Study Description
Brief Summary:

Sporadic Inclusion Body Myositis (IBM) is the most frequent inflammatory myopathy in patients over 50. It is a slowly progressive, but today untreatable (notably by classical immunosuppressants) disease.

Rapamycin used in organ transplantation blocks the activity of T effector cells, preserves T regulatory cells and induces autophagy (protein degradation), all parameters impaired during IBM.

RAPAMI is a prospective, randomised, controlled, double blind, monocentric, phase IIb trial evaluating rapamycine against placebo.
