Adverse Reactions

6 ADVERSE REACTIONS The following serious adverse reactions are discussed elsewhere in the labeling: • Cardiovascular Disorders [see Boxed Warning, Warnings and Precautions (5.2)] • Malignant Neoplasms [see Boxed Warning, Warnings and Precautions (5.3)] The most common adverse reactions (incidence ≥5 percent) with Vagifem are: back pain, vulvovaginal pruritus, vulvovaginal mycotic infection and diarrhea. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Novo Nordisk at 1-888-824-4336 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. In a 12-month randomized, double-blind, parallel group, placebo-controlled study, a total of 309 postmenopausal women were randomized to receive either placebo or Vagifem 10 mcg inserts. Adverse reactions with an incidence of ≥5 percent in the Vagifem 10 mcg group and greater than those reported in the placebo group are listed in Table 1.

Description

11 DESCRIPTION Vagifem 10 mcg (estradiol vaginal inserts) are small, white, film-coated inserts containing 10.3 mcg of estradiol hemihydrate equivalent to 10 mcg of estradiol. Each insert of Vagifem 10 mcg contains the following excipients: hypromellose, lactose monohydrate, maize starch and magnesium stearate. The film coating contains hypromellose and polyethylene glycol. Each Vagifem insert is 6 mm in diameter and is placed in a disposable applicator. Each insert-filled applicator is packaged separately in a blister pack. Vagifem inserts are used intravaginally. When the insert comes in contact with the vaginal mucosa, estradiol is released into the vagina. Estradiol hemihydrate is a white, almost white or colorless crystalline solid, chemically described as estra-1,3,5 (10)-triene-3,17β-diol. The chemical formula is C 18 H 24 O 2 • ½ H 2 O with a molecular weight of 281.4. The structural formula is: Structural Formula for Vagifem

Dosage And Administration

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 with a history of endometriosis may need a progestogen [see Warnings and Precautions (5.3 , 5.15) ] . 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. Administer Vagifem intravaginally: • 1 insert daily for 2 weeks, followed by 1 insert twice weekly (for example, Tuesday and Friday) ( 2.1 ) 2.1 Treatment of Atrophic Vaginitis due to Menopause Administer Vagifem intravaginally using the supplied applicator: 1 insert daily for 2 weeks, followed by 1 insert twice weekly (for example, Tuesday and Friday).

Indications And Usage

1 INDICATIONS AND USAGE • Vagifem is an estrogen indicated for the treatment of atrophic vaginitis due to menopause ( 1.1 ) 1.1 Treatment of Atrophic Vaginitis due to Menopause

Overdosage

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

Drug Interactions

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 inhibitors of CYP3A4 may affect estrogen drug metabolism and decrease ot increase the estrogen plasma concentration. ( 7 )

Clinical Pharmacology

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, 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 concentration does not predict an individual woman’s therapeutic response to Vagifem 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 Estrogen drug products are well absorbed through the skin, mucous membranes, and the gastrointestinal tract. The vaginal delivery of estrogens circumvents first-pass metabolism. In a single-center, randomized, open-label, multiple-dose study conducted in 29 patients, Vagifem 10 mcg demonstrated a mean estradiol (E2) C ave at Day 83 of 5.5 pg/mL after 12 weeks of treatment (see Table 2). Table 2: Arithmetic Means of Estradiol (E2), Estrone (E1), and Estrone Sulfate (E1S) PK Parameters Following Multiple Doses Patients received vaginal inserts as a once daily intravaginal treatment for the first 2 weeks and a twice weekly intravaginal maintenance for the following 10 weeks. of Vagifem 10 mcg Uncorrected for baseline, N=29 E2 E1 E1S AUC 0-24 (h.pg/mL) C ave (0-24) (pg/mL) %CV CV: Coefficient of Variance for both AUC 0-24 and C ave(0-24) AUC 0-24 (h.pg/mL) C ave (0-24) (pg/mL) %CV AUC 0-24 (h.pg/mL) C ave (0-24) (pg/mL) %CV Day 1 242.08 10.09 33.02 485.21 20.22 44.86 5158.32 214.93 53.57 Day 14 176.49 7.35 43.69 496.14 20.67 30.88 6323.41 263.48 50.07 Day 83 132.04 5.50 59.69 411.08 17.13 39.58 3804.65 158.53 49.76 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 the 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 portion 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.

