Marker Therapeutics Receives FDA Orphan Drug Designation for its Multi-Antigen Targeted T Cell Therapy for Acute Myeloid Leukemia – BioSpace

HOUSTON, April 29, 2020 /PRNewswire/ -- Marker Therapeutics, Inc.(Nasdaq:MRKR), a clinical-stage immuno-oncology company specializing in the development of next-generation T cell-based immunotherapies for the treatment of hematological malignancies and solid tumor indications, today announced that theUnited States Food and Drug Administration(FDA) Office of Orphan Products Development has granted Orphan Drug designation to MT-401, a multi-tumor-associated antigen (MultiTAA)-specific T cell product for the treatment of patients with acute myeloid leukemia (AML), following allogeneic stem cell transplant.

"We are pleased that theFDAhas granted orphan designation to MT-401, our novel MultiTAA-specific T cell product candidate and believe it is supportive of its potential to treat post allogeneic stem cell transplant patients with AMLa devastating and pervasive blood disease with a high medical need for a treatment. In investigator-sponsored trials, our MultiTAA-specific T cell product candidate was well-tolerated and we have observed clinical benefit across various liquid and solid tumors, suggesting the product candidate's ability to induce a patient's own T cells to expand for a more durable anti-tumor effect. We look forward to initiating our Company-sponsored Phase 2 study in patients with post allogeneic stem cell transplant AML," said Peter L. Hoang, President & CEO of Marker Therapeutics.

Orphan designation is granted by theFDA Office of Orphan Products Developmentto advance the evaluation and development of safe and effective therapies for the treatment of rare diseases or conditions affecting fewer than 200,000 people in the U.S. Under the Orphan Drug Act, theFDAmay provide grant funding toward clinical trial costs, tax credits,FDAuser-fee benefits, and seven years of market exclusivity inthe United Statesfollowing marketing approval by theFDA. The granting of an orphan designation request does not alter the standard regulatory requirements and process for obtaining marketing approval.

About Marker Therapeutics, Inc.Marker Therapeutics, Inc. is a clinical-stage immuno-oncology company specializing in the development of next-generation T cell-based immunotherapies for the treatment of hematological malignancies and solid tumor indications. Marker's cell therapy technology is based on the selective expansion of non-engineered, tumor-specific T cells that recognize tumor associated antigens (i.e. tumor targets) and kill tumor cells expressing those targets. This population of T cells is designed to attack multiple tumor targets following infusion into patients and to activate the patient's immune system to produce broad spectrum anti-tumor activity. Because Marker does not genetically engineer its T cell therapies, we believe that our product candidates will be easier and less expensive to manufacture, with reduced toxicities, compared to current engineered CAR-T and TCR-based approaches, and may provide patients with meaningful clinical benefit. As a result, Marker believes its portfolio of T cell therapies has a compelling product profile, as compared to current gene-modified CAR-T and TCR-based therapies.
