On December 17, 2024 Marker Therapeutics, Inc. (Nasdaq: MRKR), a clinical-stage immuno-oncology company focusing on developing next-generation T cell-based immunotherapies for the treatment of hematological malignancies and solid tumor indications, reported that the Company has been awarded a $9.5 million grant from the Cancer Prevention & Research Institute of Texas (CPRIT) to support the clinical investigation of MT-601 in patients with metastatic pancreatic cancer (Press release, Marker Therapeutics, DEC 17, 2024, View Source [SID1234649159]).

The CPRIT grant is intended to support the Company’s Phase 1 PANACEA study (clinicaltrials.gov Identifier: NCT06549751) evaluating the safety and tolerability of MT-601, a multi-tumor associated antigen (multiTAA)-specific T cell product, in patients with metastatic pancreatic cancer.
The Company’s lead asset, MT-601, is currently being studied in patients with CD19-CAR relapsed lymphoma as the primary indication (clinicaltrials.gov identifier: NCT05798897). Marker previously reported that one of the Principal Investigators presented preliminary safety and efficacy with sustained objective responses observed in three study participants treated at City of Hope National Medical Center (Press Release, April 8, 2024). MT-601 recognizes multiple targets within six tumor-specific antigens that are highly expressed among different cancer indications. Due to the broad target recognition profile of MT-601, the Company plans to investigate its potential application beyond lymphoma in patients with solid tumors.
The use of MT-601 in solid tumors is supported by preliminary efficacy data of a previous study conducted at Baylor College of Medicine investigating multiTAA-specific T cells in patients with pancreatic cancer who received treatment in conjunction with frontline chemotherapy (Phase 1 Trial in Pancreatic Adenocarcinoma (TACTOPS), June 1, 2020; clinicaltrials.gov identifier: NCT03192462). In this study, the multiTAA-specific T cell product targeted five of the six tumor-antigens used in MT-601. In the 13 patients treated, administration of multiTAA-specific T cells was associated with a favorable safety profile and durable cancer control, including 1 complete response, 3 partial responses and 6 patients with stable disease. Notably, measurable tumor responses were observed in 4 patients, and 9 patients exceeded the median overall survival of historical controls of patients receiving chemotherapy alone.
"We are pleased to receive $9.5 million from CPRIT to explore MT-601 in our Phase 1 study in patients with pancreatic cancer," said Juan Vera, M.D., President and CEO of Marker Therapeutics. "The CPRIT application underwent multiple rounds of review by expert panels, and being awarded this grant underscores the innovation behind our therapy and recognizes the potential impact of our study."
Including this CPRIT grant, the Company has been awarded over $30 million in non-dilutive funding from governmental institutions including FDA, NIH and CPRIT. Most recently, the Company was awarded a $2 million grant from the NIH Small Business Innovation Research (SBIR) program to support the investigation of MT-601 in patients with pancreatic cancer. Together with the $9.5 million from CPRIT, Marker will use these funds to advance MT-601 in pancreatic cancer and anticipates clinical program initiation in 2025.
Dr. Vera added: "Being awarded with a total of $9.5 million from CPRIT and $2 million from the NIH SBIR program to advance our lead asset, MT-601, beyond lymphoma to pancreatic cancer is an important acknowledgement of our work and reflects the reviewers’ confidence in our study. With the support of these highly competitive grants from CPRIT and NIH, we will be able to advance MT-601 in pancreatic cancer without affecting operations in the ongoing study of MT-601 in patients with lymphoma."
