Participant Flow

79 subjects were randomized into the study per IVRS. 63 subjects received at least one dose of SYN-010. 16/79 subjects were not administered a single dose of study drug or placebo. We considered the subject truly randomized once the subject had completed the breath methane test, completed the daily diary entries, and were assigned study drug.

PRIMARY outcome

Timeframe: 7 days

Population: 79 subjects consented/randomized to treatment. 63 dosed subjects. 59 subjects (21, 20 \& 18 for the placebo, 21mg and 42mg, respectively) were included for the analysis of AUC on Day 7, and the subjects with missing CH4 values at either baseline or Day 7 were excluded from the analysis since the area under the curve could not be calculated.
