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 participants 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 women had a hysterectomy, 68% were Caucasian and 24% were Black. Table 1 summarizes adverse reactions reported in at least 2% of women receiving Angeliq 0.25 mg DRS/0.5 mg E2 and at a higher incidence than subjects receiving placebo.

Different MedDRA terms representing the same medical phenomenon have been grouped together as single adverse reactions to avoid diluting or obscuring the true effect. 6.2 Postmarketing Experience The following additional adverse reactions have been reported during post-approval use of Angeliq. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establishing a causal relationship to drug exposure. Immune System Disorders: Hypersensitivity reactions, including rash, pruritis, and urticaria Reproductive system and breast disorders : Breast cancer Vascular disorders : venous and arterial thromboembolic events (peripheral deep venous occlusion, thrombosis and embolism/pulmonary vascular occlusion, thrombosis, embolism and infarction/myocardial infarction/cerebral infarction and stroke not specified as hemorrhagic)

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. • Start therapy with Angeliq 0.25 mg drospirenone (DRSP)/0.5 mg estradiol (E2) once daily for the treatment of moderate to severe vasomotor symptoms due to menopause. Dosage adjustment should be guided by the clinical response ( 2.1 ) • Start therapy with Angeliq 0.5 mg DRSP/1 mg E2 once daily for the treatment of moderate to severe vulvar and vaginal atrophy due to menopause ( 2.2 ) 2.1 Treatment of Moderate to Severe Vasomotor Symptoms due to Menopause One 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 One Angeliq 0.5 mg DRSP/1 mg E2 tablet taken by mouth once daily. Limitation of Use When prescribing solely for the treatment of moderate to severe symptoms of vulvar and vaginal atrophy, first consider the use of topical vaginal products.

1 INDICATIONS AND USAGE Angeliq is a combination of an estrogen and progestin indicated in a woman with a uterus for the treatment of: • Moderate to severe vasomotor symptoms due to menopause. ( 1.1 ) • Moderate to severe vulvar and vaginal atrophy symptoms due to menopause. ( 1.2 ) Limitation of Use Use estrogen, alone or in combination with a progestogen, at the lowest effective dose and the shortest duration consistent with treatment goals and risks for the individual woman. Re-evaluate postmenopausal women periodically as clinically appropriate to determine whether treatment is still necessary. 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 a woman with a uterus. • 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 a woman with 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 with a uterus.

10 OVERDOSAGE Overdosage of estrogen plus progestogen may cause nausea and vomiting, breast tenderness, abdominal pain, drowsiness and fatigue, and withdrawal bleeding may occur in women. Treatment of overdose consists of discontinuation of Angeliq therapy with institution of appropriate symptomatic care.

7 DRUG INTERACTIONS • Inducers and inhibitors of CYP3A4 may affect estrogen drug metabolism and decrease or increase the estrogen plasma concentration. ( 7.1 ) • Serum potassium concentration may increase in women taking drospirenone with other drugs that have the potential to increase potassium. ( 7.1 ) 7.1 Metabolic Interactions Effect of Drospirenone on Other Drugs 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. Co-administration of DRSP and drugs that may increase serum potassium: There is a potential for an increase in serum potassium in women taking DRSP 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. 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 C max 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 woman 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 and Progestins In vitro and in vivo studies have shown that estrogens and progestins are metabolized partially by cytochrome P450 3A4 (CYP3A4). Therefore, inducers or inhibitors of CYP3A4 may affect estrogen drug metabolism. In a clinical drug-drug interaction study conducted in premenopausal women, once daily co-administration of DRSP 3 mg/E2 1.5 mg containing tablets with strong CYP3A4 inhibitor, ketoconazole 200 mg twice daily for 10 days resulted in a moderate increase of exposure and a mild increase of peak concentration for DRSP. The E2 exposure and peak concentration were unaffected by ketoconazole, although the exposure and peak concentration of estrone (E1) increased. Although no clinically relevant effects on any safety or laboratory parameters including serum potassium were observed, this study only assessed women for 10 days. The clinical impact for a woman taking a DRSP-containing combination hormone and chronic use of a CYP3A4/5 inhibitor is unknown. Substances decreasing the exposure and possibly diminishing the efficacy of estrogens and progestins (enzyme inducers) Inducers of CYP3A4 such as St. John's wort ( Hypericum perforatum ), phenobarbital, carbamazepine, and rifampin may reduce plasma concentrations of estrogens and progestins, possibly resulting in a decrease in therapeutic effects and/or changes in the uterine bleeding profile. Substances increasing the exposure of estrogens and progestins (enzyme inhibitors) Concomitant administration of moderate or strong CYP3A4 inhibitors such as azole antifungals (for example, ketoconazole, itraconazole, voriconazole, fluconazole), verapamil, macrolides (for example, clarithromycin, erythromycin), diltiazem, and grapefruit juice did increase the plasma concentrations of the estrogen or the progestin or both [see Warnings and Precautions (5.2) and Clinical Pharmacology (12.3)]. HIV/HCV protease inhibitors and non-nucleoside reverse transcriptase inhibitors Significant changes (increase or decrease) in the plasma concentrations of estrogen and progestin have been noted in some cases of co-administration with HIV/HCV protease inhibitors or with non-nucleoside reverse transcriptase inhibitors. 7.2 Interaction with Alcohol Acute alcohol ingestion during use of hormone therapy may lead to elevations of circulating E2 concentrations.

