Change in Dietary Intake
The adolescent/young adult will complete a dietary record on 3 consecutive days (2 weekdays, 1 weekend day) based on standardized protocols for dietary assessment. Total caloric intake, macronutrient, and micronutrient breakdown will be assessed.
Change in Hunger
The adolescent/young adult will report hunger before each meal and snack for 24 hours using a 100mm visual analogue scale (0= no hunger, 100 = most hunger)
Change in Satiety
The adolescent/young adult will report satiety before each meal and snack for 24 hours using a 100mm visual analogue scale (0= no fullness, 100= most full)
Change in Eating in the Absence of Hunger
Validated questionnaire: Eating in the Absence of Hunger-Parent (EAH-P) completed by the parent/guardian about their adolescent/young adult. This measure has 14 items. Each item is on a 5-point Likert scale ranging from 1= "never" to 5= "always". A higher score indicates more eating in the absence of hunger. Total and sub scales are calculated by taking the average of the items. Total score measures the overall construct "Eating in the Absence of Hunger" Subscales include: "External Cues" (4 items); "Response to negative affect" (6 items); "Fatigue/Boredom" (4 items).
Change in Cognitive Restraint, Disinhibited Eating, and Predisposition to Hunger
The "Three-Factor Eating Questionnaire" will be completed by the adolescent/young adult. This is a 51-item measure that is divided into 2 parts, and assesses 3 eating behaviors: 1) Cognitive Dietary Restraint (20 items), 2) Disinhibited Eating (16 items), and 3) Predisposition to hunger (15 items). Higher scores in each domain indicate more of each of those behaviors. The minimum score for factors 1, 2, and 3 are: 0, 0, and 0. The maximum score for factors 1, 2, and 3 are: 20, 16, and 15 Part I includes items 1-36 rated as either True (1) or False (0) Part II includes items 37-51 and is rated on a 4-point Likert-like scale with one exception- item 50 is rated on a 6-point scale. Scores for each of the three eating behaviors are calculated by taking the average of the items, and are most commonly reported separately, not as a total score.
Change in Weight Related Quality of Life- Adolescent
"Impact of Weight on Quality of Life-Kids" questionnaire will be completed by the adolescents age <=19. Total and each of the 4 sub scales (Physical Comfort-6 items, Body Esteem-9 items, Social Life-6 items, and Family Relations-6 items) range from a minimum score of 0 to a maximum of 100. Higher scores indicate higher quality of life.
Change in Weight Related Quality of Life- Parent
"Impact of Weight on Quality of Life-Kids Parent Proxy" questionnaire will be completed by the parent of the adolescent/young adult. Total and each of the 4 sub scales (Physical Comfort-6 items, Body Esteem-9 items, Social Life-6 items, and Family Relations-6 items) range from a minimum score of 0 to a maximum of 100. Higher scores indicate higher quality of life.
Change in Weight Related Quality of Life- Young adult
"Impact of Weight on Quality of Life-Lite" questionnaire will be completed by the young adult age >=20. Total and each of the 5 sub scales (Physical function-11 items, Self Esteem-7 items, Sexual Life-4 items, Public distress-5 items, and Work-4 items) range from a minimum score of 0 to a maximum of 100. Higher scores indicate higher quality of life.
Change in General Health Related Quality of Life: PedsQL instrument
PedsQL instrument will be completed by the adolescent/young adult. There are 4 scales: Physical Functioning (8 items), Emotional Functioning (5 items), Social Functioning (5 items), and School Functioning (5 items) and 3 Summary Scores: Total Scale Score (23 items), Physical Health Summary Score (8 items), and Psychosocial Health Summary Score (15 items). Items are rated on a 0-4 scale. Items are reverse scored and linearly transformed to a 0-100 scale, such that 0=100, 1=75, 2=50, 3=25, and 4=0. Higher scores indicated better health-related quality of life. Scale Scores are calculated as the sum of the items over the number of items answered. Psychosocial Health Summary Score is calculated as the sum of the items over the number of items answered in the Emotional, Social, and School Functioning Scales. Physical Health Summary Score is the same as the Physical Functioning Scale Score.
Change in Depression
The adolescent/young adult will complete the 20-item Center for Epidemiologic Studies Depression Scale (CES-D). Each item is rated on a 0 to 3 scale (positive items are reverse scored). Minimum score is 0 and maximum is 60. Higher scores indicate more depressive symptoms. Total score is calculated by summing each of the 20 individual items scores.
Participant Satisfaction: questionnaire
The participating family will be asked to complete a satisfaction questionnaire that will assess reasons for participation, experience during study visits, satisfaction with the effect of the study drug, ease of communication with study staff, and study burden.

5. Study Description

Brief Summary
The goal of this pilot study is to establish the feasibility and initial efficacy of the combination of phentermine and topiramate for adolescents and young adults who require additional risk reduction after bariatric surgery. This study will use a randomized, placebo-controlled, double-blinded design to evaluate an adjunctive 12-week intervention of phentermine + topiramate + standard of care vs. placebos + standard of care 6 months after bariatric surgery, among 12 to 24 year olds who don't achieve expected weight loss or who remain severely obese (n=10 total).
