Incompatibilities

In the absence of compatibility studies, this medicinal product must not be mixed with other medicinal products.

Undesirable effects

The following serious adverse reactions are discussed elsewhere in the labeling:

• Hypersensitivity and Anaphylactic Reactions
• Abnormal Ovarian Enlargement
• Ovarian Hyperstimulation Syndrome
• Thromboembolic events
• Ovarian Torsion
• Multi-fetal Gestation and Birth
• Congenital Malformations
• Ectopic Pregnancy
• Spontaneous Abortion
• Ovarian Neoplasms

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 BRAVELLE® was examined in four clinical studies that enrolled a total of 222 women who received BRAVELLE®.

In a randomized, multi-center, active controlled study, a total of 72 women received BRAVELLE® (35 in a subcutaneous administration arm and 37 in an intramuscular administration arm) for induction of ovulation. Adverse reactions occurring at an incidence of ≥ 2% incidence in women receiving BRAVELLE® are shown in Table 1.

Table 1: Ovulation Induction Safety Profile

Three studies examined the safety profile of BRAVELLE® in ART. A total of 150 women received treatment with BRAVELLE® in these studies. Adverse reactions occurring at an incidence of ≥ 2% incidence for this integrative assessment are presented in Table 2.

Preclinical safety data

Non-clinical data reveal no special hazard for humans based on conventional studies of single and repeated dose toxicity and genotoxicity additional to that already stated in other sections of this SmPC.

In rabbits, the formulation reconstituted with 0.9 % benzyl alcohol and 0.9 % benzyl alcohol alone, both resulted in a slight haemorrhage and subacute inflammation after single subcutaneous injection or mild inflammatory and degenerative changes after single intramuscular injection respectively.

Impaired fertility has been reported in rats exposed to pharmacological doses of follitropin alfa (> 40 IU/kg/day) for extended periods, through reduced fecundity.

Given in high doses (> 5 IU/kg/day) follitropin alfa caused a decrease in the number of viable foetuses without being a teratogen, and dystocia similar to that observed with urinary Menopausal Gonadotropin (hMG). However, since GONAL-f is not indicated in pregnancy, these data are of limited clinical relevance.

Pharmacotherapeutic group

Pharmacodynamic properties

Pharmacotherapeutic group: Sex hormones and modulators of the genital systems, gonadotropins, ATC code: G03GA05.

In women, the most important effect resulting from parenteral administration of FSH is the development of mature Graafian follicles. In women with anovulation, the object of GONAL-f therapy is to develop a single mature Graafian follicle from which the ovum will be liberated after the administration of hCG.

Clinical efficacy and safety in women

In clinical trials, patients with severe FSH and LH deficiency were defined by an endogenous serum LH level < 1.2 IU/L as measured in a central laboratory. However, it should be taken into account that there are variations between LH measurements performed in different laboratories.

In clinical studies comparing r-hFSH (follitropin alfa) and urinary FSH in ART (see table below) and in ovulation induction, GONAL-f was more potent than urinary FSH in terms of a lower total dose and a shorter treatment period needed to trigger follicular maturation.

In ART, GONAL-f at a lower total dose and shorter treatment period than urinary FSH, resulted in a higher number of oocytes retrieved when compared to urinary FSH.

Table: Results of study GF 8407 (randomised parallel group study comparing efficacy and safety of GONAL-f with urinary FSH in assisted reproduction technologies)

Differences between the 2 groups were statistically significant (p< 0.05) for all criteria listed.

Clinical efficacy and safety in men

In men deficient in FSH, GONAL-f administered concomitantly with hCG for at least 4 months induces spermatogenesis.

Pharmacotherapeutic group: Sex hormones and modulators of the genital systems, gonadotropins, ATC code: G03GA05.

Pharmacokinetic properties

Following intravenous administration, follitropin alfa is distributed to the extracellular fluid space with an initial half-life of around 2 hours and eliminated from the body with a terminal half-life of about one day. The steady state volume of distribution and total clearance are 10 l and 0.6 l/h, respectively. One-eighth of the follitropin alfa dose is excreted in the urine.

Following subcutaneous administration, the absolute bioavailability is about 70 %. Following repeated administration, follitropin alfa accumulates 3-fold achieving a steady-state within 3-4 days. In women whose endogenous gonadotropin secretion is suppressed, follitropin alfa has nevertheless been shown to effectively stimulate follicular development and steroidogenesis, despite unmeasurable LH levels.

Single doses of 225 International Units and multiple daily doses (7 days) of 150 International Units of BRAVELLE® were administered to healthy volunteer female subjects while their endogenous FSH was suppressed. Sixteen subjects received BRAVELLE® subcutaneously and 12 received the drug intramuscularly. Serum FSH concentrations were determined. Based on the steady state ratio of FSH C max and AUC, subcutaneous and intramuscular administration of BRAVELLE® were not bioequivalent. Multiple doses of BRAVELLE® intramuscular resulted in C max and AUC of 77.7% and 81.8% compared to multiple doses of BRAVELLE® subcutaneous. The FSH pharmacokinetic parameters for single and multiple dose BRAVELLE®, administered subcutaneously and intramuscularly are in Table 3.

Table 3: FSH Pharmacokinetic Parameters (Mean ± SD) Following BRAVELLE® Administration

The subcutaneous route of administration trends toward greater bioavailability than the IM route for single and multiple doses of BRAVELLE®.

Human tissue or organ distribution of FSH has not been studied for BRAVELLE®.

Metabolism of FSH has not been studied for BRAVELLE® in humans.

The mean elimination half-lives of FSH for subcutaneous and intramuscular single dosing are 31.8 and 37 hours, respectively. However, following multiple dosing (X 7 days) they are 20.6 and 15.2 hours for SC and IM, respectively.
