Efficacy and Safety of Triptorelin 3-Month Formulation in Chinese Children with Central Precocious Puberty: A Phase 3, Open-Label, Single-Arm Study. Adv Ther 2023; 40:4574-4588. [PMID: 37584898 PMCID: PMC10499740 DOI: 10.1007/s12325-023-02617-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Accepted: 07/14/2023] [Indexed: 08/17/2023]
Abstract
INTRODUCTION Triptorelin is available as 1- and 3-month prolonged-release (PR) formulations; at the time of the study, only the former was approved for central precocious puberty (CPP) in China. This study assessed the efficacy and safety of the triptorelin 3-month PR formulation in Chinese children with CPP. METHODS In this 12-month, prospective, open-label, multicentre, single-arm study (NCT04736602), Chinese children (mean age [standard deviation (SD)], 7.6 ± 0.8 years) with CPP received triptorelin pamoate 15 mg on day 1 and at months 3, 6 and 9. The primary endpoint was the proportion with luteinizing hormone (LH) suppression (stimulated peak LH ≤ 3 IU/L after gonadotropin-releasing hormone [GnRH] stimulation) at month 3. Secondary endpoints included changes from baseline in hormone levels and clinical parameters, as well as safety assessments. RESULTS Overall, 32 children were enrolled, including three boys. LH suppression to prepubertal levels (≤ 3 IU/L) after GnRH stimulation was observed in 100%, 93.5% and 93.5% of participants at months 3, 6 and 12, respectively. Basal and peak LH and follicle-stimulating hormone levels were substantially suppressed at months 3, 6 and 12, and most participants showed sex hormone suppression. At months 6 and 12 respectively 92.9% and 89.3% of girls had stable breast development, and all boys had stable genital development. There was a decrease in mean growth velocity from baseline (8.96 cm/year) to months 3, 6 and 12 (8.07, 5.24 and 6.94 cm/year, respectively). The mean difference between bone and chronological age decreased from baseline (2.85 years) to month 12 (2.39 years). In girls, uterine length was stable or reduced at month 12; in boys, testicular volume was reduced. Triptorelin was well tolerated. CONCLUSION The triptorelin 3-month PR formulation demonstrated similar efficacy to that previously reported in non-Chinese patients with CPP and had an acceptable safety profile. This supports triptorelin 3-month PR as a viable option for Chinese children with CPP.

Efficacy of Leuprorelin 3-Month Depot (11.25 mg) Compared to 1-Month Depot (3.75 mg) for Central Precocious Puberty in Chinese Girls: A Prospective Cohort Study. Int J Endocrinol 2022; 2022:1043293. [PMID: 36590006 PMCID: PMC9800096 DOI: 10.1155/2022/1043293] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Revised: 11/08/2022] [Accepted: 12/07/2022] [Indexed: 12/24/2022] Open
Abstract
OBJECTIVE A 3-month depot of leuprorelin acetate (LA) was introduced in China in July 2020. However, the clinical experience is limited. The purpose of this study was to compare the efficacy of a LA 11.25 mg 3-month depot with that of a 3.75 mg 1-month depot in suppressing pubertal development for the treatment of central precocious puberty (CPP). Subjects and Methods. A prospective study, including 78 girls with CPP treated with LA, was conducted. 31 patients were treated with a LA 3-month depot, and 47 were treated with a LA 1-month depot. Participants were interviewed at baseline and 6 months. Anthropometric, metabolic, and reproductive data were assessed at each interview. Bone age, serum endocrine hormones, maximum diameter of uterus and volume of ovary of each patient were evaluated. A pharmacoeconomic evaluation was also conducted. RESULTS Treatment with a 3-month depot was similar to treatment with a 1-month depot in terms of baseline characteristics. After 6 months of treatment, a suppressed level of luteinizing hormone (LH) (LH < 2.5 IU/L) was found in 100% and 95% of the 11.25 mg and 3.75 mg groups, respectively. LH decreased from 2.11 ± 1.83 and 2.82 ± 2.31 at baseline (P=0.172) to 0.37 ± 0.39 and 0.44 ± 0.76 (P=0.758) in the 3-month and 1-month groups, respectively. Follicle stimulating hormone and estradiol levels, bone age/chronological age (BA/CA), height velocity, maximum diameter of uterus and volume of ovary did not show any distinction between the two groups after 6 months of treatment, but both were significantly ameliorated compared with the baseline. The loss of working time of parents and study time of patients and the numbers of visits, injections and laboratory examinations obviously decreased in the 3-month depots. CONCLUSION An LA 3-month depot was equally effective and safe as a 1-month depot for hormonal suppression and bone maturation inhibition, providing clinical experience in China. The 11.25 mg depot of LA is a safe, efficient, and economical treatment method for the advanced activation of the hypothalamic-pituitary-gonadal (HPG) axis.

