Menotropins

Description

11 DESCRIPTION MENOPUR is a preparation of gonadotropins (FSH and LH activity), extracted from the urine of postmenopausal women, which has undergone additional steps for purification. MENOPUR is a sterile, lyophilized powder intended for subcutaneous (SC) injection after reconstitution with sterile 0.9% Sodium Chloride Injection, USP. Each vial of MENOPUR contains 75 International Units of follicle-stimulating hormone (FSH) activity and 75 International Units of luteinizing hormone (LH) activity, plus 21 mg lactose monohydrate and 0.005 mg Polysorbate 20 and Sodium Phosphate Buffer (Sodium Phosphate Dibasic, Heptahydrate and Phosphoric Acid). The biological activity of MENOPUR is determined using the bioassays for FSH (ovarian weight gain assay in female rats) and LH (seminal vesicle weight gain assay in male rats), modified to increase the accuracy and reproducibility of these assays. The FSH and LH activity assays are standardized using the Fourth International Standard for Urinary FSH and Urinary LH, November 2000, by the Expert Committee on Biological Standardization of the World Health Organization (WHO ECBS). Both FSH and LH are glycoproteins that are acidic and water-soluble. Human Chorionic Gonadotropin (hCG) is detected in MENOPUR. MENOPUR has been mixed in vitro with BRAVELLE with no evidence of aggregation. Therapeutic class: Infertility

What Is Menotropins Used For?

1 INDICATIONS AND USAGE MENOPUR ® (menotropins for injection) is a gonadotropin indicated for: Development of multiple follicles and pregnancy in ovulatory women as part of an Assisted Reproductive Technology (ART) cycle ( 1 ) Development of Multiple Follicles and Pregnancy in Ovulatory Women as Part of an Assisted Reproductive Technology (ART) Cycle Prior to initiation of treatment with MENOPUR ® (menotropins for injection): Perform a complete gynecologic and endocrinologic evaluation, and diagnose the cause of infertility Exclude the possibility of pregnancy Evaluate the fertility status of the male partner Exclude a diagnosis of primary ovarian failure

Dosage and Administration

2 DOSAGE AND ADMINISTRATION Initial starting dose of the first cycle - 225 International Units per day, administered subcutaneously ( 2.2 ) Dosage adjustments after 5 days and by no more than 150 International Units at each adjustment ( 2.2 ) Do not administer doses greater than 450 International Units per day ( 2.2 ) MENOPUR may be administered together with BRAVELLE ® (urofollitropin for injection, purified). Only the total starting dose of 225 International Units (150 International Units of MENOPUR and 75 International Units of BRAVELLE or 75 International Units of MENOPUR and 150 International Units of BRAVELLE) was studied in a clinical trial. ( 2.2 ) 2.1 General Dosing Information Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Administer MENOPUR subcutaneously in the abdomen as described in Instructions for Use. MENOPUR may be administered together with BRAVELLE ® (urofollitropin for injection, purified). 2.2 Recommended Dosing for Assisted Reproductive Technology The recommended dosing scheme for patients undergoing IVF follows a stepwise approach and is individualized for each woman. The recommended initial dose of MENOPUR for women who have received a GnRH agonist for pituitary suppression is 225 International Units. MENOPUR may be administered together with BRAVELLE and the total initial dose when the products are combined should not exceed 225 International Units (150 International Units of MENOPUR and 75 International Units of BRAVELLE or 75 International Units of MENOPUR and 150 International Units of BRAVELLE). Beginning on cycle day 2 or 3, a starting dose of 225 International Units of MENOPUR is administered subcutaneously daily. Adjust the dose after 5 days based on the woman's ovarian response, as determined by ultrasound evaluation of follicular growth and serum estradiol levels. Do not make additional dosage adjustments more frequently than every 2 days or by more than 150 International Units at each adjustment. Continue treatment until adequate follicular development is evident, and then administer hCG. Withhold the administration of hCG in cases where the ovarian monitoring suggests an increased risk of OHSS on the last day of MENOPUR therapy [ see Warnings and Precautions (5.1 , 5.2 , 5.10) ]. Do not administer daily doses of MENOPUR or MENOPUR in combination with BRAVELLE that exceed 450 International Units . Therapy should not exceed 20 days.

