ASSURE Trial Summary

This trial is testing a new medication, acalabrutinib, to see if it is safe and effective in treating people with chronic lymphocytic leukemia. The trial will last for approximately 72 months and will enroll 600 participants.

Who is the study for?
This trial is for adults with chronic lymphocytic leukemia (CLL) who are either untreated, have relapsed or are refractory to previous treatments, or have had prior ibrutinib therapy. Participants must show signs of progressive disease and meet specific blood cell count criteria. Pregnant women, individuals with recent malignancies other than CLL, those on certain medications like proton-pump inhibitors or strong CYP3A inhibitors/inducers, and patients with significant heart issues cannot join.Check my eligibility
What is being tested?
The study tests the safety and effectiveness of acalabrutinib taken twice daily in three groups: treatment-naive patients, those whose CLL has returned or didn't respond to past treatments, and patients previously treated with ibrutinib. The trial will last about six years including a two-year recruitment phase followed by up to four years of treatment cycles.See study design
What are the potential side effects?
Potential side effects from acalabrutinib may include headache, diarrhea, muscle pain, feverish symptoms similar to colds or flu-like conditions. There could also be more serious risks such as bleeding problems due to low platelet counts or high blood pressure.

Experimental Treatment
Group I: AcalabrutinibExperimental Treatment1 Intervention
Participants will be enrolled into 3 cohorts. In the treatment-naive cohort, a minimum of 300 participants with treatment-naïve chronic lymphocytic leukemia will be enrolled. In the relapsed/refractory cohort, approximately 200 participants with relapsed/refractory chronic lymphocytic leukemia will be enrolled. In the prior ibrutinib cohort, approximately 40 participants with Prior ibrutinib therapy will be enrolled.
