Summary:

      This study, designed as a proof of concept study of MCS110 in pigmented villonodular
      synovitis, assessed the clinical response to MCS110 treatment in Pigmented Villonodular
      Synovitis (PVNS) patients, after a single or multiple intravenous doses of MCS110, using
      magnetic resonance imaging to assess tumor volume, and evaluated the
      pharmacokinetics/pharmacodynamics, safety and tolerability in this population.
