`
`DOSAGE FORMS AND STRENGTHS
`
`FASLODEX, an injection for intramuscular administration, is
`supplied as 5-mL prefilled syringes containing 50 mg/mL
`fulvestrant.
`
`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.
`
`WARNINGS AND PRECAUTIONS
`
`Blood Disorders
`
`it
`Because FASLODEX is administered intramuscularly,
`should be used with caution in patients with bleeding
`diatheses, thrombocytopenia, or anticoagulant use.
`
`5.2
`
`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)].
`
`Reference ID: 3215285
`
`|nnoPharma Exhibit 1021.0005
`
`
`
`FASLODEX has not been studied in patients with severe
`hepatic impairment (Child-Pugh class C) [see Use in Specific
`Populations (8. 6)].
`
`5.3 Use in Pregnancy
`Based on its mechanism of action and findings in animals,
`FASLODEX can cause fetal harm when administered to a
`
`or
`loss
`fetal
`caused
`Fulvestrant
`pregnant woman.
`abnormalities in animals when administered during the period
`of organogenesis at doses
`significantly smaller
`than the
`maximum recommended human dose based on the body
`surface area. There are no adequate and well-controlled
`studies in pregnant women using FASLODEX. Women of
`childbearing potential
`should be advised not
`to become
`pregnant while receiving FASLODEX.
`If FASLODEX is
`used during pregnancy, or if the patient becomes pregnant
`while receiving this drug, the patient should be apprised of the
`potential hazard to the fetus [see Use in Specific Populations
`(8.1)].

`
`ADVERSE REACTIONS
`
`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.
`
`Comgarison of FASLODEX 500 mg and FASLODEX
`250 mg
`The following frequency categories for adverse reactions
`(ARs) were calculated based on the safety analysis of Study 1
`that compared FASLODEX 500 mg with FASLODEX 250
`mg. 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).

`
`surface area (BSA). Women of childbearing potential should
`be
`advised not
`to become pregnant while
`receiving
`FASLODEX.
`If FASLODEX is used during pregnancy, or if
`the patient becomes pregnant while receiving this drug, the
`patient should be apprised of the potential hazard to the fetus.
`
`In studies in female rats at
`
`intramuscular doses 2 0.01
`
`mg/kg/day (0.6% of the human recommended dose based on
`BSA), fulvestrant caused a reversible reduction in female
`fertility, as well as 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 BSA) and non-ossification of the
`odontoid and ventral tubercle of the first cervical vertebra at
`
`doses 2 0.1 mg/kg/day (6% the human dose based on BSA)
`when administered during the period of organogenesis.
`Rabbits
`failed
`to maintain
`pregnancy when
`dosed
`intramuscularly with 1 mg/kg/day fulvestrant (equivalent to
`the human dose based on BSA) during the period of
`organogenesis. Further,
`in rabbits dosed at 0.25 mg/kg/day
`(30% the human dose based on BSA), increases in placental
`weight and post-implantation loss were observed. 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 BSA) when administered during the period of
`organogenesis. Because pregnancy could not be maintained in
`the rabbit following doses of fulvestrant of 1 mg/kg/day and
`above, this study was inadequate to fully define the possible
`adverse effects on fetal development at clinically relevant
`exposures.
`
`8.3
`
`Nursing Mothers
`It
`is not known if fulvestrant
`
`is excreted in human milk.
`
`Fulvestrant is found in rat milk at levels significantly higher
`(approximately 12-fold) than plasma after administration of 2
`mg/kg. Drug exposure in rodent pups from fulvestrant-treated
`lactating dams was estimated as 10% of the administered
`dose. Because many drugs are excreted in human milk and
`because of the potential
`for serious adverse reactions in
`nursing infants from FASLODEX, a decision should be made
`whether to discontinue nursing or to discontinue the drug,
`taking into account the importance of the drug to the mother.
`
`8.4
`
`Pediatric Use
`
`A multi-center, single-arrn, 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).
`
`Reference ID: 3215285
`
`|nnoPharma Exhibit 1021.0010
`
`
`
`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, -04]); 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, pruritis,
`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 pharrnacokinetic analysis with sparse samples per
`patient obtained from 30 female pediatric patients aged 1 to 8
`years with PPP associated with MAS. Pharrnacokinetic 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 mean (SD)
`CL/F was 444 (165) mL/min which was 32% lower than
`adults. The geometric mean (SD) steady state trough
`concentration (Cmin,ss) and AUCss was 4.19 (0. 87) ng/mL
`and 3680 (1020) ng*hr/mL, respectively.