Chung LY, Kang E, Nam HK, Rhie YJ, Lee KH. Efficacy of Triptorelin 3-Month Depot Compared to 1-Month Depot for the Treatment of Korean Girls with Central Precocious Puberty in Single Tertiary Center. J Korean Med Sci 2021; 36:e219. [PMID: 34463062 PMCID: PMC8405405 DOI: 10.3346/jkms.2021.36.e219] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/11/2021] [Accepted: 07/21/2021] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND Triptorelin depot is largely used to treat central precocious puberty (CPP) in children, and a 3-month depot has been introduced. However, data about the 3-month gonadotropin-releasing hormone use for treatment of CPP in Korean girls are not available. This study was conducted to compare the efficacy of a triptorelin 11.25 mg 3-month depot with that of a 3.75 mg 1-month depot in suppressing pubertal development for the treatment of CPP. METHODS A retrospective study, including 106 girls with CPP treated with triptorelin, was conducted. Fifty patients were treated with a triptorelin 3-month depot, and 56 were treated with a triptorelin 1-month depot. Serum luteinizing hormone (LH), follicle-stimulating hormone, and estradiol levels were analysed every 6 months after the visit. The height and bone age of each patient was evaluated at the beginning of treatment, after 6 months, and one year after therapy. RESULTS The baseline characteristics of the girls treated with a 3-month depot were similar to those of the girls treated with a 1-month depot. A suppressed levels of LH to the triptorelin injection (serum LH < 2.5 IU/L) at 6 months was seen in 90.0% and 98.2% of the girls treated with the 3-month and 1-month depots, respectively (P = 0.160). After 1 year of treatment, a suppressed levels of LH was seen in 93.5% and 100% of the girls treated with the 3-month and 1-month depots, respectively (P = 0.226). Height velocity showed no significant difference between the two groups. Degree of bone age advancement decreased from 1.22 ± 0.07 and 1.22 ± 0.08 years at baseline (P = 0.914) to 1.16 ± 0.07 and 1.17 ± 0.08 in the girls treated with the 3-month and 1-month depots after 1 year, respectively (P = 0.481). CONCLUSION This study showed that the efficacy of long-acting triptorelin 3-month was comparable to 1-month depot regarding hormonal suppression and inhibition of bone maturation. The triptorelin 11.25 mg 3-month depot is an effective treatment for girls with CPP.

Abstract
OBJECTIVES Treatment of central precocious puberty (CPP) is based on administration of GnRH agonists in order to suppress hypothalamic-pituitary-gonadal axis and thus induce the stabilization or regression of pubertal development. Our aim was to determine whether the single basal serum LH and/or FSH concentration could be an effective tool to assess the efficacy of treatment to suppress activation of hypothalamic-pituitary axis. PATIENTS AND METHODS Serum LH and FSH were measured before and after the GnRH injection, as well as E2 basal levels in 60 girls with documented idiopathic CPP at diagnosis and 18 and 30 months after the beginning of therapy. RESULTS At diagnosis, peaks of >5 IU/L of LH and of FSH were observed in 100 and 91.6% of girls, respectively, with basal LH values of <1 IU/L in 70% and basal FSH levels of <1 IU/L in 10%. E2 were <20 pg/mL in 36.6%. After 18 months, a suppressed peak (i.e. <3 IU/L) was recorded in 85% of girls (p<0.01) for LH and in 98.3% for FSH (p<0.01). Basal LH <1 IU/L was detected in 85% (p<0.01) and basal FSH ≤1 IU/L in 40% (p<0.01). Serum E2 ≤20 pg/mL was recorded in 61.6% (p<0.01). After 30 months, all patients showed LH suppressed peak (p<0.01) and 98.3% suppressed FSH peak (p<0.01). 100% showed basal LH concentrations <1 IU/L (p<0.01) and 38.3% FSH basal values <1 UI/mL (p<0.01). E2 ≤20 pg/mL was observed in 32.72% (p=NS). CONCLUSIONS Basal LH values are a reliable indicator of the efficacy of GnRHa therapy after 30 months of GnRHa therapy.

