About Iseganan

Iseganan hydrochloride (HCl) oral solution is a broad-spectrum antimicrobial peptide that functions by a novel mechanism of action, which may substantially reduce the likelihood of microbial resistance. Iseganan is the first in a new class of investigational peptide drugs known as protegrins, which are naturally-occurring substances found in mammals where they form part of the first line of defense against invading bacteria and fungi.

About Ventilator-Associated Pneumonia (VAP)

Pneumonia is the most common infection among ventilated patients in the intensive care unit. The longer a patient is ventilated, the higher the risk of developing VAP. Approximately 15-30% of patients receiving mechanical ventilation for more than 48 hours get VAP. The Company estimates that over 1 million patients annually are mechanically ventilated for more than 48 hours in North America, Western Europe and Japan combined, making VAP a significant unmet medical need. Despite the use of potent, broad-spectrum, antibiotics, patients who develop VAP generally remain dependent on artificial ventilation and remain in the intensive care unit for longer periods of time than patients who do not develop VAP. As a consequence, studies have demonstrated that patients who develop VAP can incur more than $40,000 in additional hospital charges.
