A Phase 4 interventional study of Aveed Injectable Product and Fortesta in Hypogonadism, Hypogonadism, Male and Hypogonadotropic Hypogonadism, sponsored by Endo Pharmaceuticals. Completed at 35 sites in United States. Open to male participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-03-14.
Sponsored by Endo Pharmaceuticals · Phase 4, Interventional, and Treatment
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.
Exclusion Criteria:
Uses known inhibitors (for example, ketoconazole) or inducers of cytochrome P450 3A (for example, dexamethasone, phenytoin, rifampin, carbamazepine) of cytochrome P450 3A (CYP3A) within 30 days prior to study drug administration and through the end of the study.
Fixed dosage level of 750 milligrams (mg)/3 milliliters (mL) administered by intramuscular injections.
Drug: Aveed Injectable Product
40 mg once daily topical gel administration.
Drug: Fortesta
50 mg once daily topical gel administration.
Drug: Testim

Also known as: Testosterone undecanoate
Testosterone gel administered topically. The daily dose of the study drug will be titrated for each participant, according to approved dosage and administration instructions, until the circulating testosterone concentrations of the participant reaches normal concentrations (300-1000 ng/dL).
