4  CONTRAINDICATIONS

Hypersensitivity

ELIGARD® is contraindicated in patients with hypersensitivity to GnRH, GnRH agonist analogs or any of the components of ELIGARD®.  Anaphylactic reactions to synthetic GnRH or GnRH agonist analogs have been reported in the literature.

5  WARNINGS AND PRECAUTIONS

5.1 Tumor Flare

ELIGARD® 7.5 mg 22.5 mg 30 mg, like other GnRH agonists, causes a transient increase in serum concentrations of testosterone during the first week of treatment. ELIGARD® 45 mg causes a transient increase in serum concentrations of testosterone during the first two weeks of treatment.  Patients may experience worsening of symptoms or onset of new signs and symptoms during the first few weeks of treatment, including bone pain, neuropathy, hematuria, or bladder outlet obstruction.

Cases of ureteral obstruction and/or spinal cord compression, which may contribute to paralysis with or without fatal complications, have been observed in the palliative treatment of advanced prostate cancer using GnRH agonists.

Patients with metastatic vertebral lesions and/or with urinary tract obstruction should be closely observed during the first few weeks of therapy. If spinal cord compression or ureteral obstruction develops, standard treatment of these complications should be instituted.

5.2 Laboratory Tests

Response to ELIGARD® should be monitored by periodic measurement of serum concentrations of testosterone and prostate specific antigen.

In the majority of patients, testosterone levels increased above Baseline during the first week, declining thereafter to Baseline levels or below by the end of the second or third week.  Castrate levels were generally reached within two to four weeks.

Castrate testosterone levels were maintained for the duration of the treatment with ELIGARD® 7.5 mg.  No increases to above the castrate level occurred in any of the patients.

Castrate levels were generally maintained for the duration of treatment with ELIGARD® 22.5 mg.

Once castrate levels were achieved with ELIGARD® 30 mg, most (86/89) patients remained suppressed throughout the study.

Once castrate levels were achieved with ELIGARD® 45 mg, only one patient (< 1%) experienced a breakthrough, with testosterone levels > 50 ng/dL.

Results of testosterone determinations are dependent on assay methodology.  It is advisable to be aware of the type and precision of the assay methodology to make appropriate clinical and therapeutic decisions.

Drug/Laboratory Test Interactions:  Therapy with leuprolide acetate results in suppression of the pituitary-gonadal system.  Results of diagnostic tests of pituitary gonadotropic and gonadal functions conducted during and after leuprolide therapy may be affected.

5.3 Hyperglycemia and Diabetes

Hyperglycemia and an increased risk of developing diabetes have been reported in men receiving GnRH agonists. Hyperglycemia may represent development of diabetes mellitus or worsening of glycemic control in patients with diabetes. Monitor blood glucose and/or glycosylated hemoglobin (HbA1c) periodically in patients receiving a GnRH agonist and manage with current practice for treatment of hyperglycemia or diabetes.

5.4 Cardiovascular Diseases

Increased risk of developing myocardial infarction, sudden cardiac death and stroke has been reported in association with use of GnRH agonists in men. The risk appears low based on the reported odds ratios, and should be evaluated carefully along with cardiovascular risk factors when determining a treatment for patients with prostate cancer. Patients receiving a GnRH agonist should be monitored for symptoms and signs suggestive of development of cardiovascular disease and be managed according to current clinical practice.

5.5 Effect on QT/QTc Interval

Androgen deprivation therapy may prolong the QT/QTc interval. Providers should consider whether the benefits of androgen deprivation therapy outweigh the potential risks in patients with congenital long QT syndrome, congestive heart failure, frequent electrolyte abnormalities, and in patients taking drugs known to prolong the QT interval. Electrolyte abnormalities should be corrected. Consider periodic monitoring of electrocardiograms and electrolytes.

5.6 Embryo-Fetal Toxicity

Based on findings in animal studies and mechanism of action, leuprolide acetate may cause fetal harm when administered to a pregnant woman. In animal developmental and reproductive studies, major fetal abnormalities were observed after administration of leuprolide acetate throughout gestation in rats. Advise pregnant patients and females of reproductive potential of the potential risk to the fetus [see Use in Specific Populations (8.1), Clinical Pharmacology (12.1)].

