Study Overview
Status
Conditions
Detailed Description
PRIMARY OBJECTIVE:
I. To determine the efficacy (as assessed by complete response [CR] rate) of the combination of ixazomib citrate (ixazomib) and ibrutinib in Waldenstrom macroglobulinemia (WM) patients.
SECONDARY OBJECTIVES:
I. To assess the overall response rate (ORR=partial response [PR] or better) in WM patients treated with ixazomib and ibrutinib.
II. To assess the time to progression (TTP) in WM patients treated with ixazomib and ibrutinib.
III. To further characterize the safety and toxicity of the combination of ibrutinib and ixazomib.
IV. To assess the overall survival (OS) in WM patients treated with ixazomib and ibrutinib.
CORRELATIVE RESEARCH OBJECTIVES:
I. To determine the role of members of the BTK signalosome in achievement or lack thereof of response to ibrutinib and ixazomib.
II. To explore biologic effects of ibrutinib and ixazomib on microenvironment in WM and correlate with response to treatment.
OUTLINE:
Patients receive ixazomib citrate orally (PO) on days 1, 8, and 15 and ibrutinib PO daily on days 1-28. Treatment repeats every 28 days for up to 24 cycles in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for up to 2 years.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Complete response rate (CR)
Time Frame: Up to 5 years
|
Complete response rate to be defined as an objective status of CR at any time, where confirmation of the complete response status is required on two consecutive evaluations with a second immunofixation before calling the patient a CR.
The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients.
95% confidence intervals for the true success proportion will be calculated according to the approach of Duffy and Santner.
|
Up to 5 years
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Overall response rate
Time Frame: Up to 5 years
|
Overall response rate will be estimated by the total number of patients who achieve a CR, very good partial response (VGPR), or partial response (PR) 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 overall response rate will be calculated.
|
Up to 5 years
|
Time to progression
Time Frame: From study registration to the earliest date of documentation of disease progression, assessed up to 5 years
|
The distribution of time to progression will be estimated using the method of Kaplan-Meier.

Incidence of adverse effects (AE) graded according to Common Terminology Criteria for Adverse Events (CTCAE) version (v.) 4.0

Other Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
BTK signaling proteins (western blot and densitometric quantification) and gene expression (quantitative real-time polymerase chain reaction [PCR]) examined in CD19/CD138+ Waldenstrom macroglobulinemia (WM) cells
Time Frame: Up to 5 years
|
15 protein/genes associated with BTK-signaling will be assessed and their levels from baseline samples will be compared with levels from samples during treatment.
Changes over time will be evaluated using paired sample approaches (Wilcoxon signed rank test).
Baseline levels will be correlated with response (responder versus [vs.] non-responder) using Wilcoxon rank sum tests.

Biologic effects of ibrutinib and ixazomib citrate on microenvironment in WM
Time Frame: Up to 5 years
|
Blood samples & bone marrow aspirate to be taken from participants.
The study will explore biologic effects of ibrutinib and ixazomib on microenvironment in WM and correlate with response to treatment.
Immunophenotyping of tumor infiltrating lymphocytes (TILs) using the Multi-Omyx TILs platform.
This will identify 17 different types of TILs from BM samples collected at baseline and then after one cycle of treatment.
This data is represented as % and actual cell counts.
Next, identification of 4 types of T-cells from the blood.
This will be done from peripheral blood samples collected at Baseline and then after one cycle of treatment with ixazomib + ibrutinib (Ixa+Ibr).
Next, BTK receptor occupancy: This is a competitive-binding assay essentially and will be performed in CD19+/CD138+ WM cells collected at baseline and then after one cycle of treatment with Ixa+Ibr.
Readout is % occupancy.
Values to be correlated with response (responder vs. non-responder) using Wilcoxon rank sum tests.
