Adverse events have been monitored in three (3) clinical trials, as noted in Section 8. In the GLOW pivotal trial, during the 24-week assessment period, the overall incidence of adverse events in the Plenity treatment group was no different than placebo (71% in both groups). In both treatment groups, most (>95%) adverse events were assessed by the investigator as mild or moderate in intensity. There were no serious adverse events (SAEs) in the Plenity treatment group, whereas there was one (1) SAE in the placebo treatment group. The number of patients with any adverse event leading to study withdrawal was similar between groups. No deaths occurred during the trial.
