Climara Drug Interactions
Information about and practical guidance on preventing clinically significant drug/drug and drug/food interactions that may occur in people taking the drug.7 DRUG INTERACTIONS 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) 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 adverse reactions. • Inducers and/or inhibitors of CYP3A4 may affect estrogen drug metabolism and decrease or increase the estrogen plasma concentration.

Clinical pharmacology
Information about the clinical pharmacology and actions of the drug in humans.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 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, which is 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 vary in proportion from tissue to tissue. Circulating estrogens modulate the pituitary secretion of the gonadotropins, luteinizing hormone (LH) and FSH, through a negative feedback mechanism. Estrogens act to reduce the elevated levels of these hormones seen in postmenopausal women. 12.2 Pharmacodynamics Generally, a serum estrogen concentration does not predict an individual woman’s therapeutic response to Climara nor her risk for adverse outcomes. Likewise, exposure comparisons across different estrogen products to infer efficacy or safety for the individual woman may not be valid. 12.3 Pharmacokinetics Absorption Transdermal administration of Climara produces mean serum concentrations of estradiol comparable to those produced by premenopausal women in the early follicular phase of the ovulatory cycle. The pharmacokinetics of estradiol following application of the Climara transdermal system were investigated in 197 healthy postmenopausal women in six studies. In five of the studies, the Climara transdermal system was applied to the abdomen, and in a sixth study, application to the buttocks and abdomen were compared. The Climara transdermal delivery system continuously releases estradiol which is transported across intact skin leading to sustained circulating levels of estradiol during a 7-day treatment period. The systemic availability of estradiol after transdermal administration is about 20 times higher than that after oral administration. This difference is due to the absence of first pass metabolism when estradiol is given by the transdermal route. In a bioavailability study, the Climara 6.5 cm 2 was studied with the Climara 12.5 cm 2 as reference. The mean estradiol levels in serum from the two sizes are shown in Figure 1. Figure 1: Mean Serum 17ß -Estradiol Concentrations versus Time Profile following Application of a 6.5 cm2 Transdermal System and Application of a 12.5 cm2 Climara Transdermal System Dose proportionality was demonstrated for the Climara 6.5 cm 2 transdermal system as compared to the Climara 12.5 cm 2 transdermal system in a 2-week crossover study with a 1-week washout period between the two-transdermal systems in 24 postmenopausal women. Dose proportionality was also demonstrated for the Climara transdermal system (12.5 cm 2 and 25 cm 2 ) in a 1-week study conducted in 54 postmenopausal women. The mean steady state levels (C avg ) of the estradiol during the application of Climara 25 cm 2 and 12.5 cm 2 on the abdomen were about 80 and 40 pg/mL, respectively. In a 3-week multiple application study in 24 postmenopausal women, the 25 cm 2 Climara transdermal system produced average peak estradiol concentrations (C max ) of approximately 100 pg/mL. Trough values at the end of each wear interval (C min ) were approximately 35 pg/mL. Nearly identical serum curves were seen each week, indicating little or no accumulation of estradiol in the body. Serum estrone peak and trough levels were 60 and 40 pg/mL, respectively. In a single dose, randomized, crossover study conducted to compare the effect of site of application, 38 postmenopausal women wore a single Climara 25 cm 2 transdermal system for 1 week on the abdomen and buttocks. The estradiol serum concentration profiles are shown in Figure 2. Values of C max and C avg were, respectively, 25 percent and 17 percent higher with the buttock application than with the abdomen