Clinical Trial Alert: Phase 2 Study of Ravulizumab (Ultomiris) in Adults Living with Dermatomyositis

Researchers at Alexion Pharmaceuticals are seeking adults living with dermatomyositis to participate in a phase 2 clinical trial to evaluate the safety, effectiveness, and pharmacological properties of the investigational drug ravulizumab (Ultomiris). Ravulizumab is designed to target a component of the immune system (known as complement), which underlies many autoimmune disorders including dermatomyositis. Treatment with ravulizumab has the potential to improve the muscle weakness and skin manifestations associated with dermatomyositis.

This is a phase 2/3 double-blind, randomized, placebo-controlled, multicenter study, which means that participants at different study sites will be randomly assigned to receive the drug or an inactive placebo control. The phase 2 portion of the trial (part A) is actively enrolling. Participants enrolled in part A will not be able to enroll in the phase 3 portion of the trial (part B). In part A, participants will be required to attend six clinic visits over the course of the study. The trial duration will include a 4-week screening period, followed by a 26-week treatment period.

The drug will be administered intravenously (injection in the vein). Participants will be evaluated using a combination of health- and function-related questionnaires, physical assessments, and laboratory testing.

To be eligible, individuals must meet the following inclusion criteria:

  • Diagnosis of dermatomyositis
  • At least 18 years of age
  • Inadequate response and/or intolerant to two or more dermatomyositis treatments
  • No cancer-associated myositis
  • May be eligible if on a stable dose of steroids or immunosuppressive treatments or willing to complete a washout period

Individuals may not be eligible to participate if they are affected by another illness or receiving another treatment that might interfere with the ability to undergo safe testing.
