See 17 for PATIENT COUNSELING INFORMATION and Medication Guide.
LUPRON DEPOT-PED is indicated for the treatment of pediatric patients with central precocious puberty (CPP).
● LUPRON DEPOT-PED must be administered by a healthcare professional.
● Individualize the dose of LUPRON DEPOT-PED for each patient.
● Each LUPRON DEPOT-PED strength and formulation has different release characteristics. Do not use partial syringes or a combination of syringes to achieve a particular dose.
● In the case of inadequate suppression of pituitary gonadotropins and peripheral sex steroids with a maximal dosage, consider other available gonadotropin releasing hormone (GnRH) agonists indicated for the treatment of central precocious puberty.
● Discontinue LUPRON DEPOT-PED at the appropriate age of onset of puberty.
● Administer LUPRON DEPOT-PED 7.5 mg, 11.25 mg, or 15 mg for 1-month administration as a single-dose intramuscular injection once every month. ● The starting dose is based on the patient's weight (see Table 1).
● The dosage may need to be adjusted with changes in body weight.
● If adequate hormonal and clinical suppression is not achieved with the starting dose, increase the dosage to the next available higher dose (e.g., 11.25 mg or 15 mg at the next monthly injection).
● Monitor response with a GnRH stimulation test, basal luteinizing hormone (LH) or serum concentration of sex steroid levels beginning 1 to 2 months following initiation of therapy, with changing doses, or further as judged clinically appropriate in order to confirm maintenance of efficacy.
● Assess height (for calculation of growth rate) and bone age every 6 to 12 months.
● Use LUPRON DEPOT-PED 11.25 mg or 30 mg for 3-month administration once every three months (12 weeks) as a single-dose intramuscular injection.
● Monitor response with a GnRH stimulation test, basal LH or serum concentration of sex steroid levels at months 2 to 3, month 6 and further as judged clinically appropriate, to confirm maintenance of efficacy.
● Administer LUPRON DEPOT-PED as a single-dose intramuscular injection into the gluteal area, anterior thigh, or shoulder.
● Rotate injection sites within the same region from one injection to the next.
● Inject immediately after reconstitution. Discard if not used within 2 hours.
1. Visually inspect the LUPRON DEPOT-PED powder and diluent. Do not use the syringe if clumping or caking is evident. A thin layer of powder on the wall of the syringe is considered normal prior to mixing with the diluent. The diluent should appear clear and free from particulate matter. Do not use the diluent if it is not clear or there is particulate matter.
2. To prepare for injection, screw the white plunger into the end stopper until the stopper begins to turn. (see Figure 1 and Figure 2)
LuproLoc Safety Device should be activated after product injection, refer to Step 9 (Figure 7).
3. Hold the syringe upright. Release the diluent by slowly pushing the plunger for 6 to 8 seconds until the first stopper is at the blue line in the middle of the barrel. (Figure 3)
4. Keep the syringe upright. Mix the powder thoroughly by gently shaking the syringe until the powder forms a uniform suspension. The suspension will appear milky. If the powder adheres to the stopper or caking/clumping is present, tap the syringe with your finger to disperse. Do not use if any of the powder has not gone into suspension. (Figure 4)
5. Hold the syringe upright. With the opposite hand pull the needle cap upward without twisting.
6. Keep the syringe upright. Advance the plunger to expel the air from the syringe.Now the syringe is ready for injection.
7. After cleaning the injection site with an alcohol swab, administer the intramuscular injection by inserting the needle at a 90 degree angle into the deltoid, gluteal area, or anterior thigh. (Figure 5)
NOTE: Aspirated blood would be visible just below the luer lock connection if a blood vessel is accidentally penetrated. If present, blood can be seen through the transparent LuproLoc® safety device. If blood is present remove the needle immediately. Do not inject the medication. (Figure 6)
8. Inject the entire contents of the syringe intramuscularly immediately after reconstitution. The suspension settles very quickly following reconstitution.
