SHANGHAI and CAMBRIDGE, Mass., Jan. 30, 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 status to the New Drug Application (NDA) for sulbactam-durlobactam (SUL-DUR) for the treatment of infections caused by Acinetobacter baumannii, including multidrug-resistant and carbapenem-resistant (CRAB) strains.
“The CDE’s decision to grant priority review to our NDA for SUL-DUR underscores the importance of addressing the urgent need for new treatment options for patients with life-threatening infections caused by Acinetobacter species including multidrug and carbapenem-resistant strains,” said Harald Reinhart, M.D., President and Head of Global Development, Neuroscience, Autoimmune and Infectious Diseases, Zai Lab. “CRAB infections are among the worst bacterial infections, and safe and effective treatment options are limited. We thank the agency for their commitment and continued support to patients in need and look forward to working closely with them to advance this important therapy toward approval in China, where CRAB infections are still frequently seen in ICUs and result in high mortality rates.”
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 Rules (Bureau Order 27) and the Working Procedure for Priority Review and Approval of Drug Marketing Authorization (Tentative, NMPA 2020 No. 82) effective on July 1, 2020 and July 7, 2020, respectively. According to these guidelines, the regulatory authority will prioritize the evaluation resources for applications under priority review to help reduce review and approval timelines.

About Acinetobacter baumannii Infections in China
Based on the 2020 Annual Report of CARSS (China Antimicrobial Resistance Surveillance System), there were around 220,000 Acinetobacter infections reported in 2020 in China, although the actual incidence is estimated to be much larger. The resistance of Acinetobacter baumannii to the carbapenem class of antibiotics was estimated at 54% in 2020 across China, with some provinces as high as 70-80%. Acinetobacter is also the most common pathogen that leads to hospital-acquired pneumonia and ventilator-acquired pneumonia in China1. With best available therapy, the mortality rate is estimated to be 50% in China2.
