Non-Active Secondary Progressive Multiple Sclerosis

Only subjects that have completed TILS-021, a Phase 2a Randomized, Double-Blind, Placebo-Controlled, Multicenter Dose-Ranging Study of Nasal Foralumab in Non-Active Secondary Progressive Multiple Sclerosis Patients are eligible to be enrolled in TILS-022. TILS-022 is a 6-month open-label extension study with an opportunity for dose to be escalated based on the subject's clinical status. All subjects initiate dosing in this trial at a dose of nasal foralumab 50 µg 3 days a week (Monday, Wednesday, and Friday) for 2 weeks, followed by a 1-week rest, comprising a 3-week cycle. At week 12, the dose may be escalated to 100 µg according to pre-defined dose escalation rules. Study TILS-022 is intended to ensure all participants in TILS-021, a placebo-controlled study, will be able to receive open-label nasal foralumab for 6 months. The option to extend this trial for longer than 6 months will be explored with FDA by the Sponsor.

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.
