The Drug Product ZYN002 is a transdermal CBD gel. CBD is the primary non-euphoric cannabinoid contained in the Cannabis sativa L. plant. The CBD contained within ZYN002 is a pharmaceutically produced Active Pharmaceutical Ingredient (API) that is chemically identical to the CBD present in Cannabis. ZYN002 is currently being evaluated in clinical trials in children and adolescents with Fragile X Syndrome (FXS), autism spectrum disorder, 22q11.2 deletion syndrome, and developmental and epileptic encephalopathies. The present protocol for ZYN2-CL-031 (INSPIRE) is designed to evaluate the safety and tolerability of ZYN002 in the treatment of 11q11.2 Deletion Syndrome. Enrolled participants will be treated for a 1-14 week period and then further evaluated for continuation. Those eligible will be able to continue in the open-label study for an additional 24 weeks of treatment.
