Surgical Intervention for Morbidly Obese Adolescents
A Phase 3 study testing Surgery in people with Obesity and Diabetes, run by Göteborg University at 4 sites in Sweden.
Trial summary
The purpose is to study whether the positive effects from obesity surgery in adults also can be achieved when adolescent subjects are operated. Our hypothesis is that the effects concerning weight loss, health improvement and improved quality of life will be as good in adolescents as in adults. Read more about this study

About this study
Official title: Surgical Intervention With Laparoscopic Roux-en-Y Gastric Bypass for Morbid Obesity in Adolescence - a Matched Control Study
The purpose is to study whether the positive effects from obesity surgery in adults also can be achieved when adolescent subjects are operated.
Our hypothesis is that the effects concerning weight loss, health improvement and improved quality of life will be as good in adolescents as in adults.
Read the detailed description
Severe obesity in the adolescence is a major concern since there is a constant rise in prevalence worldwide. There is a need of effective tools to treat those patients since the natural course with conservative treatment is very pessimistic. I. e. most of the subjects having a BMI >40kg/m2 in the adolescence will remain morbidly obese also in their adult life.
The three largest centres in Sweden treating obese children (Stockholm, Gothenburg and Malmö) will offer patients fulfilling the inclusion criteria to be operated with laparoscopic gastric bypass. If not willing to be operated they could join the study as a control case.
Subjects will be investigated at the baseline concerning physical health status and existence of medical risk factors but also regarding their quality of life, eating habits and physical activity. They will subsequently be follow over a ten year period regarding these variables.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Surgery in people with Obesity and Diabetes, run by Göteborg University at 4 sites in Sweden.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 2 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites in Sweden. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
BMI development (time frame: 10 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00289705, which also lists 5 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Feb 2017.
