– Presentations to highlight preclinical data supporting combination of FTIs with KRASG12C inhibitors and tyrosine kinase inhibitors – SAN DIEGO, March 14, 2023 (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 have been accepted for presentation at the upcoming American Association for Cancer Research (AACR) Annual Meeting, to be held in Orlando from April 14-19, 2023. “We look forward to presenting preclinical data supporting the combination of farnesyl transferase inhibitors (FTIs) with KRASG12C inhibitors and tyrosine kinase inhibitors at this year’s AACR Annual Meeting,” said Troy Wilson, Ph.D., J.D., President and Chief Executive Officer of Kura Oncology. “These data add to the emerging body of evidence supporting the potential to use FTIs as combination agents to prevent or delay emergence of resistance to certain classes of targeted therapy. We recently announced FDA clearance of the Investigational New Drug application for our next-generation farnesyl transferase inhibitor, KO-2806, which was designed to improve upon potency, pharmacokinetic and physicochemical properties of earlier FTI drug candidates, and we look forward to initiating our FIT-001 Phase 1 trial with KO-2806 later this year.” Session titles and information for the two abstracts are listed below and are now available on 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 that target cancer signaling pathways. Ziftomenib is a once-daily, oral drug candidate targeting the menin-KMT2A protein-protein interaction for the treatment of genetically defined AML patients with high unmet need. The Company is currently enrolling patients in a Phase 2 registration-directed trial (KOMET-001) of ziftomenib in NPM1-mutant relapsed or refractory AML. Kura is preparing to initiate multiple Phase 1 trials to evaluate ziftomenib in combination with current standards of care in earlier lines of therapy and across multiple patient populations, including NPM1-mutant and KMT2A-rearranged AML. 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. Kura intends to evaluate KO-2806, a next-generation FTI, in a Phase 1 dose-escalation trial (FIT-001) as a monotherapy and in combination with other targeted therapies in adult patients with advanced solid tumors.
