Clinical Trial Summary

Psoriasis is a chronic inflammatory disease that affects between 2% and 4% of the French population.Some specific localizations are more difficult to manage, such as the scalp, nails, genital region and palmoplantar localizations.

Tildrakizumab, an anti-interleukin-23 (IL-23) monoclonal antibody, has demonstrated efficacy and safety in the treatment of patients with moderate to severe psoriasis.

Real-life data on the efficacy of Tildrakizumab in unselected patients with these difficult-to-treat locations are still limited.

The aim of the ZODIPSO study is to evaluate the efficacy and safety of Tildrakizumab in patients presented difficult to treat locations in psoriasis : nail, scalp, genital and palmoplantar.

The main objective is to assess the overall response and the specific response to Tildrakizumab at these specific areas up to W52.

Description:

Psoriasis is a chronic inflammatory disease that affects between 2% and 4% of the French population. Some specific localizations are more difficult to manage, such as the scalp, nails, genital region and palmoplantar localizations. They are reported at least once during the course of psoriatic disease in more than 80%, 50%, 60%, 12% of patients, respectively.

Despite recent progress in the management of the disease, these localizations remain a challenge for psoriasis patients because of their impact on quality of life and the difficulty of treating them.

Tildrakizumab, an anti-interleukin-23 (IL-23) monoclonal antibody, has already demonstrated efficacy and safety in the treatment of patients with moderate to severe psoriasis in two international multicenter randomized clinical trials : reSURFACE 1 and reSURFACE 2. However, real-life data on the efficacy of Tildrakizumab in unselected patients with these difficult-to-treat locations are still limited.
