Toripalimab, sold under the brand name Loqtorzi, is a monoclonal antibody used for the treatment of melanoma and nasopharyngeal carcinoma. [1] [5] Toripalimab is a recombinant humanized programmed cell death protein 1 (PD-1) monoclonal antibody that acts as a checkpoint inhibitor. [6]
In 2018, toripalimab was approved in China for the treatment of unresectable or metastatic melanoma that has failed previous systemic therapy. [6] In October 2023, the US Food and Drug Administration (FDA) approved toripalimab for the first-line treatment of adults with metastatic or recurrent, locally advanced nasopharyngeal carcinoma when used with cisplatin and gemcitabine. [5] [7]
Toripalimab is indicated in combination with cisplatin and gemcitabine for the first-line treatment of adults with metastatic or recurrent locally advanced nasopharyngeal carcinoma. [1] [5] It is also indicated as a single agent for adults with recurrent unresectable or metastatic nasopharyngeal carcinoma with disease progression on or after a platinum-containing chemotherapy. [1] [5]
Efficacy of toripalimab with cisplatin and gemcitabine was evaluated in JUPITER-02 (NCT03581786), a randomized, multicenter, single region, double-blind, placebo-controlled trial in 289 participants with metastatic or recurrent, locally advanced nasopharyngeal carcinoma who had not received previous systemic chemotherapy for recurrent or metastatic disease. [5] Participants were randomized (1:1) to either toripalimab with cisplatin and gemcitabine, followed by toripalimab, or placebo with cisplatin and gemcitabine, followed by placebo. [5]
Efficacy of toripalimab as a single agent was evaluated in POLARIS-02 (NCT02915432), an open-label, multicenter, single country, multicohort trial in 172 participants with unresectable or metastatic nasopharyngeal carcinoma who had received prior platinum-based chemotherapy or had disease progression within six months of completion of platinum-based chemotherapy administered as neoadjuvant, adjuvant, or definitive chemoradiation treatment for locally advanced disease. [5] Participants received toripalimab until disease progression per RECIST v1.1 or unacceptable toxicity. [5]
The FDA granted the application for toripalimab priority review, breakthrough therapy, and orphan drug designations. [5]
In July 2024, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Loqtorzi, intended for the treatment of nasopharyngeal carcinoma and esophageal squamous cell carcinoma. [3] The applicant for this medicinal product is TMC Pharma (EU) Limited. [3] Loqtorzi was approved for medical use in the European Union in September 2024. [3]
Pemetrexed, sold under the brand name Alimta among others, is a chemotherapy medication for the treatment of pleural mesothelioma and non-small cell lung cancer (NSCLC).
Bevacizumab, sold under the brand name Avastin among others, is a monoclonal antibody medication used to treat a number of types of cancers and a specific eye disease. For cancer, it is given by slow injection into a vein (intravenous) and used for colon cancer, lung cancer, ovarian cancer, glioblastoma, hepatocellular carcinoma, and renal-cell carcinoma. In many of these diseases it is used as a first-line therapy. For age-related macular degeneration it is given by injection into the eye (intravitreal).
Sunitinib, sold under the brand name Sutent, is an anti-cancer medication. It is a small-molecule, multi-targeted receptor tyrosine kinase (RTK) inhibitor that was approved by the FDA for the treatment of renal cell carcinoma (RCC) and imatinib-resistant gastrointestinal stromal tumor (GIST) in January 2006. Sunitinib was the first cancer drug simultaneously approved for two different indications.
Panitumumab, sold under the brand name Vectibix, is a fully human monoclonal antibody specific to the epidermal growth factor receptor.
Nasopharyngeal carcinoma (NPC), or nasopharynx cancer, is the most common cancer originating in the nasopharynx, most commonly in the postero-lateral nasopharynx or pharyngeal recess, accounting for 50% of cases. NPC occurs in children and adults. NPC differs significantly from other cancers of the head and neck in its occurrence, causes, clinical behavior, and treatment. It is vastly more common in certain regions of East Asia and Africa than elsewhere, with viral, dietary and genetic factors implicated in its causation. It is most common in males. It is a squamous cell carcinoma of an undifferentiated type. Squamous epithelial cells are a flat type of cell found in the skin and the membranes that line some body cavities. Undifferentiated cells are cells that do not have their mature features or functions.