application. Figure 2: Observed Mean (± SE) Estradiol Serum Concentrations for a One Week Application of the Climara Transdermal System (25 cm 2 ) to the Abdomen and Buttocks of 38 Postmenopausal Women Table 2 provides a summary of estradiol pharmacokinetic parameters determined during evaluation of the Climara transdermal system. Table 2: Pharmacokinetic Summary (Mean Estradiol Values) Climara Delivery Rate Surface Area (cm 2 ) Application Site No. of Subjects Dosing C max (pg/mL) C min (pg/mL) C avg (pg/mL) 0.025 6.5 Abdomen 24 Single 32 17 22 0.05 12.5 Abdomen 102 Single 71 29 41 0.1 25 Abdomen 139 Single 147 60 87 0.1 25 Buttock 38 Single 174 71 106 The relative standard deviation of each pharmacokinetic parameter after application to the abdomen averaged 50 percent, which is indicative of the considerable intersubject variability associated with transdermal drug delivery. The relative standard deviation of each pharmacokinetic parameter after application to the buttock was lower than that after application to the abdomen (for example, for C max 39 percent versus 62 percent, and for C avg 35 percent versus 48 percent). Fig 1 Fig 2 Distribution 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. Estrogens circulate in the blood largely bound to SHBG and albumin. Metabolism 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 intestine 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 Estradiol, estrone, and estriol are excreted in the urine along with glucuronide and sulfate conjugates. Adhesion An open-label study of adhesion potentials of placebo transdermal systems that correspond to the 6.5 cm 2 and 12.5 cm 2 sizes of Climara was conducted in 112 healthy women of 45 to 75 years of age. Each woman applied both transdermal systems weekly, on the upper outer abdomen, for 3 consecutive weeks. It should be noted that lower abdomen and upper quadrant of the buttock are the approved sites of application for Climara. The adhesion assessment was done visually on Days 2, 4, 5, 6, 7 of each week of transdermal system wear. A total of 1,654 adhesion observations were conducted for 333 transdermal systems of each size. Of these observations, approximately 90 percent showed essentially no lift for both the 6.5 cm 2 and 12.5 cm 2 transdermal systems. Of the total number of transdermal systems applied, approximately 5 percent showed complete detachment for each size. Adhesion potentials of the 18.75 cm 2 and 25 cm 2 sizes of transdermal systems (0.075 mg per day and 0.1 mg per day) have not been studied.

General information about the drug product, including the proprietary and established name of the drug, the type of dosage form and route of administration to which the label applies, qualitative and quantitative ingredient information, the pharmacologic or therapeutic class of the drug, and the chemical name and structural formula of the drug.11 DESCRIPTION Climara (estradiol transdermal system), is designed to release estradiol continuously upon application to intact skin. Six (6.5, 9.375, 12.5, 15, 18.75 and 25 cm 2 ) systems are available to provide nominal in vivo delivery of 0.025, 0.0375, 0.05, 0.06, 0.075 or 0.1 mg respectively of estradiol per day. The period of use is 7 days. Each system has a contact surface area of either 6.5, 9.375, 12.5, 15, 18.75 or 25 cm 2 , and contains 2, 2.85, 3.8, 4.55, 5.7 or 7.6 mg of estradiol USP respectively. The composition of the systems per unit area is identical. Estradiol USP is a white, crystalline powder, chemically described as estra-1,3,5(10)-triene-3, 17β-diol. It has an empirical formula of C 18 H 24 O 2 and molecular weight of 272.38. The structural formula is: The Climara transdermal system comprises three layers. Proceeding from the visible surface toward the surface attached to the skin, these layers are: 1. A translucent polyethylene film. 2. An acrylate adhesive matrix containing estradiol USP. 3. A protective liner of siliconized or fluoropolymer-coated polyester film is attached to the adhesive surface and must be removed before the system can be used. The active component of the transdermal system is estradiol. The remaining components of the transdermal system (acrylate copolymer adhesive, fatty acid esters, and polyethylene backing) are pharmacologically inactive. Chemical Structure Patch Diagram