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, two estrogen receptors have been identified. These will vary in proportion from tissue to tissue. Circulating estrogens modulate the pituitary secretion of the gonadotropins, luteinizing hormone (LH), and follicle-stimulating hormone (FSH), through a negative feedback mechanism. Estrogens act to reduce the elevated concentrations of these gonadotropins seen in postmenopausal women. DRSP is a synthetic progestin and spironolactone analog with antimineralocorticoid activity. In animals and in vitro , drospirenone has antiandrogenic activity, but no glucocorticoid, antiglucocorticoid, estrogenic, or androgenic activity. Progestins counter estrogenic effects by decreasing the number of nuclear estradiol receptors and suppressing epithelial DNA synthesis in endometrial tissue. 12.2 Pharmacodynamics Generally, a serum estrogen concentration does not predict an individual woman’s therapeutic response to Angeliq nor her risk for adverse outcomes. Likewise, exposure comparisons across different estrogen plus progestin products to infer efficacy or safety for the individual woman may not be valid. 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 T max of serum estradiol was approximately 2 hours after dosing with Angeliq and T max 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.

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 two 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, formed by reduction and subsequent sulfation. These metabolites were shown not to be pharmacologically active. DRSP is also subject to oxidative metabolism catalyzed 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. Excretion DRSP serum concentrations are characterized by a terminal elimination half - life of approximately 36 – 42 hours. Excretion of DRSP was nearly complete after 10 days and amounts excreted were slightly higher in feces compared to urine. DRSP was extensively metabolized and only trace amounts of unchanged DRSP were excreted in urine and feces. At least 20 different metabolites were observed in urine and feces. About 38% to 47% of the metabolites in urine were glucuronide and sulfate conjugates. In feces, about 17% to 20% of the metabolites were excreted as glucuronides and sulfates. Estradiol, estrone, and estriol are excreted in the urine along with glucuronide and sulfate conjugates. 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. 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. 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 3 mg 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 inhibit significantly 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. 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 women (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 C max 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 Estrogens and Progestins: In vitro and in vivo studies have shown that estrogens and progestins are metabolized partially by CYP3A4. Therefore, inducers or inhibitors of CYP3A4 may affect estrogen and progestin drug metabolism [see Drug Interactions (7.1)]. In a clinical drug-drug interaction study conducted in 18 premenopausal women, once daily co-administration of DRSP 3 mg/E2 1.5 mg combination tablets with strong CYP3A4 inhibitor, ketoconazole 200 mg twice daily for 10 days resulted in a 2.30-fold (90% CI: 2.08-2.54) increase of the AUC (0-24) and a 1.66-fold (90% CI: 1.50-1.84) increase of C max for DRSP. The E2 exposure [that is, AUC (0-24) and C max ] was unaffected by ketoconazole, although the AUC(0-24) and C max for E1 increased 1.39-fold (90% CI: 1.27-1.52) and 1.32-fold (90% CI: 1.23-1.42), respectively.

