  • BOXED WARNING (What is this?)

    WARNING: ENDOMETRIAL CANCER and CARDIOVASCULAR DISORDERS

    Endometrial Cancer

    OSPHENA is an estrogen agonist/antagonist with tissue selective effects. In the endometrium, OSPHENA has estrogen agonistic effects. There is a potential increased risk of endometrial cancer in a woman with a uterus who uses unopposed estrogens. Adequate diagnostic measures, including directed and random endometrial sampling when indicated, should be undertaken to rule out malignancy in postmenopausal women with undiagnosed persistent or recurring abnormal genital bleeding [see Warnings and Precautions (5.2)].

    Cardiovascular Disorders

    In the clinical trials for OSPHENA (duration of treatment up to 15 months), the incidence rates of thromboembolic and hemorrhagic stroke were 1.13 and 3.39 per thousand women years, respectively in the OSPHENA 60 mg treatment group and 3.15 and 0 with placebo [see Warnings and Precautions (5.1)]. The incidence of DVT was 2.26 per thousand women years (2 reported cases) in the OSPHENA 60 mg treatment group and 3.15 per thousand women years (1 reported case) with placebo [see Warnings and Precautions (5.1)]. OSPHENA should be prescribed for the shortest duration consistent with treatment goals and risks for the individual woman.

    There is a reported increased risk of stroke and deep vein thrombosis (DVT) in postmenopausal women (50 to 79 years of age) who received daily oral conjugated estrogens (CE) [0.625 mg]-alone therapy over 7.1 years as part of the Women's Health Initiative (WHI) [see Warnings and Precautions (5.1)].

  • 1 INDICATIONS AND USAGE

    OSPHENA is indicated for:

    1.1 The Treatment of Moderate to Severe Dyspareunia, a Symptom of Vulvar and Vaginal Atrophy, Due to Menopause.

    1.2 The Treatment of Moderate to Severe Vaginal Dryness, a Symptom of Vulvar and Vaginal Atrophy, Due to Menopause.

  • 2 DOSAGE AND ADMINISTRATION

    OSPHENA is an estrogen agonist/antagonist which has agonistic effects on the endometrium [see Warnings and Precautions (5.2)].

    Use of OSPHENA should be for the shortest duration consistent with treatment goals and risks for the individual woman. Postmenopausal women should be re-evaluated periodically as clinically appropriate to determine if treatment is still necessary.

    2.1 Treatment of Moderate to Severe Dyspareunia, a Symptom of Vulvar and Vaginal Atrophy, Due to Menopause

    Take one 60 mg tablet with food once daily.

    2.2 Treatment of Moderate to Severe Vaginal Dryness, a Symptom of Vulvar and Vaginal Atrophy, Due to Menopause

    Take one 60 mg tablet with food once daily.

  • 3 DOSAGE FORMS AND STRENGTHS

    OSPHENA tablets are white to off-white, oval, biconvex, film coated tablets containing 60 mg of ospemifene and engraved with "60" on one side.

  • 4 CONTRAINDICATIONS

    OSPHENA is contraindicated in women with any of the following conditions:

    • Undiagnosed abnormal genital bleeding.
    • Known or suspected estrogen-dependent neoplasia.
    • Active DVT, pulmonary embolism (PE), or a history of these conditions.
    • Active arterial thromboembolic disease [for example, stroke and myocardial infarction (MI)], or a history of these conditions.
    • Hypersensitivity (for example, angioedema, urticaria, rash, pruritus) to OSPHENA or any ingredients.
    • OSPHENA is contraindicated in women who are or may become pregnant. OSPHENA may cause fetal harm when administered to a pregnant woman. Ospemifene was embryo-fetal lethal with labor difficulties and increased pup deaths in rats at doses below clinical exposures, and embryo-fetal lethal in rabbits at 10 times the clinical exposure based on mg/m2. If this drug is used during pregnancy, or if a woman becomes pregnant while taking this drug, she should be apprised of the potential hazard to a fetus.
  • 5 WARNINGS AND PRECAUTIONS

    5.1 Cardiovascular Disorders

    Risk factors for cardiovascular disorders, arterial vascular disease (for example, hypertension, diabetes mellitus, tobacco use, hypercholesterolemia, and obesity) and/or venous thromboembolism (VTE) (for example, personal history or family history of VTE, obesity, and systemic lupus erythematosus) should be managed appropriately.

    Stroke

    In the clinical trials for OSPHENA (duration of treatment up to 15 months), the incidence rates of thromboembolic and hemorrhagic stroke were 1.13 and 3.39 per thousand women years, respectively in OSPHENA 60 mg treatment group and 3.15 and 0 per thousand women years in placebo.

