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.

[PMID: 34313086 DOI: 10.1515/jpem-2021-0245] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2021] [Accepted: 06/20/2021] [Indexed: 12/23/2022]
Abstract
OBJECTIVES The aim of this study was to evaluate the resilience of girls with central precocious puberty (CPP) during treatment with a gonadotropin-releasing hormone agonist (GnRHa) and compare these results with their healthy peers. METHODS The Connor-Davidson Resilience Scale (CD-RISC) is a self-report scale used to quantify resilience, which is divided into seven subgroups (hardiness, coping, flexibility, purpose, optimism, regulation of emotion and cognition (REC), and self-efficacy). Fifty-one girls with CPP receiving GnRHa treatment and 51 healthy controls were involved in the study. Anthropometric measurements were evaluated and CD-RISC was performed at least six months after the initiation of GnRHa treatment. RESULTS There was no statistically significant difference between the anthropometric evaluations of girls with CPP and the control group. Similarly, the total score and subgroup scores of patients with CPP and the control group showed no statistically significant difference. In the correlation analysis, there was a weak negative correlation between height and flexibility (r=-0.314 p=0.025), height SDS and flexibility (r=-0.254 p=0.092), height SDS, and purpose (r=-0.285 p=0.058). Also, there was a weak negative correlation between REC and weight (r=-0.435 p=0.003), REC and weight SDS (r=-0.461 p=0.002), REC and height (r=-0.269 p=0.077), REC and height SDS (r=-0.322 p=0.033), REC and BMI (r=-0.289 p=0.058), and REC and BMI SDS (r=-0.353 p=0.019). CONCLUSIONS The resilience of girls with CPP treated with GnRHa was found to be similar to their healthy peers. The early diagnosis of the disease and adequate treatment may decrease the discrepancy of somatic changes between girls with CPP and their peers, which may help them to overcome the stress of CPP and long-term treatment.

Abstract
PURPOSE Gonadotropin-releasing hormone agonist (GnRHa) has been the mainstay of central precocious puberty (CPP) treatment for decades, but few reports have compared the efficacy of 1-month and 3-month depot GnRHa formulations. This study investigates the short-term efficacy of 1-month and 3-month GnRHa depots in girls with CPP. METHODS Overall, 150 girls with CPP were included in a retrospective review of medical records. Subjects in group 1 (n=105) were treated with 1-month GnRHa depots for ≥12 months, and those in group 2 (n=45) were treated with 1-month GnRHa depots for 6 months followed by 3-month GnRHa depots for ≥6 months. Anthropometric and biochemical data were compared between the groups at 3-time points (after 0, 6, and 12 months of GnRHa treatment). RESULTS Demographic and clinical characteristics did not differ between the groups at baseline or after 6 months of GnRHa treatment. After 12 months of GnRHa treatment, patients in the both groups showed no difference in bone age (BA), chronological age (CA), BA-CA difference, height standard deviation score (SDS) for CA and BA, or body mass index SDS for CA and BA. The sexual maturity rate of the breast was prepubertal at 12 months in most of subjects. GnRH-stimulated luteinizing hormone (LH) level was suppressed during GnRHa treatment in both groups at 6 and 12 months, although the LH level in group 2 was higher than that in group 1. CONCLUSION Treating CPP with a 3-month GnRHa depot showed short-term efficacy comparable to that with a 1-month depot in anthropometric parameters and pubertal suppression.

