Primary outcomes4
Outcomes the sponsor listed as primary.
Change From Baseline in Log-Transformed Testicular Volume (TV) to Week 64
Time frame · Baseline and Week 64
Registry description
Participants underwent testicular ultrasound of left and right testes at pre-specified time points to measure TV. TV was measured as the sum of volumes of left and right testes. The linear mixed model with a fixed effect for baseline and Week 64 and a random effect for participant was used to calculate the mean change in log-transformed TV and associated 95% confidence intervals (CIs) from baseline to Week 64. The geometric mean ratio and its 95% CIs for TV were obtained by exponentiation. The ratio \> 1 indicated an increase in TV from baseline.
Number of Participants Who Experienced an Adverse Event (AE)
Time frame · Up to approximately 71 Weeks
Registry description
An adverse event was defined as any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. The number of participants who experienced an AE was reported.
Number of Participants Who Discontinued Study Treatment Due to an AE
Time frame · Up to approximately 64 Weeks
Registry description
An adverse event was defined as any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment.

Change From Baseline in Testicular Echogenicity to Week 12, Week 36, and Week 64
Time frame · Baseline, Week 12, Week 36, and Week 64
Registry description
Testicular Echogenicity was determined by evaluating the sonographic patterns obtained on testicular ultrasound of right and left testes at baseline, Week 12, Week 36 and 64. The sonographic patterns were assessed by central imaging unit by an independent radiologist and categorized as Hypoechoic (decreased echogenicity as compared to echogenicity at baseline), Isoechoic (same echogenicity as compared to echogenicity at baseline) and Hyperechoic (increased echogenicity as compared to echogenicity at baseline). The number of participants with a sonographic pattern at Weeks 12, 36 and 64 were reported.
Change From Baseline in Luteinizing Hormone (LH) to Week 12, Week 36, and Week 64
Time frame · Baseline, Week 12, Week 36, and Week 64
Registry description
LH is a gonadotropin secreted from the anterior pituitary and is a marker for spontaneous puberty. Blood samples were collected at baseline, Week 12, Week 36 and Week 64 to report the mean change from baseline in LH level to Weeks 12, 36 and 64.
Change From Baseline in Calculated Free Testosterone (T) to Week 12, Week 36, and Week 64
Time frame · Baseline, Week 12, Week 36, and Week 64
Registry description
Blood samples were collected at baseline, Week 12, Week 36 and Week 64 to report the mean change from baseline in T level to Weeks 12, 36 and 64. The change from baseline in T level to Week 12, 36, and 64 could not be calculated as planned because only 2 participants had baseline T level values which were insufficient to provide the trend change from baseline in T level to Week 12, 36, and 64.
Change From Baseline in Total Testosterone (Total T) to Week 12, Week 36, and Week 64
Time frame · Baseline, Week 12, Week 36, and Week 64
Registry description
Total T is a marker for progress of puberty in males. Total T levels increase during puberty as the testes respond to the gonadotropins. Blood samples were collected at baseline, Week 12, Week 36 and Week 64 post dose to report the mean change from baseline in Total T level to Weeks 12, 36 and 64. A negative value indicated a lower Total T level.
Change From Baseline in Estradiol (E2) to Week 12, Week 36, and Week 64
Time frame · Baseline, Week 12, Week 36, and Week 64
Registry description
E2 levels rise during puberty in males when some of the T secreted is aromatized. Blood samples were collected at baseline, Week 12, Week 36 and Week 64 to report the mean change from baseline in E2 level to Weeks 12, 36 and 64. A positive value indicated a higher E2 level.
Change From Baseline in Sex Hormone-Binding Globulin (SHBG) to Week 12, Week 36, and Week 64
Time frame · Baseline, Week 12, Week 36, and Week 64
Registry description
SHBG is a blood protein that controls the amount of T body tissues in males. SHBG is regulated by the ratio of T and E2 levels in addition to other factors (thyroid hormone status, dietary factors, certain diseases and medications). Blood samples were collected at baseline, Week 12, Week 36 and Week 64 to report the mean change from baseline in SHBG level to Weeks 12, 36 and 64. A negative value indicated a lower SHBG level.
Change From Baseline in Anti-Müllerian Hormone (AMH) to Week 12, Week 36, and Week 64
Time frame · Baseline, Week 12, Week 36, and Week 64
Registry description
AMH is a marker for progress of puberty in males. Blood samples were collected at baseline, Week 12, Week 36 and Week 64 to report the mean change from baseline in AMH level to Weeks 12, 36 and 64. A negative value indicated a lower AMH level.
