Gastrointestinal Tolerability of MMF vs EC-MPS in Maintenance Transplant Patients Treated With Calcineurin Inhibitors (MOTOR-MPA)

February 16, 2009 updated by: University Health Network, Toronto

A Single Centre, Prospective, Open-Label, Parallel Group, Randomized Study to Compare the Gastrointestinal Tolerability of Mycophenolate Mofetil (MMF, CellCept) and Enteric-Coated Mycophenolate Sodium (EC-MPS, Myfortic) in Maintenance Transplant Patients Treated With Calcineurin Inhibitors

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.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
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
12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
