SAN DIEGO, Feb. 24, 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 fourth quarter and full year 2021 financial results and provided a corporate update.

"We have made meaningful advancements across our programs during the past year, and we begin 2022 with significant momentum, resources and enthusiasm," said Troy Wilson, Ph.D., J.D., President and Chief Executive Officer of Kura Oncology. "By mid-2022, we expect to have three independent drug development programs with potential to create value in both solid and liquid tumor indications with high unmet need. We anticipate meaningful data catalysts for each of these programs in the next six to 24 months, beginning with top-line data from our KOMET-001 Phase 1b study. And we approach these catalysts from a position of strength, with an experienced team and more than $500 million in cash."

Recent Highlights

Patient enrollment continues in KOMET-001 Phase 1b study of ziftomenib (KO-539) – In January 2022, Kura received authorization from the U.S. Food and Drug Administration (FDA) to proceed with its KOMET-001 trial of ziftomenib (formerly KO-539) in patients with relapsed or refractory acute myeloid leukemia (AML), following agreement with the FDA on an enhanced mitigation strategy for differentiation syndrome. Differentiation syndrome is known to be an on-target effect associated with a number of therapeutic agents, including menin inhibitors, which may induce differentiation of leukemic blasts. Patients already enrolled in the Phase 1b expansion cohorts were eligible to remain on study during the partial clinical hold and enrollment of new patients has resumed.
Multiple milestones and data readouts from KOMET-001 expected in 2022 – Kura expects to complete enrollment of 24 patients in the Phase 1b study of ziftomenib by the second quarter of 2022, after which it will assess the patients in each expansion cohort for safety and tolerability, pharmacokinetics and exposure, as well as efficacy. The Company expects to identify the recommended Phase 2 dose for ziftomenib and report top-line data from the Phase 1b study by the third quarter of 2022, with updated data from KOMET-001 reserved for a medical meeting in the fourth quarter of 2022. Meanwhile, Kura continues to add sites in the U.S. and Europe in anticipation of the subsequent Phase 2 registration-enabling portion of KOMET-001.
First patients dosed in Phase 1/2 trial of tipifarnib plus alpelisib in HNSCC – Last year, Kura announced a clinical collaboration with Novartis to evaluate the combination of tipifarnib and the PI3Kα inhibitor alpelisib in patients with head and neck squamous cell carcinoma (HNSCC). The Company believes this combination has the potential to increase the total addressable population for tipifarnib to as much as 50% of patients with HNSCC. In December 2021, the first patient was dosed in a Phase 1/2 clinical trial (KURRENT) of tipifarnib in combination with alpelisib. The initial cohort includes patients who have PIK3CA-dependent HNSCC. The Company expects to initiate an HRAS overexpression cohort in KURRENT by the third quarter of 2022.
Preclinical data supporting next-generation FTI program at AACR – Kura's next-generation farnesyl transferase inhibitor (FTI) program is designed to target novel farnesylated targets and address large solid tumor indications of high unmet need through combination regimens, with a focus on delaying the onset of drug resistance. An abstract from one of the Company's academic collaborators, with preclinical data supporting the first opportunity in non-small cell lung cancer (NSCLC), has been accepted for presentation at the upcoming American Association for Cancer Research Annual Meeting in April 2022. Kura plans to perform initial clinical evaluation with tipifarnib in NSCLC while continuing its IND-enabling studies of KO-2806, the lead development candidate in the Company's next-generation FTI program.

Financial Results

Research and development expenses for the fourth quarter of 2021 were $21.0 million, compared to $17.5 million for the fourth quarter of 2020. Research and development expenses for the full year 2021 were $84.7 million, compared to $60.4 million for the prior year.
General and administrative expenses for the fourth quarter of 2021 were $12.1 million, compared to $8.8 million for the fourth quarter of 2020. General and administrative expenses for the full year 2021 were $46.5 million, compared to $31.5 million for the prior year.
Net loss for the fourth quarter of 2021 was $32.7 million, compared to a net loss of $26.2 million for the fourth quarter of 2020. Net loss for the full year 2021 was $130.5 million, compared to a net loss of $89.6 million for the prior year. Net loss for the fourth quarter and full year 2021 included non-cash share-based compensation expense of $6.4 million and $23.6 million, respectively, $3.7 million and $12.8 million for the same periods in 2020.
Cash, cash equivalents and short-term investments totaled $518.0 million as of December 31, 2021, compared with $633.3 million as of December 31, 2020. Management expects that current cash, cash equivalents and short-term investments will be sufficient to fund current operations into 2024.

About Kura Oncology

Kura Oncology is a clinical-stage biopharmaceutical company committed to realizing the promise of precision medicines for the treatment of cancer. The Company's pipeline consists of small molecule drug candidates that target cancer signaling pathways. Ziftomenib (KO-539), a potent and selective menin inhibitor, is currently in a Phase 1b clinical trial (KOMET-001) for patients with relapsed/refractory AML, including patients with NPM1 mutations or KMT2A rearrangements. Tipifarnib, a potent, selective and orally bioavailable farnesyl transferase inhibitor (FTI), has received Breakthrough Therapy Designation for the treatment of patients with HRAS mutant HNSCC and is currently in a registration-directed trial (AIM-HN) in patients with this devastating disease. In addition, Kura is conducting a Phase 1/2 trial (KURRENT) of tipifarnib in combination with the PI3Kα inhibitor alpelisib to address larger genetic subsets of HNSCC patients, including those whose tumors are dependent on HRAS and/or PI3Kα pathways. The Company is also developing KO-2806, a next-generation FTI, which is intended to target innovative biology and larger oncology indications through rational combinations.
