Additional Study Information: This study will examine the possible benefits of an investigational drug called ML-004 in adolescents and adults diagnosed with autism spectrum disorder (ASD). We are currently recruiting adolescent participants (12-17 years). Participation will involve ten visits to the Center for Autism and the Developing Brain in White Plains, NY over a period of 26 weeks. This will allow the study team to assess participants' general health, perform developmental testing and provide study related medical care. Participants will not have to pay for any study related treatments, lab tests or assessments. Participants and Study Partners will receive $100 each in reimbursements for in-clinic study visits and up to $40 in travel reimbursements.