9. Withdraw the needle. Once the syringe has been withdrawn, activate immediately the LuproLoc® safety device by pushing the arrow on the lock upward towards the needle tip with the thumb or finger, as illustrated, until the needle cover of the safety device is fully extended over the needle and a click is heard or felt. (Figure 7)
For depot suspension: a white lyophilized powder supplied in a single-dose, prefilled dual-chamber syringe with a colorless diluent is available as:
● Hypersensitivity to GnRH, GnRH agonists or any of the excipients in LUPRON DEPOT-PED. Anaphylactic reactions to synthetic GnRH or GnRH agonists have been reported [see Adverse Reactions (6.2)].
● Pregnancy: LUPRON DEPOT-PED may cause fetal harm [see Use in Specific Populations (8.1)].
During the early phase of therapy or after subsequent doses, gonadotropins and sex steroids may rise above baseline because of a transient stimulatory effect of the drug [see Clinical Pharmacology (12.2)]. Therefore, an increase in clinical signs and symptoms of puberty, including vaginal bleeding, may be observed during the first weeks of therapy or after subsequent doses [see Adverse Reactions (6)].
Psychiatric events have been reported in patients taking GnRH agonists, including LUPRON DEPOT-PED. Postmarking reports with this class of drugs include symptoms of emotional lability, such as crying, irritability, impatience, anger and aggression. Monitor for development or worsening of psychiatric symptoms during treatment with LUPRON DEPOT-PED [see Adverse Reactions (6.2)].
Postmarketing reports of convulsions have been observed in patients receiving GnRH agonists, including LUPRON DEPOT-PED. These included patients with a history of seizures, epilepsy, cerebrovascular disorders, central nervous system anomalies or tumors, and patients on concomitant medications that have been associated with convulsions such as bupropion and SSRIs. Convulsions have also been reported in patients in the absence of any of the conditions mentioned above [see Adverse Reactions (6.2)].
The following serious adverse reactions are described here and elsewhere in the label:
Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice.
LUPRON DEPOT-PED for 1-month administration
LUPRON DEPOT-PED 1-month administration was evaluated in a pivotal, open label, multicenter study in which 55 (49 female and 6 male) pediatric patients with central precocious puberty were enrolled. The age ranged from 1 to 8 years of age at the beginning of treatment; the mean age for females was 6.8 years (range: 1 to 9 years) and the mean age for males was 7.5 years (range: 4 to 9 years); 61.8% were Caucasian; 20% Black; 1.8% Oriental; and 16.4% Hispanic.
Adverse reactions that occurred in >2% of patients are shown in Table 2.

LUPRON DEPOT-PED for 3-month administration
LUPRON DEPOT-PED for 3-month administration was evaluated in a pivotal, open-label, multicenter, clinical study with 84 randomized pediatric patients with central precocious puberty; 76 (90.5%) were females and 8 (9.5%) were males. The age ranged from 1 to 11 years age at the beginning of treatment; 80/84 (95.2%) were 5 years or older, and female patients were younger than male; the mean age for 11.25 mg and 30 mg groups for females was 7.6 and 7.7 years, and for males 9.3 and 9.4 years, respectively; 58.3% were Caucasian; 22.6% were Black; 7.1% were Asian; 1.2% were Native Hawaiian or Other Pacific Islander; and 10.7% were Multi-race.
Adverse reactions that occurred in >2% of patients are shown in Table 3.
The following adverse reactions were reported in one patient and are listed below by system organ class:
Gastrointestinal Disorders – abdominal pain, nausea;
General Disorders and Administration Site Conditions – asthenia, gait disturbance, injection site abscess sterile, injection site hematoma, injection site induration, injection site warmth, irritability;
Metabolic and Nutritional Disorders – decreased appetite, obesity;

Psychiatric Disorders – crying, tearfulness;
Respiratory, Thoracic and Mediastinal Disorders – cough;
Skin and Subcutaneous Tissue Disorders – hyperhidrosis;
Vascular Disorders – pallor.
The following adverse events have been observed with post-approval use of leuprolide acetate in pediatric patients. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Allergic reactions: anaphylactic, rash, urticaria, and photosensitivity reactions.
General: chest pain, weight increase, decreased appetite, fatigue.
