About clinical studies

Every year, thousands of adults and children take part in clinical studies (also known as "clinical trials"). These are scientific studies that help us make medicine better. Studies like this one compare different dosing plans to help us answer specific questions about potential new treatments.

Each study must be reviewed and approved by regulatory boards before it can begin. It is the job of these boards to protect the safety and rights of a study’s participants.

About the aViation study

In brief

People with autism spectrum disorder (ASD) often suffer from secondary conditions too (such as sleeping problems, anxiety and attention issues). Although there are medications available to help manage such secondary conditions, we’re yet to find any that address the social and communication skill issues at the heart of autism. That’s why we’re looking for 300 children and adolescents (aged 5 to 17) with "high-functioning" (for this study, that means an IQ of at least 70) ASD to join the aViation study. The aViation study will test an investigational drug that blocks a hormone receptor in the brain linked to the control of socialization, stress, anxiety and aggression. Please note: this study is being conducted only in the United States.


Up to 39 weeks in total

Screening period

(3-8 weeks)
We'll check that your son or daughter is a good fit for this study.

Dosing phase

(24 weeks)
We'll assign your son or daughter a study drug (either the investigational study drug or a placebo). They will take this for up to 24 weeks and we'll collect information about its effects.

Follow-up period

(up to 7 weeks)
We'll give your son or daughter two final health checks.


Study drugs will be assigned at random (purely by chance, like the tossing of a coin). Two out of three participants will take daily doses of the investigational drug and the rest will take daily doses of a placebo. The placebo looks like the investigational drug but doesn’t contain any medicine.

Both the investigational drug and the placebo are small tablets that can be swallowed whole or dissolved in liquid. You won’t be told what your son or daughter’s tablets contain and neither will your doctor’s team (except in an emergency).


During the study, your son or daughter will visit a study clinic with you around once every 6 weeks (about 7 times in total). This will allow the study team to assess their:

  • General health
  • Daily living
  • Communications
  • Overall ASD
  • Social skills

In between these clinic visits, a nurse will need to take some additional blood samples. To do this, they’ll either visit you at your home or you’ll be asked to go back to the clinic.

You will also be asked to measure your son or daughter’s body temperature and record it in a diary that we will give you.

The data gathered during both clinic and home visits will help us decide the future of the investigational drug; the same parent or guardian must be present each time and willing to answer questions about their son or daughter’s condition and health.