5.7 Convulsions

Postmarketing reports of convulsions have been observed in patients on leuprolide acetate therapy. These included patients with a history of seizures, epilepsy, cerebrovascular disorders, central nervous system anomalies or tumors, and in 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. Patients receiving a GnRH agonist who experience convulsion should be managed according to current clinical practice.

6  ADVERSE REACTIONS

6.1 Clinical Trial Experience

The safety of all ELIGARD® formulations was evaluated in clinical trials involving patients with advanced prostate cancer.  In addition, the safety of ELIGARD® 7.5 mg was evaluated in 8 surgically castrated males (Table 5).  ELIGARD®, like other GnRH analogs, caused a transient increase in serum testosterone concentrations during the first one to two weeks of treatment.  Therefore, potential exacerbations of signs and symptoms of the disease during the first weeks of treatment are of concern in patients with vertebral metastases and/or urinary obstruction or hematuria.  If these conditions are aggravated, it may lead to neurological problems such as weakness and/or paresthesia of the lower limbs or worsening of urinary symptoms [see WARNINGS AND PRECAUTIONS (5.2)].

During the clinical trials, injection sites were closely monitored.  Refer to Table 4 for a summary of reported injection site events.

Erythema was reported following 2 injections of ELIGARD® 22.5 mg. One report characterized the erythema as mild and it resolved within 7 days. The other report characterized the erythema as moderate and it resolved within 15 days. Neither patient experienced erythema at multiple injection times. A single event reported as moderate pain resolved within two minutes and all 3 mild pain events resolved within several days following injection of ELIGARD® 30 mg. Following injection of ELIGARD® 30 mg, three of the 35 burning/stinging events were reported as moderate. Transient pain was reported as mild in intensity in nine of ten (90%) events and moderate in intensity in one of ten (10%) events following injection of ELIGARD® 45 mg. Mild bruising was reported following 5 (2.3%) study injections and moderate bruising was reported following 2 (<1%) study injections of ELIGARD® 45 mg.

These localized adverse events were non-recurrent over time.  No patient discontinued therapy due to an injection site adverse event.

The following possibly or probably related systemic adverse events occurred during clinical trials with ELIGARD®, and were reported in > 2% of patients (Table 5).  Often, causality is difficult to assess in patients with metastatic prostate cancer.  Reactions considered not drug-related are excluded.

Changes in Bone Density:  Decreased bone density has been reported in the medical literature in men who have had orchiectomy or who have been treated with a GnRH agonist analog.  It can be anticipated that long periods of medical castration in men will have effects on bone density.

6.2 Postmarketing Experience

Pituitary apoplexy-During post-marketing surveillance, rare cases of pituitary apoplexy (a clinical syndrome secondary to infarction of the pituitary gland) have been reported after the administration of gonadotropin-releasing hormone agonists. In a majority of these cases, a pituitary adenoma was diagnosed with a majority of pituitary apoplexy cases occurring within 2 weeks of the first dose, and some within the first hour. In these cases, pituitary apoplexy has presented as sudden headache, vomiting, visual changes, ophthalmoplegia, altered mental status, and sometimes cardiovascular collapse. Immediate medical attention has been required.

7  DRUG INTERACTIONS

No pharmacokinetic drug-drug interaction studies were conducted with ELIGARD®.

8  USE IN SPECIFIC POPULATIONS

8.1  Pregnancy

Risk Summary
Based on findings in animal studies and mechanism of action, ELIGARD® may cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)]. There are no available data in pregnant women to inform the drug-associated risk. Expected hormonal changes that occur with ELIGARD® treatment increase the risk for pregnancy loss. In animal developmental and reproductive studies, major fetal abnormalities were observed after administration of leuprolide acetate throughout gestation in rats. Advise pregnant patients and females of reproductive potential of the potential risk to the fetus (see Data).

