Coherus and Junshi Biosciences Announce Results from Phase 3 Study of Toripalimab Published in September Issue of Nature Medicine
Coherus BioSciences (Nasdaq: CHRS) and Shanghai Junshi Biosciences announced significant findings from the JUPITER-02 clinical trial, published in Nature Medicine. The Phase 3 trial demonstrated that toripalimab combined with standard chemotherapy improved progression-free survival (PFS) in patients with advanced nasopharyngeal carcinoma (NPC), showing a median PFS of 11.7 months versus 8.0 months with chemotherapy alone. While overall survival data is not yet mature, a 40% reduction in death risk was noted. A biologics license application has been submitted to the FDA for approval.
- Toripalimab plus chemotherapy showed improved PFS (11.7 vs 8.0 months) in NPC patients.

- Study validates toripalimab's potential as a new standard-of-care for advanced NPC.
- Overall survival data from the study is not yet mature.
- Increased incidence of immune-related adverse events (39.7% vs 18.9%) in toripalimab arm.
- Toripalimab plus standard chemotherapy demonstrates improvement in PFS in first-line advanced nasopharyngeal carcinoma -
REDWOOD CITY, Calif., and SHANGHAI, China, Sept. 15, 2021 (GLOBE NEWSWIRE) -- Coherus BioSciences, Inc. (“Coherus”, Nasdaq: CHRS) and Shanghai Junshi Biosciences Co., Ltd (“Junshi Biosciences”, HKEX: 1877; SSE: 688180) today announced publication of a cover article in the September issue of Nature Medicine featuring clinical data from the pivotal study “JUPITER-02”, a randomized, double-blind, placebo-controlled Phase 3 clinical trial evaluating toripalimab plus chemotherapy for the first-line treatment of recurrent or metastatic nasopharyngeal carcinoma (NPC).
Titled Toripalimab or placebo plus chemotherapy as first-line treatment in advanced nasopharyngeal carcinoma: a multicenter randomized phase 3 trial, the paper highlights that the addition of toripalimab to standard of care gemcitabine-cisplatin (GP) chemotherapy as a first-line treatment for patients with recurrent or metastatic NPC provided superior progression free survival (PFS) compared to GP alone [median PFS of 11.7 vs 8.0 months, hazard ratio (HR) = 0.52 (
“There are currently no PD-1 blocking antibodies approved for NPC in the United States. We are pleased that this study has been selected for cover article publication in this highly-respected journal,” said Dr. Patricia Keegan, Chief Medical Officer of Junshi Biosciences. “This is a strong signal that further validates the potential advance that toripalimab in combination with chemotherapy would represent as a new standard-of-care first-line therapy for patients with advanced NPC, an aggressive and difficult-to-treat cancer.”
A biologics license application has been submitted to the U.S. Food and Drug Administration (“FDA”) for toripalimab in combination with gemcitabine and cisplatin for first-line treatment for patients with advanced recurrent or metastatic NPC and toripalimab monotherapy for second-line or above treatment of recurrent or metastatic NPC after platinum-containing chemotherapy.
About JUPITER-02
The JUPITER-02 Study (ClinicalTrials.gov identifier: NCT03581786) is a randomized, double-blind, placebo-controlled, international multi-center Phase 3 clinical trial comparing the efficacy and safety of toripalimab versus placebo in combination with Gemcitabine/Cisplatin, as a first-line treatment for patients with recurrent or metastatic nasopharyngeal carcinoma. Professor Ruihua Xu from Sun Yat-sen University Cancer Centre is the lead principal investigator of the study. The largest Phase 3 clinical trial to date evaluating a checkpoint inhibitor plus chemotherapy for the first-line treatment of recurrent or metastatic nasopharyngeal carcinoma, JUPITER-02 was conducted in mainland China, Taiwan and Singapore and enrolled a total of 289 patients.
About Toripalimab
Toripalimab is an anti-PD-1 monoclonal antibody developed for its ability to block PD-1 interactions with its ligands, PD-L1 and PD-L2, and for enhanced receptor internalization (endocytosis function). Blocking PD-1 interactions with PD-L1 and PD-L2 is thought to recharge the immune system’s ability to attack and kill tumor cells. More than thirty company-sponsored toripalimab clinical studies covering more than fifteen indications have been conducted globally, including in China and the United States. Ongoing or completed pivotal clinical trials are evaluating the safety and efficacy of toripalimab for a broad range of tumor types including cancers of the lung, nasopharynx, esophagus, stomach, bladder, breast, liver, kidney and skin.
In China, toripalimab was the first domestic anti-PD-1 monoclonal antibody approved for marketing (approved in China as TUOYI®). On December 17, 2018, toripalimab was granted a conditional approval by the National Medical Products Administration (NMPA) for the second-line treatment of unresectable or metastatic melanoma. In December 2020, toripalimab was successfully included in the updated National Reimbursement Drug List. In February 2021, the NMPA granted a conditional approval to toripalimab for the treatment of patients with recurrent or metastatic nasopharyngeal carcinoma (NPC) after failure of at least two lines of prior systemic therapy. In April 2021, NMPA granted a conditional approval to toripalimab for the treatment of patients with locally advanced or metastatic urothelial carcinoma who failed platinum-containing chemotherapy or progressed within 12 months of neoadjuvant or adjuvant platinum-containing chemotherapy. In addition, two supplemental NDAs for toripalimab in combination with chemotherapy for the first-line treatment of patients with advanced, recurrent or metastatic NPC or for the first-line treatment of patients with advanced, or metastatic esophageal squamous cell carcinoma were accepted by the NMPA for review in February and July 2021 respectively.
In the United States, the first toripalimab BLA has been submitted to the FDA for the treatment of recurrent or metastatic NPC. The FDA has granted Breakthrough Therapy designations for toripalimab in combination with chemotherapy for the 1st line treatment of recurrent or metastatic NPC and for toripalimab monotherapy in the 2nd line and subsequent treatment of recurrent or metastatic NPC. There are currently no PD-1 blocking antibodies approved for use in NPC in the United States. Additionally, FDA has granted Fast Track designation for toripalimab for the treatment of mucosal melanoma and orphan drug designation for NPC, mucosal melanoma and soft tissue sarcoma. Earlier in 2021 Coherus in-licensed rights to develop and commercialize toripalimab in the United States and Canada. Coherus and Junshi Biosciences plan to file additional toripalimab BLAs with the FDA over the next three years for multiple rare cancers and highly prevalent cancers.