    Should thromboembolic or hemorrhagic stroke occur or be suspected, OSPHENA should be discontinued immediately.

    In the WHI estrogen-alone substudy, a statistically significant increased risk of stroke was reported in women 50 to 79 years of age receiving daily CE (0.625 mg)-alone compared to women in the same age group receiving placebo (45 versus 33 per ten thousand women years). The increase in risk was demonstrated in year 1 and persisted.

    Coronary Heart Disease

    In the OSPHENA clinical trials, two cases of myocardial infarction (MI) occurred in women receiving 60 mg of ospemifene.

    In the WHI estrogen-alone substudy, no overall effect on coronary heart disease (CHD) events (defined as nonfatal MI, silent MI, or CHD death) was reported in women receiving estrogen-alone compared to placebo.

    Venous Thromboembolism

    In the OSPHENA clinical trials, two cases of DVT occurred in women receiving OSPHENA 60 mg. Should a VTE occur or be suspected, OSPHENA should be discontinued immediately.

    If feasible, OSPHENA should be discontinued at least 4 to 6 weeks before surgery of the type associated with an increased risk of thromboembolism, or during periods of prolonged immobilization.

    In the WHI estrogen-alone substudy, the risk of VTE (DVT and PE) was increased for women receiving daily CE (0.625 mg)-alone compared to placebo (30 versus 22 per ten thousand women years), although only the increased risk of DVT reached statistical significance (23 versus 15 per ten thousand women years). The increase in VTE risk was demonstrated during the first 2 years.

    5.2 Malignant Neoplasms

    Endometrial Cancer

    OSPHENA is an estrogen agonist/antagonist with tissue selective effects. In the endometrium, OSPHENA has agonistic effects. In the OSPHENA clinical trials (60 mg treatment group), no cases of endometrial cancer were seen with exposure up to 52 weeks. There was a single case of simple hyperplasia without atypia. Endometrial thickening equal to 5 mm or greater was seen in the OSPHENA up to 52 weeks treatment groups at a rate of 101.4 per thousand women vs. 20.9 per thousand women for placebo. The incidence of any type of proliferative (weakly plus active plus disordered) endometrium was 26.3 per thousand women in the OSPHENA up to 52 weeks treatment groups vs. 0 per thousand women for placebo. Uterine polyps occurred at an incidence of 19.6 per thousand women in the OSPHENA up to 52 weeks treatment groups vs. 8.3 per thousand women for placebo.

    An increased risk of endometrial cancer has been reported with the use of unopposed estrogen therapy in a woman with a uterus. The reported endometrial cancer risk among unopposed estrogen users is about 2 to 12 times greater than in non-users, and appears dependent on duration of treatment and on estrogen dose. Most studies show no significant increased risk associated with the use of estrogens for less than 1 year. The greatest risk appears to be associated with prolonged use, with increased risks of 15- to 24-fold for 5 to 10 years or more. This risk has been shown to persist for at least 8 to 15 years after estrogen therapy is discontinued. Adding a progestin to postmenopausal estrogen therapy has been shown to reduce the risk of endometrial hyperplasia, which may be a precursor to endometrial cancer. There are, however, possible risks that may be associated with the use of progestins with estrogens compared to estrogen-alone regimens. These include an increased risk of breast cancer. The use of progestins with OSPHENA therapy was not evaluated in the clinical trials.

    Clinical surveillance of all women using OSPHENA is important. Adequate diagnostic measures, including directed or random endometrial sampling when indicated, should be undertaken to rule out malignancy in postmenopausal women with undiagnosed persistent or recurring abnormal genital bleeding.

    Breast Cancer

    OSPHENA 60 mg has not been adequately studied in women with breast cancer; therefore, it should not be used in women with known or suspected breast cancer.

    The Women’s Health Initiative (WHI) substudy of daily conjugated estrogen (CE) (0.625 mg)-alone provided information about breast cancer in estrogen-alone users. In the WHI estrogen alone substudy, after an average follow-up of 7.1 years, daily CE alone was not associated with an increased risk of invasive breast cancer [relative risk (RR) 0.80] compared to placebo.

