Pivotal Trial
Summary
This trial is testing a new medicine called PF-06823859 for adults with muscle inflammation diseases DM and PM. The goal is to see if it can safely reduce muscle inflammation and weakness.
Who is the study for?
This trial is for adults over 18 with active Dermatomyositis (DM) or Polymyositis (PM), who are on a stable dose of corticosteroids or immunosuppressants. It's not suitable for those not meeting the specific disease criteria or unable to follow the study protocol.
What is being tested?
The trial tests PF-06823859, given as an IV infusion every 4 weeks against a placebo, to see if it's safe and effective in treating muscle inflammation and weakness caused by DM and PM over approximately 13 months with up to 16 visits.
What are the potential side effects?
Potential side effects of PF-06823859 may include reactions at the infusion site, increased risk of infections due to immune system suppression, fatigue, headache, nausea, but specifics will be monitored throughout the study.

Other Research
Common treatments for Myositis, such as corticosteroids, immunosuppressants (e.g., methotrexate, azathioprine), and newer agents like PF-06823859, primarily work by modulating the immune system and reducing inflammation. Corticosteroids decrease inflammation by suppressing the immune response, while immunosuppressants inhibit the activity of immune cells that attack muscle tissue.
PF-06823859, an investigational drug, aims to further modulate immune pathways to reduce muscle inflammation and improve muscle function. These treatments are crucial for Myositis patients as they help alleviate muscle weakness, improve mobility, and prevent long-term damage caused by chronic inflammation.
