Jemperli (Dostarlimab, anti-PD-1) (Dostarlimab) — Uses, Dosage, Side Effects & Safety

Drug class: Anti-PD-1 Monoclonal Antibody (Immune Checkpoint Inhibitor)

Overview

Jemperli (dostarlimab) is a prescription medicine used to treat certain types of endometrial cancer and other solid tumors that have a specific genetic feature called mismatch repair deficiency (dMMR) or microsatellite instability-high (MSI-H). It is typically used when the cancer has progressed during or after previous treatments, or when other treatments are not suitable. Jemperli works by helping your immune system recognize and attack cancer cells. It blocks a protein called PD-1 on immune cells, which can allow your body’s natural defenses to better target and destroy cancer. Key points for patients: Jemperli is given as an intravenous infusion by a healthcare professional, usually every 3 or 6 weeks. It can cause immune-related side effects, so regular monitoring is important. Tell your doctor about any new symptoms, especially fever, cough, diarrhea, or skin changes.
