FOLLISTIM AQ Cartridge should be used only by physicians who are experienced in infertility treatment. FOLLISTIM AQ Cartridge contains a potent gonadotropic substance capable of causing Ovarian Hyperstimulation Syndrome (OHSS) [see Warnings and Precautions (5.2) ] with or without pulmonary or vascular complications [see Warnings and Precautions (5.3) ] and multiple births [see Warnings and Precautions (5.5) ] . Gonadotropin therapy requires the availability of appropriate monitoring facilities [see Warnings and Precautions (5.10) ] . Careful attention should be given to the diagnosis of infertility and in the selection of candidates for FOLLISTIM AQ Cartridge therapy [see Indications and Usage (1.1 , 1.2 , 1.3) and Dosage and Administration (2.2 , 2.3 , 2.4) ] . Switching to FOLLISTIM AQ Cartridge from other brands (manufacturer), types (recombinant, urinary), and/or methods of administration (FOLLISTIM Pen, conventional syringe) may necessitate an adjustment of the dose [see Dosage and Administration (2) ] . Treatment with FOLLISTIM AQ may result in: Abnormal Ovarian Enlargement ( 5.1 ) Ovarian Hyperstimulation Syndrome (OHSS) ( 5.2 ) Pulmonary and Vascular Complications ( 5.3 ) Ovarian Torsion ( 5.4 ) Multi-fetal Gestation and Birth ( 5.5 ) Congenital Anomalies ( 5.6 ) Ectopic Pregnancy ( 5.7 ) Spontaneous Abortion ( 5.8 ) Ovarian Neoplasms ( 5.9 )

5.1 Abnormal Ovarian Enlargement In order to minimize the hazards associated with abnormal ovarian enlargement that may occur with FOLLISTIM AQ therapy, treatment should be individualized and the lowest effective dose should be used [ see Dosage and Administration (2.2 , 2.3) ] . Use of ultrasound monitoring of ovarian response and/or measurement of serum estradiol levels is important to minimize the risk of overstimulation [see Warnings and Precautions (5.8) ] . If the ovaries are abnormally enlarged on the last day of FOLLISTIM AQ therapy, hCG should not be administered in order to reduce the chances of developing Ovarian Hyperstimulation Syndrome (OHSS). Intercourse should be prohibited in patients with significant ovarian enlargement after ovulation because of the danger of hemoperitoneum resulting from ruptured ovarian cysts [see Warnings and Precautions (5.3) ] .

5.2 Ovarian Hyperstimulation Syndrome (OHSS) OHSS is a medical entity distinct from uncomplicated ovarian enlargement and may progress rapidly to become a serious medical condition. OHSS is characterized by a dramatic increase in vascular permeability, which can result in a rapid accumulation of fluid in the peritoneal cavity, thorax, and potentially, the pericardium. The early warning signs of OHSS developing are severe pelvic pain, nausea, vomiting, and weight gain. Abdominal pain, abdominal distension, gastrointestinal symptoms including nausea, vomiting and diarrhea, severe ovarian enlargement, weight gain, dyspnea, and oliguria have been reported with OHSS. Clinical evaluation may reveal hypovolemia, hemoconcentration, electrolyte imbalances, ascites, hemoperitoneum, pleural effusions, hydrothorax, acute pulmonary distress, and thromboembolic reactions [see Warnings and Precautions (5.3) ] . Transient liver function test abnormalities suggestive of hepatic dysfunction with or without morphologic changes on liver biopsy have also been reported in association with OHSS. OHSS occurs after gonadotropin treatment has been discontinued, and it can develop rapidly, reaching its maximum about seven to ten days following treatment. Usually, OHSS resolves spontaneously with the onset of menses. If there is a risk for OHSS evident prior to hCG administration [see Warnings and Precautions (5.1) ] , the hCG must be withheld. Cases of OHSS are more common, more severe, and more protracted if pregnancy occurs; therefore, women should be assessed for the development of OHSS for at least two weeks after hCG administration. If serious OHSS occurs, gonadotropins, including hCG, should be stopped and consideration should be given as to whether the patient needs to be hospitalized. Treatment is primarily symptomatic and overall should consist of bed rest, fluid and electrolyte management, and analgesics (if needed). Because the use of diuretics can accentuate the diminished intravascular volume, diuretics should be avoided except in the late phase of resolution as described below. The management of OHSS may be divided into three phases as follows: Acute Phase: Management should be directed at preventing hemoconcentration due to loss of intravascular volume to the third space and minimizing the risk of thromboembolic phenomena and kidney damage. Fluid intake and output, weight, hematocrit, serum and urinary electrolytes, urine specific gravity, BUN and creatinine, total proteins with albumin: globulin ratio, coagulation studies, electrocardiogram to monitor for hyperkalemia, and abdominal girth should be thoroughly assessed daily or more often based on the clinical need. Treatment, consisting of limited intravenous fluids, electrolytes, and human serum albumin is intended to normalize electrolytes while maintaining an acceptable but somewhat reduced intravascular volume. Full correction of the intravascular volume deficit may lead to an unacceptable increase in the amount of third space fluid accumulation. Chronic Phase: After the acute phase is successfully managed as above, excessive fluid accumulation in the third space should be limited by instituting severe potassium, sodium, and fluid restriction. Resolution Phase: As third space fluid returns to the intravascular compartment, a fall in hematocrit and increasing urinary output are observed in the absence of any increase in intake. Peripheral and/or pulmonary edema may result if the kidneys are unable to excrete third space fluid as rapidly as it is mobilized. Diuretics may be indicated during the resolution phase, if necessary, to combat pulmonary edema. OHSS increases the risk of injury to the ovary. The ascitic, pleural, and pericardial fluid should not be removed unless there is the necessity to relieve symptoms such as pulmonary distress or cardiac tamponade. Pelvic examination may cause rupture of an ovarian cyst, which may result in hemoperitoneum, and should therefore be avoided. If bleeding occurs and requires surgical intervention, the clinical objective should be to control the bleeding and retain as much ovarian tissue as possible. During clinical trials with FOLLISTIM or FOLLISTIM AQ Cartridge therapy, OHSS occurred in 7.6% of 105 women (OI) and 6.4% of 751 women (IVF or ICSI) treated with FOLLISTIM and FOLLISTIM AQ Cartridge, respectively.

