  Purpose

This phase I trial studies the side effects and best dose of ipilimumab in treating patients with relapsed or refractory high-risk myelodysplastic syndrome or acute myeloid leukemia. Monoclonal antibodies, such as ipilimumab, 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.

Primary Outcome Measures:
  • Dose-limiting toxicity of ipilimumab by grading and tabulation using National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Version 4.0 [ Time Frame: 42 days ] [ Designated as safety issue: Yes ]
  • Functional dynamics of T-regs in terms of frequency and function [ Time Frame: Up to 6 months ] [ Designated as safety issue: No ]
    Lymphocyte counts and T cell receptor diversity at baseline will be summarized and compared between response and toxicity groups with either t tests or Wilcoxon rank sum tests.


Secondary Outcome Measures:
  • Efficacy as defined by the International working group 2006 (IWG-2006) criteria for CR, PR, HI [ Time Frame: Up to 6 months ] [ Designated as safety issue: No ]
    Regression models that use generalized estimating equations (GEE) will be implemented when all time points are considered to account for within-subject correlation of repeated measures. The agreement between immunologic and clinical response will be evaluated with McNemar's test, separately by cohort. 95% confidence limits will be provided as appropriate.

  • Progression free survival (PFS) [ Time Frame: From start of study to progression or death, assessed up to 2 years ] [ Designated as safety issue: No ]
    Will be reported with a 95% confidence interval.

  • Overall survival (OS) [ Time Frame: From start of study to death, assessed up to 2 years ] [ Designated as safety issue: No ]
    Will be reported with a 95% confidence interval.

Detailed Description:

PRIMARY OBJECTIVES:

I. Evaluate the safety and toxicity associated with the administration of ipilimumab in terms of dose limiting toxicities (DLT), and maximally-tolerated dose (MTD) in a cohort of patients with high risk myelodysplastic syndrome who failed hypomethylating therapy, and patients with acute myeloid leukemia (AML) who underwent induction therapy but are not planned for further intensive chemotherapy.

II. Determine the optimal dose of ipilimumab for the dose-expansion phase of the trial.

III. Better define immunologic profiles associated with ipilimumab use in terms of regulatory T-cells (T-regs) dynamic changes in 2 separate cohorts of myelodysplastic syndrome (MDS) and AML patients at the optimal dose level.

IV. Obtain preliminary efficacy data of ipilimumab in terms of complete response (CR), partial response (PR), and hematological improvement (HI) in both cohorts.

SECONDARY OBJECTIVES:

I. Define immunologic profiles associated with ipilimumab use in terms of T-regs dynamic changes at different dose levels.

II. Define toxicity profiles of ipilimumab at the optimal dose in both patient cohorts.

III. Obtain preliminary data on potential correlations between noted ipilimumab-induced immunologic changes and observed toxicity and clinical responses.

OUTLINE: This is a dose-escalation study.

INDUCTION: Patients receive ipilimumab intravenously (IV) on day 1. Treatment repeats every 21 days for up to 4 courses in the absence of disease progression or unacceptable toxicity.

MAINTENANCE: Patients receive ipilimumab IV on day 1. Treatment repeats every 12 weeks for up to 4 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up monthly for 6 months.

  • Patients with known other cancers, including brain metastases
  • Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier
