Has major surgery within 2 weeks of study entry.~8. Receipt of any conventional chemotherapy or radiation therapy (RT) within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to study treatment or planned use during the course of the study.~9. Receipt of corticosteroids within 7 days of study treatment, unless subject has been taking a continuous systemic dose of no more than 10 mg/day or equivalent dose of prednisone, or a local or inhaled or intranasal administration at fixed doses for at least 1 month prior to study treatment and tumor shrinkage was not observed.~10. Use of any investigational drugs, biologics, or devices within 4 weeks prior to study treatment or planned use during the course of the study.~11. Receipt of anti-tumor antibody therapy within 100 days prior to study treatment.~12. History of allogeneic hematopoietic stem cell transplantation. Or subjects with a history of autologous hematopoietic stem cell transplantation within 100 days prior to study treatment.~13. Previous exposure to pralatrexate.~14.
