INDICATIONS AND USAGE

LUPANETA PACK contains leuprolide acetate, a gonadotropin-releasing hormone (GnRH) agonist and norethindrone acetate, a progestin, and is indicated for:

  • Initial management of the painful symptoms of endometriosis (1)
  • Management of recurrence of symptoms (1)

Limitations of Use:

  • The total duration of therapy with LUPANETA PACK should not exceed 12 months due to concerns about the adverse impact on bone mineral density (BMD).(1, 2.1, 5.1)

DOSAGE AND ADMINISTRATION

  • Do not administer leuprolide acetate for depot suspension in the LUPANETA PACK alone if the patient is not taking norethindrone acetate. (2.1)
  • Do not administer leuprolide acetate for depot suspension 11.25 mg more frequently than every 3 months. (2.1)
  • Do not administer a fractional dose of leuprolide acetate for depot suspension 11.25 mg. Do not substitute the leuprolide acetate for depot suspension 11.25 mg (3 months of therapy) component for the leuprolide acetate for depot suspension 3.75 mg (one month of therapy) component of the LUPANETA PACK; they are not equivalent due to the different release characteristics. (2.1)
  • The recommended dosage is leuprolide acetate for depot suspension 11.25 mg for 3-month administration given by a healthcare provider as a single intramuscular (IM) injection every 3 months for up to two injections (6 months of therapy) co-administered with norethindrone acetate 5 mg tablets taken orally once daily by the patient for up to 6 months. If endometriosis symptoms recur after initial course of therapy, consider retreatment for up to another six months. (2.2)
  • Reconstitute leuprolide acetate prior to use. See the full prescribing information for preparation and administration instructions. (2.3)

DOSAGE FORMS AND STRENGTHS

  • For injection: Leuprolide acetate for depot suspension 11.25 mg lyophilized powder for reconstitution in a dual-chamber syringe (3
  • Tablets: Norethindrone acetate 5 mg (3)

CONTRAINDICATIONS

  • Hypersensitivity to GnRH, GnRH agonist or any of the excipients in leuprolide acetate for depot suspension or norethindrone acetate (4)
  • Undiagnosed abnormal uterine bleeding (4)
  • Pregnancy (4, 8.1)
  • Known, suspected or history of breast or other hormone-sensitive cancer (4)
  • Thrombotic or thromboembolic disorders (4)
  • Liver tumors or liver disease (4)

WARNINGS AND PRECAUTIONS

  • Loss of bone mineral density (BMD): Duration of treatment is limited by risk of bone mineral density loss. When using LUPANETA PACK for the management of endometriosis, the norethindrone acetate component of the LUPANETA PACK reduces the BMD loss. Do not retreat with leuprolide acetate for depot suspension alone. Assess BMD after 6 months of treatment before retreatment. Do not use for more than 12 months due to concerns about adverse impact on BMD. (5.1)
  • Embryo-Fetal Toxicity: May cause fetal harm. Exclude pregnancy before initiating treatment if clinically indicated and discontinue use if pregnancy occurs. Use non-hormonal methods of contraception only. (5.2)
  • Hypersensitivity Reactions: Acute hypersensitivity, including anaphylaxis, have been reported. Delayed hypersensitivity has been very rarely reported in association with leuprolide-containing therapy. Discontinue future leuprolide therapy at first signs or symptoms of a delayed hypersensitivity reaction, and treat patients according to current treatment guidelines. (5.3)
  • Cardiovascular and Metabolic Disorders: Assess and manage risk factors before starting LUPANETA PACK. (5.4)
  • Clinical Depression: Carefully observe women for depression and refer to a mental health professional, as appropriate. (5.7)
  • Visual Abnormalities: Discontinue norethindrone acetate in case of sudden loss of vision or onset of proptosis, diplopia, or migraine pending visual examination. Discontinue LUPANETA PACK if examination reveals papilledema or retinal vascular lesions. (5.8)

ADVERSE REACTIONS

Leuprolide acetate for depot suspension co-administered with norethindrone acetate: Most common related adverse reactions (>10%) were hot flashes/sweats, headache/migraine, nausea/vomiting, pain, depression/emotional lability, asthenia, constipation/diarrhea, vaginitis, insomnia/sleep disorder, breast changes/pain/tenderness, weight gain, dizziness/vertigo. (6.1

FULL PRESCRIBING INFORMATION

1 INDICATIONS AND USAGE

LUPANETA PACK is indicated for initial management of the painful symptoms of endometriosis and for management of recurrence of symptoms.

Limitations of Use 

The total duration of therapy with LUPANETA PACK should not exceed 12 months due to concerns about the adverse impact on bone mineral density [see Dosage and Administration (2.1) and Warnings and Precautions (5.1)].

2 DOSAGE AND ADMINISTRATION

2.1 Important Dosage and Administration Information

LUPANETA PACK is a co-packaged product containing leuprolide acetate for depot suspension 11.25 mg for intramuscular use and norethindrone acetate 5 mg tablets for oral use.

  • Do not administer leuprolide acetate for depot suspension 11.25 mg in the LUPANETA PACK alone if the patient is not taking norethindrone acetate.  
  • Do not administer leuprolide acetate for depot suspension 11.25 mg more frequently than every 3 months.
  • Do not administer a fractional dose of leuprolide acetate for depot suspension 11.25 mg.
  • Do not substitute the leuprolide acetate for depot suspension 11.25 mg (3 months of therapy) component for the leuprolide acetate for depot suspension 3.75 mg (one month of therapy) component of the LUPANETA PACK; they are not equivalent due to the different release characteristics.

2.2 Recommended Dosage and Administration

The recommended initial and retreatment dosage regimens for LUPANETA PACK for the management of  women with endometriosis are outlined in Table 1.

Assess bone mineral density (BMD) prior to retreatment with LUPANETA PACK [see Warnings and Precautions (5.1)]. 

Total treatment duration with LUPANETA PACK should not exceed 12 months due to concerns about the adverse impact on bone mineral density.

2.3 Reconstitution and Administration Instructions for Leuprolide Acetate Injection

  • Reconstitute and administer the lyophilized microspheres as a single IM injection as directed below. Visually inspect the drug product for particulate matter and discoloration prior to administration, whenever solution and container permit.
  • Inject the leuprolide acetate for depot suspension 11.25 mg immediately or discard if not used within two hours as the suspension does not contain a preservative. 

1. Visually inspect the leuprolide acetate for depot suspension powder. 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.

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).

      Figure 1:

Figure 1

      Figure 2:

Figure 2

3. Hold the syringe UPRIGHT. Release the diluent by SLOWLY PUSHING the plunger for 6 to 8 seconds until the first middle stopper is at the blue line in the middle of the barrel (see Figure 3).

      Figure 3:

Figure 3

4. Keep the syringe upright. Mix the microsphere 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 (see Figure 4).

      Figure 4:

Figure 4

5. Keep 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 IM injection by inserting the needle at a 90 degree angle into the gluteal area, anterior thigh, or deltoid (see Figure 5). Injection sites should be alternated (see Figure 5).

      Figure 5:

Figure 5

Note: If a blood vessel is accidentally penetrated, aspirated blood will be visible just below the luer lock (see Figure 6) and can be seen through the transparent LuproLoc safety device. If blood is present, remove the needle immediately. Do not inject the medication.

      Figure 6:

Figure 6

8. Inject the entire contents of the syringe intramuscularly.  

9. Withdraw the needle. Once the syringe has been withdrawn, immediately activate 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 over the needle is fully extended and a click is heard or felt (see Figure 7).

      Figure 7:

Figure 7

10. Dispose of the syringe according to local regulations/procedures. 

3 DOSAGE FORMS AND STRENGTHS

LUPANETA PACK 3-month co-packaged kit contains two separate components:

  • For Injection: Leuprolide acetate for depot suspension 11.25 mg as a white lyophilized microsphere powder for reconstitution in a single-dose prefilled dual chamber syringe, with one chamber containing the lyophilized powder and the other chamber containing the clear diluent. 
  • Tablets: Norethindrone acetate 5 mg tablets as white to off-white oval, flat-faced beveled edged, uncoated, debossed with ‘G’ with a break line on one side and ‘304’ on the other side

4 CONTRAINDICATIONS

LUPANETA PACK is contraindicated in women with the following:

  • Hypersensitivity to gonadotropin-releasing hormone (GnRH), GnRH agonist analogs, any of the excipients in leuprolide acetate for depot suspension, or norethindrone acetate
  • Undiagnosed abnormal uterine bleeding
  • Pregnancy [see Warnings and Precautions (5.2) and Use in Specific Populations (8.1)]
  • Known, suspected or history of breast cancer or other hormone-sensitive cancer
  • Current or history of thrombotic or thromboembolic disorder
  • Liver tumors or liver disease

5 WARNINGS AND PRECAUTIONS

5.1 Loss of Bone Mineral Density

Leuprolide acetate for depot suspension induces a hypoestrogenic state that results in loss of bone mineral density (BMD), some of which may not be reversible after stopping treatment. In women with major risk factors for decreased BMD such as chronic alcohol use (> 3 units per day), tobacco use, strong family history of osteoporosis, or chronic use of drugs that can decrease BMD, such as anticonvulsants or corticosteroids, use of LUPANETA PACK may pose an additional risk. Carefully weigh the risks and benefits of LUPANETA PACK use in these populations.

Total treatment duration with LUPANETA PACK should not exceed 12 months. The duration of LUPANETA PACK treatment is limited by the risk of loss of bone mineral density [see Dosage and Administration (2.1)].

When using LUPANETA PACK for the management of endometriosis, the norethindrone acetate component of the LUPANETA PACK reduces the BMD loss that occurs with leuprolide acetate use alone [see Clinical Studies (14)].  Do not retreat with leuprolide acetate for depot suspension alone. Assess BMD after 6 months of treatment before retreatment.

5.2 Embryo-Fetal Toxicity

Based on animal reproduction studies and the drug’s mechanism of action, leuprolide acetate for depot suspension may cause fetal harm if administered to a pregnant woman and is contraindicated in pregnant women. Exclude pregnancy prior to initiating treatment with LUPANETA PACK if clinically indicated. Discontinue LUPANETA PACK if the woman becomes pregnant during treatment and inform the woman of potential risk to the fetus [see Contraindications (4) and Use in Specific Populations (8.1)]. Advise women to notify their healthcare provider if they believe they may be pregnant.

When used at the recommended dose and dosing interval, leuprolide acetate for depot suspension usually inhibits ovulation and stops menstruation. Contraception, however, is not ensured by taking leuprolide acetate for depot suspension. If contraception is indicated, advise women to use nonhormonal methods of contraception while on treatment with LUPANETA PACK. 

5.3 Hypersensitivity Reactions

Acute Hypersensivity

Acute hypersensitivity reactions, including anaphylaxis, have been reported with LUPANETA PACK use. LUPANETA PACK is contraindicated in women with a history of hypersensitivity to gonadotropin-releasing hormone (GnRH), GnRH agonist analogs, or norethindrone acetate [see Adverse Reactions (6.2)].

In clinical trials for LUPANETA PACK, adverse events of asthma were reported in women with pre-existing histories of asthma, sinusitis and environmental or drug allergies. Symptoms consistent with an anaphylactoid or asthmatic process have been reported postmarketing.

Delayed Hypersensitivity

Delayed hypersensitivity reactions including the severe cutaneous adverse reactions (SCAR) of Stevens-Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) have been very rarely reported post-marketing in association with leuprolide-containing therapy [see Adverse Reactions (6.2)]. Discontinue future leuprolide therapy at first signs or symptoms of a delayed hypersensitivity reaction, and treat patients according to current treatment guidelines.

