Long-term Antipsychotic Pediatric Safety Trial

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Main LAP01 study: The purpose is to evaluate the long-term pathologic weight changes associated with multi-year risperidone or aripiprazole therapy in 3 - \<18-year-old children, who have varying durations of prior antipsychotic drug exposure from the start of study Month 0 (M0). This is critical because children appear to have greater vulnerability to antipsychotic-associated weight gain than adults, and obesity has significant effects on morbidity and mortality. An additional sub-study (registry sub-study) was added via a protocol amendment. This registry sub-study is optional for participants and only participants who participate in the main study are eligible if they were 6 to less than 18 years of age at the time of the M0 visit. Participants who consent to this registry sub-study will participate in yearly in-person visits and complete monthly assessments remotely over the course of two additional years from the time of their final visit of the main LAP01 study.
