Immune Profiling of CLL/SLL Treated With First-Line Pirtobrutinib

🩺 Protocol Summary

Background: Chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL) are blood cancers that affect certain white blood cells. Advanced forms of these diseases are difficult to treat. Pirtobrutinib is a drug approved to treat CLL and SLL after 2 previous treatments. Researchers want to know how this drug affects the immune system in those who have not yet started other treatments for CLL or SLL. Objective: To test pirtobrutinib as a first-line treatment for CLL or SLL. Eligibility: People aged 18 years and older with untreated CLL or SLL. Design: Participants will be screened. They will have a physical exam with blood tests. They will have imaging scans and tests of their heart function. They will have a lymph node biopsy: A large needle will be inserted into a lymph node to collect a small piece of tissue. Pirtobrutinib is a tablet taken by mouth. Participants will take 2 to 4 tablets daily in 4-week cycles. Participants will have clinic visits once every 4 weeks for the first 3 months. Then they will be seen once every 3 months. Imaging scans, lymph node biopsy, and other tests will be repeated at various study visits. A bone marrow biopsy (collection of soft tissue from inside a bone) may be done if there is no evidence of disease after 1 year of treatment with the study drug. Participants may opt to have cancer and immune cells collected from their blood. The cells will be used for research. Participants will have a clinic visit 1 month after their last dose of the study drug. Then they will have follow-up visits or phone calls every 6 to 12 months....

💰 Clinical Trial Costs & Insurance Coverage

Coverage for clinical trial participation varies depending on your health insurance policy, state legislation, and whether specific procedures are investigational research or routine medical care. Under federal law (Affordable Care Act § 2709), health insurers generally cannot drop coverage or refuse to pay for routine patient care costs incurred in approved clinical trials.

💡 Always ask the study coordinator for the trial's official Informed Consent Form, which outlines all sponsor-funded research items versus procedures billed to your insurance.