Dosage and administration
Information about the drug product’s dosage and administration recommendations, including starting dose, dose range, titration regimens, and any other clinically sigificant information that affects dosing recommendations.2 DOSAGE AND ADMINISTRATION Generally, when estrogen is prescribed for a postmenopausal woman with a uterus, consider addition of a progestogen to reduce the risk of endometrial cancer. Generally, a woman without a uterus does not need to use a progestogen in addition to her estrogen therapy. In some cases, however, hysterectomized women who have a history of endometriosis may need a progestogen [see Warnings and Precautions ( 5.2 , 5.14 )] . Use estrogen-alone, or in combination with a progestogen at the lowest effective dose and for the shortest duration consistent with treatment goals and risks for the individual woman. Reevaluate postmenopausal women periodically as clinically appropriate to determine if treatment is still necessary. • Start therapy with Climara 0.025 mg per day applied to the skin once-weekly. Dosage adjustment should be guided by the clinical response ( 2.1 ) • Place Climara on a clean, dry area of the lower abdomen (below the umbilicus) or upper quadrant of the buttock. Do not apply Climara to the breasts ( 2.5 ) 2.1 Treatment of Moderate to Severe Vasomotor Symptoms due to Menopause Start therapy with Climara 0.025 mg per day applied to the skin once weekly. Make dosage adjustments based on the clinical response. Attempt to taper or discontinue Climara at 3 to 6 month intervals. 2.2 Treatment of Moderate to Severe Symptoms of Vulvar and Vaginal Atrophy due to Menopause Start therapy with Climara 0.025 mg per day applied to the skin once weekly. Make dosage adjustments based on the clinical response. Attempt to taper or discontinue Climara at 3 to 6 month intervals. 2.3 Treatment of Hypoestrogenism due to Hypogonadism, Castration, or Primary Ovarian Failure Start therapy with 0.025 mg per day applied to the skin once weekly. Make dose adjustment based on the clinical response. 2.4 Prevention of Postmenopausal Osteoporosis Start therapy with Climara 0.025 mg per day applied to the skin once weekly. 2.5 Application of the Climara Transdermal System Site Selection • Place the adhesive side of Climara on a clean, dry area of the lower abdomen or the upper quadrant of the buttock. • Do not apply Climara to or near the breasts. • Rotate the sites of application, with an interval of at least 1-week allowed between applications to the same site. • Select an area that is not oily, damaged, or irritated. Avoid the waistline, since tight clothing may rub the transdermal system off. • Avoid application to areas where sitting would dislodge Climara. Application • Apply Climara immediately after opening the pouch and removing the protective liner. • Press Climara firmly in place with the fingers for at least 10 seconds, making sure there is good contact, especially around the edges. • If the system lifts, apply pressure to maintain adhesion. • In the event that a system falls off, reapply it to a different location. If the old system cannot be reapplied, apply a new system for the remainder of the 7-day dosing interval. • Wear only one system at any one time during the 7-day dosing interval. • Swimming, bathing, or using a sauna while using Climara has not been studied, and these activities may decrease the adhesion of the system and the delivery of estradiol. 2.6 Removal of the Climara Transdermal System • Remove Climara carefully and slowly to avoid irritation of the skin. • If any adhesive remains on the skin after removal of Climara, allow the area to dry for 15 minutes and then gently rub the area with an oil-based cream or lotion to remove the adhesive residue. • Used patches still contain some active hormones. Carefully fold each patch in half so that it sticks to itself before throwing it away.