INSTRUCTIONS FOR USE Vagifem (Va-juh-fem) (estradiol vaginal insert) Read this Patient Information before you start using Vagifem and read what you get each time you refill your Vagifem prescription. 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. Step 1: Tear off a single applicator. Step 2: Separate the plastic wrap and remove the applicator from the plastic wrap as shown in Figure A. If after opening the package you see that the insert has come out of the applicator but has not fallen out of the package, carefully put it back into the applicator for insertion. Please keep your hands clean and dry while handling the insert. Figure A Step 3: Hold the applicator so that the finger of one hand can press the applicator plunger as shown in Figure B. Figure B Step 4: Next select the best position for vaginal insertion of Vagifem (estradiol vaginal inserts) that is most comfortable for you. See suggested reclining Figure C or standing Figure D position illustrated below: Figure C Figure D Step 5: Using the other hand, guide the applicator gently and comfortably through the vaginal opening (see Figures C and D above). If prior to insertion the insert falls out of the applicator, throw the insert and applicator away and use a new insert-filled applicator. Step 6: The applicator should be inserted (without forcing) as far as comfortably possible, or until half of the applicator is inside your vagina, whichever is less. Step 7: Once the insert-filled applicator has been inserted, gently press the plunger until the plunger is fully depressed. This will eject the insert inside your vagina where it will dissolve slowly over several hours. Step 8: After depressing the plunger, gently remove the applicator and dispose of it the same way you would a plastic tampon applicator. The applicator is of no further use and should be discarded properly. Insertion may be done at any time of the day. It is advisable to use the same time daily for all applications of Vagifem (estradiol vaginal inserts). If you have any questions, please consult your healthcare provider or pharmacist.

What is the most important information I should know about Vagifem

(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 Vagifem. 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 65 years of age and older.
  • Do not use estrogens with progestogens to prevent heart disease, heart attack, strokes or dementia.
  • Using estrogens with progestogens may increase your chances of getting blood clots, strokes, heart attacks, or breast cancer.
  • Using estrogens with progestogens may increase your chance of getting dementia, based on a study of women 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 Vagifem will affect your chances of these conditions. You and your healthcare provider should talk regularly about whether you still need treatment with Vagifem.
  • What is Vagifem?

    Vagifem is a prescription medicine that contains estradiol (an estrogen hormone) in a vaginal insert.

    What is Vagifem used for?

    Vagifem is used after menopause to:

  • 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 Vagifem to control these problems.
  • Who should not use Vagifem?

    Do not start using Vagifem 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 chances 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 Vagifem.
  • had a stroke or heart attack
  • currently have or have had blood clots

  • These are not all the possible side effects of Vagifem. For more information, ask your healthcare provider or pharmacist. Tell your healthcare provider if you have any side effects the 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 Novo Nordisk at 1-888-824-4336.

    What can I do to lower my chances of a serious side effect with Vagifem?

  • Talk with your healthcare provider regularly about whether you should continue using Vagifem
  • 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 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 Vagifem.
  • 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 for getting heart disease.
  • How should I store Vagifem?

    Store Vagifem at room temperature 68ºF to 77ºF (20º C to 25ºC); excursions permitted to 59ºF to 86ºF (15ºC to 30ºC).

    Do not refrigerate.

    [see USP Controlled Room Temperature].

