Unum Therapeutics to Present Pre-Clinical Data on its Antibody-Coupled T Cell Receptor (ACTR) Platform at the American Society of Hematology (ASH) Summit on Emerging Immunotherapies for Hematological Diseases

July 12, 2018 at 7:00 AM EDT

CAMBRIDGE, Mass., July 12, 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 the Company will be presenting pre-clinical data on the use of ACTR T cells in combination with daratumumab, a CD38-specific antibody, at the American Society of Hematology (ASH) Summit on Emerging Immunotherapies for Hematological Diseases. The summit will take place in Washington DC, later today. 

CD38 is an antigen known to be expressed on tumor cells of multiple myeloma, lymphoma, and AML patients.  Unum has demonstrated in pre-clinical studies that the combination of ACTR T cells with daratumumab can drive potent activity against these tumor cells.  The Company is particularly interested in the potential benefit that ACTR in combination with daratumumab can provide in patients with AML. 

“We believe that using a CD38-specific antibody to direct ACTR attack has the potential to provide meaningful therapeutic benefit to CD38 expressing malignancies, including AML patients for whom treatment options continue to be very limited,” said Seth Ettenberg, Unum’s Chief Scientific Officer. “We look forward to bringing this novel approach into clinical testing in the future.”

CD38 is a difficult antigen to target using conventional T cell therapies, like CAR-T, because it is expressed on T cells. Expression on T cells drives “fratricide” during manufacturing, a process where activated T cells begin to attack and kill themselves. Since ACTR T cells require a targeting antibody to be activated and the targeting antibody is not present during manufacturing, ACTR T cells can be manufactured without triggering self-attack. As a result, ACTR has the potential to pursue T cell targets like CD38.

About Unum Therapeutics
Unum Therapeutics is a clinical-stage biopharmaceutical company focused on the development and commercialization of novel immunotherapy products designed to harness the power of a patient’s immune system to cure cancer. Unum’s novel proprietary technology, Antibody-Coupled T cell Receptor (ACTR), is a universal, engineered cell therapy intended to be used in combination with a wide range of tumor-specific antibodies to target different tumor types. ACTR087 used in combination with rituximab, an anti-CD20 antibody, is Unum’s most advanced product candidate, currently in Phase I clinical testing in adult patients with relapsed or refractory non-Hodgkin lymphoma (r/r NHL). The Company has two additional product candidates in Phase I clinical testing: ACTR087 used in combination with the novel antibody SEA-BCMA in adult patients with relapsed or refractory multiple myeloma and ACTR707, a modified ACTR construct, used in combination with rituximab in adult patients with r/r NHL. In addition, Unum expects to file an investigational new drug application (IND) in 2018 for ACTR707 used in combination with trastuzumab, an anti-human epidermal growth factor receptor 2 (HER2) antibody, to treat patients with HER2+ cancers.

The Company is headquartered in Cambridge, MA.
