About this study

Official title: A Phase II Trial of Revlimid® and Rituximab, for the Treatment of Patients With Relapsed or Refractory Chronic Lymphocytic Leukemia (CLL)

The Chronic Lymphocytic Leukemia (CLL) Research Consortium (CRC) is conducting a two-arm, multi-center phase II trial of Revlimid® and rituximab for Relapsed or Refractory CLL for patients under the age of 65 and patients 65 years and older.

Lenalidomide (Revlimid) is an immunomodulatory agent with promising clinical activity in CLL and is FDA approved for treatment of relapsed multiple myeloma and 5q-myelodysplastic syndrome. Rituximab (Rituxan) is a monoclonal antibody to CD20 that is approved for the treatment of CLL.

The primary objective of this study is to determine the overall response rate of the combination of Revlimid® and rituximab in previously treated CLL patients. All patients will receive treatment with Revlimid® starting at a low dose that will be dose escalated based on individual patient tolerability. The combination of Revlimid and Rituximab will be administered for a maximum of 7 cycles. Patients with residual leukemia following seven cycles of treatment with the combination may elect to continue on protocol for an additional 6 cycles of single agent Revlimid® consolidation.

Read the detailed description

The Chronic Lymphocytic Leukemia (CLL) Research Consortium (CRC) is conducting a two-arm, multicenter phase II trial of Revlimid® and rituximab for Relapsed or Refractory Chronic Lymphocytic Leukemia (CLL) for patients under the age of 65 and patients 65 years and older.

Revlimid® (lenalidomide) a derivative of thalidomide with immune-modulating properties. Revlimid® is FDA approved for treatment of relapsed multiple myeloma and 5q- myelodysplastic syndrome. Revlimid® has promising clinical activity, in both previously treated and treatment naive CLL in early clinical trials. However, the mechanism(s) whereby Revlimid® is active in CLL is unknown. Rituximab (Rituxan®) is a monoclonal antibody that binds to CD20 expressed on normal and leukemia B cells. Rituximab is approved for the treatment of CLL.

In preclinical models of lymphoma Revlimid improved the activity of Rituximab. In clinical studies of relapsed and/or refractory CLL the combination Revlimid and Rituximab was associated with better therapeutic effects compared with what was historically observed with either agent alone.

The purpose of this study is to evaluate the safety and activity of the combination of Revlimid® and rituximab in relapsed or refractory CLL, elucidate the mechanism of action of Revlimid® in CLL, and to assess whether prognostic factors might predict those patients likely to benefit from this therapy in the future.

The primary objective of this study is to determine the overall response rate (ORR) of the combination of Revlimid® and rituximab in previously treated CLL patients for those age 65 years and above and those younger than 65.

Secondary objectives will evaluate the safety of the combination of Revlimid® and Rituximab, response duration, improvement in hematologic parameters, activity of the combination in high-risk CLL subsets, the significance of the tumor flare reaction and to compare the activity of this regimen when administered to previously treated patients to our protocol in the front line setting and to compare these outcomes for both arms of the study.

All patients will receive treatment with Revlimid® starting at a low dose that will be slowly dose escalated based on individual patient tolerability. The combination of Revlimid and Rituximab will be administered for a maximum of 7 cycles. Patients with residual leukemia following seven cycles of treatment with the combination may elect to continue on protocol for an additional 6 cycles of single agent Revlimid® consolidation.

All patients will have baseline assessment of known CLL prognostic factors through the CRC tissue core. These known prognostic features in CLL together with novel prognostic factors will be evaluated for the ability to predict response to treatment with Revlimid® and the combination of Revlimid® and Rituximab.

Study groupRoleWhat they receive
Revlimid + RituximabExperimentalA: Lenalidomide starting at a low dose 2.5 or 5 mg, 21 days/cycle escalated based on patient tolerability. Rituximab at 375mg/m2 administered following the first 21 days of lenalidomide monotherapy, continued weekly throughout cycle 2, and then every 4 weeks for subsequent cycles (3-7). Each patient may receive up to 7 cycles of treatment with the combination lenalidomide/rituximab if no progressive disease or significant toxicity. Patients with residual disease can elect to receive 6 additional cycles of single agent Revlimid as consolidation. Each patient may receive up to a maximum of 13 cycles of treatment if no progressive disease or significant toxicity.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Revlimid and Rituximab in people with Chronic Lymphocytic Leukemia and CLL, run by University of California, San Diego 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 10 inclusion and 15 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 Aug 2024. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 23 Oct 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Overall Response Rate (ORR) (time frame: nine months). 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 Aug 2024.
