Design outcomes

Primary

MeasureTime frame
Main Objective: The main objective of this study is to assess CYT107 efficacy on JCV clearance from cerebrospinal fluid.;Secondary Objective: The secondary objectives of this study are: o to assess the clinical safety of CYT107 o to assess the effect on patient survival o to measure the effect on neurological and clinical status o to assess the biological activity of CYT107: - on the kinetics of JCV reduction in CSF - on the main parameters of the immune reconstitution - on the specific T-cell response against the JC virus ;Primary end point(s): The primary endpoint is defined as the clearance of the JCV from the CSF at M3.;Timepoint(s) of evaluation of this end point: The primary endpoint will be assessed at 3 months.

Secondary

MeasureTime frame
Secondary end point(s): The secondary endpoints are: • Kinetics of the JC viral load changes • “Survival” curves for time to JCV viral clearance in CSF • MRI lesions changes • Percentage change in neurological scores • Change in Karnofsky Performance Status; • MRS scores • Proportion of patients with a MRS score < 3 • Changes in CD4+ and CD8+ T-cell subsets • Changes of specific T-cell responses, proliferation indices, JCV-specific T-cell responses • Survival rate ;Timepoint(s) of evaluation of this end point: Timepoints of evaluation of secondary endpoints are as follows: • Kinetics of the JCV viral load changes from D0 to M3 • Kinetics of the JCV viral load changes from D0 to M12 • “Survival” curves for time to JCV viral clearance in CSF • Percentage change in neurological scores between baseline and M12 • Change in Karnofsky Performance Status between D0 and M12; • MRS scores at M12 • Survival rate at M12
