Overview

HNC364 is a new pro-drug of rasagiline as a long-acting injection for deep IM deltoid injection, for the treatment of Parkinson"s disease (PD). As a pro-drug of rasagiline, HNC364 will readily and completely convert to rasagiline after the IM administration.

This is a non-randomized, open-label, Phase 1 study to evaluate the relative bioavailability of HNC364 injectable suspension relative to AZILECT® (rasagiline tablets), to assess the safety and tolerability of multiple IM dose HNC364 injectable suspension dose administration in healthy adult subjects.
