A Phase 1b/2 Study of IPI-145 Plus FCR in Previously Untreated, Younger Patients With CLL
A Phase 1b/2 Study of IPI-145 in Combination With Fludarabine, Cyclophosphamide, and Rituximab (iFCR) in Previously Untreated, Younger Patients With Chronic Lymphocytic Leukemia.

Intervention / Treatment
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.

Accepts Healthy Volunteers
Description
Inclusion Criteria:

- no prior therapy for CLL
- age 18-65 -- ECOG performance status ≤1
Exclusion Criteria:
- May not be receiving any other study agents
- Known CNS involvement
- Uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
- Pregnant women are excluded from this study because IPI-145 has the potential for teratogenic or abortifacient effects.
- Individuals with a history of a different malignancy are ineligible except for the following circumstances. disease-free for at least 5 years and deemed to be at low risk for recurrence. Individuals with the following cancers are eligible if diagnosed and treated with curative intent within the past 5 years: cervical cancer in situ, localized prostate cancer, and basal cell or squamous cell carcinoma of the skin
- HIV-positive individuals, because of the potential for pharmacokinetic interactions with IPI-145
- Inadequate hepatic function defined by aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) >2.5 x upper limit of normal (ULN); direct bilirubin >1.5 x ULN, unless due to hemolysis or Gilbert's syndrome
- Inadequate renal function defined by serum creatinine >1.5 x ULN.
- Baseline QTcF >480 ms. NOTE: This criterion does not apply to patients with a left bundle branch block
- Concurrent treatment with any agent known to prolong the QTc interval
- Patients with a history of active tuberculosis within the preceding two years.
- Patients who have had a venous thromboembolic event (e.g., PE/DVT) requiring anticoagulation and who meet any of the following criteria:
- Have been on a stable dose of anticoagulation for <1 month
- Have had a Grade 2, 3 or 4 hemorrhage in the last 30 days
- Are experiencing continued symptoms from their event
- History of alcohol abuse, chronic hepatitis, or other chronic liver disease (other than direct CLL liver involvement)
- Foods or medications that are strong or moderate inhibitors or inducers of CYP3A taken within 1 week prior to study treatment and for the duration of the study
- Unable to receive prophylactic treatment for pneumocystis

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Patients Who Experienced a Dose Limiting Toxicity (DLT) During Phase I
Time Frame: . 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/RP2D
|
To 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
|
. 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/RP2D
|
Number of Patients Who Had a Minimal Residual Disease (MRD) Negative Complete Response (CR) 2 Months After Chemotherapy
Time Frame: 2 months after completion of combination therapy of IPI-145 and FCR
|
To 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)
