Description
FYREMADEL (ganirelix acetate) injection is a synthetic decapeptide with high antagonistic activity against naturally occurring gonadotropin-releasing hormone (GnRH). Ganirelix acetate is derived from native GnRH with substitutions of amino acids at positions 1, 2, 3, 6, 8, and 10 to form the following molecular formula of the peptide: N-acetyl-3-(2-naphthyl)-D-alanyl-4-chloro-D-phenylalanyl-3-(3-pyridyl)-D-alanyl-L-seryl-L-tyrosyl-N 9 ,N 10 -diethyl-D-homoarginyl-L-leucyl-N 9 ,N 10 -diethyl-L-homoarginyl-L-prolyl-D-alanylamide acetate. The molecular weight for ganirelix acetate is 1570.4 as an anhydrous free base. The structural formula is as follows: Ganirelix Acetate FYREMADEL (ganirelix acetate) injection is supplied as a colorless, sterile, ready-to-use, aqueous solution intended for SUBCUTANEOUS administration only. Each single-dose, sterile, prefilled syringe contains 250 mcg/0.5 mL of ganirelix acetate, 0.1 mg glacial acetic acid, 23.5 mg mannitol, and water for injection adjusted to pH 5 with acetic acid and/or sodium hydroxide. Chemical Structure
Indications
Ganirelix acetate injection is indicated for the inhibition of premature LH surges in women undergoing controlled ovarian hyperstimulation.
Dosage
After initiating FSH therapy on Day 2 or 3 of the cycle, ganirelix acetate injection 250 mcg may be administered subcutaneously once daily during the mid to late portion of the follicular phase. By taking advantage of endogenous pituitary FSH secretion, the requirement for exogenously administered FSH may be reduced. Treatment with ganirelix acetate should be continued daily until the day of hCG administration. When a sufficient number of follicles of adequate size are present, as assessed by ultrasound, final maturation of follicles is induced by administering hCG. The administration of hCG should be withheld in cases where the ovaries are abnormally enlarged on the last day of FSH therapy to reduce the chance of developing OHSS (Ovarian Hyperstimulation Syndrome). Ganirelix acetate injection is supplied in a single-dose, sterile, prefilled syringe and is intended for SUBCUTANEOUS administration only. Air bubble(s) may be seen in the pre-filled syringe. This is expected, and removal of the air bubble(s) is not needed. Wash hands thoroughly with soap and water. The most convenient sites for SUBCUTANEOUS injection are in the abdomen around the navel or upper thigh. The injection site should be swabbed with a disinfectant to remove any surface bacteria. Clean about two inches around the point where the needle will be inserted and let the disinfectant dry for at least one minute before proceeding. With syringe held upward, remove needle cover. Pinch up a large area of skin between the finger and thumb. Vary the injection site a little with each injection. The needle should be inserted at the base of the pinched-up skin at an angle of 45 to 90° to the skin surface. When the needle is correctly positioned, it will be difficult to draw back on the plunger. If any blood is drawn into the syringe, the needle tip has penetrated a vein or artery. If this happens, withdraw the needle slightly and reposition the needle without removing it from the skin. Alternatively, remove the needle and use a new, sterile, prefilled syringe. Cover the injection site with a swab containing disinfectant and apply pressure; the site should stop bleeding within one or two minutes. Once the needle is correctly placed, depress the plunger slowly and steadily, so the solution is correctly injected and the skin is not damaged. Pull the syringe out quickly and apply pressure to the site with a swab containing disinfectant. Use the sterile, prefilled syringe only once. Discard the unused portion and dispose of it properly.
Contraindications
Ganirelix acetate injection is contraindicated under the following conditions: Known hypersensitivity to ganirelix acetate or to any of its components including dry natural rubber/latex (see HOW SUPPLIED ). Known hypersensitivity to GnRH or any other GnRH analog. Known or suspected pregnancy (see PRECAUTIONS ).
