Pembrolizumab in Untreated B-Cell Non-Hodgkin Lymphoproliferative Diseases
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.
|Condition or Disease||Intervention/Treatment||Phase|
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.
Arms and Interventions
|Experimental: Treatment (pembrolizumab)
Patients receive pembrolizumab 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.
Other: Laboratory Biomarker Analysis
Primary Outcome Measures
- Overall response rate (complete response [CR] + partial response [PR] for follicular lymphoma and marginal zone lymphoma) [Up to 5 years]
Measured by Lugano Criteria evaluated by positron emission tomography (PET)/computed tomography (CT) or CT or white blood cell count for chronic lymphocytic leukemia (CLL). The corresponding 95% two-sided confidence interval will be derived.
Secondary Outcome Measures
- Duration of response [From the time by which the measurement criteria are met for CR or PR, whichever is recorded first, until death or the first date by which recurrent or progressive disease is objectively documented, assessed up to 5 years]
Kaplan Meier methodology will be used to estimate event-free curves.
- Progression-free survival [From the first study drug administration to the first occurrence of lymphoma progression or death from any cause, assessed up to 5 years]
Data for subjects without disease progression or death will be censored at the date of the last tumor assessment. Kaplan-Meier methodology will be used to estimate the event-free curves.
- Time to next therapy [From the time of first study drug administration until the date of the first subsequent therapy given to treat the indolent B-cell non-Hodgkin lymphoproliferative diseases, assessed up to 5 years]
- Incidence of adverse events (AEs) [Up to 30 days after last dose]
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.
Be willing and able to provide written informed consent/assent for the trial
Must have measurable disease defined by at least one of the following criteria:
- Lesions greater than 1.5 cm that can be accurately measured in two dimensions by computed tomography (CT) (preferred), or magnetic resonance imaging (MRI)
- Must have indication for treatment (adapted from National Comprehensive Cancer Network [NCCN] 2015 guidelines)
- Any of the following constitute an indication for treatment:
Significant symptoms due to any iBCL: Which may include pain/discomfort, limitation of function, fatigue/malaise/constitutional symptoms, B-symptoms (fever, weight loss, night sweats), pruritus
Threatened end-organ function due to any iBCL
Progressive cytopenia secondary to any iBCL
Steady progression of follicular lymphoma (FL) and marginal zone lymphoma (MZL)
Have a performance status of 0 or 1 on the Eastern Cooperative Oncology Group (ECOG) performance scale
Absolute neutrophil count (ANC) >= 500/uL 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.
Platelets >= 25000/uL 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.
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
