APEPTICO has completed a phase I clinical trial for its pulmonary sodium ion channel activator AP301. The orally inhaled drug candidate was safe and well-tolerated by all study participants. AP301 is being developed for the prevention and treatment of oedematous respiratory failure in patients suffering from lung infection, lung injury and lung transplantation.
The phase I single-center clinical trial evaluated the safety, tolerability and pharmacokinetic profile of AP301 in an orally inhaled, double-blind, randomized, placebo-controlled, dose escalation study in 48 healthy male volunteers. AP301 was shown to be safe at all doses investigated, with no reports of serious adverse side effects.
AP301 is the first compound against respiratory failure caused by pulmonary oedema that activates lung oedema reabsorption and thus differs from the currently used anti-inflammatory treatment that often fails in patients with acute lung injury. The synthetic peptide AP301 activates alveolar liquid clearance (ALC) and prevents both endothelial and epithelial lung tissue from hyper-permeability as a result of microbial and viral lung infections. AP301 also prevents ischaemia reperfusion injury following lung transplantation in the lower respiratory tract.
