CAMBRIDGE, Mass., Aug. 13, 2018 (GLOBE NEWSWIRE) -- Unum Therapeutics Inc. (NASDAQ: UMRX), a clinical-stage biopharmaceutical company focused on the development of cellular immunotherapies based on its novel, universal Antibody-Coupled T Cell Receptor (ACTR) technology platform, today announced that an investigational new drug (IND) application is now active for ACTR T cells in combination with trastuzumab for the treatment of patients with HER2+ advanced cancers. This represents the first solid tumor product candidate based on Unum’s novel, universal ACTR technology, and the fourth clinical trial program for the Company.

“We are very happy to reach this important milestone for patients and for Unum,” said Chuck Wilson, Chief Executive Officer of Unum. “ACTR represents a promising novel technology that can be used to target different tumor types and it’s exciting to expand its application to target solid tumors.  We are committed to developing ACTR for patients with HER2+ advanced cancers who need better treatment options.”

Under this IND, Unum is preparing to initiate a multi-center Phase I trial, called ATTCK-34-01, by the end of 2018 in patients with HER2+ advanced cancers. ATTCK-34-01 is designed as a dose escalation study where both the ACTR T cell drug product and trastuzumab doses are escalated in order to define the safety, tolerability, and anti-tumor activity of the combination. Expansion at the recommended Phase 2 dose is planned.
