Study summary

The purpose of the study is to assess the gastrointestinal tolerability of EC-MPS compared to MMF in maintenance transplant patients on a calcineurin inhibitor regimen, who require MMF dose reductions of 25% or more due to GI complications. The tested hypothesis is that the EC-MPS treatment is superior to the MMF therapy in terms of tolerability and that patients on the EC-MPS formulation will be able to tolerate higher doses compared to those on MMF.

Read the detailed description

The use of mycophenolate mofetil (MMF) in combination with a calcineurin inhibitor (CNI: tacrolimus or cyclosporine) has been shown to improve graft survival in renal, cardiac and liver transplantation patients. However, its use has been associated with significant side effects, including gastrointestinal complications, causing dose reductions, interruption or termination of the therapy. An alternate formulation: enteric coated mycophenolate sodium (EC-MPS) was designed to alleviate the severity of upper gastrointestinal side effects. Several trials detailed in the protocol suggest a benefit in GI related health following conversion from MMF to EC-MPS, however we believe that robust data are lacking.

What researchers measure

Primary outcomes

  1. The number of patients with at least 1 GI symptom that is continuing or starting after the 1-month dose stabilization period

    Time frame: 12 months

Secondary outcomes

  1. Analysis and comparison of various Gastrointestinal Symptom Rating and Quality of Life Questionnaire (the GSRS, GIQLI, PGWB,OTE for HRQoL) scores across and within the 2 cohorts.

    Time frame: At months 1, 3, 6, 12 post-study start

  2. Incidence and severity of adverse events

    Time frame: months 3, 6, 12

  3. Patient survival, graft survival and rejection episodes across the 2 cohorts

    Time frame: months 3, 6, 12

  4. Dose reductions, interruptions, fractionations and patient withdrawals across the two cohorts due to adverse events

    Time frame: Months 6, 12
