  • BOXED WARNING(What is this?)

    WARNING: CARDIOVASCULAR DISORDERS, BREAST CANCER, ENDOMETRIAL CANCER and PROBABLE DEMENTIA

    Estrogen Plus Progestin Therapy

    Cardiovascular Disorders and Probable Dementia

    Estrogen plus progestin therapy should not be used for the prevention of cardiovascular disease or dementia [see Warnings and Precautions (5.1, 5.4) and Clinical Studies (14.4, 14.5)].

    The Women's Health Initiative (WHI) estrogen plus progestin substudy reported an increased risk of deep vein thrombosis (DVT), pulmonary embolism (PE), stroke and myocardial infarction (MI) in postmenopausal women (50 to 79 years of age) during 5.6 years of treatment with daily oral conjugated estrogens (CE) [0.625 mg] combined with medroxyprogesterone acetate (MPA) [2.5 mg], relative to placebo [see Warnings and Precautions (5.1), and Clinical Studies (14.5)].

    The WHI Memory Study (WHIMS) estrogen plus progestin ancillary study of WHI reported an increased risk of developing probable dementia in postmenopausal women 65 years of age or older during 4 years of treatment with daily CE (0.625 mg) combined with MPA (2.5 mg), relative to placebo. It is unknown whether this finding applies to younger postmenopausal women [see Warnings and Precautions (5.4, Use in Specific Populations (8.5), and Clinical Studies (14.5)]. 

    Breast Cancer

    The WHI estrogen plus progestin substudy demonstrated an increased risk of invasive breast cancer [see Warnings and Precautions (5.3), and Clinical Studies (14.4)].

    In the absence of comparable data, these risks should be assumed to be similar for other doses of CE and MPA and other combinations and dosage forms of estrogens and progestins.

    Estrogens with or without progestins should be prescribed at the lowest effective doses and for the shortest duration consistent with treatment goals and risks for the individual woman.

    Estrogen-Alone Therapy

    Endometrial Cancer

    There is an increased risk of endometrial cancer in a woman with a uterus who uses unopposed estrogens. Adding a progestin to estrogen therapy has been shown to reduce the risk of endometrial hyperplasia, which may be a precursor to endometrial cancer. 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 [see Warnings and Precautions (5.3)].

    Cardiovascular Disorders and Probable Dementia

    Estrogen-alone therapy should not be used for the prevention of cardiovascular disease or dementia [see Warnings and Precautions (5.1, 5.4) and Clinical Studies (14.5, 14.4)].

    The WHI estrogen-alone substudy reported increased risks of stroke and DVT in postmenopausal women (50 to 79 years of age) during 7.1 years of treatment with daily oral CE (0.625 mg)-alone relative to placebo [see Warnings and Precautions (5.1), and Clinical Studies (14.5)].

    The WHIMS estrogen-alone ancillary study of WHI reported an increased risk of developing probable dementia in postmenopausal women 65 years of age or older during 5.2 years of treatment with daily CE (0.625 mg)-alone, relative to placebo. It is unknown whether this finding applies to younger postmenopausal women [see Warnings and Precautions (5.4), Use in Specific Populations (8.5), and Clinical Studies (14.5)].

    In the absence of comparable data, these risks should be assumed to be similar for other doses of CE and other forms of estrogens. Estrogens with or without progestins should be prescribed at the lowest effective doses and for the shortest duration consistent with treatment goals and risks for the individual woman.

  • 1 INDICATIONS AND USAGE

    1.1 Treatment of Moderate to Severe Vasomotor Symptoms due to Menopause

    Angeliq 0.25 mg drospirenone (DRSP)/0.5 mg estradiol (E2) is indicated for the treatment of moderate to severe vasomotor symptoms due to menopause in women who have a uterus.
    Angeliq 0.5 mg DRSP/1 mg E2 is indicated for the treatment of moderate to severe vasomotor symptoms associated due to menapause in women who have a uterus.

    1.2 Treatment of Moderate to Severe Symptoms of Vulvar and Vaginal Atrophy due to Menopause

    Angeliq 0.5 mg DRSP/1 mg E2 is indicated for the treatment of moderate to severe symptoms of vulvar and vaginal atrophy due to menopause in women who have a uterus.
    Close
  • 2 DOSAGE AND ADMINISTRATION

    Each pack of Angeliq covers 28 days of treatment. Treatment is continuous, which means that the next pack follows immediately without a break. The tablets are to be swallowed whole with some liquid irrespective of food intake and should preferably be taken at the same time every day. In case a tablet is forgotten, it should be taken as soon as possible. If more than 24 hours have elapsed, the missed tablet should not be taken. If several tablets are forgotten, bleeding may occur.

    Women who do not take estrogens or women who change from a continuous combination product may start treatment at any time. Women changing from a continuous sequential or cyclic hormone therapy (HT) should complete the current cycle of therapy before initiating Angeliq therapy.

    Use of estrogen, alone or in combination with a progestin, should be limited to the lowest effective dose available and for the shortest duration consistent with treatment goals and risks for the individual woman. Patients should be reevaluated periodically as clinically appropriate to determine if treatment is still necessary [see Boxed Warning].

    2.1 Treatment of Moderate to Severe Vasomotor Symptoms due to Menopause

    The dosage is one Angeliq 0.25 mg DRSP/0.5 mg E2 tablet or one Angeliq 0.5 mg DRSP/1 mg E2 tablet taken by mouth once daily.

    2.2 Treatment of Moderate to Severe Symptoms of Vulvar and Vaginal Atrophy due to Menopause

    The dosage is one Angeliq 0.5 mg DRSP/1 mg E2 tablet taken by mouth once daily.

    When prescribing solely for the treatment of symptoms of vulvar and vaginal atrophy, topical vaginal products should be considered.

    Close
  • 5 WARNINGS AND PRECAUTIONS

    5.1 Cardiovascular Disorders

    An increased risk of PE, DVT, stroke and MI have been reported with estrogen plus progestin therapy. An increased risk of stroke and DVT have been reported with estrogen-alone therapy. Should any of these occur or be suspected, estrogen with or without progestin therapy should be discontinued immediately.

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

    Stroke

    In the Women's Health Initiative (WHI) estrogen plus progestin substudy, a statistically significant increased risk of stroke was reported in women 50 to 79 years of age receiving daily CE (0.625 mg) plus MPA (2.5 mg) compared to women in the same age group receiving placebo (33 versus 25 per 10,000 women years) [see Clinical Studies (14.4)]. The increase in risk was demonstrated after the first year and persisted.1 Should a stroke occur or be suspected, estrogen plus progestin therapy 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 10,000 women-years). The increase in risk was demonstrated in year one and persisted [see Clinical Studies (14.4)]. Should a stroke occur or be suspected, estrogen-alone therapy should be discontinued immediately.

