FAP-Targeted 4-1BB Agonist Tamps Down Advanced Tumors

Findings from a phase I study of the bispecific antibody RO7122290, which targets CD137 and the fibroblast activity protein, show that it produces responses in patients with advanced solid tumors-without the liver toxicity associated with earlier therapies targeting CD137. Additional research evaluating RO7122290 in combination with atezolizumab or other immune agents is planned.
