Participants received pralatrexate at an initial dose of 30 mg/m\^2, as IV push over 30 seconds to 5 minutes via a patent free-flowing IV line containing normal saline on Days 1, 8 and 15 of a 4-week cycle (weekly for 3 weeks with 1 week of rest) until criteria for discontinuation per protocol were met. The initial dose of 30 mg/m\^2 may be reduced to 20 mg/m\^2 weekly, permitted per protocol defined criteria. If pralatrexate 20 mg/m\^2/week was not tolerated, pralatrexate had to be discontinued. Dose re-escalation was not allowed once dose reduction was done.

Participants had dietary supplement of vitamin B12 and folic acid along with pralatrexate. Vitamin B12, given as 1mg IM, within 10 weeks of start of pralatrexate dosing, every 8-10 weeks throughout the study and for at least 30 days post last dose of pralatrexate. Folic acid was given 1mg daily, orally, for at least 7 days prior to start of pralatrexate, throughout the study and for at least 30 days post last dose of pralatrexate.

Pralatrexate

The purpose of this study is to determine whether pralatrexate, given with vitamin B12 and folic acid, is effective in the treatment of relapsed or refractory B-cell Non-Hodgkin's lymphoma (NHL). The study will also investigate the safety of pralatrexate with vitamin B12 and folic acid in this participant population. Additionally, this study includes the collection of blood samples to investigate the pharmacokinetics (PK) of pralatrexate in this participant population (PK is the activity of a drug in the body over a period of time, including how the drug is absorbed, distributed in the body, localized in the tissues, and excreted from the body).

Study of Pralatrexate to Treat Participants With Relapsed or Refractory B-cell Non-Hodgkin's Lymphoma

A Phase 2, Single-arm, Open-label, Multi-center Study of Pralatrexate in Patients With Relapsed or Refractory B-cell Non-Hodgkin's Lymphoma

Objective response rate was defined as the percentage of participants with a complete response (CR) or a partial response (PR). Tumor response was evaluated on the basis of clinical and radiological criteria, assessed according to International Workshop Criteria (IWC) with or without positron emission tomography (PET) scans. Per IWC criteria CR is defined as complete disappearance of all detectable clinical and radiographic evidence of disease and disappearance of all disease-related symptoms if present before therapy, and normalization of those biochemical abnormalities definitely assignable to non-Hodgkin's lymphoma (NHL) and PR is defined as \>= 50% decrease in sum of the product of the perpendicular diameters (SPD) of the six largest dominant nodes or nodal masses and no increase in size of other nodes, liver or spleen.

The Duration of Response was defined as the time (in months) from the date the measurement criteria were first met for CR or PR (whichever status was recorded first) until the first subsequent date that relapse or progression was documented. It was assessed according to IWC with or without PET, subject to its availability. Per IWC, progression was defined as a ≥50% increase from the nadir in the individual sum of the products of the diameters of any index lesion; the reappearance of pathology, enlargement of liver/spleen, or unequivocal progression of non-measurable disease or appearance of any new lesions.

Progression-free survival (PFS) was the duration of time (in months) from first administration of study treatment to date of first documented progression or death from any cause. It was based on tumor assessments made according to the IWC with or without PET scans, subject to their availability. Per IWC, progression was defined as a ≥50% increase from the nadir in the individual sum of the products of the diameters of any index lesion; the reappearance of pathology, enlargement of liver/spleen, or unequivocal progression of non-measurable disease or appearance of any new lesions.

Overall Survival was the time (in months) from first administration of study treatment until the date of death.
