Chronic Lymphocytic Leukemia study: NX-5948

Official title A Study of NX-5948 in Adults With CLL/SLL Previously Treated With a Bruton's Tyrosine Kinase Inhibitor and a B-cell Lymphoma-2 Inhibitor (DAYBreak CLL-201)

ClinicalTrials.gov ID: NCT07221500

What this study is testing

What is NX-5948?

An investigational oral medicine being studied for relapsed or refractory chronic lymphocytic leukemia or small lymphocytic lymphoma. It is designed to degrade the BTK protein, thereby disrupting its activity.

Also referred to as Bexobrutideg.

Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
The study aims to see if NX‑5948 can help treat chronic lymphocytic leukemia or small lymphocytic lymphoma that has not responded to earlier treatments.
Who it's for
Adults with relapsed or refractory CLL or SLL who have previously received both a BTK inhibitor and a BCL‑2 inhibitor.
What's involved
Participants will receive the drug and have regular clinic visits and medical tests to monitor safety and effectiveness.
Time commitment
The study could last up to 5 years, with ongoing visits as needed if the disease does not progress.
