28-Day Daily-dose Crossover Study of the Safety and Tolerability of SB-121 (Lactobacillus Reuteri With Sephadex® and Maltose) in Subjects, Ages 15 to 45 Years, Diagnosed With Autistic Disorder

Summary

SB-121 is being developed for use in the treatment of autistic disorder (AD). This study is a multiple-dose, randomized, double-blind, placebo-controlled, cross-over single-site Phase I study. The primary objective is to evaluate the safety and tolerability of multiple doses of SB-121 in subjects ages 15 to 45 years with AD. Additionally, multiple measures of AD, as well as mechanistic biomarkers, will be assessed in order to inform later stage trials.
