LUPRON DEPOT

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: LUPRON DEPOT 3.75 mg (leuprolide acetate for depot suspension for injection) is available in a prefilled dual-chamber syringe containing sterile lyophilized microspheres powder which, when mixed with diluent, become a suspension intended as an IM injection. The front chamber of LUPRON DEPOT 3.75 mg prefilled dual-chamber syringe contains leuprolide acetate for depot suspension (3.75 mg), purified gelatin (0.65 mg), DL-lactic and glycolic acids copolymer (33.1 mg) and D-mannitol (6.6 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. During the manufacture of LUPRON DEPOT 3.75 mg, acetic acid is lost, leaving the peptide. structural formula

( 1.1 ) In combination with a norethindrone acetate for initial management of the painful symptoms of endometriosis and for management of recurrence of symptoms. ( 1.1 ) Limitations of Use: The total duration of therapy with LUPRON DEPOT 3.75 mg plus add-back therapy should not exceed 12 months due to concerns about adverse impact on bone mineral density. ( 1.1 , 2.1 , 5.1 ) Uterine Leiomyomata (Fibroids) Concomitant use with iron therapy for preoperative hematologic improvement of women with anemia caused by fibroids for whom three months of hormonal suppression is deemed necessary. ( 1.2 ) Limitations of Use: LUPRON DEPOT 3.75 mg is not indicated for combination use with norethindrone acetate add-back therapy for the preoperative hematologic improvement of women with anemia caused by heavy menstrual bleeding due to fibroids. ( 1.2 ) 1.1 Endometriosis Monotherapy LUPRON DEPOT 3.75 mg is indicated for management of endometriosis, including pain relief and reduction of endometriotic lesions. In Combination with Norethindrone Acetate LUPRON DEPOT 3.75 mg in combination with norethindrone acetate is indicated for initial management of the painful symptoms of endometriosis and for management of recurrence of symptoms. Use of norethindrone acetate in combination with LUPRON DEPOT 3.75 mg is referred to as add-back therapy, and is intended to reduce the loss of bone mineral density (BMD) and reduce vasomotor symptoms associated with use of LUPRON DEPOT 3.75 mg. Limitations of Use : The total duration of therapy with LUPRON DEPOT 3.75 mg plus add-back therapy should not exceed 12 months due to concerns about adverse impact on bone mineral density [see Dosage and Administration ( 2.1 ) and Warnings and Precautions ( 5.1 ) ] . 1.2 Uterine Leiomyomata (Fibroids) LUPRON DEPOT 3.75 mg, used concomitantly with iron therapy, is indicated for the preoperative hematologic improvement of women with anemia caused by fibroids for whom three months of hormonal suppression is deemed necessary. Consider a one-month trial period on iron alone, as some women will respond to iron alone [see Clinical Studies ( 14.2 )] . LUPRON DEPOT 3.75 mg may be added if the response to iron alone is considered inadequate. Limitations of Use : LUPRON DEPOT 3.75 mg is not indicated for combination use with norethindrone acetate add-back therapy for the preoperative hematologic improvement of women with anemia caused by heavy menstrual bleeding due to fibroids [see Dosage and Administration ( 2.1 )] .

LUPRON DEPOT 3.75 mg for 1-month administration, given by a healthcare provider as a single intramuscular injection. LUPRON DEPOT 3.75 mg has different release characteristics than LUPRON 11.25 mg and is dosed differently. ( 2.1 ) Do not substitute LUPRON DEPOT 3.75 mg for LUPRON DEPOT 11.25 mg. Do not administer LUPRON DEPOT 3.75 mg more frequently than once a month. Do not give a fractional dose of the LUPRON DEPOT 11.25 mg 3-month formulation, as it is not equivalent to a single dose of the LUPRON DEPOT 3.75 mg. Do not give a triple dose of the LUPRON DEPOT 3.75 mg, as it is not equivalent to a single dose of the LUPRON DEPOT 11.25 mg 3- month formulation. Reconstitute LUPRON DEPOT 3.75 mg prior to use. ( 2.2 ) Endometriosis: LUPRON DEPOT 3.75 mg administered as a single intramuscular (IM) injection once every month for up to six injections (6 months of therapy). LUPRON DEPOT may be administered alone or in combination with daily 5 mg tablet of norethindrone acetate (add-back).

Fibroids The recommended dosage of LUPRON DEPOT 3.75 mg is one IM injection every month for up to three months. 2.2 Reconstitution and Administration for Injection of LUPRON DEPOT Reconstitute and administer the lyophilized microsphere 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 LUPRON DEPOT 3.75 mg suspension immediately or discard if not used within two hours as the suspension does not contain a preservative. 1. Visually inspect the LUPRON DEPOT 3.75 mg 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 A and Figure B ). Figure A: Figure B: 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 C ). Figure C: 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 D ). Figure D: 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. The syringe is now 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. Injection sites should be alternated (see Figure E ). Figure E: Note : If a blood vessel is accidentally penetrated, aspirated blood will be visible just below the luer lock (see Figure F ) and can be seen through the transparent LuproLoc ® safety device. If blood is present, remove the needle immediately. Do not inject the medication. Figure F: 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 G ). Figure G: 10. Dispose of the syringe according to local regulations/procedures.

