About OP-145

OP-145 is a novel peptide product that has a unique mechanism of action: it neutralizes the bacterial toxins that often keep chronic middle ear infections active. OP-145 offers potential benefits to patients with chronic otitis media that do not respond to currently available antibiotics and thereby require surgical intervention. Middle ear infections are a very common condition, especially in young children but also in adults, and cause a severe morbidity burden. In addition to chronic middle ear infection, OP-145 shows potential for other indications such as sinusitis and chronic bronchitis. The product has recently started a Phase II study that is part of an ongoing Phase I/IIa clinical trial.
