| Therapy Description |
Loqtorz (toripalimab-tpzi) is a monoclonal antibody that targets PD-1 (PDCD1) and inhibits binding of the PD-L1 (CD274) ligand, potentially resulting in enhanced anti-tumor immune response and decreased tumor growth (PMID: 28317872; PMID: 32277740, PMID: 32406293, PMID: 32321714). Loqtorz (toripalimab-tpzi) in combination with cisplatin and gemcitabine is FDA-approved for use in adult patients with metastatic or recurrent, locally advanced nasopharyngeal carcinoma (FDA.gov). |