`Geriatric Use
`
`response was
`For FASLODEX 250 mg, when tumor
`considered by age, objective responses were seen in 22% and
`24% of patients under 65 years of age and in 11% and 16% of
`patients 65 years of age and older, who were treated with
`FASLODEX in Study 2 and Study 3, respectively.
`
`8.6
`
`Hepatic Impairment
`FASLODEX is metabolized primarily in the liver.
`
`The pharmacokinetics of fulvestrant were evaluated after a
`single dose of 100 mg in subjects with mild and moderate
`hepatic impairment and normal hepatic function (n = 7
`subj ects/group), using a shorter-acting intramuscular injection
`formulation. Subjects with mild hepatic impairment (Child-
`Pugh class A) had comparable mean AUC and clearance
`values to those with normal hepatic function. In subjects with
`moderate hepatic impairment
`(Child-Pugh class B)
`the
`average AUC of fulvestrant increased by 70% compared to
`patients with normal hepatic function. AUC was positively
`correlated with total bilirubin concentration (p = 0.012).
`FASLODEX has not been studied in patients with severe
`hepatic impairment (Child-Pugh class C).
`
`A dose of FASLODEX 250 mg is recommended in patients
`with moderate hepatic impainnent (Child-Pugh class B) [see
`Dosage
`and Administration
`(2.2)
`and Warning and
`Precautions (5. 2)].

`
`Renal Impairment
`Negligible amounts of fulvestrant are eliminated in urine;
`therefore, a study in patients with renal impairment was not
`conducted.
`In the advanced breast cancer trials, fulvestrant
`concentrations in women with estimated creatinine clearance
`
`as low as 30 mL/min were similar to women with normal
`
`creatinine.

`
`CLINICAL PHARMACOLOGY
`
`12.1 Mechanism of Action
`
`Many breast cancers have estrogen receptors (ER) and the
`growth of these tumors can be stimulated by estrogen.
`Fulvestrant is an estrogen receptor antagonist that binds to the
`estrogen receptor
`in a competitive manner with affinity
`comparable to that of estradiol and downregulates the ER
`protein in human breast cancer cells.
`
`In vitro studies demonstrated that fulvestrant is a reversible
`
`inhibitor of the growth of tamoxifen-resistant, as well as
`estrogen-sensitive human breast cancer (MCF-7) cell lines.
`In
`in vivo tumor studies, fulvestrant delayed the establishment of
`tumors from xenografts of human breast cancer MCF-7 cells
`in nude mice. Fulvestrant inhibited the growth of established
`MCF-7 xenografts and of tamoxifen-resistant breast tumor
`Xenografts.
`
`in in vivo
`effects
`showed no agonist-type
`Fulvestrant
`uterotropic assays in immature or ovariectomized mice and
`rats.
`In in vivo studies in immature rats and ovariectomized
`
`fulvestrant blocked the uterotrophic action of
`monkeys,
`In postmenopausal women, the absence of changes
`estradiol.
`in plasma concentrations of FSH and LH in response to
`fulvestrant treatment (250 mg monthly) suggests no peripheral
`steroidal effects.
`
`12.2 Pharmacodynamics
`In a clinical study in postmenopausal women with primary
`breast cancer treated with single doses of FASLODEX 15-22
`days prior to surgery, there was evidence of increasing down-
`regulation of ER with increasing dose. This was associated
`with a dose-related decrease in the expression of the
`progesterone receptor, an estrogen-regulated protein. These
`effects on the ER pathway were also associated with a
`decrease in Ki67 labeling index, a marker of cell proliferation.
`
`12.3 Pharmacokinetics
`
`Absorption:
`The single dose and multiple dose PK parameters for the 500
`mg dosing regimen with an additional dose (AD) at Day 15
`are reported in Table 3. The additional dose of FASLODEX
`given two weeks after the initial dose allows for steady state
`concentrations to be reached within the first month of dosing.

