(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.

In the MOTION Phase 3 study, ROMVIMZA met primary endpoint of improved objective response rate (ORR) compared to placebo and all key secondary endpoints with statistically significant and clinically meaningful improvements in quality-of-life measures, and demonstrated well-tolerated safety profile OSAKA, Japan & WALTHAM, MA, USA I February 14, 2025 I Ono Pharmaceutical Co., Ltd. (Headquarters: Osaka, Japan; President: Toichi Takino; “Ono”) announced that the U.S. Food and Drug Administration (FDA) has approved ROMVIMZA™ (vimseltinib), a kinase inhibitor, for adult patients with symptomatic tenosynovial giant cell tumor (TGCT) for which surgical resection will potentially cause worsening functional limitation or severe morbidity. The FDA previously granted Fast Track designation and Priority Review for ROMVIMZA, which was developed by Deciphera Pharmaceuticals, Inc. (“Deciphera”), a wholly owned subsidiary of Ono. “The approval of ROMVIMZA provides a new, much-needed, well-tolerated, and effective treatment option for people suffering from TGCT,” said Hans Gelderblom, M.D., Ph.D., Chair of the Department of Medical Oncology at Leiden University Medical Center. “TGCT adversely affects the lives of patients, causing significant pain, limited mobility, and stiffness. The MOTION Phase 3 study demonstrated ROMVIMZA’s ability to shrink tumors along with being the first well-tolerated agent to demonstrate significant improvement in a number of other important quality-of-life measures without any observed liver injury as seen with other approved TGCT treatment. ROMVIMZA is a differentiated treatment that has the potential to address the significant unmet needs of the TGCT community.” “The FDA approval of ROMVIMZA for TGCT is a crucial advancement for the TGCT community and we believe ROMVIMZA has the potential to become the new standard of care for people with TGCT for which surgical resection will potentially cause worsening functional limitation or severe morbidity. This is also an important milestone for our organization, as it is the second approved therapy discovered using Deciphera’s proprietary switch-control kinase inhibitor platform,” said Ryota Udagawa, President and Chief Executive Officer of Deciphera Pharmaceuticals. “I’d like to extend my gratitude to the patients, families, caregivers, and healthcare providers who contributed to the success in ROMVIMZA’s clinical studies. Their commitment, along with the dedication of the Deciphera and Ono teams, enabled us to advance this impactful new treatment, which we look forward to delivering to patients.” TGCT is a rare, non-malignant tumor that forms within or near joints. TGCT arises from the dysregulation of the CSF1 gene, resulting in an overproduction of CSF1. If left untreated or if the tumor repeatedly recurs, it can lead to damage and degeneration in the affected joint and surrounding tissues, potentially causing significant disability. The FDA approval was based on the efficacy and safety results from the pivotal Phase 3 MOTION study of ROMVIMZA in patients with TGCT not amenable to surgery with no prior anti-CSF1/CSF1R therapy (prior therapy with imatinib or nilotinib allowed), compared to placebo, as well as the Phase 1/2 study of ROMVIMZA. In MOTION, ROMVIMZA demonstrated a statistically significant and clinically meaningful ORR at Week 25 in the intent-to-treat (ITT) population, as assessed by blinded independent radiologic review (IRR) per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1), versus placebo (40% in ROMVIMZA arm vs 0% in placebo arm, p <0.0001). The primary endpoint was supported by statistically significant and clinically meaningful improvements in active range of motion, patient-reported physical functioning, and patient-reported pain observed in the vimseltinib arm compared to the placebo arm at week 25. The safety profile of ROMVIMZA is manageable and consistent with results previously disclosed in the Phase 1/2 clinical trial. Deciphera Pharmaceuticals plans to make ROMVIMZA commercially available in the U.S. next week. Learn more at www.ROMVIMZA.com . In July of 2024, the Company announced the marketing authorization application (MAA) for ROMVIMZA for the treatment of patients with TGCT was accepted and is under review by the European Medicines Agency (EMA). Deciphera is committed to supporting TGCT patients and providers in navigating coverage and access to ROMVIMZA. As part of that commitment, Deciphera AccessPoint TM , a patient support program, is available to provide comprehensive access and financial assistance programs for eligible patients. For more information, visit DecipheraAccessPoint.com or call 1-833-4DACCES (1-833-432-2237), Monday-Friday, 8:00 AM to 8:00 PM Eastern Time (ET). About MOTION Study The MOTION study is a two-part, randomized, double-blind, placebo-controlled Phase 3 clinical study to assess the efficacy and safety of vimseltinib in patients with TGCT not amenable to surgery with no prior anti-CSF1/CSF1R therapy (prior therapy with imatinib or nilotinib allowed). The primary endpoint of the study is an objective response rate (ORR) at Week 25 in the intent-to-treat (ITT) population, as assessed by blinded independent radiologic review (IRR) per using Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1), versus placebo. The secondary endpoints include ORR per tumor volume score (TVS), active range of motion (ROM), physical function, stiffness, quality of life, and pain, all assessed at Week 25. This study consists of two Parts. In Part 1, patients were randomized to receive either vimseltinib or placebo for 24 weeks. In Part 2, patients randomized to placebo in Part 1 have the option to receive vimseltinib, and all patients receive vimseltinib for a long-term period in an open-label setting. ROMVIMZA (vimseltinib) capsules INDICATIONS AND USAGE ROMVIMZA is indicated for treatment of adult patients with symptomatic tenosynovial giant cell tumor (TGCT) for which surgical resection will potentially cause worsening functional limitation or severe morbidity. IMPORTANT SAFETY INFORMATION WARNINGS AND PRECAUTIONS Hepatotoxicity Embryo-Fetal Toxicity: Allergic Reactions to FD&C Yellow No.5 (Tartrazine) and No. 6 (Sunset Yellow FCF): Increased Creatinine without Affecting Renal Function: Adverse Reactions: The most common (≥20%) adverse reactions, including laboratory abnormalities that occurred in patients receiving ROMVIMZA were increased AST, periorbital edema, fatigue, rash, increased cholesterol, peripheral edema, face edema, decreased neutrophils, decreased leukocytes, pruritus, and increased ALT. Drug Interactions: Lactation: Advise females not to breastfeed during treatment with ROMVIMZA. Please see the accompanying full Prescribing Information . About Tenosynovial Giant Cell Tumor (TGCT) TGCT is a rare disease caused by a translocation in colony-stimulating factor 1 (CSF1) gene resulting in overexpression of CSF1 and recruitment of colony-stimulating factor 1 receptor (CSF1R)-positive inflammatory cells into the lesion. TGCT is a rare, non-malignant tumor that develops inside or near joints. TGCT is caused by dysregulation of the CSF1 gene leading to overproduction of CSF1. TGCT is also known as giant cell tumor of the tendon sheath (GCT-TS) or pigmented villonodular synovitis (PVNS), a diffuse-type of TGCT. Although non-malignant, these tumors can grow and cause damage to surrounding tissues and structures inducing pain, swelling, and limitation of movement of the joint. Surgery is the main treatment option; however, these tumors tend to recur, particularly in diffuse-type TGCT. If untreated or if the tumor continually recurs, damage and degeneration may occur in the affected joint and surrounding tissues, which may cause significant disability. For a subset of patients, surgical resection will potentially cause worsening functional limitation or severe morbidity, systemic treatment options are limited and a new therapeutic option for TGCT is needed.