    Keep Vagifem out of the reach of children

    Clinical Studies

    14 CLINICAL STUDIES 14.1 Effects on Atrophic Vaginitis in Postmenopausal Women A 12-month double-blind, randomized, parallel group, placebo-controlled multicenter study was conducted in the U.S. and Canada to evaluate the efficacy and safety of Vagifem 10 mcg in the treatment of atrophic vaginitis in 309 postmenopausal women between 46 and 81 years of age (mean 57.6 years of age) who at baseline identified their most bothersome symptom of atrophic vaginitis from among six symptoms (vaginal dryness, vaginal and/or vulvar irritation/itching, vaginal soreness, dysuria, dyspareunia and vaginal bleeding associated with intercourse). Women inserted one insert intravaginally each day for 14 days, then one insert twice weekly for the remaining 50 weeks. The majority (92.9 percent) of the women were Caucasian (n=287), 3.2 percent were Black (n=10), 1.6 percent were Asian (n=5) and 2.2 percent were Other (n=7). All participants were assessed for improvement in the mean change from baseline to Week 12 for co-primary efficacy variables of: a composite of most bothersome symptoms of atrophic vaginitis; percentage of vaginal superficial cells and percentage of vaginal parabasal cells on a vaginal smear; and vaginal pH. Relief of Vaginal Symptoms Vagifem 10 mcg was statistically superior to placebo in reducing the severity of a composite score of most bothersome symptoms associated with atrophic vaginitis at Week 12 (see Table 3). Table 3: Mean Change from Baseline to Week 12 in a Composite Score of Most Bothersome Symptoms Compared to Placebo – ITT Population All randomized subjects who received at least one dose of study drug and had at least one post-baseline evaluation. Placebo Vagifem 10 mcg ITT Population N 93 190 Baseline mean composite score 2.29 2.35 Change from baseline at Week 12 (LOCF) -0.84 -1.20 p-value versus Placebo --- 0.002 Also demonstrated for Vagifem 10 mcg compared to placebo was a statistically significant increase in the percentage of superficial cells at Week 12 (13.2 percent compared to 3.8 percent for matching placebo, p<0.001), a statistically significant decrease in parabasal cells at Week 12 (-37.0 percent compared to -9.3 percent for matching placebo, p<0.001), and a statistically significant mean reduction between baseline and Week 12 in vaginal pH score (-1.3 compared to -0.4 for matching placebo, p<0.001). Endometrial safety was assessed by endometrial biopsy at the screening and final study visit. Of the 172 women in the Vagifem 10 mcg group who had a biopsy performed at end of study, 92 women had endometrial tissue that was atrophic or inactive and 73 women had no tissue or tissue insufficient for diagnosis. There was one case of adenocarcinoma grade 2 and one case of complex hyperplasia without atypia. Three women exhibited polyps (two atrophic polyps and one adenomyomatus type polyp) and two others had adenomyosis and an atypical epithelial proliferation. Endometrial safety of Vagifem 10 mcg was additionally evaluated in a second, 12 month, open-label, multicenter safety study. Of the 297 women who had a biopsy performed at end of study, 183 women had endometrial tissue that was atrophic or inactive and 111 women had no tissue or tissue insufficient for diagnosis. There was one case of complex hyperplasia without atypia. Two women exhibited polyps. 14.2 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 risks 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. Table 4: Relative and Absolute Risk Seen in the Estrogen-Alone Substudy of WHI Adapted from numerous WHI publications. WHI publications can be viewed at www.nhlbi.nih.gov/whi .

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-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 50-59 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 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 5. These results reflect centrally adjudicated data after an average follow-up of 5.6 years.

The WHI estrogen plus progestin substudy stratified by age showed in women 50-59 years of age, a non-significant trend toward reduced risk for overall mortality [HR 0.69 (95 percent CI, 0.44-1.07)]. 14.3 Women’s Health Initiative Memory Study The WHIMS estrogen-alone ancillary study of WHI enrolled 2,947 predominately 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 this 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 (5.4) , and Use in Specific Populations (8.5) ] . 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; 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 per 10,000 women-years. Probable dementia as defined in this 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 (5.4) , and Use in Specific Populations (8.5) ] . When data from the two populations were pooled as planned in the WHIMS protocol, the reported overall 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 (5.4) , and Use in Specific Populations (8.5) ] .

    Geriatric Use

    8.5 Geriatric Use There have not been sufficient numbers of geriatric women involved in clinical studies utilizing Vagifem to determine whether those over 65 years of age differ from younger subjects in their response to Vagifem. 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 (14.2) ] . 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 (14.2) ] . 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 (5.4) , and Clinical Studies (14.3) ]. 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 (14.3) ] .

    Pediatric Use

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

    Pregnancy

    8.1 Pregnancy Risk Summary Vagifem is not indicated for use in pregnancy. There are no data with the use of Vagifem 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

    8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Risk Summary Vagifem is not indicated for use in pregnancy. There are no data with the use of Vagifem 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 females. 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 Vagifem and any potential adverse effects on the breastfed child from Vagifem or from the underlying maternal condition. 8.4 Pediatric Use Vagifem 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 Vagifem to determine whether those over 65 years of age differ from younger subjects in their response to Vagifem. 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 (14.2) ] . 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 (14.2) ] .

    Boxed Warning

    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 ( 5.3 )]. 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 ( 5.2 ), and Clinical Studies ( 14.2 )]. The WHI Memory Study (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 ( 14.3 )]. Do not use estrogen-alone therapy for the prevention of cardiovascular disease or dementia [see Warnings and Precautions ( 5.2 , 5.4 ), and Clinical Studies ( 14.2 , 14.3 )]. 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 pulmonary embolism (PE), DVT, 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 ( 5.2 ), and Clinical Studies ( 14.2 )]. 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 ( 5.4 ), Use in Specific Populations ( 8.5 ), and Clinical Studies ( 14.3 )]. Do not use estrogen plus progestogen therapy for the prevention of cardiovascular disease or dementia [see Warnings and Precautions ( 5.2 , 5.4 ), and Clinical Studies ( 14.2 , 14.3 )]. 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 ( 14.2 )]. 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.
