Gonal-f RFF Redi-ject

1 INDICATIONS AND USAGE GONAL-f ® RFF Redi-ject ® is a prefilled gonadotropin-containing auto-injection device indicated for: Induction of ovulation and pregnancy in oligo-anovulatory women in whom the cause of infertility is functional and not due to primary ovarian failure ( 1.1 ) Development of multiple follicles in ovulatory women as part of an Assisted Reproductive Technology (ART) cycle ( 1.2 ) 1.1 Induction of Ovulation and Pregnancy in Oligo-Anovulatory Women in whom the Cause of Infertility is Functional and Not Due to Primary Ovarian Failure. Prior to initiation of treatment with GONAL-f ® RFF Redi-ject ® : Perform a complete gynecologic and endocrinologic evaluation Exclude primary ovarian failure Exclude the possibility of pregnancy Demonstrate tubal patency Evaluate the fertility status of the male partner 1.2 Development of Multiple Follicles in Ovulatory Women as Part of an Assisted Reproductive Technology (ART) Cycle. Prior to initiation of treatment with GONAL-f ® RFF Redi-ject ® : 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

2 DOSAGE AND ADMINISTRATION Ovulation Induction ( 2.2 ) Initial starting dose of the first cycle - 75 International Units of GONAL-f ® RFF Redi-ject ® per day for 14 days, administered subcutaneously Individualization doses after 14 days Doses larger than 300 International Units of FSH per day are not recommended Assisted Reproductive Technology ( 2.3 ) Initial starting dose of the first cycle - 150 International Units per day, administered subcutaneously Dosage adjustments after 3-5 days and by 75-150 International Units at each adjustment Do not administer doses greater than 450 International Units per day 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. GONAL-f ® RFF Redi-ject ® is a pre-filled disposable auto-injection device intended for multiple dose use. GONAL-f ® RFF Redi-ject ® can be set in 12.5 International Units increments. Administer GONAL-f ® RFF Redi-ject ® subcutaneously in the abdomen as described in Instructions for Use Do not attempt to mix any other medications inside of the device with GONAL-f ® RFF Redi-ject ® . Instruct women to remove the GONAL-f ® RFF Redi-ject ® from the refrigerator at least 30 minutes prior to use in order to allow GONAL-f ® RFF Redi-ject ® to warm to room temperature and avoid the discomfort of a cold injection. 2.2 Recommended Dosing for Ovulation Induction The dosing scheme is stepwise and is individualized for each woman [see Clinical Studies (14.1) ] . Starting doses less than 37.5 International Units have not been studied in clinical trials and are not recommended. A starting daily dose of 75 International Units of GONAL-f ® RFF Redi-ject ® is administered subcutaneously daily for 14 days in the first cycle of use. In subsequent cycles of treatment, the starting dose (and dosage adjustments) of GONAL-f ® RFF Redi-ject ® should be determined based on the history of the ovarian response to GONAL-f ® RFF Redi-ject ® . The following should be considered when planning the woman's individualized dose: Appropriate GONAL-f ® RFF Redi-ject ® dose adjustment(s) should be used to prevent multiple follicular growth and cycle cancellation. The maximum, individualized, daily dose of GONAL-f ® RFF Redi-ject ® is 300 International Units per day. In general, do not exceed 35 days of treatment. If indicated by the ovarian response after the initial 14 days, make an incremental adjustment in dose, up to 37.5 International Units. If indicated by the ovarian response, make additional adjustments in dose, up to 37.5 International Units, every 7 days. Treatment should continue until follicular growth and/or serum estradiol levels indicate an adequate ovarian response. When pre-ovulatory conditions are reached, administer human chorionic gonadotropin (hCG) to induce final oocyte maturation and ovulation. Withhold hCG in cases where the ovarian monitoring suggests an increased risk of ovarian hyperstimulation syndrome (OHSS) on the last day of GONAL-f ® RFF Redi-ject ® therapy [see Warnings and Precautions (5.2 , 5.3 , 5.11) ] . Encourage the woman and her partner to have intercourse daily, beginning on the day prior to the administration of hCG and until ovulation becomes apparent. Discourage intercourse when the risk for OHSS is increased [see Warnings and Precautions (5.2 , 5.3) ] . 2.3 Recommended Dosing for Assisted Reproductive Technology The dosing scheme follows a stepwise approach and is individualized for each woman. Beginning on cycle day 2 or 3, a starting dose of 150 International Units of GONAL-f ® RFF Redi-ject ® is administered subcutaneously daily until sufficient follicular development, as determined by ultrasound in combination with measurement of serum estradiol levels, is attained. In most cases, therapy should not exceed 10 days. In women under 35 years of age whose endogenous gonadotropin levels are suppressed, initiate GONAL-f ® RFF Redi …