Precautions
Special care should be taken in women with signs and symptoms of active allergic conditions. Cases of hypersensitivity reactions (both generalized and local), including anaphylaxis (including anaphylactic shock), angioedema and urticaria have been reported with ganirelix acetate, as early as with the first dose, during postmarketing surveillance (see ADVERSE REACTIONS ). If a hypersensitivity reaction is suspected, ganirelix acetate should be discontinued and appropriate treatment administered. In the absence of clinical experience, ganirelix acetate treatment is not advised in women with severe allergic conditions. The needle shield of this product contains dry natural rubber/latex which comes into contact with this product and may cause allergic reactions (see CONTRAINDICATIONS and HOW SUPPLIED ). Prior to therapy with ganirelix acetate injection, patients should be informed of the duration of treatment and monitoring procedures that will be required. The risk of possible adverse reactions should be discussed (see ADVERSE REACTIONS ). Ganirelix acetate should not be prescribed if the patient is pregnant. A neutrophil count ≥ 8.3 ( × 10 9 /L) was noted in 11.9% (up to 16.8 × 10 9 /L) of all subjects treated within the adequate and well-controlled clinical trials. In addition, downward shifts within the ganirelix acetate injection group were observed for hematocrit and total bilirubin. The clinical significance of these findings was not determined. No formal drug-drug interaction studies have been performed. Long-term toxicity studies in animals have not been performed with ganirelix acetate injection to evaluate the carcinogenic potential of the drug. Ganirelix acetate did not induce a mutagenic response in the Ames test ( S. typhimurium and E. coli ) or produce chromosomal aberrations in in vitro assay using Chinese Hamster Ovary cells. Ganirelix acetate injection is contraindicated in pregnant women. When administered from Day 7 to near term to pregnant rats and rabbits at doses up to 10 and 30 mcg/day (approximately 0.4 to 3.2 times the human dose based on body surface area), ganirelix acetate increased the incidence of litter resorption. There was no increase in fetal abnormalities. No treatment-related changes in fertility, physical, or behavioral characteristics were observed in the offspring of female rats treated with ganirelix acetate during pregnancy and lactation. The effects on fetal resorption are logical consequences of the alteration in hormonal levels brought about by the antigonadotropic properties of this drug and could result in fetal loss in humans. Therefore, this drug should not be used in pregnant women (see CONTRAINDICATIONS ). Ganirelix acetate injection should not be used by lactating women. It is not known whether this drug is excreted in human milk. Clinical studies with ganirelix acetate injection did not include a sufficient number of subjects aged 65 and over.
Adverse reactions
The safety of ganirelix acetate injection was evaluated in two randomized, parallel-group, multicenter controlled clinical studies. Treatment duration for ganirelix acetate ranged from 1 to 14 days. Table IV represents adverse events (AEs) from first day of ganirelix acetate administration until confirmation of pregnancy by ultrasound at an incidence of ≥ 1% in ganirelix acetate-treated subjects without regard to causality.
Drug interactions
No formal drug-drug interaction studies have been performed.

Protect from light.
Clinical pharmacology
The pulsatile release of GnRH stimulates the synthesis and secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). The frequency of LH pulses in the mid and late follicular phase is approximately 1 pulse per hour. These pulses can be detected as transient rises in serum LH. At midcycle, a large increase in GnRH release results in an LH surge. The midcycle LH surge initiates several physiologic actions including: ovulation, resumption of meiosis in the oocyte, and luteinization. Luteinization results in a rise in serum progesterone with an accompanying decrease in estradiol levels. Ganirelix acetate acts by competitively blocking the GnRH receptors on the pituitary gonadotroph and subsequent transduction pathway. It induces a rapid, reversible suppression of gonadotropin secretion. The suppression of pituitary LH secretion by ganirelix acetate is more pronounced than that of FSH. An initial release of endogenous gonadotropins has not been detected with ganirelix acetate, which is consistent with an antagonist effect. Upon discontinuation of ganirelix acetate, pituitary LH and FSH levels are fully recovered within 48 hours. The pharmacokinetic parameters of single and multiple injections of ganirelix acetate injection in healthy adult females are summarized in Table I. Steady-state serum concentrations are reached after 3 days of treatment. The pharmacokinetics of ganirelix acetate are dose-proportional in the dose range of 125 mcg to 500 mcg.