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
BACKGROUND The impact of gonadotropin-releasing-hormone-analogue (GnRHa) treatment on weight and body composition is controversial. Exploring the nutritional, psychological patterns of this population may aid to clarify this propensity to gain weight. This prospective observational study aimed to evaluate longitudinal changes in adiposity, nutrition and quality of life in girls with central precocious/early-fast puberty (CPP/EFP) during GnRHa treatment. METHODS Thirty-two GnRHa-treated girls with CPP/EFP and 27 prepubertal girls (7-10 years) were included in the analysis. Outcome measures assessed at baseline for CPP/EFP and the control groups and during up to two years of GnRHa treatment for the CPP/EFP group, included anthropometrics, body-composition, basal-metabolic-rate (BMR), 3-day food-diaries, child eating-behavior questionnaire, and pediatric quality-of-life questionnaire (PedsQL). RESULTS Girls with CPP/EFP had higher pretreatment BMI-SDS, fat percentages, waist circumference and waist-per-height (p<0.01 for all), and lower psychosocial functioning than controls (p<0.05). Changes in anthropometric and body composition measurements indicated a gradual increase in adiposity and a decrease in muscle mass (p<0.001 for all). Dynamics in body composition could not be explained by the participants' self-reported dietary patterns and physical activity levels or by the measured BMR, which revealed an adequate and relatively low energy intake as compared to energy requirements. A gradual decline in physical functioning (PedsQL) after one and two years of GnRHa treatment was observed (p<0.001). CONCLUSIONS Our findings highlight the need for comprehensive surveillance in girls with CPP/EFP. Dynamics in weight status and body composition during GnRHa treatment indicate the need for tailored nutritional and physical activity counseling aimed at preventing obesity.

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
Objective: To describe the timeline to diagnosis for children with central precocious puberty (CPP) and evaluate their psychosocial and health-related quality of life (HRQoL).Methods: A cross-sectional survey was used to prospectively collect data from caregivers, recruited via the MAGIC Foundation, of children with CPP. The control (non-CPP) group was recruited from a national panel of parents/caregivers. After completing a screening survey, respondents completed a burden of illness survey. Respondents in both groups completed the Pediatric Quality of Life Inventory (PedsQL) and Patient-Reported Outcomes Measurement Information System (PROMIS) peer relationship instruments.Results: Responses from 142 caregivers of children with and 300 without CPP were assessed. Mean time to treatment after a child's visit to the pediatric endocrinologist was 220 days and time from onset of symptoms to initiating treatment was approximately 2 years. Responses to HRQoL inventories were all lower in children with CPP versus non-CPP. Adjusted mean (± standard error) PedsQL total (65.3 ± 1.8 versus 75.7 ± 1.2), Psychosocial Health Summary (62.4 ± 1.8 versus 73.4 ± 1.2), and Physical Health Summary (70.7 ± 2.2 versus 79.9 ± 1.5) scores were significantly lower (p < .01) in CPP versus non-CPP group. PROMIS peer relationship T score (± standard error) was numerically lower for the CPP versus non-CPP group (45.4 ± 1.0 versus 47.4 ± 0.7, p = .11).Conclusions: In clinical practice, there is a longer than expected delay between CPP symptom onset and referral to an endocrinologist and ultimate treatment. Children with CPP experience a substantial disease burden with a significant impact on emotional, social, and physical functioning compared with children without CPP.

Abstract
Introduction: In recent years, the treatment of idiopathic central precocious puberty using gonadotropin-releasing hormone agonist (GnRH) agonist has been considered as a common treatment. To date, there is not much information about the effect of GnRH agonist treatment on pediatric thyroid function. Aim: The aim of this study was to evaluate the influence of GnRH treatment on thyroid function tests in children with central idiopathic precocious puberty. Material and Methods: This cross-sectional study investigated 50 children with idiopathic precocious puberty treated with GnRH agonist, who were referred to Bahrami pediatric hospital, Tehran, Iran. Patients` height, weight, and symptoms of hypothyroidism were evaluated every two months. Thyroid function tests, T4 and thyroid-stimulating hormone (TSH), were reviewed every 6 months. Data were analyzed using SPSS Statistics, Version 18. Results: The majority of the children who participate in this study were female. 72% of children with central idiopathic precocious puberty had a significant increase in TSH level (P=0.002). In this group of patients, 66% and 6% had subclinical and clinical increases in thyroid function tests, respectively. The estimated time to thyroid dysfunction was 12.37 months. It is found that only 2% of patients showed thyroid dysfunction during the first 6 months of the treatment. Conclusion: The results of this study showed that more than 70% of children who were undergoing GnRH agonist treatment for central precocious puberty had impaired thyroid function (especially subclinical hypothyroidism). Therefore, evaluating thyroid function in children with precocious puberty who are under treating with GnRH agonist, would be reasonable; especially one year after initiating the treatment.

