SAN DIEGO, Aug. 05, 2021 (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 reported second quarter 2021 financial results and provided a corporate update.

"I am extremely proud of the progress our team has made over the past several months, underscoring our focus on operational execution," said Troy Wilson, Ph.D., J.D., President and Chief Executive Officer of Kura Oncology. "We continue to have strong conviction in KO-539 and its potential to be both a first-in-class and a best-in-class menin inhibitor. This confidence is supported by clinical data from KOMET-001, our Phase 1/2 trial of KO-539 in patients with relapsed or refractory acute myeloid leukemia (AML). Given the wide therapeutic window KO-539 demonstrated in the Phase 1a dose escalation portion of the trial, we have now advanced into the Phase 1b expansion cohorts in patients with NPM1-mutant and KMT2A-rearranged relapsed/refractory AML. The Phase 1b enables us to refine the selection of a recommended Phase 2 dose while maintaining an aggressive development timeline for the program."

"Although it is early and the results are still preliminary," continued Dr. Wilson, "we are encouraged by observations of early signs of clinical activity in the Phase 1b expansion cohorts. We are also encouraged by the rate of patient screening and enrollment, an indication of the enthusiasm of the investigators as well as the strong execution of our clinical operations team. We intend to provide an update on both the Phase 1a and the Phase 1b at a future medical meeting, pending determination of the recommended Phase 2 dose. In the meantime, we look forward to providing qualitative updates on the progress of the Phase 1b in the months ahead."

Recent Highlights

First patients dosed in Phase 1b expansion cohorts with KO-539 – In late June, Kura announced that the first patient was dosed in the Phase 1b portion of KOMET-001. Patients are now enrolled in each of the two expansion cohorts – a lower dose of 200 mg and a higher dose of 600 mg – each comprising NPM1-mutant and KMT2A-rearranged relapsed/refractory AML patients. The Company expects to complete enrollment of 12 evaluable patients in each cohort by the first quarter of 2022, then will assess those patients for safety and tolerability, pharmacokinetics and efficacy in order to determine the recommended Phase 2 dose.

Multiple expansion opportunities in acute leukemias – Pending determination of a recommended Phase 2 dose, Kura is preparing to conduct a comprehensive clinical development plan for KO-539, aimed at broadening the opportunity in acute leukemias. Additional development opportunities include combination studies, other genetic subtypes, a pediatric development strategy and other indications, such as acute lymphocytic leukemia and myelodysplastic syndrome.

Clinical collaboration to evaluate tipifarnib and alpelisib in HNSCC – In July, Kura announced a clinical collaboration with Novartis to evaluate the combination of tipifarnib and the PI3Kα inhibitor alpelisib in patients with head and neck squamous cell carcinoma (HNSCC). The Company is now preparing for a Phase 1/2 clinical trial (KURRENT) of tipifarnib in combination with alpelisib in patients who have HRAS- and/or PIK3CA-dependent HNSCC. The initial cohort will include patients who have PIK3CA-dependent HNSCC and the trial is expected to initiate in the fourth quarter of 2021.

Nomination of KO-2806 as lead development candidate – Kura has nominated KO-2806 as its lead development candidate in the Company's next-generation farnesyl transferase inhibitor program. KO-2806 was nominated based on its improved potency, pharmacokinetic and physicochemical properties relative to tipifarnib, and is designed to target innovative biology and address large oncology indications of high unmet need through rational combinations. The Company is now conducting investigational new drug (IND)-enabling studies and expects to submit an IND application for KO-2806 by the end of 2022.

Addition of industry veterans to board of directors – Kura recently appointed Carol Schafer and Helen Collins, M.D. to its board of directors. Ms. Schafer brings more than 25 years of experience as a strategic and financial advisor to the leadership teams of growing biopharmaceutical companies, most recently as Vice Chair of Equity Capital Markets at Wells Fargo Securities. Dr. Collins joins with more than 25 years of medical experience, most recently as Chief Medical Officer at Five Prime Therapeutics, where she was responsible for the strategy and execution of the company's clinical development plans until its acquisition by Amgen in April 2021.
