About this study

Generalised pustular psoriasis is a rare skin disorder that presents with flares of widespread pustules on a background of red and tender skin. It can be treated with special creams for the skin, tablets or injections.

The investigational drug for this study is called spesolimab and is given as an injection into the skin.

The purpose of this research project is to measure how safe and effective this medication is in treating participants with generalised pustular psoriasis. Prior research studies in humans have shown that this medication may help control the immune system that is responsible for the signs and symptoms of generalised pustular psoriasis and help achieve disease improvement.