    After a mean follow-up of 5.6 years, the WHI substudy of daily CE (0.625 mg) plus medroxyprogesterone acetate (MPA) (2.5 mg) reported an increased risk of invasive breast cancer in women who took daily CE plus MPA compared to placebo. In this substudy, prior use of estrogen-alone or estrogen plus progestin therapy was reported by 26 percent of the women. The relative risk of invasive breast cancer was 1.24 and the absolute risk was 41 versus 33 cases per 10,000 women-years, for CE plus MPA compared with placebo. Among women who reported prior use of hormone therapy, the relative risk of invasive breast cancer was 1.86, and the absolute risk was 46 versus 25 cases per 10,000 women-years, for CE plus MPA compared with placebo. Among women who reported no prior use of hormone therapy, the relative risk of invasive breast cancer was 1.09, and the absolute risk was 40 versus 36 cases per 10,000 women-years for CE plus MPA compared with placebo. In the same substudy, invasive breast cancers were larger, were more likely to be node positive, and were diagnosed at a more advanced stage in the CE (0.625 mg) plus MPA (2.5 mg) group compared with the placebo group. Metastatic disease was rare, with no apparent difference between the two groups. Other prognostic factors, such as histologic subtype, grade and hormone receptor status did not differ between the groups.

    Consistent with the Women’s Health Initiative (WHI) clinical trials, observational studies have also reported an increased risk of breast cancer for estrogen plus progestin therapy and a smaller, but still increased, risk for estrogen-alone therapy after several years of use. One large meta-analysis of prospective cohort studies reported increased risks that were dependent upon duration of use and could last up to >10 years after discontinuation of estrogen plus progestin therapy and estrogen-alone therapy. Extension of the WHI trials also demonstrated increased breast cancer risk associated with estrogen plus progestin therapy. Observational studies also suggest that the risk of breast cancer was greater, and became apparent earlier, with estrogen plus progestin therapy as compared to the risk with estrogen-alone therapy. However, these studies have not found significant variation in the risk of breast cancer among different estrogen plus progestin combinations, doses, or routes of administration.

    The use of estrogen-alone and estrogen plus progestin has been reported to result in an increase in abnormal mammograms requiring further evaluation.

    All women should receive yearly breast examinations by a healthcare provider and perform monthly breast self-examinations. In addition, mammography examinations should be scheduled based on patient age, risk factors, and prior mammogram results.

    5.3 Severe Hepatic Impairment

    OSPHENA should not be used in women with severe hepatic impairment [see Use in Specific Populations (8.7), and Clinical Pharmacology (12.3)].

  • 6 ADVERSE REACTIONS

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

    6.1 Clinical Trials 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 trials of another drug and may not reflect the rates observed in practice.

    The safety of OSPHENA has been assessed in ten phase 2/3 trials (N=2209) with doses ranging from 5 to 90 mg per day. The duration of treatment in these studies ranged from 6 weeks to 15 months. The majority of women (N=1683) had treatment exposure up to 12 weeks; 847 had up to 52 weeks (1 year) of exposure.

    The incidence rates of thromboembolic and hemorrhagic stroke were 1.13 per thousand women years (1 reported case of thromboembolic stroke) and 3.39 per thousand women years (3 reported cases of hemorrhagic stroke), respectively in OSPHENA 60 mg treatment group and 3.15 (1 case of thromboembolic stroke) and 0 per thousand women years, respectively in placebo. There were 2 reported cases of DVT among the 1459 women in the OSPHENA 60 mg treatment group and 1 case of DVT among the 1136 women in the placebo group.

    Table 1 lists adverse reactions occurring more frequently in the OSPHENA 60 mg treatment group than in placebo and at a frequency ≥1% in the 12-week, double-blind, placebo-controlled clinical trials. Table 2 lists adverse reactions occurring more frequently in the OSPHENA 60 mg treatment group than in placebo and at a frequency ≥1% in all clinical trials up to 52-weeks.

    6.2 Postmarketing Experience

    The following adverse reactions have been identified during post-approval use of ospemifene. Because these reactions are reported voluntarily from a population of uncertain size, it is not possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

    Neoplasms Benign, Malignant and Unspecified (incl. cysts and polyps): endometrial hyperplasia, endometrial cancer

    Immune System Disorders: allergic conditions including hypersensitivity, angioedema

    Nervous System Disorders: headache

    Vascular Disorders: deep vein thrombosis, thrombosis, pulmonary embolism

    Skin and Subcutaneous Tissue Disorders: rash, rash erythematous, rash generalized, pruritus, urticaria

  • 7 DRUG INTERACTIONS

    OSPHENA is primarily metabolized by CYP3A4 and CYP2C9. CYP2C19 and other pathways contribute to the metabolism of ospemifene.

    7.1 Estrogens and Estrogen Agonist/Antagonist

    Do not use OSPHENA concomitantly with estrogens and estrogen agonists/antagonists. The safety of concomitant use of OSPHENA with estrogens and estrogen agonists/antagonists has not been studied.

