Study Designed to Evaluate the Safety, Tolerability, and PK of RAP-219 Formulated as an Long Acting Injectable.
A Phase 1, Double-blind, Placebo-controlled, Single- and Multiple-dose Study of the Safety, Tolerability, and Pharmacokinetics of RAP-219 Administered as a Long-acting Injectable to Healthy Participants
This is a Phase 1, double-blind, placebo-controlled, 5-cohort study evaluating the pharmacokinetics (PK), safety, and tolerability of RAP-219-LAI in healthy participants aged 18 to 65 years. Assessment of up to four single-dose cohorts will characterize the PK profile of up to four ascending dose levels and evaluate dose proportionality. One multiple-dose cohort will characterize the accumulation profile of RAP-219-LAI.
The study includes a Screening Period of up to 28 days (Day -28 to Day -1) for participants in all cohorts. Cohorts 1, 2, 3, and 4 will include admission on Day -1, a single dosing day (Day 1), a 28-day inpatient and outpatient Treatment Period (Day 1 to Day 28), and a 28-day Follow-up Period (Day 29 to Day 56). Cohort 5 will include admission on Day -1 and Day 28, two dosing days (Day 1 and Day 29), a 56-day inpatient and outpatient Treatment Period (Day 1 to Day 56), and a 28-day Follow-up Period (Day 57 to Day 84).
Up to 60 participants are planned to be enrolled in this study, with 12 participants per cohort randomized in a 3:1 ratio to receive RAP-219-LAI or placebo.
Studie Overzicht
Gedetailleerde beschrijving
Participants will be randomized to receive a single dose of RAP-219-long acting injectable (LAI) (RAP-219-LAI) nanosuspension or placebo (Cohort 1, Cohort 2, Cohort 3, and Cohort 4), or 2 doses of RAP-219-LAI or placebo (Cohort 5) 28 days apart. A starting dose of 2.5 mg for Cohort 1 was chosen based on reviews of the preclinical data, clinical trials data and PK modelling and simulation. A sentinel group of 2 participants will be dosed and monitored for 24 hours. The rest of that cohort (8) will be dosed if there are no safety concerns noted with the sentinel group. A dose escalation committee (DEC) will review the safety and available PK data for cohort 1 and make a determination on the dose for Cohort 2. The DEC will review the data for subsequent cohorts and advise on does as well as study progression based on the emerging and cumulative safety and PK data.
