Brief Summary

This phase II trial studies how well pembrolizumab works in treating participants with B-cell
non-Hodgkin lymphoproliferative diseases that have not been treated. Monoclonal antibodies,
such as pembrolizumab, may interfere with the ability of cancer cells to grow and spread.

Detailed Description


I. To gain a preliminary assessment of the efficacy of pembrolizumab as monotherapy for
patients with untreated indolent B-cell non-Hodgkin lymphoproliferative diseases (iBCL) based
on overall response rate (ORR) measured at the end of a 6-cycle treatment period.


I. To assess the safety and toxicity profile of pembrolizumab in patients with untreated

II. To measure the efficacy of pembrolizumab used as monotherapy for patients with untreated
iBCL by assessing clinical outcomes including complete response rate (CR), time to next
therapy (TNT), progression-free survival (PFS), and the duration of response (DOR).


Participants receive pembrolizumab intravenously (IV) over 30 minutes on day 1. Treatment
repeats every 3 weeks for up to 18 courses in the absence of disease progression or
unacceptable toxicity.

After completion of study treatment, participants are followed up for 30 days and then up to
5 years.

Conditions usually refer to a disease, disorder, syndrome, illness, or injury. In, conditions include any health issue worth studying, such as lifespan, quality of life, health risks, etc.

Interventions refer to the drug, vaccine, procedure, device, or other potential treatment being studied. Interventions can also include less intrusive possibilities such as surveys, education, and interviews.
Study Phase

Most clinical trials are designated as phase 1, 2, 3, or 4, based on the type of questions that study is seeking to answer:

In Phase 1 (Phase I) clinical trials, researchers test a new drug or treatment in a small group of people (20-80) for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.

In Phase 2 (Phase II) clinical trials, the study drug or treatment is given to a larger group of people (100-300) to see if it is effective and to further evaluate its safety.

In Phase 3 (Phase III) clinical trials, the study drug or treatment is given to large groups of people (1,000-3,000) to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.

In Phase 4 (Phase IV) clinical trials, post marketing studies delineate additional information including the drug's risks, benefits, and optimal use.

These phases are defined by the Food and Drug Administration in the Code of Federal Regulations.
