NCT02344108
Obstructive sleep apnea (OSA) affects up to 1% of the general pediatric population and is associated with adverse behavior and quality of life, as well as long term cardiopulmonary system complications. Trisomy 21 (Down Syndrome) is the most common chromosomal disorder, with a incidence of approximately 1 per 660-800 births. Patients with Down Syndrome have a higher incidence of OSA than the general pediatric population, with rates of 30-60%, resulting in increased morbidity and decreased quality of life for affected individuals. In children, adenotonsillectomy (T\&A) is often a contributing factor to OSA, and adenotonsillectomy is a first line treatment. Children with Down Syndrome often undergo T\&A for obstructive sleep apnea, however 30-50% will have persistent obstructive sleep patterns requiring continuous positive pressure airway support (CPAP) or tracheotomy. Persistent obstruction is attributed to anatomic and physiologic differences in this population, including reduced muscular tone, macroglossia, maxillary hypoplasia, and lingual tonsil hypertrophy. This pilot study is designed to determine if the Inspire® Upper Airway Simulation System, Model 3024 IPG, and any subsequent iteration thereof that are approved under P130008 for the treatment of obstructive sleep apnea, which has already been approved for use in adults with OSA, can be safely implanted and used in adolescents and young adults with Down Syndrome.

The study objectives are the following: 1. To evaluate the efficacy of 3 doses of XP23829 compared to placebo for the treatment of moderate-to-severe chronic plaque-type psoriasis. 2. To evaluate the safety and tolerability of XP23829 in subjects with psoriasis. 3. To evaluate the pharmacodynamics (PD) of XP23829 through immunological analysis of peripheral blood samples.
