Ziftomenib has received Breakthrough Therapy, Fast Track, and Orphan Drug Designations. The FDA has a 60-day filing review period to determine whether the NDA is complete and accepted for review; Kura expects to receive notification from the FDA on this preliminary evaluation in the second quarter of 2025. Priority Review was requested, which, if granted, would provide a target FDA review period of six months after NDA acceptance.
"This NDA submission brings us one step closer to our goal of advancing ziftomenib to market as a new therapeutic option for adult patients with R/R NPM1-m AML, a devastating disease for which there are currently no FDA-approved targeted therapy options," said Troy Wilson, Ph.D., J.D., President and Chief Executive Officer of Kura Oncology. "We look forward to working closely with the FDA throughout the review process and are optimistic about the potential of ziftomenib to impact patients with NPM1-mutant AML. We extend our gratitude to the team at Kura, our dedicated investigators, study site teams, and most importantly, to the patients who participated in our clinical trials, and their families and caregivers, who all helped make this possible. We appreciate the support and cooperation we enjoy with our partner Kyowa Kirin, and we look forward with confidence to the continued progress of this program and our collaboration."
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 such 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 potent and selective, oral, investigational menin inhibitor currently in development for the treatment of genetically defined AML patients with high unmet need. In April 2024, ziftomenib received Breakthrough Therapy Designation (BTD) from the FDA for the treatment of adult patients with R/R AML with a NPM1 mutation based on data from Kura’s KOMET-001 clinical trial.
