About this study

Official title: A Phase II Study of MOR00208 in Combination With Lenalidomide for Patients With Relapsed or Refractory Chronic Lymphocytic Leukemia(CLL)/Small Lymphocytic Lymphoma (SLL)/Prolymphocytic Leukemia (PLL), Including Those Who Have Relapsed on Ibrutinib, or Patients With Untreated CLL/SLL/PLL and an Open Pilot Study for Patients With Richters Transformation (RT)

This phase II trial studies how well anti-cluster of differentiation (CD)19 monoclonal antibody MOR00208 and lenalidomide work in treating patients with relapsed, refractory, or previously untreated chronic lymphocytic leukemia, small lymphocytic lymphoma, or prolymphocytic leukemia. Monoclonal antibodies, such as anti-CD19 monoclonal antibody MOR00208, can block cancer growth in different ways. Some block the ability of cancer to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Biological therapies, such as lenalidomide, may stimulate the immune system in different ways and stop cancer cells from growing. Giving anti-CD19 monoclonal antibody MOR00208 and lenalidomide may kill more cancer cells.

PRIMARY OBJECTIVES:

  1. To determine the overall response rate (ORR) at 6 months for patients with relapsed or refractory chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL)/prolymphocytic leukemia (PLL) treated with the combination of MOR00208 plus lenalidomide.

II. To determine the overall response rate (ORR) at 6 months for patients with treatment-naive CLL/SLL/PLL treated with the combination of MOR00208 plus lenalidomide.

III.To obtain preliminary data on toxicity profiles and efficacy with the combination of MOR00208 plus lenalidomide in patients with Richter's Transformation IV. To obtain preliminary data on efficacy of MOR00208 in patients with progressive disease on ibrutinib monotherapy

SECONDARY OBJECTIVES:

  1. To determine the overall response rate (ORR) at 12 months for patients with untreated CLL/SLL/PLL or relapsed/refractory disease treated with the combination of MOR00208 plus lenalidomide.

II. To determine the complete response (CR) rate, nodular partial response (nPR) rate, partial response (PR) rate, and stable disease (SD) rate for patients with untreated CLL/SLL/PLL or relapsed or refractory disease treated with the combination of MOR00208 plus lenalidomide.

III. To summarize the progression free survival (PFS), time to next treatment, and overall survival (OS) for each of two cohorts of patients treated with this regimen.

IV. To evaluate toxicity with this regimen, including frequency and severity of toxicities, dose reduction requirements, and adverse events requiring drug discontinuation.

  1. To perform baseline analysis of patients enrolled on this trial including fluorescence in situ hybridization (FISH), stimulated karyotype, zeta-chain-associated protein kinase 70 (Zap-70) methylation, and immunoglobulin variable region heavy chain (IgVH) mutational status and describe relationships between these biomarkers and ORR or PFS for each of two cohorts with this regimen.

VI. To determine the effect of this regimen on total immunoglobulins, CD4+ and CD8+ T cells, natural killer (NK) cells, and interleukin-21 receptor (IL-21R) expression on CLL cells.

VII. To determine whether NK cells and T cells are activated in response to MOR00208 alone or in combination with lenalidomide.

VIII. To estimate the rate of minimal residual disease (MRD) in patients achieving CR, and whether this correlates with PFS.

What is being measured

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

  1. Proportion of patients who achieve a response (i.e. CR, complete response with incomplete recovery [CRi], nPR, or PR), as defined according to the IWCLL 2008 criteria

    Within each cohort, the proportion of patients who achieve an overall response will be estimated by the sum of the number of complete responses, complete responses with incomplete recovery, nodular partial responses, and partial responses divided by the total number of evaluable patients. Ninety percent exact binomial confidence intervals for the true overall response rate will be calculated for those patients included to evaluate the decision criteria.

    Measured: up to 6 months

Secondary outcomes (15)

  1. ORR

    The ORR with 90% exact binomial confidence intervals will be calculated. The degree of response for evaluable patients will also be summarized. In addition, the number of patients who achieve CR but remain positive for MRD will be documented.

    Measured: At 12 months

  2. PFS

    PFS will be summarized with simple descriptive statistics obtained using the Kaplan-Meier method.

    Measured: From the date of registration to date of relapse or death, assessed up to 12 months

  3. Time to next treatment

    Time to next treatment will be summarized with simple descriptive statistics obtained using the Kaplan-Meier method.

    Measured: From date of registration until date of next treatment or death, censoring those alive who have not started another treatment at last follow-up, assessed up to 12 months

  4. OS

    OS will be summarized with simple descriptive statistics obtained using the Kaplan-Meier method.

    Measured: From date of registration until date of death or last follow-up, assessed up to 12 months

  5. Results of FISH

    Relationships between FISH variables and ORR or PFS will be explored graphically (e.g. side-by-side boxplots or Kaplan-Meier plots), where estimates with confidence intervals will be presented as the primary method of analysis due to the limited number of patients.

    Measured: Baseline

  6. Results of stimulated karyotype

    Relationships between stimulated karyotype variables and ORR or PFS will be explored graphically (e.g. side-by-side boxplots or Kaplan-Meier plots), where estimates with confidence intervals will be presented as the primary method of analysis due to the limited number of patients.

    Measured: Baseline

  7. Zap-70 methylation

    Relationships between Zap-70 variables and ORR or PFS will be explored graphically (e.g. side-by-side boxplots or Kaplan-Meier plots), where estimates with confidence intervals will be presented as the primary method of analysis due to the limited number of patients.

    Measured: Baseline

  8. IgVH mutational status

    Relationships between IgVH variables and ORR or PFS will be explored graphically (e.g. side-by-side boxplots or Kaplan-Meier plots), where estimates with confidence intervals will be presented as the primary method of analysis due to the limited number of patients.

    Measured: Baseline

  9. Effects of combined therapy with MOR00208 and lenalidomide on CD4+ T cells using flow cytometry during the course of protocol therapy

    Patterns will be explored graphically using box plots and/or individual time plots as well as analytically with either repeated measures analysis of variance or Friedman's nonparametric test, recognizing the inherent limitations due to sample size.

    Measured: Up to 12 months

  12. Changes in IL-21R expression

    Measured: Baseline to up to 12 months

  13. Changes in expression of select genes associated with B-cell activation

    Measured: Baseline up to 12 months

  14. Incidence of adverse events as graded per the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0

    The maximum grade for each type of toxicity will be recorded for each patient, and frequency tables will be reviewed for each cohort to determine toxicity patterns. The incidence of severe (grade 3+) adverse events or toxicities will be described.

    Measured: Up to 12 months

  15. Tolerability assessed by the number of patients who require dose modifications and/or dose delays

    Measured: Up to 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing MOR00208, lenalidomide and Correlative Studies in people with Contiguous Stage II Small Lymphocytic Lymphoma and Noncontiguous Stage II Small Lymphocytic Lymphoma, run by Ohio State University Comprehensive Cancer Center 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 26 inclusion and 14 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 Dec 2025. 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?

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?

Proportion of patients who achieve a response (i.e. CR, complete response with incomplete recovery [CRi], nPR, or PR), as defined according to the IWCLL 2008 criteria (time frame: up to 6 months). 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 NCT02005289.

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 Dec 2025.
