Kura Oncology Announces Publication of Ziftomenib Phase 1 Results in The Lancet Oncology
“The results from the KOMET-001 Phase 1 study are encouraging as they demonstrate meaningful benefit of ziftomenib in NPM1-mutant acute myeloid leukemia (AML), and publication of these data expands the growing evidence supporting the efficacy and safety of ziftomenib in a disease indication of unmet need,” said
The KOMET-001 study is a Phase 1/2 global, open-label, multi-cohort clinical trial evaluating the safety, tolerability and clinical activity of ziftomenib in relapsed/refractory (R/R) AML. In the Phase 1a dose escalation portion, patients received ziftomenib once daily in 28-day cycles and in the Phase 1b dose validation/expansion portion, patients were randomized to two parallel cohorts at 200 mg and 600 mg. As of the data cutoff on
“Our Phase 1 study provided the critical safety and clinical activity data in order to determine the RP2D and support our pivotal Phase 2 registration-directed trial in patients with NPM1-mutant AML,” said

About NPM1-mutant AML
AML is the most common acute leukemia in adults and begins when the bone marrow makes abnormal myeloblasts (white blood cells), red blood cells or platelets. Despite the many available treatments for AML, prognosis for patients remains poor and a high unmet need remains. The menin pathway is considered a driver for multiple genetic alterations of the disease, of which NPM1 mutations are among the most common, representing approximately 30% of AML cases. While patients with NPM1-m AML have high response rates to frontline therapy, relapse rates are high and survival outcomes are poor, with only 30% overall survival at 12 months in the R/R setting. Additionally, NPM1 mutations frequently occur with co-mutations in other disease-associated genes, including FLT3, DNMT3A and IDH1/2, with prognosis heavily influenced by the presence of co-occurring mutations. Adult patients with NPM1-m AML and select co-mutations and/or R/R disease have a poor prognosis, with median overall survival of only approximately 7.8 months in 2nd line, 5.3 months in 3rd line, and 3.5 months following the 4th line1. There are currently no FDA-approved therapies targeting NPM1-m AML.
About Ziftomenib
Ziftomenib is a novel, once-daily, oral investigational drug candidate targeting the menin-KMT2A/MLL protein-protein interaction for treatment of genetically defined AML patients with high unmet need. In the KOMET-001 Phase 1 study, ziftomenib demonstrated encouraging safety and tolerability with reported events consistent with features and manifestations of underlying disease. Clinical activity of ziftomenib as a monotherapy was optimal at the 600 mg daily dose and a 35% complete remission rate was observed in 20 patients with NPM1-mutant AML treated at the recommended Phase 2 dose (600 mg). Ziftomenib has received Breakthrough Therapy Designation (BTD) from the
About
Kura Oncology is a clinical-stage biopharmaceutical company committed to realizing the promise of precision medicines for the treatment of cancer. The Company’s pipeline consists of small molecule drug candidates that target cancer signaling pathways. Ziftomenib, a once-daily, oral drug candidate targeting the menin-KMT2A protein-protein interaction, has received BTD for the treatment of R/R NPM1-mutant AML. Kura has completed enrollment in a Phase 2 registration-directed trial of ziftomenib in R/R NPM1-mutant AML (KOMET-001). The Company is also conducting a series of clinical trials to evaluate ziftomenib in combination with current standards of care in newly diagnosed and R/R NPM1-mutant and KMT2A-rearranged AML. Kura is evaluating KO-2806, a next-generation farnesyl transferase inhibitor (FTI), in a Phase 1 dose-escalation trial as a monotherapy and in combination with targeted therapies (FIT-001). Tipifarnib, a potent and selective FTI, is currently in a Phase 1/2 trial in combination with alpelisib for patients with PIK3CA-dependent head and neck squamous cell carcinoma (KURRENT-HN).
