Interest of Mycophenolate for CIDP Weaning (MYCOPID)

March 14, 2019 updated by: Assistance Publique - Hôpitaux de Paris

Does the Mycophenolate Improve the Ability of Weaning Patients Off the Treatment in Chronic Inflammatory Demyelinating Polyradiculopathy (CIDP)

The main objective is to study if the mycophenolate could decrease the proportion of patients who relapse during the IVIG tapering period and after the IVIG withdrawal.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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 secondary objectives are :

  • Study if the mycophenolate could improve the proportion of withdrew patients.
  • Study if the mycophenolate could improve the reduction of IVIG dose or could prolong the interval between two courses of IVIG compared to the baseline interval at month 12 and month 24 (= sparing treatment criteria).
  • Study if mycophenolate could short the delay to perform the IVIG withdrawal.
  • Study if mycophenolate could improve the clinical scores (ONLS, R-ODS MRC, INCAT sensory, 10 meters test) or pain score at month 12 and month 24.
  • Study if mycophenolate could improve the quality of life at month12 and month 24.
  • Identify clinical, biological and electrophysiological factors associated with withdrawal.
  • To assess the pharmacokinetics factors (Area under the curve measuring the exposure to mycophenolate) and the pharmacogenetic factors (cytochrome and carrier, FcgammaR) associated with withdrawal.
  • Evaluate the tolerance of Mycophenolate in this new indication.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

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.

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
Measure Description
Time Frame
occurrence of a relapse during the tapering off period
Time Frame: up to 18 months

occurrence of a relapse during the tapering off period (up to 18 months after baseline) or after the withdrawal during the monitoring period.

(the withdrawal is defined by the ability to reach the last day of IVIG treatment)
up to 18 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.
