Brief Summary:
This phase II trial studies how well duvelisib on an intermittent (irregular) dosing schedule works in treating patients with chronic lymphocytic leukemia or small lymphocytic lymphoma. Duvelisib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving duvelisib on an intermittent schedule may result in similar effectiveness with less amount of severe side effects.

Condition or disease Intervention/treatment Phase
Recurrent Chronic Lymphocytic Leukemia Recurrent Small Lymphocytic Lymphoma Refractory Chronic Lymphocytic Leukemia Refractory Small Lymphocytic Lymphoma Drug: Duvelisib Phase 2

Detailed Description:

PRIMARY OBJECTIVE:

I. To evaluate the efficacy of duvelisib (induction followed by maintenance [intermittent dosing]) in patients with relapsed or refractory chronic lymphocytic leukemia (CLL), as measured by the progression free survival (PFS).

SECONDARY OBJECTIVES:

I. To evaluate safety of duvelisib induction and maintenance (by intermittent dosing) in relapsed/refractory CLL.

II. To evaluate clinical benefits to duvelisib treatment.

EXPLORATORY OBJECTIVE:

I. To evaluate T-cell populations in patients with CLL treated with duvelisib.

OUTLINE:

INDUCTION: Patients receive duvelisib orally (PO) twice daily (BID) on days 1-28. Cycles repeat every 28 days for 12 weeks in the absence of disease progression or unacceptable toxicity.

MAINTENANCE: Patients receive duvelisib PO BID on days 1-2, 8-9, 15-16, and 22-23. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for up to 12 months.

  • INK-1197
  • IPI-145




Primary Outcome Measures :
  1. Proportion of progression free survival (PFS) at 12 months [ Time Frame: First dose of duvelisib until death, time of progression, start of new therapy, or 12 months from start of therapy, whichever occurs first ]
    Proportion of subjects achieving 12 month PFS will be estimated along with a two-sided exact Clopper-Pearson 95% confidence interval.


Secondary Outcome Measures :
  1. Objective response rate (ORR) (including complete response [CR] and partial response [PR]) [ Time Frame: First dose of duvelisib up to 12 months after discontinuation of duvelisib ]
    Probability of having ORR will be measured and reported (if available) with 95% exact confidence interval.

  2. Median PFS [ Time Frame: First dose of duvelisib until death, time of progression, or start of new therapy, whichever occurs first, assessed up to 12 months after discontinuation of duvelisib ]
    Estimated distribution of the PFS will be plotted using Kaplan Meier curves and reported with median PFS and 95% confidence intervals if available.

  3. Duration of response (DOR) [ Time Frame: From time of ORR until death, time of progression, start of new therapy, or end of follow-up, whichever occurs first, assessed up to 12 months after discontinuation of duvelisib ]
    Descriptive statistics of DOR including mean, median, minimum, maximum, standard deviation, and 95% confidence interval will be reported.

  4. Incidence of toxicity [ Time Frame: From first dose of duvelisib until 3 months post-discontinuation of duvelisib ]
    Incidence of having grade 3+ acute toxicity will be determined for participants with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) that received at least one dose of duvelisib. The 95% confidence interval will be reported with the point estimate of toxicity rate.

  5. Duration of therapy [ Time Frame: From first dose of duvelisib until time of duvelisib discontinuation up to 5 years ]
    Estimate the duration of therapy from the first dose of study drug until therapy is discontinued for any reason. The proportion of subjects completing the induction phase will be reported including 95% confidence interval. Proportion who move prematurely to maintenance phase will be reported.


Other Outcome Measures:
  1. Percent distribution of circulating T-cells within duvelisib-treated CLL patients [ Time Frame: From first dose of duvelisib until 3 (end of induction), 6, and 12 cycles of therapy (each cyce is 28 days) ]
    Flow cytometry will be used to assess T-cell repertoire and evaluate changes associated with duvelisib. The distribution of T-cell subtypes distribution will be described by mean, standard deviation, minimal, and maximal values.