Information necessary for patients to use the drug safely and effectively.Patient Package Insert Patient Information Climara (Klī-mâr-uh) (estradiol transdermal system) Read this Patient Information before you start using Climara and each time you get a refill. There may be new information. This information does not take the place of talking to your healthcare provider about your menopausal symptoms or your treatment. What is the most important information I should know about Climara (an estrogen hormone)? • Using estrogen-alone may increase your chance of getting cancer of the uterus (womb). • Report any unusual vaginal bleeding right away while you are using Climara. 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. • Do not use estrogen-alone to prevent heart disease, heart attacks, strokes, or dementia (decline in brain function). • Using estrogen-alone may increase your chances of getting strokes or blood clots. • Using estrogen-alone may increase your chance of getting dementia, based on a study of women age 65 years of age and older. • Do not use estrogens with progestogens to prevent heart disease, heart attacks, strokes or dementia. • Using estrogens with progestogens may increase your chances of getting heart attacks, strokes, breast cancer, or blood clots. • Using estrogens with progestogens may increase your chance of getting dementia, based on a study of women age 65 years of age and older. • Only one estrogen-alone product and dose have been shown to increase your chances of getting strokes, blood clots, and dementia. Only one estrogen with progestogen product and dose have been shown to increase your chances of getting heart attacks, strokes, breast cancer, blood clots, and dementia. • Because other products and doses have not been studied in the same way, it is not known how the use of Climara will affect your chances of these conditions. You and your healthcare provider should talk regularly about whether you still need treatment with Climara. What is Climara? Climara is a prescription medicine patch (transdermal system) that contains estradiol (an estrogen hormone). What is Climara used for? The Climara is 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 and 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 estrogen levels begin dropping, some women develop very uncomfortable symptoms, such as feelings of warmth in the face, neck, and chest, or sudden intense feelings of heat and sweating ("hot flashes" or "hot flushes"). In some women, the symptoms are mild, and they will not need to use estrogens. In other women, symptoms can be more severe. • Treat moderate to severe menopausal changes in and around the vagina You and your healthcare provider should talk regularly about whether you still need treatment with Climara to control these problems. If you use Climara only to treat your menopausal changes in and around your vagina, talk with your healthcare provider about whether a topical vaginal product would be better for you. • Treat certain conditions in women before menopause if their ovaries do not produce enough estrogens naturally • Help reduce your chances of getting osteoporosis (thin weak bones) Osteoporosis from menopause is a thinning of the bones that makes them weaker and easier to break. If you use Climara only to prevent osteoporosis due to menopause, talk with your healthcare provider about whether a different treatment or medicine without estrogens might be better for you. You and your healthcare provider should talk regularly about whether you still need treatment with Climara. Who should not use Climara? Do not start using Climara if you: • 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. • have been diagnosed with a bleeding disorder • currently have or have had certain cancers Estrogens may increase the chance of getting certain types of cancers, including cancer of the breast or uterus (womb). If you have or have had cancer, talk with your healthcare provider about whether you should use Climara. • had a stroke or heart attack • currently have or have had blood clots • currently have or have had liver problems • are allergic to Climara or any of the ingredients in it. See the list of ingredients in Climara at the end of this leaflet. Before you use Climara, tell your healthcare provider about all of your medical conditions, including if you: • have any 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. • have any other medical conditions that may become worse while you are using Climara Your healthcare provider may need to check you more carefully if you have certain conditions, such as asthma (wheezing), epilepsy (seizures), diabetes, migraine, endometriosis, lupus, angioedema (swelling of face and tongue), or problems with your heart, liver, thyroid, kidneys, or have high calcium levels in your blood. • are going to have surgery or will be on bed rest. Your healthcare provider will let you know if you need to stop using Climara. • are pregnant or think you may be pregnant. Climara is not for pregnant women. • are breastfeeding The hormone in Climara can pass into your breast milk. Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Some medicines may affect how Climara works. Climara may also affect how your other medicines work. Keep a list of your medicines and show it to your healthcare provider and pharmacist when you get new medicine. How should I use Climara? For detailed instructions, see the step-by-step instructions for using Climara at the end of this Patient Information. • Use Climara exactly as your healthcare provider tells you to use it. • Climara is for skin use only. • Change your Climara patch 1 time each week or every 7 days. • Apply your Climara patch to a clean, dry area on your lower abdomen or buttocks. This area must be clean, dry, and free of powder, oil or lotion for your patch to stick to your skin. • Apply your Climara patch to a different area of your abdomen or your buttocks each time. Do not use the same application site 2 times in the same week. • Do not apply Climara to your breasts. • If you forget to apply a new Climara patch, apply a new patch as soon as possible. • You and your healthcare provider should talk regularly (every 3 to 6 months) about the dose you are using and whether you still need treatment with Climara. How to Change Climara • When changing Climara, peel off the used patch slowly from the skin. • After removal of Climara if any adhesive residue remains on your skin, allow the area to dry for 15 minutes. Then, gently rub the area with an oil-based cream or lotion to remove the adhesive from your skin. • Apply the new patch to a different area of your abdomen or buttocks. This area must be clean, dry, and free of powder, oil or lotion. Do not use the same site again for at least 1 week after removal of an old patch. What are the possible side effects of Climara? Side effects are grouped by how serious they are and how often they happen when you are treated. Serious, but less common side effects include: Call your healthcare provider right away if you get any of the following warning signs or any other unusual symptoms that concern you: • new breast lumps • unusual vaginal bleeding • changes in vision or speech • sudden new severe headaches • severe pains in your chest or legs with or without shortness of breath, weakness and fatigue Common side effects of Climara include: • headache • breast tenderness or pain • irregular vaginal bleeding or spotting • stomach or abdominal cramps, bloating • nausea and vomiting • hair loss • fluid retention • vaginal yeast infection • redness and/or irritation at the patch placement site These are not all the possible side effects of Climara. For more information, ask your healthcare provider or pharmacist. Tell your healthcare provider if you have any side effects that bother you or do not go away. You may report side effects to FDA at 1-800-FDA-1088. You may report side effects to Bayer Healthcare Pharmaceuticals at 1-888-842-2937. What can I do to lower my chances of a serious side effect with Climara? • Talk with your healthcare provider regularly about whether you should continue using Climara. • If you have a uterus, talk with your healthcare provider about whether the addition of a progestogen is right for you. In general, the addition of a progestogen is generally recommended for a woman with a uterus to reduce the chance of getting cancer of the uterus (womb). • See your healthcare provider right away if you get vaginal bleeding while using Climara. • Have a pelvic exam, breast exam and mammogram (breast X-ray) every year unless your healthcare provider tells you something else. If members of your family have had breast cancer or if you have ever had breast lumps or an abnormal mammogram, you may need to have breast exams more often. • If you have high blood pressure, high cholesterol (fat in the blood), diabetes, are overweight, or if you use tobacco, you may have higher chances for getting heart disease. Ask your healthcare provider for ways to lower your chances of getting heart disease. How should I store and throw away used Climara? • Store Climara at room temperature 68°F to 77°F (20°C to 25°C). • Do not store Climara patches outside of their pouches. Apply immediately upon removal from the protective pouch. • Used patches still contain estrogen. To throw away the patch, fold the sticky side of the patch together, place it in a sturdy child-proof container, and place this container in the trash. Used patches should not be flushed in the toilet. Keep Climara and all medicines out of the reach of children. General information about the safe and effective use of Climara.

Clinical studies
This field may contain references to clinical studies in place of detailed discussion in other sections of the labeling.14 CLINICAL STUDIES 14.1 Effects on Vasomotor Symptoms in Postmenopausal Women A study of 214 women 25 to 74 years of age met the qualification criteria and were randomly assigned to one of the three treatment groups: 72 to the 0.05 mg estradiol patch, 70 to the 0.1 mg estradiol patch, and 72 to placebo. Potential participants were postmenopausal women in good general health who experienced vasomotor symptoms. Natural menopause patients had not menstruated for at least 12 months and surgical menopause patients had undergone bilateral oophorectomy at least 4 weeks before evaluation for study entry. In order to enter the 11-week treatment phase of the study, potential participants must have experienced a minimum of five moderate to severe hot flushes per week, or a minimum of 15 hot flushes of any severity per week, for 2 consecutive weeks. Women wore the patches in a cyclical fashion (three weeks on and one week off). During treatment, all women used diaries to record the number and severity of hot flushes. Women were monitored by clinic visits at the end of weeks 1, 3, 7, and 11 and by telephone at the end of weeks 4, 5, 8, and 9. Adequate data for the analysis of efficacy was available from 191 subjects. The results are presented as the mean ± SD number of flushes in each of the 3 treatment weeks of each 4-week cycle. In the 0.05 mg estradiol group, the mean weekly hot flush rate across all treatment cycles decreased from 46 ± 6.5 at baseline to 20 ± 3 (-67 percent). The 0.1 mg estradiol group had a decline in the mean weekly hot flush rate from 52 ± 4.4 at baseline to 16 ± 2.4 (-72 percent). In the placebo group, the mean weekly hot flush rate declined from 53 ± 4.5 at baseline to 46 ± 6.5 (-18.1 percent). Compared with placebo, the 0.05 mg and 0.1 mg estradiol groups showed a statistically significantly larger mean decrease in hot flushes across all treatment cycles (P<0.05). When the response to treatment was analyzed for each of the three cycles of therapy, similar statistically significant differences were observed between both estradiol treatment groups and the placebo group during all treatment cycles. In a double-blind, placebo-controlled, randomized study of 187 women receiving Climara 0.025 mg per day or placebo continuously for up to three 28-day cycles, the Climara 0.025 mg per day dosage was shown to be statistically better than placebo at weeks 4 and 12 for relief of both the frequency and severity of moderate to severe vasomotor symptoms.

