Pembrolizumab Alone or With Idelalisib or Ibrutinib in Treating Patients With Relapsed or Refractory Chronic Lymphocytic Leukemia or Other Low-Grade B-Cell Non-Hodgkin Lymphomas

NCT02332980

Description:

This phase II trial studies how well pembrolizumab alone or with idelalisib or ibrutinib works in treating patients with chronic lymphocytic leukemia or other low-grade B-cell non-Hodgkin lymphomas that have returned after a period of improvement or have not responded to treatment. Monoclonal antibodies, such as pembrolizumab, block cancer growth in different ways by targeting certain cells and allow the immune system to attack the cancer. Idelalisib and ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving pembrolizumab alone or with idelalisib or ibrutinib may be an effective treatment in patients with chronic lymphocytic leukemia or other low-grade B-cell non-Hodgkin lymphomas.

Detailed Description

      PRIMARY OBJECTIVES:

      I. Test the efficacy (overall response rate) of single-agent MK-3475 (pembrolizumab) in
      relapsed chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) (Arm A) other
      low grade B-cell non-Hodgkin lymphoma (B-NHL), and CLL with Richter's transformation (Arm C).

      SECONDARY OBJECTIVES:

      I. Test the safety of single-agent MK-3475 in relapsed CLL/SLL (Arm A), other low grade B-NHL
      (Arm B), and CLL with Richter's transformation (Arm C).

      II. Test the progression free survival, treatment free survival, duration of response and
      time to next therapy of single-agent MK-3475 in relapsed CLL/SLL (Arm A), other low grade
      B-NHL (Arm B), and CLL with Richter's transformation (Arm C).

      III. Test the complete response rate of single MK-3475 in relapsed CLL/SLL (Arm A), other low
      grade B-NHL (Arm B), and CLL with Richter's transformation (Arm C).

      IV. Test the safety of MK-3475 in combination with the signal inhibitor (either idelalisib or
      ibrutinib) in relapsed CLL/SLL (Arm A) and CLL with Richter's transformation (Arm C).

      V. Test the progression-free survival, treatment-free survival, duration of response and time
      to next therapy of MK-3475 in combination with the signal inhibitor (either idelalisib or
      ibrutinib) in relapsed CLL/SLL (Arm A) and CLL with Richter's transformation (Arm C).

      VI. Test the overall and complete response rates of MK-3475 in combination with the signal
      inhibitor (either idelalisib or ibrutinib) in relapsed CLL/SLL (Arm A) and CLL with Richter's
      transformation (Arm C).

      TERTIARY OBJECTIVES:

      I. To assess the potential association between programmed cell death ligand 1
      (PD-L1)/programmed cell death 1 (PD-1)/PD-L2 expression on tumor and T cells and/or PD-L1
      soluble levels in plasma with clinical efficacy of PD-1 blockade.

      II. To investigate the effects of MK-3475 on selected markers of immune modulation and immune
      profiles in peripheral blood and tumor samples.

      III. Examine T-cell immune synapse function and expression/location of co-stimulatory and
      co-inhibitory molecules (including effector molecules) as potential biomarkers to response
      for anti-PD-1 immune checkpoint blockade immunotherapy.

      OUTLINE:

      ALL PATIENTS (ARMS A, B, and C): Patients receive pembrolizumab intravenously (IV) over 30
      minutes on day 1. Treatment repeats every 21 days for up to 12 months in the absence of
      disease progression or unacceptable toxicity. Patients receiving benefit may continue to
      receive treatment for an additional 12 months at the discretion of the investigator. Patients
      with CLL or CLL with Richter's transformation experiencing stable disease without partial
      remission or progressive disease at 3 months of treatment with pembrolizumab proceed to the
      treatment continuation phase.

      CONTINUATION PHASE (ARMS A and C): Patients receive pembrolizumab IV over 30 minutes on day
      1. Patients also receive idelalisib orally (PO) twice daily (BID) on days 1-21 OR ibrutinib
      PO once daily (QD) on days 1-21. Treatment repeats every 21 days for up to 12 or 24 months in
      the absence of disease progression or unacceptable toxicity. Patients receiving benefit may
      continue to receive treatment for an additional 12 months at the discretion of the
      investigator.

      After completion of study treatment, patients are followed up every 3 months for 1 year.

