`
` 3 DOSAGE FORMS AND STRENGTHS
`
`
`
` FASLODEX, an injection for intramuscular administration, is supplied as 5-mL prefilled syringes
`
` containing 50 mg/mL fulvestrant.
`
`
`
` 4 CONTRAINDICATIONS
`
` FASLODEX is contraindicated in patients with a known hypersensitivity to the drug or to any of its
`
`
`
` components. Hypersensitivity reactions, including urticaria and angioedema, have been reported in
`
` association with FASLODEX [see Adverse Reactions (6.2)].
`
`
`
`
`
`
` 5 WARNINGS AND PRECAUTIONS
`
` 5.1 Risk of Bleeding
`
` Because FASLODEX is administered intramuscularly, it should be used with caution in patients with
`
`
`
` bleeding diatheses, thrombocytopenia, or anticoagulant use.
`
`
`
`
`
`Reference ID: 3895794
`
`
`

`
`

`

` 5.2 Increased Exposure in Patients with Hepatic Impairment
`
` The safety and pharmacokinetics of FASLODEX were evaluated in a study in seven subjects with
`
`
`
`
` moderate hepatic impairment (Child-Pugh class B) and seven subjects with normal hepatic function.
`
` Exposure was increased in patients with moderate hepatic impairment, therefore a dose of 250 mg is
`
` recommended [see Dosage and Administration (2.2)].
`
`
`FASLODEX has not been studied in patients with severe hepatic impairment (Child-Pugh class C) [see
`
`
`Use in Specific Populations (8.6)].
`
`
`
` 5.3 Embryo-Fetal Toxicity
` Based on findings from animal studies and its mechanism of action, FASLODEX can cause fetal harm
`
`
`
`
`
` when administered to a pregnant woman. In animal reproduction studies, administration of fulvestrant to
` pregnant rats and rabbits during organogenesis resulted in embryo-fetal toxicity at daily doses that are
`
`
`
`
`
` significantly less than the maximum recommended human dose. Advise pregnant women of the potential
`
` risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment
`
`
`
` with FASLODEX and for one year after the last dose [see Use in Specific Populations (8.1), (8.3) and
`
`
`
`
`Clinical Pharmacology (12.1)].
`
`
`
`
`
`
` 6 ADVERSE REACTIONS
`
`
`
` The following adverse reactions are discussed in more detail in other sections of the labeling:
`
`
`
`
`
`
`
` • Risk of Bleeding [see Warnings and Precautions (5.1)]
`
`
`Increased Exposure in Patients with Hepatic Impairment [see Warnings and Precautions (5.2)]

`
`
`•
`• Embryo-Fetal Toxicity [see Warnings and Precautions (5.3)]
`
`
`
`
` 6.1 Clinical Trials Experience
`
`
`
` Because clinical trials are conducted under widely varying conditions, the adverse reaction rates observed
`
` cannot be directly compared to rates in other trials and may not reflect the rates observed in clinical
`
`
` practice.
`
`
`
`
`
` Monotherapy
`
`Comparison of FASLODEX 500 mg and FASLODEX 250 mg
`
`
`
`
`The following adverse reactions (ARs) were calculated based on the safety analysis of Study 1 comparing
`
`
`
`the administration of FASLODEX 500 mg intramuscularly once a month with FASLODEX 250 mg
`
`intramuscularly once a month. The most frequently reported adverse reactions in the fulvestrant 500 mg
`
`
`
`group were injection site pain (11.6% of patients), nausea (9.7% of patients) and bone pain (9.4% of
`
`
`
`patients); the most frequently reported adverse reactions in the fulvestrant 250 mg group were nausea
`
`
`
`(13.6% of patients), back pain (10.7% of patients) and injection site pain (9.1% of patients).
`
`