A total of 129 participating women were allocated to receive active treatment with 4 different doses of estradiol patches (6.5, 12.5, 15, 25 cm 2 ) and 46 participating women were allocated to receive placebo patches. Seventy-seven percent of the randomized women (100 on active drug and 34 on placebo) contributed data to the analysis of percent change of anterior-posterior (A-P) spine BMD, the primary efficacy variable (see Figure 3). A statistically significant overall treatment effect at each timepoint was noted, implying bone preservation for all active treatment groups at all timepoints, as opposed to bone loss for placebo at all timepoints. Figure 3: Mean Percent Change from Baseline in Lumbar Spine (A-P View) Bone Mineral Density By Treatment and Time Last Observation Carried Forward Figure 3: Mean Percent Change from Baseline in Lumbar Spine (A-P View) Bone Mineral Density By Treatment and Time Last Observation Carried Forward Percent change in BMD of the total hip (see Figure 4) was also statistically significantly different from placebo for all active treatment groups. This figure is based on 74 percent of the randomized women (95 on active drug and 34 on placebo). Figure 4: Mean Percent Change from Baseline in Total Hip by Treatment and Time Last Observation Carried Forward fig 3 fig 4 14.3 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 causes. These substudies did not evaluate the effects of CE-alone or CE plus MPA on menopausal symptoms. 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 risk and benefits of estrogen-alone in predetermined primary endpoints. Results of the estrogen-alone substudy, which included 10,739 women (average 63 years of age, 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 4.

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. See Table 4. 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 the distribution of stroke subtype and severity, including fatal strokes, in women receiving estrogen-alone compared to placebo. Estrogen-alone increased the risk of ischemic stroke, and this excess risk was present in all subgroups of women examined. 10 See Table 4. Timing of initiation of estrogen-alone 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 [hazard ratio (HR) 0.63 (95 percent CI, 0.36-1.09)] and overall mortality [HR 0.71 (95 percent CI, 0.46-1.11)] . 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 invasive 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 reduction 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, 6.5 percent Black, 5.4 percent Hispanic, 3.9 percent Other), are presented in Table 5 . These results reflect centrally adjudicated data after an average follow-up of 5.6 years.

