Gonal-f RFF

DRUG DESCRIPTION

Gonal-f RFF (follitropin alfa for injection) is a human follicle stimulating hormone (FSH) preparation of recombinant DNA origin, which consists of two non-covalently linked, non-identical glycoproteins designated as the ?- and ?-subunits. The ?- and ?-subunits have 92 and 111 amino acids, respectively, and their primary and tertiary structure are indistinguishable from those of human follicle stimulating hormone. Recombinant FSH production occurs in genetically modified Chinese Hamster Ovary (CHO) cells cultured in bioreactors. Purification by immunochromatography using an antibody specifically binding FSH results in a highly purified preparation with a consistent FSH isoform profile, and a high specific activity. The biological activity of follitropin alfa is determined by measuring the increase in ovary weight in female rats. The in vivo biological activity of follitropin alfa has been calibrated against the first International Standard for recombinant human follicle stimulating hormone established in 1995 by the Expert Committee on Biological Standards of the World Health Organization. Gonal-f RFF (follitropin alfa injection) contains no luteinizing hormone (LH) activity. Based on available data derived from physico-chemical tests and bioassays, follitropin alfa and follitropin beta, another recombinant follicle stimulating hormone product, are indistinguishable.

Gonal-f RFF (follitropin alfa injection) is a sterile, lyophilized powder intended for subcutaneous injection after reconstitution.

Each Gonal-f RFF single-dose vial is filled with 82 IU (6 g)follitropin alfa to deliver 75 IU (5.5 g) follitropin alfa and contains 30 mg sucrose, 1.11 mg dibasic sodium phosphate dihydrate, 0.45 mg monobasic sodium phosphate monohydrate, 0.1 mg methionine, and 0.05 mg polysorbate 20. Phosphoric acid and/or sodium hydroxide may be used prior to lyophilization for pH adjustment. Vials are reconstituted with Sterile Water for Injection, USP.

Under current storage conditions, Gonal-f RFF may contain up to 10% of oxidized follitropin alfa.

What is follicle stimulating hormone (Gonal-f RFF)?

Follicle stimulating hormone (FSH) is a naturally occurring hormone. FSH is important in the development of follicles (eggs) produced by the ovaries. FSH is also important in the development of sperm.

Follicle stimulating hormone is used to stimulate a follicle (egg) to develop and mature. It is used when a woman desires pregnancy and her ovaries can produce a follicle but hormonal stimulation is not sufficient to make the follicle mature. Follicle stimulating hormone is also used to stimulate the development of multiple eggs for in vitro fertilization. Follicle stimulating hormone can be used by men to increase the production of sperm.

Follicle stimulating hormone may also be used for purposes other than those listed in this medication guide.

What are the possible side effects of follicle stimulating hormone (Gonal-f RFF)?

Stop using follicle stimulating hormone and seek emergency medical attention or notify your doctor immediately if you experience any of the following serious side effects:

  • an allergic reaction (difficulty breathing; closing of the throat; swelling of the lips, tongue, or face; or hives);
  • pain, warmth, redness, numbness, or tingling in an arm or leg (which may indicate a blood clot);
  • confusion, severe dizziness, severe headache; or
  • difficulty breathing.

Approximately 5% of patients treated with follicle stimulating hormone develop ovarian hyperstimulation syndrome (OHSS), especially after the first cycle of therapy. Symptoms of OHSS include severe pelvic pain, swelling of the hands or legs, abdominal pain and swelling, shortness of breath, weight gain, low urine output, diarrhea, and nausea or vomiting. OHSS can be fatal. Notify your doctor immediately or seek emergency medical attention if you develop any of these symptoms.

Other side effects may also occur. Notify your doctor if you experience

  • ovarian enlargement presenting as abdominal or pelvic pain, tenderness, pressure, or swelling;
  • nausea, vomiting, diarrhea, or flatulence (gas);
  • fever or chills;
  • headache;
  • dizziness;
  • rapid pulse or heart rate;
  • muscle or joint weakness or aching;
  • breast tenderness;
  • spotting or menstrual changes;
  • pain, swelling, or irritation at the injection site; or
  • dry skin, a rash, or hair loss.

Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome. You may report side effects to FDA at 1-800-FDA-1088.

What is the most important information I should know about follicle stimulating hormone (Gonal-f RFF)?

Treatment with follicle stimulating hormone increases the likelihood of multiple births. Multiple births carry additional risk both for the mother and for fetuses. Discuss the risk of multiple births with your healthcare provider.