Laboratory Abnormalities: decreased WBC.
Metabolic: diabetes mellitus.
Musculoskeletal and Connective Tissue: tenosynovitis-like symptoms, severe muscle pain, arthralgia, epiphysiolysis, muscle spasms, myalgia.
Published literature and postmarketing reports indicate that bone mineral density may decrease during GnRH therapy in pediatric patients with central precocious puberty. Published studies indicate that after discontinuation of therapy, subsequent bone mass accrual is preserved and peak bone mass in late adolescence does not seem to be affected.
Neurologic: neuropathy peripheral, convulsion, insomnia.
Psychiatric Disorders: Emotional lability, such as crying, irritability, impatience, anger, and aggression has been observed with GnRH agonists, including LUPRON DEPOT-PED; Depression, including rare reports of suicidal ideation and attempt, has been reported for GnRH agonists, including LUPRON DEPOT-PED, in children treated for central precocious puberty. Many, but not all, of these patients had a history of psychiatric illness or other comorbidities with an increased risk of depression.
Reproductive System: vaginal bleeding, breast enlargement.
Skin and Subcutaneous Tissue: injection site reactions including induration and abscess, flushing, hyperhidrosis.
Vascular Disorders: hypertension, hypotension.
No pharmacokinetic-based drug-drug interaction studies have been conducted with LUPRON DEPOT-PED [see Clinical Pharmacology (12.3)] .
Administration of LUPRON DEPOT-PED in therapeutic doses results in suppression of the pituitary-gonadal system. Therefore, diagnostic tests of pituitary gonadotropic and gonadal functions conducted during treatment and up to six months after discontinuation of LUPRON DEPOT-PED may be affected. Normal pituitary-gonadal function is usually restored within six months after treatment with LUPRON DEPOT-PED is discontinued.
LUPRON DEPOT-PED is contraindicated in pregnancy [see Contraindications (4)].
LUPRON DEPOT-PED may cause fetal harm, when administered to a pregnant woman, based on findings from animal studies and the drug’s mechanism of action [see Clinical Pharmacology (12.1)]. The available data from published clinical studies and case reports and from the pharmacovigilance database on exposure to LUPRON DEPOT-PED during pregnancy are insufficient to assess the risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Based on animal reproduction studies, LUPRON DEPOT-PED may be associated with an increased risk of pregnancy complications, including early pregnancy loss and fetal harm. In animal reproduction studies, subcutaneous administration of leuprolide acetate to rabbits during the period of organogenesis caused embryo-fetal toxicity, decreased fetal weights and a dose-dependent increase in major fetal abnormalities in animals at doses less than the recommended human dose based on body surface area using an estimated daily dose. A similar rat study also showed increased fetal mortality and decreased fetal weights but no major fetal abnormalities at doses less than the recommended human dose based on body surface area using an estimated daily dose (see Data).
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the US general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% - 4% and 15% -20%, respectively.
When administered on day 6 of pregnancy at test dosages of 0.00024 mg/kg, 0.0024 mg/kg, and 0.024 mg/kg (doses less than the recommended human dose) to rabbits, leuprolide acetate produced a dose-related increase in malformations comprised primarily of segmental and fusion defects of the skeleton and skull. Similar studies in rats failed to demonstrate an increase in fetal malformations. There was increased fetal mortality and decreased fetal weights with the two higher doses of leuprolide acetate in rabbits and with the highest dose (0.024 mg/kg) in rats.
There are no data on the presence of leuprolide acetate in either animal or human milk, the effects on the breastfed infants, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for LUPRON DEPOT-PED and any potential adverse effects on the breastfed infant from LUPRON DEPOT-PED or from the underlying maternal condition.
Exclude pregnancy in women of reproductive potential prior to initiating LUPRON DEPOT-PED if clinically indicated [see Use in Specific Populations (8.1)].
LUPRON DEPOT-PED may cause embryo-fetal harm when administered during pregnancy. LUPRON DEPOT-PED is not a contraceptive. If contraception is indicated, advise females of reproductive potential to use a non-hormonal method of contraception during treatment with LUPRON DEPOT-PED [see Use in Specific Populations (8.1)].
