Intermediate-Size Patient Population Expanded Access: Foralumab in Non-Active Secondary Progressive MS Patients

This is an open-label, intermediate-size patient population expanded access treatment study utilizing 1 dose level of nasal Foralumab (50 µg/dosing day) with the possibility of increasing to 100 µg/dosing day. The goal of this expanded access clinical trial is to evaluate safety, tolerability, and immune effects of intranasal Foralumab in non-active secondary progressive multiple sclerosis patients. The primary objective is to treat patients who have failed current available therapy. Participants will visit the clinic for testing and follow-up every cycle (3 weeks) while administering the medication at home if able three times weekly.
