About this study
Official title: Comparison of Pharmocokinetics of Mycophenolate Mofetil and Enteric Coated Mycophenolate Sodium in Calcineurininhibitor-free Treated Patients After Renal Transplantation
This open-label, 2-arm study will compare the pharmacokinetics of CellCept and mycophenolate sodium in kidney transplanted patients on a calcineurininhibitor-free mycophenolic acid-based therapy. On the study day patients will take their prescribed medication (either CellCept or mycophenolate sodium). Blood samples will be drawn directly before and at intervals up to 12 hours after intake of the study medication. Anticipated time on study treatment is 12 hours and target sample size is 24.

| Study group | Role | What they receive |
|---|---|---|
| MMF, Prednisone | Experimental | Participants received mycophenolate mofetil (MMF) orally (PO) at a dose of 1 gram per day (g/day) twice daily (BID), and prednisone, PO, up to 5 milligrams per day (mg/day) for at least 1 month. Receives: Drug: MMF; Drug: Prednisone |
| EC-MPS | Active comparator | Participants received mycophenolate sodium (EC-MPS), PO, at a dose of 720 mg/day BID, and prednisone PO up to 5 mg/day for at least 1 month. Receives: Drug: EC-MPS; Drug: Prednisone |
What is being measured
The primary outcome is the main question the study is designed to answer.
Pre-dose Trough Concentration (C0)
The mean mycophenolic acid (MPA) concentration in plasma was determined (in milligrams per liter [mg/L]) from blood samples collected predose (immediately before receiving study treatment).
Measured: Day 1 predose
Dose-Normalized C0
Dose normalized C0 was determined (in mg/L) from blood samples collected predose. Both MMF and EC-MPS doses were normalized to a standard dose of 1 g MMF or 720 mg EC-MPS, respectively. The dose normalization was calculated as follows:
For the MMF group: Dose normalized C0 equals (=) C0 divided by (/) (actual dose taken/1000) For the EC-MPS group: Dose normalized C0 = C0 / (actual dose taken/720)
Measured: Day 1 predose
Minimum Plasma Concentration (Cmin)
The mean minimum MPA concentration in plasma was determined (in mg/L) from blood samples collected predose and postdose on Day 1.
Measured: Day 1 predose and postdose at 30 and 60 minutes and 2, 3, 4, 5, 6, 8 10 and 12 hours
Dose-Normalized Cmin
Dose-normalized Cmin was determined (in mg/L) from blood samples collected predose and postdose. Both MMF and EC-MPS doses were normalized to a standard dose of 1 g MMF or 720 mg EC-MPS, respectively. The dose normalization was calculated as follows:
For the MMF group: Dose normalized Cmin = Cmin/ (actual dose taken/1000) For the EC-MPS group: Dose normalized Cmin = Cmin / (actual dose taken/720)
Measured: Day 1 predose and postdose at 30 and 60 minutes and 2, 3, 4, 5, 6, 8 10 and 12 hours
Maximum Plasma Concentration (Cmax)
The mean maximum MPA concentration in plasma was determined (in mg/L) in blood samples collected predose and postdose on Day 1.
Measured: Day 1 predose and postdose at 30 and 60 minutes and 2, 3, 4, 5, 6, 8 10 and 12 hours
Dose-Normalized Cmax (mg/L)
Dose-normalized Cmax in plasma was determined (in mg/L) from blood samples collected predose and postdose on Day 1. Both MMF and EC-MPS doses were normalized to a standard dose of 1 g MMF or 720 mg EC-MPS, respectively. The dose normalization was calculated as follows:
For the MMF group: Dose normalized Cmax = Cmax / (actual dose taken/1000) For the EC-MPS group: Dose normalized Cmax = Cmax / (actual dose taken/720)
Measured: Day 1 predose and postdose at 30 and 60 minutes and 2, 3, 4, 5, 6, 8 10 and 12 hours
MPA Area Under the Curve From 0 to 12 Hours (AUC0-12)
The mean MPA AUC0-12 in plasma was determined (in mg multiplied by hours, per Liter [mg*h/L]) from blood samples collected predose and postdose on Day 1.
Measured: Day 1 predose and postdose at 30 and 60 minutes and 2, 3, 4, 5, 6, 8 10 and 12 hours
Dose-Normalized MPA AUC0-12
Dose-normalized MPA AUC0-12 in plasma was determined (mg*h/L) from blood samples collected predose and postdose on Day 1. Both MMF and EC-MPS doses were normalized to a standard dose of 1 g MMF or 720 mg EC-MPS, respectively. The dose normalization was calculated as follows:
For the MMF group: Dose normalized MPA AUC = MPA AUC / (actual dose taken/1000) For the EC-MPS group: Dose normalized MPA AUC = MPA AUC / (actual dose taken/720)
Measured: Day 1 predose and postdose at 30 and 60 minutes and 2, 3, 4, 5, 6, 8 10 and 12 hours
Percentage of Participants By Time to Maximum Plasma Concentration (Tmax)
Measured: Day 1 predose and postdose at 30 and 60 minutes and 2, 3, 4, 5, 6, 8 10 and 12 hours

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing MMF, EC-MPS and Prednisone in people with Kidney Transplantation, run by Hoffmann-La Roche at 1 site in Germany.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 27 Aug 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 10 Oct 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Pre-dose Trough Concentration (C0) (time frame: Day 1 predose). The study lists 9 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Aug 2015.
