Briggs Morrison, MD Chief Executive Officer of @Syndax discusses a preclinical study on the activity of menin-MLL inhibition for the treatment of NPM1 in AML.

___________

Syndax Pharmaceuticals, Inc. ("Syndax," the "Company" or "we") (Nasdaq: SNDX), a clinical stage biopharmaceutical company developing an innovative pipeline of cancer therapies, today announced that Science magazine has published a preclinical report supporting the potential role of MLL1-Menin inhibition in the management of nucleophosmin (NPM1) mutant acute myeloid leukemia (AML). The article, "Therapeutic targeting of preleukemia cells in a mouse model of NPM1 mutant acute myeloid leukemia," will be published in the journal's January 31, 2020 issue and is currently available online.

This study examined the activity of VTP-50469, an orally-available inhibitor of MLL1-Menin interaction and close analog of the Company's lead Menin inhibitor, SNDX-5613, for the treatment of established NPM1 AML and the possible prevention of the disease in high-risk populations. Using preclinical models of NPM1 AML, the authors established that the presence of an NPM1 mutation is a clear indicator of pre-leukemic activity and represents a critical step in the development of AML. VTP-50469 was shown to eradicate NPM1 mutant cells at various stages of disease development, suggesting that Menin-MLL inhibition could potentially serve either as a targeted preventive therapy or as a treatment of established disease.

"These unprecedented findings highlight the potential for single agent Menin-MLL inhibition to rapidly eradicate fully developed NPM1 mutant leukemia, even in the case of aggressive relapsed AML," said Scott A. Armstrong, M.D., Ph.D., President, Dana-Farber/Boston Children's Cancer and Blood Disorders Center, and Chairman, Department of Pediatric Oncology, Dana-Farber Cancer Institute, and senior author of the study. "In addition, these results provide support for a Menin-MLL inhibitor to serve as a novel strategy to prevent AML development in high-risk patient populations, as NPM1 mutations are acquired in pre-leukemic clones."

"NPM1 mutant AML represents the most common type of cytogenetically normal AML," said Briggs W. Morrison, M.D., Chief Executive Officer of Syndax. "On the heels of our recent Cancer Cell publication, these findings add to the growing body of compelling preclinical data supporting the potential for SNDX-5613 to serve as an effective intervention for both NPM1 mutant AML and MLL-r acute leukemias. We are committed to providing patients with more targeted therapeutic options and are hopeful that these findings will translate into the clinic in our ongoing Phase 1/2 AUGMENT-101 trial."
