Study Summary

This is a Phase 1, single-center, open-label, single ascending dose study to assess the PK, safety, and tolerability of SYN-020 delayed release capsules administered orally to healthy adult male and female subjects with a BMI of 18.5 to 27 kg/m2. Up to 36 subjects will participate, in each of up to 6 sequential cohorts. Single doses of 5, 15, 45, and 150 mg SYN-020 are planned in Cohorts 1 through 4, respectively. Cohorts 5 and 6, if enrolled, will receive doses that were well tolerated in an earlier cohort to determine the effect of BMI and/or a high-fat meal on the SYN-020 PK profile. For each cohort, eligible subjects will be admitted to the clinic on Day -1, and receive study drug in the morning of Day 1. For PK analysis, blood and feces will be collected before dosing and for up to 96 hours (blood) or 120 hours (feces) after dosing. Subjects will be discharged from the clinic after the End of Study procedures are completed on Day 6.