5.4 Cardiovascular and Metabolic Disorders

Assess and manage risk factors for cardiovascular disease before starting LUPANETA PACK. Closely monitor women on norethindrone acetate who have risk factors for arterial vascular disease (e.g., hypertension, diabetes mellitus, tobacco use, hypercholesterolemia, and obesity) and/or venous thromboembolism (e.g., family history of VTE, obesity, and smoking) when using LUPANETA PACK [see Contraindications (4)].

5.5 Initial Flare of Symptoms

Following the first dose of leuprolide acetate component of LUPANETA PACK, sex steroids temporarily rise above baseline because of the physiologic effect of the drug. Therefore, an increase in symptoms may be observed during the initial days of therapy, but these should dissipate with continued therapy.

5.6 Convulsions

There have been postmarketing reports of convulsions in women taking GnRH agonists such as the leuprolide acetate component of LUPANETA PACK. These included women with and without concurrent medications and comorbid conditions.

5.7 Clinical Depression

Depression may occur or worsen during treatment with GnRH agonists including LUPANETA PACK [see Adverse Reactions (6.1)]. Carefully observe women for depression, especially those with a history of depression and consider whether the risks of continuing LUPANETA PACK outweigh the benefits. Women with new or worsening depression should be referred to a mental health professional, as appropriate.

5.8 Visual Abnormalities

Discontinue norethindrone acetate tablets in the LUPANETA PACK pending examination if there is a sudden partial or complete loss of vision or if there is sudden onset of proptosis, diplopia, or migraine. Discontinue LUPANETA PACK if examination reveals papilledema or retinal vascular lesions.

5.9 Fluid Retention

Because norethindrone acetate, a component of LUPANETA PACK, may cause some degree of fluid retention, carefully observe women with conditions that might be influenced by this effect, such as epilepsy, migraine, cardiac or renal dysfunctions.

6 ADVERSE REACTIONS

The following clinically significant adverse reactions are described elsewhere in the labeling:

  • Loss of Bone Mineral Density [see Warnings and Precautions (5.1)]
  • Hypersensitivity Reactions [see Warnings and Precautions (5.3)]
  • Initial Flare of Symptoms [see Warnings and Precautions (5.5)]
  • Convulsions [see Warnings and Precautions (5.6)]
  • Clinical Depression [see Warnings and Precautions (5.7)]

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

The safety of co-administering leuprolide acetate for depot suspension and norethindrone acetate was evaluated in two clinical studies in which a total of 242 women were treated for up to one year. Women were treated with monthly IM injections of leuprolide acetate 3.75 mg (13 injections) alone or monthly IM injections of leuprolide acetate 3.75 mg (13 injections) and norethindrone acetate 5 mg orally once daily. The population age range was 17-43 years old. The majority of women were Caucasian (87%).

In the first study, 106 women were randomized to one year of treatment with leuprolide acetate for depot suspension alone or with leuprolide acetate for depot suspension and norethindrone acetate. The second study was an open-label, single arm clinical study in 136 women who received one year of leuprolide acetate for depot suspension and norethindrone acetate; these women were followed for up to 12 months after completing treatment.

Adverse Reactions (>1%) Leading to Study Discontinuation:

In the controlled study, 18% of women treated monthly with leuprolide acetate for depot suspension 3.75 mg alone and 18% of women treated concomitantly monthly with leuprolide acetate for depot suspension 3.75 mg and norethindrone acetate 5 mg discontinued therapy due to adverse reactions. The most common adverse reactions leading to discontinuation were hot flashes (6%) and insomnia (4%) in the leuprolide acetate for depot suspension 3.75 mg alone group and hot flashes and emotional lability (4% each) in the leuprolide acetate for depot suspension 3.75 mg and norethindrone acetate 5 mg group.

In the open-label study, 13% of women treated monthly with leuprolide acetate for depot suspension 3.75 mg plus norethindrone acetate 5 mg discontinued therapy due to adverse reactions, most commonly depression (4%) and acne (2%).

