Junshi Biosciences and Coherus BioSciences Announce Collaboration to Co-Develop Anti-PD-1 Antibody, Toripalimab, in U.S. and Canada

• Junshi Biosciences to receive up to an aggregate of US$1.11 billion of upfront payment, exercise fee and milestone payments from Coherus for the grant of the license of toripalimab and the two option programs (if exercised) in US and Canada
• The first toripalimab BLA to be filed with the US FDA for nasopharyngeal carcinoma later this year

SHANGHAI, China, Feb. 01, 2021 (GLOBE NEWSWIRE) — Junshi Biosciences (HKEX: 1877; SSE: 688180), an innovation-driven biopharmaceutical company dedicated to the discovery, development and commercialization of novel therapies, today announced a collaboration with Coherus BioSciences, Inc. (“Coherus”, Nasdaq: CHRS) for the development and commercialization of toripalimab, Junshi Biosciences’ anti-PD-1 antibody, in the United States and Canada.

Under the terms of the agreement, Junshi Biosciences will receive up to an aggregate of US$1.11 billion of upfront payment, exercise fee and milestone payments from Coherus for the grant of the license of toripalimab and the two option programs (if exercised). Junshi Biosciences and Coherus will co-develop toripalimab, and Coherus will be responsible for all commercial activities in US and Canada. Junshi Biosciences has also granted Coherus options to JS006 (an anti-TIGIT antibody) and JS018-1 (a next generation engineered IL-2 cytokine), as well as first negotiation rights to two early-stage checkpoint inhibitor antibodies.

“We believe Coherus is the ideal partner for us in North America. Their commercial team has demonstrated remarkable ability to gain significant share of the oncology market against entrenched large competitors,” said Dr. Ning LI, CEO of Junshi Biosciences. “Toripalimab could be the first marketed Chinese anti-PD-1 antibody in the overseas market. The collaboration with Coherus will be a critical step to build up our global commercial network. We look forward to working closely with Coherus to establish toripalimab’s position in the United States and Canadian markets in order to provide patients with affordable high-quality innovative care.”

“Toripalimab has a compelling clinical profile with impressive efficacy and safety, and we are thrilled to collaborate with Junshi Biosciences to deliver patient benefit in the United States and Canada,” said Denny Lanfear, CEO of Coherus. “Our mission has always been to increase patient access to important medicines and to deliver significant health care system savings. This transaction builds on that mission to include the rapidly growing checkpoint inhibitor market, which is expected to exceed US$25 billion by 2025, and provides us the essential backbone drug for development of next-generation combination therapies.”

More than 2,100 patients have received toripalimab treatment in clinical trials, and toripalimab is approved for second-line treatment of unresectable or metastatic melanoma in China where it is marketed by Junshi Biosciences and is included on the National Reimbursement Drug List (NRDL). Over the next three years, significant data are expected to read out from the extensive registrational development program, which includes 15 ongoing or completed international/domestic multi-center pivotal clinical trials evaluating toripalimab in multiple treatment settings for a broad range of solid tumor types including cancers of the lung, nasopharynx, esophagus, stomach, bladder, breast, liver, kidney and skin.

The United States Food and Drug Administration (FDA) has granted a breakthrough therapy designation to toripalimab for nasopharyngeal carcinoma (NPC), and the first toripalimab Biologics License Application (BLA) is expected to be filed with the FDA for this indication later this year. Additionally, FDA has granted Fast Track status for the development of toripalimab for the treatment of mucosal melanoma, and orphan drug designation for NPC, mucosal melanoma and soft tissue sarcoma. Junshi Biosciences and Coherus plan to file additional toripalimab BLAs with the FDA over the next two years for several rare and highly prevalent cancers, including non small cell lung cancer (NSCLC).

As part of the collaboration, Coherus has also acquired options or first negotiation rights to four of Junshi Biosciences’ novel oncology molecules. The Companies may develop toripalimab in combination with one or more of these four compounds, and potentially with other cancer drugs:

• An option to JS006, an antibody targeting TIGIT, a clinically validated immune inhibitory checkpoint. Anti-TIGIT antibodies have demonstrated significant synergistic anti-tumor activity in combination with anti-PD-1 antibodies. JS006 is expected to enter global clinical development later this year. The option term expires prior to initiation of Phase 2 development.
• An option to JS018-1, a next-generation engineered IL-2 cytokine designed to inhibit stimulation of regulatory T cells while retaining stimulatory activity on effector T-cells and natural killer (“NK”) cells. The option term expires prior to initiation of Phase 2 development.
• First negotiation rights to two undisclosed early-stage novel oncology programs directed against immune checkpoint molecules.

Under the terms of the agreement, Junshi Biosciences will receive up to an aggregate of US$1.11 billion of upfront payment, exercise fee and milestone payments from Coherus for the grant of the license of toripalimab and the two option programs (if exercised) in the United States and Canada.

Junshi Biosciences will grant Coherus exclusive rights to toripalimab in the United States and Canada as well as options in these territories to Junshi Biosciences’ JS006 and JS018-1. Coherus will also have first negotiation rights to two undisclosed preclinical immuno-oncology programs. Junshi Biosciences will receive an upfront payment of US$150 million. For toripalimab, Junshi Bioscience will receive 20% royalty on the annual net sales of toripalimab and up to an aggregate $380 million in one-time payments for the achievement of various milestones. For JS006 and JS108-1, Junshi Biosciences will receive an opt-in payment of $35 million per program. Additionally, for each program, Junshi Biosciences will receive 18% royalty on the annual net sales and up to an aggregate $255 million for the achievement of various milestones. The Companies will collaborate on the development of toripalimab and other licensed compounds, and Coherus will pay for a portion of these co-development activities up to a maximum of US$25 million per licensed compound per year.

About toripalimab (TUOYI®)
Toripalimab is the first domestic anti-PD-1 monoclonal antibody to obtain a marketing approval in China. So far, more than thirty company-sponsored clinical studies covering more than fifteen indications have been conducted globally, including in China and the United States. On December 17, 2018, Toripalimab obtained a conditional approval from the NMPA for the second-line treatment of patients with unresectable or metastatic melanoma. Supplemental NDAs of toripalimab for the third-line treatment of recurrent/metastatic nasopharyngeal carcinoma and second-line treatment of metastatic urothelial carcinoma were accepted by the NMPA in April and May 2020, respectively. Both supplemental NDAs received priority review designations from the NMPA in July 2020. In December 2020, toripalimab was included in the National Reimbursement Drug List (NRDL) for the treatment of melanoma by the China National Healthcare Security Administration (NHSA).

In the United States, the FDA has granted toripalimab breakthrough therapy designation for the treatment of recurrent/metastatic nasopharyngeal carcinoma, Fast Track designation for mucosal melanoma, and orphan drug designation for the treatment of nasopharyngeal carcinoma, mucosal melanoma and soft tissue sarcoma.