`
`Distribution:
`
`steady state is
`The apparent volume of distribution at
`approximately 3 to 5 L/kg. This suggests that distribution is
`largely extravascular. Fulvestrant is highly (99%) bound to
`plasma proteins; VLDL, LDL and HDL lipoprotein fractions
`appear to be the major binding components. The role of sex
`hormone-binding globulin, if any, could not be determined.
`
`Metabolism:
`
`Biotransformation and disposition of fulvestrant in humans
`have
`been
`determined
`following
`intramuscular
`and
`intravenous
`administration
`of MC-labeled
`fulvestrant.
`
`Metabolism of fulvestrant appears to involve combinations of
`a number of possible biotransformation pathways analogous to
`those of endogenous steroids, including oxidation, aromatic
`hydroxylation,
`conjugation with glucuronic
`acid and/or
`sulphate at the 2, 3 and 17 positions of the steroid nucleus, and
`oxidation of the side chain sulphoxide. Identified metabolites
`are either less active or exhibit similar activity to fulvestrant in
`antiestrogen models.
`
`Studies using human liver preparations and recombinant
`human enzymes indicate that cytochrome P-450 3A4 (CYP
`3A4) is the only P-450 isoenzyme involved in the oxidation of
`fulvestrant; however, the relative contribution of P-450 and
`non-P-450 routes in vivo is unknown.
`
`Excretion:
`
`Fulvestrant was rapidly cleared by the hepatobiliary route with
`excretion primarily via the feces (approximately 90%). Renal
`elimination was negligible (less
`than 1%).
`After
`an
`
`intramuscular injection of 250 mg, the clearance (Mean i SD)
`
`was 690 i 226 mL/min with an apparent half-life about 40
`days.

`Geriatric:

`In patients with breast cancer,
`fulvestrant pharmacokinetic profile related to age (range 33 to
`89 years).
`
`Gender:
`
`Following administration of a single intravenous dose, there
`were no pharmacokinetic differences between men and
`women or between premenopausal
`and postmenopausal
`women. Similarly, there were no differences between men
`and
`postmenopausal
`women
`after
`intramuscular
`administration.
`
`Race:
`
`In the advanced breast cancer treatment trials, the potential for
`pharmacokinetic differences due to race have been evaluated
`in 294 women including 87.4% Caucasian, 7.8% Black, and
`4.4% Hispanic. No
`differences
`in
`fulvestrant plasma
`pharmacokinetics were observed among these groups.
`In a
`separate trial, pharmacokinetic data from postmenopausal
`ethnic Japanese women were similar to those obtained in non-
`Japanese patients.
`
`Drug—Drug Interactions:
`There are no known drug-drug interactions. Fulvestrant does
`not significantly inhibit any of the major CYP isoenzymes,
`including CYP 1A2, 2C9, 2Cl9, 2D6, and 3A4 in vitro, and
`studies of co-administration of fulvestrant with midazolam

`inhibitory effects on CYP 3A4 or alter blood levels of drug
`metabolized by that enzyme. Although fulvestrant is partly
`metabolized by CYP 3A4, a clinical study with rifampin, an
`inducer
`of CYP 3A4,
`showed
`no
`effect
`on
`the
`pharmacokinetics of fulvestrant. Also results from a healthy
`volunteer
`study with ketoconazole, a potent
`inhibitor of
`CYP3A4,
`indicated that ketoconazole had no effect on the
`pharmacokinetics of fulvestrant and dosage adjustment is not
`necessary in patients co-prescribed CYP3A4 inhibitors or
`inducers [see Drug Interactions (7)].

`
`NONCLINICAL TOXICOLOGY
`
`13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
`Two-year carcinogenesis studies were conducted in rats and
`mice. Positive findings were observed in both species. Rats
`were treated at intramuscular doses of 15 mg/kg/30 days, 10
`mg/rat/30 days and 10 mg/rat/l5 days.
`
`These doses correspond to 0.9-, 1.5-, and 3-fold (in females)
`and 0.8-, 0.8-, and 2-fold (in males) the systemic exposure

`
`|nnoPharma Exhibit 1021.0016
`
`
`
`[AUC0_30 days] achieved in women receiving the recommended
`dose of 500 mg/month. An increased incidence of benign
`ovarian granulosa cell
`tumors and testicular Leydig cell
`tumors was evident, in females dosed at 10 mg/rat/ 15 days and
`males dosed at 15 mg/rat/30 days, respectively. Mice were
`treated at oral doses of 0, 20, 150 and 500 mg/kg/day. These
`doses correspond to 0.8-, 8.4- and 18-fold (in females) and
`0.8-, 7.1- and 11.9- fold (in males), the systemic exposure
`[AUC0_30 days] achieved in women receiving the recommended
`dose of 500 mg/month. There was an increased incidence of
`sex cord stromal tumors (both benign and malignant) in the
`ovary of mice at doses of 150 and 500 mg/kg/day. Induction
`of such tumors is consistent with the pharmacology-related
`endocrine feedback alterations in gonadotropin levels caused
`by an antiestrogen.
`
`Fulvestrant was not mutagenic or clastogenic in multiple
`in vitro tests with and without the addition of a mammali
