About this study

Official title: Characterization of Potential Biomarkers to Assess Brain Connectivity in Neurodevelopmental Disorders in Response to Treatment

The purpose of the proposed research is to study the potential changes in biomarkers of patients with neurodevelopmental disorders in response to treatment in clinical trials or in private psychiatry practice utilizing non-invasive psychophysiological measurements. The investigators plan to obtain psychophysical measurements throughout several periods of treatment.

Read the detailed description

This study will employ a non-invasive custom-built four-point vertical displacement stimulator. This is used to deliver sinusoidal vibrations at very low amplitudes (0-400 microns) to the tips of the fingers. The forearm of the subject rests on the stimulator, the finger tips are vibrated, and the subject answers questions prompted by a computer monitor about their perception of the stimuli. Research staff may explain questions and prompts in a way that may be better understood by the subjects if the subjects experience any difficulty.

This device will be used to obtain objective psychophysical measurements as subjects undergo treatment. The investigators hope that this study will eventually assist in the long term goal of studying ways to develop diagnostic methods, based on changes in cortical information processing capabilities that occur with neurodevelopmental disorders. This would enable clinicians to more objectively determine prognosis and the best course of intervention for their patients.

This study will consent up to 60 subjects who are have initiated or changed pharmacologic treatment as either a participant in a clinical trial or as a private patient of one of the study doctors. Subjects who are a participant in another clinical trial may be one an active medication or a non-active medication(placebo). Subjects will have 7 visits in this study (w0 prior to initiating new treatment, and 4,8, 26 52,78 and 104 weeks after starting the the new treatment. The latter visits may occur either while the individual is taking the medication or after the individual has stopped treatment (in order to assess persistence of treatment-related changes).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT01364818
Study groupRoleWhat they receive
Placebo Comparator: PlaceboNo treatment/ performance of somatosensory task (cortical metrics) without any intervention. The somatosory task will be performed before any intervention/at the midpoint/ and finally at the end.
Active Comparator: Active MedicationTreatment (memantine, lurasidone)/ performance of somatosensory task (cortical metrics) with intervention. The somatosory task will be performed before any intervention has started/at the midpoint/ and finally at the end.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pre-Post Treatment Differences between Groups

    The primary analyses will examine whether the pre-post treatment difference in the effect of confounding stimuli (eg. ratio of confounded stimuli/control stimuli) on amplitude discrimination varies between the two groups (active treatment, no active treatment group) using an unpaired t test.

    Measured: Subjects' V1 occurs within 2 wks of start of tx, V2 within 2 wks of tx midpt, V3 within 1 wk of end of tx. V4 will occur at Mo. 6, V5 will occur at Mo. 12, V6 will occur at Mo. 18, V7 will occur at Mo. 24/End of Study.

Questions about this trial

What is this clinical trial studying?

An observational study of Autism Spectrum Disorders and Psychosis, run by University of North Carolina, Chapel Hill at 1 site 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 3 inclusion and 1 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 18 Apr 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

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?

Pre-Post Treatment Differences between Groups (time frame: Subjects' V1 occurs within 2 wks of start of tx, V2 within 2 wks of tx midpt, V3 within 1 wk of end of tx. V4 will occur at Mo. 6, V5 will occur at Mo. 12, V6 will occur at Mo. 18, V7 will occur at Mo. 24/End of Study.). 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 18 Apr 2016.
