– KOMET-001 registrational trial in R/R NPM1-mutant AML achieved primary endpoint – – Alignment reached with FDA and EMA on key aspects of the KOMET-017 protocol including use of MRD-negative CR endpoint for potential U.S. accelerated approval pathway in frontline intensive chemotherapy trial – – Topline MRD-negative CR results from KOMET-017-IC Phase 3 trial anticipated in 2028 – – Multiple data presentations for ziftomenib and pipeline programs expected throughout 2025 – – $727.4 million in cash, together with anticipated collaboration agreement payments, to support ziftomenib commercialization through the frontline AML combination setting – – Management to host webcast and conference call today at 4:30 p.m. ET – SAN DIEGO , Feb. 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 reported fourth quarter and full year 2024 financial results and provided a corporate update. “We are very pleased the KOMET-001 registrational trial achieved its primary endpoint. We look forward to sharing topline data at an upcoming medical conference and expect to submit a New Drug Application (NDA) in relapsed/refractory (R/R) NPM1-mutant acute myeloid leukemia (AML) next quarter,” said Troy Wilson , Ph.D., J.D., President and Chief Executive Officer of Kura Oncology . “In parallel, we are advancing ziftomenib into registrational studies in the frontline (1L) setting. Approximately half of patients with newly diagnosed NPM1-mutated (NPM1-m) AML and 80% of patients with KMT2A-rearranged (KMT2A-r) AML will die from the disease within five years. Given this unmet need, we are pleased to have reached alignment with the U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA) on key aspects of our Phase 3 trials, including the use of minimum residual disease (MRD)-negative complete response (CR) as a primary endpoint for potential accelerated approval in the U.S. , with topline results anticipated in 2028. Our KOMET-017 trial is breaking new ground, and we and our partners at Kyowa Kirin are working as rapidly as possible to bring ziftomenib to AML patients worldwide.” Recent Highlights Positive topline results from registration-directed trial of ziftomenib in R/R NPM1-m AML – Kura and Kyowa Kirin announced positive topline results from KOMET-001, the Phase 2 registration-directed trial of ziftomenib in patients with R/R NPM1-m AML. The KOMET-001 trial achieved its primary endpoint, consistent with the targeted 20-30% CR/CR with partial hematological recovery (CRh) rate, and data have been submitted for presentation at ASCO. The benefit-risk profile for ziftomenib is highly encouraging, and safety and tolerability were consistent with previous reports. Facilitated by the Breakthrough Therapy Designation status of ziftomenib in R/R NPM1-m AML, the Company completed its pre-NDA meeting with FDA and anticipates submitting an NDA in the second quarter of 2025. Positive feedback from FDA for 1L combination trial designs – Earlier this month, Kura and Kyowa Kirin announced alignment with FDA on the KOMET-017 global trial protocol evaluating ziftomenib in combination with both intensive and non-intensive combination regimens in patients with newly diagnosed NPM1-m and/or KMT2A-r AML. This includes alignment on potential pathways for accelerated approval in the U.S. in both the KOMET-017-IC (intensive chemotherapy) and KOMET-017-NIC (non-intensive chemotherapy) trials by allowing the trials to use MRD-negative CR and CR, as primary endpoints, respectively. The companies also gained alignment with the EMA on the KOMET-017 protocol, and expect to initiate the KOMET-017 Phase 3 trials in the second half of 2025. Positive clinical data for Phase 1 trial of ziftomenib in combination with standards of care – In December 2024 , Kura Oncology and Kyowa Kirin announced encouraging clinical data from KOMET-007, a Phase 1 trial of ziftomenib in combination with standards of care, including cytarabine/daunorubicin (7+3) and venetoclax/azacitidine in patients with NPM1-m and KMT2A-r AML. Among response-evaluable patients enrolled in the 7+3 combination cohort for patients with 1L NPM1-m or KMT2A-r adverse risk AML, 91% achieved a CR (100% for NPM1-m, 83% for KMT2A-r patients). Ziftomenib was generally well tolerated in combination at all dose levels evaluated across all cohorts in the Phase 1a dose-escalation portion of the trial. The positive results from KOMET-007 reported at ASH reinforce the companies’ commitment to evaluating ziftomenib across the continuum of 1L AML treatment options. Global strategic collaboration with Kyowa Kirin to develop and commercialize ziftomenib in acute leukemias – In November 2024 , Kura Oncology and Kyowa Kirin announced they entered into a global strategic collaboration to develop and commercialize ziftomenib (Kyowa Agreement), funding the expansive AML development program through U.S. commercialization in 1L combinations. Under the partnership, Kura retains leadership and key strategic rights to ziftomenib in the U.S. and preserves strategic flexibility, while enabling development and commercialization of ziftomenib across the continuum of care in acute leukemias, including both fit and unfit 1L indications, post-transplant maintenance setting and combinations with targeted therapies. Preclinical data supporting opportunity for ziftomenib in treatment of gastrointestinal stromal tumors (GIST) – In October 2024 , Kura reported preclinical data presented at the 36th EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics in Barcelona , supporting the potential for ziftomenib in combination with KIT inhibitors for GIST patients. The combination of ziftomenib and imatinib demonstrated robust and durable antitumor activity in imatinib-sensitive (1L) and imatinib-resistant (2L/3L) GIST patient-derived xenograft models. Sixty percent of patients develop resistance to imatinib within two years and ziftomenib has the potential to delay the onset of resistance to, or overcome resistance in patients pre-treated with, imatinib. In August 2024 , Kura announced clearance by the FDA of an IND application and the Company remains on track to initiate the KOMET-015 trial evaluating ziftomenib plus imatinib in patients with advanced GIST, in the first half of 2025. Clinical and preclinical data support combinations of farnesyl transferase inhibitors with targeted therapies – Despite multiple advances, innate and adaptive resistance remain a challenge for many classes of targeted therapies in cancer. A growing body of clinical and preclinical data demonstrates the potential of farnesyl transferase inhibitors as companion therapeutic agents to augment the antitumor activities of various targeted therapies and overcome resistance in combination. Enrollment in the FIT-001 trial evaluating our next-generation farnesyl transferase inhibitor KO-2806 continues to progress and the dose-escalation portion of the KURRENT-HN trial with tipifarnib is now complete. Kura expects to present the first clinical data for KO-2806 as a monotherapy and in combination, as well as clinical data from the KURRENT-HN trial, in the second half of 2025. Financial Results Collaboration revenue from our Kyowa Kirin partnership for the fourth quarter and full year 2024 was $53.9 million , compared to no revenue in 2023. Research and development (R&D) expenses for the fourth quarter of 2024 were $52.3 million , compared to $32.5 million for the fourth quarter of 2023. R&D expenses for the full year 2024 were $170.0 million , compared to $115.2 million for the prior year. General and administrative (G&A) expenses for the fourth quarter of 2024 were $24.1 million , compared to $14.2 million for the fourth quarter of 2023. G&A expenses for the full year 2024 were $77.1 million , compared to $50.6 million for the prior year. Net loss for the fourth quarter of 2024 was $19.2 million , compared to a net loss of $42.8 million for the fourth quarter of 2023. Net loss for the full year 2024 was $174.0 million , compared to a net loss of $152.6 million for the prior year. Net loss for the fourth quarter and full year 2024 included non-cash, share-based compensation expense of $8.6 million and $33.9 million , respectively. This compares to $7.2 million and $28.1 million for the same periods in 2023. As of December 31, 2024 , Kura had cash, cash equivalents and short-term investments of $727.4 million , including the upfront payment of $330.0 million from Kyowa Kirin, compared to $424.0 million as of December 31, 2023 . Based on our current plans, we believe our cash, cash equivalents and short-term investments as of December 31, 2024 will be sufficient to enable us to fund our current operating expenses into 2027, and combined with anticipated collaboration funding under the Kyowa Agreement, should support our ziftomenib AML program through commercialization in the 1L combination setting.
