SAN DIEGO, Nov. 03, 2022 (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 2022 financial results and provided a corporate update.

"We are very proud to announce that our abstract reporting updated data from the KOMET-001 trial of ziftomenib has been accepted for oral presentation at the upcoming American Society of Hematology (ASH) Annual Meeting in December," said Troy Wilson, Ph.D., J.D., President and Chief Executive Officer of Kura Oncology. "We continue to have strong conviction in ziftomenib and its potential to be a best-in-class menin inhibitor. Our confidence is supported by a growing body of clinical data, and we look forward to sharing a comprehensive update on the program at ASH."

"Earlier this morning, we also announced a $25 million equity investment from Bristol Myers Squibb and a $125 million term loan facility from Hercules Capital," Dr. Wilson continued. "If the term loan facility is fully drawn, proceeds from these two transactions, together with our existing cash, are expected to fund our current operating plan into 2026, enabling us to advance ziftomenib as well as our farnesyl transferase inhibitor programs through important, clinical-stage inflection points that we believe will create meaningful value for patients and shareholders."

Recent Highlights

Updated data from KOMET-001 accepted for oral presentation at ASH – An abstract reporting updated data from the KOMET-001 trial of ziftomenib has been accepted for oral presentation at the ASH Annual Meeting on December 10, 2022. The abstract, which will be published on the ASH website later today, highlights the encouraging safety profile and clinical activity of ziftomenib in patients with relapsed/refractory acute myeloid leukemia (AML). It includes 30 all-comer AML patients from the Phase 1a dose-escalation portion of the trial and 24 NPM1-mutant or KMT2A-rearranged AML patients from the Phase 1b portion – 12 patients at 200 mg and 12 patients at 600 mg.

Additional 18 patients enrolled in KOMET-001 Phase 1b extension – Kura enrolled an additional 18 patients with NPM1-mutant or KMT2A-rearranged relapsed/refractory AML in a Phase 1b extension as the Company prepares to transition into the Phase 2 registration-directed portion of the KOMET-001 trial and initiate a series of combination studies in the relapsed and frontline settings, pending FDA review of the recommended Phase 2 dose (RP2D) and protocols. Kura anticipates sharing a more mature dataset, including preliminary data from the additional 18 patients in the Phase 1b extension, during its oral presentation at ASH.

Preliminary proof of mechanism of tipifarnib plus alpelisib in HNSCC – Last week, at the EORTC-NCI-AACR Molecular Targets and Cancer Therapeutics Symposium, Kura reported the first demonstration that the combination of tipifarnib and alpelisib can induce a durable clinical response in PIK3CA-dependent head and neck squamous cell carcinoma (HNSCC). A patient with stage III squamous cell carcinoma of the tonsil with a PIK3CA mutation and HRAS overexpression has achieved a durable partial remission in KURRENT-HN. As of mid-September, the patient has experienced an 84% reduction in target lesions and continued on-study for more than 27 weeks. Treatment-related adverse events in KURRENT-HN have been consistent with the known safety profiles of each drug and are manageable, with no dose-limiting toxicities reported to date.

AIM-HN registration-directed trial closed to further enrollment – Kura continues to observe evidence of meaningful clinical activity in its AIM-HN registration-directed trial of tipifarnib as a monotherapy in recurrent and metastatic HRAS mutant HNSCC but has elected to close the trial to further enrollment due to significant feasibility challenges. The Company is currently evaluating the best way to harvest and use the clinical data from AIM-HN, along the with the data from the RUN-HN trial, which formed the basis of the Breakthrough Therapy Designation for tipifarnib, to inform future development of the program. Given the significant overlap between patients with HRAS overexpression and mutation, HRAS mutant HNSCC patients in the U.S. may be eligible to enroll in the KURRENT-HN study.

Initiation of KURRENT-LUNG trial of tipifarnib plus osimertinib – Kura has initiated a Phase 1 KURRENT-LUNG trial of tipifarnib in combination with osimertinib in EGFR-mutated non-small cell lung cancer (NSCLC) and expects to dose the first patient this quarter. Preclinical data, generated through a collaboration with INSERM (the French National Institute of Health and Medical Research), support the potential of tipifarnib to prevent emergence of resistance to osimertinib in EGFR-mutant NSCLC. The Company intends to perform initial clinical evaluation with tipifarnib in combination with osimertinib while advancing its next-generation FTI, KO-2806, through investigational new drug (IND)-enabling studies.

$25 million equity investment from Bristol Myers Squibb – Kura has agreed to sell 1,370,171 shares to Bristol Myers Squibb at a price of $18.25 per share for gross proceeds of $25 million. In connection with the equity investment, Bristol Myers Squibb will appoint a member to Kura's Global Steering Committee. The equity investment further strengthens the relationship between the two organizations and enables Bristol Myers Squibb, a leader in the discovery and development of transformational cancer treatments, to provide valuable strategic input into Kura's global development strategy.

$125 million term loan facility from Hercules Capital – Under the terms of the loan agreement, $10 million will be drawn immediately after closing and an additional $15 million is immediately available to Kura at its sole discretion. Kura may draw an additional $75 million in two separate tranches upon achievement of near-term clinical milestones. An additional $25 million may be drawn in a fourth tranche, subject to the approval of Hercules Capital. The term loan facility augments Kura's already strong balance sheet and gives the Company significant financial strength and flexibility to invest across its three programs to drive meaningful value for both patients and shareholders.

Financial Results

Research and development expenses for the third quarter of 2022 were $25.0 million, compared to $22.4 million for the third quarter of 2021. The increase in R&D expenses was primarily due to increases in personnel costs and discovery stage programs.

General and administrative expenses for the third quarter of 2022 were $11.6 million, compared to $11.3 million for the third quarter of 2021. The increase in G&A expenses was primarily due to increases in personnel costs.

Net loss for the third quarter of 2022 was $35.5 million, compared to a net loss of $33.4 million for the third quarter of 2021. This included non-cash share-based compensation expense of $6.4 million, compared to $6.1 million for the same period in 2021.

Cash, cash equivalents and short-term investments totaled $427.8 million as of September 30, 2022, compared with $518.0 million as of December 31, 2021.

As adjusted for the $25 million equity investment from Bristol Myers Squibb and the $10 million initial draw from the Hercules term loan facility, Kura had, on a pro forma basis, $462.8 million in cash, cash equivalents and short-term investments at September 30, 2022.

Management believes that cash, cash equivalents and short-term investments, plus cash from the term loan facility from Hercules, if fully drawn, will be sufficient to fund its current operating plan into 2026.
