- Primary Outcome Measures
Name Time Method Main Objective: The main study objective is to assess the frequency and the intensity of the local skin reactions at the end of the treatment course (or before in case of patient withdrawal).;Secondary Objective: The other objectives are to evaluate the drop-outs due to AEs related to local skin reactions, the general safety and the clinical efficacy by the investigator.<br>Patients will evaluate the treatment satisfaction (acceptability), the treatment adherence and the health-related quality of life during the treatment.<br>;Primary end point(s): The primary endpoint in this trial is the Local Skin Reaction (LSR) total score ;Timepoint(s) of evaluation of this end point: at W4, or at an optional visit (LOCF) in case of major local reactions.
