Omiganan (previously known as MBI-226), is a synthetic, linear, 12 amino acid, cationic peptide analog of indolicidin, being developed as a topical gel for prevention of catheter-associated infections. In September 2000, a phase III trial of omiganan for the potential prevention of catheter-related bloodstream infections was initiated. In July 2018 was completed phase III clinical trial where was evaluated the long-term safety of once-daily application of omiganan topical gel in subjects with severe papulopustular rosacea. In addition, omiganan successfully completed phase II clinical trials where was determined its safety/tolerability in patients with mild to moderate atopic dermatitis and in human subjects with facial acne vulgaris. Besides, omiganan is ongoing phase II to explore the efficacy and pharmacodynamic effects of its topical gel in facial seborrheic dermatitis.
