NCT ID NCT02846623

First seen Feb 17, 2026 · Last updated May 12, 2026 · Updated 9 times

Summary

This study tests a combination of three drugs—atezolizumab, obinutuzumab, and venetoclax—in about 50 adults with chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma, or Richter syndrome that has returned or not responded to prior treatment. The goal is to see if the combination can make the cancer undetectable in the bone marrow (called MRD-negative). Participants receive the drugs intravenously and orally over several months, and researchers monitor side effects and treatment response.
