Tesamorelin as an Adjunct to Exercise for Improving Physical Function in HIV (TRIUMPH): a clinical trial protocol.
Editor's note
This is a study protocol, not results — a distinction that governs how to read it. TRIUMPH is a two-site, double-blind randomized trial that will test tesamorelin (a growth hormone-releasing hormone analogue) versus placebo, added to a home-based exercise program, in 100 sedentary older adults (50-80) living with HIV who are frail or at risk and carry excess abdominal fat. Tesamorelin is the intervention, so relevance to our coverage is high, and the design — randomized, placebo-controlled, blinded — is rigorous. But because this is only the trial's blueprint, there are no findings to report: outcomes on physical function, muscle content and quality, quality of life, and mitochondrial function at weeks 24 and 48 are planned, not observed. Tesamorelin's established human evidence sits in HIV-associated visceral fat reduction; extending it to physical function and frailty is a reasonable and novel hypothesis this trial will test. For readers, the value is a forward look at a well-designed study to watch (NCT06554717); no efficacy conclusions can be drawn yet.
Plain-language abstract
This article describes the plan for an upcoming clinical trial called TRIUMPH — it is a study protocol, not results. The trial will test whether tesamorelin, an injectable drug that stimulates the body's own growth-hormone system, can improve physical function when combined with exercise in older adults living with HIV. Researchers will enroll 100 sedentary adults aged 50 to 80 who are frail or at risk of frailty and carry excess belly fat. Participants will be randomly assigned to receive either tesamorelin or a placebo alongside a home-based, partly supervised exercise program for 24 weeks, followed by another 24 weeks of exercising on their own. Neither participants nor researchers will know who gets the real drug (a double-blind design). The team will measure physical function, muscle amount and quality, quality of life, exercise participation, and muscle energy production at 24 and 48 weeks. Because this only lays out how the study will be run, there are no results yet — the findings will come later and could guide future ways to help older adults with HIV stay physically capable.
