SAN DIEGO, Nov. 10, 2026 (GLOBE NEWSWIRE) -- Kura Oncology, Inc. (Nasdaq: KURA), a biopharmaceutical company focused on precision medicines for cancer, today reported third quarter 2026 financial results and provided a corporate update.

“KOMZIFTI delivered strong commercial performance this quarter, with 53% sequential revenue growth, a 30% increase in new patients starts, and continued majority share of new patient starts,” said Troy Wilson, Ph.D., J.D., President and Chief Executive Officer of Kura Oncology. “We believe these results demonstrate the growing commercial potential of KOMZIFTI and provide a strong foundation as we advance ziftomenib into the substantially larger frontline AML opportunity. We have also reached FDA alignment on our planned registrational study of darlifarnib in HRAS-mutant salivary gland cancer, providing a potential path to our second product approval as we continue to pursue broader opportunities with combinations in solid tumors. With a strengthened financial position, we believe we are well positioned to execute on these priorities and build two differentiated precision oncology franchises.”

KOMZIFTI 3Q 2026 Commercial Performance

• $13.9 million in net product revenue, a 53% increase from 2Q 2026
  
  
• Approximately 150 new patient starts (NPS), a 30% increase from 2Q 2026
  
  
• More than 420 total prescriptions (TRx), including repeat prescriptions, a 65% increase from 2Q 2026
  
  
• KOMZIFTI maintained a majority share of NPS in the relapsed or refractory (R/R) NPM1-m AML menin inhibitor class
  
  

Advancing Two Precision Oncology Franchises

• Advancing the Phase 3 KOMET-017 frontline registrational program with ziftomenib-based combinations in newly diagnosed AML; site activation and patient enrollment continue across studies for patients eligible for intensive and non-intensive chemotherapy.
  
  
• Alignment reached with the U.S. Food and Drug Administration (FDA) on the design of a planned darlifarnib single-arm monotherapy registrational study in patients with HRAS-mutant salivary gland cancer (SGC) to support potential approval.
  
  
• An August publication in Blood described the discovery and preclinical characterization of ziftomenib, including its potency, selectivity, menin binding properties, and activity against certain resistance-associated mutations. These findings provide a preclinical rationale for continued evaluation of ziftomenib across genetically defined acute leukemias.
  
  

Strategic Financing

• Entered into a strategic financing agreement with affiliates of Oberland Capital providing up to $300 million in potential funding, including up to $275 million in debt financing and $25 million in equity investments, subject to applicable conditions. The financing is expected to support continued investment in KOMZIFTI, ziftomenib development, and darlifarnib monotherapy registrational and combination studies.
  
  
• Received $55 million at closing, comprised of $50 million in debt funding, before fees, and a $5 million equity investment. Additional funding is available through company-option and milestone-based tranches, and an additional tranche of funding is available upon mutual agreement.
  
  
• The debt financing agreement has a seven-year term. Each term loan advanced under the agreement will bear interest at a rate between 6.95% and 8.95%, with 50% of interest capitalized during the first three years following the applicable advance date. The financing also provides for a single-digit royalty tied to U.S. KOMZIFTI net sales, capped at 20% of the aggregate principal amount of term loans advanced under the agreement.

IMPORTANT SAFETY INFORMATION FOR KOMZIFTI FROM THE U.S. PRESCRIBING INFORMATION

Boxed WARNING: DIFFERENTIATION SYNDROME

Differentiation syndrome, which can be fatal, has occurred with KOMZIFTI. Signs and symptoms may include fever, joint pain, hypotension, hypoxia, dyspnea, rapid weight gain or peripheral edema, pleural or pericardial effusions, pulmonary infiltrates, acute kidney injury, and rashes. If differentiation syndrome is suspected, interrupt KOMZIFTI, and initiate oral or intravenous corticosteroids with hemodynamic and laboratory monitoring until symptom resolution; resume KOMZIFTI upon symptom improvement.

WARNINGS AND PRECAUTIONS

Differentiation Syndrome

KOMZIFTI can cause fatal or life-threatening differentiation syndrome (DS). DS is associated with rapid proliferation and differentiation of myeloid cells. Symptoms of DS, including those seen in patients treated with KOMZIFTI, may include fever, hypoxia, joint pain, hypotension, dyspnea, rapid weight gain or peripheral edema, pleural or pericardial effusions, acute kidney injury, and rashes.

In the clinical trial, DS occurred in 29 (26%) of 112 patients with R/R AML with an NPM1 mutation who were treated with KOMZIFTI at the recommended dosage. DS was Grade 3 in 13% and fatal in two patients. In broader evaluation of all patients with any genetic form of AML treated with KOMZIFTI monotherapy in clinical trials, DS occurred in 25% of patients. Four fatal cases of DS occurred out of 39 patients with KMT2A-rearranged AML treated with KOMZIFTI. KOMZIFTI is not approved for use in patients with KMT2A-rearranged AML.

In the 112 patients with an NPM1 mutation, DS was observed with and without concomitant hyperleukocytosis, in as early as 3 days and up to 46 days after KOMZIFTI initiation. The median time to onset was 15 days. Two patients experienced more than one DS event. Treatment was interrupted and resumed in 15 (13%) patients, while it was permanently discontinued in 2 (2%) patients.

Prior to starting treatment with KOMZIFTI, reduce the WBC counts to less than 25 x 10⁹/L. If DS is suspected, interrupt KOMZIFTI, initiate oral or intravenous corticosteroids (e.g., dexamethasone 10 mg every 12 hours) for a minimum of 3 days with hemodynamic and laboratory monitoring. Resume treatment with KOMZIFTI at the same dose level when signs and symptoms improve and are Grade 2 or lower. Taper corticosteroids over a minimum of 3 days after adequate control or resolution of symptoms. Symptoms of DS may recur with premature discontinuation of corticosteroid treatment.

