Sclerosteosis

This is an open label, Phase 1b, multiple ascending dose, and dose-expansion study of IDP-023 administered in combination with interleukin-2 (IL-2) and ocrelizumab to evaluate the safety, tolerability, and biologic activity on autoreactive immune cells in patients with refractory 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.

Foralumab is a human anti-CD3 monoclonal antibody being developed for the treatment of autoimmune and inflammatory diseases.
The goal of this Phase 2a, randomized, double-blind placebo-controlled, multicenter dose-ranging study is to evaluate the use of nasal foralumab in patients with non-active secondary progressive multiple sclerosis (SPMS).
The primary objectives that this study aims to answer are:
1. To determine the safety and tolerability of 50 μg/dose and 100 μg/dose of foralumab nasal compared to placebo
2. To investigate the effect of foralumab relative to placebo on the change from baseline [18F]PBR06-positron emission tomography (PET) scans for microglial activation, after 12 weeks (3) months of study treatment.