The safety of GONAL-f ® RFF was examined in two clinical studies (one ovulation induction study and one ART study). Ovulation Induction In a multiple cycle (3), assessor-blind, multinational, multicenter, active comparator study vs. a recombinant FSH comparator, a total of 83 oligo-anovulatory infertile women were randomized and underwent ovulation induction with GONAL-f ® RFF. Adverse reactions occurring in at least 2.0% of women receiving GONAL-f ® RFF are listed in Table 1. Table 1: Common Adverse Reactions Reported at a Frequency of ≥ 2% in an Ovulation Induction Study System Organ Class/Adverse Reactions GONAL-f ® RFF N=83 total number of women treated with GONAL-f ® RFF (176 treatment cycles up to 3 treatment cycles per woman ) n number of women with the adverse reaction (%) Central and Peripheral Nervous System Headache 22 (26.5%) Gastrointestinal System Abdominal Pain 10 (12.0%) Nausea 3 (3.6%) Flatulence 3 (3.6%) Diarrhea 3 (3.6%) Neoplasm Ovarian Cyst 3 (3.6%) Reproductive, Female Ovarian Hyperstimulation 6 (7.2%) Application Site Injection Site Pain 4 (4.8%) Injection Site Inflammation 2 (2.4%) Assisted Reproductive Technology In a single cycle, assessor-blind, multinational, multicenter, active comparator study vs. a recombinant FSH comparator, a total of 237 normal ovulatory infertile women were randomized and received GONAL-f ® RFF as part of an ART [in vitro fertilization (IVF) or intracytoplasmic sperm injection cycle (ICSI)] cycle.

7 DRUG INTERACTIONS No drug-drug interaction studies have been performed.

8 USE IN SPECIFIC POPULATIONS Do not use GONAL-f ® RFF Redi-ject ® in pregnant women ( 4 , 8.1 ), Nursing Mothers: It is not known whether this drug is excreted in human milk. ( 8.3 ) Pediatric Use: Safety and efficacy not established. ( 8.4 ) Renal and Hepatic Insufficiency: Safety, efficacy, and pharmacokinetics of GONAL-f ® RFF Redi-ject ® in women with renal or hepatic insufficiency have not been established. ( 8.6 ) 8.1 Pregnancy Risk Summary GONAL-f ® RFF Redi-ject ® is not indicated in pregnant women. The incidence of congenital malformations after some Assisted Reproductive Technology (ART), procedures, 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 a higher incidence of multi-fetal gestations after IVF or ICSI. There is no human data that the use of gonadotropins (including GONAL-f ® RFF Redi-ject ® ), 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 (including GONAL-f ® RFF Redi-ject ® ) to achieve pregnancy. In animal studies, the continuous administration of recombinant human FSH during pregnancy resulted in a decrease in the number of viable fetuses and difficult and prolonged delivery. No teratogenic effect has been observed. In the US general population, the estimated background risk of major birth defects and miscarriage after spontaneous clinically recognized pregnancies, is 2% to 4% and 15% to 20%, respectively. Data Human Data Data on a limited number of exposed pregnancies indicate no adverse reactions of gonadotropins on pregnancy, embryonal or fetal development, parturition or postnatal development following controlled ovarian stimulation. Animal Data Embryofetal development studies with recombinant human FSH in rats, where dosing occurred during organogenesis, showed a dose dependent increase in difficult and prolonged parturition in dams, and dose dependent increases in resorptions, pre- and post-implantation losses, and stillborn pups at doses representing 5 and 41 times the lowest clinical dose of 75 IU based on body surface area. Pre-/post-natal development studies with recombinant human FSH in rats, where dosing occurred from mid-gestation through lactation, showed difficult and prolonged parturition in all dams dosed at 41 times the lowest clinical dose of 75 IU based on body surface area, along with maternal death and stillborn pups associated with the difficult and prolonged parturition. This toxicity was not observed in dams and offspring dosed at a level 5 times the lowest clinical dose of 75 IU based on body surface area. 8.2 Lactation There are no data on the presence of GONAL-F RFF in human milk, the effects on the breastfed infant, or the effects on milk production. Because the secretion of prolactin during lactation can result in inadequate response to ovarian stimulation, advise women not to breast feed during treatment with GONAL-f ® RFF Redi-ject ® . 8.3 Females and Males of Reproductive Potential Since GONAL-f ® RFF Redi-ject ® is not indicated in pregnant women, verify a negative pregnancy test before administering GONAL-f ® RFF Redi-ject ® to a woman [see Dosage and Administration (2.2 , 2.3) ]. 8.4 Pediatric Use Safety and effectiveness in pediatric patients have not been established. 8.6 Renal and Hepatic Insufficiency Safety, efficacy, and pharmacokinetics of GONAL-f ® RFF Redi-ject ® in women with renal or hepatic insufficiency have not been established.