Animal Data
In animal developmental and reproductive studies, major fetal abnormalities were observed after administration of leuprolide acetate throughout gestation.  There were increased fetal mortality and decreased fetal weights in rats and rabbits.  The effects of fetal mortality are expected consequences of the alterations in hormonal levels brought about by this drug.

8.2 Lactation

The safety and efficacy of ELIGARD® have not been established in females. There is no information regarding the presence of ELIGARD® in human milk, the effects on the breastfed child, or the effects on milk production. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in a breastfed child from ELIGARD®, a decision should be made to discontinue breastfeeding or discontinue the drug, taking into account the importance of the drug to the mother.

8.3  Females and Males of Reproductive Potential 

Infertility
Males
Based on mechanism of action, ELIGARD® may impair fertility in males of reproductive potential [see Clinical Pharmacology (12.1)].

8.4  Pediatric Use

The safety and effectiveness of ELIGARD® in pediatric patients have not been established.

8.5  Geriatric Use

The majority of the patients (approximately 70%) studied in the clinical trials were age 70 and older.

10  OVERDOSAGE

In clinical trials using daily subcutaneous injections of leuprolide acetate in patients with prostate cancer, doses as high as 20 mg/day for up to two years caused no adverse effects differing from those observed with the 1 mg/day dose.

11  DESCRIPTION

ELIGARD® is a sterile polymeric matrix formulation of leuprolide acetate, a GnRH agonist, for subcutaneous injection.  It is designed to deliver leuprolide acetate at a controlled rate over a one-, three-, four- or six-month therapeutic period.

Leuprolide acetate is a synthetic nonapeptide analog of naturally occurring gonadotropin releasing hormone (GnRH) that, when given continuously, inhibits pituitary gonadotropin secretion and suppresses testicular and ovarian steroidogenesis.  The analog possesses greater potency than the natural hormone.  The chemical name is 5-oxo-L-prolyl-L-histidyl-L-tryptophyl-L-seryl-L-tyrosyl-D-leucyl-L-leucyl-L-arginyl-N-ethyl-L-prolinamide acetate (salt) with the following structural formula:

ELIGARD® is prefilled and supplied in two separate, sterile syringes whose contents are mixed immediately prior to administration.  The two syringes are joined and the single dose product is mixed until it is homogenous.  ELIGARD® is administered subcutaneously, where it forms a solid drug delivery depot.

One syringe contains the ATRIGEL® Delivery System and the other contains leuprolide acetate.  ATRIGEL® is a polymeric (non-gelatin containing) delivery system consisting of a biodegradable poly (DL-lactide-co-glycolide) (PLGH or PLG) polymer formulation dissolved in a biocompatible solvent, N-methyl-2-pyrrolidone (NMP).

Refer to Table 6 for the delivery system composition and reconstituted product formulation for each ELIGARD® product.

12  CLINICAL PHARMACOLOGY

12.1  Mechanism of Action

Leuprolide acetate, a gonadotropin releasing hormone (GnRH) agonist, acts as a potent inhibitor of gonadotropin secretion when given continuously in therapeutic doses.  Animal and human studies indicate that after an initial stimulation, chronic administration of leuprolide acetate results in suppression of testicular and ovarian steroidogenesis.  This effect is reversible upon discontinuation of drug therapy.

In humans, administration of leuprolide acetate results in an initial increase in circulating levels of luteinizing hormone (LH) and follicle stimulating hormone (FSH), leading to a transient increase in levels of the gonadal steroids (testosterone and dihydrotestosterone in males, and estrone and estradiol in premenopausal females).  However, continuous administration of leuprolide acetate results in decreased levels of LH and FSH.  In males, testosterone is reduced to below castrate threshold (≤50 ng/dL).  These decreases occur within two to four weeks after initiation of treatment.  Long-term studies have shown that continuation of therapy with leuprolide acetate maintains testosterone below the castrate level for up to seven years.

