Trial Outcomes & Findings for Oxytocin Administration in BDD and OCD (NCT NCT02671266)
NCT ID: NCT02671266
Last Updated: 2018-11-23
Results Overview
This questionnaire includes 48 items for 2 conditions- a self-referent and other-referent condition. Scores are reported for each condition (self-referent or other-referent) reflecting the number of correct responses. Scores range from 0 (least accurate) to 24 (most accurate) for each condition of the questionnaire.

Oxytocin, Then Placebo
Participants will first receive a nasal spray containing the hormone oxytocin (24 IU, 3 puffs per nostril). After a one-week washout period, participants will come back to the clinic and receive a placebo nasal spray (containing all of the same ingredients as the oxytocin spray minus the active oxytocin ingredient).
Oxytocin: Oxytocin nasal sprays will be self-administered in the presence of a study nurse. The dose is 24 IU (3 puffs per nostril, 4 IU per puff) of Syntocinon nasal spray.
Placebo: Placebo nasal sprays will be self-administered in the presence of a study nurse. The sprays will contain all of the same ingredients as the Syntocinon spray minus the active oxytocin ingredient.
|
Placebo, Then Oxytocin
Participants will first receive a placebo nasal spray containing a matching formulation as the oxytocin spray (without the active oxytocin ingredient). After a one-week washout period, participants will come back to the clinic and receive an oxytocin nasal spray (24 IU, 3 puffs per nostril).
Oxytocin: Oxytocin nasal sprays will be self-administered in the presence of a study nurse. The dose is 24 IU (3 puffs per nostril, 4 IU per puff) of Syntocinon nasal spray.
Placebo: Placebo nasal sprays will be self-administered in the presence of a study nurse. The sprays will contain all of the same ingredients as the Syntocinon spray minus the active oxytocin ingredient.

PRIMARY outcome
Timeframe: 45 minutes post nasal spray administrationPopulation: Data reported for BDD and healthy control participants who completed at least one drug visit. There was one patient in the oxytocin first arm who did not complete second placebo drug visit. OCD group was excluded from analyses due to difficulties with recruitment.
This questionnaire includes 48 items for 2 conditions- a self-referent and other-referent condition. Scores are reported for each condition (self-referent or other-referent) reflecting the number of correct responses. Scores range from 0 (least accurate) to 24 (most accurate) for each condition of the questionnaire.

SECONDARY outcome
Timeframe: At least 45 minutes post nasal spray administrationPopulation: One participant (who received oxytocin first) misunderstood the IQ so was excluded from analysis. One subject who received oxytocin first missed the second placebo drug visit. Another subject who received placebo first accidentally did not receive the Interpretation Questionnaire due to administration error. OCD group was excluded from analysis.
This questionnaire includes 33 ambiguous scenarios, representing 3 conditions: BDD threat scenarios, social anxiety threat scenarios, and general threat scenarios. Each item involves 3 possible thoughts that may come to mind in the scenarios which reflect positive, negative, and neutral interpretations. Participants will be asked to rate the likelihood of having each of the thoughts on a scale of 0 (very unlikely) to 4 (very likely). Total scores are reported for negative threat interpretations for each of the 3 conditions (BDD threat, social anxiety threat, general threat), with scores ranging from 0 (very unlikely) to 44 (very likely).

SECONDARY outcome
Timeframe: At least 45 minutes post nasal spray administrationPopulation: Data reported for BDD and HC participants who completed at least one drug visit. One HC patient in the oxytocin first arm did not complete second placebo visit. Another HC patient in the placebo first arm had missing data from the placebo visit due to administrative error. OCD group was excluded from analyses due to difficulties with recruitment.
The outcome measures are response latencies (in milliseconds) on engagement and disengagement trials for disgust, happy, and neutral cue types. Longer response latencies reflect more sustained attention.

SECONDARY outcome
Timeframe: At least 45 minutes post nasal spray administrationPopulation: Sample includes BDD and healthy control participants who completed at least one drug visit. OCD group was excluded from analysis due to difficulties with recruitment.
Participants will have the decision of sending between 0 to 10 game dollars to another participant, without any expectation of monetary return. This initial investment amount will serve as a measure of trust, with a transfer of 0 game dollars indicating no trust and a transfer of 10 game dollars indicating maximum trust.

Oxytocin, Then Placebo
n=17 Participants
Participants will first receive a nasal spray containing the hormone oxytocin (24 IU, 3 puffs per nostril). After a one-week washout period, participants will come back to the clinic and receive a placebo nasal spray (containing all of the same ingredients as the oxytocin spray minus the active oxytocin ingredient).
Oxytocin: Oxytocin nasal sprays will be self-administered in the presence of a study nurse. The dose is 24 IU (3 puffs per nostril, 4 IU per puff) of Syntocinon nasal spray.
Placebo: Placebo nasal sprays will be self-administered in the presence of a study nurse. The sprays will contain all of the same ingredients as the Syntocinon spray minus the active oxytocin ingredient.

Oxytocin
n=34 participants at risk
Participants will first receive a nasal spray containing the hormone oxytocin (24 IU, 3 puffs per nostril). After a one-week washout period, participants will come back to the clinic and receive a placebo nasal spray (containing all of the same ingredients as the oxytocin spray minus the active oxytocin ingredient).
Oxytocin: Oxytocin nasal sprays will be self-administered in the presence of a study nurse. The dose is 24 IU (3 puffs per nostril, 4 IU per puff) of Syntocinon nasal spray.
|
Placebo
n=33 participants at risk
Participants will first receive a placebo nasal spray containing a matching formulation as the oxytocin spray (without the active oxytocin ingredient). After a one-week washout period, participants will come back to the clinic and receive an oxytocin nasal spray (24 IU, 3 puffs per nostril).
Placebo: Placebo nasal sprays will be self-administered in the presence of a study nurse. The sprays will contain all of the same ingredients as the Syntocinon spray minus the active oxytocin ingredient.
