About First Wave BioPharma, Inc.

First Wave BioPharma is a clinical-stage biopharmaceutical company specializing in the development of targeted, non-systemic therapies for gastrointestinal (GI) diseases. The Company is currently advancing a therapeutic development pipeline with multiple clinical stage programs built around its two proprietary technologies – the biologic adrulipase, a recombinant lipase enzyme designed to enable the digestion of fats and other nutrients, and niclosamide, an oral small molecule with anti-inflammatory properties.
