Faslodex is indicated:

* as monotherapy for the treatment of estrogen receptor positive, locally advanced or metastaticbreast cancer in postmenopausal women:

- not previously treated with endocrine therapy, or

- with disease relapse on or after adjuvant antiestrogen therapy, or disease progression onantiestrogen therapy.

* in combination with palbociclib for the treatment of hormone receptor (HR)-positive, humanepidermal growth factor receptor 2 (HER2)-negative locally advanced or metastatic breastcancer in women who have received prior endocrine therapy (see section 5.1).

In pre- or perimenopausal women, the combination treatment with palbociclib should be combinedwith a luteinizing hormone releasing hormone (LHRH) agonist.

Adult females (including Elderly)

The recommended dose is 500 mg at intervals of one month, with an additional 500 mg dose giventwo weeks after the initial dose.

When Faslodex is used in combination with palbociclib, please also refer to the Summary of Product

Characteristics of palbociclib.

Prior to the start of treatment with the combination of Faslodex plus palbociclib, and throughout itsduration, pre/perimenopausal women should be treated with LHRH agonists according to local clinicalpractice.

No dose adjustments are recommended for patients with mild to moderate renal impairment (creatinineclearance 30 ml/min). Safety and efficacy have not been evaluated in patients with severe renalimpairment (creatinine clearance <30 ml/min), and, therefore, caution is recommended in thesepatients (see section 4.4).

No dose adjustments are recommended for patients with mild to moderate hepatic impairment.

However, as fulvestrant exposure may be increased, Faslodex should be used with caution in thesepatients. There are no data in patients with severe hepatic impairment (see sections pct. 4.3, pct. 4.4 and 5.2).

The safety and efficacy of Faslodex in children from birth to 18 years of age have not beenestablished. Currently available data are described in sections 5.1 and 5.2, but no recommendation on aposology can be made.

Faslodex should be administered as two consecutive 5 ml injections by slow intramuscular injection(1-2 minutes/injection), one in each buttock (gluteal area).

Caution should be taken if injecting Faslodex at the dorsogluteal site due to the proximity of theunderlying sciatic nerve.

For detailed instructions for administration, see section 6.6.

Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.

Pregnancy and lactation (see section 4.6).

Severe hepatic impairment (see sections 4.4 and 5.2).

Faslodex should be used with caution in patients with mild to moderate hepatic impairment (seesections 4.2, pct. 4.3 and 5.2).

Faslodex should be used with caution in patients with severe renal impairment (creatinine clearanceless than 30 ml/min).

Due to the intramuscular route of administration, Faslodex should be used with caution if treatingpatients with bleeding diatheses, thrombocytopenia or those taking anticoagulant treatment.

Thromboembolic events are commonly observed in women with advanced breast cancer and havebeen observed in clinical studies with Faslodex (see section 4.8). This should be taken intoconsideration when prescribing Faslodex to patients at risk.

Injection site related events including sciatica, neuralgia, neuropathic pain, and peripheral neuropathyhave been reported with Faslodex injection. Caution should be taken while administering Faslodex atthe dorsogluteal injection site due to the proximity of the underlying sciatic nerve (see sections 4.2 and4.8).

There are no long-term data on the effect of fulvestrant on bone. Due to the mechanism of action offulvestrant, there is a potential risk of osteoporosis.

The efficacy and safety of Faslodex (either as monotherapy or in combination with palbociclib) havenot been studied in patients with critical visceral disease.

When Faslodex is combined with palbociclib, please also refer to the Summary of Product

Characteristics of palbociclib.

Interference with estradiol antibody assays

Due to the structural similarity of fulvestrant and estradiol, fulvestrant may interfere with antibodybased-estradiol assays and may result in falsely increased levels of estradiol.

Faslodex contains 10% w/v ethanol (alcohol) as an excipient, i.e. up to 500 mg per injection,equivalent to 12 ml beer or 5 ml wine. This may be harmful for those suffering from alcoholism andshould be taken into account in high risk groups such as patients with liver disease and epilepsy.

