About this study
Official title: Phase I/II Study of the Combination of Bendamustine, Rituximab and MK-2206 in the Treatment of Relapsed Chronic Lymphocytic Leukemia and Small Lymphocytic Lymphoma
This phase I/II trial studies the side effects and best dose of v-akt murine thymoma viral oncogene homolog 1 (Akt) inhibitor MK2206 when given together with bendamustine hydrochloride and rituximab and to see how well they work in treating patients with refractory chronic lymphocytic leukemia or small lymphocytic lymphoma. Akt inhibitor MK2206 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as bendamustine hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Giving Akt inhibitor MK2206 with bendamustine hydrochloride and rituximab may be an effective treatment for relapsed chronic lymphocytic leukemia or small lymphocytic lymphoma.
Read the detailed description
PRIMARY OBJECTIVES:
- To assess the safety and maximum tolerated dose (MTD) of MK-2206 (Akt inhibitor MK2206) in combination therapy with bendamustine (bendamustine hydrochloride)-rituximab in relapsed chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) patients. (Phase I) II. To assess the rate of complete response (CR) of MK-2206 in combination with bendamustine-rituximab in relapsed CLL or SLL patients. (Phase II)
SECONDARY OBJECTIVES:
- To assess clinical efficacy of MK-2206 in combination with bendamustine-rituximab as demonstrated by analysis of overall response rate (CR, complete response with incomplete bone marrow recovery [CRi], clinical complete response [CCR], near partial response [nPR] and partial response [PR]), duration of response, and treatment free survival.
II. To assess the toxicity profile of MK-2206 in combination with bendamustine-rituximab.
TERTIARY OBJECTIVES:
- Evaluation of whether the established CLL prognostic factors (cluster of differentiation [CD]38, CD49d, immunoglobulin heavy chain variable [IGHV], fluorescence in situ hybridization [FISH] and zeta-chain-associated protein kinase 70 [ZAP-70]) predict responses to the combination therapy of MK2206, with bendamustine-rituximab.
II. Minimal residual disease will be evaluated after treatment in patients who achieve a clinical response; minimal residual disease (MRD) status will be explored in relation to both the quality and duration of response.
III. Evaluation of the effects of the addition of MK-2206 to bendamustine-rituximab on B cell receptor initiated, phosphoinositide 3-kinase (PI3K)/Akt downstream signal pathways, apoptosis analysis and leukemic cell activation status, as well as multiple cytokine profiles and key gene expression analysis with focus on leukemic cells.
IV. Evaluation of marrow stromal cells (MSC)-CLL biology including the effects of the addition of MK-2206 to bendamustine-rituximab on CLL marrow stromal cell (MSC) proliferation, migration and cytokine production, as well as the adhesion capacity between MSC and leukemic cells.
OUTLINE: This is a phase I, dose-escalation study of Akt inhibitor MK2206 followed by a phase II study.
Patients receive Akt inhibitor MK2206 orally (PO) on days 1, 8, 15, and 22 (days 1, 8, 15, 22, and 29 of course 1); rituximab intravenously (IV) on day 1 (day 8 of course 1); and bendamustine hydrochloride IV over 30-60 minutes on days 1-2 (days 8-9 of course 1). Treatment repeats every 28 days (35 days for course 1 and 84 days for course 6) for 6 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 or 12 months for 3 years.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Phase I Participants With Dose-Limiting Toxicity Events (Phase I)
The Maximum Tolerated Dose (MTD) is defined as the dose level below the lowest dose that induces dose-limiting toxicity (DLT) in at least one-third of patients graded according to NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. Dose-limiting toxicities include non-hematologic events graded 3 or higher and deemed at least possibly related to treatment. A total of 6 patients treated at the MTD will be sufficient to identify common toxicities at the MTD.The number of patients reporting a dose-limiting event are reported.
Measured: Up to 35 days
Proportion of Complete Response Defined to be a CR or CRi Noted as the Objective Status (Phase II)
A Complete Response (CR) is defined by the NCI Working Group criteria and requires all of the following for a period of at least 2 months:
- Absence of lymphadenopathy (e.g. lymph nodes >1.5 cm) by physical examination.
- No hepatomegaly or splenomegaly by physical examination.
- Absence of constitutional symptoms.
- Neutrophils ≥1500/ul.
- Platelets >100,000/ul (untransfused).
- Hemoglobin >11.0 gm/dl (untransfused)
- Peripheral blood lymphocytes <4000/uL
Patients who fulfill all criteria for a CR but who have a persistent anemia, thrombocytopenia, or neutropenia related to drug toxicity rather than residual CLL will be classified as CR with incomplete marrow recovery (CRi).
The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients. Confidence intervals for the true success proportion will be calculated according to the approach of Duffy and Santner.
