Filter by:After the age of 40, there is a gradual decline in the production of testosterone. Among obese men, the decline in testosterone levels is exacerbated by the suppression of the hypothalamic-pituitary-gonadal axis by hyperestrogenemia. The high expression of aromatase enzyme in the adipose tissue enhances the conversion of androgens into estrogens which in turn exert a negative feedback on the hypothalamus and pituitary, leading to the inhibition of production of gonadotropin-releasing hormone (GnRH), luteinizing hormone (LH) and follicle stimulating hormone (FSH), and as a consequence, of testosterone by the testis resulting in hypogonadotropic hypogonadism (HH). Though bone loss is a well recognized side effect of AI in certain populations, such as women with breast cancer, HH obese men present high levels of circulating estrogens that could potentially prevent them from bone loss, estradiol being the main regulator of the male skeleton. This study is designed to determine if aromatase inhibitors in combination with weight loss, compared to weight loss alone, will have a positive effect on muscle strength, symptoms of hypogonadism, and body composition without negatively impacting bone mineral density and bone quality. Results from this study will help determine if certain groups of obese patients would benefit from therapy with aromatase inhibitors.
The goal of this study is to learn more about how kisspeptin, a naturally occurring hormone, affects women with high levels of prolactin (also called hyperprolactinemia). All participants will receive kisspeptin in a pulsatile fashion. Subjects in one group will attend two 12-hour visits with frequent blood draws. Subjects in the second group will wear a pump that administers kisspeptin subcutaneously (SC) over eight days and attend seven short blood sampling visits.
Multicenter study consisting of two study periods as follows: a 90-day Treatment Period, with potential extension by 30 days for those patients requiring a dose increase, as determined by the treating physician. Participants receiving 122.5mg of NATESTO (5.5 mg of testosterone) per nostril twice daily may have an increased daily dose adjustment on Day 90, based on their hypogonadism symptoms.
A Phase 2, open-label, randomized, cross-over, pharmacokinetic study designed to determine the effect of meals of various amounts of fat given immediately prior to dosing on the pharmacokinetics of oral testosterone undecanoate. Approximately 20 hypogonadal subjects will be dosed for a 14 day run-in period. This will be followed by a randomized sequence of five periods over a 6 day confinement period. Subjects will receive a randomly ordered sequence of breakfast meals containing various amounts of fat, fasting, 15 g, 30 g, 45 g and a high fat breakfast consistent Guidance for Industry on Food-Effect Bioavailability and Fed Bioequivalence Studies.
Phase IIb, multicentre, double-blind, randomised, placebo-controlled parallel-group 36-week study evaluating safety and efficacy of BGS649 in male obese subjects with hypogonadotropic hypogonadism (HH)
Sexual steroids administered to supra-physiological doses are likely to change the carbohydrate and lipid metabolism. Investigators propose to study in 12 hypogonadal men hypogonadotropic or hypergonadotropic treated with aromatase inhibitor, the respective effects of estradiol, testosterone or both steroids administered in a cross-over Latin squares plan on insulin sensitivity measured by the reference method of the hyperinsulinemic euglycemic clamp.
Evaluation of the safety and tolerability of testosterone enanthate (TE) following a single dose via QuickShot® Testosterone (QST) when administered by intended users in a usability study.
The study evaluates the effect of Fenugreek seed extract (Furosap) in management of symptomatic hypogonadism as fenugreek seed extract is a testosterone booster. Fenugreek seeds extract are known to possess protodioscin and the extract is reported to improve sperm count, sperm morphology and protective effect on male reproductive system. All the participants will receive one capsule (500 mg) of furosap once a day.
The purpose of this study is to evaluate the safety and efficacy of BGS649 in male obese subjects with hypogonadotropic hypogonadism. All subjects will be treated for a maximum of 24 weeks. Some subjects who complete 24 weeks of treatment will be invited to participate in a 6-month blinded safety extension study (Protocol MBGS206). The study is planned to enroll 268 subjects.