    Subgroup analyses of women 50 to 59 years of age suggest no increased risk of stroke for those women receiving CE (0.625 mg)-alone versus those receiving placebo (18 versus 21 per 10,000 women-years).1

    Coronary Heart Disease

    In the WHI estrogen plus progestin substudy, there was a statistically non-significant increased risk of coronary heart disease (CHD) events (defined as nonfatal MI, silent MI, or CHD death) reported in women receiving daily CE (0.625 mg) plus MPA (2.5 mg) compared to women receiving placebo (41 versus 34 per 10,000 women-years).1 An increase in relative risk was demonstrated in year 1, and a trend toward decreasing relative risk was reported in years 2 through 5 [see Clinical Studies (14.4)].

    In the WHI estrogen-alone substudy, no overall effect on CHD events was reported in women receiving estrogen-alone compared to placebo2[see Clinical Studies (14.4)].

    Subgroup analyses of women 50 to 59 years of age suggest a statistically non-significant reduction in CHD events (CE 0.625 mg compared to placebo) in women with less than 10 years since menopause (8 versus 16 per 10,000 women-years).1

    In postmenopausal women with documented heart disease (n=2,763), average 66.7 years of age, in a controlled clinical trial of secondary prevention of cardiovascular disease (Heart and Estrogen/Progestin Replacement Study [HERS]), treatment with daily CE (0.625 mg) plus MPA (2.5 mg) demonstrated no cardiovascular benefit. During an average follow-up of 4.1 years, treatment with CE plus MPA did not reduce the overall rate of CHD events in postmenopausal women with established CHD. There were more CHD events in the CE plus MPA-treated group than in the placebo group in year 1, but not during the subsequent years. Two thousand, three hundred and twenty-one (2,321) women from the original HERS trial agreed to participate in an open label extension of HERS, HERS II. Average follow-up in HERS II was an additional 2.7 years, for a total of 6.8 years overall. Rates of CHD events were comparable among women in the CE plus MPA group and the placebo group in HERS, HERS II, and overall.

    Venous Thromboembolism

    In the WHI estrogen plus progestin substudy, a statistically significant 2-fold greater rate of VTE (DVT and PE) was reported in women receiving daily CE (0.625 mg) plus MPA (2.5 mg) compared to women receiving placebo (35 versus 17 per 10,000 women-years). Statistically significant increases in risk for both DVT (26 versus 13 per 10,000 women-years) and PE (18 versus 8 per 10,000 women-years) were also demonstrated. The increase in VTE risk was demonstrated during the first year and persisted3[see Clinical Studies (14.4)]. Should a VTE occur or be suspected, estrogen plus progestin therapy should be discontinued immediately.

    In the WHI estrogen-alone substudy, the risk of VTE was increased for women receiving daily CE (0.625 mg)-alone compared to placebo (30 versus 22 per 10,000 women-years), although only the increased risk of DVT reached statistical significance (23 versus 15 per 10,000 women-years). The increase in VTE risk was demonstrated during the first 2 years4[see Clinical Studies (14.4)]. Should a VTE occur or be suspected, estrogen-alone therapy should be discontinued immediately.

    If feasible, estrogens 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.

    5.2 Hyperkalemia

    Angeliq contains the progestin DRSP that has antialdosterone activity, including the potential for hyperkalemia in high-risk patients. Angeliq is contraindicated in patients with conditions that predispose to hyperkalemia (renal impairment, hepatic impairment, and adrenal insufficiency).

    Use caution when prescribing Angeliq to women who regularly take other medications that can increase potassium, such as non-steroidal anti-inflammatory drugs (NSAIDs), potassium-sparing diuretics, potassium supplements, angiotensin converting enzyme (ACE) inhibitors, angiotensin-II receptor antagonists, heparin and aldosterone antagonists. Consider checking serum potassium concentrations during the first month of dosing in high-risk patients [see Drug Interactions (7.1)].

    5.3 Malignant Neoplasms

    Breast Cancer

    The most important randomized clinical trial providing information about breast cancer in estrogen plus progestin users is the WHI substudy of daily CE (0.625 mg) plus MPA (2.5 mg). After a mean follow-up of 5.6 years, the estrogen plus progestin substudy reported an increased risk of breast cancer in women who took daily CE plus MPA. 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 groups5[see Clinical Studies (14.4)].

    The most important randomized clinical trial providing information about breast cancer in estrogen-alone users is the WHI substudy of daily CE (0.625 mg)-alone. In the WHI estrogen-alone substudy, after an average follow-up of 7.1 years, daily CE (0.625 mg)-alone was not associated with an increased risk of invasive breast cancer [relative risk [see Clinical Studies (14.4)].

    Consistent with the WHI clinical trial, observational studies have also reported an increased risk of breast cancer for estrogen plus progestin therapy, and a smaller increased risk for estrogen-alone therapy, after several years of use. The risk increased with duration of use, and appeared to return to baseline over about 5 years after stopping treatment (only the observational studies have substantial data on risk after stopping). Observational studies also suggest that the risk of breast cancer was greater, and became apparent earlier, with estrogen plus progestin therapy as compared to estrogen-alone therapy. However, these studies have not generally 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.

    Endometrial Cancer

    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-fold 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 use of estrogens for less than 1 year. The greatest risk appears 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.

    Clinical surveillance of all women using estrogen-alone or estrogen plus progestin therapy 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.

    There is no evidence that the use of natural estrogens results in a different endometrial risk profile than synthetic estrogens of equivalent estrogen dose. Adding a progestin to estrogen therapy in postmenopausal women has been shown to reduce the risk of endometrial hyperplasia, which may be a precursor to endometrial cancer.

    Ovarian Cancer

    The WHI estrogen plus progestin substudy reported a statistically non-significant increased risk of ovarian cancer. After an average follow-up of 5.6 years, the relative risk for ovarian cancer for CE plus MPA versus placebo was 1.58 (95 percent CI 0.77-3.24). The absolute risk for CE plus MPA versus placebo was 4 versus 3 cases per 10,000 women-years.7 In some epidemiological studies, the use of estrogen plus progestin and estrogen-only products, in particular for 5 or more years, has been associated with an increased risk of ovarian cancer. However, the duration of exposure associated with increased risk is not consistent across all epidemiologic studies and some report no association.

    5.4 Probable Dementia

    In the Women’s Health Initiative Memory Study (WHIMS) estrogen plus progestin ancillary study, a population of 4,532 postmenopausal women 65 to 79 years of age was randomized to daily CE (0.625 mg) plus MPA (2.5 mg) or placebo. After an average follow-up of 4 years, 40 women in the CE plus MPA group and 21 women in the placebo group were diagnosed with probable dementia.  The relative risk of probable dementia for CE plus MPA versus placebo was 2.05 (95 percent CI, 1.21-3.48). The absolute risk of probable dementia for CE plus MPA versus placebo was 45 versus 22 cases per 10,000 women-years8 [see Use in Specific Populations (8.5), and Clinical Studies (14.5)].

