Nineteen participants were randomized to receive AV-101 and placebo in a double-blind crossover design. The primary clinical depression endpoint was not statistically significant at the reported time points; for example, the day-0 comparison was 20.22 with AV-101 versus 20.56 with placebo (p=0.68), and the day-13 comparison was 21.52 versus 19.69 (p=0.26).