Event Relative Risk CE/MPA vs. placebo (95% nCI Nominal confidence intervals unadjusted for multiple looks and multiple comparisons. ) CE/MPA n = 8,506 Placebo n = 8,102 Absolute Risk per 10,000 Women-years CHD events 1.23 (0.99-1.53) 41 34 Non-fatal MI 1.28 (1.00-1.63) 31 25 CHD death 1.10 (0.70-1.75) 8 8 All strokes 1.31 (1.03-1.68) 33 25 Ischemic stroke 1.44 (1.09-1.90) 26 18 Deep vein thrombosis Not included in "global index". 1.95 (1.43-2.67) 26 13 Pulmonary embolism 2.13 (1.45-3.11) 18 8 Invasive breast cancer Includes metastatic and non-metastatic breast cancer, with the exception of in situ breast cancer. 1.24 (1.01-1.54) 41 33 Colorectal cancer 0.61 (0.42-0.87) 10 16 Endometrial cancer 0.81 (0.48-1.36) 6 7 Cervical cancer 1.44 (0.47-4.42) 2 1 Hip fracture 0.67 (0.47-0.96) 11 16 Vertebral fractures 0.65 (0.46-0.92) 11 17 Lower arm/wrist fractures 0.71 (0.59-0.85) 44 62 Total fractures 0.76 (0.69-0.83) 152 199 Overall mortality All deaths, except from breast or colorectal cancer, definite or probable CHD, PE or cerebrovascular disease. 1.00 (0.83-1.19) 52 52 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, endometrial cancer, colorectal cancer, hip fracture, or death due to other causes. 1.13 (1.02-1.25) 184 165 Timing of initiation of estrogen plus progestin 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 to 59 years of age a non-significant trend toward reduced risk for overall mortality [HR 0.69 (95 percent CI, 0.44-1.07)] . 14.4 Women's Health Initiative Memory Study 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 65 to 69 years of age; 36 percent were 70 to 74 years of age; 19 percent were 75 years of age and older) to evaluate the effects of daily CE (0.625 mg)-alone 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 the study included Alzheimer’s disease (AD), vascular dementia (VaD) and mixed types (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 ( 5.3 ), and Use in Specific Populations ( 8.5 )] . The WHIMS estrogen plus progestin ancillary study 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 versus placebo was 45 versus 22 cases per 10,000 women-years. Probable dementia as defined in the study included AD, VaD and mixed types (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 ( 5.3 ), and Use in Specific Populations ( 8.5 )] . When data from the two populations 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). 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 ( 5.3 ), and Use in Specific Populations ( 8.5 )]

Geriatric use
Information about any limitations on any geriatric indications, needs for specific monitoring, hazards associated with use of the drug in the geriatric population.8.5 Geriatric Use There have not been sufficient numbers of geriatric women involved in clinical studies utilizing Climara to determine whether those over 65 years of age differ from younger subjects in their response to Climara. The Women’s Health Initiative Studies In the WHI estrogen-alone substudy (daily CE [0.625 mg]-alone versus placebo), there was a higher relative risk of stroke in women greater than 65 years of age [see Clinical Studies ( 14.3 )] . 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 Clinical Studies ( 14.3 )] . 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-alone or estrogen plus progestin when compared to placebo [see Warnings and Precautions ( 5.3 ), and Clinical Studies ( 14.4 )] . 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 ( 5.3 ), and Clinical Studies ( 14.4 )] .
Pediatric use
Information about any limitations on any pediatric indications, needs for specific monitoring, hazards associated with use of the drug in any subsets of the pediatric population (such as neonates, infants, children, or adolescents), differences between pediatric and adult responses to the drug, and other information related to the safe and effective pediatric use of the drug.8.4 Pediatric Use In general, Climara is not indicated for use in pediatric patients. Clinical studies have not been conducted in the pediatric population. If estrogen is administered to patients whose bone growth is not complete, periodic monitoring of bone metabolism and effects on epiphyseal centers is recommended during estrogen administration.
Pregnancy
Information about effects the drug may have on pregnant women or on a fetus. This field may be ommitted if the drug is not absorbed systemically and the drug is not known to have a potential for indirect harm to the fetus. It may contain information about the established pregnancy category classification for the drug. (That information is nominally listed in the teratogenic_effects field, but may be listed here instead.)8.1 Pregnancy Risk Summary Climara is not indicated for use in pregnancy. There are no data with the use of Climara in pregnant women; however, epidemiologic studies and meta-analyses have not found an increased risk of genital or nongenital birth defects (including cardiac anomalies and limb-reduction defects) following exposure to combined hormonal contraceptives (estrogens and progestins) before conception or during early pregnancy. 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.