Side Effects (Adverse Reactions)

6 ADVERSE REACTIONS The following serious adverse reactions are discussed elsewhere in the labeling: Abnormal Ovarian Enlargement [see Warnings and Precautions (5.1) ] Ovarian Hyperstimulation Syndrome [see Warnings and Precautions (5.2) ] Atelectasis, acute respiratory distress syndrome and exacerbation of asthma [see Warnings and Precautions (5.3) ] Thromboembolic events [see Warnings and Precautions (5.3) ] Ovarian Torsion [see Warnings and Precautions (5.4) ] Multi-fetal Gestation and Birth [see Warnings and Precautions (5.5) ] Congenital Malformations [see Warnings and Precautions (5.6) ] Ectopic Pregnancy [see Warnings and Precautions (5.7) ] Spontaneous Abortion [see Warnings and Precautions (5.8) ] Ovarian Neoplasms [see Warnings and Precautions (5.9) ] The most common adverse reactions (≥2%) in ART include: abdominal cramps; abdomen enlarged; abdominal pain; headache; injection site pain and reaction; injection site inflammation; OHSS ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Ferring Pharmaceuticals Inc. at 1-888-FERRING (1-888-337-7464) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trial Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trial of another drug and may not reflect the rates observed in practice. In two single cycle, open label, multinational, multicenter, comparative trials, a total of 434 normal ovulatory infertile women were randomized and received subcutaneously administered MENOPUR as part of an in vitro fertilization (IVF) cycle (both trials) or intracytoplasmic sperm injection (ICSI) cycle (one of the two trials). All women received pituitary down-regulation with gonadotropin releasing hormone (GnRH) agonist before stimulation. Adverse Reactions occurring at an incidence of ≥ 2% in women receiving MENOPUR are shown in Table 1. Table 1: MENOPUR Administered Subcutaneously in Women Undergoing IVF and ICSI. Adverse Reactions with Incidence of 2% or Greater Occurring on or After GnRH Administration. Body System/Preferred Term IVF n=434 N % Body as a whole Abdominal cramps 13 3.0 Abdomen enlarged 10 2.3 Abdominal pain 29 6.7 Headache 27 6.2 Injection site pain + reaction 17 3.9 Injection site inflammation 10 2.3 Urogenital Ovarian Hyperstimulation Syndrome (OHSS) 27 6.2 In addition, thrombophlebitis was reported in less than 1% of subjects. In an open label, US, multicenter, comparative IVF and ICSI trial, MENOPUR and BRAVELLE were administered in the same syringe to 60 normal ovulatory infertile women. OHSS, post retrieval cramping and nausea and spontaneous abortion were the most common adverse reactions occurring at an incidence of ≥ 5% in women receiving the combination of MENOPUR and BRAVELLE. In another open label, US multicenter, comparative trial for ovulation induction in anovulatory or oligovulatory infertile women, 76 subjects received subcutaneous or intramuscular injections of MENOPUR. The most common adverse reactions occurring at an incidence of ≥ 5% in women receiving MENOPUR were: headache; OHSS; injection site reaction, abdominal cramps, fullness and pain; and nausea. 6.2 Postmarketing Experience The following adverse reactions have been reported during postmarketing use of gonadotropins. Because these reactions were reported voluntarily from a population of uncertain size, the frequency or a causal relationship to MENOPUR cannot be reliably determined. Gastrointestinal disorders: abdominal pain, abdominal pain lower, abdominal distension, nausea, vomiting, abdominal discomfort General disorders and administration site conditions: injection site reactions (most frequently reported injection site reaction was injection site pain), fatigue Nervous system disorders: headache, dizziness Reproductive system disorders: OHSS [see Warnings and Precautions (5.2) ] , pelvic pain, ovarian cyst, breast complaints...
