- Primary Outcome Measures
Name Time Method Main Objective: Whether controlled parasitic infection with N. americanus (25 larvae per patient) reduces the cumulative number of gadolinium enhancing (Gd+) lesions in MS at month 9 in comparison to baseline and placebo.;Primary end point(s): The primary endpoint is the cumulative number of new or enlarging Gd+ lesions at month 9;<br> Secondary Objective: Whether controlled parasitic infection with N. americanus (25 larvae per patient) induces an increase in foxp3 positive (CD4+Cd25high) T cells (Treg) in people with MS in comparison to baseline and placebo.<br><br> Whether controlled parasitic infection with N. americanus (25 larvae per patient) reduces relapses and disability in MS patients compared with placebo.<br>
