NCT05032131

Brief Summary

Inclusion Body Myositis is a slowly but disabling myopathy, the most frequent in patients over 50 years old. No treatments (in particular immunosuppressive) are known to be efficient. Autologous uncultured adipose-derived stromal vascular fraction (ADSVF) is recognized as an easily accessible (by a standard liposuction to obtain adipose tissue, from which ADSVF are isolated by centrifugation), safe and well tolerated source of cells with angiogenic, anti-inflammatory, immunomodulatory and regenerative properties. The purpose of our ADSVF in IBM phase I trial is to evaluate, for the first time in human diseased muscle, first the tolerance of autologous ADSVF cells locally injected in affected forearm muscles and second their capability to repair those muscles. With always the goals of tolerance first and second muscle repair, we will recruit in parallel two groups of IBM patients: the first treated by sirolimus since at least 6 months (but still disabled) and the second currently (for at least 3 months) without specific treatment for inclusion myositis.

Outcome Measures

Primary Outcomes (1)

  • In each group, tolerance of escalating doses (3+3) of ADSVF in the non-dominant forearm

    By determining the dose-limiting toxicity (DLT)

    Days 0 (day of the injection) to day 30

Secondary Outcomes (4)

  • In each group, tolerance of escalating doses (3+3) of ADSVF in the non-dominant forearm

    Days 0 (day of the injection) to 6 months (end of participation)

  • In each group, efficacy in term of muscle repair (regenerative properties of ADSVF)

    At day 30, 3 month and 6 month

  • In each group, efficacy in term of muscle repair (regenerative properties of ADSVF)

    At 6 month

  • In each group, evaluation of muscle inflammation control

    At 6 month