    In the WHIMS estrogen-alone ancillary study of WHI, a population of 2,947 hysterectomized women 65 to 79 years of age was randomized to daily CE (0.625 mg)-alone or placebo. After an average follow-up of 5.2 years, 28 women in the estrogen-alone group and 19 women in the placebo group were diagnosed with probable dementia. The relative risk of probable dementia for CE-alone versus placebo was 1.49 (95 percent CI, 0.83-2.66). The absolute risk of probable dementia for CE-alone versus placebo was 37 versus 25 cases per 10,000 women-years8 [see Use in Specific Populations (8.5), and Clinical Studies (14.5)].

    When data from the two populations in the WHIMS estrogen-alone and estrogen plus progestin ancillary studies were pooled as planned in the WHIMS protocol, the reported overall relative risk for probable dementia was 1.76 (95 percent CI 1.19-2.60). Since both ancillary studies were conducted in women 65 to 79 years of age, it is unknown whether these findings apply to younger postmenopausal women8 [see Use in Specific Populations (8.5), and Clinical Studies (14.5)].

    5.5 Gallbladder Disease

    A 2- to 4-fold increase in the risk of gallbladder disease requiring surgery in postmenopausal women receiving estrogens has been reported.

    5.6 Hypercalcemia

    Estrogen administration may lead to severe hypercalcemia in women with breast cancer and bone metastases. If hypercalcemia occurs, use of the drug should be stopped and appropriate measures taken to reduce the serum calcium concentration.

    5.7 Visual Abnormalities

    Retinal vascular thrombosis has been reported in women receiving estrogens. Discontinue medication pending examination if there is sudden partial or complete loss of vision, or a sudden onset of proptosis, diplopia, or migraine. If examination reveals papilledema or retinal vascular lesions, estrogens should be permanently discontinued.

    5.8 Elevated Blood Pressure

    In a small number of case reports, substantial increases in blood pressure have been attributed to idiosyncratic reactions to estrogens. In a large, randomized, placebo-controlled clinical trial, a generalized effect of estrogen therapy on blood pressure was not seen.

    5.9 Hypertriglyceridemia

    In women with pre-existing hypertriglyceridemia, estrogen therapy may be associated with elevations of plasma triglycerides leading to pancreatitis. Consider discontinuation of treatment if pancreatitis occurs.

    5.10 Hepatic Impairment and/or Past History of Cholestatic Jaundice

    Estrogens may be poorly metabolized in women with impaired liver function. For women with a history of cholestatic jaundice associated with past estrogen use or with pregnancy, caution should be exercised and in the case of recurrence, medication should be discontinued.

    The clearance of drospirenone was decreased in patients with moderate hepatic impairment.

    5.11 Hypothyroidism

    Estrogen administration leads to increased thyroid-binding globulin (TBG) concentrations. Women with normal thyroid function can compensate for the increased TBG by making more thyroid hormone, thus maintaining free T4 and T3 serum concentrations in the normal range. Women dependent on thyroid hormone replacement therapy who are also receiving estrogens may require increased doses of their thyroid replacement therapy. These women should have their thyroid function monitored in order to maintain their free thyroid hormone concentrations in an acceptable range.

    5.12 Fluid Retention

    Estrogens and progestins may cause some degree of fluid retention. Women with conditions that might be influenced by this factor, such as a cardiac or renal impairment, warrant careful observation when estrogens are prescribed.

    5.13 Hypocalcemia

    Estrogen therapy should be used with caution in women with hypoparathyroidism as estrogen-induced hypocalcemia may occur.

    5.14 Hyponatremia

    As an aldosterone antagonist, drospirenone may increase the possibility of hyponatremia in high-risk patients.

    5.15 Exacerbation of Endometriosis

    Endometriosis may be exacerbated with administration of estrogens.

    5.16 Hereditary Angioedema

    Exogenous estrogens may exacerbate symptoms of angioedema in women with hereditary angioedema.

    5.17 Exacerbation of Other Conditions

    Estrogen therapy may cause an exacerbation of asthma, diabetes mellitus, epilepsy, migraine, porphyria, systemic lupus erythematosus otosclerosis, chorea minor and hepatic hemangiomas and should be used with caution in women with these conditions. In women with hereditary angioedema exogenous estrogens may induce or exacerbate symptoms of angioedema.

    5.18 Laboratory Tests

    Serum follicle stimulating hormone (FSH) and estradiol concentrations have not been shown to be useful in the management of moderate to severe vasomotor symptoms.

    5.19 Interference with Laboratory Tests

    Accelerated prothrombin time, partial thromboplastin time, and platelet aggregation time; increased platelet count; increased factors II, VII antigen, VIII antigen, VIII coagulant activity, IX, X, XII, VII–X complex, II–VII–X complex, and beta-thromboglobulin; decreased concentrations of anti-factor Xa and antithrombin III, decreased antithrombin III activity; increased concentrations of fibrinogen and fibrinogen activity; increased plasminogen antigen and activity.

    Increased TBG concentrations leading to increased circulating total thyroid hormone, as measured by protein-bound iodine (PBI), T4 concentrations (by column or by radioimmunoassay) or T3 concentrations by radioimmunoassay. T3 resin uptake is decreased, reflecting the elevated TBG. Free T4 and free T3 concentrations are unaltered. Women on thyroid replacement therapy may require higher doses of thyroid hormone.

    Other binding proteins may be elevated in serum, for example, corticosteroid binding globulin (CBG), sex hormone binding globulin, leading to increased total circulating corticosteroids and sex steroids, respectively. Free hormone concentrations, such as testosterone and estradiol, may be decreased. Other plasma proteins may be increased (angiotensinogen/renin substrate, alpha-l-antitrypsin, ceruloplasmin).

    Increased plasma high-density lipoprotein (HDL) and HDL2 subfraction concentrations, reduced low-density lipoprotein (LDL) cholesterol concentration, increased triglyceride concentrations.

    Impaired glucose tolerance.

    Reduced response to metyrapone test.

  • 6 ADVERSE REACTIONS

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

    Cardiovascular Disorders [see Boxed Warning, and Warnings and Precautions (5.1)]
    Malignant Neoplasms [see Boxed Warning, and Warnings and Precautions (5.3)]

    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.

    From clinical trials with different dose formulations of Angeliq containing E2 dose ranging from 0.5 mg to 1.0 mg combined with DRSP dose ranging from 0.25 mg to 3 mg:

    The most common adverse reactions were gastrointestinal and abdominal pain, female genital bleeding, breast pain and headache. The frequencies of common adverse reactions, in general, were higher for the Angeliq dose formulation containing E2 1 mg compared to Angeliq containing E2 0.5 mg.
    The most common adverse reactions leading to drug discontinuation in controlled clinical trials were abdominal pain, headache, postmenopausal bleeding, breast tenderness, and weight increased.