`
`In the pooled safety population (N=1127) from clinical trials comparing FASLODEX 500 mg to
`
`FASLODEX 250 mg, post-baseline increases of ≥1 CTC grade in either AST, ALT, or alkaline
`
`phosphatase were observed in >15% of patients receiving FASLODEX. Grade 3-4 increases were
`
`observed in 1-2% of patients. The incidence and severity of increased hepatic enzymes (ALT, AST, ALP)
`
`did not differ between the 250 mg and the 500 mg FASLODEX arms.
`
`
`
`Comparison of FASLODEX 250 mg and Anastrozole 1 mg in Combined Trials (Studies 2 and 3)
`
`
`
`
`
`
`
`
`The most commonly reported adverse reactions in the FASLODEX and anastrozole treatment groups
`were gastrointestinal symptoms (including nausea, vomiting, constipation, diarrhea and abdominal pain),
`
`
`
`headache, back pain, vasodilatation (hot flashes), and pharyngitis.
`
`
`
`
`Injection site reactions with mild transient pain and inflammation were seen with FASLODEX and
`occurred in 7% of patients (1% of treatments) given the single 5 mL injection (predominantly European
`
`
`
`
`
`Trial Study 3) and in 27% of patients (4.6% of treatments) given the 2 x 2.5 mL injections (North
`
`American Trial Study 2).
`
`
`
`
`Table 2 lists adverse reactions reported with an incidence of 5% or greater, regardless of assessed
`
`
`
`
`causality, from the two controlled clinical trials comparing the administration of FASLODEX 250 mg
`
`intramuscularly once a month with anastrozole 1 mg orally once a day.

`1. All patients on FASLODEX received injections, but only those anastrozole patients who were in the North
`
`
`
`
`American Study 2 received placebo injections.
`
`
`
`
` Combination Therapy with Palbociclib
`
`
`
`
`
`
`
`
`
`
`The safety of FASLODEX (500 mg) plus palbociclib (125 mg/day) versus FASLODEX plus placebo was
`
`
`
`evaluated in Study 4. The data described below reflect exposure to FASLODEX plus palbociclib in
`
`
`
`
`345 out of 517 patients with HR-positive, HER2-negative advanced or metastatic breast cancer who
`
`
`
`received at least 1 dose of treatment in Study 4.
`
`
`
`
`No dose reduction was allowed for FASLODEX in Study 4. Dose reductions of palbociclib due to an
`
`
`
`
`adverse reaction of any grade occurred in 36% of patients receiving FASLODEX plus palbociclib.
`
`
`
`
`
`Permanent discontinuation associated with an adverse reaction occurred in 19 of 345 (6%) patients
`
`
`
`receiving FASLODEX plus palbociclib, and in 6 of 172 (3%) patients receiving FASLODEX plus
`
`
`
`placebo. Adverse reactions leading to discontinuation for those patients receiving FASLODEX plus
`
`
`
`
`
`palbociclib included fatigue (0.6%), infections (0.6%), and thrombocytopenia (0.6%).
`
`
`
`
`
`The most common adverse reactions (≥10%) of any grade reported in patients in the FASLODEX plus
`palbociclib arm were neutropenia, leukopenia, infections, fatigue, nausea, anemia, stomatitis, headache,
`
`
`
`diarrhea, thrombocytopenia, constipation, vomiting, alopecia, rash, decreased appetite, and pyrexia.
`
`
`The most frequently reported serious adverse reactions in patients receiving FASLODEX plus palbociclib
`
`
`
`
`
`
`were infections (3%), pyrexia (1%), neutropenia (1%), and pulmonary embolism (1%).
`
`
`
`Adverse reactions reported in patients who received FASLODEX plus palbociclib in Study 4 are listed in
`
`
`
`
`
`Table 3, and laboratory abnormalities are listed in Table 4.

