Tevimbra
Pronunciation: TEV-im-bra
Generic name: tislelizumab-jsgr
Dosage form: injection for intravenous infusion
What is Tevimbra?
Tevimbra (tislelizumab-jsgr) is a programmed death receptor-1 (PD-1) blocking antibody that is given intravenously (into a vein) and may be used to treat adults with esophageal squamous cell carcinoma that has spread to other parts of the body (metastatic) or cannot be surgically removed.
- Tevimbra is given after prior treatments that did not include a PD-L 1 inhibitor.
Tevimbra (tislelizumab-jsgr) belongs to the class of medicines known as checkpoint inhibitors and works by blocking the PD-1 pathway to help prevent cancer cells from hiding from the immune system, boosting the immune system's response against cancer. Tevimbra is highly specific for PD-1.
Tevimbra was FDA-approved on 13 March 2024.