Circulating estrogens modulate the pituitary secretion of the gonadotropins, luteinizing hormone (LH), and follicle-stimulating hormone (FSH), through a negative feedback mechanism. Estrogens act to reduce the elevated concentrations of these gonadotropins seen in postmenopausal women. DRSP is a synthetic progestin and spironolactone analog with antimineralocorticoid activity. In animals and in vitro , drospirenone has antiandrogenic activity, but no glucocorticoid, antiglucocorticoid, estrogenic, or androgenic activity. Progestins counter estrogenic effects by decreasing the number of nuclear estradiol receptors and suppressing epithelial DNA synthesis in endometrial tissue.

12.2 Pharmacodynamics Generally, a serum estrogen concentration does not predict an individual woman’s therapeutic response to Angeliq nor her risk for adverse outcomes. Likewise, exposure comparisons across different estrogen plus progestin products to infer efficacy or safety for the individual woman may not be valid.

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 T max of serum estradiol was approximately 2 hours after dosing with Angeliq and T max 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.

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 two 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, formed by reduction and subsequent sulfation. These metabolites were shown not to be pharmacologically active. DRSP is also subject to oxidative metabolism catalyzed 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. Excretion DRSP serum concentrations are characterized by a terminal elimination half - life of approximately 36 – 42 hours. Excretion of DRSP was nearly complete after 10 days and amounts excreted were slightly higher in feces compared to urine. DRSP was extensively metabolized and only trace amounts of unchanged DRSP were excreted in urine and feces. At least 20 different metabolites were observed in urine and feces. About 38% to 47% of the metabolites in urine were glucuronide and sulfate conjugates. In feces, about 17% to 20% of the metabolites were excreted as glucuronides and sulfates. Estradiol, estrone, and estriol are excreted in the urine along with glucuronide and sulfate conjugates. 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. 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. 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 3 mg 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 inhibit significantly 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. 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 women (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 C max 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 Estrogens and Progestins: In vitro and in vivo studies have shown that estrogens and progestins are metabolized partially by CYP3A4. Therefore, inducers or inhibitors of CYP3A4 may affect estrogen and progestin drug metabolism [see Drug Interactions (7.1)]. In a clinical drug-drug interaction study conducted in 18 premenopausal women, once daily co-administration of DRSP 3 mg/E2 1.5 mg combination tablets with strong CYP3A4 inhibitor, ketoconazole 200 mg twice daily for 10 days resulted in a 2.30-fold (90% CI: 2.08-2.54) increase of the AUC (0-24) and a 1.66-fold (90% CI: 1.50-1.84) increase of C max for DRSP. The E2 exposure [that is, AUC (0-24) and C max ] was unaffected by ketoconazole, although the AUC(0-24) and C max for E1 increased 1.39-fold (90% CI: 1.27-1.52) and 1.32-fold (90% CI: 1.23-1.42), respectively.

14 CLINICAL STUDIES 14.1 Effects on Vasomotor Symptoms in Postmenopausal Women 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 participants was 53 years and 68% were Caucasian. Efficacy for vasomotor symptoms was assessed during the 12 weeks of treatment. Compared to placebo, women 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. Table 4: Summary Tabulation of the Number of Hot Flushes Per Day - Mean Values and Comparisons Between the Active Treatment Group and the Placebo Group, Last Observation Carried Forward Treatment No. of Hot Flushes/Day Time Period (week) Baseline Mean Mean Change from Baseline Mean change from baseline, difference from placebo, 95% confidence interval, and p-value based on an ANCOVA model with treatment and pooled center as factors and baseline measurement as covariate Difference from Placebo (95% CI) p-Values vs. Placebo* DRSP/E2 (0.25 mg/0.5 mg) [n=175] Week 4 10.68 -5.46 -2.02 (-2.89, -1.16) <0.0001 Week 12 10.68 -7.71 -3.17 (-3.97, -2.37) <0.0001 Placebo [n=176] Week 4 10.53 -3.44 - - Week 12 10.53 -4.54 - - 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 in Postmenopausal Women Angeliq 0.25 mg DRSP/0.5 mg E2 In a one year clinical trial, 661 postmenopausal women 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%) women 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 women 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%) women during the treatment period. Eight women 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 woman 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. Table 5: Incidence of Endometrial Hyperplasia after up to 12 Months of Treatment E2 1 mg Angeliq 0.25 mg DRSP/ 0.5 mg E2 Angeliq 0.5 mg DRSP/ 1 mg E2 Total No. Subjects Treated 226 489 227 Total No. of On-Treatment Biopsies Includes evaluable and unevaluable endometrial biopsy results 197 (87.2%) 407 (83.2%) 191 (84.1%) Hyperplasia 8 (4%) 0 (0%) 0 (0%) 14.3 Effects on Uterine Bleeding or Spotting in Postmenopausal Women 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. Figure 2: Proportion of Subjects with any Bleeding/Spotting by Month of Angeliq Use 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.

