摘要: Purpose: WX-G250 is a chimeric monoclonal antibody that binds to carbonic anhydrase IXG250/MN, which present on greater than 95% of RCCs the clear cell subtype. The suggested working mechanism by ADCC. Because number activated ADCC effector cells can be increased low dose interleukin-2 pulsing schedule, multicenter study was initiated investigate whether combined with LD-IL-2 could lead an improved clinical outcome in patients progressive RCC.Materials and Methods: A total 35 RCC received weekly infusions for 11 weeks daily regimen. Patients were monitored longitudinally capacity. Radiological assessment metastatic lesions performed at week 16 regularly until disease progression.Results: durable benefit achieved 8 (23%), including 3 partial response 5 stabilization 24 or greater. Mean survival 22 mo...