    Placebo-Controlled Trial:

    In a placebo-controlled trial evaluating Angeliq 0.25 mg DRSP/0.5 mg E2, 183 postmenopausal women received at least one dose of DRSP 0.25 mg/0.5 mg E2 and 180 received placebo. Study subjects were treated for 3 cycles of 28 days each for a total of 12 weeks of treatment. The median age was 53 years (range: 40-77 years) and over 50% of subjects had a hysterectomy, 68% were Caucasian and 24% were Black. Table 1 summarizes adverse reactions reported in at least 2% of subjects receiving Angeliq 0.25 mg DRS/0.5 mg E2 and at a higher incidence than subjects receiving placebo.

  • 7 DRUG INTERACTIONS

    No formal drug-drug interaction studies have been conducted for Angeliq.

    7.1 Metabolic Interactions

    Effect of Drospirenone on Other Drugs

    Metabolism of DRSP and potential effects of DRSP on hepatic cytochrome P450 (CYP) enzymes have been investigated in in vitro and in vivo studies [see Clinical Pharmacology (12.3)]. In in vitro studies, DRSP did not affect turnover of model substrates of CYP1A2 and CYP2D6, but had an inhibitory influence on the turnover of model substrates of CYP1A1, CYP2C9, CYP2C19 and CYP3A4 with CYP2C19 being the most sensitive enzyme. The potential effect of DRSP on CYP2C19 activity was investigated in a clinical pharmacokinetic study using omeprazole as a marker substrate. No significant effect of DRSP on the systemic clearance of the CYP3A4 product omeprazole sulfone was found. These results demonstrated that DRSP did not inhibit CYP2C19 and CYP3A4 in vivo.

    Two further clinical drug-drug interaction studies using simvastatin and midazolam as marker substrates for CYP3A4, respectively, were performed and the results of these studies demonstrated that pharmacokinetics of the CYP3A4 substrates were not influenced by steady-state DRSP concentrations..

    Based on the available results of in vivo and in vitro studies, it can be concluded that, at clinical dose concentration, DRSP is unlikely to interact significantly with CYP enzymes.

    Co-administration of drospirenone and drugs that may increase serum potassium: There is a potential for an increase in serum potassium in women taking drospirenone with other drugs that may affect electrolytes, such as ACE inhibitors, angiotensin receptor blockers, or NSAIDs, more pronounced in diabetic women [see Warnings and Precautions (5.2), and Clinical Pharmacology (12.3)].

    Electrolytes were studied in postmenopausal women with hypertension and/or diabetes mellitus requiring an ACE inhibitor or angiotensin receptor blocker (ARB). After 28 days of exposure to 1 mg E2 and 3 mg DRSP (n=112) or placebo (n=118). the mean change from baseline in serum potassium was 0.11 mEq/L for the E2/DRSP group and 0.08 mEq/L for the placebo group. None of the subjects with serum potassium concentrations ≥5.5 mEq/L had cardiovascular adverse events.

    A drug-drug interaction study of DRSP 3 mg/E2 1 mg versus placebo was performed in mildly hypertensive postmenopausal women taking enalapril maleate 10 mg twice daily. Potassium concentrations were obtained every other day for a total of 2 weeks in all subjects. Mean serum potassium concentrations in the DRSP/E2 treatment group relative to baseline were 0.22 mEq/L higher than those in the placebo group. On Day 14, the ratios for serum potassium Cmax and AUC in the DRSP/E2 group to those in the placebo group were 0.955 (90% CI: 0.914, 0.999) and 1.01 (90% CI: 0.944, 1.08), respectively. No patient in either treatment group developed hyperkalemia (serum potassium concentrations >5.5 mEq/L).

    Of note, occasional or chronic use of NSAID medication was not restricted in any of the Angeliq clinical trials.

    Effect of Other Drugs on Estrogens

    In vitro and in vivo studies have shown that estrogens are metabolized partially by cytochrome P450 3A4 (CYP3A4). Therefore, inducers or inhibitors of CYP3A4 may affect estrogen drug metabolism. Inducers of CYP3A4 such as St. John's Wort (Hypericum perforatum), phenobarbital, carbamazepine, and rifampin may reduce plasma concentrations of estrogens, possibly resulting in a decrease in therapeutic effects and/or changes in the uterine bleeding profile. Inhibitors of CYP3A4 such as erythromycin, clarithromycin, ketoconazole, itraconazole, ritonavir and grapefruit juice may increase plasma concentrations of estrogens and may result in side effects.

    7.2 Interaction with Alcohol

    Acute alcohol ingestion during use of hormone therapy may lead to elevations of circulating E2 concentrations.

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Angeliq should not be used during pregnancy [see Contraindications (4)]. There appears to be little or no increased risk of birth defects in children born to women who have used estrogens and progestins as an oral contraceptive inadvertently during early pregnancy.

    8.3 Nursing Mothers

    Angeliq should not be used during lactation. Estrogen administration to nursing women has been shown to decrease the quantity and quality of the breast milk. Detectable amounts of estrogens have been identified in the milk of women receiving estrogen. Caution should be exercised when Angeliq is administered to a nursing woman.

    After administration of an oral contraceptive containing DRSP about 0.02% of the DRSP dose was excreted into the breast milk of postpartum women within 24 hours. This results in a maximal daily dose of about 3 mcg DRSP in an infant.

    8.4 Pediatric Use

    Angeliq is not indicated in children. Clinical studies have not been conducted in the pediatric populations.

    8.5 Geriatric Use

    There have not been sufficient numbers of geriatric women involved in clinical studies utilizing Angeliq to determine whether those over 65 years of age differ from younger women in their response to Angeliq.

    The Women’s Health Initiative Studies

    In the WHI estrogen plus progestin substudy (daily CE [0.625 mg] plus MPA [2.5 mg] versus placebo), there was a higher relative risk of nonfatal stroke and invasive breast cancer in women greater than 65 years of age [see Warnings and Precautions (5.1, 5.3) and Clinical Studies (14.4)].

    In the WHI estrogen-alone substudy (daily CE [0.625 mg] versus placebo), there was a higher relative risk of stroke in women greater than 65 years of age [see Warnings and Precautions (5.1)and Clinical Studies (14.4)].

    The Women’s Health Initiative Memory Study

    In the WHIMS ancillary studies of postmenopausal women 65 to 79 years of age, there was an increased risk of developing probable dementia in women receiving estrogen plus progestin or estrogen-alone when compared to placebo [see Warnings and Precautions (5.4), and Clinical Studies (14.5)].

    Since both ancillary studies were conducted in women 65 to 79 years of age, it is unknown whether these findings apply to younger postmenopausal women8[see Warnings and Precautions (5.4), and Clinical Studies (14.5)].

