• In January 2020, Zai Lab launched ZEJULA in China.
• In December 2019, Zai Lab announced that the China NMPA approved the NDA for ZEJULA as maintenance treatment of patients with recurrent ovarian cancer. This approval represents the fastest approval time by the NMPA in 2019 for a   locally manufactured, category 1 oncology drug.

• Continue to collaborate with our Partner GSK on additional indications and opportunities

Tumor Treating Fields

Tumor Treating Fields is a cancer therapy that uses electric fields tuned to specific frequencies to disrupt cell division, inhibiting tumor growth and potentially causing cancer cells to die.
