The clinical trial of NB-001 in Children and Adolescents With 22q11 Deletion Syndrome

This is a Phase 2, randomized, placebo-controlled crossover trial to assess the safety and efficacy of NB-001 in children and adolescents with 22q11DS that manifest commonly associated neuropsychiatric conditions.

The trial is designed to allow all visits to be conducted via telephone and/or video (i.e., telemedicine) or by home health nurse. An in-person visit is required at Screening unless site or government mandates restrict this due to coronavirus disease-2019 (COVID-19). Other in-person visit(s) may occur, if indicated, based on the Investigator's clinical judgement. Subjects will be screened to confirm eligibility and then randomized in a 1:1 ratio to one of two treatment sequences: NB-001 (active drug product) followed by placebo (treatment sequence A/P) or placebo followed by NB-001 (treatment sequence P/A). During the Double-Blind Treatment Phase of the trial, the subject and/or parent/legal guardian (henceforth, 'parent/guardian') will be contacted at Day 0 to complete baseline symptom scales and will begin dosing with the investigational product (IP; NB-001 or placebo) on the morning of Day 1. Subjects or their parent/guardian will administer the IP twice daily (BID) and will be contacted at Days 0, 1, 14, 28, 42, 49, 50, 63, 77 and 91 to evaluate measures of safety and efficacy, including the completion of symptom scales. In addition, the subject and/or parent/guardian will be contacted at Days 7, 21, 35, 56, 70 and 84 to assess subject safety.