    8.6 Renal Impairment

    Angeliq is contraindicated in patients with renal impairment because of the risk of hyperkalemia [see Contraindications (4), Warnings and Precautions (5.2 and Clinical Pharmacology (12.3)].

    8.7 Hepatic Impairment

    Angeliq is contraindicated in patients with hepatic impairment because of the risk of increased DRSP exposure and subsequent hyperkalemia [see Contraindications (4), Warnings and Precautions (5.10)  and Clinical Pharmacology (12.3)].

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Endogenous estrogens are largely responsible for the development and maintenance of the female reproductive system and secondary sexual characteristics. Although circulating estrogens exist in a dynamic equilibrium of metabolic interconversions, estradiol (E2) is the principal intracellular human estrogen and is substantially more potent than its metabolites, estrone and estriol, at the receptor level.

    The primary source of estrogen in normally cycling adult women is the ovarian follicle, which secretes 70 to 500 mcg of estradiol daily, depending on the phase of the menstrual cycle. After menopause, most endogenous estrogen is produced by conversion of androstenedione, secreted by the adrenal cortex, to estrone in the peripheral tissues. Thus, estrone and the sulfate-conjugated form, estrone sulfate, are the most abundant circulating estrogens in postmenopausal women.

    Estrogens act through binding to nuclear receptors in estrogen-responsive tissues. To date, 2 estrogen receptors have been identified. These will

    12.2 Pharmacodynamics

    No clinical pharmacology studies have been conducted for Angeliq.

    12.3 Pharmacokinetics

    Absorption

    Serum concentrations of DRSP reach peak concentrations approximately 1 hour after administration of Angeliq and mean absolute bioavailability of DRSP ranges from 76–85%. Following oral administration, the median Tmax of serum estradiol was approximately 2 hours after dosing with Angeliq and Tmax ranged between 0.3-10 hours.

    The pharmacokinetics of DRSP are dose proportional within the dose range of 0.25–4 mg. Following daily dosing of Angeliq, steady state DRSP concentrations were observed after 10 days. Mean accumulation ratios for DRSP and estradiol were 2.3 and 2.0, respectively, following multiple doses of 0.5 mg DRSP/1 mg E2, and 2.6 and 1.6, respectively, following multiple doses of 0.25 mg DRSP/0.5 mg E2. Mean concentrations at 2 hours for DRSP ranged between 5.9 and 6.7 ng/mL after treatment with Angeliq (0.5 mg DRSP/1 mg E2) for 365 days. Mean steady state serum DRSP and E2 concentrations are shown in Figure 1, and a summary of primary pharmacokinetic parameters following the administration of 0.25 mg DRSP/0.5 mg E2 or 0.5 mg DRSP/1 mg E2 at steady state is presented in Table 3.

    Effect of Food

    The effect of food on the absorption and bioavailability of DRSP and E2 have not been investigated following the administration of Angeliq. However, clinical studies with different formulations containing DRSP or E2 have shown that the bioavailability of both drugs is not affected by concomitant food intake.

    Distribution

    The mean volume of distribution of DRSP is 4.2 L/kg. DRSP does not bind to SHBG or CBG but binds about 97% to other serum proteins. The distribution of exogenous estrogens is similar to that of endogenous estrogens. Estrogens are widely distributed in the body and are generally found in higher concentrations in the sex hormone target organs. Estradiol circulates in the blood bound to SHBG (37%) and to albumin (61%), while only approximately 1%2% is unbound.

    Metabolism

    Mean clearance of DRSP is 1.2 mL/min/kg. DRSP is extensively metabolized after oral administration. The 2 main metabolites of DRSP found in human plasma were identified to be the acid form of DRSP generated by opening of the lactone ring and the 4,5-dihydrodrospirenone-3-sulfate, both of which are formed without the involvement of the CYP system. These metabolites were shown not to be pharmacologically active. In in vitro studies with human liver microsomes, DRSP was metabolized only to a minor extent mainly by CYP3A4.

    Exogenous estrogens are metabolized in the same manner as endogenous estrogens. Circulating estrogens exist in a dynamic equilibrium of metabolic interconversions. These transformations take place mainly in the liver. Estradiol is converted reversibly to estrone, and both can be converted to estriol, which is a major urinary metabolite. Estrogens also undergo enterohepatic recirculation via sulfate and glucuronide conjugation in the liver, biliary secretion of conjugates into the intestine, and hydrolysis in the gut followed by reabsorption. In postmenopausal women, a significant proportion of the circulating estrogens exist as sulfate conjugates, especially estrone sulfate, which serves as a circulating reservoir for the formation of more active estrogens.

    Use in Specific Populations

    Geriatric

    No pharmacokinetic studies were conducted for Angeliq in the geriatric population.

    Pediatric

    No pharmacokinetic studies were conducted for Angeliq in a pediatric population.

    Gender

    Angeliq is indicated for use in women only.

    Race

    No studies were done to determine the effect of race on the pharmacokinetics of Angeliq.

    Hepatic Impairment

    Angeliq is contraindicated in patients with hepatic impairment [see Contraindications (4) and Warnings and Precautions (5.10)]. The mean exposure to DRSP in women with moderate liver impairment is approximately three times the exposure in women with normal liver function.

    Renal Impairment

    Angeliq is contraindicated in patients with renal impairment [see Contraindications (4) and Warnings and Precautions (5.2) ].

    The effect of renal impairment on the pharmacokinetics of DRSP (3 mg daily for 14 days) and the effects of DRSP on serum potassium concentrations were investigated in female subjects (n=28, age 30-65 years) with creatinine clearance (CLcr) ≥ 80 mL/min (11 patients), and CLcr of 50-79 mL/min (10 patients) and CLcr of 30-49 mL/min (7 patients). All subjects were on a low potassium diet. During the study 7 subjects continued the use of potassium-sparing drugs for the treatment of the underlying illness. On the 14th day (steady-state) of DRSP treatment, the serum DRSP concentrations were on average 37% higher in the group with CLcr of 30-49 mL/min compared to those in the group with normal renal function (CLcr ≥ 80 mL/min). Serum DRSP concentrations in the group with CLcr of 50-79 mL/min were comparable to those in the group with CLcr ≥ 80 mL/min. DRSP treatment was well tolerated by all groups. DRSP treatment did not show any clinically significant effect on serum potassium concentration. Although hyperkalemia was not observed in the study, in 5 of the 7 subjects who continued use of potassium sparing drugs during the study, individual mean serum potassium concentrations increased by up to 0.33 mEq/L. Therefore, potential exists for hyperkalemia to occur in subjects with renal impairment whose serum potassium is in the upper reference range, and who are concomitantly using potassium sparing drugs.

    Drug Interactions

    No formal drug interaction studies have been conducted for Angeliq.

