Summary:

There is a need for longer-acting prophylactic pharmacologic options for opioid use disorder (OUD) patients during maintenance therapy. This study tests a titanium implant loaded with a formulation of naltrexone and a naturally occurring carboxylic acid. The device is implanted subcutaneously with local anesthetic during an in-office procedure. The technology is based on a unique formulation that keeps the pH within the reservoir low and promotes passive diffusion of naltrexone. The benefits of the product include complete medication adherence for one year after administration, fewer relapses, smooth profile ensuring complete prophylaxis without sub-therapeutic plasma troughs, full reversibility, and similar efficacy with less drug exposure. This technology has been validated clinically with another drug and tested preclinically with naltrexone. This project will finalize the chemistry manufacturing and controls, produce IND supplies, conduct an IND-enabling safety study, and submit the IND.