Benzyl alcohol

Faslodex contains benzyl alcohol as an excipient which may cause allergic reactions.

Faslodex is not recommended for use in children and adolescents as safety and efficacy have not beenestablished in this group of patients (see section 5.1).

A clinical interaction study with midazolam (substrate of CYP3A4) demonstrated that fulvestrant doesnot inhibit CYP3A4. Clinical interaction studies with rifampicin (inducer of CYP3A4) andketoconazole (inhibitor of CYP3A4) showed no clinically relevant change in fulvestrant clearance.

Dose adjustment is therefore not necessary in patients who are receiving fulvestrant and CYP3A4inhibitors or inducers concomitantly.

Patients of childbearing potential should use effective contraception during treatment with Faslodexand for 2 years after the last dose.

Faslodex is contraindicated in pregnancy (see section 4.3). Fulvestrant has been shown to cross theplacenta after single intramuscular doses in rat and rabbit. Studies in animals have shown reproductivetoxicity including an increased incidence of foetal abnormalities and deaths (see section 5.3). Ifpregnancy occurs while taking Faslodex, the patient must be informed of the potential hazard to thefoetus and potential risk for loss of pregnancy.

Breast-feeding must be discontinued during treatment with Faslodex. Fulvestrant is excreted in milk inlactating rats. It is not known whether fulvestrant is excreted in human milk. Considering the potentialfor serious adverse reactions due to fulvestrant in breast-fed infants, use during lactation iscontraindicated (see section 4.3).

The effects of Faslodex on fertility in humans has not been studied.

Faslodex has no or negligible influence on the ability to drive or use machines. However, sinceasthenia has been reported very commonly with Faslodex, caution should be observed by thosepatients who experience this adverse reaction when driving or operating machinery.

This section provides information based on all adverse reactions from clinical studies, post-marketingstudies or spontaneous reports. In the pooled dataset of fulvestrant monotherapy, the most frequentlyreported adverse reactions were injection site reactions, asthenia, nausea, and increased hepaticenzymes (ALT, AST, ALP).

In Table 1, the following frequency categories for adverse drug reactions (ADRs) were calculatedbased on the Faslodex 500 mg treatment group in pooled safety analyses of studies that compared

Faslodex 500 mg with Faslodex 250 mg [CONFIRM (Study D6997C00002), FINDER 1 (Study

D6997C00004), FINDER 2 (Study D6997C00006), and NEWEST (Study D6997C00003) studies], orfrom FALCON (Study D699BC00001) alone that compared Faslodex 500 mg with anastrozole 1 mg.

Where frequencies differ between the pooled safety analysis and FALCON, the highest frequency ispresented. The frequencies in Table 1 were based on all reported adverse drug reactions, regardless ofthe investigator assessment of causality. The median duration of fulvestrant 500 mg treatment acrossthe pooled dataset (including the studies mentioned above plus FALCON) was 6.5 months.

Adverse reactions listed below are classified according to frequency and System Organ Class (SOC).

Frequency groupings are defined according to the following convention: Very common (≥1/10),

Common (≥1/100 to <1/10), Uncommon (≥1/1,000 to <1/100). Within each frequency groupingadverse reactions are reported in order of decreasing seriousness.

Thefrequency has been calculated using the upper limit of the 95% confidence interval for the point estimate.

This is calculated as 3/560 (where 560 is the number of patients in the major clinical studies), whichequates to a frequency category of ‘uncommon’.d Includes: arthralgia, and less frequently musculoskeletal pain, myalgia and pain in extremity.e Frequency category differs between pooled safety dataset and FALCON.f ADR was not observed in FALCON.

The descriptions included below are based on the safety analysis set of 228 patients who received atleast one (1) dose of fulvestrant and 232 patients who received at least one (1) dose of anastrozole,respectively in the Phase 3 FALCON study.