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. Results of the estrogen-alone substudy, which included 10,739 women (average age of 63 years, range 50 to 79; 75.3 percent White, 15.1 percent Black, 6.1 percent Hispanic, 3.6 percent Other), after an average follow-up of 7.1 years are presented in Table 7.

All deaths, except from breast or colorectal cancer, definite or probable CHD, PE or cerebrovascular disease. 1.08 (0.88-1.32) 53 50 Overall Mortality 1.04 (0.88-1.22) 79 75 Global Index A subset of the events was combined in a "global index," defined as the earliest occurrence of CHD events, invasive breast cancer, stroke, pulmonary embolism, colorectal cancer, hip fracture, or death due to other causes. 1.02 (0.92-1.13) 206 201 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 )] .

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 women 8 [see Warnings and Precautions ( 5.4 ), and Clinical Studies ( 14.5 )].

8.4 Pediatric Use Angeliq is not indicated for use in pediatric patients. Clinical studies have not been conducted in the pediatric population.

8.1 Pregnancy Risk Summary Angeliq is not indicated for use in pregnancy . There are no data with the use of Angeliq in pregnant women, however, epidemiologic studies and meta-analyses have not found an increased risk of genital or nongenital birth defects (including cardiac anomalies or limb-reduction defects) following exposure to combined hormonal contraceptives (estrogens and progestins) before conception or during early pregnancy. In reproduction studies in rats, rabbits and monkeys with oral administration of DRSP either as single compound or in combination with EE, no non-genital teratogenicity was observed. Adverse developmental outcomes like an increase in fetal mortality and a retardation of fetal maturation were seen in rats and rabbits at exposures to DRSP exceeding the human exposure by a factor of >15 (in rats) or >60 (rabbits). Related to the antiandrogenic activity of drospirenone, a feminization of male fetuses and an impairment of male fertility was observed in rats (>150 times the human exposure to drospirenone) but not in monkeys (at up to more than 300 times the human exposure to drospirenone). Due to the large safety margins observed in the animal studies only a low likelihood of an increased risk for human pregnancy was concluded ( see Data ). In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data In an embryo-fetal toxicity study in pregnant rats, DRSP was given from day 6 to 15 of gestation orally at doses of 5, 15 and 45 mg/kg/day, more than 60 times the human exposure starting from the low dose based on AUC of DRSP. A slight increase in postimplantational loss and a slight increase in retardation of fetal development (e.g. delayed ossification of bones of the feet) was seen in the two higher doses. No teratogenicity was observed in rats. In an embryo-fetal study in rabbits, DRSP was given from day 6 to 18 of gestation orally at doses of 10, 30 and 100 mg/kg/day, about 20, 60 and 250 times the human exposure based on AUC. This resulted in a retardation of fetal development (delayed ossification of small bones, multiple fusions of ribs) at the high dose only and in an increase in fetal loss from the mid dose level. No compound-related teratogenicity was seen in rabbits. In a further embryo-fetal toxicity study in pregnant rats, DRSP was orally administered in combination with ethinyl estradiol (100:1) from day 6 to 17 of gestation at doses of 1, 3 and 10 mg/kg/day DRSP, at about 1, 3 and 23 times the human exposure to DRSP on basis of AUC. Maternal toxicity (decreased body weight gain and food consumption) was seen starting at the low dose and an increase of early resorptions at the high dose level. Skeletal variations and retardations were seen in fetuses at the high dose. No malformed fetuses and no effect on the external genitalia of the fetuses were observed. DRSP was administered with ethinyl estradiol (100:1) orally to pregnant rats during late pregnancy from day 14 to 21 of gestation (the period of genital development) at doses of 5, 15 and 45 mg/kg of DRSP, more than 60 times the human exposure starting from the low dose based on AUC of DRSP. Maternal toxicity (decreased body weight gain) and fetal retardation (decreased fetal body weights) were seen starting at the low dose. There was a dose dependent increase in feminization of male rat fetuses starting at the mid dose level (that is, >150 times the human exposure to DRSP). DRSP was administered with ethinyl estradiol (100:1) orally to pregnant cynomolgus monkeys at doses up to 10 mg/kg DRSP, more than 300 times the human exposure based on AUC from day 20 to 90 of gestation. A dose-dependent increase of abortions was observed. No teratogenic or feminization effects were seen in any dose group. DRSP was administered with ethinyl estradiol (100:1) in a peri-postnatal study in rats from day 6 to 16 of gestation and day 1 to 22 postpartum at doses of 5, 15 and 45 mg/kg; more than 60 times the human exposure starting from the low dose based on AUC of DRSP. There was a dose dependent delay in fetal development and an increase in mortality of the F1-generation during the lactational phase. Fertility was impaired in the male offspring at the high dose level.

