Kura Oncology to Present New Data Supporting Combination of KO-2806 with KRAS G12C and Pan-RAS Inhibitors

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 the upcoming presentation of new preclinical data supporting the combination of its next-generation farnesyl transferase inhibitor (FTI) KO-2806 with targeted therapies, including KRASG12C inhibitors and pan-RAS inhibitors, at the EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics in Barcelona, Spain.

“We look forward to presenting an update to our growing body of preclinical and clinical data that demonstrate the potential of KO-2806 as a companion therapeutic to augment the antitumor activities of KRASG12C and pan-RAS inhibitors,” said Troy Wilson, Ph.D., J.D., President and Chief Executive Officer of Kura Oncology. “These findings support the promising therapeutic strategy of blunting the effects of innate and adaptive resistance to targeted agents to treat cancers driven by KRAS mutations, including KRASG12C non-small cell lung cancer (NSCLC) and KRAS-mutant colorectal cancers. If successful, we believe KO-2806 could drive enhanced antitumor activity and become a combination partner to multiple targeted therapies in large solid tumor indications.”

Details for the session titles and information for the two abstracts are listed below. Copies of the presentations will be available in the Posters and Presentations section on Kura’s website following presentation at the conference.

KO-2806, a next-generation farnesyl transferase inhibitor, re-sensitizes KRAS G12C NSCLC tumors to KRAS G12C mutant-specific inhibitors through mTOR signaling inhibition Session Date and Time: Friday, October 25, 2024; 9:00 AM - 3:00 PM ETSession and Location: Drug Resistance and Modifiers, Exhibition Hall           Poster Number: PB376

The next-generation farnesyl transferase inhibitor KO-2806 sensitizes colorectal cancers to pan-RAS inhibition Session Date and Time: Friday, October 25, 2024; 9:00 AM - 3:00 PM ETSession and Location: Drug Resistance and Modifiers, Exhibition Hall         Poster Number: PB378                   

About KO-2806

KO-2806 is a next-generation inhibitor of farnesyl transferase designed to improve upon the potency, pharmacokinetic and physicochemical properties of earlier FTI drug candidates. At the 2023 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics, Kura presented preclinical data supporting the rationale for combining KO-2806 with distinct classes of targeted therapies, including tyrosine kinase inhibitors, KRASG12C inhibitors and KRASG12D inhibitors. Kura is evaluating KO-2806 in a Phase 1 dose-escalation trial (FIT-001) as a monotherapy, in combination with cabozantinib in clear cell renal cell carcinoma and in combination with adagrasib in KRASG12C NSCLC. Additional information about clinical trials for KO-2806 can be found at https://kuraoncology.com/clinical-trials/#farnesyl-transferase-inhibitor.

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, a once-daily, oral drug candidate targeting the menin-KMT2A protein-protein interaction, has received Breakthrough Therapy Designation from the U.S. Food and Drug Administration for the treatment of relapsed/refractory (R/R) NPM1-mutant AML. Kura has completed enrollment in a Phase 2 registration-directed trial of ziftomenib in R/R NPM1-mutant AML (KOMET-001). The Company is 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. Kura is evaluating KO-2806, a next-generation FTI, in a Phase 1 dose-escalation trial as a monotherapy and in combination with targeted therapies (FIT-001). Tipifarnib, a potent and selective FTI, is currently in a Phase 1/2 trial in combination with alpelisib for patients with PIK3CA-dependent head and neck squamous cell carcinoma (KURRENT-HN).
