Zai Lab (NASDAQ: ZLAB, HKG: 9688) announced Q4 and full‑year 2025 financial results, with net product revenue reaching USD 457.2 million (up 16% YoY). The growth was primarily driven by increased sales volumes of Xacduro (durlobactam/sulbactam) and Nuzyra (omadacycline), alongside steady performance from the PARP inhibitor franchise.
Oncology Leadership:DLL3 ADC (zoci) advances to pivotal studies across small cell lung cancer (SCLC) and neuroendocrine carcinomas, positioning Zai Lab in high‑unmet‑need tumor types.
Immunology Expansion:IL‑13/IL‑31 bispecific targets atopic dermatitis and pruritus; FIH data will inform differentiation vs. existing IL‑13/IL‑31 programs.
Novel Modalities: Investment in T‑cell engagers and immunocytokines beyond IL‑12 diversifies pipeline beyond traditional antibodies and ADCs.
China Commercial Execution: Zejula maintains PARP inhibitor leadership despite competitive pressure; Xacduro and Nuzyra demonstrate launch execution capabilities.
