Who could benefit from this research

Could help

Adults aged 21 and older with overweight or obesity (BMI 25-40 kg/m2) and moderate to severe obstructive sleep apnea, with or without type 2 diabetes.

Less likely to help

Individuals without obesity-related sleep apnea or who are not candidates for SGLT2 inhibitors may not benefit from this study.

What this research studies

The ADIPOSA study is a two-center clinical trial in overweight or obese adults with moderate to severe obstructive sleep apnea, comparing ertugliflozin 15 mg daily to placebo for six months. It will look at how the drug changes body fat distribution, airway anatomy, and physiologic traits related to sleep apnea, as well as clinical symptoms. The study also explores blood biomarkers of adiposity and fluid balance to understand mechanisms that might link metabolism to sleep apnea. Participants will undergo imaging, physiology testing, and clinical assessments to track changes over time. Results could reveal a new metabolic approach to reducing sleep apnea burden in people with obesity and/or type 2 diabetes.

Why it matters

Potential benefit: If successful, participants could experience improvements in sleep apnea symptoms and related health measures through a metabolic treatment approach.

How similar studies have gone: Previous work suggests metabolic interventions can influence sleep apnea traits, but this specific SGLT2 inhibitor approach is novel in this context and exploratory outcomes are being tested.