    Metabolic Interactions

    Effects of Drospirenone on Other Drugs: Metabolism of DRSP and potential effects of DRSP on hepatic CYP enzymes have been investigated in in vitro and in vivo studies. In in vitro studies, DRSP did not affect turnover of model substrates of CYP1A2 and CYP2D6, but had an inhibitory influence on the turnover of model substrates of CYP1A1, CYP2C9, CYP2C19 and CYP3A4 with CYP2C19 being the most sensitive enzyme.

    The potential effect of DRSP on CYP2C19 activity was investigated in a clinical pharmacokinetic study using omeprazole as a marker substrate. In the study with 24 postmenopausal women [including 12 women with homozygous (wild type) CYP2C19 genotype and 12 women with heterozygous CYP2C19 genotype] the daily oral administration of 3mg DRSP for 14 days did not affect the systemic clearance of the CYP2C19 substrate omeprazole (40 mg) and the CYP2C19 product 5-hydroxy-omeprazole. Furthermore, no significant effect of DRSP on the systemic clearance of the CYP3A4 product omeprazole sulfone was found. These results demonstrated that DRSP did not inhibit CYP2C19 and CYP3A4 in vivo.

    Two further clinical drug-drug interaction studies using simvastatin and midazolam as marker substrates for CYP3A4 were each performed in 24 healthy, postmenopausal women. The results of these studies demonstrated that pharmacokinetics of the CYP3A4 substrates were not influenced by steady-state DRSP concentrations achieved after administration of 3 mg DRSP/day.

    Based on the available results of in vivo and in vitro studies, it can be concluded that, at clinical dose concentration, DRSP is unlikely to interact significantly with CYP enzymes.

    There is a potential for an increase in serum potassium in women taking drospirenone with other drugs that may affect electrolytes, such as ACE inhibitors, angiotensin receptor blockers, or NSAIDs.

    Electrolytes were studied in 230 postmenopausal women with hypertension and/or diabetes mellitus requiring an ACE inhibitor or angiotensin receptor blocker (ARB). Of these, 26 patients had a creatinine clearance >50 mL/min to <80 mL/min. Patients were given 1 mg E2 and 3 mg DRSP (n=112) or placebo (n=118) over 28 days. Non-diabetic patients also received ibuprofen 1200 mg/day for 5 days during the study. There was a single case of serum potassium >6 mEq/L and a single case of serum sodium <130 mEq/L on treatment, both occurring following five days of ibuprofen therapy in two women taking E2/DRSP. Serum potassium concentrations ≥5.5 mEq/L were observed in 8 (7.3%) E2/DRSP-treated subjects (3 diabetic and 5 non-diabetic) and in 3 (2.6%) placebo-treated subjects (2 diabetic and 1 non-diabetic). After 28 days of exposure, the mean change from baseline in serum potassium was 0.11 mEq/L for the E2/DRSP group and 0.08 mEq/L for the placebo group. None of the subjects with serum potassium concentrations ≥5.5 mEq/L had cardiovascular adverse events.

    A drug-drug interaction study of DRSP 3 mg/E2 1 mg versus placebo was performed in 24 mildly hypertensive postmenopausal women taking enalapril maleate 10 mg twice daily. Potassium concentrations were obtained every other day for a total of 2 weeks in all subjects. Mean serum potassium concentrations in the DRSP/E2 treatment group relative to baseline were 0.22 mEq/L higher than those in the placebo group. Serum potassium concentrations also were measured at multiple timepoints over 24 hours at baseline and on Day 14. On Day 14, the ratios for serum potassium Cmax and AUC in the DRSP/E2 group to those in the placebo group were 0.955 (90% CI: 0.914, 0.999) and 1.01 (90% CI: 0.944, 1.08), respectively. No patient in either treatment group developed hyperkalemia (serum potassium concentrations >5.5 mEq/L).

    Of note, occasional or chronic use of NSAID medication was not restricted in any of the Angeliq clinical trials.

    Effects of Other Drugs on Estrogen: In vitro and in vivo studies have shown that estrogens are metabolized partially by CYP3A4. Therefore, inducers or inhibitors of CYP3A4 may affect estrogen drug metabolism. Inducers of CYP3A4 such as St. John’s Wort (Hypericum perforatum) preparations, phenobarbital, carbamazepine, and rifampin may reduce plasma concentrations of estrogens, possibly resulting in a decrease in therapeutic effects and/or changes in the uterine bleeding profile. Inhibitors of CYP3A4 such as erythromycin, clarithromycin, ketoconazole, itraconazole, ritonavir and grapefruit juice may increase plasma concentrations of estrogens and may result in side effects.

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    In a 24-month oral carcinogenicity study in mice dosed with 10 mg/kg/day DRSP alone or 1+0.01, 3+0.03 and 10+0.1 mg/kg/day of DRSP and ethinyl estradiol, 0.24 to 10.3 times the exposure (AUC of drospirenone) of women taking a 1 mg dose, there was an increase in carcinomas of the Harderian gland in the group that received the high dose of drospirenone alone. In a similar study in rats given 10 mg/kg/day drospirenone alone or 0.3+0.003, 3+0.03 and 10+0.1 mg/kg/day drospirenone and ethinyl estradiol, 2.3 to 51.2 times the exposure of women taking a 1 mg dose, there was an increased incidence of benign and total (benign and malignant) adrenal gland pheochromocytomas in the group receiving the high dose of drospirenone. Drospirenone was not mutagenic in a number of in vitro (Ames, Chinese Hamster Lung gene mutation and chromosomal damage in human lymphocytes) and in vivo (mouse micronucleus) genotoxicity tests. Drospirenone increased unscheduled DNA synthesis in rat hepatocytes and formed adducts with rodent liver DNA but not with human liver DNA.

    14.1 Effects on Vasomotor Symptoms

    Angeliq 0.25 mg DRSP/0.5 mg E2

    The efficacy of Angeliq 0.25 mg DRSP/0.5 mg E2 for reducing the frequency and severity of moderate to severe vasomotor symptoms was evaluated in a randomized, double-blind, placebo-controlled trial. A total of 735 postmenopausal women ≥ 40 years of age with a minimum of 7 to 8 moderate to severe hot flashes daily or 50 to 60 moderate to severe hot flashes weekly were randomized to one of the two doses of Angeliq, including DRSP 0.25 mg/0.5 mg E2, estrogen monotherapy, or placebo. The median age of study subjects was 53 years and 68% were Caucasian. Efficacy for vasomotor symptoms was assessed during the 12 weeks of treatment. Compared to placebo, subjects receiving Angeliq 0.25 mg DRSP/0.5 mg E2 achieved statistically significant reduction in the frequency and severity of moderate to severe vasomotor symptoms at Week 4 and at Week 12. The mean difference in daily reduction of frequency of hot flushes between Angeliq 0.25 mg DRSP/0.5 mg E2 and placebo were approximately -2 episodes at Week 4 and -3 episodes at Week 12. Table 4 shows the mean number of hot flushes in the Angeliq 0.25 mg DRSP/0.5 mg E2 and placebo groups and the treatment difference between Angeliq 0.25 mg DRSP/0.5 mg E2 and placebo treatment at Week 4 and at Week 12.

