Junshi Biosciences and Coherus Announce Positive Final Overall Survival Results of JUPITER-02, a Phase 3 Clinical Trial Evaluating Toripalimab as Treatment for Recurrent or Metastatic Nasopharyngeal Carcinoma

- Final overall survival analysis of the JUPITER-02 trial shows first-line treatment with toripalimab plus chemotherapy significantly prolongs survival in patients with advanced NPC -

SHANGHAI, China and REDWOOD CITY, Calif., Feb. 15, 2023 (GLOBE NEWSWIRE) -- Shanghai Junshi Biosciences Co., Ltd (“Junshi Biosciences”, HKEX: 1877; SSE: 688180) and Coherus BioSciences, Inc. (“Coherus”) today announced positive results of a final analysis of overall survival (“OS”) from the pivotal study JUPITER-02 (NCT03581786), a randomized, double-blind, placebo-controlled Phase 3 clinical trial evaluating toripalimab in combination with gemcitabine and cisplatin as the first-line treatment for patients with recurrent or metastatic nasopharyngeal carcinoma (“NPC”). This final analysis demonstrated a statistically significant and clinically meaningful improvement in OS in NPC patients treated with toripalimab plus chemotherapy compared to chemotherapy alone. These data are being submitted for presentation at an upcoming medical meeting.

“With the ongoing accumulation of data from the JUPITER-02 trial, we are thrilled to observe toripalimab gain more ground for becoming the preferred treatment for advanced NPC,” said Dr. Patricia Keegan, Chief Medical Officer of Junshi/TopAlliance Biosciences. “Compared to chemotherapy alone, a combination containing the immune checkpoint inhibitor, toripalimab, clearly has the potential to bring unprecedented changes to the extension of life in patients with NPC. We are looking forward to bringing this promising therapy to patients around the world.”

“In the pivotal JUPITER-02 trial, toripalimab has demonstrated a statistically significant and clinically meaningful overall survival benefit for patients with advanced NPC, an aggressive head and neck tumor with no current FDA-approved treatment options,” said Rosh Dias, M.D., Coherus’ Chief Medical Officer. “These mature overall survival data continue to demonstrate the benefit of toripalimab in the treatment of NPC patients, further building upon the data published in Nature Medicine and presented at the 2021 plenary session at the ASCO annual meeting, and clearly show that toripalimab has the potential to become the new standard-of-care for NPC patients, once approved. We look forward to sharing these data with the oncology community at an upcoming medical meeting.”

The FDA has granted Breakthrough Therapy designations and priority review for the toripalimab Biologics License Application (“BLA”) for use in combination with gemcitabine and cisplatin as first-line treatment for patients with advanced recurrent or metastatic NPC and for toripalimab monotherapy for the second-line or later treatment of recurrent or metastatic NPC after platinum-containing chemotherapy. Recurrent or metastatic NPC is an aggressive head and neck tumor which has no FDA-approved treatment options.

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 promotes 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 by Junshi Biosciences, including in China, the United States, Southeast Asia, and European countries. Ongoing or completed pivotal clinical trials evaluating the safety and efficacy of toripalimab cover 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®). Currently, there are six approved indications for toripalimab in China:

  1. unresectable or metastatic melanoma after failure of standard systemic therapy;
  2. recurrent or metastatic NPC after failure of at least two lines of prior systemic therapy;
  3. locally advanced or metastatic urothelial carcinoma that failed platinum-containing chemotherapy or progressed within 12 months of neoadjuvant or adjuvant platinum-containing chemotherapy;
  4. in combination with cisplatin and gemcitabine as the first-line treatment for patients with locally recurrent or metastatic NPC;
  5. in combination with paclitaxel and cisplatin in first-line treatment of patients with unresectable locally advanced/recurrent or distant metastatic esophageal squamous cell carcinoma ("ESCC");
  6. in combination with pemetrexed and platinum as the first-line treatment in EGFR mutation-negative and ALK mutation-negative, unresectable, locally advanced or metastatic non-squamous non-small cell lung cancer (“NSCLC”).

The first three indications have been included in the National Reimbursement Drug List (NRDL) (2022 Edition). Toripalimab is the only anti-PD-1 monoclonal antibody included in the NRDL for treatment of melanoma.

Founded in December 2012, Junshi Biosciences (HKEX: 1877; SSE: 688180) is an innovation-driven biopharmaceutical company dedicated to the discovery, development, and commercialization of innovative therapeutics. The company has established a diversified R&D pipeline comprising over 50 drug candidates, with five therapeutic focus areas covering cancer, autoimmune, metabolic, neurological, and infectious diseases. Junshi Biosciences was the first Chinese pharmaceutical company that obtained marketing approval for anti-PD-1 monoclonal antibody in China. Its first-in-human anti-BTLA monoclonal antibody for the treatment of various cancers was the first in the world to be approved for clinical trials by the FDA and NMPA and has since entered Phase Ib/II trials in both China and the US. Its anti-PCSK9 monoclonal antibody was the first in China to be approved for clinical trials by the NMPA.

In the face of the pandemic, Junshi Biosciences’ response was strong and immediate, joining forces with Chinese and international scientific research institutions and enterprises to develop an arsenal of drug candidates to combat COVID-19, taking the initiative to shoulder the social responsibility of Chinese pharmaceutical companies by prioritizing and accelerating COVID-19 R&D. Among the many drug candidates is JS016 (etesevimab), China’s first neutralizing fully human monoclonal antibody against SARS-CoV-2 and the result of the combined efforts of Junshi Biosciences, the Institute of Microbiology of the Chinese Academy of Science and Lilly. JS016 administered with bamlanivimab has been granted Emergency Use Authorizations (EUA) in over 15 countries and regions worldwide. As of December 3 2021, over 700,000 patients have been treated with bamlanivimab or bamlanivimab and etesevimab, potentially preventing more than 35,000 hospitalizations and at least 14,000 deaths. Meanwhile, VV116, a new oral nucleoside analog anti-SARS-CoV-2 drug designed to hinder virus replication, has been approved for marketing in China and Uzbekistan. The JS016 and VV116 programs are a part of the company’s continuous innovation for disease control and prevention of the global pandemic.

Junshi Biosciences has more than 3,100 employees in the United States (San Francisco and Maryland) and China (Shanghai, Suzhou, Beijing, Guangzhou, etc). For more information, please visit: http://junshipharma.com.