The mean absolute bioavailability of ganirelix acetate following a single 250 mcg subcutaneous injection to healthy female volunteers is 91.1%. The mean (SD) volume of distribution of ganirelix acetate in healthy females following intravenous administration of a single 250 mcg dose is 43.7 (11.4) liters (L). In vitro protein binding to human plasma is 81.9%. Following single-dose intravenous administration of radiolabeled ganirelix acetate to healthy female volunteers, ganirelix acetate is the major compound present in the plasma (50 to 70% of total radioactivity in the plasma) up to 4 hours and urine (17.1 to 18.4% of administered dose) up to 24 hours. Ganirelix acetate is not found in the feces. The 1 to 4 peptide and 1 to 6 peptide of ganirelix acetate are the primary metabolites observed in the feces. On average, 97.2% of the total radiolabeled ganirelix acetate dose is recovered in the feces and urine (75.1% and 22.1%, respectively) over 288 h following intravenous single dose administration of 1 mg [ 14 C]-ganirelix acetate. Urinary excretion is virtually complete in 24 h, whereas fecal excretion starts to plateau 192 h after dosing. The pharmacokinetics of ganirelix acetate injection have not been determined in special populations such as geriatric, pediatric, renally impaired and hepatically impaired patients (see PRECAUTIONS ). Formal in vivo or in vitro drug-drug interaction studies have not been conducted (see PRECAUTIONS ). Since ganirelix acetate can suppress the secretion of pituitary gonadotropins, dose adjustments of exogenous gonadotropins may be necessary when used during controlled ovarian hyperstimulation (COH). The efficacy of ganirelix acetate injection was established in two adequate and well-controlled clinical studies which included women with normal endocrine and pelvic ultrasound parameters. The studies intended to exclude subjects with polycystic ovary syndrome (PCOS) and subjects with low or no ovarian reserve. One cycle of study medication was administered to each randomized subject. For both studies, the administration of exogenous recombinant FSH [Follistim ® All trademark names are the property of their respective owners. (follitropin beta for injection)] 150 IU daily was initiated on the morning of Day 2 or 3 of a natural menstrual cycle. Ganirelix acetate injection was administered on the morning of Day 7 or 8 (Day 6 of recombinant FSH administration). The dose of recombinant FSH administered was adjusted according to individual responses starting on the day of initiation of ganirelix acetate. Both recombinant FSH and ganirelix acetate were continued daily until at least three follicles were 17 mm or greater in diameter at which time hCG [Pregnyl ® (chorionic gonadotropin for injection, USP)] was administered. Following hCG administration, ganirelix acetate and recombinant FSH administration were discontinued. Oocyte retrieval, followed by in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI), was subsequently performed. In a multicenter, double-blind, randomized, dose-finding study, the safety and efficacy of ganirelix acetate injection were evaluated for the prevention of LH surges in women undergoing COH with recombinant FSH. Ganirelix acetate injection doses ranging from 62.5 mcg to 2,000 mcg and recombinant FSH were administered to 332 patients undergoing COH for IVF (see TABLE II ). Median serum LH on the day of hCG administration decreased with increasing doses of ganirelix acetate. Median serum E 2 (17β-estradiol) on the day of hCG administration was 1,475; 1,110; and 1,160 pg/mL for the 62.5 mcg, 125 mcg, and 250 mcg doses, respectively. Lower peak serum E 2 levels of 823, 703, and 441 pg/mL were seen at higher doses of ganirelix acetate 500 mcg, 1,000 mcg, and 2,000 mcg, respectively. The highest pregnancy and implantation rates were achieved with the 250 mcg dose of ganirelix acetate injection as summarized in Table II.

A multicenter, open-label, randomized study was conducted to assess the efficacy and safety of ganirelix acetate injection in women undergoing COH. Follicular phase treatment with ganirelix acetate 250 mcg was studied using a luteal phase GnRH agonist as a reference treatment. A total of 463 subjects were treated with ganirelix acetate by subcutaneous injection once daily starting on Day 6 of recombinant FSH treatment. Recombinant FSH was maintained at 150 IU for the first 5 days of ovarian stimulation and was then adjusted by the investigator on the sixth day of gonadotropin use according to individual responses.
