B Acute Lymphoblastic Leukemia, Minimal Residual Disease, Recurrent Acute Lymphoblastic Leukemia, T Acute Lymphoblastic Leukemia
Conditions
Brief summary
This phase II trial studies how well pembrolizumab works in treating small amounts of cancer cells that remain after attempts to remove the cancer has been made in patients with acute lymphoblastic leukemia. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.
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.

Exclusion criteria
* Is currently participating and receiving study therapy or has participated in a study of an investigational new drug and received study therapy or used an investigational device within 4 weeks of the first dose of treatment * Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment * Has a known history of active bacillus tuberculosis (TB) * Has a known hypersensitivity to pembrolizumab or any of its excipients * Has had a prior anti-cancer monoclonal antibody (mAb) within 4 weeks prior to study day 1 or who has not recovered (i.e., =\< grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier * Has had prior chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to study day 1 or who has not recovered (i.e., =\< grade 1 or at baseline) from adverse events due to a previously administered agent * Note: subjects with =\< grade 2 neuropathy or with hematologic toxicity that has recovered to levels above that stated in inclusion criterion are an exception to this criterion and may qualify for the study if all other inclusion/
