Pembrolizumab in Untreated B-Cell Non-Hodgkin Lymphoproliferative Diseases

Phase 2

Terminated

• Conditions: Indolent B-Cell Non-Hodgkin Lymphoma; Marginal Zone Lymphoma; Follicular Lymphoma
• Interventions: Other: Laboratory Biomarker Analysis; Biological: Pembrolizumab

• Registration Number: NCT03498612
• Lead Sponsor: University of Washington

Brief Summary

This phase II trial studies how well pembrolizumab works in treating patients with B-cell non-Hodgkin lymphoproliferative diseases that have not been treated. 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

OUTLINE:

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

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

• Hemoglobin >= 8 g/dL Note: Growth factor and/or transfusion support is permissible to stabilize participant prior to study treatment if needed. No lower limit if cytopenia is related to bone marrow involvement.

• Serum creatinine =< 1.5 x upper limit of normal (ULN) OR measured or calculated creatinine clearance (glomerular filtration rate [GFR] can also be used in place of creatinine or creatinine clearance [CrCl]) >= 30 mL/min for participant with creatinine levels > 1.5 x institutional ULN (GFR can also be used in place of creatinine or CrCl)

  * Creatinine clearance should be calculated per institutional standard

• Serum total bilirubin =< 1.5 x ULN OR direct bilirubin =< ULN for participants with total bilirubin levels > 1.5 x ULN

• Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT]) and alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x ULN ( =< 5 x ULN for participants with liver metastases)

• International normalized ratio (INR) or prothrombin time (PT) =< 1.5 x ULN unless participant is receiving anticoagulant therapy as long as PT or partial thromboplastin time (PTT) is within therapeutic range of intended use of anticoagulants

• Activated partial thromboplastin time (aPTT) =< 1.5 x ULN unless participant is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants

• Female subject of childbearing potential should have a negative urine or serum pregnancy within 72 hours 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; subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year

• 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

• Is currently participating and receiving study therapy or has participated in a study of an investigational agent 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

Count of Participants Who Experience Adverse Events (AEs)	Up to 90 days after last dose, up to 1 year.	Safety summaries will include tabulations in the form of tables. The frequency of treatment-emergent AE's will be summarized. Additional AE summaries will include AE frequency by AE severity and relationship to the study drug.
