SHANGHAI, China and CAMBRIDGE, Mass., May 18, 2023 (GLOBE NEWSWIRE) -- Zai Lab Limited (NASDAQ: ZLAB; HKEX: 9688) today announced that the Center for Drug Evaluation (CDE) of China’s National Medical Products Administration (NMPA) has granted priority review to repotrectinib for the treatment of adult patients with locally advanced or metastatic ROS1-positive non-small-cell lung cancer (NSCLC).
“The CDE’s decision to grant priority review to repotrectinib underscores repotrectinib as a potential next-generation best-in-class treatment for ROS1-positive NSCLC in both TKI-naïve and pretreated patients in China,” said Rafael G. Amado, M.D., President, Head of Global Oncology Research and Development at Zai Lab. “We thank the agency for their commitment and continued support to patients in need, and we look forward to our continued partnership with regulatory authorities in China to bring this important medicine to patients in need as soon as possible.”
Priority review was established in China to encourage innovative drug development with significant clinical value and urgent clinical need. It is implemented under the Drug Registration Regulation (Bureau Order 27) and the Working Procedure for Priority Review and Approval of Drug Marketing Authorization (Interim, NMPA 2020 No. 82) effective on July 1, 2020, and July 7, 2020, respectively. According to the regulation and guidance, the regulatory authority will prioritize the evaluation resources for applications under priority review to expedite the review and approval timelines.
Repotrectinib is a next-generation tyrosine kinase inhibitor targeting the ROS1 and NTRK oncogenic drivers of advanced solid tumors, including NSCLC. Patients with tumor harboring ROS1 and NTRK gene fusions treated with approved targeted therapies often develop resistance mutations, limiting binding of these drugs to their target, eventually leading to tumor progression. Repotrectinib is the first next-generation TKI for ROS1-positive metastatic NSCLC, uniquely designed to address key drivers of disease progression. Zai Lab and Turning Point Therapeutics, Inc. (Turning Point Therapeutics, acquired by Bristol Myers Squibb) are studying repotrectinib in TRIDENT-1, a registrational Phase 1/2 study in adults, and CARE, a Phase 1/2 study in pediatric patients. Repotrectinib has shown robust antitumor activity and durable responses among TKI-naïve and pre-treated patients. Zai Lab is enrolling patients in the registrational TRIDENT-1 study in Greater China (Mainland China, Hong Kong, Taiwan, and Macau), while Turning Point Therapeutics is enrolling patients in other regions of the world.
Repotrectinib has been granted three Breakthrough Therapy Designations from the U.S. Food and Drug Administration in: ROS1-positive metastatic NSCLC patients who have not been treated with a ROS1 TKI; ROS1-positive metastatic NSCLC patients who have previously been treated with a ROS1 TKI and who have not received prior platinum-based chemotherapy; and patients with advanced solid tumors that have an NTRK gene fusion who have progressed following treatment with one or two prior TRK TKIs, with or without prior chemotherapy, and have not had satisfactory alternative treatments. Additionally, repotrectinib was previously granted four Fast-Track designations in ROS1-positive advanced NSCLC patients who are ROS1 TKI naïve; ROS1-positive advanced NSCLC patients who have been previously treated with one prior line of platinum-based chemotherapy and one prior ROS1 TKI; ROS1-positive advanced NSCLC patients pretreated with one prior ROS1 TKI without prior platinum-based chemotherapy; and NTRK-positive patients with advanced solid tumors who have progressed following treatment with at least one prior line of chemotherapy and one or two prior TRK TKIs and have not had satisfactory alternative treatments. Repotrectinib was also granted an Orphan Drug designation in 2017.

Zai Lab has an exclusive license agreement with Turning Point Therapeutics to develop and commercialize repotrectinib in Greater China.
About Non-Small Cell Lung Cancer in China
Lung cancer is both the most commonly diagnosed cancer type and the leading cause of cancer death in China. The incidence of lung cancer in China in 2020 was 815,563 cases, with 714,699 deaths.1 NSCLC accounts for approximately 85% of lung cancer, and about 70% of NSCLC is locally advanced or metastatic at initial diagnosis. In China, ROS1 rearrangements occur in 2-3% of patients with advanced NSCLC.
