Bcl-2 Inhibitor GDC-0199 in Combination With Obinutuzumab and Ibrutinib in Treating Patients With Relapsed, Refractory, or Previously Untreated Chronic Lymphocytic Leukemia

Summary

This phase Ib/II trial studies the best dose and safety of Bcl-2 inhibitor GDC-0199 in combination with obinutuzumab and ibrutinib and to see how well they work in treating patients with chronic lymphocytic leukemia that has returned (relapsed), does not respond to treatment (refractory), or is previously untreated. Bcl-2 inhibitor GDC-0199 and ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as obinutuzumab, may block cancer growth in different ways by targeting certain cells. Giving Bcl-2 inhibitor GDC-0199 together with obinutuzumab and ibrutinib may be a better treatment for chronic lymphocytic leukemia.
