Evaluation of the Efficacy and Safety of the Medical Device PROXERA PSOMED 20 in Reducing Psoriatic Plaques and of the Medical Device PROXERA PSOMED 40 in Reducing Non-pustulous Palmoplantar Psoriasis Flaw in Patients With Plaque Psoriasis: a Sponsored, Interventional, Single-center, Randomized, Single-blind, Intra-patient Controlled Study (PASI)
This single-center interventional study was designed to evaluate the efficacy and safety of two CE-marked topical medical devices: PROXERA PSOMED 20 is being studied in participants with non-palmoplantar plaque psoriasis, while PROXERA PSOMED 40 is being studied in participants with non-pustular palmoplantar psoriasis. The study aims to determine whether treating a target area with the assigned medical device leads to greater clinical improvement compared to the untreated contralateral control area in the same participant. For PROXERA PSOMED 20, the primary assessment is performed after 4 weeks of treatment. For PROXERA PSOMED 40, the primary assessment is performed after 8 weeks of treatment. Secondary objectives include the assessment of safety, local tolerability, overall psoriasis progress, its impact on quality of life, and additional parameters of local disease activity at the target areas. Participants will apply the assigned study device once daily to the selected target area, undergo clinical assessments at scheduled visits, and provide safety and tolerability information throughout the study.
