Key Financial Metrics
The filing text does not provide specific financial metrics such as revenue, profit, cash flow, margins, debt, or liquidity.

Investors should refer to the Company's Quarterly Report on Form 10-Q for the period ended March 31, 2025, for financial data.
Material Changes and Clinical Results
The report details significant clinical progress for ziftomenib in the KOMET-007 study involving 71 response-evaluable patients with NPM1-mutant or KMT2A-rearranged AML:
- Composite Complete Remission (CRc): 92% (65/71) of patients achieved CRc (93% for NPM1-m; 89% for KMT2A-r).
- Complete Remission (CR): 80% (57/71) of patients achieved CR (84% for NPM1-m; 74% for KMT2A-r).
- MRD Negativity: 71% of NPM1-m patients and 88% of KMT2A-r patients achieved CR with minimal residual disease (MRD) negativity.
- Survival and Duration: Median overall survival (OS) had not been reached for either population. Median duration of CR was 25.6 weeks for KMT2A-r patients; not reached for NPM1-m patients.
- Study Continuation: 96% of NPM1-m patients and 88% of KMT2A-r patients remained alive and on study.
Guidance, Outlook, and Risks
Outlook and Next Steps: The Company expects to initiate KOMET-017, a randomized Phase 3 study covering both intensive and non-intensive chemotherapy arms, in the second half of 2025. A virtual investor event was held on June 18, 2025, to present these materials.
Safety Profile: The safety profile was consistent with prior data. Grade 3 or higher treatment-related adverse events occurring in >10% of patients included febrile neutropenia (15%), decreased platelet count (15%), anemia (11%), and decreased neutrophil count (11%). No dose-limiting toxicities or clinically meaningful QTc prolongation attributable to ziftomenib were observed.
Risks and Contingencies: The filing includes standard forward-looking statement disclaimers. Key risks include the potential for compounds to fail in later trials, regulatory approval uncertainties, reliance on third parties for clinical trials, and dependence on outside financing. Specific risks regarding the collaboration with Kyowa Kirin and the commercialization process are noted.
