Design outcomes
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Safety and tolerability of pyrimethan in patients with FALS due to measure safety and tolerability by adverse events, laboratory data, and ability to remain on assigned treatment.;Timepoint(s) of evaluation of this end point: Safety and tolerability will be assessed every week, either during the study visit or by phone interview. | — |
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To evaluate the ability of pyrimethamine to reduce SOD1 protein by 15% in the cerebrospinal fluid in patients with FALS at doses of 75 mg or less.;Secondary Objective: To evaluate the safety and tolerability of pyrimethamine in patients with FALS.;Primary end point(s): reduction of SOD1 protein for 15 % in the cerebrospinal fluid in patients with FALS with pyrimethamin ;Timepoint(s) of evaluation of this end point: last visit (week 36) | — |