Joint and musculoskeletal pain

In the FALCON study, the number of patients who reported an adverse reaction of joint andmusculoskeletal pain was 65 (31.2%) and 48 (24.1%) for fulvestrant and anastrozole arms,respectively. Of the 65 patients in the Faslodex arm, 40% (26/65) of patients reported joint andmusculoskeletal pain within the first month of treatment, and 66.2% (43/65) of patients within the first3 months of treatment. No patients reported events that were CTCAE Grade ≥3 or that required a dosereduction, dose interruption, or discontinued treatment due to these adverse reactions.

Combination therapy with palbociclib

The overall safety profile of fulvestrant when used in combination with palbociclib is based on datafrom 517 patients with HR-positive, HER2-negative advanced or metastatic breast cancer in therandomised PALOMA3 study (see section 5.1). The most common (≥20%) adverse reactions of anygrade reported in patients receiving fulvestrant in combination with palbociclib were neutropenia,leukopenia, infections, fatigue, nausea, anaemia, stomatitis, diarrhoea, thrombocytopenia andvomiting. The most common (≥2%) Grade ≥3 adverse reactions were neutropenia, leukopenia,infections, anaemia, AST increased, thrombocytopenia, and fatigue.

Table 2 reports the adverse reactions from PALOMA3.

Median duration of exposure to fulvestrant was 11.2 months in the fulvestrant + palbociclib arm and4.8 months in the fulvestrant + placebo arm. Median duration of exposure to palbociclib in thefulvestrant + palbociclib arm was 10.8 months.

In patients receiving fulvestrant in combination with palbociclib in the PALOMA3 study, neutropeniaof any grade was reported in 290 (84.1%) patients, with Grade 3 neutropenia being reported in 200(58.0%) patients, and Grade 4 neutropenia being reported in 40 (11.6%) patients. In the fulvestrant +placebo arm (n=172), neutropenia of any grade was reported in 6 (3.5%) patients. There were noreports of Grade 3 and 4 neutropenia in the fulvestrant + placebo arm.

In patients receiving fulvestrant in combination with palbociclib, the median time to first episode ofany grade neutropenia was 15 days (range: 13-512 days) and the median duration of Grade ≥3neutropenia was 16 days. Febrile neutropenia has been reported in 3 (0.9%) patients receivingfulvestrant in combination with palbociclib.

Reporting suspected adverse reactions after authorisation of the medicinal product is important. Itallows continued monitoring of the benefit/risk balance of the medicinal product. Healthcareprofessionals are asked to report any suspected adverse reactions via the national reporting systemlisted in Appendix V.

There are isolated reports of overdose with Faslodex in humans. If overdose occurs, symptomaticsupportive treatment is recommended. Animal studies suggest that no effects other than those relateddirectly or indirectly to antiestrogenic activity were evident with higher doses of fulvestrant (seesection 5.3).

Pharmacotherapeutic group: Endocrine therapy, Antiestrogens, ATC code: L02BA03

Mechanism of action and pharmacodynamic effects

Fulvestrant is a competitive estrogen receptor (ER) antagonist with an affinity comparable to estradiol.

Fulvestrant blocks the trophic actions of estrogens without any partial agonist (estrogen-like) activity.

The mechanism of action is associated with downregulation of estrogen receptor protein levels.

Clinical studies in postmenopausal women with primary breast cancer have shown that fulvestrantsignificantly downregulates ER protein in ER positive tumours compared with placebo. There was alsoa significant decrease in progesterone receptor expression consistent with a lack of intrinsic estrogenagonist effects. It has also been shown that fulvestrant 500 mg downregulates ER and the proliferationmarker Ki67, to a greater degree than fulvestrant 250 mg in breast tumours in postmenopausalneoadjuvant setting.

