA to the FDA in the second quarter of 2025. Kura Oncology and Kyowa Kirin are also 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, is being evaluated in a Phase 1 dose-escalation trial as a monotherapy and in combination with targeted therapies. Tipifarnib, a potent and selective farnesyl transferase inhibitor, is currently in a Phase 1/2 trial in combination with alpelisib for patients with PIK3CA-dependent HNSCC.
