In 2018, toripalimab was approved in China for the treatment of unresectable or metastatic melanoma that has failed previous systemic therapy.[4] 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.[3][5]

Medical uses

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][3] 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][3]

History

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.[3] Participants were randomized (1:1) to either toripalimab with cisplatin and gemcitabine, followed by toripalimab, or placebo with cisplatin and gemcitabine, followed by placebo.[3]

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.[3] Participants received toripalimab until disease progression per RECIST v1.1 or unacceptable toxicity.[3]

The FDA granted the application for toripalimab priority review, breakthrough therapy, and orphan drug designations.[3]