Clinical efficacy and safety in advanced breast cancer

A Phase 3 clinical study was completed in 736 postmenopausal women with advanced breast cancerwho had disease recurrence on or after adjuvant endocrine therapy or progression following endocrinetherapy for advanced disease. The study included 423 patients whose disease had recurred orprogressed during antiestrogen therapy (AE subgroup) and 313 patients whose disease had recurred orprogressed during aromatase inhibitor therapy (AI subgroup). This study compared the efficacy andsafety of Faslodex 500 mg (n=362) with Faslodex 250 mg (n=374). Progression-free survival (PFS)was the primary endpoint; key secondary efficacy endpoints included objective response rate (ORR),clinical benefit rate (CBR) and overall survival (OS). Efficacy results for the CONFIRM study aresummarized in Table 3.

A Phase 3, randomised, double-blind, double-dummy, multicentre study of Faslodex 500 mg versusanastrozole 1 mg was conducted in postmenopausal women with ER-positive and/or PgR-positivelocally advanced or metastatic breast cancer who had not previously been treated with any hormonaltherapy. A total of 462 patients were randomised 1:1 sequentially to receive either fulvestrant 500 mgor anastrozole 1 mg. Randomisation was stratified by disease setting (locally advanced or metastatic),prior chemotherapy for advanced disease, and measurable disease.

The primary efficacy endpoint of the study was investigator assessed progression-free survival (PFS)evaluated according to RECIST 1.1 (Response Evaluation Criteria in Solid Tumours). Key secondaryefficacy endpoints included overall survival (OS) and objective response rate (ORR).

Patients enrolled in this study had a median age of 63 years (range 36-90). The majority of patients(87.0%) had metastatic disease at baseline. Fifty-five percent (55.0%) of patients had visceralmetastasis at baseline. A total of 17.1% of patients received a prior chemotherapy regimen foradvanced disease; 84.2% of patients had measurable disease.

Consistent results were observed across the majority of pre-specified patient subgroups. For thesubgroup of patients with disease limited to non-visceral metastasis (n=208), the HR was 0.592 (95%

CI: 0.419, 0.837) for the Faslodex arm compared to the anastrozole arm. For the subgroup of patientswith visceral metastasis (n=254), the HR was 0.993 (95% CI: 0.740, 1.331) for the Faslodex armcompared to the anastrozole arm. The efficacy results of the FALCON study are presented in Table 4and Figure 1.

Two Phase 3 clinical studies were completed in a total of 851 postmenopausal women with advancedbreast cancer who had disease recurrence on or after adjuvant endocrine therapy or progressionfollowing endocrine therapy for advanced disease. Seventy seven percent (77%) of the studypopulation had estrogen receptor positive breast cancer. These studies compared the safety andefficacy of monthly administration of Faslodex 250 mg versus the daily administration of 1 mganastrozole (aromatase inhibitor). Overall, Faslodex at the 250 mg monthly dose was at least aseffective as anastrozole in terms of progression-free survival, objective response, and time to death.

There were no statistically significant differences in any of these endpoints between the two treatmentgroups. Progression-free survival was the primary endpoint. Combined analysis of both studiesshowed that 83% of patients who received Faslodex progressed, compared with 85% of patients whoreceived anastrozole. Combined analysis of both studies showed the hazard ratio of Faslodex 250 mgto anastrozole for progression-free survival was 0.95 (95% CI 0.82 to 1.10). The objective responserate for Faslodex 250 mg was 19.2% compared with 16.5% for anastrozole. The median time to deathwas 27.4 months for patients treated with Faslodex and 27.6 months for patients treated withanastrozole. The hazard ratio of Faslodex 250 mg to anastrozole for time to death was 1.01 (95% CI0.86 to 1.19).

Combination therapy with palbociclib

A Phase 3, international, randomised, double-blind, parallel-group, multicentre study of Faslodex500 mg plus palbociclib 125 mg versus Faslodex 500 mg plus placebo was conducted in women with

HR-positive, HER2-negative locally advanced breast cancer not amenable to resection or radiationtherapy with curative intent or metastatic breast cancer, regardless of their menopausal status, whosedisease progressed after prior endocrine therapy in the (neo) adjuvant or metastatic setting.

