First in Human Study of a Monoclonal Antibody (SOL-116) Targeting BSSL (Bile Salt-Stimulated Lipase), Single and Multiple Dose Parts

Overview

This is a randomized, double-blind, placebo-controlled, first-in-human phase I study. It consists of a single ascending dose part in healthy subjects (Part 1) and in patients with rheumatoid arthritis (Part 2) as well as a multiple dose part in healthy subjects (Part 3). The study will collect information on pharmacokinetics, safety and tolerability.
