Clinical Progress: zocilurtatug pelitecan (zoci)
Zai Lab’s flagship product, the antibody‑drug conjugate zocilurtatug pelitecan (zoci), has entered Phase 1b development for extensive‑stage small‑cell lung cancer. In a recent study, the combination of zoci with the immune checkpoint inhibitor atezolizumab produced a high response rate, encouraging durability, and a safety profile that diverges from traditional platinum‑based regimens. These findings have generated optimism among investors who view zoci as a potential breakthrough in oncology therapeutics.
Capital Raising and Strategic Outlook
To support global development of zoci and related programs, Zai Lab announced a private placement of American depositary shares that raised approximately US$250 million. The proceeds will be directed primarily toward clinical trials and ancillary development activities. The company is preparing for a forthcoming Phase 3 trial of zoci in first‑line therapy, a critical step that could significantly enhance its product portfolio and market positioning.

Among these, Yes Optoelectronics reported a modest revenue increase for Q3 2026, driven by higher sales of core optical products.
