- Original description
The goal of this clinical trial is to assess the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and potential efficacy of IM-101 in adult participants with AChR antibody-positive gMG. Subsequently, the safety and efficacy of the selected IM-101 dose-regimen will be tested in participants with AChR antibody-negative gMG and participants with AChR antibody-positive or AChR antibody-negative oMG.Read full original descriptionShow less
