Starting a Testosterone and Exercise Program After Hip Injury
This study is a randomized controlled double-blinded multi-center clinical trial enrolling female hip fracture patients who are 65 and older. It will compare the effects of six months of supervised exercise training combined with daily topical testosterone gel, to six months of supervised exercise and inactive gel, and to Enhanced Usual Care. One third of the participants will receive topical testosterone gel and a supervised exercise training program; one third will receive topical inactive gel and a supervised exercise training program; one third will receive a home exercise program. All participants will receive nutritional counseling, and calcium and vitamin D supplements.

Hip fractures are common among older women and can have a devastating impact on their ability to remain independent. A clinically important functional decline and failure to recover following a hip fracture has been documented as late as a year after the fracture, even among women who were functioning at high levels before the event. Age-associated androgen deficiency in women contributes to deficits in muscle mass, strength and power that are common in this patient population before the fracture, and are exacerbated afterward. A pilot study of testosterone (T) supplementation in elderly female hip fracture patients has demonstrated the feasibility of T treatment in this population, and showed gains in lean body mass (LBM) and muscle strength with active drug, compared to placebo. The benefits of exercise in restoring muscle strength and physical function after a hip fracture have been documented. However, it remains unclear whether T treatment can augment the effects of exercise on mobility and patient-reported function after hip fracture.
The STEP-HI study is a 3-group, multi-center, randomized, placebo-controlled, double-blinded, parallel group clinical trial in older female hip fracture patients. 300 female hip fracture patients, age 65 years and older, will be enrolled from 6 clinical sites, using objective screening criteria for T deficiency (serum total testosterone level < 40 ng/dL) and physical frailty (Modified Physical Performance Test (PPT) Score of 12-28). The trial will compare the effects of Enhanced Usual Care with home exercises and no gel treatment (EUC), supervised exercise training (EX) with inactive (placebo) gel (EX+P), and EX combined with T therapy (EX+T), to ascertain the incremental impact of adding T to EX in older adult women with a recent hip fracture. The study team will carefully monitor testosterone levels, adverse events, biochemical parameters, and factors related to adherence to the interventions.
Information from this study has the potential to alter treatment of hip fracture in older women, a problem that contributes to significant morbidity and mortality, and has a large public health impact. The STEP-HI study is highly aligned with NIA's mission of identifying interventions that target common geriatric conditions and improve treatment options for older adults with multiple morbidities or risk factors.
