    Study of the Effects of Oxytocin on Attentional Bias and Startle in PTSD

    NCT03211013

    10 Jul 2017 to 9 Jun 2021

Registry summary

Text and fields below are the sponsor's entries at ClinicalTrials.gov, shown as posted.

The investigators will test whether intranasal oxytocin (24 IU vs placebo) will induce effects on attention bias and startle comparable to those the investigators have shown to be induced by the presence (vs absence) of a service dog in Veterans diagnosed with PTSD. This possibility is suggested by a 2015 study showing that urinary oxytocin levels are elevated in association with mutual gaze between dogs and their owners.

Interventions

  • OxytocinDrug
  • PlacebosDrug

Arms2

  • Experimental

    Immediate Oxytocin

    Participants randomly assigned to this arm will receive OT nasal spray (24 IU) at laboratory visit 1 and placebo nasal spray at visit 2. The order will be masked for participants and study staff.

  • Placebo comparator

    Delayed Oxytocin

    Participants randomly assigned to this arm will receive placebo nasal spray at laboratory visit 1 and OT nasal spray (24 IU) at visit 2. The order will be masked for participants and study staff.

Primary outcomes2

Outcomes the sponsor listed as primary.

  1. Change in attentional bias

    Time frame · 1-2 weeks

    Registry description

    Changes between oxytocin vs. placebo lab sessions in the asymmetric allocation of visual attention to one or another of a pair of visual stimuli presented simultaneously as quantified by gaze tracking

  2. Change in startle response -heart rate

    Time frame · 1-2 weeks

    Registry description

    Difference between oxytocin vs. placebo lab sessions in the magnitude of pre-to-post startle stimulus change in heart rate
