Overview

We are a biopharmaceutical company committed to realizing the promise of precision medicines for the treatment of cancer. Since our founding in 2014, we have transformed from a research and development company to a fully-integrated commercial-stage organization with a diversified pipeline of product candidates. Our pipeline consists of small molecules designed to target cancer signaling pathways and address significant unmet needs in oncology and hematology.

Our Product and Pipeline

KOMZIFTI® (ziftomenib)

On November 13, 2025, the U.S. Food and Drug Administration, or FDA, approved our new drug application, or NDA, for ziftomenib, which is being marketed in the United States under the trade name KOMZIFTI, for the treatment of adults with relapsed or refractory acute myeloid leukemia, or AML, with a susceptible nucleophosmin 1, or NPM1, mutation who have no satisfactory alternative treatment options. KOMZIFTI is the first and only menin inhibitor approved by the FDA for once-daily oral administration. The FDA previously granted Breakthrough Therapy, Fast Track and Orphan Drug Designations as well as Priority Review to ziftomenib.

FDA approval of our NDA for KOMZIFTI was based upon positive data from our KOMET-001 trial, a global Phase 1/2 trial that evaluated KOMZIFTI’s safety and efficacy in 112 patients with relapsed or refractory NPM1-mutated AML.

We believe that KOMZIFTI is differentiated from other menin inhibitors based on its 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.

Efficacy: The rate of complete remission, or CR, plus CR with partial hematologic recovery, or CRh, in the KOMET-001 trial was 21.4% (95% CI: 14.2, 30.2). The median duration of CR+CRh was five months (95% CI: 1.9, 8.1) and the

14

median time to first response in patients who achieved a CR or CRh was 2.7 months (range: 0.9 to 15 months). 88% of patients who achieved CR or CRh did so within six months of initiating KOMZIFTI. These data from the Prescribing Information for KOMZIFTI are generally consistent with the full results of the KOMET-001 trial published in the Journal of Clinical Oncology in September 2025.

Safety: KOMZIFTI demonstrated a manageable safety profile in the KOMET-001 trial, with most reported adverse events being Grade 1 or Grade 2. The most common adverse reactions, including laboratory abnormalities, reported in 20% or more of patients were aspartate aminotransferase increased, infection without an identified pathogen, potassium decreased, albumin decreased, alanine aminotransferase increased, sodium decreased, creatinine increased, alkaline phosphatase increased, hemorrhage, diarrhea, nausea, fatigue, edema, bacterial infection, musculoskeletal pain, bilirubin increased, potassium increased, differentiation syndrome, or DS, pruritus, febrile neutropenia and transaminases increased. Notably, no Grade 4 or Grade 5 QTc interval prolongation was reported. 12% of patients experienced QTc interval prolongation of ≤ Grade 3 and, of the 70 patients 65 years of age or older, 10% experienced QTc interval prolongation of any cause.

The Prescribing Information for KOMZIFTI includes a Black Box warning for DS, a well-studied mechanism-based risk in drugs that restore differentiation, and clear dose-modification guidelines for physicians to follow when DS is suspected. Unlike the other FDA-approved menin inhibitor, KOMZIFTI does not have a Black Box warning for QTc interval prolongations or Torsades de Pointes.

Compatibility: In contrast with other therapies that require dose adjustments when co-administered with anti-infective medications or other strong or moderate CYP3A4 inhibitors or inducers, KOMZIFTI can be co-administered without dose modification, offering predictability to physicians and reducing complexity and risk.

Simplicity: KOMZIFTI is the first and only menin inhibitor approved by the FDA for once-daily oral administration. KOMZIFTI’s once-daily dosing is beneficial to patients who are often elderly and on several concomitant medications.

We initiated commercial sales of KOMZIFTI in the United States on November 21, 2025. Under the terms of the collaboration and license agreement that we entered into with Kyowa Kirin Co., Ltd. and Kyowa Kirin, Inc., or together Kyowa Kirin, in November 2024, or the Kyowa License Agreement, we lead commercial strategy for and are responsible for manufacturing KOMZIFTI in the United States. We and Kyowa Kirin are jointly performing commercialization and medical affairs activities in accordance with a co-created U.S. territory commercialization plan and the co-promotion and medical affairs agreement that we entered into with Kyowa Kirin, Inc. in June 2025, or the Kyowa Co-Promotion Agreement. We record all U.S. sales of KOMZIFTI, and we and Kyowa Kirin share equally the profits and losses from the commercialization activities in the United States. Outside the United States, Kyowa Kirin is responsible for commercial strategy and for commercializing ziftomenib and booking sales.

For the six months ended June 30, 2026, we achieved $14.9 million in KOMZIFTI net product revenue.

Following the FDA’s November 2025 approval of KOMZIFTI, we announced that KOMZIFTI was added to the National Comprehensive Cancer Network®, or NCCN, Clinical Practice Guidelines in Oncology (NCCN Guidelines®) as a Category 2A recommended treatment option for adults with relapsed or refractory NPM1-mutated AML.

In addition, following FDA approval, we submitted patent information to our NDA regarding eight granted U.S. patents that claim the drug substance, drug product and/or methods of treatment for KOMZIFTI. These patents, which have been added to the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations, commonly known as the Orange Book, for KOMZIFTI, include two recently granted patents that share a base expiration date of July 16, 2044. We have submitted applications for patent term extension for two U.S. granted patents to the U.S. Patent and Trademark Office, or U.S. PTO, along with our assessment of the duration of applicable extensions.

