6.1 Clinical

Study 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. 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, 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. All women received pituitary down-regulation with gonadotropin releasing hormone (GnRH) agonist before stimulation. Adverse Reactions occurring in at least 2.0% of women are listed in Table 2.

6.2 Postmarketing

Experience The following adverse reactions have been reported during postmarketing use of GONAL-f ® RFF. Because these reactions were reported voluntarily from a population of uncertain size, the frequency or a causal relationship to GONAL - f ® RFF cannot be reliably determined. Body as a Whole - General: hypersensitivity reactions including anaphylactoid reactions Respiratory System: asthma Vascular disorders: thromboembolism
