Official title
Zanubrutinib and Venetoclax as Initial Therapy for CLL With Obinutuzumab Consolidation in Patients With Minimal Residual Disease Positivity (BruVenG)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Bruton's tyrosine kinase inhibitors (BTKi), anti-CD20 antibodies, and the B cell lymphoma 2 inhibitor (BCL-2i) venetoclax are drug classes used to treat patients with chronic lymphocytic leukemia/small lymphocytic leukemia (CLL/SLL). Anti-CD20 therapy may not be required for all patients. The investigators hypothesis is that it may be better to give anti-CD20 therapy (obinutuzumab) only to patients that still have detectable cancer in their blood (minimal residual disease \[MRD\]) after being treated with a combination of two oral medications, zanubrutinib (a BTKi ) and venetoclax (a BCL-2i), instead of giving a combination of three drugs to all patients from the start of treatment. This strategy, if effective, will prevent overtreatment with anti-CD20 antibodies; reduce side effects of treatment while potentially increasing MRD negativity rates; and will possibly make the anti-CD20 antibody therapy more effective given the low tumor burden present when utilized. This study will test this hypothesis by treating subjects with 3 cycles of a zanubrutinib monotherapy lead-in, in order to debulk and mitigate tumor lysis risk, followed by 13 cycles of zanubrutinib and venetoclax combination therapy. Subjects who are both peripheral blood and bone marrow MRD negative at the completion of the 13 cycles of combination therapy will stop treatment and enter an observation phase every 3 months. Subjects that are MRD positive will continue combination therapy with zanubrutinib and venetoclax for an additional 6 cycles but also receive 6 cycles of obinutuzumab in order to augment response and increase MRD negative rates for the overall treated cohort.
