– Coherus and Junshi Biosciences to meet with US FDA to discuss 1L NSCLC BLA supplement submission –

SHANGHAI, China and REDWOOD CITY, CA, USA I December 13, 2021 I Shanghai Junshi Biosciences Co., Ltd. (“Junshi Biosciences”, HKEX: 1877; SSE: 688180) and Coherus BioSciences, Inc. (“Coherus”, Nasdaq: CHRS), today announced positive results of an interim analysis of overall survival from the pivotal study “CHOICE-01” (NCT03856411), a randomized, double-blind, placebo-controlled Phase 3 clinical trial evaluating toripalimab plus standard-of-care chemotherapy as the first-line treatment of advanced squamous or non-squamous non-small cell lung cancer (“NSCLC”). This interim analysis demonstrated a statistically significant improvement in overall survival, crossing the prespecified efficacy boundary, in patients treated with toripalimab plus chemotherapy. This treatment effect was observed notwithstanding the effects of active crossover to toripalimab at disease progression for patients in the control (placebo plus chemotherapy) arm. As previously reported at the 2021 World Conference on Lung Cancer (WCLC), the study also met the primary endpoint of progression free survival (PFS) per RECIST v1.1 for the toripalimab arm as compared to chemotherapy alone.

Junshi Biosciences and Coherus plan to submit the CHOICE-01 results for publication and request a meeting with the United States Food and Drug Administration (“FDA”) to discuss the submission of a Biologics License Application (“BLA”) supplement for toripalimab in combination with chemotherapy for the first-line treatment of advanced NSCLC. The BLA for toripalimab in combination with gemcitabine and cisplatin for the first-line treatment for patients with advanced recurrent or metastatic nasopharyngeal carcinoma (“NPC”) and toripalimab monotherapy for the second-line or above treatment of recurrent or metastatic NPC after platinum-containing chemotherapy is currently under priority review by the FDA.

“The achievement of an overall survival benefit in non-small cell lung cancer patients by toripalimab is a watershed event in the strategic transformation of Coherus and validates the role of toripalimab as the foundation of our immuno-oncology pipeline,” said Denny Lanfear, CEO of Coherus. “Toripalimab has once again delivered positive progression free survival and overall survival clinical data in a first-line setting. We will now work closely with our partners at Junshi Biosciences to engage the FDA on BLA supplement filing strategies for first-line treatment of non-small cell lung cancer. We also look forward to initiating future studies combining toripalimab with a series of complementary immuno-oncology agents to advance patient care and outcomes in oncology.”

“The results of CHOICE-01, demonstrating improvements in overall survival, confirm that toripalimab can deliver significant benefits to patients receiving first-line treatment for non-small cell lung cancer,” said Dr. Patricia Keegan, Chief Medical Officer of Junshi Biosciences. “With a consistently strong record of positive efficacy and safety accumulating as data read out from studies across multiple tumor types, we are working to register toripalimab for a broad array of indications in China and the United States. In 2022, we look forward to clinical data from additional Phase 3 studies in NSCLC, small cell lung cancer, triple negative breast cancer, and hepatocellular cancer.”

About CHOICE-01
A total of 465 treatment-naive advanced NSCLC patients (220 squamous and 245 non-squamous) were randomized (2:1): 309 patients to the toripalimab plus chemotherapy arm and 156 to the placebo plus chemotherapy arm. The primary endpoint was PFS assessed by the investigator. Secondary endpoints included PFS assessed by a blinded independent review committee (BIRC), overall survival (OS), objective response rate (ORR) and duration of response (DoR). Patients in the placebo plus chemotherapy arm were actively crossed-over to toripalimab treatment at disease progression. The addition of toripalimab to standard first-line chemotherapy in patients with advanced NSCLC showed a manageable safety profile with no new safety signals observed.

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, 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 4 approved indications for toripalimab in China:

  1. second-line treatment of unresectable or metastatic melanoma;
  2. recurrent or metastatic nasopharyngeal carcinoma (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.

The first three indications have been included in the National Reimbursement Drug List (NRDL) (2021 Edition). Toripalimab is the only anti-PD-1 monoclonal antibody included in the NRDL for the first and second indications (melanoma and NPC).

In addition, two supplemental New Drug Applications (NDAs) for toripalimab were accepted by the National Medical Products Administration (NMPA) for review in China:

  • first-line treatment of patients with advanced or metastatic esophageal squamous cell carcinoma (ESCC).
  • in combination with chemotherapy as the first-line treatment of patients with advanced or metastatic non-small cell lung cancer (NSCLC) with no EGFR or ALK tumor aberrations.

In the United States, the FDA has granted priority review for the toripalimab BLA for the treatment of recurrent or metastatic NPC, an aggressive head and neck tumor which has no FDA-approved immuno-oncology treatment options. Earlier, the FDA granted Breakthrough Therapy designation for toripalimab in combination with chemotherapy for the first-line treatment of recurrent or metastatic NPC as well as for toripalimab monotherapy in the second or third-line treatment of recurrent or metastatic NPC. Additionally, the FDA has granted Fast Track designation for toripalimab for the treatment of mucosal melanoma and orphan drug designation for the treatment of esophageal cancer, 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 other cancer types.
