PF329: ER hydromorphone prodrug

Early-stage clinical trials were conducted with PF329, an extended-release prodrug of hydromorphone.  

  • In two phase 1 studies, PF329 has demonstrated excellent safety, dose proportionality, and a clinically beneficial extended release profile. 

  • A Fast Fed study showed little effect on activation of PF329 or its pharmacokinetic profile.