12.1 Mechanism of Action Follicle stimulating hormone (FSH), the active component in GONAL-f ® RFF Redi-ject ® , is required for normal follicular growth, follicular maturation, and gonadal steroid production. 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. GONAL-f ® RFF Redi-ject ® 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 GONAL-f ® RFF Redi-ject ® when monitoring of the woman indicates that appropriate follicular development parameters have been achieved. There is inter-woman variability in response to FSH administration.

11 DESCRIPTION Follitropin alfa, a gonadotropin [human follicle stimulating hormone (hFSH)], is a glycoprotein hormone produced by recombinant DNA technology in a Chinese Hamster Ovary (CHO) cell line. It has a dimeric structure consisting of two glycoprotein subunits (alpha and beta). The alpha and beta subunits have 92 and 111 amino acids, respectively, and their primary and tertiary structures are indistinguishable from those of human follicle stimulating hormone. The molecular weight is approximately 31 kDa (14 kDa for alpha subunit and 17 kDa for beta subunit). GONAL-f ® RFF Redi-ject ® (follitropin alfa) injection is a sterile, clear and colorless to slightly yellow solution in disposable, prefilled single-patient-use pen intended for the subcutaneous use. Each GONAL-f ® RFF Redi-ject ® pen delivers 300 International Units (22 mcg) follitropin alfa in 0.48 mL and the inactive ingredients: dibasic sodium phosphate (0.43 mg), m-cresol (1.47 mg), methionine (0.05 mg), monobasic sodium phosphate (0.19 mg), poloxamer (0.05 mg), sucrose (29.47 mg) and Water for Injection USP. Phosphoric acid and/or sodium hydroxide may be used to adjust the pH to 7. Each GONAL-f ® RFF Redi-ject ® pen delivers 450 International Units (33 mcg) follitropin alfa in 0.72 mL and the inactive ingredients: dibasic sodium phosphate (0.65 mg), m-cresol (2.21 mg), methionine (0.07 mg), monobasic sodium phosphate (0.29 mg), poloxamer (0.07 mg), sucrose (44.20 mg) and Water for Injection USP. Phosphoric acid and/or sodium hydroxide may be used to adjust the pH to 7. Each GONAL-f ® RFF Redi-ject ® pen delivers 900 International Units (66 mcg) follitropin alfa in 1.44 mL and the inactive ingredients: dibasic sodium phosphate (1.3 mg), m-cresol (4.42 mg), methionine (0.15 mg), monobasic sodium phosphate (0.58 mg), poloxamer (0.15 mg), sucrose (88.41 mg) and Water for Injection USP. Phosphoric acid and/or sodium hydroxide may be used to adjust the pH to 7. Under current storage conditions, GONAL-f ® RFF Redi-ject ® may contain up to 10% of oxidized follitropin alfa.

10 OVERDOSAGE Aside from possible OHSS [see Warnings and Precautions (5.3) ] and multiple gestations [see Warnings and Precautions (5.6) ], there is no additional information on the consequences of acute overdosage with GONAL-f ® RFF Redi-ject ® .
