NCT07530367
Palmoplantar pustulosis (PPP) is a rare, chronic inflammatory skin disease primarily affecting the palms and soles. Currently, no treatment is specifically approved for PPP globally. This study aims to evaluate the efficacy and safety of tofacitinib combined with imatinib in patients with moderate-to-severe PPP.
NCT07503652
Palmoplantar pustulosis (PPP) is a chronic and recurrent skin disease, mainly characterized by erythema, pustules and scales on the palms and soles, often accompanied by itching and pain, which seriously affects the quality of life of patients. Currently, the treatment options for PPP are limited. Traditional therapies such as topical glucocorticoids, phototherapy and oral immunosuppressants have unsatisfactory efficacy, and long-term use may cause significant side effects. The introduction of biologics has provided a new direction for the treatment of PPP, but targeted therapy research for PPP is still scarce, and there are unmet clinical needs. The exploratory study of Xeligekimab in PPP is expected to provide a new treatment option, alleviate symptoms and improve the quality of life of patients. This study takes the domestic Xeligekimab as the research object, aiming to verify its potential in PPP and contribute to the breakthrough of domestic biologics in the field of refractory skin diseases. If the study is successful, it can provide preliminary evidence support for the addition of PPP as an indication for Xeligekimab and offer a preliminary theoretical basis for adding a new option to targeted therapy for PPP.
NCT04451720
Palmoplantar pustulosis is a chronic inflammatory skin disease that causes repeated on and off symptoms like erythema (reddening, irritation), vesicle (swelling, cyst), pustules, scale, and crusts in palms and soles. This study evaluates how well risankizumab works compared to placebo (no medicine) to treat palmoplantar pustulosis. Study will assess change in Palmoplantar Pustulosis Area and Severity Index \[PPPASI\]. Risankizumab is an investigational drug being developed for the treatment of palmoplantar pustulosis. This study is "double-blinded", which means that neither the trial participants nor the study doctors will know who will be given study drug and who will receive placebo (no medicine). Participants are randomly put into 1 of 2 groups, called treatment arms to receive risankizumab or placebo in period A. In period B, each group receives both risankizumab and placebo at different time intervals. Around 116 adult participants with palmoplantar pustulosis will be enrolled in approximately 39 sites across Japan. Participants will receive subcutaneous (SC) injections of risankizumab or placebo at Week 0 and Week 4 (Period A). Beginning Week 16 (Period B), both the groups will receive risankizumab and placebo at different intervals. Total treatment duration is 56 weeks. There may be a higher burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the course of the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
