Safety, Tolerability and Immune Effects of the Nasal Foralumab in Healthy Human Volunteers

A Phase I Study of the Safety, Tolerability and Immune Effects of the Nasal Anti-CD3 Monoclonal Antibody Foralumab in Healthy Human Volunteers

The goal is to establish the safety of administration of nasal foralumab to healthy volunteers in escalating doses to determine the dose at which immune effects are observed. Patients will receive doses for 5 consecutive days and have a follow-up period.

This was a randomized, double blind phase 1 dose escalation study evaluating 3 dose levels of foralumab via intranasal administration from single-dose vials. The rationale behind the proposed research was to establish an immunologically active dose of foralumab given by the nasal route. Given that foralumab has never been administered by the nasal route to humans, this was a safety and dose finding study. Each dose group was observed until Day 7 to assess safety before moving to the next higher dose. This study also helped determine the dose at which immune effects (induction of regulatory T cells and changes in cytokine profiles of immune cells) were observed in subjects treated with foralumab.
