Company Description

Zai Lab (NSDAQ: ZLAB) is an innovative, research-based, commercial stage biopharmaceutical company based in China and the U.S. focused on bringing transformative medicines for cancer, autoimmune and infectious diseases to patients in China and around the world.

Headquartered in Shanghai since our founding in 2014, our experienced team has secured partnerships with leading global biopharma companies, generating a broad and late-stage pipeline of innovative drug candidates. Based on our extensive track record of execution and delivering results, Zai Lab has earned the reputation as a trusted partner of choice for global biopharmaceutical companies seeking to not only access the Chinese market but also find a long-term strategic partner for global clinical development.  Through these partnerships, Zai Lab has built the strongest late stage oncology portfolio with global first-in-class and/or best-in-class profile, among innovative Chinese biotech companies. We are further supplementing our pipeline with an in-house discovery effort aiming to produce 1-2 global INDs per year.

Zai Lab is rapidly expanding into a fully integrated biopharmaceutical company, discovering, developing, manufacturing and commercializing innovative medicines. To that end, we have built our internal R&D center to advance our discovery pipeline, a strong clinical development and operations team, and our own manufacturing facilities in China. We have also established a highly specialized commercial team to support marketing of our innovative products in China. We believe this integrated approach will provide sustainable competitive advantages for Zai Lab.

Zai Lab was successfully listed on the Nasdaq Stock Market in September 2017 and completed secondary listing on Hong Kong Stock Exchange in September 2020. Zai Lab significantly expanded with several offices across China and U.S. and opened its U.S. headquarters in San Francisco in December 2018. As of June 2021, the Company has a global team of over 1600 employees.
