Brief Summary
Suramin has been found to correct the symptoms, metabolism, and brain synaptic abnormalities in two classical genetic and environmental mouse models of autism. A preliminary clinical trial (SAT-1) examined the safety and activity of a single low-dose of suramin in children with ASD and concluded suramin showed promise as a novel approach to treatment of ASD. The current study, STAT-2A, will be a randomized, double-blind, crossover, 30-week study to evaluate the preliminary proof of concept, safety, and PK of suramin sodium (KZ101) with repeat dosing by IV infusion in males 5-14 years of age who have been diagnosed with ASD. The study will be conducted at approximately 3 sites contributing approximately 15 subjects per site. Total enrollment of approximately 45 subjects is planned to achieve approximately 36 participants completing the study.
