In this study, we report the Asian experience with brentuximab vedotin in patients with relapsed or refractory CD30-positive (CD30+) HL. Methods: This is an observational, multicenter, retrospective study. Between October 2011 and June 2013, a total of 22 patients were treated with brentuximab vedotin under a named patient program in Asia. Patients received a 30 min infusion of brentuximab vedotin at a dose of 1.8 mg/kg of body weight every 3 weeks. Results: Four patients (18.2%) showed a complete response, and the overall response rate was 72.7%. The median duration of response was 4.4 months (range 1.0–17.4). The median progression-free survival was 5.7 months, and the median overall survival has not yet been reached. The 1-year expected survival rate was 67.2%. The most common grade 3/4 adverse events were neutropenia (n=7; 31.8%). No patients experienced grade 3/4 sensory neuropathy. Conclusions: These results confirm that brentuximab vedotin as a single agent is also effective and well tolerated when used in Asian patients with relapsed and refractory CD30+ HL.