Measured: From registration to response, up to 84 days
Secondary outcomes (7)
Biomarker Analysis (IgVH Gene Mutation)
IgVH gene mutationwill be evaluated pre-treatment. This factors will be summarized and used to help characterize the types of patients accrued to this trial.
Measured: Baseline
Biomarker Analysis (CD38, CD49d, and ZAP-70)
CD38, CD49d, and ZAP-70 status will be evaluated pre-treatment. These factors will be summarized and used to help characterize the types of patients accrued to this trial.
Measured: Baseline
Fluorescent in Situ Hybridization (FISH) Biomarker Analysis
Fluorescent in situ hybridization (FISH) is a molecular cytogenetic technique that uses fluorescent probes that bind to only those parts of the chromosome with a high degree of sequence complementarity. It was developed by biomedical researchers in the early 1980s and is used to detect and localize the presence or absence of specific DNA sequences on chromosomes. In this disease group, there are recognized patterns of DNA sequences that play a role in prognostic outcomes. Patterns named 11q-, 13q-, Trisomy 12 may lead to different responses to treatments. Here we report the number of patients with each FISH prognosis evaluated pre-treatment. These factors will be summarized and used to help characterize the types of patients accrued to this trial.
Measured: Baseline
Duration of Response
Duration of response is defined for all evaluable patients who have achieved a clinical response as the date at which the patient's objective status is first noted to be a CR, CRi, CCR, nPR, or PR to the earliest date progression is documented. The distribution of duration of response will be estimated using the method of Kaplan-Meier.
Measured: Median follow-up of 39 months and maximum follow-up of 54 months
Minimal-residual Disease
Minimal residual disease (MRD) will be evaluated after treatment in patients who achieve a complete clinical response. Flow cytometry will be used to detect approximately 1 CLL cell per 10,000 leukocytes following induction. A score of positive means CLL cells were found and a negative score means no CLL cells were found. The number of patients with an MRD negative score are reported here.
Measured: Cycle 6 assessment (maximum of 231 days post-registration)
Overall Response Rate
The Overall response rate is estimated by the total number of complete or partial responses (CR, CRi, CCR, nPR, or PR) divided by the total number of evaluate patients. Complete and partial responses were scored using the NCI Working Group criteria. A Complete Response (CR, CRi, and CCR) is characterized by an absence of lymphadenopathy, heptomegaly and splenomegaly with or without normalized blood counts and bone marrow assessment . A PR is defined as having >50% decrease in lymphocyte count and reduction in sum of the products of measured nodes and an improvement in blood counts. Exact binomial 95% confidence intervals for the true overall response rate will be calculated.
Measured: 3 months post-treatment
Treatment-free Survival
Treatment free survival is defined to be the time from registration to the date of initation of subsequent therapy or death. The distribution of treatment free survival will be estimated using the method of Kaplan-Meier.
Measured: Time from registration to the date of initiation of subsequent therapy or death, median follow-up time is 37 months

Primary outcome
Number of Phase I Participants With Dose-Limiting Toxicity Events (Phase I)
Time frame: Up to 35 days
The Maximum Tolerated Dose (MTD) is defined as the dose level below the lowest dose that induces dose-limiting toxicity (DLT) in at least one-third of patients graded according to NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. Dose-limiting toxicities include non-hematologic events graded 3 or higher and deemed at least possibly related to treatment. A total of 6 patients treated at the MTD will be sufficient to identify common toxicities at the MTD.The number of patients reporting a dose-limiting event are reported.
Proportion of Complete Response Defined to be a CR or CRi Noted as the Objective Status (Phase II)
Time frame: From registration to response, up to 84 days
A Complete Response (CR) is defined by the NCI Working Group criteria and requires all of the following for a period of at least 2 months: * Absence of lymphadenopathy (e.g. lymph nodes >1.5 cm) by physical examination. * No hepatomegaly or splenomegaly by physical examination. * Absence of constitutional symptoms. * Neutrophils ≥1500/ul. * Platelets >100,000/ul (untransfused). * Hemoglobin >11.0 gm/dl (untransfused) * Peripheral blood lymphocytes <4000/uL Patients who fulfill all criteria for a CR but who have a persistent anemia, thrombocytopenia, or neutropenia related to drug toxicity rather than residual CLL will be classified as CR with incomplete marrow recovery (CRi). The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients. Confidence intervals for the true success proportion will be calculated according to the approach of Duffy and Santner.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Akt Inhibitor MK2206, Bendamustine Hydrochloride and Laboratory Biomarker Analysis in people with Chronic Lymphocytic Leukemia and Recurrent Small Lymphocytic Lymphoma, run by National Cancer Institute (NCI) at 44 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 38 inclusion and 60 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Sep 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 44 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 28 Jun 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Phase I Participants With Dose-Limiting Toxicity Events (Phase I) (time frame: Up to 35 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Sep 2017.
