Brief Summary:
This is an open‑label non‑randomized two‑center phase 2 study evaluating the safety and efficacy of concurrent therapy with ibrutinib and venetoclax in subjects with relapsed or refractory CLL/SLL.

Condition or disease Intervention/treatment Phase
Recurrent Chronic Lymphocytic Leukemia Recurrent Small Lymphocytic Lymphoma Refractory Chronic Lymphocytic Leukemia Refractory Small Lymphocytic Lymphoma Drug: Ibrutinib Other: Laboratory Biomarker Analysis Other: Pharmacological Study Drug: Venetoclax Phase 2

Detailed Description:

The primary objective of this study is to evaluate the efficacy of concurrent therapy with ibrutinib and venetoclax in patients with relapsed and refractory chronic lymphocytic leukemia (CLL) and small lymphocytic leukemia (SLL).

The secondary objectives of this study are to define the safety, tolerability, and dose‑limiting toxicity (DLT) within 28 days of completion of dose‑escalation.

Primary Outcome Measures :
  1. Complete Response Rate [ Time Frame: one year ]
    The proportion of subjects with a complete response (per investigator assessment) will be calculated for all subjects based on IWCLL criteria. A 95% confidence interval based on binomial distribution will be constructed for the calculated CR rate.


Secondary Outcome Measures :
  1. Duration of response [ Time Frame: From the date of first response per investigator assessment to the earliest recurrence or progressive disease per investigator assessment, assessed up to 3 years ]
    Will be analyzed by Kaplan-Meier methodology using data for all enrolled subjects. Median duration of response will be calculated and the corresponding 95% confidence interval will be presented.

  2. Minimal residual disease (MRD) negativity rate in bone marrow [ Time Frame: Up to 3 years ]
    MRD negativity will be defined as less than one CLL cell per 10,000 leukocytes (or below 10-4) on bone marrow based flow cytometry. Rate of MRD negativity will be defined as the proportion of subjects who achieve MRD negativity status. Ninety-five percent (95%) confidence intervals based on the binomial distribution will be provided.

  3. Overall response rate (ORR) [ Time Frame: Up to 3 years ]
    The proportion of subjects with an overall response (per investigator assessment) will be calculated for all subjects based on IWCLL NCI collaborative WG criteria. A 95% confidence interval based on binomial distribution will be constructed for the calculated ORR.

  4. Overall survival [ Time Frame: From the date of first dose to the date of death for all dosed subjects, assessed up to 3 years ]
    Will be analyzed by Kaplan-Meier methodology using data from all dosed subjects. Median time survival will be calculated and 95% confidence interval for the median time survival will be presented.

  5. Progression-free survival (PFS) [ Time Frame: From the date of first dose to the date of earliest disease progression (per the investigator assessment) or death, assessed up to 3 years ]
    Will be analyzed by Kaplan-Meier methodology using data for all dosed subjects. Median PFS time will be calculated and 95% confidence interval for median PFS time will be presented.

  6. Time-to-progression (TTP) [ Time Frame: From the date of first dose (date of enrollment if not dosed) to the date of earliest disease progression (per the investigator assessment), assessed up to 3 years ]
    Will be analyzed by Kaplan-Meier methodology using data for all enrolled subjects. Median time TTP will be calculated and 95% confidence interval for median time TTP will be presented.


Other Outcome Measures:
  1. Time to next anti-CLL treatment (TTNT) [ Time Frame: From the date of the first dose of ibrutinib to the date of first dose of new non-protocol anti-leukemia therapy or death from any cause, assessed up to 3 years ]
    Will be analyzed by Kaplan-Meier methodology using data for all dosed subjects. Median TTNT time will be calculated.
