Determine the overall response rate after 6 cycles of treatment with daratumumab in combination with ibrutinib in patients who are naive to ibrutinib treatment. (Cohort 2)
SECONDARY OBJECTIVES:
I. Determine the best overall response rate to treatment with daratumumab plus ibrutinib at any time during the course of the therapy. (Cohort 1) II. The overall incidence of MRD (minimal residual disease) negative state and the time to achieving MRD negativity at any time during this therapy. (Cohort 1) III. Progression free survival (as determined by the International Workshop on Chronic Lymphocytic Leukemia [IWCLL] criteria) among all patients. (Cohort 1) IV. The overall toxicity profile of daratumumab/ibrutinib treatment in this group of patients. (Cohort 1) V. Determine the best overall response rate to treatment with daratumumab plus ibrutinib at any time during the course of the therapy. (Cohort 2) VI. The overall incidence of MRD (minimal residual disease) negative state and the time to achieving MRD negativity at any time during this therapy. (Cohort 2) VII. The overall toxicity profile of daratumumab/ibrutinib treatment in this group of patients. (Cohort 2)
OUTLINE:
Patients receive daratumumab intravenously (IV) on days 1, 8, 15, and 22 of cycles 1-2, on days 1 and 15 of cycles 3-6, and then on day 1 of subsequent cycles. Beginning in cycle 2, patients also receive ibrutinib orally (PO) once daily (QD) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study registration, patients are followed up periodically for up to 5 years.

Exclusion Criteria:
- Any serious medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from signing the informed consent form
- Patient is known to have chronic obstructive pulmonary disease with a forced expiratory volume in 1 second (FEV1) < 50% of predicted normal (Note: FEV1 testing is required for subjects suspected of having chronic obstructive pulmonary disease and subjects must be excluded if FEV1 < 50% of predicted normal)
- Patient is known to have moderate or severe persistent asthma within the past 2 years, or currently has uncontrolled asthma of any classification (Note: subjects who currently have controlled intermittent asthma or controlled mild persistent asthma are allowed in the study)

- Pregnant women
- Nursing women
- Men or women of childbearing potential who are unwilling to employ adequate contraception
- Any condition, including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she were to participate in the study or confounds the ability to interpret data from the study

- Exposure to an investigational drug (including investigational vaccine) or invasive investigational medical device for any indication within 4 weeks or 5 pharmacokinetic half-lives, whichever is longer.
- Focal radiation therapy within 14 days prior to randomization with the exception of palliative radiotherapy for symptomatic management but not on measurable extramedullary plasmacytoma
- Concomitant use of warfarin or other vitamin K antagonists

Subjects with resolved infection (i.e., subjects who are HBsAg negative but positive for antibodies to hepatitis B core antigen [anti-HBc] and/or antibodies to hepatitis B surface antigen [anti-HBs]) must be screened using real-time polymerase chain reaction (PCR) measurement of hepatitis B virus (HBV) deoxyribonucleic acid (DNA) levels. Those who are PCR positive will be excluded. EXCEPTION: Subjects with serologic findings suggestive of HBV vaccination (anti-HBs positivity as the only serologic marker) AND a known history of prior HBV vaccination, do not need to be tested for HBV DNA by PCR
- Seropositive for hepatitis C (except in the setting of a sustained virologic response [SVR], defined as aviremia at least 12 weeks after completion of antiviral therapy)

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Overall response rate
Time Frame: At the completion of cycle 7
|
Will be evaluated in each cohort independently.
A response is defined as an objective status of complete response (CR), CR with incomplete marrow recovery (CRi), complete clinical response (CCR), nodular partial response (nPR), or PR after 6 cycles of combination treatment.
In each cohort, the proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients.
Ninety-five percent exact binomial confidence intervals for the true success proportion will be calculated.
|
At the completion of cycle 7
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Overall response rate
Time Frame: Up to 5 years
|
Will be evaluated in each cohort independently.
Will be estimated by the number of patients who achieve a CR, CRi, CCR, nPR, or PR at any time during combination treatment divided by the total number of evaluable patients.
Exact binomial 95% confidence intervals for the true success rate will be calculated.
|
Up to 5 years
|
Minimal residual disease (MRD) response rate
Time Frame: Up to 5 years
|
Will be evaluated in each cohort independently.
Will be estimated by the number of patients who achieve MRD negative response in both blood and bone marrow at any time during combination treatment divided by the total number of evaluable patients.
Exact binomial 95% confidence intervals for the true success rate will be calculated.
In patients who achieve MRD negative response, time to achieve MRD negative response will be summarized descriptively (median, range).
Time to achieve MRD negative response is defined as time from registration to the earliest date of documentation of MRD negative response in both blood and bone marrow.
|
Up to 5 years
|
Progression-free survival
Time Frame: From registration to the earliest date of documentation of disease progression or death due to any cause, assessed up to 5 years
|
Will be evaluated in each cohort independently.
The distribution of progression-free survival will be estimated using the method of Kaplan-Meier.
|
From registration to the earliest date of documentation of disease progression or death due to any cause, assessed up to 5 years
|
Incidence of adverse events
Time Frame: Up to 30 days after completion of study treatment
|
Will be evaluated in each cohort independently.
Platelets and hemoglobin will be graded according to the Grading Scale for Hematologic Adverse Events in Chronic Lymphocytic Leukemia (CLL) Studies.
The maximum grade for each type of adverse event, regardless of causality, will be recorded and reported for each patient, and frequency tables will be reviewed to determine adverse event patterns.

Up to 30 days after completion of study treatment
