Study Summary

This trial will study whether it is safe to stop treatment with acalabrutinib and obinutuzumab after the cancer responds to the treatment, followed by a period of observation.

Who is the study for?
This trial is for adults with untreated chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) who need treatment. Participants must be able to follow the study plan, have normal organ function, and if of childbearing potential, agree to use effective contraception. People can't join if they've had prior CLL therapy, bleeding disorders, severe heart conditions, recent major surgery or infections requiring hospitalization within 2 weeks before starting the study.Check my eligibility
What is being tested?
The trial tests whether stopping acalabrutinib and obinutuzumab when cancer responds—followed by a watchful waiting period—is as effective as continuous treatment until disease progression. This approach aims to reduce long-term side effects and prevent resistance to treatment.See study design
What are the potential side effects?
Potential side effects include diarrhea, headache, high blood pressure from acalabrutinib; infusion reactions like fever or chills and low blood cell counts from obinutuzumab. Long-term use may lead to serious complications such as increased infection risk.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Given its side effects, is Acalabrutinib still an effective medication?

"The Power team rates the safety of Acalabrutinib as a 2. This is because it is a phase 2 trial, which means that there is some data supporting its safety, but none indicating whether or not it is effective."
