A Phase 2 Single Arm Study to Investigate the Safety and Clinical Activity of Idelalisib Alone and in Combination With Rituximab in Elderly Subjects With Previously Untreated Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma

The purpose of this study is to see if an investigational drug named CAL-101, when given in combination with rituximab (also known as Rituxan), is safe to give to people with previously untreated Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma. "Investigational" means that this study drug is being tested in people and has not been approved by the United States Food and Drug Administration (FDA).
