Pembrolizumab in Treating Minimal Residual Disease in Patients With Acute Lymphoblastic Leukemia
A Phase II Study of Anti-PD-1 Antibody (MK-3475; Pembrolizumab) for the Treatment of Minimal Residual Disease in Adults With Acute Lymphoblastic Leukemia

Intervention / Treatment
Detailed Description
PRIMARY OBJECTIVES:
I. To evaluate the efficacy of pembrolizumab in minimal residual disease (MRD)-positive acute lymphoblastic leukemia (ALL).
SECONDARY OBJECTIVES:
I. To describe the toxicity profile of pembrolizumab in patients with previously-treated ALL.
II. To gain a preliminary assessment of how MRD response translates into relapse-free and overall survival.
EXPLORATORY OBJECTIVES:
I. To compare disease assessments by multiparameter flow cytometry (MFC) and polymerase chain reaction (PCR) to a newly-developed and more sensitive next generation sequencing (NGS)-based platform.
II. To correlate response to pembrolizumab to immunologic markers in peripheral blood and bone marrow specimens.
III. To evaluate if treatment with pembrolizumab has a measurable impact on hematopoietic engraftment and graft-vs-host disease (GVHD) in patients who subsequently undergo allogeneic hematopoietic cell transplantation (HCT).
OUTLINE:
Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1. Cycles repeat every 21 days for 2 years in the absence of disease progression or unacceptable toxicity. Patients achieving complete MRD response may receive up to 1 additional year of treatment at the discretion of the investigator.
After completion of study treatment, patients are followed up every 3 months for up to 2 years.

- Be willing and able to provide written informed consent for the trial
Presence of MRD (defined as < 5% blasts in the bone marrow by morphologic assessment and no clinically-apparent extramedullary disease but with quantifiably-measurable disease as assessed by either MFC or PCR) under any of the following circumstances:
- MRD persistence >= 11 weeks after the start of initial therapy
- MRD persistence >= 2 weeks after the start of salvage therapy, or
- MRD reappearance at any time
- For patients with Philadelphia chromosome positive (Ph+) disease, have previously received treatment with >= 1 Abelson (ABL) kinase inhibitor (e.g., imatinib, dasatinib, etc.) or are ineligible for such treatment

- Be willing to provide tissue from a newly obtained bone marrow aspirate and/or biopsy; newly-obtained is defined as a specimen obtained up to 28 days prior to initiation of treatment on day 1; subjects for whom newly-obtained samples cannot be provided (e.g., inaccessible or subject safety concern) may submit an archived specimen only upon agreement from the principal investigator (PI)
- Have a performance status of 0 to 1 on the Eastern Cooperative Oncology Group (ECOG) performance scale

- Hemoglobin >= 8 g/dL (performed within 10 days of treatment initiation)
- Platelets >= 50,000 /mcL (performed within 10 days of treatment initiation)
- Serum creatinine =< 1.5 X upper limit of normal (ULN) OR measured or calculated creatinine clearance >= 60 mL/min/1.73 m^2 for subject with creatinine levels > 1.5 X institutional ULN (performed within 10 days of treatment initiation) (glomerular filtration rate [GFR] can also be used in place of creatinine or creatinine clearance [CrCl])

- International normalized ratio (INR) or prothrombin time (PT) =< 1.5 ULN unless subject is receiving anticoagulant therapy as long as PT or partial thromboplastin time (PTT) is within therapeutic range of intended use of anticoagulants (performed within 10 days of treatment initiation)
- Activated partial thromboplastin time (aPTT) =< 1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants (performed within 10 days of treatment initiation)
- Female subjects of childbearing potential should have a negative urine or serum pregnancy within 3 days prior to receiving the first dose of study medication; if the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
- Female subjects of childbearing potential should be willing to use 2 methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study through 120 days after the last dose of study medication
- Male subjects should agree to use an adequate method of contraception starting with the first dose of study therapy through 120 days after the last dose of study therapy
Exclusion Criteria:
