Summary

This phase I trial studies the side effects and best dose of blinatumomab when given with nivolumab alone or nivolumab and ipilimumab in treating patients with poor-risk CD19+ precursor B-lymphoblastic leukemia that has come back after a period of improvement (relapsed) or has not responded to treatment (refractory). Immunotherapy with monoclonal antibodies, such as blinatumomab, nivolumab, and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Description

PRIMARY OBJECTIVES:

I. To evaluate the safety and tolerability of the blinatumomab given in combination with nivolumab alone, or in combination with both nivolumab and ipilimumab in subjects with poor-risk, relapsed or refractory CD19+ pre-B cell acute lymphoblastic leukemia (ALL) or CD19+ mixed phenotype acute leukemia (MPAL).

II. To determine the maximum tolerated dose (MTD) of the combination of blinatumomab plus nivolumab, and blinatumomab plus both nivolumab and ipilimumab and to further confirm the safety of the combination therapy in subjects with poor-risk, relapsed or refractory CD19+ pre-B cell ALL or CD19+ mixed phenotype acute leukemia (MPAL).

SECONDARY OBJECTIVES:

I. To observe and record anti-leukemia activity of blinatumomab and nivolumab, and blinatumomab plus both nivolumab and ipilimumab, including the effects on minimal residual disease (MRD).

II. To assess preliminary anti-leukemia activity in expansion cohorts of patients with poor-risk, relapsed or refractory CD19+ precursor B-lymphoblastic leukemia, or CD19+ mixed phenotype acute leukemia (MPAL).

EXPLORATORY OBJECTIVES:

I. To examine changes in absolute lymphocyte count and distribution of T cell subsets (CD4+, CD8+, regulatory T cells [Tregs], effector T cells [Teffs]) and their differentiation status, natural killer (NK) cells, and B cells before and post-blinatumomab, and immune checkpoint inhibitor(s) therapy in both peripheral blood and the bone marrow microenvironment.

II. To explore changes in T cell co-signaling receptors expression in defined T cell subpopulations and their canonic transcription factor expression in both peripheral blood and bone marrow before and post-blinatumomab, and immune checkpoint inhibitor(s) therapy.

III. To examine changes in expression of co-signaling molecules on leukemia blasts (CD10+/CD19+/CD34+) before and after treatment with blinatumomab and checkpoint inhibitors.

IV. To examine the serum levels of cytokines before and after treatment with blinatumomab and checkpoint inhibitors, including the levels of sCTLA-4.

V. To perform immune profiling of T cell repertoire and characterize T cell transcriptional signature before and after treatment.

OUTLINE: This is a dose-escalation study of blinatumomab.

Patients receive blinatumomab intravenously (IV) continuously on days 1-28. Treatment repeats every 42 days for up to 5 cycles in the absence of disease progression or unacceptable toxicity. Patients also receive nivolumab IV over 30 minutes on day 11 and then every 2 weeks for up to year. Some patients also receive ipilimumab IV over 90 minutes on day 11 and then every 6 weeks for up to 1 year.

After completion of study treatment, patients are followed up every 3 months for up to 2 years.

Exclusion Criteria

Patients who have had chemotherapy or other systemic therapy or radiotherapy, or those who have not recovered from adverse events due to prior administered agents as follows: chemotherapy, radiotherapy or surgery =< 3 weeks prior to entering the study, targeted therapy (e.g., TKI) =< 1 week prior to entering the study; autologous HSCT =< 6 weeks prior to entering the study; investigational drug or immunotherapy (e.g. rituximab) =< 4 weeks prior to entering the study; prophylactic intrathecal chemotherapy within one week of enrollment allowed; patients will be allowed to receive cytoreduction with hydroxyurea, 6-mercaptopurine, corticosteroids (dexamethasone, prednisone or similar) or cyclophosphamide provided that it is discontinued at least 24 hours prior to the initiation of study treatment; pre-phase treatment with dexamethasone 10 mg/m^2 (maximum total 24 mg per day) for up to 5 days is required for patients with bone marrow blasts more than 50%, peripheral blood blasts of 15,000/uL or higher, or elevated lactate dehydrogenase suggesting rapidly progressing disease as per investigator's assessment; pre-phase treatment must be stopped at least 24 hours prior to the initiation of blinatumomab
Patients who are receiving any other investigational agents
Patients should be excluded if they have had prior treatment with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CTLA-4 antibody, or any other antibody or drug specifically targeting T-cell co-stimulation or immune checkpoint pathways
Patients with active central nervous system leukemia are excluded from this clinical trial because they may develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events; patients with a history of central nervous system (CNS) leukemia but no active disease at the time of enrollment are eligible; the absence of CNS disease must be confirmed by flow cytometric and cytologic examination of the cerebrospinal fluid (CSF) within 7 days of study enrollment

History of severe hypersensitivity reaction to any monoclonal antibody
Uncontrolled intercurrent illness including, but not limited to, active, uncontrolled infection; symptomatic congestive heart failure; unstable angina pectoris; cardiac arrhythmia; or psychiatric illness/social situations that would limit compliance with study requirements; patients with infection under treatment and controlled with antibiotics are eligible
Pregnant women are excluded from this study because nivolumab and ipilimumab have the potential for teratogenic or abortifacient effects; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with nivolumab and ipilimumab, breastfeeding should be discontinued if the mother is treated with nivolumab and ipilimumab; these potential risks may also apply to blinatumomab

Patients who have had evidence of active or acute diverticulitis, intra-abdominal abscess, gastrointestinal (GI) obstruction and abdominal carcinomatosis which are known risk factors for bowel perforation should be evaluated for the potential need for additional treatment before coming on study
Patients who have a history of clinically relevant CNS pathology such as epilepsy, seizure, paresis, aphasia, stroke, severe brain injuries, dementia, Parkinson's disease, cerebellar disease, psychosis, or other significant CNS abnormalities; a history of treated CNS leukemia will be allowed if recent CNS studies confirm the absence of active CNS disease at the time of study entry (screening)
