About

This phase II trial studies the side effects of nivolumab and/or ipilimumab with or without azacitidine and to see how well they work in treating patients with myelodysplastic syndrome. Monoclonal antibodies, such as nivolumab and ipilimumab, may block cancer growth in different ways by targeting certain cells. Drugs used in chemotherapy, such as azacitidine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving nivolumab and/or ipilimumab with or without azacitidine may work better in treating myelodysplastic syndrome.

Full description

PRIMARY OBJECTIVES:

I. To determine the safety of nivolumab and ipilimumab, as single agents or in combination and with 5-azacitidine (azacitidine), in patients with myelodysplastic syndrome (MDS).

SECONDARY OBJECTIVES:

I. To explore the clinical activity of nivolumab and ipilimumab, as single agents or in combination and with 5-azacitidine, in patients with MDS.

II. To explore the biological activity of these compounds in patients with MDS.

OUTLINE: Patients are assigned to 1 of 6 cohorts. Patients with hypomethylating failure MDS are assigned to cohorts I, II, or III. Patients with previously untreated MDS are assigned to cohorts IV, V, or VI.

COHORT I (COHORT COMPLETED AS OF 10/7/19): Patients receive nivolumab intravenously (IV) over 30 minutes on days 1 and 15. Treatment repeats every 4 weeks for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients with disease progression may receive nivolumab and azacitidine at the discretion of the treating physician.

COHORT II (COHORT COMPLETED AS OF 10/7/19): Patients receive ipilimumab IV over 30 minutes on day 1. Cycles repeat every 3 weeks in the absence of disease progression or unacceptable toxicity. Patients with disease progression may receive ipilimumab and azacitidine at the discretion of the treating physician.

COHORT III: Patients receive nivolumab IV over 30 minutes on days 1 and 15 and ipilimumab IV over 30 minutes on day 1. Treatment repeats every 4 weeks for up to 4 cycles in the absence of disease progression or unacceptable toxicity. Patients then receive nivolumab IV over 30 minutes every 2 weeks (or every 4 weeks if patients receive azacitidine) in the absence of disease progression or unacceptable toxicity. Patients with disease progression may receive ipilimumab, nivolumab, and azacitidine at the discretion of the treating physician.

COHORT IV (COHORT COMPLETED AS OF 10/7/19): Patients receive azacitidine IV over 10-40 minutes on days 1-5 and nivolumab IV over 30 minutes on days 6 and 20. Cycles repeat every 4 weeks in the absence of disease progression or unacceptable toxicity.

COHORT V: Patients receive azacitidine IV over 10-40 minutes on days 1-5 and ipilimumab IV over 30 minutes on day 6. Cycles repeat every 4 weeks in the absence of disease progression or unacceptable toxicity.

COHORT VI (COHORT ON-HOLD AS OF 10/7/19): Patients receive azacitidine IV over 10-40 minutes on days 1-5 and nivolumab IV over 30 minutes and ipilimumab IV over 30 minutes on day 6. Treatment with ipilimumab repeats every 4 weeks for 4 cycles in the absence of disease progression or unacceptable toxicity. Cycles with nivolumab and azacitidine repeat every 4 weeks in the absence of disease progression or unacceptable toxicity.

Inclusion criteria

• Patients with MDS (up to 20% blasts) of any risk as defined as:

  • Previously untreated
  • Previously treated with hypomethylating agent (HMA) agent; patients need to have relapsed or progressed after any number of cycles of HMA therapy; patients that do not respond to HMA therapy will also be allowed in the study; relapse or progression will be measured by International Working Group (IWG) 2006 criteria; no response will be lack of clinical benefit after at least 6 cycles of HMA therapy

• Eastern Cooperative Oncology Group (ECOG) performance status =< 2

• Females of childbearing potential must have a negative serum or urine beta human chorionic gonadotropin (beta-hCG) pregnancy test result within 24 hours prior to the first dose of treatment and must agree to use an effective contraception method to avoid pregnancy for 23 weeks (30 days plus the time required for nivolumab to undergo five half-lives) after the last dose of investigational drugs; females of non-childbearing potential are those who are postmenopausal greater than 1 year or who have had a bilateral tubal ligation or hysterectomy

• Males who have partners of childbearing potential must agree to use an effective contraceptive method during the study and a period of 31 weeks after the last dose of investigational drug

• Patients or their legally authorized representative must provide written informed consent

Exclusion criteria

• Second malignancy currently requiring active therapy, except breast or prostate cancer stable on or responding to endocrine therapy
• Any major surgery, radiotherapy, chemotherapy, biologic therapy, immunotherapy, experimental therapy within 2 weeks prior to the first dose of the study drugs
• Patients with any other known concurrent severe and/or uncontrolled medical condition (e.g. uncontrolled diabetes; cardiovascular disease including congestive heart failure New York Heart Association [NYHA] class III or IV, myocardial infarction within 6 months, and poorly controlled hypertension; chronic renal failure; or active uncontrolled infection) which, in the opinion of the investigator could compromise participation in the study
• Patients unwilling or unable to comply with the protocol
• History of pneumonitis
• Patients who are on high dose steroid (equivalent of prednisone more than 10 mg a day) or immune suppression medications