Common Adverse Reactions:

Table 2 lists the adverse reactions observed in at least 5% of women in any treatment group, during the first 6 months of treatment in the two clinical studies. The most common adverse reactions observed in these studies were hot flashes and headaches.

Serious Adverse Reactions:

Urinary tract infection (1.9%), renal calculus (0.7%), depression (0.7%)

Changes in Laboratory Values during Treatment:

Liver Enzymes

In the two clinical trials of women with endometriosis, 2% (4 of 191) women receiving leuprolide acetate for depot suspension and norethindrone acetate for up to 12 months developed an elevated (at least twice the upper limit of normal) serum glutamic pyruvic transaminase (SGPT) and 1% (2 of 136) developed an elevated gamma glutamyl transferase (GGT). Among these six women with increased liver tests, the increases in five were observed beyond 6 months of treatment. None were associated with an elevated bilirubin concentration.

Lipids 

Percent changes from baseline for serum lipids and percentages of women with serum lipid values outside of the normal range in the two studies of leuprolide acetate for depot suspension 3.75 mg and norethindrone acetate 5 mg daily are summarized in Tables 4 and 5 below. The major impact of adding norethindrone acetate to treatment with leuprolide acetate for depot suspension was a decrease in serum HDL cholesterol and an increase in the LDL/HDL ratio.

6.2 Postmarketing Experience

The following adverse reactions have been identified during post-approval use of leuprolide acetate for depot suspension or norethindrone acetate. 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.

During postmarketing surveillance which includes other dosage forms and other populations, the following adverse reactions were reported:

  • Body as a whole: Hypersensitivity reactions including anaphylaxis, localized reactions including induration and abscess at the site of injection
  • Nervous/Psychiatric System: Mood swings, including depression; suicidal ideation and attempt; convulsion, peripheral neuropathy, paralysis 
  • Hepato-biliary system: Serious liver injury
  • Skin reactions: erythema multiforme, dermatitis bullous, dermatitis exfoliative, Stevens-Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN)
  • Injury, poisoning and procedural complications: Spinal fracture
  • Investigations: Decreased white blood count
  • Musculoskeletal and connective tissue system: Tenosynovitis-like symptoms
  • Vascular system: Hypotension, hypertension, deep vein thrombosis, pulmonary embolism, myocardial infarction, stroke, transient ischemic attack
  • Respiratory system: Symptoms consistent with an asthmatic process 
  • Multi-system disorders: Symptoms consistent with fibromyalgia (e.g., joint and muscle pain, headaches, sleep disorders, gastrointestinal distress, and shortness of breath), individually and collectively.

Pituitary apoplexy

During post-marketing surveillance, cases of pituitary apoplexy (a clinical syndrome secondary to infarction of the pituitary gland) have been reported after the administration of leuprolide acetate and other GnRH 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

Leuprolide Acetate for Depot Suspension

No drug-drug interaction studies have been conducted with leuprolide acetate for depot suspension 11.25 mg. However, 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. 

Norethindrone Acetate

No pharmacokinetic drug interaction studies investigating any drug-drug interactions with norethindrone acetate have been conducted. Drugs or herbal products that induce or inhibit certain enzymes, including CYP3A4, may decrease or increase the serum concentrations of norethindrone, respectively.

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Risk Summary

LUPANETA PACK is contraindicated in pregnancy [see Contraindications (4)]

Leuprolide acetate for depot suspension may cause fetal harm based on findings from animal studies and the drug’s mechanism of action [see Clinical Pharmacology (12.1)]. There are limited human data on the use of LUPANETA PACK in pregnant women. Based on animal reproduction studies, leuprolide acetate for depot suspension 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].

Data

Animal Data

When administered on day 6 of pregnancy at test dosages of 0.00024, 0.0024, and 0.024 mg/kg (1/300 to 1/3 of the human dose) to rabbits, leuprolide acetate produced a dose-related increase in major fetal abnormalities. 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.