12.2  Pharmacodynamics

Following the first dose of ELIGARD®, mean serum testosterone concentrations transiently increased, then fell to below castrate threshold (≤ 50 ng/dL) within three weeks for all ELIGARD® concentrations.

Continued monthly treatment with ELIGARD® 7.5 mg maintained castrate testosterone suppression throughout the study.  No breakthrough of testosterone concentrations above castrate threshold (> 50 ng/dL) occurred at any time during the study once castrate suppression was achieved (Figure 1).

One patient received less than a full dose of ELIGARD® 22.5 mg at baseline, never suppressed and withdrew from the study at Day 73.  Of the 116 patients remaining in the study, 115 (99%) had serum testosterone levels below the castrate threshold by Month 1 (Day 28).  By Day 35, 116 (100%) had serum testosterone levels below the castrate threshold.  Once testosterone suppression was achieved, one patient (< 1%) demonstrated breakthrough (concentrations > 50 ng/dL after achieving castrate levels) following the initial injection; that patient remained below the castrate threshold following the second injection (Figure 2).

One patient withdrew from the ELIGARD® 30 mg study at Day 14.  Of the 89 patients remaining in the study, 85 (96%) had serum testosterone levels below the castrate threshold by Month 1 (Day 28).  By Day 42, 89 (100%) of patients attained castrate testosterone suppression.  Once castrate testosterone suppression was achieved, three patients (3%) demonstrated breakthrough (concentrations > 50 ng/dL after achieving castrate levels) (Figure 3).

One patient at Day 1 and another patient at Day 29 were withdrawn from the ELIGARD® 45 mg study.  Of the 109 patients remaining in the study, 108 (99.1%) had serum testosterone levels below the castrate threshold by Month 1 (Day 28).  One patient did not achieve castrate suppression and was withdrawn from the study at Day 85.  Once castrate testosterone suppression was achieved, one patient (< 1%) demonstrated breakthrough (concentrations > 50 ng/dL after achieving castrate levels) (Figure 4).

Leuprolide acetate is not active when given orally.

12.3  Pharmacokinetics   

Absorption

ELIGARD® 7.5 mg
The pharmacokinetics/pharmacodynamics observed during three once-monthly injections in 20 patients with advanced prostate cancer is shown in Figure 1.  Mean serum leuprolide concentrations following the initial injection rose to 25.3 ng/mL (Cmax) at approximately 5 hours after injection.  After the initial increase following each injection, serum concentrations remained relatively constant (0.28 – 2.00 ng/mL).

Figure 1. Pharmacokinetic/Pharmacodynamic Response (N=20) to ELIGARD® 7.5 mg – Patients Dosed Initially and at Months 1 and 2

A reduced number of sampling time points resulted in the apparent decrease in Cmax values with the second and third doses of ELIGARD® 7.5 mg (Figure 1).

ELIGARD® 22.5 mg
The pharmacokinetics/pharmacodynamics observed during two injections every three months (ELIGARD® 22.5 mg) in 22 patients with advanced prostate cancer is shown in Figure 2.  Mean serum leuprolide concentrations rose to 127 ng/mL and 107 ng/mL at approximately 5 hours following the initial and second injections, respectively.  After the initial increase following each injection, serum concentrations remained relatively constant (0.2 – 2.0 ng/mL).

ELIGARD® 45 mg
The pharmacokinetics/pharmacodynamics observed during injections administered initially and at six months (ELIGARD® 45 mg) in 27 patients with advanced prostate cancer is shown in Figure 4.  Mean serum leuprolide concentrations rose to 82 ng/mL and 102 ng/mL (Cmax) at approximately 4.5 hours following the initial and second injections, respectively. After the initial increase following each injection, mean serum concentrations remained relatively constant (0.2 – 2.0 ng/mL).

There was no evidence of significant accumulation during repeated dosing.  Non-detectable leuprolide plasma concentrations have been occasionally observed during ELIGARD® administration, but testosterone levels were maintained at castrate levels.

Distribution.  The mean steady-state volume of distribution of leuprolide following intravenous bolus administration to healthy male volunteers was 27 L. In vitro binding to human plasma proteins ranged from 43% to 49%.

