The FDA recently approved an anti-CTLA-4 antibody (Iplimumab) for the treatment of metastatic melanoma. This decision was based on Phase III results, which demonstrate that blocking this immune checkpoint provides a survival advantage in patients with advanced disease. As a single agent, ...
an recombinant anti-CTLA-4 fully human monoclonal antibody(mAb) injection, has been approved by the National Medical Products Administration (NMPA), for the treatment of hepatocellular carcinoma(HCC).

2.1CTLA-4 inhibitors Ipilimumab(Yervoy®; Bristol-Myers Squibb) was the firstimmune checkpoint inhibitorto gain Food and Drug Administration (FDA) approval after trials in metastaticmelanomain 2011 [13]. Ipilimumab is a fullyhuman immunoglobulin(Ig)G1monoclonal antibodytargetingCTLA-4[13]. Ipilimumab...
This section compares the effect of CTLA-4 blockade on cancer treatment by the antibody ipilimumab and the H11 nanobody. In cancer therapy, two factors play an essential role in generating an effective Anti-CTLA-4 antibody response; one is increasing the expression of CTLA-4 on tumor-associated...
(PD-L1) have been FDA-approved and widely used. CTLA-4 is a classical immune checkpoint molecule, acting as a CD28 homolog with a stronger binding affinity to its receptor B7-1 (CD80) or B7-2 (CD86). As the first available ICI, the humanized CTLA-4 antibody ipilimumab has ...
Ipilimumab (MDX-010, Yervoy; Bristol-Myers Squibb), a fully human monoclonal antibody against CTL antigen 4 (CTLA-4), was recently approved by the U.S. Food and Drug Administration (FDA) for the treatment of metastatic melanoma. In both early- and late-phase trials, ipilimumab has shown ...
Concerning the combination of PD-L1 inhibitors and CTLA-4 inhibitors, durvalumab plus tremelimumab represents one of the most notable therapeutic regimens. Durvalumab functions as a PD-L1 monoclonal antibody that blocks the interaction between PD-L1 and PD-1 with high affinity and selectivity [85],...
