Brief summary

This research study is evaluating a new drug called IPI-145 in combination with the standard drugs fludarabine, cyclophosphamide, and rituximab (FCR), as a possible treatment for chronic lymphocytic leukemia (CLL).

Detailed description

Patients who fulfill eligibility criteria will be entered into the trial to receive IPI-145 in combination with the standard drugs fludarabine, cyclophosphamide, and rituximab (FCR). After the screening procedures confirm participation in the research study: Phase I The investigators are looking for the highest dose of the combination of study drugs that can be administered safely without severe or unmanageable side effects in participants that have CLL. Not everyone who participates in this research study will receive the same dose of the study drug. The dose given will depend on the number of participants who have been enrolled in the study prior and how well the dose was tolerated. Phase II: Patients treated with IPI-145 at the Recommended Phase II Dose (RP2D) + fludarabine, cyclophosphamide, rituximab (FCR) with standard dosing.

Number of Patients Who Experienced a Dose Limiting Toxicity (DLT) During Phase I. Participants were assessed every week or more often as needed during Cycle 1, and every Day 1 Cycles 2 and onward-Dose-limiting toxicities (DLTs) occurring during the first cycle of treatment will be used in determining the Phase II MTD/RP2DTo assess the safety of IPI145 in combination with FCR in previously untreated younger patients with CLL. DLT is based on the Common Terminology Criteria for Adverse Events (CTCAE) Version 4.0. DLT refers to toxicities experienced at any time during the study treatment, defined as Grade 3 or greater hematologic toxicity (except Grade 3 or Grade 4 neutropenia or thrombocytopenia that lasts less than or equal to 10 days off treatment), any Grade 3 or greater non-hematologic toxicity (except Grade 3 or greater nausea, vomiting, diarrhea, Grade 3 infusion reactions), Grade 3 asymptomatic laboratory abnormalities that improve to grade 2 or less within 3 days, Inability to receive day 1 therapy of Cycle 2 even after a three week treatment delay due to drug related toxicity from prior cycle, and any Grade 4 or greater elevation in AST ALT values
Number of Patients Who Had a Minimal Residual Disease (MRD) Negative Complete Response (CR) 2 Months After Chemotherapy2 months after completion of combination therapy of IPI-145 and FCRTo determine the rate of minimal residual disease negative complete response (MRD negative CR) in the bone marrow at 2 months post last cycle of FCR, participants will have a bone marrow biopsy procedure 2 months after completing combination therapy (IPI-145+ FCR) in tandem with a chest,neck, abdomen and pelvic PET CT scan. A central read of the PET CT scan will confirm a radiographic complete response, and the bone marrow pathology and morphology assessments will confirm morphological CR in the bone marrow, while MRD testing will be done by four-color flow cytometry on the bone marrow aspirate with a detection level of 10-4. This will include all patients treated and evaluable at maximum tolerated dose, and at the recommended phase II dose ( RP2D)
