CAMBRIDGE, Mass., Jan. 04, 2019 (GLOBE NEWSWIRE) -- Unum Therapeutics Inc. (NASDAQ:  UMRX), a clinical-stage biopharmaceutical company focused on the development of novel cellular immunotherapies, today announced its anticipated milestones for 2019. 

“Unum made substantial progress in 2018 as we reported early data from our programs in non-Hodgkin lymphoma and multiple myeloma, while simultaneously expanding applications of our ACTR platform into solid tumors and introducing a second novel technology platform, BOXR, designed to improve the functionality of engineered T cells,” said Chuck Wilson, CEO of Unum. “We expect 2019 also to be a year of significant momentum, with data expected from all four of our ongoing clinical programs, including readouts from the ATTCK-20-03 and ATTCK-17-01 trials, as well as an initial data readout from our first study in solid tumors. Additionally, we continue to innovate in the field of cell therapy and have recently nominated our first development candidate from our BOXR technology platform to advance toward clinical development.”

Anticipated 2019 Milestones

ACTR707 + rituximab in r/r NHL

• Complete the dose escalation phase of ATTCK-20-03, the ongoing, multicenter Phase 1 study testing ACTR707 in combination with rituximab to treat patients with relapsed/refractory B cell non-Hodgkin lymphoma. Advance into cohort expansion to confirm the preliminary recommended Phase 2 dose.
• Report results from the dose escalation phase and preliminary data from the cohort expansion phase of the ATTCK-20-03 study.

ACTR087 + SEA-BCMA in r/r multiple myeloma

• Progress dose escalation of ACTR087 and SEA-BCMA in ATTCK-17-01, a Phase 1, multi-center, open-label trial designed to test the safety, tolerability and anti-myeloma activity of the combination in patients with r/r multiple myeloma.
• Report clinical data from multiple cohorts of the dose escalation phase.

ACTR707 + trastuzumab in HER2+ advanced cancers

• Enroll and dose patients in Unum’s first ACTR T cell study in solid tumors, ATTCK-34-01, a multicenter, single-arm, open-label dose escalation study evaluating ACTR T cells in combination with trastuzumab in patients with HER2+ advanced cancers.
• Report initial clinical data from ongoing dose escalation.

ACTR087 + rituximab in r/r NHL

• Complete enrollment in ATTCK-20-2, a Phase I clinical trial evaluating safety and anti-lymphoma activity of ACTR087 in combination with rituximab in patients with relapsed or refractory B cell NHL, and report data from the trial.

BOXR Platform

• Continued progress with new Bolt-On Chimeric Receptor technology platform (“BOXR”) that improves T cell functionality by countering immunosuppression in solid tumor cancers. Initiate preclinical development of BOXR1030, which has been nominated as the first product candidate from this platform.