5.3 Pulmonary and Vascular Complications Serious pulmonary conditions (e.g., atelectasis, acute respiratory distress syndrome) have been reported in women treated with gonadotropins. In addition, thromboembolic reactions both in association with, and separate from OHSS have been reported following gonadotropin therapy. Intravascular thrombosis, which may originate in venous or arterial vessels, can result in reduced blood flow to vital organs or the extremities. Women with generally recognized risk factors for thrombosis, such as a personal or family history, severe obesity, or thrombophilia, may have an increased risk of venous or arterial thromboembolic events, during or following treatment with gonadotropins. Sequelae of such reactions have included venous thrombophlebitis, pulmonary embolism, pulmonary infarction, cerebral vascular occlusion (stroke), and arterial occlusion resulting in loss of limb and rarely in myocardial infarction. In rare cases, pulmonary complications and/or thromboembolic reactions have resulted in death. In women with recognized risk factors, the benefits of ovulation induction, in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) treatment need to be weighed against the risks. It should be noted that pregnancy itself also carries an increased risk of thrombosis. […]

6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of FOLLISTIM and/or FOLLISTIM AQ Cartridge. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Gastrointestinal disorders Abdominal distension, abdominal pain, constipation, diarrhea General disorders and administration site conditions Injection site reaction Immune system disorders Hypersensitivity reactions including anaphylaxis, pruritus, rash, and urticaria Reproductive system and breast disorders Breast tenderness, metrorrhagia, ovarian enlargement, vaginal hemorrhage Skin and subcutaneous tissue disorders Rash Vascular disorders Thromboembolism [see Warnings and Precautions (5.3) ]

No drug-drug interaction studies have been performed.

Lactation: It is not known whether this drug is excreted in human milk. ( 8.2 )

8.1 Pregnancy Risk Summary FOLLISTIM AQ Cartridge is contraindicated for use in pregnant women. The incidence of congenital malformations after some Assisted Reproductive Technology, specifically in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI)], may be slightly higher than that 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 a higher incidence of multi-fetal gestations after IVF or ICSI [see Warnings and Precautions (5.6) ] . There is no human data that the use of gonadotropins (including FOLLISTIM AQ Cartridge) alone or as part of IVF or ICSI cycles, increases the risk of congenital malformations. The risk of spontaneous abortion (miscarriage) is increased in women who have used gonadotropins products to achieve pregnancy [see Warnings and Precautions (5.8) ] . In the US general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.

8.2 Lactation Risk Summary It is not known whether this drug is excreted in human milk. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for FOLLISTIM AQ Cartridge and any potential adverse effects on the breastfed child from FOLLISTIM AQ Cartridge or from the underlying maternal condition.

8.4 Pediatric Use FOLLISTIM AQ Cartridge is not indicated for use in pediatric patients. Clinical studies have not been conducted in the pediatric population.

8.5 Geriatric Use Clinical studies of FOLLISTIM AQ Cartridge have not been conducted in patients 65 years of age and older.

Women: Follicle-stimulating hormone (FSH), the active component in FOLLISTIM AQ Cartridge, is required for normal follicular growth, maturation, and gonadal steroid production. In women, the level of FSH is critical for the onset and duration of follicular development, and consequently for the timing and number of follicles reaching maturity. FOLLISTIM AQ Cartridge stimulates ovarian follicular growth in women who do not have primary ovarian failure. In order to effect the final phase of follicle maturation, resumption of meiosis and rupture of the follicle in the absence of an endogenous LH surge, human chorionic gonadotropin (hCG) must be given following treatment with FOLLISTIM AQ Cartridge when patient monitoring indicates appropriate follicular development parameters have been reached. Men: FOLLISTIM when administered with hCG stimulates spermatogenesis in men with hypogonadotropic hypogonadism. FSH, the active component of FOLLISTIM, is the pituitary hormone responsible for spermatogenesis.
