Unum Therapeutics announces Phase 1 clinical updates for T-cell therapies
Unum Therapeutics announced Phase 1 clinical updates for its Antibody-Coupled T cell Receptor engineered T-cell therapies, ACTR707 and ACTR087, in patients with relapsed or refractory CD20+ non-Hodgkin lymphoma. "The clinical data presented at this year's ASH include updates from the ongoing Phase 1 trial of ACTR707 in combination with rituximab and the completed Phase 1 trial of ACTR087 in combination with rituximab, both conducted in patients with relapsed or refractory CD20+ NHL," said Jessica Sachs, M.D., Chief Medical Officer of Unum. "The data with ACTR707 at this year's ASH continue to support further dose-escalation in this Phase 1 trial and provide proof-of-mechanism for the ACTR platform that we are also applying in our lead program, a Phase 1 trial with ACTR707 in combination with trastuzumab in HER2+ solid tumor cancers. Safety data from the Phase 1 trial with ACTR087 presented at this year's ASH provide learnings that are being applied to ongoing clinical trials with ACTR T cell products. A complete response was achieved in 40% of patients in Cohorts 1 through 4. Of the eight complete responders, four remained in complete response at six months of follow-up, two remain in complete response but have not yet reached the six-month timepoint for evaluation, and two progressed before the six-month timepoint.
