WALTHAM, Mass., May 9, 2022 /PRNewswire/ -- Syndax Pharmaceuticals, Inc. ("Syndax," the "Company" or "we") (Nasdaq: SNDX), a clinical-stage biopharmaceutical company developing an innovative pipeline of cancer therapies, today reported its financial results for the first quarter ended March 31, 2022. In addition, the Company provided a clinical and business update.

"Throughout the first quarter, we continued to realize significant progress advancing our two pivotal programs, for which we expect to report topline data starting in the first half of 2023," said Michael A. Metzger, Chief Executive Officer. "We firmly believe revumenib (SNDX-5613) is positioned to serve as a first-to-market and best-in-class menin inhibitor for patients with NPM1 and MLLr acute leukemias. We have also begun exploring its activity beyond use as a monotherapy agent through initiation of two new trials, including in combination with venetoclax-azacitidine for use as a frontline treatment, and in combination with chemotherapy for relapsed/refractory (R/R) disease. Beyond acute leukemias, we intend to assess revumenib's (SNDX-5613) potential in additional areas where menin inhibition could have a strong therapeutic benefit, and we look forward to commencing a proof-of-concept clinical trial in patients with advanced colorectal cancer (CRC), a highly underserved area lacking effective therapeutic options, in the fourth quarter of the year."

"Additionally, enrollment continues in the ongoing global pivotal Phase 2 AGAVE-201 trial of axatilimab in chronic graft-versus-host disease (cGVHD), with topline data expected in the first half of 2023 and a potential Biologic License Application (BLA) filing in 2023. Supported by recent receipt of Fast Track Designation (FTD) by the U.S. Food and Drug Administration (FDA), we believe axatilimab has the potential to play a meaningful role in the cGVHD treatment landscape. Furthermore, as previously announced, we are committed to unlocking axatilimab's full potential in additional fibrotic diseases where the monocyte-macrophage lineage plays a vital role, and remain on track to commence a Phase 2 trial in idiopathic pulmonary fibrosis (IPF) in the fourth quarter of this year."

Recent Pipeline Progress and Anticipated Milestones

Revumenib (SNDX-5613)

  • The pivotal Phase 2 portion of AUGMENT-101 is ongoing and the Company continues to expect completion of enrollment in at least one of the three pivotal cohorts later this year. The trials are expected to enroll a total of 64 adult and up to 10 pediatric patients across each of three distinct trial populations: patients with NPM1 mutant acute myeloid leukemia (AML), patients with MLLr AML, and patients with MLLr acute lymphocytic leukemia (ALL). Based on discussions with the U.S. FDA, AUGMENT-101 may serve as the basis for regulatory filings in each of the three distinct populations. The Company expects to receive initial topline data from the trials starting in the first half of 2023, with the potential for the first New Drug Application filing in 2023.
  • Two additional trials, BEAT-AML and AUGMENT-102, are now underway to assess the safety, tolerability, and preliminary anti-leukemic efficacy of revumenib (SNDX-5613) and establish an appropriate Phase 2 dose. BEAT-AML is a front-line combination trial of revumenib (SNDX-5613) with venetoclax and azacitidine being conducted as part of the Leukemia & Lymphoma Society's Beat® AML Master Clinical Trial. The primary endpoint of the Phase 1 portion of the BEAT-AML trial is to determine the recommended Phase 2 dose of the combination. The Company also initiated a trial in combination with chemotherapy in patients with R/R NPM1 or MLLr acute leukemias, known as AUGMENT-102. The primary endpoint of AUGMENT-102 will assess the safety, tolerability, and recommended Phase 2 dose criteria. Topline data from the trials are expected beginning in 2023.
  • The Company today announced it intends to initiate a proof-of-concept clinical trial to evaluate revumenib (SNDX-5613) in patients with unresectable metastatic microsatellite stable CRC, which represents the second leading cause of cancer death in the U.S. with an estimated incidence of over 55,000 patients per year1,2. Activation of the Wnt/b-catenin signaling pathway is believed to be a key initiating step and growth driver for the majority of CRC tumors. The menin-MLL1 protein complex has recently been shown to regulate b-catenin activity and in preclinical models, disrupting this complex through menin inhibition blocks growth of Wnt/b-catenin driven CRC tumors. The Company is expected to commence the trial in the fourth quarter of 2022.


  • The Company today announced that the U.S. FDA has granted FTD to axatilimab for the treatment of patients with cGVHD after failure of two or more lines of systemic therapy. FTD is designed to facilitate the development and expedite the review of drugs to treat serious conditions and fulfill an unmet medical need, enabling drugs to reach patients earlier.
  • Enrollment is ongoing in the Company's global pivotal Phase 2 AGAVE-201 trial of axatilimab in patients with cGVHD. The trial is evaluating the safety and efficacy of three doses and schedules of axatilimab. The primary endpoint will assess objective response rate based on the 2014 NIH consensus criteria for cGVHD, with key secondary endpoints including duration of response and improvement in modified Lee Symptom Scale score. The Company remains on track to report topline data in the first half of 2023, with the potential for a BLA filing in 2023.
