NCT ID NCT03534323

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests a combination of two drugs, duvelisib and venetoclax, in 55 people with relapsed or refractory chronic lymphocytic leukemia (CLL) or Richter's syndrome. Duvelisib blocks a protein that helps cancer cells survive, while venetoclax targets another survival protein. The goal is to see how many patients achieve complete remission. The trial is active but no longer recruiting.
