Objectives: The overall clinical question is whether LH supplementation to men in indication for FSH according to the AIFA note 74, or with HH, will improve spermatogenesis and pregnancy rate (spontaneous or after ART) over FSH alone or FSH+hCG. However, since LH has never been used in men so far, the first, specific object of this study is the assessment of pharmacodynamics and safety profile of LH in HH men. To this end, this study will evaluate the pharmacodynamics and safety profile of recombinant LH (Luveris) and compare the response to Luveris and urinary hCG (Gonasi HP) in HH men. The pharmacodynamics will be assessed primarily for testosterone levels in response to increasing doses of LH and the comparison of the response to a fix dose of hCG, and later for more extend steroid profile. Methods: Multicentre longitudinal, interventional, randomized, open-label, phase II, clinical trial, assessing pharmacodynamics of LH in acquired HH men. The statistical hypothesis is non-inferiority of the highest LH dose employed compared to a fix hCG dose. Primary endpoint: serum testosterone levels evaluated by liquid-chromatography, tandem mass spectrometry (LC-MS/MS). Secondary endpoints: Safety and tolerability as determined by AE reporting, vital signs, and ECG, stereognosis (inhibin B, free testosterone, sex hormone binding globulin (SHBG), estradiol, whole steroid profile provided by LC-MS/MS) and testicular volume. Patients: 32 men with acquired HH, including HH after neurosurgery for tumours or HH due to pituitary adenoma-related mass effect. Patients will be randomized (1:1) according to a permuted- blocks randomization list, to the study group, treated with Luveris (increasing doses at two weekly intervals), or to the control group treated with Gonasi HP (2000 IU twice/week). In the study group, increasing LH dosages will be administered to obtain a testosterone dose-response curve, starting with the minimum expected efficient dose (75 IU/d, sc) for two weeks followed by 150, 225 and 300 IU at two-weekly interval, respectively. The control group will be treated by the standard approach, i.e. hCG 2000 IU IM twice-weekly for 8 weeks. Patients will be further followed up for 4 weeks after treatment withdrawal. During the study, the patients will be evaluated two times per week during the treatment phase and every two weeks in the follow-up phase.
The purpose of this study is to compare the effects of 12 months of treatment with enclomiphene 12.5 mg, 25 mg, or placebo capsules on body composition and metabolic parameters in overweight men with acquired hypogonadotropic hypogonadism [confirmed morning testosterone (T) ≤300 ng/dL] following a 6 month diet and 15 month exercise program.
