SAN DIEGO, March 26, 2025 (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 an abstract containing preclinical data for KO-2806, the Company's next-generation farnesyl transferase inhibitor (FTI), in combination with cabozantinib, a tyrosine kinase inhibitor (TKI), in clear cell renal cell carcinoma (ccRCC), has been accepted for an oral presentation at the upcoming American Association for Cancer Research (AACR) Annual Meeting in Chicago, IL on April 29, 2025.

"The latest findings for our next-generation farnesyl transferase inhibitor, KO-2806, being presented at this year's AACR Annual Meeting, add to the growing body of data demonstrating the potential of FTIs as companion therapeutic agents to augment the antitumor activities of various targeted therapies and to overcome resistance in combination," said Francis Burrows, Ph.D., Chief Scientific Officer of Kura Oncology. "We continue to make good progress in our FIT-001 trial evaluating KO-2806 in solid tumor indications where there is unmet medical need, and we look forward to presenting the first clinical data for KO-2806 as monotherapy and in combination with cabozantinib for the treatment of RCC later this year."

The title and session information for the oral presentation are listed below. Full abstract details including title and text are currently available to registrants via the AACR online itinerary planner.

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 U.S. Food and Drug Administration (FDA) for the treatment of relapsed/refractory (R/R) NPM1-mutant acute myeloid leukemia (AML). In November 2024, Kura Oncology entered into 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-mutant AML has been completed, and the companies anticipate submission of a New Drug Application (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-mutant and KMT2A-rearranged 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.  For additional information, please visit Kura's website at www.kuraoncology.com and follow us on X and LinkedIn.
