Participant Flow

Study consists of 2 phases, the Placebo-controlled (PC) phase and the Placebo-free (PF) extension phase. Participants were randomized in a 1:1:2:2 ratio into 4 groups: Placebo for 4 wk PC phase followed by either 2.5g or 5.0g BID for 20 wk PF phase or SBI 2.5g or 5.0g BID for 4-wk PC phase followed by 2.5g or 5.0g for 20 wk PF phase.