Use in specific populations
Information about use of the drug by patients in specific populations, including pregnant women and nursing mothers, pediatric patients, and geriatric patients.8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Risk Summary Climara is not indicated for use in pregnancy. There are no data with the use of Climara in pregnant women; however, epidemiologic studies and meta-analyses have not found an increased risk of genital or nongenital birth defects (including cardiac anomalies and limb-reduction defects) following exposure to combined hormonal contraceptives (estrogens and progestins) before conception or during early pregnancy. 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. 8.2 Lactation Risk Summary Estrogens 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. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Climara and any potential adverse effects on the breastfed child from Climara or from the underlying maternal condition. 8.4 Pediatric Use In general, Climara is not indicated for use in pediatric patients. Clinical studies have not been conducted in the pediatric population. If estrogen is administered to patients whose bone growth is not complete, periodic monitoring of bone metabolism and effects on epiphyseal centers is recommended during estrogen administration. 8.5 Geriatric Use There have not been sufficient numbers of geriatric women involved in clinical studies utilizing Climara to determine whether those over 65 years of age differ from younger subjects in their response to Climara. The Women’s Health Initiative Studies In the WHI estrogen-alone substudy (daily CE [0.625 mg]-alone versus placebo), there was a higher relative risk of stroke in women greater than 65 years of age [see Clinical Studies ( 14.3 )] . 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 Clinical Studies ( 14.3 )] . 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-alone or estrogen plus progestin when compared to placebo [see Warnings and Precautions ( 5.3 ), and Clinical Studies ( 14.4 )] . 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 ( 5.3 ), and Clinical Studies ( 14.4 )] .

Boxed warning
Information about contraindications or serious warnings, particularly those that may lead to death or serious injury.WARNING: ENDOMETRIAL CANCER, CARDIOVASCULAR DISORDERS, PROBABLE DEMENTIA and BREAST CANCER 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 ( 5.2 )] . Cardiovascular Disorders and Probable Dementia The Women’s Health Initiative (WHI) estrogen-alone substudy reported increased risks of stroke and deep vein thrombosis (DVT) in postmenopausal women (50 to 79 years of age) during 7.1 years of treatment with daily oral conjugated estrogens (CE) [0.625 mg]-alone, relative to placebo [see Warnings and Precautions ( 5.1 ), and Clinical Studies ( 14.3 )] . The WHI Memory Study (WHIMS) estrogen-alone ancillary study of the 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 ( 5.3 ), Use in Specific Populations ( 8.5 ), and Clinical Studies ( 14.4 )] . Do not use estrogen-alone therapy for the prevention of cardiovascular disease or dementia [see Warnings and Precautions ( 5.1 , 5.3 ), and Clinical Studies ( 14.3 , 14.4 )] . 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. Estrogen Plus Progestin Therapy Cardiovascular Disorders and Probable Dementia The WHI estrogen plus progestin substudy reported increased risks of 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 CE (0.625 mg) combined with medroxyprogesterone acetate (MPA) [2.5 mg], relative to placebo [see Warnings and Precautions ( 5.1 ), and Clinical Studies ( 14.3 )] . The WHIMS estrogen plus progestin ancillary study of the 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 ( 5.3 ), Use in Specific Populations ( 8.5 ), and Clinical Studies ( 14.4 )] . Do not use estrogen plus progestogen therapy for the prevention of cardiovascular disease or dementia [see Warnings and Precautions ( 5.1 , 5.3 ), and Clinical Studies ( 14.3 , 14.4 )] . Breast Cancer The WHI estrogen plus progestin substudy also demonstrated an increased risk of invasive breast cancer [see Warnings and Precautions ( 5.2 ), and Clinical Studies ( 14.3 )] . Only daily oral 0.625 mg CE and 2.5 mg MPA were studied in the estrogen plus progestin substudy of the 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 progestogen 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 progestogen 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.
