Primary Outcome(s)
Primary end point(s): The primary endpoint is the cumulative number of new or enlarging Gd+ lesions at month 9

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.

Whether controlled parasitic infection with N. americanus (25 larvae per patient) reduces relapses and disability in MS patients compared with placebo.
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.