`
`
` For FASLODEX 250 mg, other adverse reactions reported as drug-related and seen infrequently (<1%)
`
` include thromboembolic phenomena, myalgia, vertigo, leukopenia, and hypersensitivity reactions
`
` including angioedema and urticaria.
`
` Vaginal bleeding has been reported infrequently (<1%), mainly in patients during the first 6 weeks after
`
`
`
`
`
` changing from existing hormonal therapy to treatment with FASLODEX. If bleeding persists, further
`
` evaluation should be considered.
`
`
`
`
`
` Elevation of bilirubin, elevation of gamma GT, hepatitis, and liver failure have been reported infrequently
`
` (<1%).
`
`
`
` 7 DRUG INTERACTIONS
`
`
` There are no known drug-drug interactions. Although, fulvestrant is metabolized by CYP 3A4 in vitro,
`
` drug interactions studies with ketoconazole or rifampin did not alter fulvestrant pharmacokinetics. Dose
`
`
` adjustment is not needed in patients co-prescribed CYP 3A4 inhibitors or inducers [see Clinical
`
`
`
`
`Pharmacology (12.3)].
`
`
`
`
`
`
` 8 USE IN SPECIFIC POPULATIONS
`
`
` 8.1 Pregnancy
`
` Risk Summary
`
`Based on findings from animal studies and its mechanism of action, FASLODEX can cause fetal harm
`
`
`
`when administered to a pregnant woman [see Clinical Pharmacology (12.1)]. There are no available data
`
`
`
`
`in pregnant women to inform the drug-associated risk. In animal reproduction studies, administration of
`
`fulvestrant to pregnant rats and rabbits during organogenesis caused embryo-fetal toxicity, including
`
`
`skeletal malformations and fetal loss, at daily doses that were 6% and 30% of the maximum
`
`
`
`
`recommended human dose based on mg/m2, respectively [see Data]. Advise pregnant women of the
`
`
`
`potential risk to a fetus.
`
`
`
`
`The estimated background risk of major birth defects and miscarriage for the indicated population is
`
`
`
`
`
`
`
`unknown. In the U.S. general population, the estimated background risk of major birth defects and
`
`
`miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.

`
`

`

`
`
` Data
`
`Animal Data
`
`
`Administration of fulvestrant to rats prior to and up to implantation caused embryonic loss at daily doses
`
`
`
`that were 0.6% of the daily maximum recommended human dose based on mg/m2. When fulvestrant was
`
`
`
`
`administered to pregnant rats during the period of organogenesis, intramuscular doses ≥0.1 mg/kg/day
`(6% of the human recommended dose based on mg/m2) caused effects on embryo-fetal development
`
`
`
`
`
`consistent with its antiestrogenic activity. Fulvestrant caused an increased incidence of fetal abnormalities
`in rats (tarsal flexure of the hind paw at 2 mg/kg/day; equivalent to the human dose based on mg/m2) and
`
`
`
`
`
`
`
`non-ossification of the odontoid and ventral tubercle of the first cervical vertebra at doses ≥0.1
`
`
`mg/kg/day. Fulvestrant administered at 2 mg/kg/day caused fetal loss.
`
`
`
`When administered to pregnant rabbits during the period of organogenesis, fulvestrant caused pregnancy
`loss at an intramuscular dose of 1 mg/kg/day (equivalent to the human dose based on mg/m2). Further, at
`
`
`
`
`0.25 mg/kg/day (30% the human dose based on mg/m2), fulvestrant caused increases in placental weight
`
`
`
`
`
`
`
`and post-implantation loss in rabbits. Fulvestrant was associated with an increased incidence of fetal
`
`
`
`
`variations in rabbits (backwards displacement of the pelvic girdle, and 27 pre-sacral vertebrae at 0.25
`mg/kg/day; 30% the human dose based on mg/m2) when administered during the period of organogenesis.
`
`
`
`
` 8.2 Lactation
`
`
` Risk Summary
`
`There is no information regarding the presence of fulvestrant in human milk, nor of its effects on milk
`
`
`
`
`
`production or breast-fed infant. Fulvestrant can be detected in rat milk [see Data]. Because of the
`
`
`
`potential for serious adverse reactions in breast-fed infants from FASLODEX, advise a lactating woman
`
`
`
`not to breast-feed during treatment with FASLODEX and for one year after the final dose.
`
`
`Data
`
`
`Levels of fulvestrant were approximately 12-fold higher in milk than in plasma after exposure of lactating
`
`
`rats to a dose of 2 mg/kg. Drug exposure in rodent pups from fulvestrant-treated lactating dams was
`
`
`
`estimated as 10% of the administered dose. In a study in rats of fulvestrant at 10 mg/kg given twice or 15
`
`
`
`
`
`
`mg/kg given once (less than the recommended human dose based on mg/m2) during lactation, offspring
`
`
`
`
`survival was slightly reduced.
`
`
`
` 8.3 Females and Males of Reproductive Potential
`
` Pregnancy Testing
`
`
`
`Pregnancy testing is recommended for females of reproductive potential within seven days prior to
`
`
`initiating FASLODEX.
`
`
`Contraception
`
`
`Females
`
`
`
`
`Reference ID: 3895794
`
`
`
` 12
`
`

