Summary

This is a first-in-human (FIH), Phase 1 study of orally administered SAT-3247 in healthy adult volunteers (HVs) and adult participants with DMD to determine safety, tolerability, pharmacokinetics and pharmacodynamics.

Detailed description

This is a first-in-human (FIH), Phase 1 study of orally administered SAT-3247 in healthy volunteers (HVs) and adult participants with DMD. The study will be conducted in 4 parts. Part A is a Single Ascending Dose (SAD) part that will enroll approximately 40 HVs in up to 5 dose cohorts. Each participant will receive a single oral dose of SAT 3247 or matched placebo on Day 1; each cohort will receive a higher dose than the prior cohort. Part B is a Multiple Ascending Dose (MAD) part that will enroll approximately 32 HVs in up to 4 sequential dose cohorts. Each participant will receive a daily oral dose of SAT-3247 or matched placebo on Day 1 to Day 7 each cohort will receive a higher dose than the prior cohort. Part C will assess the effect of food on the PK of SAT-3247 in a fixed sequence, crossover design. The dose to be tested will be determined by the Safety Review Committee (SRC) following review of safety, tolerability, and available PK and PD data from Part A. Approximately 8 healthy participants who completed Part A at the anticipated dose level (in a fasted state) will crossover into a subsequent fed cohort and receive a single dose of the same randomized IP at the same dose level that they received in Part A but, following a high fat meal. Part D is a open-label Multiple Dose cohort that will comprise 10 adult males with genetically confirmed DMD. Each participant will receive SAT-3247 once daily for 5 consecutive days of each of 4 weeks

Interventions

Type	Name	Description
DRUG	SAT-3247	SAT-3247 is an oral tablet that is a potent, muscle penetrant, small molecule inhibitor of AAK1; inhibition of AAK1 rescues perturbed asymmetric division of satellite stem cells, resulting in increased muscle regeneration in animal models of DMD. In vitro and in vivo animal pharmacology studies have demonstrated the efficacy of SAT-3247 in improving muscle strength and the necessary target coverage to maximize functional muscle improvement.
