A Study of the Effect of Testosterone Replacement Therapy on Blood Pressure in Adult Male Participants With Hypogonadism
United States673 participantsStarted 2020-06-30
Plain-language summary
Testosterone is the principal androgen produced by the male testes. Male Hypogonadism is the result of inadequate production of testosterone by the Leydig cells of the testes and is reflected by total serum concentrations of testosterone of \< 300 nanograms (ng)/deciliters (dL), with no discernible diurnal pattern. The etiology of hypogonadism may be primary or secondary. The treatment of males with primary, and in some cases, secondary hypogonadism includes administration of testosterone.
Testim® and Fortesta® are topical gels that when applied daily help to increase the total testosterone levels in the blood through skin absorption. Aveed® is an injectable form of testosterone treatment and participants randomized to this treatment arm will receive 3 injections over the course of 16 weeks.
This study is designed to evaluate the effect on blood pressure of approved testosterone products (Testim®, Fortesta®, and Aveed®) after 16 weeks of therapy using 24-hour ambulatory blood pressure to reveal shifts in blood pressure levels.
