Summary

This completed study looked at the safety of the drug Calquence (acalabrutinib) in 104 patients with relapsed or refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma. Researchers tracked side effects like bleeding, infections, and heart issues in a real-world setting after the drug was already on the market. The goal was to better understand how often these side effects occur outside of controlled clinical trials.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Calquence (acalabrutinib)
What this could lead to
If successful, this study could confirm that Calquence is safe enough for routine use in patients with relapsed or refractory CLL.
What could go wrong
This is an observational study, not a controlled trial, so it cannot prove effectiveness. Side effects like bleeding, infection, and heart issues were tracked and may still occur.
