Study summary

The main autoimmune bullous dermatoses are pemphigus and cicatricial pemphigoid. Pemphigus is an autoimmune dermatological disease characterized by the production of anti-desmoclesin antibodies 1 and 3, affecting the skin and mucous membranes.The cicatricial pemphigoid is an autoimmune dermatological disease, characterized by the production of anti-zone antibodies of the basal membrane and characterized by a predominant mucosal involvement. Mycophenolic acid (MPA) is an increasingly used form of corticosteroid. Despite its increasing use, pharmacokinetics in autoimmune bullous dermatosis remain little studied.

    60 patients will be used to build and validate the system

    The first 30 patients will be used to build and validate the pharmacokinetic modeling of MPA in pemphigus.The 30 patients included later will provide additional data.

    Drug: Cellcept® in autoimmune bullous dermatoses

Interventions

    The administration will follow the recommendations for the use of Cellcept® in autoimmune bullous dermatoses

What researchers measure

Primary outcomes

  1. Evaluation of the Bayesian estimator performance

    The evaluation of the Bayesian estimator performance will be based on its capacity to predict MPA AUC (Area Under the Curve), expressed as the bias (%) and the precision (root mean square error; RMSE) between the predicted AUC calculated using a limited number of samples performed in the first 4 hours post dosing and the observed AUC estimated using the reference method (trapezoidal rule method). A Bland Altman curve will be constructed.

    Time frame: 8 hours

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 22, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
