About this study
Official title: Daratumumab and Ibrutinib for Symptomatic, Treatment-Naive CLL: A Phase 1b Proof-of-Concept Study
This phase Ib trials studies the side effects of daratumumab and ibrutinib and how well they work in treating patients with symptomatic chronic lymphocytic leukemia. Monoclonal antibodies, such as daratumumab, may interfere with the ability of cancer cells to grow and spread. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving daratumumab and ibrutinib may work better in treating patients with chronic lymphocytic leukemia.
Read the detailed description
PRIMARY OBJECTIVES:
- To characterize the safety of treatment with daratumumab and ibrutinib for previously untreated chronic lymphocytic leukemia (CLL).
II. To determine the complete response rate (CR) at the post cycle 12 response assessment following treatment with daratumumab and ibrutinib for previously untreated chronic lymphocytic leukemia (CLL).
SECONDARY OBJECTIVES:
- To characterize the activity of daratumumab and ibrutinib as measured by overall response rate (ORR), duration of response (DOR), progression-free survival (PFS), overall survival (OS), and time-to-next treatment.
TERTIARY OBJECTIVES:
- To measure pharmacodynamic parameters in B cells including drug occupancy of BTK and B cell receptor signaling during treatment.
II. To determine the influence of this combination on T cell and natural killer (NK) cell number and function.
III. To assess for development of mutations that may confer resistance to this combination.
IV. To assess the ability of daratumumab to clear CLL in the peripheral blood and association of CD38 expression on CLL cells with response.
OUTLINE:
Patients receive daratumumab intravenously (IV) on days 1, 8, 15, and 22 of courses 1-2, days 1 and 15 of courses 3-6, and day 1 of subsequent courses. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity. Beginning course 2, patients also receive ibrutinib orally (PO) once daily (QD) on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 12 weeks for up to 2 years.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Daratumumab, Ibrutinib and Laboratory Biomarker Analysis in people with Chronic Lymphocytic Leukemia, run by Jennifer Woyach at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 27 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Complete response (CR) + complete response with incomplete marrow recovery (CRi) defined by the International Workshop on Chronic Lymphocytic Leukemia (IWCLL) 2008 criteria (time frame: Up to 2 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Jun 2026.