Abstract
CONTEXT Gonadotropin-releasing hormone agonists (GnRHas) are standard of care for central precocious puberty (CPP). A 6-month subcutaneous injection has recently been approved by the Food and Drug Administration. OBJECTIVE Determine efficacy, pharmacokinetics, and safety of 6-month 45-mg subcutaneous leuprolide acetate for CPP. DESIGN Phase 3 multicenter, open-label, single-arm study. SETTING 25 sites in 6 countries. SUBJECTS 64 GnRHa-naïve children with CPP (age: 7.5 ± 0.1 years) received study drug: 59 completed the study. INTERVENTION(S) 2 doses of 45-mg subcutaneous leuprolide acetate (0.375 mL) at 0 and 24 weeks; children were followed for 48 weeks. MAIN OUTCOME MEASURE(S) Percentage of children with serum luteinizing hormone (LH) <4 IU/L 30 minutes following GnRHa stimulation at week 24. RESULTS 54/62 (87%) children achieved poststimulation LH <4 IU/L at week 24; 49/56 (88%) girls and 1/2 boys maintained peak LH <4 IU/L at week 48. Mean growth velocity decreased from 8.9 cm/year at week 4 to 6.0 cm/year at week 48. Mean bone age was advanced 3.0 years beyond chronological age at screening and 2.7 years at week 48. Breast pubertal stage regressed or was stable in 97% of girls and external genitalia development regressed in both boys. Adverse events were mild and did not cause treatment discontinuation. CONCLUSIONS A small volume of 45-mg subcutaneous leuprolide acetate administered at a 6-month interval effectively suppressed pubertal hormones and stopped or caused regression of pubertal progression. This long-acting GnRHa preparation of leuprolide acetate is a new, effective, and well-tolerated therapy for children with CPP.

Abstract
The aim of this study is to compare the clinical and biochemical outcomes of triptorelin acetate (TPA) versus triptorelin pamoate (TPP) treatment in girls with central precocious puberty. A total of 60 patients with idiopathic CPP were retrospectively recruited. Thirty girls were treated with triptorelin acetate 3.75 mg/month (TPA group) and thirty girls in a second group received triptorelin pamoate 3.75 mg/4 weeks (TPP group). Patient follow-up at 12 and 24 months included GnRH Test at 12 months and baseline LH at 24 months. Patients were monitored with pelvic ultrasound, X-Ray of the hand and wrist and anthropometric evaluations. A total of 60/60 girls showed a good response to both formulations. Significant reductions in basal and LH peaks, estradiol values, breast pubertal stage, progression of bone age and growth velocity rate after 12 months treatment were obtained in both groups, demonstrating the equivalence of the two formulations in regulating the hypothalamic-pituitary-gonadal (HPG) axis. Triptorelin pamoate provided a more effective and significant reduction in LH peak after 12 months in comparison with triptorelin acetate more effective in reducing ovarian volume and endometrial thickness. Both formulations were equivalent, even though the LH peak was significantly lower in girls treated with triptorelin pamoate.

Abstract
INTRODUCTION Triptorelin depot is largely used to treat central precocious puberty (CPP) in children. Areas covered: This review updates triptorelin depot treatment of CPP, focusing on trials that compared 3.75 mg/28 day treated and untreated children till the adult height (AH). Efficacy of the new 11.25 mg/90 days or 22.5 mg/6 month formulations in suppressing pituitary-gonadal axis in short-term trials is also addressed. Short- and long-term safety was summarized. Expert commentary: Long experience on triptorelin depot use in children with CPP is available. Outcome differences on AH are reported; they may be due to heterogenicity of treated patients; some items remain to be optimized. No long term-adverse events on reproductive function are reported; additional studies would clarify if CPP per sè or triptorelin depot administration may increase hyperandrogenism and/or polycystic ovary syndrome risk in adulthood. The quarterly formulation seems to be able to suppress pituitary-gonadal axis and pubertal development and to determine similar end-results as monthly formulation, but additional trials are needed. Few data are available for the 22.5 mg/6 month formulation. Triptorelin depot treatment of CPP should be restricted to tertiary pediatric endocrinology centers, considering that some uncertainties still exist and that rare but serious adverse events may occur.

Abstract
BACKGROUND/AIMS A meta-analysis was undertaken to assess the effect of triptorelin 11.25 mg 3-month prolonged-release formulation in central precocious puberty (CPP). METHODS All available clinical studies with triptorelin 11.25 mg were included. The primary outcome was the proportion of children with suppressed luteinising hormone (LH) response (peak LH ≤3 IU/L) to the gonadotrophin-releasing hormone (GnRH) test 3 months after triptorelin 11.25 mg injection. Secondary outcomes included: the proportion with suppressed peak LH response at 6 months and the proportion with suppressed peak follicle-stimulating hormone (FSH) response (≤3 IU/L), suppressed oestradiol (≤20 pmol/L) in girls or suppressed testosterone (≤30 ng/dL) in boys at 3 months. RESULTS 153 children (13 boys, 140 girls) were included. The proportion with a suppressed peak LH response to the GnRH test was 87.6% (95% CI: 81.3-92.4, p < 0.0001, for a proportion >70%) and 92.8% (95% CI: 87.5-96.4, p < 0.0001, for a proportion >70%) at 3 and 6 months, respectively. FSH peak, oestradiol, and testosterone were suppressed in 86.7% (95% CI: 79.1-92.4), 97.1% (95% CI: 91.6-99.4), and 72.7% (95% CI: 39.0-94.0) of children at 3 months, respectively. CONCLUSION Triptorelin 11.25 mg 3-month formulation is efficacious in suppressing LH peak and other gonadal hormones and in slowing the progression of CPP in children.
