About this study
Official title: 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.
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).
Read the 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.

- Chronic Lymphocytic Leukemia

| Study group | Role | What they receive |
|---|---|---|
| IPI-145 | Experimental | Phase I-Dose escalation will occur using a standard 3-3 dose escalation beginning in dose level 1 with dose cohorts and escalation.
* Each treatment cycle lasts 28 days (except cycle 1, which is 35 days) during which time IPI-145 will be taken twice daily. The study begins with 1 week of IPI-145 monotherapy.
* Fludarabine, cyclophosphamide, rituximab (iFCR) - FCR will subsequently be introduced after 1 week and administered at standard dosing for up to 6 cycles, with dose reductions permitted. IPI-145 will be continued through the course of chemotherapy and for up to 2 years maintenance after completing chemotherapy Phase II - 20 additional patients treated with IPI-145 at the Recommended Phase II Dose (RP2D) + fludarabine, cyclophosphamide, rituximab (FCR) with standard dosing. Receives: Drug: IPI-145; Drug: Fludarabine; Drug: Cyclophosphamide; Drug: Rituximab |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Patients Who Experienced a Dose Limiting Toxicity (DLT) During Phase I
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
Measured: . 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
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)
Measured: 2 months after completion of combination therapy of IPI-145 and FCR
Secondary outcomes (9)
Overall Response Rate
Response and progression will be evaluated in this study using the 2008 IW-CLL criteria for CLL (Hallek et al., 2008)
Measured: At baseline, End of Cycle 3, and 2 months post FCR
Number of Participants With Serious and Non-Serious Adverse Events
Toxicity assessments will be done using the CTEP Version 4.0 of the NCI Common Terminology Criteria for Adverse Events (CTCAE) and will include all participants who have received at least 1 dose of IPI-145. Toxicities will be assessed at minimum every week during cycle 1, on Day 1 of every cycle during Cycle 2 onward, and every other cycle Day 1 during maintenance.
Measured: Up to 210 days
Rate of Minimal Residual Disease (MRD) in the Peripheral Blood
Participants will have MRD testing in the peripheral blood by four-color flow cytometry at the end of cycle 3, 2 months post combination therapy, and every 6 months thereafter for the duration of treatment and subsequent follow up
Measured: 2 Years
Rate of Treatment Related Adverse Effects
Participants will be evaluable for this endpoint if they have had at least 1 dose of study treatment. Toxicities will be assessed at minimum each week during cycle 1, and each day 1 during combination therapy, and then every two months thereafter. CTCAE version 4.0 will be used to assess toxicity term and grading.
Measured: 210 days
Determine the Association of Established CLL Prognostic Factors With Clinical Response
Fisher's exact test for categorical variables and Wilcoxon's rank sum test will be used-
Measured: 2 Years
Rate of Complete Response and Partial Response
Response and progression will be evaluated in this study using the 2008 IW-CLL criteria for CLL (Hallek et al., 2008)
Measured: At baseline, End of Cycle 3, and 2 months post FCR and then per investigator discretion thereafter
Rate of Progression Free Survival
2008 IW-CLL criteria
Measured: At baseline, End of Cycle 3, and 2 months post FCR and then per investigator discretion thereafter
Event Free Survival Rate
Response and progression will be evaluated in this study using the 2008 IW-CLL criteria for CLL (Hallek et al., 2008)
Measured: At baseline, End of Cycle 3, and 2 months post FCR and then per investigator discretion thereafter
Duration of Remission Rate
Response and progression will be evaluated in this study using the 2008 IW-CLL criteria for CLL (Hallek et al., 2008)Frequency of follow up visits and scans are per MD discretion. Recommended follow up visits for a minimum of one year
Measured: At baseline, End of Cycle 3, and 2 months post FCR and then per investigator discretion thereafter
