About this study

Official title: A Phase 1 Study of Lenalidomide and Ibrutinib in Combination With Rituximab in Relapsed and Refractory CLL and SLL

This phase I trial studies the side effects and best dose of lenalidomide when given together with ibrutinib and rituximab in treating patients with chronic lymphocytic leukemia or small lymphocytic lymphoma that has come back (relapsed), has not responded well to prior treatments (refractory), has spread to other parts of the body (metastatic), or cannot be removed by surgery. Biological therapies, such as lenalidomide, use substances made from living organisms that may stimulate or suppress the immune system in different ways and stop cancer cells from growing. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Rituximab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Giving lenalidomide together with ibrutinib and rituximab may kill more cancer cells.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To determine the recommended phase II doses of lenalidomide and ibrutinib for combination with rituximab in previously treated chronic lymphocytic leukemia and small lymphocytic lymphoma.

SECONDARY OBJECTIVES:

  1. To determine the safety and tolerability of the combination of lenalidomide, ibrutinib and rituximab in previously treated chronic lymphocytic leukemia and small lymphocytic lymphoma.

II. To describe any preliminary evidence of antitumor activity of the combination of lenalidomide, rituximab and ibrutinib in previously treated chronic lymphocytic leukemia and small lymphocytic lymphoma as defined by response rate, duration of response, and progression-free survival.

III. To observe and record anti-tumor activity.

OUTLINE: This is a dose-escalation study of lenalidomide.

Patients receive rituximab intravenously (IV) on day 1 (up to 6 cycles), lenalidomide orally (PO) once daily (QD) on days 1-21 (up to 12 cycles), and ibrutinib PO QD on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Patients undergo electrocardiogram (ECG) on screening and computed tomography (CT) scan or magnetic resonance imaging (MRI), bone marrow biopsy and blood sample collection throughout the study.

After completion of study treatment, patients are followed up at 30 days and every 6 months for 10 years.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Recommended phase II dose of lenalidomide and ibrutinib with rituximab based on the maximum tolerated dose and the assessment of any clinically relevant toxicity

    Graded according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0.

    Measured: Up to 28 days

Secondary outcomes (5)

  1. Incidence of adverse events

    Graded according to NCI CTCAE version 4.0. Descriptive statistics will be used in the analysis of all laboratory and safety parameters (adverse events, serious adverse events, adverse events leading to discontinuation, deaths) for all treated patients.

    Measured: Up to 30 days following the last dose of ibrutinib

  2. Overall response rate

    The proportion of patients who achieve stable disease (SD) or a partial response (PR) or complete response (CR) will be reported with a 95% exact binomial confidence interval.

    Measured: From the start of the treatment until disease progression/recurrence or death, assessed up to 10 years

  3. Complete response rates

    The proportion of patients who achieve CR will be reported with a 95% exact binomial confidence interval.

    Measured: Up to 10 years

  4. Duration of response

    Measured: From the time measurement criteria are met for CR or PR (whichever is first recorded) until the first date that recurrent or progressive disease is objectively documented or death, assessed up to 10 years

  5. Progression-free survival

    The progression-free survival will be evaluated using the methods of Kaplan and Meier.

    Measured: Time from start of treatment to time of progression or relapse or death, whichever occurs first, assessed up to 10 years

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Biospecimen Collection, Bone Marrow Biopsy and Computed Tomography in people with Recurrent Chronic Lymphocytic Leukemia and Recurrent Small Lymphocytic Lymphoma, run by National Cancer Institute (NCI) at 2 sites 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 51 inclusion and 28 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: under way, not looking for participants, as of the sponsor's last update on 21 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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?

This study is still under way. Results are not available in the source record yet.

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?

Recommended phase II dose of lenalidomide and ibrutinib with rituximab based on the maximum tolerated dose and the assessment of any clinically relevant toxicity (time frame: Up to 28 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02160015.

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 21 Aug 2026.