Abstract
Objective This study was done to evaluate the emotional and behavioral status of precocious puberty patients and analyze the effect of gonadotropin-releasing hormone agonist (GnRHa) treatment. Methods Sixty-six female precocious puberty patients were enrolled prospectively for the study at Kangdong Sacred Heart Hospital of Hallym University Medical Center from September 2011 to December 2012 and self-administered questionnaire was completed during the GnRHa treatment initiation period and after 12 months from the first injection. The patients were evaluated using the Korean version of Child Behavior Checklist (K-CBCL) and Children's Depression Inventory (CDI). Results A total of 30.3% (n = 20) of the patients scored within the clinical range for one or more scales of K-CBCL at the initiation of GnRHa treatment, but only 10.6% (seven patients) were within the clinical range after 1 year of treatment. Average CDI scores of the patients decreased from baseline 6.5 ± 6.0 to 4.9 ± 4.7 after GnRHa therapy. Conclusions This study shows that both K-CBCL and CDI scores improved from baseline score ranges after 1 year of GnRHa treatment in female central precocious puberty patients while significant psychological problems of clinical range amongst them were not noted.

Abstract
OBJECTIVE There are no doubts about the clinical benefits of treatment with GnRH analogs for patients diagnosed with central precocious puberty (CPP). However, laboratory monitoring of CPP is still a matter of considerable controversy in the literature. Therefore, the main objective of this study was to evaluate the cut-off values of stimulated LH that determine gonadotrophic suppression. METHODS Twenty-four girls, on treatment with leuprorelin acetate (LA) at 3.75 mg IM every 28 days, were studied. The clinical parameters used to indicate clinical effectiveness were regression or maintenance of sexual characteristics according to the Tanner stage, growth velocity reduction, reduction or maintenance of the difference between bone age and chronological age and maintenance or improvement of the final height prediction. For the laboratory effectiveness test, basal estradiol, LH, and FSH levels were collected before and 1 and 2 h after the administration of 3.75 mg LA. RESULTS Eleven girls showed improvement in all clinical parameters, and their effectiveness tests were compared to those of the other patients to calculate the cut-off values, which were ≤3.64 IU/L (p=0.004*) for LH after 1 h and ≤6.10 IU/L (p<0.001*) for LH after 2 h. CONCLUSION The LH response after the LA stimulation test, associated with clinical data and within a context of CPP, constitutes a reliable and feasible resource and can assist in monitoring the effectiveness of treatment.

Abstract
The objective of this study was to assess the current use of patient-centered psychosocial assessments for the evaluation of children with central precocious puberty (CPP). Studies evaluating the psychosocial impact of CPP were identified through searches of the PubMed and Cochrane Library databases, ClinicalTrials.gov, a drug prescribing information database, and regulatory websites. Studies were screened using prespecified inclusion and exclusion criteria. Potentially relevant patient-centered outcome assessments (including patient-, parent- or observer-reported measures) used in the identified studies were evaluated in detail for their relevance in CPP. Of the 467 studies identified, 15 met the inclusion criteria. Frequently assessed concepts included depression and anxiety, behavior and behavioral problems, body image and self-esteem and personality type/characteristics. Among the assessments used in the identified studies, the Child Behavior Checklist, Pediatric Quality of Life Inventory (PedsQL), SF-10 for Children and Child Health Questionnaire were comprehensively evaluated. The PedsQL showed promise as a patient-centered outcome measure in CPP. Although there is a lack of validated tools measuring psychosocial health and health-related quality of life in patients with CPP, the PedsQL captures issues seen in this patient population and is relatively easy to administer. Further studies using this and other tools in children with CPP are needed.

