NCT ID NCT04963946

First seen Dec 08, 2025 · Last updated May 16, 2026 · Updated 25 times

Summary

This study looks at whether older, frail patients with untreated chronic lymphocytic leukemia (CLL) can safely stop taking the targeted drug acalabrutinib after 18 months and then restart it only if their disease comes back. The goal is to reduce long-term side effects and lower the chance of drug resistance. About 160 patients aged 70 and older will take part.