We have made significant progress in securing insurance coverage and reimbursement for KOMZIFTI in the United States. We have secured parity coverage for more than 95% of covered lives in the United States. Among private payors, several published policies require patients with relapsed or refractory NPM1-mutated AML to step through KOMZIFTI first before receiving other available menin inhibitors.

Menin Inhibitor Development Programs

Clinical Development of Ziftomenib in AML

Together with Kyowa Kirin, we are advancing the global clinical development of ziftomenib across the treatment continuum for AML, including in combinations with standards of care for AML and in patients with frontline and relapsed or refractory disease.

Ziftomenib Combinations with Standards of Care for AML

Newly Diagnosed AML

In September 2025, we initiated KOMET-017, a single protocol comprised of two independent, global, randomized, double-blind, placebo-controlled Phase 3 trials to evaluate ziftomenib in combination with both intensive and non-intensive regimens in patients with newly diagnosed NPM1-mutated or KMT2A-rearranged AML. The KOMET-017 protocol was informed by the clinical data and findings generated in our Phase 1 KOMET-007 trial. The single protocol design of KOMET-017 has streamlined the study start-up process, resulting in site activation at a pace that has exceeded our expectations. Patients have been dosed in both trials and enrollment continues to progress.

Combination with Non-Intensive Chemotherapy (Venetoclax/Azacitidine) in NPM1-Mutated AML

The registrational KOMET-017-NIC (Non-Intensive Chemotherapy) trial is evaluating the combination of ziftomenib with venetoclax plus azacitidine in patients with newly diagnosed NPM1-mutated AML who are unfit to receive intensive chemotherapy. The KOMET-017-NIC trial will assess CR and overall survival, or OS, as dual-primary endpoints to support potential U.S. accelerated approval and full approval, respectively. Patients in this trial are randomized to receive ziftomenib or placebo, in combination with venetoclax and azacitidine.

We previously evaluated ziftomenib in combination with venetoclax and azacitidine in patients with newly diagnosed NPM1-mutated AML in the Phase 1 KOMET-007 trial, and we delivered an oral presentation of preliminary data from the Phase 1b expansion cohort evaluating this regimen at the 67th Annual Meeting of the American Society of Hematology, or ASH, in December 2025. As presented at ASH, 40 patients with newly diagnosed NPM1-mutated AML had been enrolled in the cohort as of the September 24, 20

These patents, which have been added to the Orange Book for KOMZIFTI, include two recently granted patents that share a base expiration date of July 16, 2044.

Market access decisions have enabled KOMZIFTI to be available to covered lives in the United States within the first 90 days after FDA approval. At least 80% of private payors have now established published coverage policies to cover KOMZIFTI for the indicated population, all aligned with the label with no additional restrictions. The timing of coverage decisions by payors, including many state Medicaid programs and private payors, have surpassed benchmarks. Among private payors, some published policies now require patients with relapsed or refractory NPM1-mutated AML to step through KOMZIFTI first before receiving other available menin inhibitors.

The KOMET-017-NIC trial will assess CR and OS as dual-primary endpoints to support potential U.S. accelerated approval and full approval, respectively. Patients in this trial are randomized to receive ziftomenib or placebo, in combination with venetoclax and azacitidine.

We previously evaluated ziftomenib in combination with venetoclax and azacitidine in patients with newly diagnosed NPM1-mutated AML in the Phase 1 KOMET-007 trial, and we delivered an oral presentation of preliminary data from the Phase 1b expansion cohort evaluating this regimen at the 67th ASH Annual Meeting in December 2025. As presented at ASH, 40 patients with newly diagnosed NPM1-mutated AML had been enrolled in the cohort as of the September 24, 2025 data cutoff date, 58% (23/40) of whom had an ECOG performance status of two and 37 of whom were response evaluable. High rates of durable morphologic complete responses (CRc 86%; CR 73%) were observed, with 68% of CRc responders having achieved molecular MRD negativity by central NGS.

As of the data cutoff for the ASH presentation, median duration of CR and median OS were not reached at median follow-up of 26.1 weeks (range 1.6–54.1). 68% of patients remained alive and on treatment or in long-term follow-up as of the data cutoff. The triplet combination was generally well tolerated, with a safety profile consistent with that reported for venetoclax and azacitidine alone. Rates of ziftomenib-related myelosuppression were low, and the median times to neutrophil and platelet recovery were also consistent with those expected for venetoclax and azacitidine alone. One case each of Grade 2 DS and Grade 3 investigator-assessed QTc prolongation were successfully managed without treatment discontinuation.

Combination with Intensive Chemotherapy (7+3) in NPM1-Mutated or KMT2A-Rearranged AML

The registrational KOMET-017-IC (Intensive Chemotherapy) trial is evaluating the combination of ziftomenib with induction chemotherapy (7+3) in patients with newly diagnosed NPM1-mutated or KMT2A-rearranged AML. Patients in this trial are randomized to receive ziftomenib or placebo in combination with standard induction, consolidation chemotherapy and post-consolidation maintenance. The KOMET-017-IC trial will assess MRD-negative CR and EFS as dual-primary endpoints to support potential U.S. accelerated approval and full approval, respectively. Based on our current assumptions, we anticipate topline results from the MRD-negative CR accelerated endpoint in the intensive chemotherapy setting in 2028.

We previously evaluated ziftomenib in combination with 7+3 in patients with newly diagnosed NPM1-mutated or KMT2A-rearranged adverse risk AML in the KOMET-007 trial. In June 2025, we presented positive data at the European Hematology Association Congress from the KOMET-007 Phase 1b cohort evaluating this regimen. Ziftomenib dosed once daily at 600 mg in combination with 7+3 demonstrated robust and evolving clinical activity
