An Expanded Access, Open-Label Study of Obinutuzumab (GA101) Plus Chlorambucil in Patients With Previously Untreated Chronic Lymphocytic Leukemia

This is a multicenter, open-label, single-arm, expanded access treatment study designed to provide obinutuzumab to patients with previously untreated Chronic Lymphocytic Leukemia (CLL) in combination with chlorambucil and to evaluate the safety and efficacy of obinutuzumab administered in combination with chlorambucil. This study will enroll patients with previously untreated CD20-positive CLL requiring treatment according to the IWCLL guidelines (Hallek et al 2008), as assessed by the investigator.