`

` FASLODEX can cause fetal harm when administered to a pregnant woman [see Use in Specific
`
`
`
`
`
`Populations (8.1)]. Advise females of reproductive potential to use effective contraception during
`
`
`
`treatment and for one year after the last dose.
`
`
`
`
`
`
`Infertility
`
`
`Based on animal studies, FASLODEX may impair fertility in females and males of reproductive potential.
`
`
`
`
`
`
`The effects of fulvestrant on fertility were reversible in female rats [see Nonclinical Toxicology (13.1)].
`
`
`
`
`
`
`
`
`
` 8.4 Pediatric Use
`
`
`
`
`
` Safety and effectiveness in pediatric patients have not been established. A multi-center, single-arm, open-
` label, study of fulvestrant was conducted in 30 girls with McCune-Albright Syndrome (MAS) associated
`
`
`
`
`
` with progressive precocious puberty (PPP). The median age at informed consent was 6 years old (range: 1
`
`
`
`
`
` to 8).
`
` The first 10 patients initially received fulvestrant 2 mg/kg. Based on PK data from the first 6 patients, all
`
`
`
`
`
` 10 patients receiving 2 mg/kg were escalated to a dose of 4 mg/kg and all other patients received 4 mg/kg
`
` from study entry.
`
`
`
` Baseline measurements for vaginal bleeding days, bone age, growth velocity, and Tanner staging for at
` least 6 months prior to study entry were provided retrospectively by the parent, guardian or local
`
`
`
`
` consultant. All measurements during the study period were collected prospectively. Patients’ baseline
`
`
`
` characteristics included the following: a mean ± SD chronological age of 5.9 ± 1.8 years; a mean rate of
`
`
`
`
`
` bone age advancement (change in bone age in years divided by change in chronological age in years) of
`
`
` 2.0 ± 1.03; and a mean growth velocity z-score of 2.4 ± 3.26.
`
`
`
`
`
`
`
`
` Twenty-nine of 30 patients completed the 12-month study period. The following results were observed:
` 35% (95% CI: 16%, 57%) of the 23 patients with baseline vaginal bleeding experienced a complete
`
`
`
`
`
`
` cessation of vaginal bleeding on-treatment (month 0 to 12); a reduction in the rate of bone age
` advancement during the 12-month study period compared to baseline (mean change = -0.9 [95% CI: -1.4,
`
`
`
` -0.4]); and a reduction in mean growth velocity Z-score on-treatment compared to baseline (mean change
` = -1.1 [95% CI: -2.7, 0.4]). There were no clinically meaningful changes in median Tanner stage (breast
`
`
`
`
` or pubic), mean uterine volume, or mean ovarian volume, or predicted adult height (PAH) on-treatment
` compared to baseline. The effect of FASLODEX on bone mineral density in children has not been studied
`
`
`
`
` and is not known.
`
`
`
`
`
` Eight patients (27%) experienced adverse reactions that were considered possibly related to FASLODEX.
`
` These included injection site reactions (inflammation, pain, hematoma, pruritus, rash), abdominal pain,
` contusion, tachycardia, hot flush, extremity pain, and vomiting. Nine (30.0%) patients reported an SAE,
`
`
` none of which were considered related to FASLODEX. No patients discontinued study treatment due to
`
`
`
`
` an AE and no patients died.
`
`
`
`
` Pharmacokinetics
`
` The pharmacokinetics of fulvestrant was characterized using a population pharmacokinetic analysis with
`
`
`
` sparse samples per patient obtained from 30 female pediatric patients aged 1 to 8 years with PPP
`
`
`
`
`
`Reference ID: 3895794
`
`

`
`

`

` associated with MAS. Pharmacokinetic data from 294 postmenopausal women with breast cancer who
`
`
`
`
` received 125 or 250 mg monthly dosing regimen were also included in the analysis.
`
`
`
`
` In these pediatric patients receiving 4 mg/kg monthly intramuscular dose of fulvestrant, the geometric
`
` mea
