Ipilimumab was the first checkpoint inhibitor approved by the FDA for the treatment of metastatic melanoma. This monoclonal antibody inhibits CTLA-4 receptor activity. Moreover, inhibition of PD-1 and other immune checkpoint proteins has revealed additional strategies to enhance immune responses against ...
Both anti-CTLA4/anti-PD-L1 and anti-VEGF/anti-PDL1 are FDA approved immune checkpoint inhibitor regimens. Here we tested the combination of anti-CTLA4 + anti-VEGF + anti-PD-L1 in patients with cholangiocarcinoma (CCA). Methods In this open-label phase II study patients with histologically ...
therapies. Notably, Atezolizumab (also known as MPDL3280A), a fully humanized IgG1 (N298A) mAb that blocks the interaction of PD-L1 with PD-1 and induces anti-tumor immune reactivation, has been approved by the FDA for combinational use in the treatment of lung and breast cancer [2, ...
However, anti-PD-1 mono- clonal antibodies by blocking the interaction of PD-1 with its ligands, PD-L1/PD-L2, reinvigorate the anti-tumor T cell responses and enhancing anti-tumor immunity [6]. In the recent years, the US Food and Drug Administra- tion (FDA) has approved several anti...
The tumor microenvironment plays an important role in good prognosis in immunotherapy based on programmed death-ligand 1/programmed cell death protein 1/cluster of differentiation 80 (PD-L1/PD-1/CD80) immune checkpoint inhibitors [28]. Durvalumab is an FDA-approved anti-PD-L1 monoclonal antibody ...

mPDL1HCv1-E-sLAG3 was a single domain antibody fused to a monoclonal antibody construct comprising a polypeptide chain consisting of an anti-PD-L1 heavy chain fused with an anti-LAG-3 single domain antibody (sdAb, VHH), and a second polypeptide chain consisting of an anti-PD-L1 light ...
with PD-L1 mAb, has shown satisfactory anti-tumor effects in both pre-clinical and clinical trials. At present, PD-1 mAb has been approved by U.S. FDA for the treatment of various tumors, including non-small cell lung cancer, melanoma, head and neck cancer, etc. PD-L1 mAb has also ...
FDA in 2017), esophageal cancer (Kato K et al., Lancet Oncol., 2019; 20(11): 1506-17), mesothelioma (Scherpereel A et al., Lancet Oncol., 2019; 20(2): 239-253) and the like, the PD-1/PDL-1 antibodies show good efficacy, and considering that the PD-1 pathway has a ...
Programmed cell death 1 ligand 1 (PDL1)/programmed cell death 1 (PD1) blockade immunotherapy provides a prospective strategy for the treatment of colorectal cancer (CRC), but various constraints on the effectiveness of the treatment are still remaining. As reported in previous studies, follistatin-...
