Trial Outcomes & Findings for Oxytocin Treatment of Opioid Dependence (NCT NCT02548728)

NCT ID: NCT02548728

Last Updated: 2019-08-07

Results Overview

The Clinical Opiate Withdrawal Scale (COWS) is an 11-item, observer-rated tool for quantifying withdrawal symptoms. Each section is rated from 0 (no symptom) to 4 or 5 (most severe symptom). Total score is classified into a 4 point rating scale (mild 5-12, moderate 13-24, moderately severe 25-36 and severe more than 36 points). Lower scores are more favorable.

Measure
Oxytocin
Self administration three times on the first day, then twice daily treatment with intranasal oxytocin spray for 4 days. Intranasal Oxytocin Spray: 10 insufflations (40IU of oxytocin total) given three times on day of enrollment and then twice daily for 4 days
Placebo
Self administration three times on the first day, then twice daily treatment with intranasal spray that does not contain oxytocin for 4 days. Placebo: 10 insufflations (40IU of placebo, same solution as active treatment minus oxytocin) given three times on day of enrollment and then twice daily for 4 day

4.2 Average COWS score * hours
Standard Error 1.5
3.4 Average COWS score * hours
Standard Error 1.5

SECONDARY outcome

Timeframe: 5 days

Population: SOWS data not collected due to subject noncompliance in adhering to form completion.

Least squares mean AUC day 1 pre-dose through Day 5 in SOWS; SOWS scores range from 0-64, with a lower score being more favorable

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Days 1-5, the AUC includes data starting from time 0 hours up to 120 hours post-dose.

Craving levels were measured using the VAS score on Days 1 to 5; the VAS scores range from 0 ("no cravings") to 100 ("most intense craving I have ever had"). Note that the value of AUC is a product of time multiplied by VAS scale score thus the numeric values are higher than the highest value on the scale.

Population: STAI data not collected due to subject noncompliance in adhering to form completion.

The Spielberger State and Trait Anxiety Inventory (STAI) is a validated self-reporting instrument used to assess anxiety in adults. The inventory consists of state anxiety, which evaluates how the subject feels currently (transient anxiety). The State scale consists of 20 questions, each question rated 1-4, and a higher score indicates greater anxiety. Total score ranges from 20 (no anxiety) to 80 (maximum anxiety).
