The Effects of Oxytocin on Affective Touch

October 26, 2018 updated by: Keith Kendrick, University of Electronic Science and Technology of China

Oxytocin Effects on Neural Processing of Affective Touch and Associations With Trait Autism

The main aim of the study is to investigate whether intranasal oxytocin (24IU) increases the affective processing of touch in general or whether it's effect vary according to the affective valence of the touch (positive, neutral, negative). Moreover, associations with trait autism will be explored.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

A double-blind, within-subject, placebo controlled design will be employed in this study. In a randomized-order a total of 40 healthy male subjects will receive oxytocin- and placebo-nasalspray (interval between the administration > 2 weeks). 45 minutes after treatment subjects will be administered the touch-stimulation to the dorsal forearm by a trained experimenter (lengths: 8cm, rate 8cm/s). After each block of stimulation, the subjects will be asked to rate their subjective experience of the touch.The neural basis of touch processing will be measured via simultaneously acquired fMRI.

Levels of trait autism will be assessed using the Autism Spectrum Quotient (ASQ) and related scales such as the Empathy Quotient (EQ), Liebowitz Social Anxiety Scale (LSAS), or the Sensory over Responsivity Scale (SOR) and Under Responsively Scale (URS).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
brain function: neural activity during affective touch as assessed via BOLD fMRI
Time Frame: 45-90 minutes after treatment administration
fMRI data will be analyzed using a within-subject General Linear Model approach - to determine the effects of oxytocin neural activity following oxytocin administration will be compared with neural activity following placebo administration.
45-90 minutes after treatment administration
Brain function: functional connectivity during affective touch as assessed via BOLD fMRI
Time Frame: 45-90 minutes after treatment administration
fMRI data will be analyzed using a within-subject General Linear Model approach - to determine the effects of oxytocin on the brain network level, functional connectivity following oxytocin administration will be compared with functional connectivity following placebo administration.
45-90 minutes after treatment administration

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
