SAN DIEGO, Nov. 07, 2024 (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 third quarter 2024 financial results and provided a corporate update.

“We approach the end of 2024 in a strong position, with a series of important catalysts ahead,” said Troy Wilson, Ph.D., J.D., President and Chief Executive Officer of Kura Oncology. “First, we look forward to sharing a robust dataset from more than 100 patients in our Phase 1a dose-escalation study of ziftomenib in combination with standards of care in acute myeloid leukemia (AML) at the upcoming American Society of Hematology (ASH) Annual Meeting, followed by topline results from our registration-directed trial of ziftomenib in relapsed/refractory (R/R) NPM1-mutant (NPM1-m) AML early next year. In the meantime, we continue to enroll rapidly across all our ziftomenib studies, further supporting the broad development of our menin inhibitor programs.”

Recent Highlights

• Topline results from registration-directed trial of ziftomenib in early 2025 – In May 2024, Kura completed enrollment of 85 patients in the Phase 2 portion of KOMET-001, a registration-directed clinical trial of its menin inhibitor, ziftomenib, in patients with R/R NPM1-m AML. Ziftomenib is the first and only investigational therapy to be granted Breakthrough Therapy Designation (BTD) for the treatment of R/R NPM1-m AML, which accounts for approximately 30% of new AML cases annually and represents a disease of significant unmet need for which no approved targeted therapy exists. Results from the Phase 1 portion of KOMET-001 were recently published in the leading clinical oncology journal, The Lancet Oncology.
• Data from Phase 1a dose-escalation study of ziftomenib at ASH – Two abstracts reporting preliminary data from the Phase 1a dose-escalation study of ziftomenib in combination with standards of care in patients with NPM1-m and KMT2A-rearranged (KMT2A-r) AML have been accepted for presentation at the ASH Annual Meeting in December. As of the June 21, 2024 data cutoff, the abstracts continue to support a potential best-in-class safety and tolerability profile for ziftomenib, as well as robust and durable activity in combination with standards of care, including venetoclax plus azacitidine (ven/aza) as well as cytarabine plus daunorubicin (7+3). Kura expects to present a more mature dataset from more than 100 patients in the Phase 1a dose-escalation study in the presentations at ASH.
• Phase 1b expansion study of ziftomenib now enrolling in all cohorts – All four cohorts in the Phase 1a dose-escalation study have cleared the highest dose and advanced into the Phase 1b expansion study at 600 mg. The Phase 1b expansion study includes multiple combination cohorts, including ziftomenib plus ven/aza in newly diagnosed NPM1-m or KMT2A-r AML and ziftomenib plus 7+3 in newly diagnosed NPM1-m or KMT2A-r AML without qualification for high-risk disease. Each of the seven combination cohorts is expected to enroll at least 20 patients. A total of 45 patients have already enrolled in the study since the first dose-expansion cohort opened in August 2024. The Company anticipates sharing preliminary data from the Phase 1b expansion study at a medical meeting in 2025.
• Preclinical data support opportunity for ziftomenib in GIST – Last month, at the EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics in Barcelona, Kura reported preclinical data supporting the combination of ziftomenib and imatinib for the treatment of advanced gastrointestinal stromal tumors (GIST). The combination showed unexpectedly robust and durable antitumor activity in both imatinib-sensitive and imatinib-resistant GIST patient-derived xenograft models, and in all cases was significantly superior to imatinib monotherapy. The Company received FDA clearance of its Investigational New Drug application for ziftomenib for the treatment of advanced GIST in August and expects to initiate a proof-of-concept study in the first half of 2025 evaluating ziftomenib and imatinib in patients with advanced GIST who have failed imatinib.
• First patient dosed in study of KO-2806 and adagrasib in KRAS^G12C-mutated NSCLC – In August 2024, Kura began dosing patients in its study of KO-2806, a next-generation farnesyl transferase inhibitor (FTI), in combination with adagrasib in KRAS^G12C-mutated non-small cell lung cancer (NSCLC). The Company’s findings suggest that combining KO-2806 with adagrasib may drive tumor regressions and enhance both duration and depth of antitumor response in preclinical models of KRAS^G12C-mutated NSCLC. The study of KO-2806 and adagrasib is supported by a clinical collaboration and supply agreement with Mirati, now a Bristol Myers Squibb company.
• Preclinical data support potential for menin inhibitor in diabetes – In June 2024, Kura reported data showing that ziftomenib induces insulin production, improves insulin sensitivity and reduces insulin resistance in a preclinical in vivo model of type 2 diabetes. Ziftomenib demonstrated meaningful levels of glycemic control, including reduced fasting blood glucose levels and %HbA1C within 27 days, as well as consistent improvement in both insulin sensitivity and insulin production. The data were presented at the American Diabetes Association Scientific Sessions in Orlando. The Company expects to nominate a next generation menin inhibitor candidate targeting diabetes in the first half of 2025.