A total of 521 pre/peri- and postmenopausal women who had progressed on or within 12 months fromcompletion of adjuvant endocrine therapy on or within 1 month from prior endocrine therapy foradvanced disease, were randomised 2:1 to Faslodex plus palbociclib or Faslodex plus placebo andstratified by documented sensitivity to prior hormonal therapy, menopausal status at study entry(pre/peri- versus postmenopausal), and presence of visceral metastases. Pre/perimenopausal womenreceived the LHRH agonist goserelin. Patients with advanced/metastatic, symptomatic, visceralspread, that were at risk of life-threatening complications in the short term (including patients with

Probability of PFSmassive uncontrolled effusions [pleural, pericardial, peritoneal], pulmonary lymphangitis, and over50% liver involvement), were not eligible for enrolment into the study.

Patients continued to receive assigned treatment until objective disease progression, symptomaticdeterioration, unacceptable toxicity, death, or withdrawal of consent, whichever occurred first.

Crossover between treatment arms was not allowed.

Patients were well matched for baseline demographics and prognostic characteristics between the

Faslodex plus palbociclib arm and the Faslodex plus placebo arm. The median age of patients enrolledin this study was 57 years (range 29, 88). In each treatment arm the majority of patients were

White, had documented sensitivity to prior hormonal therapy, and were postmenopausal.

Approximately 20% of patients were pre/perimenopausal. All patients had received prior systemictherapy and most patients in each treatment arm had received a previous chemotherapy regimen fortheir primary diagnosis. More than half (62%) had an ECOG PS of 0, 60% had visceral metastases,and 60% had received more than 1 prior hormonal regimen for their primary diagnosis.

The primary endpoint of the study was investigator-assessed PFS evaluated according to RECIST 1.1.

Supportive PFS analyses were based on an Independent Central Radiology Review. Secondaryendpoints included OR, CBR, overall survival (OS), safety, and time-to-deterioration (TTD) in painendpoint.

The study met its primary endpoint of prolonging investigator-assessed PFS at the interim analysisconducted on 82% of the planned PFS events; the results crossed the pre-specified Haybittle-Petoefficacy boundary (α=0.00135), demonstrating a statistically significant prolongation in PFS and aclinically meaningful treatment effect. A more mature update of efficacy data is reported in Table 5.

After a median follow-up time of 45 months, the final OS analysis was performed based on 310 events(60% of randomised patients). A 6.9-month difference in median OS in the palbociclib plus fulvestrantarm compared with the placebo plus fulvestrant arm was observed; this result was not statisticallysignificant at the prespecified significance level of 0.0235 (1-sided). In the placebo plus fulvestrantarm, 15.5% of randomised patients received palbociclib and other CDK inhibitors as post-progressionsubsequent treatments.

The results from the investigator-assessed PFS and final OS data from PALOMA3 study are presentedin Table 5. The relevant Kaplan-Meier plots are shown in Figures 2 and 3, respectively.

Patient-reported symptoms were assessed using the European Organization for Research and

Treatment of Cancer (EORTC) quality of life questionnaire (QLQ)-C30 and its Breast Cancer Module(EORTC QLQ-BR23). A total of 335 patients in the Faslodex plus palbociclib arm and 166 patients inthe Faslodex plus placebo arm completed the questionnaire at baseline and at least 1 post-baselinevisit.

Time-to-Deterioration was pre-specified as time between baseline and first occurrence of ≥10 pointsincrease from baseline in pain symptom scores. Addition of palbociclib to Faslodex resulted in asymptom benefit by significantly delaying Time-to-Deterioration in pain symptom compared with

Faslodex plus placebo (median 8.0 months versus 2.8 months; HR of 0.64 [95% CI: 0.49, 0.85];p<0.001).

Effects on the postmenopausal endometrium

Preclinical data do not suggest a stimulatory effect of fulvestrant on the postmenopausal endometrium(see section 5.3). A 2-week study in healthy postmenopausal volunteers treated with 20 μg per day

Overall Survival Probability (%)ethinylestradiol showed that pretreatment with Faslodex 250 mg resulted in significantly reducedstimulation of the postmenopausal endometrium, compared to pre-treatment with placebo, as judgedby ultrasound measurement of endometrium thickness.

