A study published in the journal Nature reports results of the first-in-human phase I clinical trials of a novel immunotherapy approach for solid tumors expressing glypican-3. Researchers at Baylor College of Medicine and Texas Children’s Cancer Center led the study, which tested chimeric antigen receptor T cells enhanced with the protein interleukin-15.
Rezatapopt monotherapy generated a 33% overall response rate in 97 patients with solid tumors spanning across eight different cancers (ovarian, lung, breast, endometrial, head and neck, colorectal, gallbladder, and ampullary carcinoma) and a median duration of response of 6.2 months, according to PYNNACLE phase II clinical trial interim data. These were patients whose tumors were TP53 Y220C mutated and KRAS wild-type.