Based on its pharmacodynamic effects of decreasing secretion of gonadal steroids, fertility is expected to be decreased while on treatment with LUPRON DEPOT-PED. Clinical and pharmacologic studies in adults (>18 years) with leuprolide acetate and similar analogs have shown reversibility of fertility suppression when the drug is discontinued after continuous administration for periods of up to 24 weeks [see Clinical Pharmacology (12.2)].
There is no evidence that pregnancy rates are affected following discontinuation of LUPRON DEPOT-PED.
Animal studies (prepubertal and adult rats and monkeys) with leuprolide acetate and other GnRH analogs have shown functional recovery of fertility suppression.
The safety and effectiveness of LUPRON DEPOT-PED for the treatment of CPP has been established in pediatric patients 1 years of age and older. Use of LUPRON DEPOT-PED for this indication is supported by evidence from two pivotal, open label clinical studies of 139 pediatric patients with central precocious puberty with an age range of 1 to 11 years [see Clinical Studies (14)]. The safety and effectiveness of LUPRON DEPOT-PED have not been established in pediatric patients less than 1 year old.
No specific antidotes for LUPRON DEPOT-PED are known. Contact Poison Control (1-800-222-1222) for latest recommendations.
In cases of overdosage, standard of care monitoring and management principles should be followed.
LUPRON DEPOT-PED contains active ingredient, leuprolide, in the form of acetate salt, a gonadotropin-releasing hormone (GnRH) agonist. It is a synthetic nonapeptide analog of naturally occurring gonadotropin-releasing hormone (GnRH or LH-RH). The analog possesses greater potency than the natural hormone. The chemical name of leuprolide acetate is 5-oxo-L-prolyl-L-histidyl-L-tryptophyl-L-seryl-L-tyrosyl-D-leucyl-L-leucyl-L-arginyl-N-ethyl-L-prolinamide acetate, which has molecular formula of C59H84N16O12.(C2H4O2)n, n=1 or 2, with the following structural formula:
LUPRON DEPOT-PED for 1-month administration
LUPRON DEPOT-PED is available in a prefilled dual-chamber single-dose syringe containing sterile lyophilized microsphere powder incorporated in a biodegradable lactic acid/glycolid acid copolymer which, when mixed with diluent, becomes a suspension for intramuscular injection. When mixed with 1 mililiter of accompanying diluent, LUPRON DEPOT-PED for 1-month administration is administered as a single-dose intramuscular injection.
The front chamber of LUPRON DEPOT-PED 7.5 mg, 11.25 mg, and 15 mg a prefilled dual-chamber syringe contains leuprolide acetate (7.5/11.25/15 mg), purified gelatin (1.3/1.95/2.6 mg), DL-lactic and glycolic acids copolymer (66.2/99.3/132.4 mg), and D-mannitol (13.2/19.8/26.4 mg). The second chamber of diluent contains carboxymethylcellulose sodium (5 mg), D-mannitol (50 mg), polysorbate 80 (1 mg), water for injection, USP, and glacial acetic acid, USP to control pH.
LUPRON DEPOT-PED 11.25 mg or 30 mg for 3-month administration is available in a prefilled dual-chamber single-dose syringe containing sterile lyophilized microsphere powder incorporated in a biodegradable lactic acid/glycolid acid copolymer which, when mixed with diluent, becomes a suspension for intramuscular injection. When mixed with 1.5 mililiters of accompanying diluent, LUPRON DEPOT-PED for 3-month administration is administered as a single-dose intramuscular injection.
The front chamber of LUPRON DEPOT-PED 11.25 mg for 3-month administration prefilled dual-chamber syringe contains leuprolide acetate (11.25 mg), polylactic acid (99.3 mg) and D-mannitol (19.45 mg). The second chamber of diluent contains carboxymethylcellulose sodium (7.5 mg), D-mannitol (75.0 mg), polysorbate 80 (1.5 mg), water for injection, USP, and glacial acetic acid, USP to control pH.
