-- Company to Host Conference Call and Webcast Today at 8:00 a.m. ET

SHANGHAI and SAN FRANCISCO, March 01, 2021 (GLOBE NEWSWIRE) -- Zai Lab Limited (NASDAQ: ZLAB; HKEX: 9688), an innovative commercial-stage biopharmaceutical company, today reported financial results for the second half and full year of 2020, along with corporate updates.

“2020 was another year of great accomplishment for Zai Lab,” said Dr. Samantha Du, Founder, Chairperson and Chief Executive Officer of Zai Lab. “We successfully launched ZEJULA for both second-line and first-line ovarian cancer and Optune for glioblastoma in China. We submitted NDAs and were granted priority reviews by China’s National Medical Products Administration (NMPA) for both QINLOCK for advanced gastrointestinal stromal tumors (GIST) and NUZYRA for community-acquired bacterial pneumonia (CABP) and acute bacterial skin and skin structure infections (ABSSSI) in China. We continued to expand our pipeline by forming new strategic partnerships with four companies for five compounds that we believe can address significant unmet medical needs. We and our partners continued to execute in clinical development, and we now have 21 product candidates, including 17 in clinical development, 11 in late-stage development and five that have been approved in the United States. Our pipeline of internally developed products with global rights grew to seven, including three in global clinical development.

“Looking ahead to 2021, we expect to receive approval for and launch QINLOCK and NUZYRA in China, bringing our total number of commercial products to four. In addition, ZEJULA for second-line ovarian cancer has been included in the National Reimbursement Drug List (NRDL), and we expect this will drive strong volume growth for the product this year and beyond. We also plan to submit regulatory filings for Tumor Treating Fields in mesothelioma and for MARGENZA in HER2-positive breast cancer in China in 2021. We expect to hold regulatory discussions with the NMPA regarding a potential accelerated regulatory pathway for efgartigimod, which has already been filed by our partner argenx for generalized myasthenia gravis in the United States. And we expect to obtain new clinical data for many products and product candidates.

“We are focused on building disease strongholds in China in three therapeutic areas — oncology, autoimmune disorders and infectious diseases. Within oncology, we have focused on five cancer franchises that account for over half of all new cancer patients in China. These cancer franchises include lung cancer and gastric cancer, where we have a world-class portfolio of product candidates, as well as women’s cancer, brain cancer and hematology. We plan to continue to expand this product pipeline both vertically within these areas of focus and horizontally into new therapeutic areas of significant unmet medical need.

“Over the next three years, our mission is to become a leading global biopharmaceutical company. In addition to seeking to deliver a steady stream of approvals and launches in China from our existing pipeline and forming new strategic collaborations and transformative partnerships, we aim to discover and develop innovative medicines. To accomplish our mission, we will continue to build upon our current scale, which currently consists of nearly 1,200 employees across eight operational locations around the world. While the challenges of COVID-19 continue for all of us, we at Zai Lab remain committed to extending our track record of execution in pursuit of our overall goal of improving human health globally.”
