ECOG-ACRIN Provides Syndax Pharmaceuticals With Results of Phase 3 E2112 Trial of Entinostat Plus Exemestane in Patients with HR+, HER2- Breast Cancer

On May 21, 2020 Syndax Pharmaceuticals, Inc. (Nasdaq: SNDX) reported receipt of the final results of E2112, the Phase 3 clinical trial conducted by ECOG-ACRIN Cancer Research Group (ECOG-ACRIN) and sponsored by the National Cancer Institute (NCI), that evaluated the investigational compound entinostat, Syndax’s class I HDAC inhibitor, plus exemestane in patients with advanced hormone receptor positive, human epidermal growth factor receptor 2 negative (HR+, HER2-) breast cancer who have progressed on a non-steroidal aromatase inhibitor (Press release, Syndax, MAY 21, 2020, View Source [SID1234558393]). The trial did not achieve the primary endpoint of demonstrating a statistically significant overall survival (OS) benefit over hormone therapy alone.

"We’re disappointed that the combination of entinostat and exemestane did not demonstrate a survival benefit in this historically difficult-to-treat patient population," said Briggs W. Morrison, M.D., Chief Executive Officer of Syndax. "On behalf of the entire Syndax team, we extend our sincerest gratitude to all the patients, their families and the investigators who participated in this important trial, as well as our colleagues at ECOG-ACRIN and the NCI. Based on these results, we will not be filing a New Drug Application with the U.S. Food and Drug Administration for metastatic breast cancer."

Dr. Morrison added, "We remain focused on advancing our broader portfolio, including our targeted therapy, SNDX-5613, an inhibitor of the Menin-MLL interaction, and axatilimab, our anti-CSF-1R monoclonal antibody. Later this year, we expect to present additional clinical data from the AUGMENT-101 trial of SNDX-5613 in adults with relapsed/refractory acute leukemias. Based on preclinical data reported to date, as well as recent Phase 1 results representing the first clinical evidence that inhibition of the Menin-MLL1 interaction can induce response in patients with genetically-defined acute leukemias, we believe SNDX-5613 has the potential to offer patients with both NPM1 mutant acute myeloid leukemia and MLL-r acute leukemias a much-needed, effective therapeutic option. We also anticipate the presentation of additional results from our ongoing Phase 1/2 trial of axatilimab in patients with chronic graft versus host disease in the fourth quarter of this year."

The E2112 trial was designed and conducted independently by ECOG-ACRIN under the sponsorship of the NCI, which is part of the National Institutes of Health. The double-blind, placebo-controlled trial randomized a total of 608 patients with HR+, HER2- advanced breast cancer to receive exemestane in combination with entinostat or placebo.

A phase I, first-in-human, open-label, dose-escalation study of MGD013, a bispecific DART molecule binding PD-1 and LAG-3, in patients with unresectable or metastatic neoplasms (Abstract #3004)
Preliminary dose escalation results from a phase I/II, first-in-human study of MGC018 (anti-B7-H3 antibody-drug conjugate) in patients with advanced solid tumors (Abstract #3071, Poster #135)
About MGD013

MGD013 is an investigational, first-in-class bispecific, tetravalent DART molecule targeting PD-1 and LAG-3. MGD013 has been engineered to concomitantly or independently bind to PD-1 and LAG-3 and disrupt these non-redundant inhibitory pathways to further restore exhausted T-cell function. MGD013 is being evaluated in a Phase 1 dose expansion study as monotherapy in several tumor types, including both solid tumors and hematological malignancies, and in combination with margetuximab, an investigational Fc-engineered monoclonal antibody targeting HER-2, in a cohort of patients with advanced HER2-positive cancers (NCT03219268). MGD013 will also be evaluated in combination with margetuximab and chemotherapy as part of the ongoing Phase 2/3 MAHOGANY study in patients with HER2-positive gastric or gastroesophageal junction cancer (NCT04082364). MacroGenics’ regional partner in Greater China, Zai Lab, plans to participate in MAHOGANY and is also evaluating MGD013 independently in Phase 1 combination studies with niraparib, a PARP inhibitor, and brivanib, a dual target tyrosine kinase inhibitor of the VEGF and FGF receptors, for the study of advanced gastric cancer and hepatocellular carcinoma, respectively.

About MGC018

MGC018 is an investigational antibody-drug conjugate (ADC) that is designed to target solid tumors expressing B7-H3, a protein in the B7 family of immune regulator proteins. B7-H3 is widely expressed on many different solid tumor types, with limited expression on normal tissues. Over-expression of B7-H3 is associated with disease severity, risk of recurrence, and reduced survival. MGC018 uses a synthetic duocarmycin-based payload with a cleavable peptide linker that was licensed from Byondis (formerly Synthon Biopharmaceuticals). Duocarmycins are potent cell cycle independent DNA-damaging alkylating agents and are not subject to multi-drug resistance. MGC018 is being evaluated in a Phase 1 dose escalation study in patients with advanced solid tumors (NCT03729596).
