⏳ Availability & generic status
FDA-approved generic versions are listed, and recent pricing/market data suggests they may be available — see Therapeutic equivalents.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE ELIGARD ® is indicated for the palliative treatment of advanced prostate cancer. ELIGARD ® is a gonadotropin releasing hormone (GnRH) agonist indicated for the palliative treatment of advanced prostate cancer ( 1 )
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION ELIGARD ® is administered subcutaneously and provides continuous release of leuprolide acetate over a one-, three-, four-, or six-month treatment period (Table 1). The injection delivers the dose of leuprolide acetate incorporated in a polymer formulation. Table 1.
ELIGARD ® Recommended Dosing Dosage 7.5 mg 22.5 mg 30 mg 45 mg Recommended dose 1 injection every month 1 injection every 3 months 1 injection every 4 months 1 injection every 6 months As with other drugs administered by subcutaneous injection, the injection site should vary periodically. The specific injection location should be an area with sufficient soft or loose subcutaneous tissue. In clinical trials, the injections were administered in the upper- or mid-abdominal area.
Avoid areas with brawny or fibrous subcutaneous tissue or locations that could be rubbed or compressed (i.e., with a belt or clothing waistband). 7.5 mg subcutaneously every month ( 2 ) 22.5 mg subcutaneously every 3 months ( 2 ) 30 mg subcutaneously every 4 months ( 2 ) 45 mg subcutaneously every 6 months ( 2 )
2.1Mixing Procedure Use aseptic technique throughout the procedure. As with other similar agents, the use of gloves is recommended during mixing and administration. 1 Allow the product to reach room temperature before mixing.
Once mixed, the product must be administered within 30 minutes or it should be discarded. ELIGARD ® is packaged in a carton containing two thermoformed trays and this package insert: Table 2: Contents of the Two Trays in the ELIGARD ® Carton Syringe A Tray Syringe B Tray Syringe A pre-filled with the ATRIGEL ® Delivery System Syringe B pre-filled with the leuprolide acetate powder Long white plunger rod Safety needle Desiccant pack Desiccant pack Follow the detailed instructions below to ensure correct preparation of ELIGARD ® prior to administration: 1.
On a clean field, open both trays by tearing off the foil from the corners and removing the contents. Discard the desiccant pack(s). Open the safety needle package by peeling back the paper tab.
2. Pull out (do not unscrew) the short blue plunger rod with attached gray stopper from Syringe B and discard. 3.
Gently screw the white plunger rod into the remaining gray stopper in Syringe B. 4. Unscrew and discard the clear cap from Syringe A.
5. Remove and discard the gray rubber cap from Syringe B. 6.
Join the two syringes together by pushing and gently screwing until secure. 7. Inject the liquid contents of Syringe A into the leuprolide acetate powder contained in Syringe B.
Thoroughly mix the product for approximately 45 seconds by pushing the contents back and forth between both syringes to obtain a uniform suspension. When thoroughly mixed, the suspension will appear light tan to tan (ELIGARD ® 7.5 mg) or colorless to pale yellow (ELIGARD ® 22.5 mg, 30 mg and 45 mg). Note: Product must be mixed as described; shaking will NOT provide adequate mixing.
8. After mixing, hold the syringes vertically (upright) with Syringe B (short, wide syringe) on the bottom. The syringes should remain securely coupled.
Draw all of the mixed product into Syringe B by depressing the Syringe A plunger and slightly withdrawing the Syringe B plunger. 9. Unscrew Syringe A to decouple the syringes while continuing to push down on the Syringe A plunger.
Note: Small air bubbles will remain in the formulation – this is acceptable. 10. Continue to hold Syringe B upright with the open end at the top.
Hold back the white plunger on Syringe B to prevent loss of the product and attach the safety needle cartridge. Gently screw clockwise with approximately a three-quarter turn until the needle is secure. Do not overtighten, as the hub may become damaged resulting in leakage of the product during injection .
The safety sheath may also be damaged if the needle is screwed with too much force. 11. (1) Move the safety sheath away from the needle and towards the syringe and (2) pull off the clear needle cartridge cover immediat…

⛔ Contraindications ▾
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. Known hypersensitivity to GnRH, GnRH agonist analogs or any of the components of ELIGARD ® ( 4.1 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Tumor Flare: Transient increase in serum levels of testosterone during treatment may result in worsening of symptoms or onset of new signs and symptoms during the first few weeks of treatment, including bone pain, neuropathy, hematuria, bladder outlet obstruction, ureteral obstruction, or spinal cord compression. Monitor patients at risk closely and manage as appropriate. ( 5.1 , 5.2 ) Hyperglycemia and diabetes: Hyperglycemia and an increased risk of developing diabetes have been reported in men receiving GnRH analogs.
Monitor blood glucose level and manage according to current clinical practice. ( 5.3 ) Cardiovascular diseases: Increased risk of myocardial infarction, sudden cardiac death and stroke has been reported in men. Monitor for cardiovascular disease and manage according to current clinical practice.
( 5.4 ) Effect on QT/QTc Interval: Androgen deprivation therapy may prolong the QT interval. Consider risks and benefits. ( 5.5 ) Embryo-Fetal Toxicity: May cause fetal harm.
(5.6, 8.1) Convulsions have been observed in patients with or without a history of predisposing factors. Manage convulsions according to the current clinical practice. (5.7)
5.1Tumor 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.
5.2Laboratory 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.
5.3Hyperglycemia 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 man…
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS Most common adverse reactions in clinical studies (incidence ≥ 5%): Malaise, fatigue, hot flashes/sweats, and testicular atrophy. ( 6.1 ) As with other GnRH agonists, other adverse reactions, including decreased bone density and rare cases of pituitary apoplexy have been reported. ( 6.1 , 6.2 ) To report SUSPECTED ADVERSE REACTIONS, contact Tolmar Pharmaceuticals, Inc. at 1-888-354-4273 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
6.1Clinical 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.

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.

8 USE IN SPECIFIC POPULATIONS Females and males of reproductive potential: ELIGARD ® may impair fertility. ( 8.3 ) Safety and effectiveness in pediatric patients have not been established ( 8.4 )
8.1Pregnancy 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.
8.2Lactation 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.
8.3Females 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 )] .

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism 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.
12.2Pharmacodynamics 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.
12.3Pharmacokinetics 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 (C max ) at approximately 5 hours after injection. After the initial increase following each injection, serum concentrations remained relatively constant (0.28 – 2.00 ng/mL).

🧬 Mechanism of Action ▾
12.1Mechanism 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.

📋 Description ▾
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).