The front chamber of LUPRON DEPOT-PED 30 mg for 3-month administration prefilled dual-chamber syringe contains leuprolide acetate (30 mg), polylactic acid (264.8 mg) and D-mannitol (51.9 mg). The second chamber of diluent contains carboxymethylcellulose sodium (7.5 mg), D-mannitol (75.0 mg), polysorbate 80 (1.5 mg), water for injection, USP, and glacial acetic acid, USP to control pH.
Leuprolide acetate, a GnRH agonist, acts as a potent inhibitor of gonadotropin secretion (LH and follicle stimulating hormone (FSH)) when given continuously in therapeutic doses.
Following an initial stimulation of GnRH receptors, chronic administration of leuprolide acetate results in downregulation of GnRH receptors, reduction in release of LH and FSH, and consequent suppression of ovarian and testicular production of estradiol and testosterone, respectively. This inhibitory effect is reversible upon discontinuation of drug therapy.
Following a single LUPRON DEPOT-PED 7.5 mg for 1-month administration to adult patients, mean peak leuprolide plasma concentration was almost 20 ng/mL at 4 hours and then declined to 0.36 ng/mL at 4 weeks. However, intact leuprolide and an inactive major metabolite could not be distinguished by the assay which was employed in the study. Nondetectable leuprolide plasma concentrations have been observed during chronic LUPRON DEPOT-PED 7.5 mg administration, but testosterone levels appear to be maintained at castrate levels.
In a study of pediatric patients with CPP, doses of 7.5 mg, 11.25 mg and 15.0 mg of LUPRON DEPOT-PED were given every 4 weeks. In 22 pediatric patients, trough leuprolide plasma levels were determined according to weight categories as summarized below:
LUPRON DEPOT-PED for 3-month administration
Following a single LUPRON DEPOT-PED 11.25 mg or 30 mg for 3-month administration to pediatric patients with CPP, leuprolide concentrations increased with increasing dose with mean peak leuprolide plasma concentration of 19.1 and 52.5 ng/mL at 1 hour for the 11.25 and 30 mg dose levels, respectively. The concentrations then declined to 0.08 and 0.25 ng/mL at 2 weeks after dosing for the 11.25 and 30 mg dose levels. Mean leuprolide plasma concentration remained constant from month 1 to month 3 for both 11.25 and 30 mg doses. The mean leuprolide concentrations 3 months after the first and second injections were similar indicating no accumulation of leuprolide from repeated administration.
The mean steady-state volume of distribution of leuprolide following intravenous bolus administration to healthy male subjects was 27 L. In vitro binding to human plasma proteins ranged from 43% to 49%.
In healthy male subjects given an intravenous 1 mg bolus of leuprolide the mean systemic clearance was 7.6 L/h, with a terminal elimination half-life of approximately 3 hours based on a two-compartment model.
In rats and dogs, administration of 14C-labeled leuprolide was shown to be metabolized to smaller inactive peptides; a pentapeptide (Metabolite I), tripeptides (Metabolites II and III) and a dipeptide (Metabolite IV). These fragments may be further catabolized.
The major metabolite (M-I) plasma concentrations measured in 5 prostate cancer patients reached maximum concentration 2 to 6 hours after dosing and were approximately 6% of the peak parent drug concentration. One week after dosing, mean plasma M-I concentrations were approximately 20% of mean leuprolide concentrations.
Following administration of LUPRON DEPOT 3.75 mg to 3 patients, less than 5% of the dose was recovered as parent and M-I metabolite in the urine.
The pharmacokinetics of LUPRON DEPOT-PED has not been determined in patients with hepatic or renal impairment.
No pharmacokinetic-based drug-drug interaction studies have been conducted with LUPRON DEPOT-PED. Leuprolide acetate is a peptide that is not degraded by cytochrome P-450 enzymes; hence, drug interactions associated with cytochrome P-450 enzymes would not be expected to occur.
A two-year carcinogenicity study was conducted in rats and mice. In rats, a dose-related increase of benign pituitary hyperplasia and benign pituitary adenomas was noted at 24 months when the drug was administered subcutaneously at high daily doses (0.6 to 4 mg/kg). There was a significant but not dose-related increase of pancreatic islet-cell adenomas in females and of testicular interstitial cell adenomas in males (highest incidence in the low dose group). In mice, no leuprolide acetate-induced tumors or pituitary abnormalities were observed at a dose as high as 60 mg/kg for two years.
