About this study

This study is a NIMH-funded multi-site clinical trial that includes UCLA as the coordinating site, with Emory University and Seattle Children's Hospital, as other recruiting sites, and the Nathan Kline Institute as the Data Management Center. The purpose of the study is to examine the effects of an investigational drug, AZD7325, as a potential treatment for high-functioning adults 18 -35 years old with Autism Spectrum Disorders (ASD). The primary study measures are effects on brain waves as measured by non-invasive brain wave recordings (electroencephalograms or EEGs), assessments of side effects, and measures of attention and learning.

The study drug, AZD7325, is manufactured by Astra Zeneca, and was initially tested as a medication for anxiety disorders in over 488 subjects, but was not pursued for marketing due to too few benefits for anxiety. AZD7325 was found to have a very good safety profile and was tolerated by the majority of subjects. AZD7325 has some similar actions to currently marketed anxiety drugs in the benzodiazepine class, but lacks the sedative and negative effects on attention of the benzodiazepines. The study drug is designed to target the GABA neurotransmitter system which is believed to be abnormal in this population.

There are 2 study phases. Phase 1 includes the recruitment of 24 healthy volunteers without mental disorder (6 per site) in order to establish normal EEG reference ranges. Controls will only be seen for one study visit which includes a clinical evaluation, physical exam, routine blood tests, and an EEG. Once control recruitment is complete, Phase 2 will begin.

Phase 2 involves the recruitment of 40 adults (10 per site) 18 - 35 years old with a diagnosis of ASD, normal intelligence, and specific EEG patterns compared to control values. Screening for eligibility will be performed in one visit, which includes a clinical evaluation, tests of learning and intelligence, blood and urine tests, and an EEG. Those subjects who are found to be eligible will be enrolled in a 6-week medication study. Subjects with ASD who are enrolled will be randomly assigned to receive the study drug AZD7325 or placebo in matching capsules. Subjects will be seen weekly by study physicians and clincians for the 7 study visits, including 3 additional EEG recordings, and then for a final follow-up visit (9 total visits including screening lasting up to 11 weeks to complete). Study physicians can adjust the dose of study medication to reduce any side effects.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing AZD7325 in people with Autism Spectrum Disorder, run by University of California, Los Angeles at 3 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 8 inclusion and 12 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 22 Oct 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

EEG (time frame: week 6). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 22 Oct 2015.
