Introduction:
Bruton tyrosine kinase inhibitors (BTKi) are highly effective therapy for chronic lymphocytic leukemia (CLL) but can lead to long-term side effects.
Methods:
We performed a retrospective analysis of venetoclax consolidation of 20 patients with CLL after initial BTKi discontinuation. Patients were administered either single-agent venetoclax or in combination with obinutuzumab.
Results:
The best peripheral blood minimal residual disease (MRD) response was undetectable MRD, occurring in 89% of patients. With a median follow-up of 47.4 months, both the median progression-free survival and time-to-next treatment were not reached.
Conclusion:
Venetoclax consolidation after BTKi is a feasible treatment strategy for patients with CLL, with encouraging efficacy deserving further study. Clinical Trial Registration: N/A.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes.