Eligible Gender:All
Healthy Volunteers:No

Primary Outcome Measures

Measure:Proportion of patients who achieve a confirmed response
Time Frame:Up to 1 year
Safety Issue:
Description:Confirmed response is defined to be a partial response, nodular partial response, clinical complete response, confirmed response with incomplete blood count recovery or confirmed response (Arm A and B), or complete metabolic response, partial metabolic response, partial response, or confirmed response (Arm C). The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients. Exact binomial confidence intervals for the true success proportion will be calculated.

Secondary Outcome Measures

Measure:Complete response rate, defined as complete response or incomplete blood count recovery
Time Frame:Up to 1 year
Safety Issue:
Description:Estimated by the number of patients who achieve a incomplete blood count recovery or complete response divided by the total number of evaluable patients. All evaluable patients will be used for this analysis. Exact binomial 95% confidence intervals for the true complete response rate will be calculated.
Measure:Duration of response
Time Frame:Date at which the patient's objective status is first noted to be a partial or nodular partial response, clinical complete response, incomplete blood count recovery, or complete response to the earliest date relapse is documented, assessed up to 1 year
Safety Issue:
Description:The distribution of duration of response will be estimated using the method of Kaplan-Meier.
Measure:Incidence of adverse events as measured per National Cancer Institute-Common Terminology Criteria for Adverse Events version 4.0
Time Frame:Up to 1 year
Safety Issue:
Description:The maximum grade for each type of adverse event will be recorded for each patient, and frequency tables will be reviewed to determine patterns. Additionally, the relationship of the adverse event(s) to the study treatment will be taken into consideration. Adverse events will be evaluated for single-agent pembrolizumab in each arm and also for the combination of pembrolizumab and the signal inhibitor in Arm A and Arm C.
Measure:Overall response rate of patients treated with combination therapy
Time Frame:Up to 1 year
Safety Issue:
Description:Overall response rate will be estimated by the number of patients with an objective status of complete response, incomplete blood count recovery, nodular partial response, clinical complete response or partial response while on the combination therapy divided by the total number of evaluable patients. Exact binomial 95% confidence intervals for the true overall response rate to the combination will be calculated. In addition, the responders on this study will be further examined in an exploratory manner to determine if there are any patterns in prognostic factors or disease characteristics, in
Measure:Progression-free survival of patients treated with combination therapy
Time Frame:From initiation of treatment with the combination therapy to the earliest date of documentation of disease progression while on combination therapy or death due to any cause, assessed up to 1 year
Safety Issue:
Description:The distribution of progression-free survival will be estimated using the method of Kaplan-Meier.
Measure:Progression-free survival of patients treated with single pembrolizumab
Time Frame:The time from registration to the earliest date of documentation of disease progression or death due to any cause, assessed up to 1 year
Safety Issue:
Description:The distribution of progression-free survival will be estimated using the method of Kaplan-Meier.
Measure:Time to next treatment for patients on combination therapy
Time Frame:From initiation of combination therapy to the date of initiation of subsequent treatment for chronic lymphocytic leukemia/small lymphocytic lymphoma, assessed up to 1 year
Safety Issue:
Description:The distribution of time to next treatment will be estimated using the method of Kaplan-Meier.
Measure:Time to next treatment for patients treated with single-agent pembrolizumab
Time Frame:The time from registration to the date of initiation of subsequent treatment for chronic lymphocytic leukemia/small lymphocytic lymphoma or lymphoma, assessed up to 1 year
Safety Issue:
Description:The distribution of time to next treatment will be estimated using the method of Kaplan-Meier.
Measure:Treatment-free survival of patients treated with combination therapy
Time Frame:Time from initiation of combination therapy to the date of initiation of subsequent treatment for chronic lymphocytic leukemia/small lymphocytic lymphoma or death due to any cause, assessed up to 1 year
Safety Issue:
Description:The distribution of treatment-free survival will be estimated using the method of Kaplan-Meier.
Measure:Treatment-free survival of patients treated with single-agent pembrolizumab
Time Frame:The time from registration to the date of initiation of subsequent treatment for chronic lymphocytic leukemia/small lymphocytic lymphoma or lymphoma or death due to any cause, assessed up to 1 year
Safety Issue:
Description:The distribution of reatment-free survival will be estimated using the method of Kaplan-Meier.