There was a dose dependent delay in fetal development and an increase in mortality of the F1-generation during the lactational phase. Fertility was impaired in the male offspring at the high dose level. 8.2 Lactation Risk Summary Estrogens plus progestogens are present in human milk and can reduce milk production in breast-feeding women. This reduction can occur at any time but is less likely to occur once breast-feeding is well established. 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. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Angeliq and any potential adverse effects on the breastfed infant from Angeliq or from the underlying maternal condition. 8.4 Pediatric Use Angeliq is not indicated for use in pediatric patients. Clinical studies have not been conducted in the pediatric population. 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 women 8 [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 )]. 8.8 Adrenal Insufficiency Angeliq is contraindicated in patients with adrenal insufficiency because of the risk of hyperkalemia [see Contraindications ( 4 ) and Warnings and Precautions ( 5.2 )].

WARNING: CARDIOVASCULAR DISORDERS, PROBABLE DEMENTIA, BREAST CANCER, and ENDOMETRIAL CANCER Estrogen Plus Progestin Therapy Cardiovascular Disorders and Probable Dementia The Women's Health Initiative (WHI) estrogen plus progestin substudy reported increased risks of pulmonary embolism (PE), deep vein thrombosis (DVT), 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 and 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 )]. Do not use estrogen plus progestogen therapy for the prevention of cardiovascular disease or dementia [see Warnings and Precautions (5.1, 5.4), Clinical Studies (14.4, 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 )] . Only daily oral 0.625 mg CE and 2.5 mg MPA were studied in the estrogen plus progestin substudy of WHI. Therefore, the relevance of the WHI findings regarding adverse cardiovascular events, dementia and breast cancer to lower CE plus other MPA doses, other routes of administration, or other estrogen plus progestin products is not known. Without such data, it is not possible to definitively exclude these risks or determine the extent of these risks for other products. Discuss with your patient the benefits and risks of estrogen plus progestin therapy, taking into account her individual risk profile. Prescribe estrogens with or without progestogens 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 progestogen to estrogen therapy has been shown to reduce the risk of endometrial hyperplasia, which may be a precursor to endometrial cancer. Perform adequate diagnostic measures, including directed or random endometrial sampling when indicated, 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 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 and 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 )] . Do not use estrogen-alone therapy for the prevention of cardiovascular disease or dementia [see Warnings and Precautions ( 5.1 , 5.4 ) and Clinical Studies ( 14.4 , 14.5 )]. Only daily oral 0.625 mg CE was studied in the estrogen-alone substudy of the WHI. Therefore, the relevance of the WHI findings regarding adverse cardiovascular events and dementia to lower CE doses, other routes of administration, or other estrogen-alone products is not known. Without such data, it is not possible to definitively exclude these risks or determine the extent of these risks for other products. Discuss with your patient the benefits and risks of estrogen-alone therapy, taking into account her individual risk profile. Prescribe estrogens with or without progestogens at the lowest effective doses and for the shortest duration consistent with treatment goals and risks for the individual woman.
