|Chronic Lymphocytic Leukemia CLL Relapsed CLL Refractory Chronic Lymphocytic Leukemia Relapsed Chronic Lymphocytic Leukemia||Drug: Rituximab, Idelalisib, and Venetoclax||Phase 1|
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||42 participants|
|Intervention Model:||Single Group Assignment|
|Intervention Model Description:||Patients will start on dose level 1 of venetoclax in combination with rituximab and idelalisib, then escalate or de-escalate (if lower dose is available) based upon the estimated probabilities of toxicity from an extension of the continual reassessment method for 2 agents.|

Experimental: Rituximab, Idelalisib, & Venetoclax
Idelalisib 50, 100, or 150 mg PO BID; venetoclax 100 or 200 mg daily; rituximab per standard of care during the lead-in phase and then 500 mg/m2 IV every 4 weeks x 6 doses during the treatment phase
Drug: Rituximab, Idelalisib, and Venetoclax
Patients will start on dose level 1, then escalate or de-escalate (if lower dose is available) based upon the estimated probabilities of toxicity from an extension of the continual reassessment method for 2 agents.

- Recommended Phase 2 Dose (RP2D) of idelalisib and venetoclax in combination with rituximab [ Time Frame: 7 Years ]Recommended phase 2 dose of idelalisib and venetoclax in combination with rituximab in patients with relapsed or refractory CLL following a lead-in period with idelalisib and rituximab.
- Safety Evaluation: Determine adverse events (AEs) reported using criteria in the National Cancer Institute Common Terminology Criteria for Adverse Events Version 4.0 [ Time Frame: 7 Years ]Observed adverse events of treatment with idelalisib and venetoclax in combination with rituximab in patients with relapsed or refractory CLL following a lead-in period with idelalisib and rituximab utlizing CTCAE Version 4.0
- Determination of cumulative complete response (CR) rate. [ Time Frame: 7 Years ]Determine the cumulative CR rate to the triple-drug combination at 7 and 13 months using the 2008 International Workshop on Chronic Lymphocytic Leukemia (IWCLL) criteria.
- Summarize objective response rate. [ Time Frame: 7 Years ]Determine the cumulative overall disease response to the triple-drug combination at 7 and 13 months using the 2008 IWCLL criteria.
- Minimal residual disease (MRD) rate [ Time Frame: 7 Years ]To determine Minimal Residual Disease (MRD) negativity status in peripheral blood and/or bone marrow after achieving an objective response using 4-color flow cytometry in peripheral blood and/or bone marrow for responding patients.
- Survival Rate [ Time Frame: 7 Years ]Determine the proportion of patients who are alive at 24 months following initiation of venetoclax.
- Pharmacokinetics of the combination of idelalisib and venetoclax. [ Time Frame: 7 Years ]Determine the idelalisib and venetoclax plasma concentrations measured at designated time points throughout the study: pre-Tx; C1D1; C1D15; C1D22; C1D29; C3D1; C7D22; C13D222; at DLT (if feasible); at relapse (if feasible)]