LUPRON DEPOT 3.75 mg (Monotherapy) The safety of LUPRON DEPOT 3.75 mg for the endometriosis and fibroids indications was established based on adequate and well-controlled adult studies. The safety of LUPRON DEPOT 3.75 mg was evaluated in six clinical studies in which a total of 332 women were treated for up to six months. Women were treated with monthly IM injections of LUPRON DEPOT 3.75 mg. The population age range was 18 to 53 years old. Adverse Reactions (>1%) Leading to Study Discontinuation In the six studies 1.8% of women treated with LUPRON DEPOT 3.75 mg discontinued prematurely due to hot flashes. Common Adverse Reactions The safety of LUPRON DEPOT 3.75 mg was evaluated in controlled clinical trials in 166 women with endometriosis and 166 women with uterine fibroids. Adverse reactions reported in ≥ 5% of women in either of these populations are noted in Tables 2 and 3 , below. Table 2.

In one controlled clinical trial utilizing the monthly formulation of LUPRON DEPOT 3.75 mg and LUPRON DEPOT 7.5 mg in women diagnosed with uterine fibroids received one injection every 4 weeks for a duration of 12 weeks. Adverse reactions of galactorrhea, pyelonephritis, and urinary incontinence were reported in the 7.5 mg dose group but not in the 3.75 mg dose group. Generally, a higher incidence of hypoestrogenic effects was observed at the higher dose. LUPRON DEPOT 3.75 mg in combination with Norethindrone Acetate 5 mg The safety of co-administering LUPRON DEPOT 3.75 mg and norethindrone acetate was evaluated in two clinical studies in which a total of 242 women with endometriosis were treated for up to one year. Women were treated with monthly IM injections of LUPRON DEPOT 3.75 mg (13 injections) alone or monthly IM injections of LUPRON DEPOT 3.75 mg (13 injections) plus norethindrone acetate 5 mg daily. The population age range was 17 to 43 years old. The majority of women were Caucasian (87%). In one study, 106 women were randomized to one year of treatment with LUPRON DEPOT 3.75 mg alone or with LUPRON DEPOT 3.75 mg and norethindrone acetate. The other study was an open-label, single arm clinical study in 136 women on one year of treatment with LUPRON DEPOT 3.75 mg plus norethindrone acetate, with follow-up 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 LUPRON DEPOT 3.75 mg and 18% of women treated monthly with LUPRON DEPOT 3.75 mg plus norethindrone acetate discontinued therapy due to adverse reactions, most commonly hot flashes (6%) and insomnia (4%) in the LUPRON DEPOT 3.75 mg alone group and hot flashes and emotional lability (4% each) in the LUPRON DEPOT 3.75 mg plus norethindrone group. In the open-label study, 13% of women treated monthly with LUPRON DEPOT 3.75 mg plus norethindrone acetate discontinued therapy due to adverse reactions, most commonly depression (4%) and acne (2%). Common Adverse Reactions Table 4 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 add-back clinical studies, in which women were treated with monthly LUPRON DEPOT 3.75 mg with or without norethindrone acetate 5 mg daily co-treatment. The most frequently-occurring adverse reactions observed in these studies were hot flashes and headaches. Table 4.

Serious Adverse Reactions Urinary tract infection (1.9%), renal calculus (0.7%), depression (0.7%) Changes in Laboratory Values during Treatment Liver Enzymes Three percent of women with uterine fibroids treated with LUPRON DEPOT 3.75 mg, manifested post-treatment transaminase values that were at least twice the baseline value and above the upper limit of the normal range. In the two clinical trials of women with endometriosis, 2% (4 of 191) women receiving leuprolide acetate plus norethindrone acetate for up to 12 months developed an elevated (at least twice the upper limit of normal) SGPT and 1% (2 of 136) developed an elevated 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 Triglycerides were increased above the upper limit of normal in 12% of the women with endometriosis who received LUPRON DEPOT 3.75 mg. Of those women with endometriosis and women with uterine fibroid whose pretreatment cholesterol values were in the normal range, mean change following therapy was +16 mg/dL to +17 mg/dL in women with endometriosis and +11 mg/dL to +29 mg/dL in women with uterine fibroids. In the women with endometriosis, increases from the pretreatment values were statistically significant (p<0.03). There was essentially no increase in the LDL/HDL ratio in women from either population receiving LUPRON DEPOT 3.75 mg. 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 LUPRON DEPOT 3.75 mg and norethindrone acetate are summarized in Table 6 and Table 7 below. The major impact of adding norethindrone acetate to treatment with LUPRON DEPOT 3.75 mg was a decrease in serum HDL cholesterol and an increase in the LDL/HDL ratio. Table 6.

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: Skin and Subcutaneous Tissue : rash, urticaria, photosensitivity, erythema multiforme, bullous dermatitis, dermatitis exfoliative, drug reaction with eosinophilia and systemic symptoms (DRESS), Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN), and acute generalized exanthematous pustulosis (AGEP) Body as a whole: Hypersensitivity reactions including anaphylaxis Nervous/Psychiatric System: Mood swings, including depression; suicidal ideation and attempt; convulsion, peripheral neuropathy, paralysis Hepato-biliary system: Serious liver injury General disorders and administration site conditions : Injection site reactions including induration, abscess, and necrosis 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 postmarketing 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.
