ANNOVERA

ANNOVERA (segesterone acetate and ethinyl estradiol vaginal system) is a toroidal- shaped (ring), nonbiodegradable, flexible, opaque white vaginal system containing two active components, a progestin, segesterone acetate, and an estrogen, ethinyl estradiol. When placed in the vagina, each ANNOVERA releases an approximate average 0.15 mg/day of segesterone acetate and 0.013 mg/day of ethinyl estradiol over the 21 days in-use period of each cycle for up to 13 cycles (total of 273 days). Each cycle is 28 days, with 21 days in and 7 days out. The inactive ingredients are dibutyltin dilaurate, silicone elastomers, silicone medical adhesive, and titanium dioxide. The elastomers are all methyl siloxane-based polymers. The vaginal system body has an overall diameter of 56 mm and a cross-sectional diameter of 8.4 mm. It contains two channels of approximately 3.0 mm diameter and 27 mm length into which steroid-containing cores are inserted. Each ANNOVERA contains 103 mg of SA distributed throughout both cores and 17.4 mg of EE distributed throughout only one core. The core containing 40% SA and 12% EE of its mass is 3 mm in diameter and 18 mm in length. The core containing 50% SA of its mass is 3 mm in diameter and 11 mm in length. Contact between the cores and the vaginal system body is fixed by coating the channels with silicone medical adhesive before introducing the cores. After insertion of the cores, the channels are sealed with the silicone medical adhesive. The structural formulas, and properties for the active components are shown below: STRUCTURAL FORMULAS: Segesterone Acetate (SA) Ethinyl Estradiol (EE) PROPERTIES: Established Name: Segesterone Acetate Chemical Name: 16-methylene-17α-acetoxy-19-nor-pregn-4-ene-3,20-dione Molecular Formula: C 23 H 30 O 4 Molecular Weight: 370.5 Physical Form: White, or yellowish white powder Solubility: Slightly soluble in n-hexane, soluble in ethyl acetate and methanol, freely soluble in acetone (USP classification) Melting Point: 173°C–177°C Established Name: Ethinyl Estradiol Chemical Name: 19-Nor-17α -pregna-1,3,5(10)-trien-20-yne-3,17-diol Molecular Formula: C 20 H 24 O 2 Molecular Weight: 296.4 Physical Form: White to slightly ye ll owish-white crysta ll ine powder Solubility: Practically insoluble in water, freely soluble in alcohol, it dissolves in alkaline solution Melting Point: 181°C–185°C The steroids diffuse out of the vaginal system with release rates that vary over time. Based on in vitro data, the daily release rates of SA and EE are higher during each initial 24–48 hours of use achieving a somewhat lower steady-state with continued use over the subsequent days in each cycle. The vaginal system is designed to be used for 13 cycles (1 year) on a 21/7 days in/out schedule. The total in-use time with the 21/7 days in/out schedule over 13 cycles is 273 days. Based on the residual amount of drug in vaginal systems used in clinical trials over 13 cycles, a total of 41.3 mg of SA and 3.4 mg of EE are released over this period. This translates to an approximate average daily dose of 0.15 mg of segesterone acetate and 0.013 mg of ethinyl estradiol with higher release rate expected at the beginning of dosing and a lower release rate toward the end.

ANNOVERA is indicated for use by females of reproductive potential to prevent pregnancy. ANNOVERA is a progestin/estrogen CHC indicated for use by females of reproductive potential to prevent pregnancy. ( 1 ) Limitations of Usage Not adequately evaluated in females with a body mass index of >29 kg/m 2 . ( 1 ) Limitations of Use ANNOVERA has not been adequately studied in females with a BMI >29 kg/m 2 .

