Abstract:Purpose: To overcome the limited efficacy of immune checkpoint blockade, there is a need to find novel cancer immunotherapeutic strategies for the optimal treatment of cancer. The novel anti-4-1BB×PD-L1 bispecific antibody—ABL503 (also known as TJ-L14B)—was designed to simultaneously target PD-L1 and 4-1BB, and demonstrated strong antitumor T-cell responses without considerable toxicity. Here, we investigated how the combination of ABL503 and anti-PD-1 blockade affected the reinvigoration of exhausted tumor-in… Show more
