Management Comments

• We are a biopharmaceutical company committed to realizing the promise of precision medicines for the treatment of cancer.
• 2025 was a pivotal year for our company.
• KOMZIFTI is the first and only menin inhibitor approved by the FDA for once-daily oral administration.
• We believe that KOMZIFTI is differentiated from other menin inhibitors on the four pillars of efficacy, safety, compatibility and simplicity, and our market research indicates that this differentiated profile aligns with the priorities of physicians, pharmacists and care teams who treat patients with AML as well as with third-party payors, including commercial insurers and government healthcare programs.
• Our strategy is to discover, acquire, develop and commercialize innovative agents in oncology indications and other diseases with significant unmet medical need and attractive commercial potential.
• A central tenet of our strategy is to make drugs that make good drugs better.
• We believe that menin inhibition may impact insulin deficiency and insulin resistance by restoring beta-cell mass.
• We believe these characteristics support development of darlifarnib across multiple oncology indications.
• We believe our employees are the driving force to achieving our business goals and growth strategy and we continuously monitor our demand for capable and talented people to support our mission.
• We believe that our cash, cash equivalents and short-term investments as of December 31, 2025 will be sufficient to fund our current operating plan into the fourth quarter of 2027.
• In addition, when combined with the anticipated $180.0 million in payments under the Kyowa License Agreement, we expect to have sufficient capital to advance our ziftomenib AML program through the first topline results from KOMET-017, anticipated in 2028.

Industry Context

StockSavvy.ai notes that Kura Oncology's FDA approval of KOMZIFTI positions it as a key player in the rapidly evolving precision oncology market, specifically targeting NPM1-mutated AML. The company's strategy to develop combination therapies and expand into frontline AML aligns with broader industry trends focusing on enhancing efficacy and durability of responses. The entry into the menin inhibitor space with a differentiated product (once-daily, no QTc Black Box warning) places it in direct competition with Syndax's revumenib (REVUFORJ), another FDA-approved menin inhibitor. Kura's exploration of FTIs and next-generation menin inhibitors for solid tumors and cardiometabolic disorders demonstrates a diversified pipeline approach, aiming to capture multiple market opportunities beyond its initial AML indication, a common strategy among growing biopharmaceutical firms seeking to de-risk their portfolios and maximize therapeutic impact.

Comparison to Industry Standards

• KOMZIFTI's efficacy (CR+CRh rate of 21.4%) in relapsed or refractory NPM1-mutated AML from KOMET-001 trial provides a specific benchmark for menin inhibitors in this indication.
• KOMZIFTI's safety profile, particularly the absence of a Black Box warning for QTc interval prolongation, differentiates it favorably from Syndax's revumenib, the other FDA-approved menin inhibitor, which does carry such a warning.
• The high rates of durable morphologic complete responses (CRc 86%; CR 73%) and molecular MRD negativity (68%) for ziftomenib in combination with venetoclax and azacitidine in newly diagnosed NPM1-mutated AML (KOMET-007 trial) are strong indicators compared to historical outcomes with venetoclax and azacitidine alone.
• The CRc rate of 93% for NPM1-mutated AML and 89% for KMT2A-rearranged AML with ziftomenib + 7+3 in newly diagnosed patients (KOMET-007 trial) represent high response rates for these challenging patient populations.
• Market access decisions for KOMZIFTI, with 80% of private payors establishing coverage policies within 90 days of approval and some requiring KOMZIFTI first, surpass typical benchmarks for new drug launches in terms of speed and breadth of coverage.

Corporate Governance

Legal Proceedings

• The company is not currently a party to, nor is its property the subject of, any material legal proceedings.

Related Party Transactions

• In December 2014, the company entered into a license agreement with the University of Michigan, which was most recently amended in August 2017, granting exclusive worldwide rights under certain patent rights to compounds in the menin-KMT2A program. The company issued 79,113 shares of common stock to the University of Michigan in March 2015 as a result of a private placement.