Metabolism.  In healthy male volunteers, a 1-mg bolus of leuprolide administered intravenously revealed that the mean systemic clearance was 8.34 L/h, with a terminal elimination half-life of approximately 3 hours based on a two compartment model.

No drug metabolism study was conducted with ELIGARD®.  Upon administration with different leuprolide acetate formulations, the major metabolite of leuprolide acetate is a pentapeptide (M-1) metabolite.

Excretion.  No drug excretion study was conducted with ELIGARD®.

Geriatrics. [see USE IN SPECIAL POPULATIONS (8.5)]

Race.  In patients studied, mean serum leuprolide concentrations were similar regardless of race.  Refer to Table 7 for distribution of study patients by race.

13  NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Two-year carcinogenicity studies were conducted with leuprolide acetate 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. Patients have been treated with leuprolide acetate for up to three years with doses as high as 10 mg/day and for two years with doses as high as 20 mg/day without demonstrable pituitary abnormalities. No carcinogenicity studies have been conducted with ELIGARD®.

Mutagenicity studies have been performed with leuprolide acetate using bacterial and mammalian systems and with ELIGARD® 7.5 mg in bacterial systems.  These studies provided no evidence of a mutagenic potential.

14  CLINICAL STUDIES

One open-label, multicenter study was conducted with each ELIGARD® formulation (7.5 mg, 22.5 mg, 30 mg, and 45 mg) in patients with Jewett stage A though D prostate cancer who were treated with at least a single injection of study drug (Table 8).  These studies evaluated the achievement and maintenance of castrate serum testosterone suppression over the duration of therapy (Figures 5-8).

During the AGL9904 study using ELIGARD® 7.5 mg, once testosterone suppression  was achieved, no patients (0%) demonstrated breakthrough (concentration > 50 ng/dL) at any time in the study.

During the AGL9909 study using ELIGARD® 22.5 mg, once testosterone suppression was achieved, only one patient (< 1%) demonstrated breakthrough following the initial injection; that patient remained below the castrate threshold following the second injection.

During the AGL0001 study using ELIGARD® 30 mg, once testosterone suppression was achieved, three patients (3%) demonstrated breakthrough.  In the first of these patients, a single serum testosterone concentration of 53 ng/dL was reported on the day after the second injection.  In this patient, castrate suppression was reported for all other time points.  In the second patient, a serum testosterone concentration of 66 ng/dL was reported immediately prior to the second injection.  This rose to a maximum concentration of 147 ng/dL on the second day after the second injection.  In this patient, castrate suppression was again reached on the seventh day after the second injection and was maintained thereafter.  In the final patient, serum testosterone concentrations > 50 ng/dL were reported at 2 and at 8 hours after the second injection.  Serum testosterone concentration rose to a maximum of 110 ng/dL on the third day after the second injection.  In this patient, castrate suppression was again reached eighteen days after the second injection and was maintained until the final day of the study, when a single serum testosterone concentration of 55 ng/dL was reported.

During the AGL0205 study using ELIGARD® 45 mg, once testosterone suppression was achieved, one patient (<1%) demonstrated breakthrough.  This patient reached castrate suppression at Day 21 and remained suppressed until Day 308 when his testosterone level rose to 112 ng/dL.  At Month 12 (Day 336), his testosterone was 210 ng/dL.

Two patients withdrew for reasons unrelated to drug. One patient received less than a full dose at Baseline, never suppressed, and was withdrawn at Day 73 and given an alternate treatment. All non-evaluable patients who attained castration by Day 28 maintained castration at each time point up to and including the time of withdrawal. One patient withdrew on Day 14. All 7 non-evaluable patients who had achieved castration by Day 28 maintained castration at each time point, up to and including the time of withdrawal. Two patients were withdrawn prior to the Month 1 blood draw. One patient did not achieve castration and was withdrawn on Day 85. All 5 non-evaluable patients who attained castration by Day 28, maintained castration at each time point up to and including the time of withdrawal.