    7.2 Fluconazole

    Fluconazole, a moderate CYP3A / strong CYP2C9 / moderate CYP2C19 inhibitor, should not be used with OSPHENA. Fluconazole increases the systemic exposure of ospemifene by 2.7-fold. Administration of fluconazole with ospemifene may increase the risk of OSPHENA-related adverse reactions [see Clinical Pharmacology (12.3)].

    7.3 Rifampin

    Rifampin, a strong CYP3A4 / moderate CYP2C9 / moderate CYP2C19 inducer, decreases the systemic exposure of ospemifene by 58%. Therefore, co-administration of OSPHENA with drugs such as rifampin which induce CYP3A4, CYP2C9 and/or CYP2C19 activity would be expected to decrease the systemic exposure of ospemifene, which may decrease the clinical effect [see Clinical Pharmacology (12.3)].

    7.4 Ketoconazole

    Ketoconazole, a strong CYP3A4 inhibitor, increases the systemic exposure of ospemifene by 1.4-fold. Administration of ketoconazole chronically with ospemifene may increase the risk of OSPHENA-related adverse reactions [see Clinical Pharmacology (12.3)].

    7.5 Warfarin

    Repeated administration of ospemifene had no effect on the pharmacokinetics of a single 10 mg dose of warfarin. No study was conducted with multiple doses of warfarin. The effect of ospemifene on clotting time such as the International Normalized Ratio (INR) or prothrombin time (PT) was not studied [see Clinical Pharmacology (12.3)].

    7.6 Highly Protein-Bound Drugs

    Ospemifene is more than 99% bound to serum proteins and might affect the protein binding of other drugs. Use of OSPHENA with other drug products that are highly protein-bound may lead to increased exposure of either that drug or ospemifene [see Clinical Pharmacology (12.3)].

    7.7 Multiple Enzyme Inhibition

    Co-administration of OSPHENA with a drug known to inhibit CYP3A4 and CYP2C9 isoenzymes may increase the risk of OSPHENA-related adverse reactions.

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary

    Not Recommended During Pregnancy

    OSPHENA is contraindicated in women who are or may become pregnant. If this drug is used during pregnancy, or if a woman becomes pregnant while taking this drug, she should be apprised of the potential hazard to a fetus [see Contraindications (4)].

    Based on animal data, OSPHENA is likely to increase the risk of adverse outcomes during pregnancy and labor. Adverse findings at maternally toxic doses included embryofetal lethality in rats and rabbits, and neonatal mortality and difficult labor in rats. The reproductive effects observed are consistent with and are considered to be related to estrogen receptor activity of OSPHENA.

    The background risk of major birth defects and miscarriage for the indicated population is unknown. However, the background risk in the U.S. general population of major birth defects is 2 to 4%, and of miscarriage is 15 to 20% of clinically recognized pregnancies.

    Data

    Animal Data

    The effects of ospemifene on embryo-fetal development were studied in rats (0.1, 1, or 4 mg/kg/day) and rabbits (3, 10, or 30 mg/kg/day) when treated from implantation through organogenesis [Gestation Day (GD) 6-16 in the rat and GD6-18 in the rabbit. In rabbits, there was an increase in the incidence of total resorptions at 30 mg/kg/day (10 times the human exposure based on body surface area mg/m2)]. Drug-induced malformations were not observed in either rats or rabbits.

    The effects of ospemifene on pre- and postnatal development were studied in pregnant rats (0.01, 0.05, and 0.25 mg/kg/day) treated from implantation (GD6) through lactation (Lactation Day (LD) 21). Pregnant rats given 0.05 or 0.25 mg/kg/day ospemifene (0.8% to 4% the human exposure based on body surface area mg/m2) had a significantly prolonged and difficult gestation, increased post-implantation loss, increased number of dead pups at birth, and an increased incidence of postnatal loss. Ospemifene did not induce adverse effects in the surviving offspring of pregnant rats at drug exposures up to 4% the human exposure.

    8.2 Lactation

    Risk Summary

    It is not known whether OSPHENA is excreted in human breast milk. There are no data on the effects of OSPHENA on the breastfed child or the effects on milk production. Do not breastfeed while taking OSPHENA. Ospemifene was excreted in rat milk [see Data].

    Data

    In a nonclinical study, ospemifene was excreted in rat milk and detected at concentrations higher than that in maternal plasma.

    8.4 Pediatric Use

    OSPHENA is not indicated in children. Clinical studies have not been conducted in the pediatric population.

    8.5 Geriatric Use

    Of the 2209 OSPHENA-treated women enrolled in the ten phase 2/3 trials of OSPHENA, >19 percent were 65 years of age or older. No clinically meaningful differences in safety or effectiveness were observed between these women and younger women less than 65 years of age.

