Study to Compare the Pharmacokinetics of Tacrolimus in Stable Pediatric Allograft Recipients Converted From Prograf® to Advagraf®

Kidney Transplantation Clinical Trial

Official title:
A Phase II, Open-Label, Multi-Center Study to Compare the Pharmacokinetics of Tacrolimus in Stable Pediatric Allograft Recipients Converted From a Prograf® Based Immunosuppressive Regimen to a Tacrolimus Prolonged Release, Advagraf® Based Immunosuppressive Regimen, Including a Long-Term Follow-Up

Status Active, not recruiting

Clinical Trial Summary

Parts A & B: Conversion of stable pediatric allograft recipients from Prograf® immunosuppression to Advagraf® immunosuppression to compare exposure and one year follow-up for safety and efficacy. Part C: Continuation of long-term follow-up and provision of ongoing study medication to subjects to whom Advagraf® is currently not available.

Clinical Trial Description

Part A: On Day 1 subjects will be converted from their routine Prograf®-based immunosuppressive regimen to a Prograf®-based immunosuppressive regimen supplied by the Sponsor as study medication and continue treatment until Day 7. The daily dose of the study medication must be the same [1:1 (mg:mg)] as the Prograf® dose received during the 30-day screening period. On Day 7 the first 24 hour PK profile will be started. Samples will be taken over a 24 hour period and will be completed on Day 8. On Day 8 subjects will be switched to once-daily Advagraf® on a 1:1 (mg:mg) total daily dose basis and continue treatment until Day 14. On Day 14 the second 24-hour PK profile will be started. Samples will be taken over a 24-hour period and will be completed on Day 15. Part B: One year follow-up period to evaluate safety and efficacy of tacrolimus when administered as an Advagraf®-based immunosuppressive regimen. Part C: Continuation of long-term follow-up (from Day 365 onwards). Patients who have completed Part B and to whom continued treatment with Advagraf® is not currently available, will be offered participation in a continuation of long-term follow-up (Part C). Part C will continue until Advagraf® becomes available to these patients or these patients' discontinuation, whichever is the earliest. Part C applies to patients in the following countries: United Kingdom, Czech Republic, Germany, Italy, and Poland only. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
