On January 12, 2021 Innovent Biologics, Inc. ("Innovent", HKEX: 01801), a world-class biopharmaceutical company that develops, manufactures and commercializes high-quality medicines for the treatment of cancer, metabolic, autoimmune and other major diseases, reported with Eli Lilly and Company ("Lilly",NYSE: LLY) that the National Medical Products Administration (NMPA) of China has accepted the supplemental New Drug Application (sNDA) for TYVYT (sintilimab injection) as second-line therapy for squamous non-small cell lung cancer (sqNSCLC) (Press release, Innovent Biologics, JAN 12, 2021, View Source [SID1234573939]). The application is the third sNDA for TYVYT (sintilimab injection) in NSCLC.

This sNDA was based on a randomized, open-label, Phase 3 clinical trial (ORIENT-3)—evaluating TYVYT (sintilimab injection) as second-line therapy for patients with advanced or recurrent sqNSCLC whose cancer had progressed on first-line platinum-based chemotherapy. Based on the final analysis in the pre-specified full analysis set, TYVYT demonstrated a statistically significant improvement in overall survival (OS) compared with docetaxel, which met the pre-specified superiority criteria. The progression-free survival (PFS) and objective response rate (ORR) were also significantly improved. The safety profile is consistent with previously reported sintilimab studies, and no new safety signals were identified. Detailed data will be released in an upcoming international academic conference or journal.
The principal investigator of ORIENT-3, Professor Yuankai Shi, Associate Dean of Cancer Hospital, Chinese Academy of Medical Sciences, stated: "Lung cancer is the leading cause of cancer death globally, of which NSCLC accounts for 80% to 85%. In the past few decades, drug development of NSCLC has mainly focused on nonsquamous NSCLC, while drug development of squamous NSCLC has been slower due to its unique epidemiological, histopathological and molecular characteristics. In China, the options for second-line immunotherapy are even more limited. The ORIENT-3 study confirmed that the anti-PD-1 monoclonal antibody sintilimab significantly improved OS for the second-line treatment of squamous NSCLC patients, which is of great clinical value. We hope that the positive results of ORIENT-3 can potentially help more squamous NSCLC patients."
"TYVYT (sintilimab injection) is the first anti-PD-1 monoclonal antibody included in the New Catalogue of the National Reimbursement Drug List," said Dr. Hui Zhou, Vice President of Medical Science and Strategy Oncology of Innovent. "In August 2020, the NMPA accepted a new indication application for TYVYT (sintilimab injection) in combination with chemotherapy for first-line treatment of squamous NSCLC. In ORIENT-3 study, sintilimab as second-line monotherapy demonstrated a significantly improved survival benefit for patients with advanced squamous NSCLC, and we look forward to the approval of this indication, to potentially help more patients with this type of lung cancer."
"We are excited about these results, showing TYVYT (sintilimab injection) significantly improved overall survival in this patient population. This study underscores the joint commitment from Lilly and Innovent to provide innovative treatment options to patients with lung cancer," said Dr. Wang Li, Senior Vice President of Lilly China and Head of Lilly China Drug Development and Medical Affairs. "We would like to thank the patients, the investigators, the clinical trial centers and our colleagues from Innovent that are involved in the study. We look forward to working together to potentially bring this new treatment option to patients in China with squamous NSCLC."
About ORIENT-3 Trial
ORIENT-3 is a randomized, open-label, multi-center, Phase 3 clinical trial in China to evaluate the efficacy and safety of TYVYT (sintilimab injection) as second-line therapy for advanced or metastatic sqNSCLC (ClinicalTrials.gov, NCT 03150875). The primary endpoint is overall survival (OS). The secondary endpoints include progression-free survival (PFS) assessed by investigators based on RECIST v1.1, objective response rate (ORR) and safety profile.
A total of 290 patients were enrolled in ORIENT-3 and randomized in a 1:1 ratio to receive either TYVYT (sintilimab injection) 200mg or docetaxel every three weeks. The patients received treatment until radiographic disease progression, unacceptable toxicity or any other conditions that require treatment discontinuation.
About Squamous NSCLC
Lung cancer is a malignancy with the highest morbidity and mortality in China. NSCLC accounts for about 80 to 85 percent of lung cancer. Approximately 70 percent of people with NSCLC have locally advanced or metastatic NSCLC at initial diagnosis, rendering many of those patients with no chance of radical resection. Meanwhile, even after radical surgery, patients still have a high chance of recurrence and eventually die from disease progression. About 30 percent of people with NSCLC in China have tumors of the squamous subtype and there are limited second-line immunotherapies for these patients. In China, there remains a huge unmet medical need.
About TYVYT (Sintilimab Injection)
TYVYT (sintilimab injection), an innovative drug with global quality standards jointly developed in China by Innovent and Eli Lilly and Company, has been granted marketing approval by the NMPA for the treatment of relapsed or refractory classic Hodgkin’s lymphoma after two lines or later of systemic chemotherapy, and is included in the 2019 Guidelines of Chinese Society of Clinical Oncology for Lymphoid Malignancies. TYVYT was included in the National Reimbursement Drug List (NRDL) in 2019 as the historically first PD-1 inhibitor entering in NRDL and the only PD-1 included in the list in that year.
In April 2020, the NMPA accepted the sNDA for TYVYT (sintilimab injection) in combination with ALIMTA (pemetrexed) and platinum chemotherapy as first-line therapy for the treatment of patients with non-squamous non-small cell lung cancer (NSCLC). In May 2020, TYVYT (sintilimab injection) monotherapy met the primary endpoint of overall survival in the Phase 2 ORIENT-2 study as second-line therapy in patients with advanced or metastatic esophageal squamous cell carcinoma. In August 2020, the NMPA accepted the sNDA for TYVYT in combination with GEMZAR (gemcitabine for injection) and platinum chemotherapy as first-line therapy in squamous NSCLC. In September 2020, TYVYT (sintilimab injection) in combination with BYVASDA (bevacizumab biosimilar injection) as a first-line treatment in advanced hepatocellular carcinoma met the predefined primary endpoints of overall survival and progression-free survival in an interim analysis of the Phase 3 ORIENT-32 study. In January 2021, the NMPA accepted the sNDA for TYVYT as second-line therapy for sqNSCLC.
TYVYT (sintilimab injection), is a type of immunoglobulin G4 monoclonal antibody, which binds to PD-1 molecules on the surface of T-cells, block the PD-1 / PD-Ligand 1 (PD-L1) pathway and reactivate T-cells to kill cancer cells. Innovent is currently conducting more than 20 clinical studies with TYVYT (sintilimab injection) to evaluate its safety and efficacy in a wide variety of cancer indications, including more than 10 registrational or pivotal clinical trials. Meanwhile, Innovent is conducting clinical research studies on TYVYT (sintilimab injection) worldwide.