    8.6 Renal Impairment

    The pharmacokinetics of ospemifene in women with severe renal impairment (CrCL <30 mL/min) was similar to those in women with normal renal function [see Clinical Pharmacology (12.3)].

    No dose adjustment of OSPHENA is required in women with renal impairment.

    8.7 Hepatic Impairment

    The pharmacokinetics of ospemifene has not been studied in women with severe hepatic impairment (Child-Pugh Class C); therefore, do not use OSPHENA in women with severe hepatic impairment [see Warnings and Precautions (5.3), and Clinical Pharmacology (12.3)].

    No clinically important pharmacokinetic differences with OSPHENA were observed between women with mild to moderate hepatic impairment and healthy women [see Clinical Pharmacology (12.3)].

    No dose adjustment of OSPHENA is required in women with mild (Child-Pugh Class A) or moderate (Child-Pugh Class B) hepatic impairment.

  • 11 DESCRIPTION

    OSPHENA is an estrogen agonist/antagonist. OSPHENA is not a hormone. The chemical structure of ospemifene is shown in Figure 1.

    Figure 1
    Figure 1: Chemical Structure

    The chemical designation is Z-2-[4-(4-chloro-1,2-diphenylbut-1-enyl)phenoxy]ethanol, and has the empirical formula C24H23ClO2, which corresponds to a molecular weight of 378.9. Ospemifene is a white to off-white crystalline powder that is insoluble in water and soluble in ethanol.

    Each OSPHENA tablet contains 60 mg of ospemifene. Inactive ingredients include colloidal silicon dioxide, hypromellose, lactose monohydrate, magnesium stearate, mannitol, microcrystalline cellulose, polyethylene glycol, povidone, pregelatinized starch, sodium starch glycolate, titanium dioxide, and triacetin.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    OSPHENA is an estrogen receptor agonist/antagonist with tissue selective effects. Its biological actions are mediated through binding to estrogen receptors. This binding results in activation of estrogenic pathways in some tissues (agonism) and blockade of estrogenic pathways in others (antagonism).

    12.3 Pharmacokinetics

    Absorption

    Following a single oral administration of OSPHENA 60 mg tablet in postmenopausal women under fasted condition, peak median serum concentration was reached at approximately 2 hours (range: 1 to 8 hours) post-dose (see Figure 2). Mean ospemifene Cmax and AUC0-inf were 533 ng/mL and 4165 ng∙hr/mL, respectively. After a single oral administration of OSPHENA 60 mg tablet in postmenopausal women with a high fat/high calorie (860 kcal) meal, Cmax was reached at approximately 2.5 hours (range: 1 to 6 hours) post-dose. Mean ospemifene Cmax and AUC0-inf were 1198 ng/mL and 7521 ng∙hr/mL, respectively. The absolute bioavailability of ospemifene was not evaluated. Ospemifene exhibits less than dose-proportional pharmacokinetics from 25 to 200 mg with ospemifene capsule formulation. Accumulation of ospemifene with respect to AUC0-inf was approximately 2 after twelve weeks of daily administration. Steady-state was reached after nine days of ospemifene administration.

    Figure 2: Mean Serum Concentration Profile of Ospemifene Following a Single Oral Administration of OSPHENA 60 mg Tablet in Postmenopausal Women Under Fed (N=28) and Fasted (N=91) Conditions

    Figure 2

    Food Effect

    In general, food increased the bioavailability of ospemifene by approximately 2-3 fold. In a cross-study comparison, single dose OSPHENA 60 mg tablet administered with a high fat/high calorie meal (860 kcal) in postmenopausal women increased Cmax and AUC0-inf by 2.3- and 1.7-fold, respectively, compared to fasted condition. Elimination half-life and time to maximum concentration (Tmax) were unchanged in the presence of food. In two food effect studies in healthy males using different ospemifene tablet formulations, Cmax and AUC0-inf increased by 2.3- and 1.8-fold, respectively, with a low fat/low calorie meal (300 kcal) and increased by 3.6- and 2.7-fold, respectively, with a high fat/high calorie meal (860 kcal), compared to fasted condition. OSPHENA should be taken with food [see Dosage and Administration (2.1)].

    Distribution

    OSPHENA is highly (>99 percent) bound to serum proteins. The apparent volume of distribution is 448 L.

    Metabolism

    In vitro experiments with human liver microsomes indicated that ospemifene primarily undergoes metabolism via CYP3A4, CYP2C9, and CYP2C19. The major metabolite was 4-hydroxyospemifene. The apparent total body clearance is 9.16 L/hr using a population approach.

