New T-Cell Immunotherapy Stops Mesothelioma Growth and Spread
A small Phase 1 study of a new type of T-cell immunotherapy has delivered remarkable results for four mesothelioma patients, leading its creators to move forward to Phase 2 testing. The new technology, called TC-210, uses TRuC-T cells instead of CAR-T or other types of immunotherapy.
TCR² Therapeutics Reports Tumor Regression in Mesothelioma Patients
According to researchers from TCR² Therapeutics, their initial patient study of TC-210 yielded tumor regression in all five cancer patients receiving TC-210, four of whom have malignant mesothelioma. The drug fights cancer by restarting the body’s natural killer T-cell response after mesothelin, an antigen linked to mesothelioma tumor spread and growth, has shut it down.
The scientists explain their process as a combination of mesothelioma patients’ blood and TC-210, extracting patient T-cells and combining them with the immunotherapy. The result is a drug that responds to the mesothelin on the surface of patients’ cancer cells in a way that both works better than other immunotherapy approaches and leads to fewer complications.
Phase I Trial Included Four Previously-Treated Mesothelioma Patients
One of the most encouraging aspects of the Phase I clinical trial is the fact that the four mesothelioma patients and one ovarian cancer patient who participated had all been previously – and unsuccessfully – treated for their cancers. The positive response that all five experienced gives significant hope to patients whose cancers had previously seemed intractable.
With the Phase I trial successfully showing either decreases in tumor size or six-month stabilization of tumors with good levels of safety, the scientists from TCR² Therapeutics are ready to move on to Phase II so that they can determine the optimal dose. Speaking of their results, Garry Menzel, PhD, President and CEO of TCR² Therapeutics said, “We are delighted that our very first dose of TC-210 induced consistent tumor regression and clinical benefit in heavily pre-treated cancer patients. There are very few options for patients with solid tumors and those expressing mesothelin represent a significant frontier of unmet medical need.”
