Unscheduled radiological response assessments will be performed earlier if clinical progression is suspected.The primary analysis will be conducted once all subjects have completed cycle 5 treatment or discontinued before. Study treatment may continue per investigator judgment for a maximum of 24 months.\n\nResponse will be assessed on the basis of clinical, radiological, and pathological criteria. Response will be assessed by independent central review and by the treating investigator. Central review assessors will be blinded to the response assessments by the treating investigator. The primary analysis will be based on response assessed by central review.","groups":[{"description":"Vitamin B12 and folic acid will be taken concurrently with pralatrexate\n\npralatrexate: Pralatrexate will be administered at a dose of 30 mg/m2/week for 6 weeks followed by 1 week of rest in a 7-week cycle. Pralatrexate administration occurs once a week during week 1 through week 6 of each cycle.\n\nVitamin B12 and folic acid: The eligible subjects will receive vitamin supplementation at screening phase, at least 10 days prior to pralatrexate administration on cycle 1, dose 1. Vitamin supplementation will consist of vitamin B12 1 mg intramuscular (IM) q 8-10 weeks and folic acid 1.2mg by mouth (PO) once a day (QD). Once pralatrexate is permanently discontinued, vitamin supplementation should continue at least 1 month after the last pralatrexate dose, or longer at the discretion of the investigator.","id":"OG000","title":"Pralatrexate"}],"paramType":"COUNT_OF_PARTICIPANTS","populationDescription":"The primary analysis was based on the independent review data using the safety population, safety population is 71 for this study","reportingStatus":"POSTED","timeFrame":"2 years","title":"Objective Response Rate(ORR) by International Working Group Criteria","type":"PRIMARY","unitOfMeasure":"Participants"}
