| NCT01709331 | A Study of the Efficacy and Safety of Corifollitropin Alfa (MK-8962) in Combination With Human Chorionic Gonadotropin (hCG) in Adult Men With Hypogonadotropic Hypogonadism (HH) (P07937) | PHASE3 | COMPLETED | 18 | — | — | Feb 11, 2013 | Apr 8, 2015 | May 24, 2024 | - | — |
Participants underwent testicular ultrasound in the pretreatment phase at Weeks -16, -8, -1; and during the combined treatment phase at Baseline (predose, Day 1) and at Weeks 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, and 52. The testicular volume was measured as the sum of volumes of left and right testes. The mean change from Day 1 in log-transformed testicular volume was analyzed using a mixed model with a fixed effect for time point and a random effect for the participant. For each time point, the mean change from Day 1 to that time point and the associated 95% confidence interval (CI) was calculated. The geometric mean fold change in testicular volume and its 95% CI was obtained by exponentiation.
Blood samples were collected for assessment of anti-corifollitropin alfa antibodies in the pretreatment phase at Week -16 and Week -1; during the combined treatment phase at Weeks 4, 16, 28, 50, 52; and at the post-treatment follow-up visit, which could occur from Week 53 up to Week 57.

| Corifollitropin alfa 150 μg + hCG | EXPERIMENTAL | During a 16-week pretreatment phase, participants will receive twice-weekly subcutaneous (SC) injections of hCG 1500 or 3000 international units (IU). Eligible participants will then be enrolled in the combined treatment phase in which they will receive a single dose of corifollitropin alfa 150 μg by SC injection once every 2 weeks for 52 weeks. In addition, eligible participants will continue to receive twice-weekly hCG injections on the same schedule as the pretreatment phase. |