Mutagenicity studies have been performed with leuprolide acetate using bacterial and mammalian systems. These studies provided no evidence of a mutagenic potential.
The efficacy of LUPRON DEPOT-PED was evaluated in a pivotal open-label, multicenter clinical trial in which 55 pediatric patients with central precocious puberty (49 females and 6 males, naïve to previous GnRHa treatment) were treated with LUPRON DEPOT-PED 1-month formulations until age was appropriate for entry into puberty (see treatment period data below)and a subset of 40 subjects were then followed post-treatment (see follow-up period data below). The mean ± SD age at the start of treatment was 7 ± 2 years and the duration of treatment was 4 ± 2 years. Study drug was administered intramuscularly (IM) every 28 days, with incremental adjustments of 3.75mg at each clinic visit, if necessary based on clinical and laboratory results. During the follow-up period, GnRHa stimulation test was performed every 6 months until a pubertal response was observed.
During the treatment period, LUPRON DEPOT-PED suppressed gonadotropins and sex steroids to prepubertal levels. Suppression of peak stimulated LH concentrations to < 1.75 mIU/mL was achieved in 96% of subjects by month 1. Five subjects required increased doses of study drug to achieve or retain LH suppression. The number and percentage of subjects with suppression of peak stimulated LH < 1.75 mIU/mL and mean ± SD peak stimulated LH over time is shown in Table 4. Six months after the treatment period was finished, the mean peak stimulated LH was 20.6 ± SD 13.7 mIU/mL (n=30).
The following effects have been noted with the chronic administration of leuprolide: cessation of menses (in girls), normalization and stabilization of linear growth and bone age advancement, stabilization of clinical signs and symptoms of puberty.
Suppression (defined as regression or no change) of the clinical/physical signs of puberty was achieved in most patients. In females, suppression of breast development ranged from 66.7 to 90.6% of subjects during the first 5 years of treatment. The mean stimulated estradiol was 15.1 pg/mL at baseline, decreased to the lower level of detection (5.0 pg/mL) by Week 4 and was maintained there during the first 5 years of treatment. In males, suppression of genitalia development ranged from 60% to 100% of subjects during the first 5 years of treatment. The mean stimulated testosterone was 347.7 ng/dL at baseline and was maintained at levels no greater than 25.3 ng/dL during the first 5 years of treatment.
A “flare effect” of transient bleeding or spotting during the first 4 weeks of treatment was observed in 19.4% (7/36) females who had not reached menarche at baseline. After the first 4 weeks and for the remainder of the treatment period, no subject reported menstrual-like bleeding, and only rare spotting was noted.
The mean ratio of bone age to chronological age decreased from 1.5 at baseline to 1.1 by end of treatment. The mean height standard deviation z-score changed from 1.6 at baseline to 0.7 at the end of the treatment phase.
Thirty five (35) females and 5 males participated in a post-treatment follow-up period to assess reproductive function (in females) and final height. At 6 months post-treatment, most patients reverted to pubertal levels of LH (87.9%) and clinical signs of resumption of pubertal progression were evident with increase in breast development in girls (66.7%) and increase in genitalia development in boys (80%).
After stopping treatment, regular menses were reported for all female subjects who reached 12 years of age during follow-up; mean time to menses was approximately 1.5 years; mean age of onset of menstruation after stopping treatment was 12.9 years.
Of the 40 patients evaluated in the follow-up, 33 were observed until they reached final or near-final adult height. These patients had a mean increase in final adult height compared to baseline predicted adult height. The mean final adult height standard deviation score was -0.2.
