Safety Outcomes from a Long-Term, Prospective Study of Sertraline Use in Children and Adolescents: The Sertraline Pediatric Registry for the Evaluation of Safety

<b><i>Objectives:</i></b> To describe the Sertraline Pediatric Registry for the Evaluation of Safety (SPRITES) safety results, including adverse events (AEs) (serious and nonserious, including suicide-related events) following long-term treatment with sertraline in children and adolescents aged 6-16 years. <b><i>Methods:</i></b> SPRITES was a multicenter, prospective, observational study designed to compare cognitive, emotional, and physical development in pediatric patients exposed to sertraline or psychotherapy alone in routine care for up to 3 years. Safety outcomes included AEs collected on the Pediatric Adverse Event Rating Scale and suicidal ideation/behavior (SIB), as assessed by the Columbia-Suicide Severity Rating Scale (C-SSRS). AEs (unadjusted and adjusted for exposure) and C-SSRS data were summarized descriptively, and a marginal structural model (MSM) was applied to the C-SSRS results. <b><i>Results:</i></b> Between April 2012 and September 2020, 941 patients participated in SPRITES. At baseline, per treating physician discretion, 695 patients were administered sertraline, 243 patients were administered psychotherapy alone, and 3 patients were administered an antidepressant other than sertraline. At postbaseline timepoints, patients receiving sertraline reported higher overall rates of AEs relative to the other antidepressants and nonpharmacologic treatment groups. The most common AEs in the sertraline group were related to psychiatric and gastrointestinal disorders. In all exposure groups, the incidence of AEs and SIB decreased across study timepoints. MSM analyses did not demonstrate an effect of sertraline treatment on new onset or worsening SIB. <b><i>Conclusion:</i></b> The safety profile of sertraline in a long-term, real-world setting is similar to that of prior pediatric sertraline studies. A greater proportion of AEs and SIB events reported in the sertraline group compared with the nonpharmacologic therapy group is not unexpected given the safety profile of sertraline and observation of baseline differences in psychiatric disease severity between exposure groups. With prolonged sertraline treatment, incidence rates of AEs and SIB events decreased, and worsening of SIB was not observed.
