Healthy Clinical Trial - Oxytocin Effects on Self Versus Other Touch

Status Recruiting

Clinical Trial Summary

The main aim of the study is to investigate the modulatory effects of oxytocin (24IU) administered orally using medicated lollipops on the behavioral and neural responses to touching yourself compared with being touched by others.

Clinical Trial Description

In a double-blind placebo-controlled within-subject experimental design, 40 adult male subjects will be randomly allocated to either receive oral oxytocin (24IU, medicated lollipop) or placebo (lollipop without oxytocin). Starting 45 minutes after treatment a resting state functional magnetic resonance imaging (fMRI) will be recorded (8min) and next subjects will be applied two different types of stroking touch (self- vs. other-produced touch) to their left arm repeated in 16 blocks. After each block of applied touch stimulation, subjects will be required to rate their perceived pleasantness of touch from -4 (extremely unpleasant) to 4 (extremely pleasant). The neural basis of touch processing will be measured via simultaneously acquired fMRI. To control potential confounding effects among subjects, before the experiment all participants will be asked to complete a range of Chinese versions of validated questionnaires on personality, traits, attitude towards interpersonal touch and interoceptive ability: Autism Spectrum Quotient (ASQ), Beck Depression Inventory II (BDI), State-Trait Anxiety Inventory (STAI), Social Touch Questionnaire (STQ),Sensory Over-Responsivity (SensOR) Scales, Interpersonal Reactivity Index (C-IRI), Self-Concept Clarity Scale (SCCS), Interoceptive Confusion Questionnaire(ICQ) and Multidimensional Assessment of Interoceptive Awareness(MAIA) scale. Additionally, to control for potential confounding effects of treatment on mood across the experiment, the Positive and Negative Affect Schedule (PANAS) will be administered immediately before and 30 minutes after the treatment. Participants will also complete the PANAS after the touch stimulations to further measure the modulatory effects of touch on mood. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
