Coherus BioSciences, Shanghai Junshi Biosciences Report FDA Granted Orphan Drug Designation For Torpalimab For Treatment Of Esophageal Cancer

Coherus BioSciences, Inc. ((&ldquo, Coherus&rdquo, , NASDAQ:CHRS) and Shanghai Junshi Biosciences Co., Ltd. ("Junshi Biosciences", HKEX: 1877; SSE: 688180) announced today that the United States Food and Drug Administration ("FDA") has granted Orphan Drug Designation (ODD) for toripalimab for the treatment of esophageal cancer. Orphan drug designation is granted to drugs and biologics intended to treat rare diseases with a patient population less than 200,000 in the U.S. The designation provides incentives to advance development and commercialization of rare disease drugs.

Esophageal cancer ("EC") is a malignant tumor originating in the inner lining of the esophagus. Esophageal squamous cell carcinoma ("ESCC") and adenocarcinoma are the two main subtypes of esophageal cancer. EC is rare in the United States, with approximately 19,000 newly diagnosed cases and 15,000 deaths annually, according to estimates from the American Cancer Society. The prognosis of patients with advanced EC is poor, with five-year survival rates of less than 20%.

"Esophageal squamous cell carcinoma is an aggressive cancer, and patients need new and better treatment options. We plan to work closely with our partner, Junshi Biosciences, to submit a BLA supplement for toripalimab for this indication in 2022," said Denny Lanfear, CEO of Coherus.

In September, Coherus and Junshi Biosciences announced results of the Phase 3 clinical trial, JUPITER-06, a randomized, double blind, placebo-controlled study evaluating toripalimab in combination with chemotherapy as a first-line therapy for patients with advanced or metastatic ESCC. The study met the co-primary endpoints with statistically significant and clinically meaningful improvements in progression free survival (PFS) and overall survival (OS) for patients treated with the toripalimab and chemotherapy combination, compared to chemotherapy alone. In 2022, Coherus and Junshi Biosciences are planning to submit a biologics license application ("BLA") supplement to the FDA for toripalimab in combination with platinum-based chemotherapy for the first-line treatment of advanced or metastatic ESCC. A BLA for toripalimab for advanced recurrent or metastatic nasopharyngeal carcinoma is currently under priority review by the FDA with a target action date of April 2022.
