Official title

Intermittent Therapy With the BTK Inhibitor Acalabrutinib (Calquence) in Combination With Obinutuzumab in Treatment Naive (Tn) Patients With Chronic Lymphocytic Leukemia (CLL)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This phase II trial investigates the how well acalabrutinib and obinutuzumab work in treating patients with chronic lymphocytic leukemia (CLL). Acalabrutinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with obinutuzumab may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Giving acalabrutinib and obinutuzumab may help to control disease progression in CLL patients who have not received treatment for CLL.
