Phentermine/Topiramate in Adolescents With Type 2 Diabetes and Obesity
NCT04881799 · View on ClinicalTrials.gov ↗
Study Summary
As the prevalence of obesity rises in the U.S., so does the incidence of pediatric type 2 diabetes (T2D), which is associated with more aggressive disease progression than in adults. From 2002-2012, the incidence of T2D in youth increased by 7% annually in the U.S. Compared to adults. T2D in adolescents is a much more progressive and recalcitrant disease, characterized by more rapid deterioration of β-cell function and earlier incidence of exogenous insulin dependence and diabetes-related comorbidities. A potential factor that drives the rapid progression of adolescent T2D is obesity (body mass index \[BMI\] \>95th percentile. Effective and safe treatments targeting both obesity and β-cell dysfunction are needed for pediatric T2D. In 2012, the FDA approved the use of Phentermine/Topiramate for the treatment of obesity in adults. This orally-administered medication is available in mid- (phentermine 7.5 mg; topiramate 46 mg) and high- (phentermine 15 mg; topiramate 92 mg) doses, administered once per day. In a meta-analysis, phentermine/topiramate was shown to be one of the most effective obesity medication currently available. A large dose-ranging trial in adults evaluating phentermine and topiramate as monotherapies vs. phentermine/topiramate demonstrated superior efficacy of the combination with an acceptable safety profile. Results from a large phase III clinical trial demonstrated placebo-subtracted weight loss of \>9% with treatment for one year at the top dose. Importantly, a separate trial demonstrated that the treatment effect is durable out to at least two years.41 The most common side effects in these trials were paresthesia, dizziness, dysgeusia, insomnia, constipation, and dry mouth. Improvements were noted in blood pressure, lipids, glucose, insulin, HOMA-IR, C-reactive protein, and adiponectin.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04881799
The ClinicalTrials.gov registry entry for NCT04881799 describes a study currently listed as active not recruiting. It is categorized as Early Phase 1, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 13 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Minnesota, which has 919 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Pediatric Obesity appearing as the primary indexed condition, and to 2 interventions — of which Placebo is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04881799 reports 1 study location spanning 1 distinct geographic area — top geographies include Minnesota. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
