Item 2.02 | Results of Operations and Financial Condition. |
On January 30, 2024, Kura Oncology, Inc. (the “Company”) announced that its preliminary unaudited cash, cash equivalents and short-term investments as of December 31, 2023 were approximately $424 million and that the net proceeds from its recent private placement that closed on January 26, 2024 were approximately $146 million.
The preliminary unaudited cash position discussed above is subject to the completion of financial closing procedures and other developments that may arise between now and the time the financial results for the fourth quarter of 2023 are finalized, as well as the completion of the audit of the 2023 financial statements. Therefore, actual results may differ materially from these estimates. In addition, the above estimates do not present all information necessary for an understanding of the Company’s financial condition as of December 31, 2023.
The information contained in this Current Report on Form 8-K under Item 2.02 is being furnished and shall not be deemed to be “filed” for the purposes of Section 18 of the Securities and Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section and will not be incorporated by reference into any filing by the Company under the Securities Act of 1933, as amended, or the Exchange Act, unless specifically identified as being incorporated therein by reference.
On January 30, 2024, the Company reported preliminary clinical data from the first 20 patients in KOMET-007, a Phase 1 dose-escalation trial of the Company’s potent and selective menin inhibitor, ziftomenib, in combination with standards of care, including cytarabine/daunorubicin (“7+3”) and venetoclax/azacitidine (“ven/aza”), in patients with NPM1-mutant (“NPM1-m”) and KMT2A-rearranged (“KMT2A-r”) acute myeloid leukemia (“AML”).
The first 20 patients were enrolled in KOMET-007 between July 2023 and November 2023, including five newly diagnosed patients with adverse risk1 NPM1-m or KMT2A-r AML and 15 patients with refractory/relapsed (“R/R”) NPM1-m or KMT2A-r AML.
Continuous daily dosing of ziftomenib at 200 mg QD has been well tolerated and the safety profile is consistent with features of underlying disease and backbone therapies. 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 on January 11, 2024, all newly diagnosed patients treated with ziftomenib and 7+3 achieved a complete remission (“CR”) with full count recovery, for a CR rate of 100% (5/5), including four patients with NPM1-m AML and one patient with KMT2A-r AML.
The overall response rate (“ORR”) among R/R patients treated with ziftomenib and ven/aza was 53% (8/15). Among all patients treated with ziftomenib and ven/aza, 40% (6/15) received prior treatment with a menin inhibitor. The CR/CRh2 rate in patients who were menin inhibitor naïve was 56% (5/9), including 60% (3/5) in patients with NPM1-m AML and 50% (2/4) in patients with KMT2A-r AML. The ORR in patients who received prior venetoclax was 40% (4/10), including 60% (3/5) in patients with NPM1-m AML.
As of the data cutoff, 80% (16/20) of patients remain on trial, including 100% (11/11) of all NPM1-m patients.
The 200 mg dose of ziftomenib has been cleared in the R/R ven/aza cohorts and enrollment at the 400 mg dose is ongoing. Upon determination of a recommended Phase 2 dose, the Company plans to initiate a Phase 1b dose validation/expansion in combination with ven/aza in newly diagnosed patients with NPM1-m (without adverse risk) or KMT2A-r AML.
