40.9% patients (n = 79) were PD-L1 high-expression, especially in nasopharyngeal cancer (71.8%) and esophageal squamous cell cancer (48.3%) cohorts. Patients with PD-L1 high-expression responded significantly better than those with PD-L1 low-expression (31.1% Versus. 13.7%, p = 0.012). PD-L1 high-expression also contributed to longer median PFS...GLS-010 demonstrated favorable safety and clinical response in refractory population of lymphoma and solid tumors.