8.2 Lactation

Risk Summary 

There are no data on the presence of leuprolide acetate for depot suspension in either animal or human milk, the effects on the breastfed infants, or the effects on milk production. Detectable amounts of progestins have been identified in the milk of mothers receiving them.

The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for LUPANETA PACK and any potential adverse effects on the breastfed infant from LUPANETA PACK or from the underlying maternal condition.

8.3 Females and Males of Reproductive Potential

Pregnancy Testing

Exclude pregnancy in women of reproductive potential prior to initiating LUPANETA PACK if clinically indicated [see Warnings and Precautions (5.2)].

Contraception

Females

Based on animal reproduction studies and the drug’s mechanism of action, the leuprolide acetate component of LUPANETA PACK may cause embryo-fetal harm when administered during pregnancy. LUPANETA PACK is not a contraceptive. If contraception is indicated, advise females of reproductive potential to use a non-hormonal method of contraception during treatment with LUPANETA PACK [see Warnings and Precautions (5.2)].

Infertility

Based on its pharmacodynamic effects of decreasing secretion of gonadal steroids, fertility is expected to be decreased while on treatment with LUPANETA PACK. 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 (12.1)].

There is no evidence that pregnancy rates are affected following discontinuation of LUPANETA PACK.

Animal studies (prepubertal and adult rats and monkeys) with leuprolide acetate and other GnRH analogs have shown functional recovery of fertility suppression.

8.4 Pediatric Use

Safety and effectiveness of LUPANETA PACK for management of endometriosis have been established in females of reproductive age. Efficacy is expected to be the same for postpubertal adolescents under the age of 18 as for users 18 years and older. The safety and effectiveness of LUPANETA PACK for these indications have not been established in premenarcheal pediatric patients.

8.5 Geriatric Use

LUPANETA PACK is not indicated in postmenopausal women and has not been studied in women over 65 years of age.

11 DESCRIPTION

LUPANETA PACK (leuprolide acetate for depot suspension; norethindrone acetate tablets) 3-month co-packaged kit contains one dual chamber syringe with leuprolide acetate for depot suspension 11.25 mg and norethindrone acetate tablets USP: 5 mg (bottle of 90 tablets).

Leuprolide Acetate for Depot Suspension

Leuprolide acetate is a synthetic nonapeptide analog of gonadotropin-releasing hormone [(GnRH) or luteinizing hormone releasing hormone (LH-RH)], a GnRH agonist. 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:

structural formula

Leuprolide acetate for depot suspension 11.25 mg is available in a prefilled dual-chamber syringe containing sterile lyophilized microsphere powder which, when mixed with diluent, become a suspension intended as an IM injection.

The front chamber of the leuprolide acetate for depot suspension 11.25 mg prefilled dual-chamber syringe contains leuprolide acetate for depot suspension (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 mg), polysorbate 80 (1.5 mg), water for injection, USP, and glacial acetic acid, USP to control pH.

During the manufacturing of leuprolide acetate for depot suspension, acetic acid is lost, leaving the peptide.

Norethindrone Acetate

Norethindrone acetate tablets USP - 5 mg oral tablets.

Norethindrone acetate USP, (17-hydroxy-19-nor-17α-pregn-4-en-20-yn-3-one acetate), a synthetic, orally active progestin, is the acetic acid ester of norethindrone. It is a white, or creamy white, crystalline powder.

Description: norethindrone chemical structure

Norethindrone acetate tablets USP, 5 mg contain the following inactive ingredients: colloidal silicon dioxide, lactose monohydrate, magnesium stearate, microcrystalline cellulose and talc.

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Leuprolide Acetate for Depot Suspension

Leuprolide acetate for depot suspension is a long-acting GnRH analog. A single injection of leuprolide acetate for depot suspension results in an initial elevation followed by a prolonged suppression of pituitary gonadotropins. Repeated dosing at quarterly intervals results in decreased secretion of gonadal steroids; consequently, tissues and functions that depend on gonadal steroids for their maintenance become quiescent. This effect is reversible on discontinuation of drug therapy.

