About

This trial will study the safety and efficacy of subcutaneous semaglutide for the treatment of Systemic Sclerosis

Full description

Systemic Sclerosis (Ssc) is a rare, systemic autoimmune disease characterized by skin fibrosis and vasculopathy. In addition to the skin, it is a heterogeneous disease that affects multiple organs, including the cardiac, pulmonary, and gastrointestinal systems. This is a small prospective and open-label clinical trial of semaglutide in adults with systemic slceorsis. 10 systemic sclerosis patients will be recruited and receive semaglutide for 24 weeks. The primary endpoint of the study is the change in mRSS at 24 weeks of treatment.

Enrollment: 10 estimated patients

Sex: All

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers
