Zai Lab Announces NDA for Omadacycline Granted Priority Review by China's NMPA

SHANGHAI, China, and SAN FRANCISCO, May 06, 2020 (GLOBE NEWSWIRE) -- Zai Lab Limited ZLAB, an innovative commercial stage biopharmaceutical company, today announced that the Center for Drug Evaluation of China's National Medical Products Administration (NMPA) has granted priority review status to the New Drug Application (NDA) for omadacycline for the treatment of community-acquired bacterial pneumonia (CABP) and acute bacterial skin and skin structure infections (ABSSSI).

"The NMPA's decision to grant priority review to our NDA for omadacycline underscores the importance of addressing a growing unmet need of bacterial resistance in China with an innovative medicine," said Dr. Samantha Du, Founder, Chairperson and Chief Executive Officer of Zai Lab. "We believe omadacycline is particularly well positioned for the China market due to its broad activity covering a wide spectrum of pathogens, including multi-drug resistant bacteria, associated with CABP and ABSSSI. We look forward to working closely with the agency to move our first anti-infective therapeutic toward approval."

"CABP is a common secondary infection associated with respiratory viruses like influenza and coronavirus, and recent influenza outbreaks and coronavirus epidemics are a reminder of the need for antibiotics like omadacycline. We believe few intravenous/oral antibiotics exist which are as potent as omadacycline in this indication," added Dr. Harald Reinhart, Chief Medical Officer for Autoimmune and Infectious Diseases of Zai Lab.

Priority review was established in China to facilitate drug registration and accelerate the development of new drugs with clinical value under the guidance of Opinions on Encouraging Pharmaceutical Innovation via Priority Review & Approval issued by the NMPA in December 2017. According to these guidelines, the NMPA will prioritize the review of and evaluation resources for applications under priority review, which are expected to result in reduced review and approval timelines.