Neoadjuvant treatment for up to 16 weeks in breast cancer patients treated with either Faslodex500 mg or Faslodex 250 mg did not result in clinically significant changes in endometrial thickness,indicating a lack of agonist effect. There is no evidence of adverse endometrial effects in the breastcancer patients studied. No data are available regarding endometrial morphology.

In two short-term studies (1 and 12 weeks) in premenopausal patients with benign gynaecologicdisease, no significant differences in endometrial thickness were observed by ultrasound measurementbetween fulvestrant and placebo groups.

Effects on bone

There are no long-term data on the effect of fulvestrant on bone. Neoadjuvant treatment for up to16 weeks in breast cancer patients with either Faslodex 500 mg or Faslodex 250 mg did not result inclinically significant changes in serum bone-turnover markers.

Faslodex is not indicated for use in children. The European Medicines Agency has waived theobligation to submit the results of studies with Faslodex in all subsets of the paediatric population inbreast cancer (see section 4.2 for information on paediatric use).

An open-label Phase 2 study investigated the safety, efficacy and pharmacokinetics of fulvestrant in30 girls aged 1 to 8 years with Progressive Precocious Puberty associated with McCune Albright

Syndrome (MAS). The paediatric patients received 4 mg/kg monthly intramuscular dose of fulvestrant.

This 12-month study investigated a range of MAS endpoints and showed a reduction in the frequencyof vaginal bleeding and a reduction in the rate of bone age advancement. The steady-state troughconcentrations of fulvestrant in children in this study were consistent with that in adults (seesection 5.2). There were no new safety concerns arising from this small study, but 5-year data are yetnot available.

After administration of Faslodex long-acting intramuscular injection, fulvestrant is slowly absorbedand maximum plasma concentrations (Cmax) are reached after about 5 days. Administration of

Faslodex 500 mg regimen achieves exposure levels at, or close to, steady state within the first monthof dosing (mean [CV]: AUC 475 [33.4%] ng.days/ml, Cmax 25.1 [35.3%] ng/ml, Cmin16.3 [25.9%] ng/ml, respectively). At steady state, fulvestrant plasma concentrations are maintainedwithin a relatively narrow range with up to an approximately 3-fold difference between maximum andtrough concentrations. After intramuscular administration, the exposure is approximatelydose-proportional in the dose range 50 to 500 mg.

Fulvestrant is subject to extensive and rapid distribution. The large apparent volume of distribution atsteady state (Vdss) of approximately 3 to 5 l/kg suggests that distribution is largely extravascular.

Fulvestrant is highly (99%) bound to plasma proteins. Very low density lipoprotein (VLDL), lowdensity lipoprotein (LDL), and high density lipoprotein (HDL) fractions are the major bindingcomponents. No interaction studies were conducted on competitive protein binding. The role of sexhormone-binding globulin (SHBG) has not been determined.

The metabolism of fulvestrant has not been fully evaluated, but involves combinations of a number ofpossible biotransformation pathways analogous to those of endogenous steroids. Identified metabolites(includes 17-ketone, sulphone, 3-sulphate, 3- and 17-glucuronide metabolites) are either less active orexhibit similar activity to fulvestrant in antiestrogen models. Studies using human liver preparationsand recombinant human enzymes indicate that CYP3A4 is the only P450 isoenzyme involved in theoxidation of fulvestrant; however, non-P450 routes appear to be more predominant in vivo. In vitrodata suggest that fulvestrant does not inhibit CYP450 isoenzymes.

Fulvestrant is eliminated mainly in metabolised form. The major route of excretion is via the faeces,with less than 1% being excreted in the urine. Fulvestrant has a high clearance, 11±1.7 ml/min/kg,suggesting a high hepatic extraction ratio. The terminal half-life (t1/2) after intramuscularadministration is governed by the absorption rate and was estimated to be 50 days.

