NCT ID NCT07187947
First seen Jun 26, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study will follow 500 transgender adults who have been on gender-affirming hormone therapy for at least a year. Researchers will measure changes in blood pressure, cholesterol, body composition, and other heart health markers. The goal is to understand the long-term cardiovascular effects of hormone therapy and improve care for transgender individuals.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- gender-affirming hormone therapy (estradiol, antiandrogens, or testosterone)
- What this could lead to
- If successful, this study could provide clear data on how hormone therapy affects heart health in transgender individuals, helping doctors tailor safer treatment plans.
- What could go wrong
- This is an observational study, not a treatment trial, so it won't directly test a new drug or cure. Results may take years and could still leave many questions unanswered.
