SAN FRANCISCO, and SUZHOU, China, June 22, 2021 /PRNewswire/ — Innovent Biologics, Inc. (“Innovent”) (HKEX: 01801), a world-class biopharmaceutical company that develops, manufactures and commercializes high quality medicines for the treatment of oncology, metabolic, autoimmune and other major diseases, today announced that the Phase 3 ORIENT-15 study met the predefined overall survival primary endpoint. ORIENT-15 is a global randomized, double-blind, multi-center clinical study evaluating sintilimab in combination with chemotherapy (cisplatin plus paclitaxel or cisplatin plus 5-fluorouracil [5-FU]) for the first-line treatment of patients with unresectable, locally advanced recurrent or metastatic esophageal squamous cell carcinoma (ESCC).
Based on an interim analysis conducted by the Independent Data Monitoring Committee (IDMC), sintilimab in combination with chemotherapy demonstrated a statistically significant and clinically meaningful improvement in the primary endpoint of overall survival (OS) compared to placebo in combination with chemotherapy regardless of PD-L1 expression status. The safety profile of sintilimab in this study was consistent with that observed in previously reported studies of sintilimab, and no additional safety signals were identified. These results will be presented at an upcoming medical meeting.
The principal investigator of the ORIENT-15 study, Prof. Shen Lin from Peking University Cancer Hospital and Institute stated, “More than half of new and fatal cases of esophageal cancer in the world occur in China every year. In China, esophageal cancer is the fifth most commonly diagnosed cancer and the fourth leading cause of death from cancer, and squamous cell carcinoma (ESCC) is the predominant histologic type. Treatment options for people with ESCC are limited. Chemotherapy is currently the main treatment for ESCC and, in recent years, immunotherapy has brought new hope in the treatment of this type of cancer, with some PD-1 inhibitors receiving approval as a second-line treatment for patients with ESCC in China. We are encouraged by these interim results of the ORIENT-15 study which demonstrated that sintilimab in combination with chemotherapy prolonged overall survival in the first-line treatment of patients with ESCC, regardless of PD-L1 status.”
Dr. Zhou Hui, Senior Vice President of Clinical Development of Innovent, stated: “The treatment options for locally advanced or metastatic ESCC are limited and represent a significant unmet clinical need. ORIENT-15 is the largest clinical study of sintilimab conducted by Innovent to date. Despite the COVID-19 pandemic, the joint effort of the study’s investigators and broader team have enabled us to reach this milestone. We would like to express our sincere gratitude to all the patients who participated in the ORIENT-15 study. We hope these results can help to provide a new treatment option for patients with ESCC.”
About the ORIENT-15 Study
ORIENT-15 is a global randomized, double-blind, multi-center Phase 3 clinical study evaluating sintilimab in combination with chemotherapy (cisplatin plus paclitaxel or cisplatin plus 5-fluorouracil [5-FU]), compared to placebo in combination with chemotherapy, for the first-line treatment of unresectable, locally advanced recurrent or metastatic esophageal squamous cell carcinoma (ClinicalTrials.gov, NCT03748134). At the time of interim analysis, a total of 659 eligible patients were enrolled and randomly assigned into the experimental group or control group in a 1:1 ratio. Patients were enrolled regardless of PD-L1 status. The primary endpoints included overall survival in all randomized patients and overall survival in PD-L1 positive (defined as CPS ≥10) patients.
About Esophageal Squamous Cell Carcinoma (ESCC)
Esophageal cancer is one of the most common malignant tumors worldwide that begins in the inner layer (mucosa) of the esophagus, which connects the throat to the stomach. Based on GLOBOCAN 2020 estimates, approximately 600,000 new cases of esophageal cancer are diagnosed and approximately 540,000 deaths result from the disease globally. Esophageal cancer is the seventh most commonly diagnosed cancer and the sixth leading cause of death from cancer worldwide. More than half of new and fatal cases of esophageal cancer in the world occur in China. In China, it is estimated there were approximately 320,000 new cases of esophageal cancer diagnosed and approximately 300,000 deaths resulting from the disease in 2020. Esophageal cancer is the fifth most commonly diagnosed cancer and the fourth leading cause of death from cancer in China, which has a five-year survival rate of only 30 percent.
The two main types of esophageal cancer are squamous cell carcinoma (SCC) and adenocarcinoma. In China, SCC is the predominant histologic type – accounting for more than 90 percent of all esophageal cancer. Currently, first-line standard systemic therapy in China is chemotherapy based on platinum drugs for unresectable, locally advanced recurrent or metastatic ESCC. There have been a few PD-1 inhibitors recently approved for the second-line treatment of patients with ESCC.
Sintilimab, marketed as TYVYT® (sintilimab injection) in China, is an innovative PD-1 inhibitor with global quality standards jointly developed by Innovent and Eli Lilly and Company. Sintilimab is an immunoglobulin G4 monoclonal antibody, which binds to PD-1 molecules on the surface of T-cells, blocks the PD-1 / PD-Ligand 1 (PD-L1) pathway, and reactivates T-cells to kill cancer cells. Innovent is currently conducting more than 20 clinical studies of sintilimab to evaluate its safety and efficacy in a wide variety of cancer indications, including more than 10 registrational or pivotal clinical trials.
In China, sintilimab has been approved for three indications, including:
- The treatment of relapsed or refractory classic Hodgkin’s lymphoma after two lines or later of systemic chemotherapy
- In combination with pemetrexed and platinum chemotherapy, for the first-line treatment of nonsquamous non-small cell lung cancer
- In combination with gemcitabine and platinum chemotherapy, for the first-line treatment of squamous non-small cell lung cancer
Additionally, Innovent currently has regulatory submissions under review in China for sintilimab:
- In combination with BYVASDA® (bevacizumab injection) for the first-line treatment of hepatocellular carcinoma
- The second-line treatment of squamous non-small cell lung cancer
Innovent also has two clinical studies that have met primary endpoint for sintilimab:
- in combination with cisplatin plus paclitaxel or cisplatin plus 5-fluorouracil for the first-line treatment of esophageal squamous cell carcinoma
- The second-line treatment for esophageal squamous cell carcinoma
In May 2021, the U.S. FDA accepted for review the Biologics License Application (BLA) for sintilimab in combination with pemetrexed and platinum chemotherapy for the first-line treatment of nonsquamous non-small cell lung cancer.
Sintilimab was included in China’s National Reimbursement Drug List (NRDL) in 2019 as the first PD-1 inhibitor and the only PD-1 included in the list in that year.