    Angeliq 0.5 mg DRSP/1 mg E2

    Support for treatment of vasomotor symptoms and vaginal and vulvar atrophy was shown through bioequivalence of the E2 component of the Angeliq combination product with a currently marketed 1 mg E2 product. The multiple-dose bioequivalence study evaluated the bioequivalence of E2 from a tablet containing DRSP (2 mg) and E2 (1 mg) relative to E2 1 mg tablet. Angeliq 0.5 mg DRSP/1 mg E2 tablets met the criteria for bioequivalence to the E2 1 mg comparator.

    14.2 Effects on Endometrium

    Angeliq 0.25 mg DRSP/0.5 mg E2

    In a one year clinical trial, 661 postmenopausal subjects were treated with Angeliq 0.25 mg DRSP/0.5 mg E2 (N=489) or a comparator drug (N=172). Endometrial biopsies were performed on 407 (83.2%) subjects in the Angeliq group during the treatment period. No endometrial hyperplasias occurred during or after one year of treatment. See Table 5.

    Angeliq 0.5 mg DRSP/1 mg E2

    In a one year clinical trial of 1,142 postmenopausal subjects treated with 1 mg E2 alone or 1 mg E2 + 0.5, 1, 2, or 3 mg DRSP, endometrial biopsies were performed on 966 (84.6%) subjects during the treatment period. Eight subjects in the E2 monotherapy group developed endometrial hyperplasia (4 simple hyperplasia with no cytological atypia, 3 complex hyperplasia with no cytological atypia, and 1 complex hyperplasia with cytological atypia), and one subject in the 1 mg E2+2 mg DRSP group developed simple hyperplasia with no cytological atypia. Table 5 shows that there were no diagnoses of endometrial hyperplasia in the Angeliq group.

    14.3 Effects on Uterine Bleeding or Spotting

    Angeliq 0.5 mg DRSP/1 mg E2 and Angeliq 0.25 mg DRSP /0.5 mg E2 were evaluated in separate one-year clinical trials investigating the endometrial safety in postmenopausal women with an intact uterus.

    Over 12 months in the double-blind trials, the proportions of women with any bleeding or spotting decreased over time. At one year, approximately 22% of women treated with Angeliq 0.5 mg/E2 1.0 mg and 15% of women treated with Angeliq 0.25 mg/E2 0.5 mg had any uterine bleeding or spotting. See Figure 2.

    14.4 Women's Health Initiative Studies

    The WHI enrolled approximately 27,000 predominantly healthy postmenopausal women in two substudies to assess the risks and benefits of daily oral CE (0.625 mg)-alone or in combination with MPA (2.5 mg) compared to placebo in the prevention of certain chronic diseases. The primary endpoint was the incidence of CHD defined as nonfatal MI, silent MI and CHD death], with invasive breast cancer as the primary adverse outcome. A "global index" included the earliest occurrence of CHD, invasive breast cancer, stroke, PE, endometrial cancer (only in the CE plus MPA substudy), colorectal cancer, hip fracture, or death due to other cause. These substudies did not evaluate the effects of CE plus MPA or CE-alone on menopausal symptoms.

    WHI Estrogen plus Progestin Substudy

    The WHI estrogen plus progestin substudy was stopped early. According to the predefined stopping rule, after an average follow-up of 5.6 years of treatment, the increased risk of breast cancer and cardiovascular events exceeded the specified benefits included in the "global index." The absolute excess risk of events included in the “global index” was 19 per 10,000 women-years.

    For those outcomes included in the WHI “global index” that reached statistical significance after 5.6 years of follow-up, the absolute excess risks per 10,000 women-years in the group treated with CE plus MPA were 7 more CHD events, 8 more strokes, 10 more PEs, and 8 more invasive breast cancers, while the absolute risk reductions per 10,000 women-years were 6 fewer colorectal cancers and 5 fewer hip fractures.

    Results of the CE plus MPA substudy, which included 16,608 women (average 63 years of age, range 50 to 79; 83.9 percent White, 6.8 percent Black, 5.4 percent Hispanic, 3.9 percent Other) are presented in Table 6. These results reflect centrally adjudicated data after an average follow-up of 5.6 years.

    Timing of the initiation of estrogen therapy relative to the start of menopause may affect the overall risk benefit profile. The WHI estrogen plus progestin substudy stratified by age showed in women 50-59 years of age, a non-significant trend toward reduced risk for overall mortality [HR 0.69 (95 percent CT 0.44-1.07)].

    WHI Estrogen-Alone Substudy

    The WHI estrogen-alone substudy was stopped early because an increased risk of stroke was observed, and it was deemed that no further information would be obtained regarding the risks and benefits of estrogen alone in predetermined primary endpoints.

    For those outcomes included in the WHI "global index" that reached statistical significance, the absolute excess risk per 10,000 women-years in the group treated with CE-alone was 12 more strokes, while the absolute risk reduction per 10,000 women-years was 7 fewer hip fractures.9 The absolute excess risk of events included in the "global index" was a non-significant 5 events per 10,000 women-years. There was no difference between the groups in terms of all-cause mortality.

    No overall difference for primary CHD events (nonfatal MI, silent MI and CHD death) and invasive breast cancer incidence in women receiving CE-alone compared with placebo was reported in final centrally adjudicated results from the estrogen-alone substudy, after an average follow-up of 7.1 years.

    Centrally adjudicated results for stroke events from the estrogen-alone substudy, after an average follow-up of 7.1 years, reported no significant difference in distribution of stroke subtype or severity, including fatal strokes, in women receiving CE-alone compared to placebo. Estrogen-alone increased the risk for ischemic stroke, and this excess risk was present in all subgroups of women examined.10

    Timing of the initiation of estrogen therapy relative to the start of menopause may affect the overall risk benefit profile. The WHI estrogen-alone substudy stratified by age showed in women 50 to 59 years of age, a non-significant trend toward reduced risk for CHD [HR 0.63 (95 percent CI 0.36-1.09)] and overall mortality [HR 0.71 (95 percent CT 0.46-1.11)].

    14.5 Women's Health Initiative Memory Study

    The WHIMS estrogen plus progestin ancillary study of WHI enrolled 4,532 predominantly healthy postmenopausal women 65 years of age and older (47 percent were 65 to 69 years of age, 35 percent were 70 to 74 years of age, and 18 percent were 75 years of age and older) to evaluate the effects of daily CE (0.625 mg) plus MPA (2.5 mg) on the incidence of probable dementia (primary outcome) compared to placebo.