    Excretion

    The apparent terminal half-life of ospemifene in postmenopausal women is approximately 26 hours. Following an oral administration of ospemifene, approximately 75% and 7% of the dose were excreted in feces and urine, respectively. Less than 0.2% of the ospemifene dose was excreted unchanged in urine.

    Use in Specific Populations

    Pediatric

    The pharmacokinetics of ospemifene in pediatric patients has not been evaluated [see Use in Specific Populations (8.4)].

    Geriatric

    No differences in ospemifene pharmacokinetics were detected with regard to age (range 40 to 80 years) [see Use in Specific Populations (8.5)].

    Race

    Race did not have a clinically relevant effect on ospemifene pharmacokinetics.

    Renal Impairment

    In women with severe renal impairment (CrCL <30 mL/min), the Cmax and AUC0-inf for ospemifene following a single 60 mg dose administered with a high fat/high calorie meal were lower by 21% and higher by 20%, respectively [see Use in Specific Populations (8.6)].

    Hepatic Impairment

    In women with mild hepatic impairment (Child-Pugh Class A), the Cmax and AUC0-inf for ospemifene following a single 60 mg dose administered with a high fat/high calorie meal were lower by 21% and 9.1%, respectively, compared to women with normal hepatic function. In women with moderate hepatic impairment (Child-Pugh Class B), the Cmax and AUC0-inf for ospemifene following a single 60 mg dose administered with a high fat/high calorie meal were higher by 1% and 29%, respectively, compared to women with normal hepatic function. The effect of severe hepatic impairment on the pharmacokinetics of ospemifene has not been evaluated [see Warnings and Precautions (5.3), and Use in Specific Populations (8.7)].

    Drug Interactions

    Ospemifene is metabolized primarily by CYP3A4 and CYP2C9. CYP2C19 and other pathways contribute to the metabolism of ospemifene. In order of decreasing potency, ospemifene was suggested to be a weak inhibitor for CYP2B6, CYP2C9, CYP2C19, CYP2C8, CYP2D6, and CYP3A4 in in vitro studies. Ospemifene is not a significant P-glycoprotein substrate in vitro; no in vivo transporter study was conducted.

    Effect of Co-Administered Drugs on the Pharmacokinetics of Ospemifene

    Fluconazole (CYP3A4/CYP2C9/CYP2C19 Inhibitor)

    Fluconazole (a moderate CYP3A / strong CYP2C9 / moderate CYP2C19 inhibitor) 400 mg was given on Day 1 followed by 200 mg on Days 2 to 5 under fasted condition. On Day 5 approximately one hour after fluconazole administration, ospemifene 60 mg was administered after breakfast (two slices of bread with ham, cheese, a few slices of cucumber and/or tomatoes, and juice). Fluconazole 200 mg was taken for three additional days under fasted condition. Multiple doses of fluconazole in fourteen postmenopausal women increased the Cmax and AUC0-inf of ospemifene by 1.7- and 2.7-fold, respectively [see Drug Interactions (7.2)].

    Rifampin (CYP3A4/CYP2C9/CYP2C19 Inducer)

    Rifampin 600 mg was given once daily for 5 consecutive days (given at least one hour before or two hours after a meal) in the late afternoon. On Day 6 after an overnight fast, ospemifene 60 mg was administered in the morning after under fed condition (two slices of bread with ham, cheese, a few slices of cucumber and/or tomatoes, and juice). Multiple doses of rifampin 600 mg in twelve postmenopausal women reduced Cmax and AUC0-inf of ospemifene by 51% and 58%, respectively. Rifampin and other inducers of CYP3A4 are expected to decrease the systemic exposure of ospemifene [see Drug Interactions (7.3)].

    Ketoconazole (CYP3A4 Inhibitor)

    Ketoconazole 400 mg was given once daily for 4 consecutive days after breakfast. On Day 5 after an overnight fast, ketoconazole 400 mg and ospemifene 60 mg were co-administered under fed condition (two slices of bread with ham, cheese, a few slices of cucumber and/or tomatoes, and juice). Ketoconazole administration once daily continued for an additional 3 days (Days 6 to 8). Co-administration of a single 60 mg dose of ospemifene and multiple doses of ketoconazole in twelve postmenopausal women increased Cmax and AUC0-inf by 1.5- and 1.4-fold, respectively [see Drug Interactions (7.4)].

    Omeprazole (CYP2C19 Inhibitor)

    Omeprazole (a moderate CYP2C19 inhibitor) 40 mg was given for 5 days. On Day 5, approximately one hour after omeprazole administration, ospemifene 60 mg was administered after breakfast (two slices of bread with ham, cheese, a few slices of cucumber and/or tomatoes, and juice). Multiple doses of omeprazole in fourteen postmenopausal women increased Cmax and AUC0-inf by 1.20- and 1.17-fold, respectively.