In a population pharmacokinetic analysis of data from Phase 3 studies, no difference in fulvestrant’spharmacokinetic profile was detected with regard to age (range 33 to 89 years), weight (40-127 kg) orrace.

Mild to moderate impairment of renal function did not influence the pharmacokinetics of fulvestrant toany clinically relevant extent.

The pharmacokinetics of fulvestrant has been evaluated in a single-dose clinical study conducted inwomen with mild to moderate hepatic impairment (Child-Pugh class A and B). A high dose of ashorter duration intramuscular injection formulation was used. There was up to about 2.5-fold increasein AUC in women with hepatic impairment compared to healthy subjects. In patients administered

Faslodex, an increase in exposure of this magnitude is expected to be well tolerated. Women withsevere hepatic impairment (Child-Pugh class C) were not evaluated.

The pharmacokinetics of fulvestrant has been evaluated in a clinical study conducted in 30 girls with

Progressive Precocious Puberty associated with McCune Albright Syndrome (see section 5.1). Thepaediatric patients were aged 1 to 8 years and received 4 mg/kg monthly intramuscular dose offulvestrant. The geometric mean (standard deviation) steady state trough concentration (Cmin,ss) and

AUCss was 4.2 (0.9) ng/mL and 3680 (1020) ng*hr/mL, respectively. Although the data collected werelimited, the steady-state trough concentrations of fulvestrant in children appear to be consistent withthose in adults.

The acute toxicity of fulvestrant is low.

Faslodex and other formulations of fulvestrant were well tolerated in animal species used in multipledose studies. Local reactions, including myositis and granulomata at the injection site were attributedto the vehicle but the severity of myositis in rabbits increased with fulvestrant, compared to the salinecontrol. In toxicity studies with multiple intramuscular doses of fulvestrant in rats and dogs, theantiestrogenic activity of fulvestrant was responsible for most of the effects seen, particularly in thefemale reproductive system, but also in other organs sensitive to hormones in both sexes. Arteritisinvolving a range of different tissues was seen in some dogs after chronic (12 months) dosing.

In dog studies following oral and intravenous administration, effects on the cardiovascular system(slight elevations of the S-T segment of the ECG [oral], and sinus arrest in one dog [intravenous])were seen. These occurred at exposure levels higher than in patients (Cmax >15 times) and are likely tobe of limited significance for human safety at the clinical dose.

Fulvestrant showed no genotoxic potential.

Fulvestrant showed effects upon reproduction and embryo/foetal development consistent with itsantiestrogenic activity, at doses similar to the clinical dose. In rats, a reversible reduction in femalefertility and embryonic survival, dystocia and an increased incidence of foetal abnormalities includingtarsal flexure were observed. Rabbits given fulvestrant failed to maintain pregnancy. Increases inplacental weight and post-implantation loss of foetuses were seen. There was an increased incidence offoetal variations in rabbits (backwards displacement of the pelvic girdle and 27 pre-sacral vertebrae).

A two-year oncogenicity study in rats (intramuscular administration of Faslodex) showed increasedincidence of ovarian benign granulosa cell tumours in female rats at the high dose, 10 mg/rat/15 daysand an increased incidence of testicular Leydig cell tumours in males. In a two-year mouseoncogenicity study (daily oral administration) there was an increased incidence of ovarian sex cordstromal tumours (both benign and malignant) at doses of 150 and 500 mg/kg/day. At the no-effectlevel for these findings, systemic exposure levels (AUC) were, in rats, approximately 1.5-fold theexpected human exposure levels in females and 0.8-fold in males, and in mice, approximately 0.8-foldthe expected human exposure levels in both males and females. Induction of such tumours isconsistent with pharmacology-related endocrine feedback alterations in gonadotropin levels caused byantiestrogens in cycling animals. Therefore, these findings are not considered to be relevant to the useof fulvestrant in postmenopausal women with advanced breast cancer.

Environmental risk assessment studies have shown that fulvestrant may have potential to causeadverse effects to the aquatic environment (see section 6.6).
