Clinical Trial Summary

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).

Eligibility

Inclusion Criteria:

• Histologically/cytologically confirmed, measurable (lesion or node =2 cm by CT [at least 1 cm if by spiral CT]) B-cell Non-Hodgkin's Lymphoma, using the Revised European American Lymphoma (REAL) World Health Organization (WHO) disease classification

• Adequate blood, liver, and kidney functions as defined by laboratory levels

• 1.0 mg/day orally of folic acid for at least 7 days prior & 1 mg intramuscular of vitamin B12 within 10 weeks of the planned start of pralatrexate

• Females of childbearing potential must agree to use medically acceptable birth control from start of pralatrexate until at least 30 days after the last administration of pralatrexate and must have a negative serum pregnancy test within 14 days prior to the first day of study treatment

• Males who are not surgically sterile must agree to use medically acceptable birth control from start of pralatrexate until at least 90 days after the last administration of pralatrexate

• Available for repeat dosing and follow-up

• Able to give written informed consent

Exclusion Criteria:

• Relapsed participants with diffuse large B-cell lymphoma (DLBCL) who are candidates for high-dose therapy and autologous stem cell transplantation (SCT) and for whom high-dose therapy and autologous SCT is a standard curative option

• Active concurrent malignancy (except non-melanoma skin cancer or carcinoma in situ of the cervix). If there is a history of prior malignancies other than those exceptions listed above, the participant must be disease-free for = 5 years. Participants with other prior malignancies < 5 years before study entry may still be enrolled if they have received treatment resulting in complete resolution of the cancer and currently have no clinical, radiologic, or laboratory evidence of active or recurrent disease

• Congestive heart failure Class III/IV according to the New York Heart Association Functional Classification

• Uncontrolled hypertension

• Known human immunodeficiency virus (HIV)-positive diagnosis

• Symptomatic central nervous system (CNS) metastases or lesions for which treatment is required. Participants who received prophylactic CNS treatment are eligible.

• Participants who have undergone an allogeneic SCT

• Participants who have relapsed < 100 days from the time of an autologous SCT

• Participants with disease refractory to peripheral blood SCT or who have relapsed < 100 days from the time of transplant

• Active uncontrolled infection, underlying medical condition, or other serious illness that would impair the ability of the participant to receive protocol treatment.

• Major surgery within 14 days of enrollment

• Receipt of any conventional chemotherapy or radiation therapy (encompassing a substantial [> 10%] amount of bone marrow) within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to study treatment or planned use during the course of the study

• Receipt of systemic corticosteroids within 1 week of study treatment, unless participant has been taking a continuous dose of no more than 10 mg/day of prednisone or its equivalent for at least 1 month

• Use of any investigational drugs, biologics, or devices within 4 weeks prior to study treatment or planned use during the course of the study

• Previous exposure to pralatrexate

• Females who are pregnant or breastfeeding

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Objective Response Rate (ORR)	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.	Up to 24 months
Secondary	Duration of Response (DOR)	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.	Up to 24 months
Secondary	Progression Free Survival (PFS)	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.	Up to 24 months
Secondary	Overall Survival (OS)	Overall Survival was the time (in months) from first administration of study treatment until the date of death.	Up to 24 months
