Efficacy and Safety APT-1011 in Adolescent Subjects With Eosinophilic Esophagitis (EoE) - A Sub-Study of the FLUTE-2 Trial

This is a randomized, double-blind, placebo-controlled study of APT-1011, followed by an open-label extension (OLE) in adolescents (≥12 to \<18 years) with EoE that will evaluate the efficacy and safety of APT-1011 3 mg administered HS for the induction of response to treatment (histologic and symptomatic) over 12 weeks. At Week 12, subjects may move into the open-label single arm study of APT-1011 3 mg hora somni (HS; at bedtime). All subjects who do not move into the open-label study will return at Week 14 for a 2-week off-treatment follow-up.
