SAN DIEGO, May 02, 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 first quarter 2024 financial results and provided a corporate update.

“Ziftomenib continues to demonstrate a best-in-class safety and efficacy profile as well as optimal pharmaceutical properties, which we believe will enable it to become a cornerstone of therapy in acute leukemias and beyond,” said Troy Wilson, Ph.D., J.D., President and Chief Executive Officer of Kura Oncology. “This belief is backed by increasing investigator enthusiasm, as evidenced by rapid enrollment across our ongoing ziftomenib studies, and further supported by the FDA’s decision to grant Breakthrough Therapy Designation (BTD) to ziftomenib, making it the first investigational treatment to be granted BTD for the treatment of NPM1-mutant acute myeloid leukemia (AML). In the near term, we look forward to completing enrollment in our registration-directed trial of ziftomenib in NPM1-mutant AML and working closely with FDA to bring this potentially innovative medicine to patients in urgent need of effective treatments.”

Recent Highlights

• Breakthrough Therapy Designation for ziftomenib in NPM1-mutant AML – Last month, the U.S. Food and Drug Administration (FDA) granted BTD to ziftomenib for the treatment of relapsed/refractory (R/R) NPM1-mutant AML. FDA granted BTD based on data from Kura’s ongoing KOMET-001 trial of ziftomenib in patients with R/R NPM1-mutant AML. BTD is awarded for a drug that treats a serious or life-threatening condition and may demonstrate substantial improvement on one or more clinically significant endpoints over available therapies.
  
  
• Registration-directed trial of ziftomenib in NPM1-mutant AML nearing completion – Kura remains on track to complete enrollment of 85 patients in its KOMET-001 registration-directed trial of ziftomenib in NPM1-mutant R/R AML by mid-2024. In the Phase 1 trial, ziftomenib demonstrated a 35% CR rate and 45% overall response rate in 20 heavily pretreated patients with NPM1-mutant AML treated at the recommended Phase 2 dose. NPM1-mutant AML accounts for approximately 30% of new AML cases annually and represents a disease of significant unmet need for which no approved targeted therapy exists.
  
  
• Positive preliminary combination data for ziftomenib in NPM1-mutant and KMT2A-rearranged AML – In January 2024, Kura reported preliminary data from the KOMET-007 dose-escalation trial of ziftomenib in combination with venetoclax/azacitidine or cytarabine/daunorubicin (7+3) in patients with NPM1-mutant or KMT2A-rearranged AML. As of the data cutoff on January 11, 2024, all five newly diagnosed patients treated with ziftomenib and 7+3 achieved a complete remission (CR) with full count recovery, for a CR rate of 100%. The overall response rate among the 15 R/R patients treated with ziftomenib and venetoclax/azacitidine was 53%. Continuous daily dosing of ziftomenib at 200 mg was well tolerated. No differentiation syndrome events of any grade were reported, and no dose-limiting toxicities, evidence of QTc prolongation, drug-drug interactions or additive myelosuppression were observed. As of the data cutoff, 16 of the first 20 patients remained on trial, including all 11 NPM1-mutant patients.
  
  
• Dose escalation continues in KOMET-007 combination trial of ziftomenib – To date, the 400 mg dose of ziftomenib has been cleared in three of the four cohorts in the KOMET-007 trial: 1) in combination with venetoclax/azacitidine in R/R NPM1-mutant AML, 2) in combination with venetoclax/azacitidine in R/R KMT2A-rearranged AML and 3) in combination with 7+3 in newly diagnosed adverse risk NPM1-mutant AML. Enrollment at the 600 mg dose is ongoing in all three cohorts. Enrollment continues at the 400 mg dose in combination with 7+3 in newly diagnosed adverse risk KMT2A-rearranged AML.
  
  
• First patients dosed in KOMET-008 combination trial of ziftomenib – In February, Kura began dosing patients in its KOMET-008 trial of ziftomenib in combination with additional standards of care, including the FLT3 inhibitor gilteritinib, FLAG-IDA or LDAC, for the treatment of R/R NPM1-mutant or KMT2A-rearranged AML. Preclinical data for ziftomenib in combination with FLT3 inhibitors demonstrate strong synergistic effects compared to either single agent alone. Roughly half of patients with R/R NPM1-mutant AML have co-occurring FLT3 mutations, and the prognosis for these patients is poor.
  
  
• First patients dosed with KO-2806 and cabozantinib in renal cell carcinoma – In March, Kura announced dosing of the first patient with KO-2806, the Company’s next-generation farnesyl transferase inhibitor (FTI), in combination with cabozantinib in clear cell renal cell carcinoma, just four months after dosing the first patients with KO-2806 as a monotherapy in the FIT-001 dose-escalation trial. The Company remains on track to dose the first patient in combination with adagrasib in KRAS^G12C-mutated non-small cell lung cancer by the middle of this year, as dose escalation of KO-2806 as a monotherapy continues in parallel.

Financial Results

• Research and development expenses for the first quarter of 2024 were $36.3 million, compared to $25.2 million for the first quarter of 2023.
  
  
• General and administrative expenses for the first quarter of 2024 were $18.2 million, compared to $11.4 million for the first quarter of 2023.

• As of March 31, 2024, Kura had cash, cash equivalents and short-term investments of $527 million, compared to $424 million as of December 31, 2023. This includes net proceeds of approximately $145.8 million from the Company’s private placement in January 2024.
  
  
• Based on its operating plan, management expects that cash, cash equivalents and short-term investments will fund current operations into 2027.