    Effect of Ospemifene on the Pharmacokinetics of the Co-Administered Drug

    Warfarin

    Ospemifene 60 mg was given after a light breakfast (two slices of bread with ham and cheese, and juice) once daily for 12 days in sixteen postmenopausal women who were determined to be rapid metabolizers of CYP2C9 (CYP2C9*1/*1 or CYP2C9*1/*2). On Day 8, a single dose of warfarin 10 mg and vitamin K 10 mg was administered one hour after a light breakfast. The geometric mean ratio (90% CI) for S-warfarin with and without ospemifene for Cmax and AUC0-inf was 0.97 (0.92-1.02) and 0.96 (0.91-1.02), respectively. Multiple doses of ospemifene did not significantly affect the pharmacokinetics of a single dose of warfarin. No study was conducted with multiple doses of warfarin.

    Omeprazole

    Ospemifene 60 mg was administered once daily for 7 days after a light meal in the late afternoon in fourteen postmenopausal women. On Day 8 after an overnight fast, a single 20 mg dose of omeprazole was administered in the morning of at least 10 hrs; ospemifene was not given on Day 8. The geometric mean ratio for the metabolic index (omeprazole/5-hydroxyomeprazole) at the concentration at the 3 hr time point and for AUC0-8hr was 0.97 with and without ospemifene. It is unclear if ospemifene will affect the pharmacokinetics of drugs metabolized by CYP2C19 due to the significant time gap between ospemifene and omeprazole administration.

    Bupropion

    Ospemifene 60 mg was administered once daily for seven consecutive days after the evening meal in sixteen postmenopausal women (not homozygous for CYP2B6*6). On Day 8 after an overnight fast, a single 150 mg dose of sustained release bupropion was administered in morning under fasted condition. The geometric mean ratio (90% CI) for bupropion with and without ospemifene for Cmax and AUC0-inf was 0.82 (0.75-0.91) and 0.81 (0.77-0.86), respectively. The geometric mean ratio (90% CI) for hydroxybupropion, an active metabolite formed via CYP2B6, with and without ospemifene for Cmax and AUC0-inf was 1.16 (1.09-1.24) and 0.98 (0.92-1.04), respectively.

    Midazolam

    Ospemifene 60 mg was administered once daily for 14 days in fifteen postmenopausal women. On Day 14, a single 5 mg dose of midazolam (a CYP3A4 substrate) was administered. All doses of midazolam and ospemifene were administered in morning in the fed state (i.e., after a standard breakfast and at the same time every day). The geometric mean ratio (90% CI) for midazolam with and without ospemifene for Cmax and AUC0-inf was 1.05 (0.95-1.16) and 0.87 (0.82-0.92), respectively.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    Carcinogenesis

    In a 2-year carcinogenicity study in female mice, ospemifene was orally administered at 100, 400, or 1500 mg/kg/day. No evaluation for carcinogenicity was conducted in male mice. There was significant increase in adrenal subcapsular cell adenomas at 4 and 5 times the human exposure based on AUC, and adrenal cortical tumors at 5 times the human exposure. In the ovary, an increase in sex cord/stromal tumors, tubulostromal tumors, granulosa cell tumors, and luteomas was also seen. These findings occurred at doses 2 to 5 times the human exposure based on AUC and are probably related to estrogenic/antiestrogenic effect of ospemifene in mice.

    In a 2-year carcinogenicity study in rats, ospemifene was orally administered at 10, 50, or 300 mg/kg/day. A significant increase in thymomas was recorded for males and thymomas for females at all ospemifene dose levels, or 0.3 to 1.2 times the human exposure based on AUC. In the liver, an increase in hepatocellular tumors was recorded for females at all ospemifene dose levels.

    Mutagenesis

    Ospemifene was not genotoxic in vitro in the Ames test in strains of Salmonella typhimurium or at the thymidine kinase (tk) locus of mouse lymphoma L5178Y cells in the absence and in the presence of a metabolic activator system. In in vivo testing, ospemifene was not genotoxic in a standard mouse bone marrow micronucleus test or in a determination of DNA adducts in the liver of rats.

    Impairment of Fertility

    The effect of ospemifene on fertility was not directly evaluated. In female rats and monkeys, decreases in ovarian and uterine weights, decreased corpora lutea number, increased ovarian cysts, uterine atrophy, and disrupted cycles were observed when given repeated daily oral doses. In male rats, atrophy of the prostate and seminal vesicles was noted. The effects on reproductive organs observed in animals are consistent with the estrogen receptor activity of ospemifene and potential for impairment of fertility.

