简要总结

Methodology :Phase III study, single centre, double blind, versus excipient, randomised, controlateral design.

Selection of the patients :Number of subjects required 60 :

  • 30 patients needing an oral corticotherapy
  • 30 patients needing a topical corticotherapy

详细描述

Study conduct

Two steps for each patient:

  1. the first step lasting 3 months : assessment of changes in mechanisms involved in ACIC with the RV3391A cream (M0 à M3). At the beginning of the corticotherapy, each patient will apply RV3391A on anterior side of a forearm and the placebo on the other side (randomised) for 3 months.

Clinical exam and objective measurements will be realised.

This step will allow us to describe and compare the evolution of cutaneous atrophy's markers produced by glucocorticoïds markers between M0 and M3:

  • between topical and oral corticotherapy
  • between RV3391A and the placebo.
  1. the second step, the cohort follow-up, leading off the end of the first step (M3 à M24) The period of the second step will depend on the progression of patient's disease and on the period of his medical follow-up. This period may lasting until the 24th month after the inclusion in the study.
