Summary

This study tests whether giving a second course of venetoclax plus obinutuzumab can control chronic lymphocytic leukemia (CLL) when it comes back after initial treatment. About 75 adults whose CLL returned after prior successful therapy will receive the drug combination for up to 24 cycles. Researchers will monitor tumor shrinkage, side effects, and overall response to see if retreatment is effective and safe.
