OptiNose reports positive results from Phase 1 trial of intranasal oxytocin for autism

OptiNose has announced that a study comparing OPN-300 intranasal oxytocin to intravenous oxytocin for the treatment of autism showed the achievement of similar blood levels but significantly greater social-cognitive effects after intranasal administration. The results were published online July 14, 2015 in Translational Psychiatry.

The randomized, placebo-controlled, double-blind, double-dummy, 4-arm cross-over study involved 16 healthy volunteers who received either intravenous oxytocin or two doses of OPN-300 delivered using OptiNose’s bi-directional breath powered intranasal delivery device. Social-cognitive effects were measured by emotional rating of facial images.

Researcher Ole A. Andreassen of the University of Oslo said, “The OptiNose technology significantly changes the way drug is delivered high up in the nose, and may be the drug delivery solution we’ve been looking for. If we can improve social cognition in healthy people with OPN-300 low-dose oxytocin, then we may be able to address a core symptom suffered by millions of patients worldwide with autism.”

OptiNose Chief Scientific Officer Per Djupesland commented, “Although animal data has been encouraging, many would argue that medication transport from the nasal cavity directly to the brain has not been previously proven in humans. Today’s results are quite promising and bolster our belief that we can enable and enhance the treatment of common brain disorders with OptiNose delivery technology.”

The company says that it is initiating a Phase 2 trial of OPN-300 in autism patients in Norway. OptiNose is also developing intranasal fluticasone for chronic sinusitis and recently reported positive results from a Phase 3 trial of that product.
