Medical uses
Spesolimab is indicated for the treatment of generalized pustular psoriasis flares in adults.History
The US Food and Drug Administration approved spesolimab based on evidence from a clinical trial of 53 adults with generalized pustular psoriasis flare. The trial was conducted at three sites in the United States and 23 sites globally. Spesolimab was evaluated in one clinical trial of 53 adults with generalized pustular psoriasis flare. In the trial, participants received a single treatment with either spesolimab or placebo. Participants were evaluated for clearance of pustules based on a Generalized Pustular Psoriasis Physician Global Assessment pustulation sub score of 0 at Week 1. Neither the participant nor the healthcare providers knew which treatment was being given until after week 1. After week 1, all participants, whether they initially received spesolimab or placebo, who continued to experience flare symptoms, had the option to receive a single open-label treatment of spesolimab. After week 1 to week 12, participants in either original treatment group whose generalized pustular psoriasis flare reoccurred after achieving a clinical response were eligible to receive a single open-label rescue treatment of spesolimab, with a maximum of three total treatments of spesolimab throughout the trial.Society and culture
