WARNINGS 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 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 (24) Ovarian Hyperstimulation Syndrome 2.4 (19) Vaginal Bleeding 1.8 (14) Injection Site Reaction 1.1 (9) Nausea 1.1 (9) Abdominal Pain (gastrointestinal) 1 (8) During postmarketing surveillance, rare cases of hypersensitivity reactions, including anaphylactoid reactions, have been reported, as early as with the first dose (see PRECAUTIONS ). Congenital Anomalies Ongoing clinical follow-up studies of 283 newborns of women administered ganirelix acetate injection were reviewed. There were three neonates with major congenital anomalies and 18 neonates with minor congenital anomalies. The major congenital anomalies were: hydrocephalus/meningocele, omphalocele, and Beckwith-Wiedemann Syndrome. The minor congenital anomalies were: nevus, skin tags, sacral sinus, hemangioma, torticollis/asymmetric skull, talipes, supernumerary digit finger, hip subluxation, torticollis/high palate, occiput/abnormal hand crease, hernia umbilicalis, hernia inguinalis, hydrocele, undescended testis, and hydronephrosis. The causal relationship between these congenital anomalies and ganirelix acetate is unknown. Multiple factors, genetic and others (including, but not limited to ICSI, IVF, gonadotropins, progesterone) may confound ART (Assisted Reproductive Technology) procedures.