QTc Interval Prolongation

KOMZIFTI can cause QTc interval prolongation. In the clinical trial, QTc interval prolongation was reported as an adverse reaction in 12% of 112 patients treated with KOMZIFTI at the recommended dosage for R/R AML with an NPM1 mutation. QTc interval prolongation was Grade 3 in 8% of patients. The heart-rate corrected QT interval (using Fridericia’s method) (QTcF) was greater than 500 msec in 9% of patients, and the increase from baseline QTcF was greater than 60 msec in 12% of patients. KOMZIFTI dose reduction was required for 1% of patients due to QTc interval prolongation. QTc prolongation occurred in 14% of the 42 patients less than 65 years of age and in 10% of the 70 patients 65 years of age or older.

Correct electrolyte abnormalities, including hypokalemia and hypomagnesemia, prior to treatment with KOMZIFTI. Perform an ECG prior to initiation of treatment with KOMZIFTI, and do not initiate KOMZIFTI in patients with QTcF > 480 msec. Perform an ECG at least once weekly for the first four weeks on treatment, and at least monthly thereafter. Interrupt KOMZIFTI if the QTc interval is > 500 ms or the change from baseline is > 60 ms (Grade 3). In patients with congenital long QTc syndrome, congestive heart failure, electrolyte abnormalities, or those who are taking medications known to prolong the QTc interval, more frequent ECG monitoring may be necessary. Concomitant use of KOMZIFTI with drugs known to prolong the QTc interval may increase the risk of QTc interval prolongation, result in a greater increase in the QTc interval and adverse reactions associated with QTc interval prolongation, including Torsades de Pointes, other serious arrhythmias, and sudden death.

Embryo-Fetal Toxicity

Based on findings in animals and its mechanism of action, KOMZIFTI can cause embryo-fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to the fetus. Advise females of reproductive potential to use effective contraception during treatment with KOMZIFTI and for 6 months after the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with KOMZIFTI and for 3 months after the last dose.

ADVERSE REACTIONS

Fatal adverse reactions occurred in 4 (4%) patients who received KOMZIFTI, including 2 with differentiation syndrome, 1 with infection, and 1 with sudden death. Serious adverse reactions were reported in 79% of patients who received KOMZIFTI. Serious adverse reactions occurring in ≥ 5% of patients included infection without an identified pathogen (29%), febrile neutropenia (18%), bacterial infection (16%), differentiation syndrome (16%), and dyspnea (6%).

Dosage interruption of KOMZIFTI due to an adverse reaction occurred in 54% of patients. Adverse reactions that required dose interruption in ≥ 2% of patients included infection without an identified pathogen (15%), differentiation syndrome (13%), febrile neutropenia (5%), pyrexia (4%), electrocardiogram QT prolonged (4%), leukocytosis (4%), bacterial infection (3%), cardiac failure (2%), cholecystitis (2%), diarrhea (2%), pruritus (2%), and thrombosis (2%). Dose reduction of KOMZIFTI due to an adverse reaction occurred in 4% of patients. Permanent discontinuation of KOMZIFTI due to an adverse reaction occurred in 21% of patients. Adverse reactions that required permanent discontinuation of KOMZIFTI in ≥ 2% of patients were infection without an identified pathogen (8%), bacterial infection (4%), cardiac arrest (2%), and differentiation syndrome (2%).

Most common (≥ 20%) adverse reactions, including laboratory abnormalities, were aspartate aminotransferase increased (53%), infection without an identified pathogen (52%), potassium decreased (52%), albumin decreased (51%), alanine aminotransferase increased (50%), sodium decreased (49%), creatinine increased (45%), alkaline phosphatase increased (41%), hemorrhage (38%), diarrhea (36%), nausea (35%), fatigue (34%), edema (30%), bacterial infection (28%), musculoskeletal pain (28%), bilirubin increased (27%), potassium increased (26%), differentiation syndrome (26%), pruritus (23%), febrile neutropenia (22%), and transaminases increased (21%).

DRUG INTERACTIONS

Drug interactions may occur when KOMZIFTI is concomitantly used with:

• Strong or Moderate CYP3A4 Inhibitors: Monitor patients more frequently for KOMZIFTI-associated adverse reactions.
• Strong or Moderate CYP3A4 Inducers: Avoid concomitant use of KOMZIFTI.
• Gastric Acid Reducing Agents: Avoid concomitant use of KOMZIFTI with proton pump inhibitors (PPIs), H2 receptor antagonists (H2RAs), or locally acting antacids. If concomitant use with H2RAs or locally acting antacids cannot be avoided, modify KOMZIFTI administration time.
  • Take KOMZIFTI 2 hours before or 10 hours after administration of an H2 receptor antagonist.
  • Take KOMZIFTI 2 hours before or 2 hours after administration of a locally acting antacid.
• Drugs that Prolong the QTc Interval: Avoid concomitant use of KOMZIFTI. If concomitant use cannot be avoided, obtain ECGs when initiating, during concomitant use, and as clinically indicated. Interrupt KOMZIFTI if the QTc interval is > 500 ms or the change from baseline is > 60 ms.

USE IN SPECIFIC POPULATIONS

Pregnancy: Based on findings in animals and its mechanism of action, KOMZIFTI can cause embryo-fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Verify pregnancy status in females of reproductive potential prior to starting KOMZIFTI.

Lactation: Because of the potential for adverse reactions in the breastfed child, advise women not to breastfeed during treatment with KOMZIFTI and for 2 weeks after the last dose.

Infertility: Based on findings in animals, KOMZIFTI may impair fertility in females and males of reproductive potential.
