A Phase III, Randomized, Double-Blind, Placebo-Controlled, Efficacy, and Safety Study of Balovaptan in Adults With Autism Spectrum Disorder With a 2-Year Open-Label Extension

This study will evaluate the efficacy, safety, and pharmacokinetics of 10 mg of oral
administration balovaptan once a day (QD) compared with matching placebo in adults (18 years
and older) with autism spectrum disorder (ASD).


Inclusion Criteria:

- Subject has an appropriate study partner, in the opinion of the investigator

- For women of childbearing potential: agreement to remain abstinent or use a
contraceptive method with a failure rate of <1% per year during the treatment period
and for at least 28 days after the last dose of study drug

- Treatment with permitted medications (at a stable dose for 12 weeks before screening)
and behavioral therapy regimens (regimens stable for 6 weeks before screening), with
the intent that such treatments remain stable throughout the study and with no
expected changes before the Week 24 visit

Exclusion Criteria:

- Pregnancy or breastfeeding, or intention to become pregnant during the study

- Previous initiation of new or major change in psychosocial intervention within 6 weeks
prior to screening

(HCV) antibody, or human immunodeficiency virus (HIV) 1 or 2