Treatment of lung cancer refers to the use of medical therapies, such as surgery, radiation, chemotherapy, immunotherapy, percutaneous ablation, and palliative care, alone or in combination, in an attempt to cure or lessen the adverse impact of malignant neoplasms originating in lung tissue.
Amatuximab is a chimeric monoclonal antibody designed for the treatment of cancer. It was developed by Morphotek, Inc.
Nivolumab, sold under the brand name Opdivo, is an anti-cancer medication used to treat a number of types of cancer. This includes melanoma, lung cancer, malignant pleural mesothelioma, renal cell carcinoma, Hodgkin lymphoma, head and neck cancer, urothelial carcinoma, colon cancer, esophageal squamous cell carcinoma, liver cancer, gastric cancer, and esophageal or gastroesophageal junction cancer. It is administered intravenously.
Pembrolizumab, sold under the brand name Keytruda, is a humanized antibody, more specifically a PD-1 Inhibitor, used in cancer immunotherapy that treats melanoma, lung cancer, head and neck cancer, Hodgkin lymphoma, stomach cancer, cervical cancer, and certain types of breast cancer. It is administered by slow intravenous injection.
Durvalumab, sold under the brand name Imfinzi, is an FDA-approved immunotherapy for cancer, developed by Medimmune/AstraZeneca. It is a human immunoglobulin G1 kappa (IgG1κ) monoclonal antibody that blocks the interaction of programmed cell death ligand 1 (PD-L1) with the PD-1 (CD279).
Atezolizumab, sold under the brand name Tecentriq among others, is a monoclonal antibody medication used to treat urothelial carcinoma, non-small cell lung cancer (NSCLC), small cell lung cancer (SCLC), hepatocellular carcinoma and alveolar soft part sarcoma, but discontinued for use in triple-negative breast cancer (TNBC). It is a fully humanized, engineered monoclonal antibody of IgG1 isotype against the protein programmed cell death-ligand 1 (PD-L1).
Sacituzumab govitecan, sold under the brand name Trodelvy by Gilead Sciences, is a Trop-2-directed antibody and topoisomerase inhibitor drug conjugate used for the treatment of metastatic triple-negative breast cancer and metastatic urothelial cancer.

Erdafitinib, sold under the brand name Balversa, is an anti-cancer medication. It is a small molecule inhibitor of fibroblast growth factor receptor (FGFR) used for the treatment of cancer. FGFRs are a subset of tyrosine kinases which are unregulated in some tumors and influence tumor cell differentiation, proliferation, angiogenesis, and cell survival.

Cemiplimab, sold under the brand name Libtayo, is a monoclonal antibody medication for the treatment of squamous cell skin cancer. Cemiplimab belongs to a class of drugs that binds to the programmed death receptor-1 (PD-1), blocking the PD-1/PD-L1 pathway.
Trastuzumab deruxtecan, sold under the brand name Enhertu, is an antibody-drug conjugate consisting of the humanized monoclonal antibody trastuzumab (Herceptin) covalently linked to the topoisomerase I inhibitor deruxtecan. It is licensed for the treatment of breast cancer or gastric or gastroesophageal adenocarcinoma. Trastuzumab binds to and blocks signaling through epidermal growth factor receptor 2 (HER2/neu) on cancers that rely on it for growth. Additionally, once bound to HER2 receptors, the antibody is internalized by the cell, carrying the bound deruxtecan along with it, where it interferes with the cell's ability to make DNA structural changes and replicate its DNA during cell division, leading to DNA damage when the cell attempts to replicate itself, destroying the cell.
Pemigatinib, sold under the brand name Pemazyre, is an anti-cancer medication used for the treatment of bile duct cancer (cholangiocarcinoma). Pemigatinib works by blocking FGFR2 in tumor cells to prevent them from growing and spreading.
