A Phase 1/2a Open-label Study of Pralatrexate and Gemcitabine With Vitamin B12 and Folic Acid Supplementation in Patients With Relapsed or Refractory Lymphoproliferative Malignancies

This study is for patients with lymphoproliferative malignancies that have progressed after receiving a previous treatment (relapsed) or are no longer responding to treatment (refractory). To be in this study, patients must have certain types of Hodgkin's lymphoma (HL), peripheral T-cell lymphoma (PTCL), or B-cell lymphoma, including Waldenstrom's macroglobulinemia. This study is being done to find doses of the combination of pralatrexate and gemcitabine with vitamin B12 and folic acid that can be safely given to patients with these types of lymphoma and explore the effectiveness of the treatment.

Stanford is not currently accepting new patients for this trial. You may want to check to see if other locations are recruiting.

- Phase 1: Histologically/cytologically confirmed lymphoproliferative malignancy. Patients with Hodgkin lymphoma (HL) or non-HL are eligible, with exceptions per exclusion criteria. - Phase 2a: Histologically/cytologically confirmed HL, peripheral T-cell lymphoma (PTCL), or B-cell lymphoma including Waldenström's macroglobulinemia, with exceptions per exclusion criteria. - Progression of disease (PD) after at least 1 prior treatment (any number of prior therapies allowed). PD after last prior treatment and recovered from toxic effects of prior therapy.
