A Study Designed to Compare the Tolerability of an Increased Dose of Enteric-coated Mycophenolate Acid (MPA) in Renal Transplant Patients Whose Dose of Mycophenolate Mofetil (MMF) Was Reduced Due to Gastrointestinal Symptoms

A Multicenter, Randomized, Double Blind, Double Dummy Controlled Study to Assess the Tolerability of an Increased Dose of Enteric Coated MPA After Conversion From MMF in Renal Transplant Recipients Who Required MMF Dose Reductions Due to Gastrointestinal Symptoms

Inclusion criteria

* Recipients of first or second cadaveric, living unrelated or living related kidney transplant. * Patients on a reduced daily dose (500mg to 1500mg) of MMF with existing but tolerable and controlled gastrointestinal symptoms. * Recipients who are at least 4 weeks post renal transplantation with stable renal function.

Exclusion criteria

* Multi organ transplant or previous transplant with organ other than kidney * History of GI disorder prior to transplant * Evidence of GI disorder induced by infection, underlying medical condition, or con med other than MMF * Modification of GI med or MMF dose within one week * Evidence of graft rejection, treatment of acute rejection, unstable renal function within 1 week of (baseline) visit Other protocol-defined inclusion/

Design outcomes

Primary

MeasureTime frameDescription
Number of Participants With Response (Yes/no)6 weeksThe primary variable was the response (yes/no) with positive response being defined as an increase of 360 mg/day enteric-coated mycophenolate acid (MPA)from the baseline daily dose, tolerated and maintained for a 4 week duration until the end of the study (Week 6). Tolerability was defined as the overall assessment of improvement or no change in the intensity of physician assessed gastrointestinal (GI) symptoms at end of study as reported on the physician administered evaluation of GI symptomatology.

Secondary

MeasureTime frameDescription
Average Daily Doses (mg) of Enteric-coated Mycophenolate Acid (MPA) and Mycophenolate Mofetil (MMF) by Treatment Duration IntervalsBaseline and week 4 to week 6The average daily doses of enteric-coated mycophenolate acid (MPA) and mycophenolate mofetil (MMF) at baseline and during the last 2 weeks of treatment. 1000 mg MMF = 720 mg enteric-coated MPA (MPA equivalent dose).

Recruitment details

Subjects were recruited in the US from March 2008 to March 2009.

Pre-assignment details

Patients were screened for eligibility. If eligible, willing to participate and provided informed consent, patients were randomized in a blinded fashion to either an equimolar dose of enteric-coated mycophenolate acid (MPA) or remained on the current dose of mycophenolate mofetil (MMF).

Primary

Number of Participants With Response (Yes/no)

The primary variable was the response (yes/no) with positive response being defined as an increase of 360 mg/day enteric-coated mycophenolate acid (MPA)from the baseline daily dose, tolerated and maintained for a 4 week duration until the end of the study (Week 6). Tolerability was defined as the overall assessment of improvement or no change in the intensity of physician assessed gastrointestinal (GI) symptoms at end of study as reported on the physician administered evaluation of GI symptomatology.
