Jemperli

Generic name: Dostarlimab-gxly
Dosage form: injection
Drug class: Anti-PD-1 and PD-L1 monoclonal antibodies (immune checkpoint inhibitors)

Usage of Jemperli

Jemperli is a prescription medicine used for the treatment of mismatch repair deficient (dMMR) or microsatellite instability-high (MSI-H) endometrial cancer, and dMMR solid tumors.

Jemperli belongs to the class of drugs called programmed death receptor-1 (PD-1)–blocking antibodies. In healthy T-cells, PD-1 acts as a brake that prevents the cells from creating an out-of-control immune response, but in tumors, PD-1 can make T-cells iNACtive preventing them from killing cancer cells.

Jemperli works in the treatment of dMMR/MSI-H endometrial cancer and dMMR solid tumors by binding to the PD-1 receptor on T-cells to block the interaction with the PD-1 ligands PD-L1 and PD-L2, allowing the T-cells to activate and to attack and kill the cancer cells.

Get emergency medical help if you have signs of an allergic Reaction to Jemperli (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning eyes, skin pain, red or purple skin rash with blistering and peeling).

Jemperli strengthens your immune system to help it attack cancer cells, but it may also attack healthy cells and you could develop serious or fatal side effects. See Important information.