Leuprolide acetate is not active when given orally.

Norethindrone Acetate 

Norethindrone acetate induces secretory changes in an estrogen-primed endometrium.

12.2 Pharmacodynamics

In a pharmacokinetic/pharmacodynamic study of leuprolide acetate for depot suspension 11.25 mg in healthy female subjects (N=20), the onset of estradiol suppression was observed for individual subjects between day 4 and week 4 after dosing. By the third week following the injection, the mean estradiol concentration (8 pg/mL) was in the menopausal range. Throughout the remainder of the dosing period, mean serum estradiol levels ranged from the menopausal to the early follicular range.

Serum estradiol was suppressed to ≤20 pg/mL in all subjects within four weeks and remained suppressed (≤40 pg/mL) in 80% of subjects until the end of the 12-week dosing interval, at which time two of these subjects had a value between 40 and 50 pg/mL. Four additional subjects had at least two consecutive elevations of estradiol (range 43-240 pg/mL) levels during the 12-week dosing interval, but there was no indication of luteal function for any of the subjects during this period.

Administration of leuprolide acetate for depot suspension 11.25 mg results in suppression of the pituitary-gonadal system. Normal function is usually restored within three months after treatment is discontinued. Therefore, diagnostic tests of pituitary gonadotropic and gonadal functions conducted during treatment and for up to three months after discontinuation of leuprolide acetate for depot suspension 11.25 mg may be affected.

In a pharmacokinetic/pharmacodynamic study of endometriosis patients, intramuscular leuprolide acetate for depot suspension 11.25 mg (n=19) every 12 weeks or intramuscular leuprolide acetate for depot suspension 3.75 mg (n=15) every 4 weeks was administered for 24 weeks. There was no statistically significant difference in changes of serum estradiol concentration from baseline between the 2 treatment groups.

12.3 Pharmacokinetics

Absorption

Leuprolide Acetate for Depot Suspension

Following a single injection of the 3-month formulation of leuprolide acetate for depot suspension 11.25 mg in female subjects, a mean plasma leuprolide concentration of 36.3 ng/mL was observed at 4 hours. Leuprolide appeared to be released at a constant rate following the onset of steady-state levels during the third week after dosing and mean levels then declined gradually to near the lower limit of detection by 12 weeks. The mean (± standard deviation) leuprolide concentration from 3 to 12 weeks was 0.23 ± 0.09 ng/mL. However, intact leuprolide and an inactive major metabolite could not be distinguished by the assay which was employed in the study. The initial burst, followed by the rapid decline to a steady-state level, was similar to the release pattern seen with the monthly formulation.

Norethindrone Acetate

Norethindrone acetate is deacetylated to norethindrone after oral administration, and the disposition of norethindrone acetate is indistinguishable from that of orally administered norethindrone. Norethindrone acetate is absorbed from norethindrone acetate tablets, with maximum plasma concentration of norethindrone generally occurring at about 2 hours post-dose (see Figure 8). The pharmacokinetic parameters of norethindrone following single oral administration of norethindrone acetate 5 mg under fasting conditions in 29 healthy female volunteers are summarized in Table 6.

Distribution

Leuprolide Acetate for Depot Suspension

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%.

Norethindrone Acetate

Norethindrone is 36% bound to sex hormone-binding globulin (SHBG) and 61% bound to albumin. Volume of distribution of norethindrone is about 4 L/kg.

Metabolism

Leuprolide Acetate for Depot Suspension

Leuprolide acetate is a peptide that is primarily degraded by peptidase. In healthy male volunteers, a 1 mg bolus of leuprolide administered intravenously revealed that 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.

Metabolite I (M-I), a smaller inactive peptide, 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.

Norethindrone Acetate

Norethindrone undergoes extensive biotransformation, primarily via reduction, followed by sulfate and glucuronide conjugation. Norethindrone is also subject to oxidative metabolism catalyzed by CYP3A4. The majority of metabolites in the circulation are sulfates, with glucuronides accounting for most of the urinary metabolites.