Abstract
A 3-month depot formulation of leuprolide acetate (Luphere 3M Depot) with a mean microsphere diameter of 22.3 μm was prepared aseptically by spray-drying glacial acetic acid solution of the drug and polylactic acid, and lyophilization in a d-mannitol solution. The encapsulation efficiency and loading content of the drug in the Luphere 3M Depot were 94.7% and 9.92% (w/w), respectively. The in vitro release of leuprolide from the depot was substantially delayed and the release profile was similar to that of Lucrin Depot (Abbott Korea, Korea). The safety and pharmacokinetics of leuprolide were investigated over a period of 42 days in 20 prostate cancer patients following a subcutaneous injection of Luphere 3M or Lucrin Depot suspensions (leuprolide acetate dose of 11.25 mg) in a multi-center, randomized, single dose, parallel study. Both formulations were well tolerated by the patients and no serious adverse effects were observed during and after the study. No significant differences were observed in the maximum serum concentration (Cmax) and area under the curve (AUClast) of leuprolide between the two formulations. The results suggest comparable safety and efficacy profiles of Luphere 3M Depot and Lucrin Depot in clinical situations.

Abstract
Background: In central precocious puberty (CPP), the pulse secretion and release of gonadotropin-releasing hormone (GnRH) are increased due to early activation of the hypothalamic-pituitary-gonadal axis, resulting in developmental abnormalities with gonadal development and appearance of secondary sexual characteristics. The CPP without organic disease is known as idiopathic CPP (ICPP). The objective of the study was to evaluate the clinical efficacy and safety of domestic leuprorelin (GnRH analog) in girls with ICPP. Methods: A total of 236 girls with ICPP diagnosed from April 2012 to January 2014 were selected and were randomized into two groups. One hundred fifty-seven girls in the test group were treated with domestic leuprorelin acetate, 79 girls in the control group were treated with imported leuprorelin acetate. They all were treated and observed for 6 months. After 6-month treatment, the percentage of children with peak luteinizing hormone (LH) ≤3.3 U/L, the percentage of children with peak LH/peak follicle stimulating hormone (FSH) ratio <0.6, the improvements of secondary sexual characteristics, gonadal development and sex hormone levels, the change of growth rate of bone age (BA) and growth velocity, and drug adverse effects between two groups were compared. Results: After the treatment, the percentage of children with a suppressed LH response to GnRH, defined as a peak LH ≤3.3 U/L, at 6 months in test and control groups were 96.80% and 96.20%, respectively, and the percentage of children with peak LH/FSH ratio ≤0.6 at 6 months in test and control groups were 93.60% and 93.70%, respectively. The sizes of breast, uterus and ovary of children and the levels of estradiol (E2) were significantly reduced, and the growth rate of BA was also reduced. All the differences between pre- and post-treatment in each group were statistically significant (P < 0. 05), but the differences of the parameters between two groups were not significant (P > 0.05). Conclusions: Domestic leuprorelin is effective and safe in the treatment of Chinese girls with ICPP. Its effectiveness and safety are comparable with imported leuprorelin.

Abstract
OBJECTIVE To report our experience of treating central precocious puberty (CPP) with a GnRH analogue with respect to the final heights (FH) attained in patients who completed treatment. SUBJECTS AND METHODS Among 105 records of children diagnosed with precocious puberty, 62 cases (54 girls and 8 boys), who were treated with leuprolide acetate/3.75 mg/monthly, were selected, and divided into 4 groups: group 1 (G1), 25 girls who attained FH; group 2 (G2), 18 girls who completed treatment but did not reach FH; group 3 (G3), 11 girls still under treatment; and group 4 (G4), 8 boys, 5 of which attained FH. Treatment was concluded at a bone age of 12 years, and follow-up continued until FH was achieved. RESULTS In both G1 and G2 groups, height standard deviation score (SDS), weight-SDS and percentile of body mass index (PBMI) did not show intra/intergroup differences at the beginning and at interruption of treatment, but when added, G1+G2, height-SDS and weight-SDS differed significantly (p = 0.002 and 0.0001, respectively). In G1, 19 of 25 cases attained TH, and average height gain was 16.7 cm (7.7- 27.1); there was significant difference between FH and prediction of FH at the start (PFH at start) (p = 0.0001), as well as between PFH at interruption vs TH and vs FH (p = 0.007) with FH higher than TH (p = 0.004). Significant correlation was identified between FH and height gain after treatment. CONCLUSION As shown by some studies, GnRH analogue treatment was effective in children with CPP reaching FH near the genetic target.
