Brief summary

This phase 2 trial studies the effect of intravenous (IV) vitamin C repletion after myeloablative allogeneic stem cell transplant.

Detailed description

Vitamin C is a nutritional supplement that can help fight inflammation. Most patients who have a stem cell transplant have lower than normal levels of vitamin C in their blood. Patients will receive intravenous Vitamin C the day after transplant for two weeks, followed by oral vitamin C until six months after transplant. The effect of the Vitamin C on non-relapse mortality (NRM), time to engraftment, rate of acute graft-versus-host disease and to characterize the safety and tolerability of the vitamin C regimen.

Interventions

DRUGIntravenous (IV) and oral Vitamin C

Intravenous (IV) vitamin C 50 mg/kg/day divided in 3 doses beginning on posttransplant Day +1 and continuing through Day +14; each dose (16.7 mg/kg) given in 50 mL of 5% dextrose and water over 30 minutes every 8 hours • After completion of the IV vitamin C doses, oral vitamin C 500 mg twice each day beginning on Day +15 and continuing until Day +180

Participants by arm

ArmCount
IV Vitamin C Followed by Oral Vitamin C
All study participants will receive the same treatment. Each participant will be given intravenous, which means by vein (IV), vitamin C three times a day for 14 days. Then participants will take vitamin C orally (by mouth in pill form) twice a day each day until 6 months after transplant. The treatment is IV vitamin C 50 mg/kg/day. After completion of the IV vitamin C doses, oral vitamin C 500 mg twice each day. Intravenous (IV) and oral Vitamin C: Intravenous (IV) vitamin C 50 mg/kg/day divided in 3 doses beginning on posttransplant Day +1 and continuing through Day +14; each dose (16.7 mg/kg) given in 50 mL of 5% dextrose and water over 30 minutes every 8 hours • After completion of the IV vitamin C doses, oral vitamin C 500 mg twice each day beginning on Day +15 and continuing until Day +180
