About this study

Official title: 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

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.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To evaluate the efficacy of pembrolizumab in minimal residual disease (MRD)-positive acute lymphoblastic leukemia (ALL).

SECONDARY OBJECTIVES:

  1. 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:

  1. 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.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Laboratory Biomarker Analysis and Pembrolizumab in people with B Acute Lymphoblastic Leukemia and Minimal Residual Disease, run by University of Washington at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 21 inclusion and 28 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 20 Aug 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 11 Aug 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Rate of Complete Minimal Residual Disease Response (time frame: Up to 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02767934, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Aug 2020.
