Study Summary

This trial is testing a new anti-cancer drug (venetoclax) to see if it can help treat patients with chronic lymphocytic leukemia who have not received previous treatment. The drug is being added to the usual treatment of ibrutinib and obinutuzumab. The trial will also investigate whether patients who receive all three treatments and have no detectable chronic lymphocytic leukemia after one year of treatment, can stop taking ibrutinib.

Eligible Conditions
  • Chronic Lymphocytic Leukemia
  • Small Lymphocytic Lymphoma

Eligibility Criteria

Age 65+ · All Participants · 10 Total Inclusion Criteria

Mark “Yes” if the following statements are true for you:
Patients must be intermediate or high-risk Rai stage CLL or SLL.
You have neoplastic cells on immunophenotype (performed locally) that express the B cell surface markers of CD19 and CD20, as well as the T cell antigen CD5.
You have been diagnosed with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) with < 5000 B-cells per uL of blood but with disease-associated lymphadenopathy.
This blood submission is mandatory prior to registration/randomization to perform fluorescence in situ hybridization (FISH) centrally that will be used for stratification
You have ≥ 5 x10^9 B lymphocytes (5000/uL) in the peripheral blood measured by flow cytometry at any point in the course of the disease or less peripheral blood involvement but disease-associated lymphadenopathy.
