A Phase 1 Study of Blinatumomab in Combination With Checkpoint Inhibitor(s) of PD-1 (Nivolumab) or Both PD-1 (Nivolumab) and CTLA-4 (Ipilimumab) in Patients With Poor-Risk, Relapsed or Refractory CD19+ Precursor B-Lymphoblastic Leukemia

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 or has
not responded to treatment. 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.


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 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 acute lymphoblastic leukemia (ALL) or CD19+ mixed phenotype acute leukemia (MPAL).


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 an expansion cohort of patients with
poor-risk, relapsed or refractory CD19+ precursor B-lymphoblastic leukemia, or CD19+ mixed
phenotype acute leukemia (MPAL).


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 60 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

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

surface antigen (HBsAg), hepatitis B core antibody (anti-HBc) in the absence of
hepatitis B surface antibody (anti-HBs), or a positive hepatitis C (HCV) viral load;
these patients are excluded due to the risk for autoimmune hepatitis with immune
checkpoint inhibitors exacerbating their known liver disease as well as the unknown
risk for hepatitis B and/or C reactivation with blinatumomab and immune checkpoint

Crohn's, ulcerative colitis, hepatitis; and patients with a history of toxic
epidermal necrolysis (TEN), Stevens-Johnson syndrome, or phospholipid syndrome
should be excluded because of the risk of recurrence or exacerbation of disease

- Patients should be excluded if they have a condition requiring systemic treatment with
either corticosteroids (> 10 mg daily prednisone equivalents) or other
immunosuppressive medications within 14 days of study drug administration; inhaled or
topical steroids and adrenal replacement doses =< 10 mg daily prednisone equivalents
are permitted in the absence of active autoimmune disease; patients are permitted to
use topical, ocular, intra-articular, intranasal, and inhalational corticosteroids
(with minimal systemic absorption); physiologic replacement doses of systemic
corticosteroids are permitted, even if > 10 mg/day prednisone equivalents; a brief
course of corticosteroids for prophylaxis (e.g., contrast dye allergy) or for
treatment of non-autoimmune conditions (e.g., delayed-type hypersensitivity reaction
caused by contact allergen), or as pre-phase treatment for cytoreduction; patients
will receive steroids with blinatumomab to reduce cytokine release syndrome (CRS) as
specified in the protocol
