Indications and Usage
openFDA Drug LabelingINDICATIONS AND USAGE Ganirelix Acetate Injection is indicated for the inhibition of premature LH surges in women undergoing controlled ovarian hyperstimulation.
Dosage and Administration
openFDA Drug LabelingDOSAGE AND ADMINISTRATION 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). Directions for Using Ganirelix Acetate Injection 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 45–90° 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
openFDA Drug LabelingCONTRAINDICATIONS Ganirelix Acetate Injection is contraindicated under the following conditions: Known hypersensitivity to Ganirelix Acetate or to any of its components. Known hypersensitivity to GnRH or any other GnRH analog. Known or suspected pregnancy (see PRECAUTIONS ).
Warnings
openFDA Drug LabelingWARNINGS Ganirelix Acetate Injection should be prescribed by physicians who are experienced in infertility treatment. Before starting treatment with Ganirelix Acetate, pregnancy must be excluded. Safe use of Ganirelix Acetate during pregnancy has not been established (see CONTRAINDICATIONS and PRECAUTIONS ).
Adverse Reactions
openFDA Drug LabelingADVERSE 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. TABLE IV: Incidence of common adverse events (Incidence ≥ 1% in Ganirelix Acetate-treated subjects). Completed controlled clinical studies (All-subjects-treated group). Adverse Events Occurring in ≥ 1% Ganirelix Acetate N=794 % (n) Abdominal Pain (gynecological) 4.8 (38) Death Fetal 3.7 (29) Headache 3.0 (24) Ovarian Hyper stimulation Syndrome 2.4 (19) Vaginal Bleeding 1.8 (14) Injection Site Reaction 1.1 (9) Nausea 1.1 (9) Abdominal Pain (gastrointestinal) 1.0 (8) During post-marketing surveillance, rare cases of hypersensitivity reactions, including anaphylaxis (including anaphylactic shock), angioedema and urticaria have been reported with Ganirelix Acetate, as early as with the first dose (see PRECAUTIONS ). Congenital Anomalies An observational study in more than 1000 newborns compared the incidence of congenital anomalies in newborns of women administered Ganirelix Acetate to historical controls of a GnRH agonist. This study demonstrated that the incidence of congenital anomalies in children born after COH treatment in women using Ganirelix Acetate was comparable with that reported alter a COH treatment cycle using a GnRH agonist. The incidence of congenital malformations alter some Assisted Reproductive Technologies (ART) [specifically in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI)] may be slightly higher than after spontaneous conception. This slightly higher incidence is thought to be related to differences in parental characteristics (e.g., maternal age, maternal and paternal genetic background, sperm characteristics) and to the higher incidence of multi-fetal gestations alter IVF or ICSI. The causal relationship between these congenital anomalies and Ganirelix Acetate Injection is unknown.

Drug Interactions

Use in Specific Populations
openFDA Drug LabelingSpecial Populations 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 ). Drug-Drug Interactions 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).
Description
openFDA Drug LabelingDESCRIPTION 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.