  • 14 CLINICAL STUDIES

    The effectiveness and safety of OSPHENA on moderate to severe symptoms of vulvar and vaginal atrophy in postmenopausal women were examined in four placebo-controlled clinical trials (three 12-week efficacy trials and one 52-week long-term safety trial). In the four placebo-controlled trials, a total of 1100 women received placebo and 1416 women received 60 mg OSPHENA.

    Trial 1 was a 12-week, randomized, double-blind, placebo-controlled, parallel-group trial that enrolled 826 generally healthy postmenopausal women between 41 to 81 years of age (mean 59 years of age) who at baseline had ≤5 percent superficial cells on a vaginal smear, a vaginal pH >5.0, and who identified at least one moderate to severe vaginal symptom that was considered the most bothersome to her (vaginal dryness, pain during intercourse [dyspareunia], or vaginal irritation/itching). Treatment groups included 30 mg ospemifene (n=282), 60 mg ospemifene (n=276), and placebo (n=268). All women were assessed for improvement in the mean change from baseline to Week 12 for the co-primary efficacy variables of: most bothersome symptom (MBS) of vulvar and vaginal atrophy (defined as the individual moderate to severe symptom that was identified by the woman as most bothersome at baseline), percentage of vaginal superficial and vaginal parabasal cells on a vaginal smear, and vaginal pH. Following completion of 12-weeks, women with an intact uterus were allowed to enroll in a 40-week double-blind extension study, and women without an intact uterus were allowed to enroll in a 52-week open-label extension study.

    Trial 2 was a 12-week, randomized, double-blind, placebo-controlled, parallel-group trial that enrolled 919 generally healthy postmenopausal women between 41 to 79 years of age (mean 59 years of age) who at baseline had ≤5 percent superficial cells on a vaginal smear, a vaginal pH >5.0, and who identified either moderate to severe vaginal dryness (dryness cohort) or moderate to severe dyspareunia (dyspareunia cohort) as most bothersome to her at baseline. Treatment groups included 60 mg ospemifene (n=463) and placebo (n=456). Primary endpoints and study conduct were similar to those in Trial 1.

    Trial 3 was a 12-week, randomized, double-blind, placebo-controlled, parallel-group trial that enrolled 631 generally healthy postmenopausal women between 40 and 80 years of age (mean 60 years of age) who at baseline had ≤5 percent superficial cells on a vaginal smear, a vaginal pH >5.0, and had moderate to severe vaginal dryness as the self-reported most bothersome symptom of VVA. Treatment groups included 60 mg ospemifene (n=316) and placebo (n=315). Primary endpoints and study conduct were similar to those in Trials 1 and 2. In Trial 3, 52 healthy postmenopausal women in the 60 mg ospemifene treatment group and 53 in placebo received treatment for up to 52-weeks.

    Trial 4 was a 52-week, randomized, double-blind, placebo-controlled, long-term safety trial that enrolled 426 generally healthy postmenopausal women between 49 to 79 years of age (mean 62 years of age) with an intact uterus. Treatment groups included 60 mg ospemifene (n=363) and placebo (n=63).

    Effects on Dyspareunia

    In Trials 1 and 2, the modified intent-to-treat population of women treated with ospemifene when compared to placebo demonstrated a statistically significant improvement (least square mean change from baseline to Week 12) in the moderate to severe most bothersome symptom of dyspareunia (Trial 1, p=0.0012 and Trial 2, p<0.0001). See Table 3. A statistically significant increase in the proportion of superficial cells and a corresponding statistically significant decrease in the proportion of parabasal cells on a vaginal smear were also demonstrated (p<0.0001 for both trials). The mean reduction in vaginal pH between baseline and Week 12 was also statistically significant (p<0.0001 for both trials).

    Effects on Vaginal Dryness

    All three trials evaluated the most bothersome symptom of vaginal dryness. Trial 2 did not demonstrate a statistically significant improvement in the moderate to severe most bothersome symptom of vaginal dryness. In Trials 1 and 3, the modified intent-to-treat population of women treated with ospemifene when compared to placebo demonstrated a statistically significant improvement in the moderate to severe most bothersome symptom of vaginal dryness (Trial 1, p=0.0136 and Trial 3, p<0.0001). See Table 4. A statistically significant increase in the proportion of superficial cells and a corresponding statistically significant decrease in the proportion of parabasal cells on a vaginal smear were also demonstrated (p<0.0001 for both trials). The mean reduction in vaginal pH between baseline and Week 12 was also statistically significant (p<0.0001 for both trials).