    After an average follow-up of 4 years, the relative risk of probable dementia for CE plus MPA versus placebo was 2.05 (95 percent CI 1.21-3.48). The absolute risk of probable dementia for CE plus MPA was 45 versus 22 cases per 10,000 women-years. Probable dementia as defined in this study included Alzheimer’s disease (AD, vascular dementia (VaD) and mixed type (having features of both AD and VaD). The most common classification of probable dementia in the treatment group and the placebo group was AD. Since the ancillary study was conducted in women 65 to 79 years of age, it is unknown whether these findings apply to younger postmenopausal women [see Warnings and Precautions (5.4), and Use in Specific Populations (8.5)].

    The WHIMS estrogen-alone ancillary study of WHI enrolled 2,947 predominantly healthy hysterectomized postmenopausal women 65 to 79 years of age and older (45 percent were age 65 to 69 years of age, 36 percent were 70 to 74 years of age, and 19 percent were 75 years of age and older) to evaluate the effects of daily CE (0.625 mg) on the incidence of probable dementia (primary outcome) compared to placebo.

    After an average follow-up of 5.2 years, the relative risk of probable dementia for CE-alone versus placebo was 1.49 (95 percent CI, 0.83 - 2.66). The absolute risk of probable dementia for CE-alone versus placebo was 37 versus 25 cases per 10,000 women-years. Probable dementia as defined in this study included AD, VaD, and mixed type (having features of both AD and VaD). The most common classification of probable dementia in the treatment group and placebo group was AD. Since the ancillary study was conducted in women 65 to 79 years of age, it is unknown whether these findings apply to younger postmenopausal women [see Warnings and Precautions (5.4) and Use in Specific Populations (8.5)].

    When data from the two populations were pooled as planned in the WHIMS protocol, the reported overall RR for probable dementia was 1.76 (95 percent CI 1.19-2.60). Differences between groups became apparent in the first year of treatment. It is unknown whether these findings apply to younger postmenopausal women [see Warnings and Precautions (5.4) and Use in Specific Populations (8.5)].

    What is Angeliq?

    Angeliq is a medicine that contains 2 kinds of hormones, estrogen and progestin.

    Angeliq 0.25 mg drospirenone (DRSP)/0.5 mg estradiol (E2) and Angeliq 0.5 mg DRSP/1 mg E2 are both used after menopause to reduce moderate to severe hot flashes.
    Estrogens are hormones made by a woman's ovaries. The ovaries normally stop making estrogens when a woman is between 45 to 55 years old. This drop in body estrogen levels causes the "change of life" or menopause (the end of monthly menstrual periods). Sometimes, both ovaries are removed during an operation before natural menopause takes place. The sudden drop in estrogen levels causes "surgical menopause."
    When the estrogen levels begin dropping, some women develop very uncomfortable symptoms, such as feelings of warmth in the face, neck, and chest, or sudden strong feelings of heat and sweating ("hot flashes" or "hot flushes"). In some women, the symptoms are mild, and they will not need estrogens. In other women, symptoms can be more severe. You and your healthcare provider should talk regularly about whether you still need treatment with Angeliq.
    Angeliq 0.5 mg drospirenone (DRSP)/1 mg estradiol (E2) is used after menopause to treat moderate to severe dryness, itching, and burning in or around the vagina. You and your healthcare provider should talk regularly about whether you still need treatment with Angeliq to control these problems. If you use Angeliq only to treat dryness, itching, and burning in and around your vagina, talk with your healthcare provider about whether a topical vaginal product would be better for you.

    Who should not take Angeliq?

    Do not start taking Angeliq if you:

    have had your uterus removed (hysterectomy).
    Angeliq contains a progestin to decrease the chances of getting cancer of the uterus. If you do not have a uterus, you do not need a progestin and you should not use Angeliq.
    have unusual vaginal bleeding. Vaginal bleeding after menopause may be a warning sign of cancer of the uterus (womb). Your healthcare provider should check any unusual vaginal bleeding to find out the cause.
    currently have or have had certain cancers. Estrogens may increase the chances of getting certain types of cancers, including cancer of the breast or uterus. If you have or had cancer, talk with your healthcare provider about whether you should take Angeliq.
    had a stroke or heart attack in the past year.
    currently have or have had blood clots.
    have kidney disease, liver disease, or disease of your adrenal glands. Angeliq contains drospirenone which may increase the potassium level in your blood. Liver, kidney, or adrenal gland disease may also increase the potassium level in your blood.
    have been diagnosed with a bleeding disorder.
    are allergic to Angeliq or any of its ingredients. See the end of this leaflet for a list of ingredients in Angeliq.
    are pregnant or plan to become pregnant.

    What should I tell my healthcare provider before taking Angeliq?

    Before you take Angeliq, tell your healthcare provider if you:

    have or have had problems with your adrenal glands.
    have high levels of fat in your blood (triglycerides)
    asthma (wheezing)
    epilepsy (seizures)
    migraine
    endometriosis
    lupus
    hypertension (high blood pressure)
    problems with your heart, liver, thyroid or kidneys
    benign breast disease
    have high calcium in your blood
    have high potassium levels in your blood
    have low sodium levels in your blood
    are pregnant or plan to become pregnant. Angeliq is not for pregnant women. If you think you may be pregnant, you should have a pregnancy test and know the results before you start taking Angeliq.
    are breastfeeding or planning to breastfeed. You should not breastfeed while taking Angeliq. The hormone in Angeliq can decrease the amount of breast milk you make. Also, the hormone in Angeliq can pass into your milk. Talk to your healthcare provider about the best way to feed your baby if you take Angeliq.

    Tell your healthcare provider about all the medicines you take, including prescription and nonprescription medicines, vitamins, and herbal supplements. Some medicines may affect how Angeliq works. Angeliq may also affect how your other medicines work. Angeliq may increase the potassium level in your blood and some medicines may also increase potassium level. In some situations, your healthcare provider may recommend testing your blood for potassium level.

    Know the medicines you take. Keep a list of them to show your doctor and pharmacist when you get a new medicine.

    If you are going to have surgery or will be on bed rest. Your healthcare provider will let you know if you need to stop taking Angeliq.

    How should I take Angeliq?

    Take Angeliq tablets whole. Do not break, crush, dissolve, or chew Angeliq tablets before swallowing. If you cannot swallow Angeliq tablets whole, tell your healthcare provider. You may need a different medicine.
    If you miss a dose of Angeliq, take it as soon as possible.
    If more than 24 hours have passed since you missed a dose of Angeliq, you should not take the missed dose.
    Estrogens should be used at the lowest dose possible for your treatment only as long as needed. You and your healthcare provider should talk regularly (for example, every 3 to 6 months) about whether you still need treatment with Angeliq.
