Overview
The purpose of this study is to assess the safety, tolerability and pharmacokinetics of PDM608 in healthy adult subjects.
Description
This is a 2-part, single-center, first-in-human study of single ascending doses (SAD; Part 1) and multiple ascending doses (MAD; Part 2) of PDM608 in healthy adult subjects.
Part 1 is a double-blind, randomized, placebo-controlled assessment of subcutaneous (SC) SAD administrations of PDM608 across 5 cohorts of subjects. All SAD cohorts will follow a sentinel design. Following completion of each cohort, safety and tolerability data through 96 hours post-dose will be reviewed to determine whether to progress to the next dose level and the dose level for the next cohort.
Part 2 is a double-blind, randomized, placebo-controlled assessment of SC MAD administrations (once weekly for 4 weeks) of PDM608 across up to 4 cohorts of subjects. Following completion of each cohort the safety and tolerability data 96 hours post last dose will be reviewed to determine whether to progress to the next dose level and the dose level to be administered.
