Relative Bioavailability Study of HNC364 Injectable Suspension

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.

Treatment and study plan

HNC364 Injectable Suspension

Drug

Subjects in HNC364 cohort will receive a deep IM injection of HNC364 injectable suspension in the deltoid muscle at a dose of 60 mg every 4 weeks for 4 repeated doses. Subjects will be allowed to leave the clinical site the next day after receiving each dose and return to clinical site on 7 days, 14 days and 28 days (before next administration) after each dose for safety and tolerability assessments. Besides, subjects will return to the clinical site on 4 days after the first dose and the last dose due to PK and PD blood sample collections.

Rasagiline Tablets

Drug

Subjects in rasagiline tablets cohort will receive 1 mg of rasagiline tablets orally once daily for 20 days, followed by 2 mg once daily for 5 days. Subjects will remain domiciled at the clinic stay until Day 26 and have a follow-up visit on Day 29 due to PK and PD blood sample collections

Primary outcomes

  1. Area under the concentration-time curve (AUC) from time 0 to dose interval (AUCτ)

    Time frame: Day 1 to 56 days post dose

    The relative bioavailability of HNC364 injectable suspension and rasagiline tablets at the steady-state will be calculated by comparing the following PK parameters of rasagiline in both formulations.

    Due to the negligible plasma concentrations of HNC364 observed following intramuscular injection, the relative bioavailability calculations will be based on the assumption of complete conversion of HNC364 to rasagiline in vivo. To facilitate this comparison, the administered dose of HNC364 (60 mg) will be converted to an equivalent dose of rasagiline based on their respective molecular weights: 60 mg * 171.24 / 624.91 = 16.44 mg.

  2. Number of Participants With Treatment Emergent Adverse Events

    Time frame: Day 1 to 56 days post dose

    The following assessments will be used to evaluate the safety of HNC364 and rasagiline: monitoring and assessment of adverse events (AEs) and concomitant medications; 12-lead electrocardiograms (ECGs); vital sign measurements (including blood pressure, heart rate, respiratory rate, and oral temperature); clinical laboratory test results (including serum chemistry, hematology, coagulation, and urinalysis); physical examinations and injection site reactions.