The efficacy was evaluated in a 6-month, randomized, open-label clinical study of LUPRON DEPOT-PED 3-Month formulations. 84 subjects (76 female, 8 male) between 1 and 11 years of age received the LUPRON DEPOT-PED 11.25 mg or 30 mg for 3-month administration formulation. Each dose group had an equal number of treatment-naïve patients who had pubertal LH levels and patients previously treated with GnRHa therapies who had prepubertal LH levels at the time of study entry. The percentage of subjects with suppression of peak-stimulated LH to < 4.0 mIU/mL, as determined by assessments at months 2, 3 and 6, is 78.6% in the 11.25 mg dose and 95.2% in the 30 mg dose as shown in Table 5.
a. Previously treated with GnRHa for at least 6 months prior to enrollment in pivotal Study L-CP07-167.
The mean peak stimulated LH levels for all visits are shown by dose and subgroup (naïve vs. previously treated subjects) in Figures 1 and 2.
Figure 1. Mean Peak Stimulated LH for LUPRON DEPOT-PED 11.25 mg for 3-month administration
Figure 2. Mean Peak Stimulated LH for LUPRON DEPOT-PED 30 mg for 3-month administration
For the LUPRON DEPOT-PED 11.25 mg dose for 3-month administration, 93% (39/42) of subjects and for LUPRON DEPOT-PED 30 mg dose for 3-month administration, 100% (42/42) of subjects had sex steroid (estradiol or testosterone) suppressed to prepubertal levels at all visits. Clinical suppression of puberty in female patients was observed in 29 of 32 (90.6%) and 28 of 34 (82.4%) of patients in the 11.25 mg and 30 mg groups, respectively, at month 6. Clinical suppression of puberty in males was observed in 1 of 2 (50%) and 2 of 5 (40%) patients in the 11.25 mg and 30 mg groups, respectively, at month 6. In subjects with complete data for bone age, 29 of 33 (88%) in the 11.25 mg group and 30 of 40 in the 30 mg group (75%) had a decrease in the ratio of bone age to chronological age at month 6 compared to screening.
LUPRON DEPOT-PED for depot suspension is supplied in a single dose, prefilled dual-chamber syringe containing a white lyophilized powder and a colorless diluent for reconstitution:
Each kit contains:
Prior to reconstitution, store at 25°C (77°F); excursions permitted to 15-30°C (59-86°F) [See USP Controlled Room Temperature].
After reconstitution, use immediately [see Dosage and Administration (2.4, 2.5)].
Advise the patient to read the FDA-approved patient labeling (Medication Guide).
Symptoms After Initial LUPRON DEPOT-PED Administration
Inform patients and caregivers that during the early phase of therapy with LUPRON DEPOT-PED, gonadotropins and sex steroids rise above baseline because of the initial stimulatory effect of the drug. Therefore, an increase in clinical signs and symptoms of puberty may be observed. Instruct patients and caregivers to notify the physician if these symptoms continue beyond the second month after LUPRON DEPOT-PED administration [see Warnings and Precautions (5.1)].
Inform patients and caregivers that psychiatric events have been reported in patients taking GnRH agonists, including leuprolide acetate. Events include emotional lability, such as crying, irritability, impatience, anger, and aggression. Instruct patients and caregivers to monitor for development or worsening of psychiatric symptoms including depression during treatment with LUPRON DEPOT-PED [see Warnings and Precautions (5.2)].
Inform patients and caregivers that reports of convulsions have been observed in patients receiving GnRH agonists, including leuprolide acetate. Patients with a history of seizures, epilepsy, cerebrovascular disorders, central nervous system anomalies or tumors, and patients on concomitant medications that have been associated with convulsions may be at increased risk [see Warnings and Precautions (5.3)].
Injection Site Reactions
Inform patients and caregivers that injection site related adverse reactions may occur such as transient burning/stinging, pain, bruising, and redness. Advise patients to contact their healthcare provider if they experience rash or severe injection site reactions [see Adverse Reactions (6.1)].
LUPRON DEPOT-PED is contraindicated in pregnancy. If the patient becomes pregnant while taking the drug, the patient should be informed of the potential risk to the fetus [see Use in Specific Populations (8.1)].
Compliance with the Dosing Schedule
Inform caregivers about the importance of adherence to the LUPRON DEPOT-PED dosing schedule [see Dosage and Administration (2.2, 2.3)].
