FAQs

  • What is the purpose of this clinical trial?
    The clinical trial is researching an experimental treatment, AB-2004, that is designed to adsorb specific substances produced by bacteria in the gut and reduce their levels circulating in the bloodstream. Scientific studies have shown that types of bacteria in the gut produce substances that may contribute to certain characteristics, such as irritability, in children with Autism Spectrum Disorder (ASD). The purpose of this study is to learn if the study medication may help improve irritability in children compared to placebo. The study is seeking participants between the ages of 5 and 17 who have been diagnosed with ASD and are experiencing irritability to enroll in this clinical trial. The study aims to show that lowering the levels of these substances can improve irritability in children with ASD.
  • Who is conducting this clinical trial?
    The clinical trial is being conducted on behalf of Axial Therapeutics by by multiple sites (research clinics or hospitals) in the United States, Australia and New Zealand with trained and qualified medical specialists. Axial is a pharmaceutical company dedicated to improving the lives of people with neurological conditions.
  • What is the study medication?
    AB-2004 is an experimental therapy that is being developed as a potential treatment for irritability associated with autism. AB-2004, which is a powder, selectively adsorbs certain substances produced by bacteria in the gut before they enter the bloodstream and reach the brain. It is taken by mouth 3 times per day; is tasteless and odorless; and is mixed with any soft food your child may like such as yogurt or apple sauce. AB-2004 was shown to be safe and well tolerated in a previous study involving adolescents with ASD. AB-2004 is an experimental treatment and not currently approved in the United States, Australia and New Zealand. Eligible participants will be randomly assigned to receive either AB-2004 or placebo.
  • What is a placebo-controlled clinical study?
    The TAPESTRY Study is “placebo-controlled” which indicates that it includes a placebo. There is a chance that the medication your child receives is a placebo, which is a harmless substance that looks identical to the treatment being tested in the clinical trial. Placebos are an important part of clinical research and are used as a control group to compare the real study’s drug effects.
  • Will we have to pay anything to participate?
    No. If you qualify and are chosen to participate, you will receive all study-related care, including the investigational drug and all assessments at no cost to you. Insurance is not required.
  • How many people will participate in this trial?
    The TAPESTRY Autism Study will enroll about 140 participants with autism spectrum disorder at study centers throughout the US.
  • How long will the clinical trial last?
    If your child qualifies, participation in this study will last approximately 14-16 weeks.
  • What if after joining the trial I decide I no longer want my child to participate?
    Like all clinical trials, participation is fully voluntary. Your child may leave the study at any time.
  • Who is responsible for caring for my child’s health during the trial?
    When your child becomes a participant, the study doctor will administer the medication to your child at the clinic and conduct examinations and testing. You will be required to give additional doses of the study medication to their child at home, collect urine and stool samples, and answer questions about your child’s behavior.
  • What precautions are you taking to protect my child from COVID during in-person visits?
