Clinical Trial Summary

This phase II trial studies the side effects and best dose of nivolumab and azacitidine with or without ipilimumab when given together and to see how well they work in treating patients with acute myeloid leukemia that has not responded to previous treatment or has returned after a period of improvement or is newly diagnosed. Monoclonal antibodies, such as nivolumab and ipilimumab, may interfere with the ability of cancer cells to grow and spread. 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, azacitidine and ipilimumab may kill more cancer cells.

Description:

PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose (MTD) and dose limiting toxicity (DLT) of nivolumab in combination with azacitidine (5-azacytidine) in patients with refractory/relapsed acute myeloid leukemia (AML). (Lead-in phase) II. To determine the maximum tolerated dose (MTD) and dose limiting toxicity (DLT) of nivolumab with ipilimumab in combination with 5-azacytidine in patients with refractory/relapsed acute myeloid leukemia (AML). (Lead-in phase) III. To determine the overall response rate (ORR) of nivolumab in combination with 5-azacytidine in patients with refractory/ relapsed AML. (Phase II) IV. To determine the overall response rate (ORR) of nivolumab in combination with 5-azacytidine in older patients (> 65 years) with newly diagnosed AML. (Phase II) V. To determine the overall response rate (ORR) of nivolumab with ipilimumab in combination with 5-azacytidine in patients with refractory/relapsed AML. (Phase II) VI. To determine the overall response rate (ORR) of nivolumab with ipilimumab in combination with 5- azacytidine in older patients (65 years) with newly diagnosed AML. (Phase II)

SECONDARY OBJECTIVES:

I. To determine the number of patients who achieve a > 50% reduction in blasts on therapy with either vidaza+nivolumab or vidaza+nivolumab+ipilimumab.

II. To determine the duration of response, disease-free survival (DFS), and overall survival (OS) of patients with refractory/relapsed AML treated with either vidaza+nivolumab or vidaza+nivolumab+ipilimumab.

III. To determine the duration of response, disease-free survival (DFS), and overall survival (OS) in older patients with newly diagnosed AML treated with this combination with either vidaza+nivolumab or vidaza+nivolumab+ipilimumab.

TERTIARY OBJECTIVES:

I. To study immunological and molecular changes in the peripheral blood and bone marrow in response to nivolumab and 5-azacytidine therapy or nivolumab with ipilimumab and 5-azacytidine therapy.

II. To determine induction of hypomethylation and deoxyribonucleic acid (DNA) damage during therapy with this combination and its correlation with response.

OUTLINE: This is a lead-in phase, dose-escalation study followed by a phase II study. Patients are assigned to 1 of 2 arms.

ARM I: Patients receive azacitidine intravenously (IV) over 1 hour or subcutaneously (SC) on days 1-7 or days 1-4 and 7-9. Patients also receive nivolumab IV over 60 minutes on days 1 and 14 (courses 1-4) or on day 1 (course 5 and all subsequent courses). Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

ARM II: Patients receive azacitidine and nivolumab as Arm I. Patients also receive ipilimumab IV over 90 minutes on day 1 and then every 6 or 12 weeks. Treatment continues in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days and then every 3-6 months for up to 5 years.

• ARM 2 SALVAGE COHORT: Patients with AML who have failed up to one prior salvage therapy (i.e. salvage 1 or 2 status) will be eligible for Arm 2 relapse cohort; allogeneic stem cell transplant for patients in remission at the time of stem cell transplant will not be considered a salvage regimen; similarly, hydroxyurea if used alone will not be considered a salvage regimen

• ARM 1 AND 2 FRONT LINE OLDER COHORT: Patients age 65 years and above with previously untreated AML who are unfit for or decline standard induction therapy; prior therapy with hydroxyurea, biological or targeted therapy (e.g. FLT3 inhibitors, other kinase inhibitors), or hematopoietic growth factors is allowed, however prior therapy with chemotherapy agents for the disease under study is not allowed; patients may have received one dose of cytarabine (up to 2 g/m2 administered at presentation for control) of hyperleucocytosis

• Patients with myelodysplastic syndrome (MDS) or chronic myelomonocytic leukemia (CMML) who received therapy for the MDS or CMML and progress to AML are eligible at the time of diagnosis of AML regardless any prior therapy for MDS or CMML; the World Health Organization (WHO) classification will be used for AML; prior therapy for MDS or CMML will not be considered as a prior therapy for AML, hence such patients will be considered as frontline AML and eligible for the frontline elderly cohort

• Prior therapy with hydroxyurea, chemotherapy, biological or targeted therapy (e.g. FLT3 inhibitors, other kinase inhibitors), or hematopoietic growth factors is allowed

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

• Total bilirubin =< 2 times upper limit of normal (x ULN) (=< 3 x ULN if considered to be due to leukemic involvement or Gilbert's syndrome)

• Aspartate aminotransferase or alanine aminotransferase =< 2.5 x ULN (=< 5.0 x ULN if considered to be due to leukemic involvement)

• Serum creatinine =< 2 x ULN or glomerular filtration rate (GFR) >= 50

• Patients must provide written informed consent

• In the absence of rapidly progressing disease, the interval from prior treatment to time of initiation of 5-azacytidine and nivolumab will be at least 2 weeks OR at least 5 half-lives for cytotoxic/noncytotoxic agents; the half-life for the therapy in question will be based on published pharmacokinetic literature (abstracts, manuscripts, investigator brochure's, or drug-administration manuals) and will be documented in the protocol eligibility document; since the effect of both nivolumab and 5-azacytidine may be delayed; use of one dose of cytarabine (up to 2 g/m2) or hydroxyurea for patients with rapidly proliferative disease is allowed before the start of study therapy and during the study treatment; concurrent therapy for central nervous system (CNS) prophylaxis or continuation of therapy for controlled CNS disease is permitted

• Females must be surgically or biologically sterile or postmenopausal (amenorrheic for at least 12 months) or if of childbearing potential, must have a negative serum or urine pregnancy test within 72 hours before the start of the treatment

• Women of childbearing potential must agree to use an adequate method of contraception during the study and until 3 months after the last treatment; males must be surgically or biologically sterile or agree to use an adequate method of contraception during the study until 3 months after the last treatment; adequate methods of contraception include: total abstinence when this is in line with the preferred and usual lifestyle of the patient; periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception; female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy) or tubal ligation at least six weeks before taking study treatment; in case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment; male sterilization (at least 6 months prior to screening); for female patients on the study, the vasectomized male partner should be the sole partner for that patient

• Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks ago; in the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential
