Trial Outcomes & Findings for Intranasal Oxytocin in Hypothalamic Obesity (NCT NCT02849743)

NCT ID: NCT02849743

Last Updated: 2022-10-05

Results Overview

The primary objective of this study is to determine whether treatment with 8 weeks of intranasal OXT (relative to 8 weeks of placebo) will promote weight loss in children and adolescents with brain tumors and hypothalamic obesity syndrome ages 10 to 35 years. Specifically, the primary outcome will be: the difference of the post-treatment weight between the two periods (treatment vs. placebo); the statistical model will include the difference of the baseline weight between the two periods and the sequence (OXT-PBO versus PBO-OXT).

Participant Flow

Once consent was obtained, participants were reviewed for eligibility and inclusion in the trial. Individuals meeting criteria were randomized. In total, 18 participants signed informed consent and completed in-person screening. 5 of 18 were considered ineligible after screening due to: concomitant medications (2), ECG findings (2), and BMI (1). Intervention Period 1: Week 0 to Week 7, Washout: Week 8 to Week 11, Intervention Period 2: Week 12 to Week 20.

Syntocinon (= Oxytocin), Then Placebo
1. Intranasal oxytocin, administered 3 times per day (at mealtimes) for 8 weeks (dosage based on weight: 16 IU to 24 IU; dose escalation, if appropriate, occurs at 2 weeks) 2. Intranasal placebo, administered 3 times per day (at mealtimes) for 8 weeks (dosage based on weight: 16 IU to 24 IU; dose escalation, if appropriate, occurs at 2 weeks) \*Dose Escalation, as appropriate, at 2 Weeks Syntocinon: The active substance of Syntocinon is a synthetic nonapeptide identical to the posterior pituitary hormone oxytocin. Placebo (for Syntocinon): The placebo is identical to the Syntocinon formulation with the exception of the active compound, i.e., without oxytocin.

PRIMARY outcome

Timeframe: Assessed at the beginning and end of each Intervention Period (Intervention 1: Visit 1 to Visit 4 = 8 Weeks, Intervention 2: Visit 5 to Visit 8 = 8 Weeks)

Population: In order to be included, participants needed data in Intervention 1 (Block 1) and Intervention 2 (Block 2). 10 of 13 Participants with complete data available for analysis.

The primary objective of this study is to determine whether treatment with 8 weeks of intranasal OXT (relative to 8 weeks of placebo) will promote weight loss in children and adolescents with brain tumors and hypothalamic obesity syndrome ages 10 to 35 years. Specifically, the primary outcome will be: the difference of the post-treatment weight between the two periods (treatment vs. placebo); the statistical model will include the difference of the baseline weight between the two periods and the sequence (OXT-PBO versus PBO-OXT).

SECONDARY outcome

Timeframe: Assessed during each treatment block: at either initial lower dose at baseline (week 0 & week 12) or increased dose at 2 weeks (week 2 & week 15); 50% of participants at each set.

Population: In order to be included participants had to have samples collected during both Intervention 1 and Intervention 2. IV Access was not able to be obtained in some individuals. 7 of 13 Participants had data available for analysis. Specimens were collected during the lower dose (Visit 1 or Visit 5) or the higher dose (Visit 2 or Visit 6). As this assessment was only administered once per Intervention, we are not able to calculate/report the change at 8 weeks.

We will determine the immediate peripheral pharmacokinetics of intranasal oxytocin (versus placebo/endogenous oxytocin). In order to minimize participant burden, each participant had the assessment at one time point with either the low or high dose of oxytocin. And at one point during the placebo block. For this exploratory outcome, visits representing lower dose and higher dose oxytocin were Combined versus lower and higher dose placebo.

Measured using the Dykens Hyperphagia Questionnaire. The Dykens Hyperphagia Questionnaire is a 11-item questionnaire with responses on a scale of 1 to 5. 1 = Not a Problem, 5 = Severe or Frequent Problem. The scale includes three domains: hyperphagic behavior, hyperphagic drive, and hyperphagic severity. There is also a total or overall score which is calculated by combining the scores from each domain. Maximum Possible Score: 55, Minimum Possible Score: 11. Higher scores indicated more severe and/or frequent Hyperphagia.

Within Participant Change in Disinhibition of Eating Attributable to Oxytocin vs Placebo. Measured using the Eating Inventory questionnaire. The Eating Inventory consists of 36 statements where participants respond true or false, 14 questions where participants select a response from 1 (least severe: rarely or not at all) to 4 (most severe: always or very much), one final question askes participants to rate their level of restraint in eating from 1 (no restraint) to 6 (constantly limiting food). The scores are assessed in 3 dimensions: Dietary Restraint (Max Score: 21), Disinhibition (Max Score: 16), and Hunger (Max Score: 14). Within Participant Change in Scores from the Disinhibition of Eating dimension are reported.

The National Institute of Neurological Disorders and Stroke (NINDS) quality of life in neurological disorders (Neuro-QoL) scale is a set of self-reported measures to assess health-related quality of life of adults and children. Individuals rate domains on a scale from 1 (Never/Not at all) to 5 (Always/Very Often). Each response is assigned a value. Values are combined for a total raw score, then converted to a T-Scores (cohort-specific mean 50, SD 10). Higher scores on the sub-scale domains indicate more of the entity. Adult and child scores were combined in analyses.

Within Participant Change in Family Assessment Device-General Function Scale (FAD-GFS) Attributable to Oxytocin vs Placebo. The Family Assessment Device (FAD-GFS) includes 12 statements where individuals select from a scale of 4 responses ranging from Strongly Agree (SA) to Strongly Disagree (SD). Each response has a score ranging from 1 to 4, some of the items are reverse scored (i.e. 1 = 4, 2 = 3, 3 = 2, 4 = 1). Minimum Total Score: 12, Maximum Total Score: 48. The scores for each question are added and then divided by the total number of questions. The Minimum Overall Score: 1, Maximum Overall Score: 4. A score of 2 or above is considered dysfunction.

OTHER_PRE_SPECIFIED outcome

Timeframe: Assessed using data from Intervention 1: Screening and Visit 4 (Week 8) and Intervention 2: Visit 5 (Week 12) and Visit 8 (Week 20)

Population: In order to be included, participants had to have data in Intervention 1 and Intervention 2. 10 of 13 Participants had data available for analysis.

Measured using the Bone Mineral Density in Childhood Study (BMDCS) physical activity questionnaire. The Bone Mineral Density in Childhood Study (BMDCS) questionnaire captures the amount of time spent in physical activity. The assessment asks participants to record the number of hours spent in different categories of physical activity (Min: 0 hours per week, Max: 11+ hours per week).

Measure
Syntocinon (Intranasal Oxytocin)
n=12 participants at risk
1\) Intranasal oxytocin, administered 3 times per day (at mealtimes) for 8 weeks (dosage based on weight: 16 IU to 24 IU; dose escalation, if appropriate, occurs at 2 weeks) Syntocinon: The active substance of Syntocinon is a synthetic nonapeptide identical to the posterior pituitary hormone oxytocin.
Placebo
n=12 participants at risk
1\) Intranasal placebo, administered 3 times per day (at mealtimes) for 8 weeks (dosage based on weight: 16 IU to 24 IU; dose escalation, if appropriate, occurs at 2 weeks) Placebo (for Syntocinon): The placebo is identical to the Syntocinon formulation with the exception of the active compound, i.e., without oxytocin.
