About this study
Official title: A Double Blind, Randomized, Placebo-Controlled Study of CM-AT for the Treatment of Autism in Children With All Levels of Fecal Chymotrypsin (FCT)
The purpose of this study is to determine whether CM-AT is safe and effective in treating the core symptoms of autism in children with all levels of fecal chymotrypsin.
Read the detailed description
Autism is clearly a significant cause of disability in the pediatric population. Many children with Autism exhibit impaired protein digestion which may or may not manifest in self-restricted diets. The inability to digest protein affects the availability of essential amino acids in the body. CM-AT is designed to enhance protein digestion thereby potentially restoring the pool of essential amino acids. Essential amino acids play a critical role in the expression of several genes important to neurological function and serve as precursors to key neurotransmitters such as serotonin and dopamine. CM-AT is a proprietary enzyme that is designed as a granulated powder taken three times daily.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
CM-ATDrug
Single unit dose powder of active substance (CM-AT) administered 3 times per day for 90 days
PLACEBODrug
Also called placebo powder
Single unit dose powder of non-active substance administered 3 times per day for 90 days
| Study group | Role | What they receive |
|---|---|---|
| CM-AT | Experimental | Active substance in single unit dose powder Receives: Drug: CM-AT |
| Placebo | Placebo comparator | Placebo powder of inactive substance Receives: Drug: PLACEBO |
What is being measured
The primary outcome is the main question the study is designed to answer.
Primary Outcome Measurements to Determine Efficacy of Treatment With CM-AT Versus Placebo for Changes in the Aberrant Behavior Checklist Subscale for Irritability / Agitation (ABC-I) Between Baseline and Week 12/Termination Visit
Primary outcome measurements to determine efficacy of treatment with CM-AT versus Placebo for changes in the Aberrant Behavior Checklist (ABC) - Community sub scale for Irritability/Agitation (ABC-I) between baseline (subject's initial measurement) and Week 12/Termination (subject's final measurement) visit. Participants were between 3 through to 6 years old inclusive and took 900mg CM-AT or Placebo three times daily. The ABC-I is one of five discrete sub scales measured by the ABC. The scale range is 0-45. A higher score reflects higher severity of symptoms (irritability). Scores are obtained via Parent Rated Questionnaire. Parents respond to a series of questions on a scale directly into an electronic data capture system (EDC), responding: 0 = not at all a problem 1 = the behavior is a problem but slight in degree 2 = the problem is moderately serious 3 = the problem is severe in degree. The score was automatically calculated by the EDC.
Measured: Screening through Week 12/Termination
Secondary outcomes (1)
Secondary Outcome Measurements of Changes in the Aberrant Behavior Checklist Checklist Subscale for Lethargy / Social Withdrawal (ABC-L) Between Baseline and Week 12/Termination Visit
Secondary outcome measurements to determine efficacy of treatment with CM-AT versus Placebo for changes in the Aberrant Behavior Checklist- Community (ABC) sub scale for Lethargy / Social Withdrawal (ABC-L) between baseline (subject's initial measurement) and Week 12/Termination (subject's final measurement) visit. Participants were between 3 through to 6 years old inclusive and took 900mg CM-AT or Placebo three times daily. The ABC-L is one of five discrete sub scales measured by the ABC. The scale range is 0-48. A higher score reflects higher severity of symptoms (lethargy). Scores are obtained via Parent Rated Questionnaire.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing CM-AT in people with Autism, run by Curemark at 31 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 24 May 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 31 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 26 Oct 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Primary Outcome Measurements to Determine Efficacy of Treatment With CM-AT Versus Placebo for Changes in the Aberrant Behavior Checklist Subscale for Irritability / Agitation (ABC-I) Between Baseline and Week 12/Termination Visit (time frame: Screening through Week 12/Termination). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02410902, which also lists 29 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 May 2023; AzTrials last refreshed its copy on 7 Nov 2026.