Excretion

Leuprolide Acetate for Depot Suspension

Following administration of leuprolide acetate for depot suspension 3.75 mg to 3 patients, less than 5% of the dose was recovered as parent and M-I metabolite in the urine.

Norethindrone Acetate

Plasma clearance value for norethindrone is approximately 0.4 L/hr/kg. Norethindrone is excreted in both urine and feces, primarily as metabolites. The mean terminal elimination half-life of norethindrone following a single dose administration of norethindrone acetate is approximately 9 hours.

Use in Specific Populations

Hepatic Impairment

The effect of hepatic disease on the disposition of norethindrone after norethindrone acetate administration has not been evaluated. However, norethindrone acetate is contraindicated in markedly impaired liver function or liver disease [see Contraindications (4)]

The pharmacokinetics of the leuprolide acetate for depot suspension in hepatically impaired patients has not been determined.

Renal Impairment

The effect of renal disease on the disposition of norethindrone after norethindrone acetate administration has not been evaluated. In pre-menopausal women with chronic renal failure undergoing peritoneal dialysis who received multiple doses of an oral contraceptive containing ethinyl estradiol and norethindrone, plasma norethindrone concentration was unchanged compared to concentrations in pre-menopausal women with normal renal function.

The pharmacokinetics of the leuprolide acetate for depot suspension in renally impaired patients has not been determined.

Race

The effect of race on the disposition of norethindrone after norethindrone acetate administration has not been evaluated.

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Leuprolide Acetate for Depot Suspension

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. 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.

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

14 CLINICAL STUDIES

Two clinical studies with treatment duration of 12 months were conducted to evaluate the efficacy of LUPANETA PACK in relieving symptoms of endometriosis and the effect on the loss of bone mineral density (BMD). A total of 242 women were treated with monthly administration of leuprolide acetate for depot suspension 3.75 mg (13 injections) and 191 of them received co-administered norethindrone acetate 5 mg orally once daily. The population age range was 17-43 years old. The majority of women were Caucasian (87%). All women in these studies received calcium supplementation with 1000 mg elemental calcium.

The first study was a controlled, randomized, and double-blind study that included 51 women treated monthly with leuprolide acetate for depot suspension 3.75 mg alone and 55 women treated monthly with leuprolide acetate for depot suspension 3.75 mg and norethindrone acetate 5 mg daily. Women in this trial were followed for up to 24 months after completing one year of treatment. The second study was an open-label, single-arm clinical study in 136 women treated with leuprolide acetate for depot suspension 3.75 mg and norethindrone acetate 5 mg daily for one year; these women had follow-up for up to 12 months after completing treatment. See Table 7.

In both clinical studies, the assessment of efficacy was based on the investigator’s or the women’s monthly assessment of five signs or symptoms of endometriosis (dysmenorrhea, pelvic pain, deep dyspareunia, pelvic tenderness and pelvic induration).

Table 7 below provides detailed efficacy data regarding relief of symptoms of endometriosis based on the two studies of coadministration of leuprolide acetate for depot suspension 3.75 mg and norethindrone acetate 5 mg daily.

Suppression of menses (menses was defined as three or more consecutive days of menstrual bleeding) was maintained throughout treatment in 84% and 73% of women receiving leuprolide acetate and norethindrone acetate, in the controlled study and open label study, respectively. The median time for menses resumption after treatment with leuprolide acetate and norethindrone acetate was 8 weeks.

Changes in Bone

Density

The effect of leuprolide acetate for depot suspension 3.75 mg and norethindrone acetate 5 mg on bone mineral density was evaluated by dual energy x-ray absorptiometry (DXA) scan in the two clinical trials. For the open-label study, success in mitigating BMD loss was defined as the lower bound of the 95% confidence interval around the change from baseline at one year of treatment not to exceed -2.2%. The bone mineral density data of the lumbar spine from these two studies are presented in Table 8.
