|Condition or disease||Intervention/treatment||Phase|
|Phenylketonuria Healthy||Drug: SYNB1618 Drug: Placebo||Phase 1 Phase 2|
This Phase 1/2a, first-in-human, oral single and multiple dose-escalation, randomized, double-blinded, placebo-controlled study of SYNB1618 in healthy adult volunteers and adult subjects with phenylketonuria will evaluate safety, tolerability, kinetics, and pharmacodynamics within the following 2 study parts:
Part 1 comprises a single-ascending dose (SAD) study conducted (3 treated:1 placebo) over 4 days in HV male and female subjects evaluated in up to 6 dose cohorts to identify maximum tolerated dose (MTD) within the single dose-dose range studied. Up to 24 healthy subjects may be enrolled in this part of the study. Following attainment of the MTD in HV, a SAD cohort of up to 4 subjects (male and female, >18 years old) previously diagnosed with PKU will be enrolled (3 treated:1 placebo).
Part 2 comprises a multiple-ascending dose (MAD) study conducted in an inpatient setting (6 treated:2 placebo) over 10 days in HV male and female subjects evaluated in up to 4 cohorts at doses that will not exceed the MTD from the SAD part of the study to identify the MTD of SYNB1618 within the multiple-dose range studied. Up to 32 healthy subjects may be enrolled in this part of the study. Once the highest MAD cohort and the SAD PKU cohort have been completed, a multiple-dose cohort of male and female subjects (>18 years old) previously diagnosed with PKU will be evaluated. Up to 20 subjects with PKU may be enrolled in the MAD PKU cohort (12 treated: 8 placebo).

A single or multiple oral dose of SYNB1618 in a chilled buffered solution
A single (Part 1) or multiple (Part 2) ascending oral dose of SYNB1618 in a buffered solution. In Part 1, subjects receive one dose of SYNB1618 on Day 1. In Part 2, subjects receive SYNB1618 TID for 7 days.
Placebo Comparator: Placebo
A single or multiple oral dose of placebo (100mL of a chilled buffer solution)
A single (Part 1) or multiple (Part 2) oral dose of a buffered 100mL solution. In Part 1, subjects receive one dose of buffered solution on Day 1. In Part 2, subjects receive a buffered solution TID for 7 days.
- Incidence of treatment-emergent Adverse Events [ Time Frame: Up to 90 days following enrollment. ]Will be measured by assessing nature and frequency of Adverse Events.
