Dostarlimab Jemperli
A drug approved for colorectal cancer. It appears in 14 clinical trials.
What it is
Dostarlimab is a humanized monoclonal antibody that blocks the PD-1 (programmed death-1) immune checkpoint receptor. It is used specifically in colorectal cancer patients whose tumors exhibit microsatellite instability-high (MSI-H) or deficient mismatch repair (dMMR) characteristics. The drug has shown remarkable efficacy in both neoadjuvant and perioperative settings for locally advanced MSI-H/dMMR colorectal cancers, including stage II and III colon cancers.
How it works
Dostarlimab binds to the PD-1 receptor on T-cells, preventing the interaction between PD-1 and its ligands PD-L1 and PD-L2. This blockade removes the inhibitory signals that normally suppress T-cell activation, allowing the immune system to recognize and attack cancer cells more effectively. The mechanism is particularly effective in MSI-H/dMMR tumors, which typically have high tumor mutational burden and increased neoantigen expression.