One ANNOVERA is inserted in the vagina. The vaginal system must remain in place continuously for 3 weeks (21 days) followed by a 1-week (7-day) vaginal system-free interval. One vaginal system provides contraception for thirteen 28-day cycles (1 year). ( 2 ) 2.1 How to Use ANNOVERA Instruct patients that ANNOVERA should be used as directed [see How to Start ANNOVERA (2.2) ] . One ANNOVERA should be placed in the vagina. For maximum contraceptive effectiveness, ANNOVERA is to remain in the vagina continuously for 21 days (3 complete weeks). It is removed for a 1-week dose-free interval, and during this time a withdrawal bleed usually occurs. The removed vaginal system should be cleaned with mild soap and warm water, patted dry with a clean cloth towel or paper towel, and placed in its case during the 1-week dose- free interval. At the end of the dose-free interval, the vaginal system should be cleaned prior to being placed back in the vagina for another 21 continuous days (3 complete weeks). This pattern of ANNOVERA use made up of 3-weeks in and 1-week out is a cycle of use; one ANNOVERA vaginal system will provide contraception for 13 cycles. With clean hands, the user can choose an insertion position that is comfortable, such as lying down, squatting, or standing. The sides of the vaginal system are pressed together for insertion into the vagina. When properly inserted, the vaginal system should be entirely in the vagina and behind the pelvic bone. The day and time of insertion should be noted so that the vaginal system can be removed 3 weeks later on the same day and at about the same time. ANNOVERA can be removed by hooking an index finger into the vaginal system inside the vagina and gently pulling the vaginal system. For patient instructions regarding cleaning the vaginal system, see FDA-approved Patient Information . 2.2 How to Start ANNOVERA IMPORTANT: Consider the possibility of ovulation and conception prior to the first use of ANNOVERA. No Hormonal Contraceptive Use in the Preceding Cycle and after Copper IUD Removal : The woman should insert ANNOVERA between days 2 and 5 of her regular menstrual bleeding; no back-up contraception is needed. If menstrual cycles are irregular or if the start is more than 5 days from the last menstrual bleeding, the woman should use an additional barrier method during coitus, such as a male condom or spermicide, for the first 7 days of ANNOVERA use. Switching from a CHC: A woman who has been using her CHC method consistently and correctly, and who you are reasonably certain is not already pregnant, may switch from her previous CHC to ANNOVERA on any day of the CHC cycle (Day 1-28), without the need for back-up contraception, but no more than 7 hormone-free days should occur before starting ANNOVERA. Switching from a Progestin-Only Method [Progestin-only pills (POP), Progestin Injection, Progestin Implant, Progestin Intrauterine System (IUS)]: If a woman has no contraindications to the use of ethinyl estradiol (EE), she may elect to switch from a progestin-only method to ANNOVERA. If switching from progestin-only pills, she should begin ANNOVERA at the time she would have taken her next POP pill. If switching from an injection, she should begin ANNOVERA at the time of her next scheduled injection. If switching from an implant or an IUS, she should begin ANNOVERA at the time of implant or IUS removal. In all of these cases, the woman should use an additional barrier method during coitus, such as a male condom or spermicide, for the first 7 days of ANNOVERA use. Use after Abortion or Miscarriage: If a woman has no contraindications to the use of EE, ANNOVERA may be initiated for contraception within the first 5 days following a complete first trimester abortion or miscarriage without additional back-up contraception. If more than 5 days have elapsed from the first trimester abortion or miscarriage, then follow the instructions for "No Hormonal Contraceptive Use in the Preceding Cycle" and a barrier method should be used from the time of the first trimester abortion or miscarriage to the initiation of ANNOVERA. ANNOVERA should not be started earlier than 4 weeks after a second trimester abortion or miscarriage due to the increased risk of thromboembolism [see Contraindications (4) and Warnings and Precautions (5.1) ] . Following Childbirth: ANNOVERA should not be started sooner than 4 weeks postpartum and only in females who choose not to breastfeed. Prior to 4 weeks postpartum there is an increased risk of thromboembolism [see Contraindications (4) and Warnings and Precautions (5.1) ] . The initiation of ANNOVERA 4 weeks or more postpartum should be accompanied by an additional method of contraception during coitus, such as male condoms or spermicide, for the first 7 days if the woman has not yet had a period. Consider the possibility of ovulation and conception occurring prior to initiating ANNOVERA. Females who are breastfeeding should not use ANNOVERA until after weaning. 2.3 Deviations from the Recommended Regimen Contraceptive efficacy of ANNOVERA may be reduced if a woman deviates from the recommended use. ANNOVERA should remain in the vagina for a continuous period of 21 days (3 weeks); then ANNOVERA should be taken out of the vagina for 7 days. In a 28-day cycle, a deviation that involves ANNOVERA being out of the vagina for less than 7 days will not increase pregnancy risk. In a 28-day cycle, a deviation that involves ANNOVERA being out of the vagina for more than 7 days will increase pregnancy risk and back-up contraception is recommended in these instances. Deviations from the recommended regimen may result in a new vaginal system change day [See FDA- approved Patient Information ]. Inadvertent Removal or Expulsion ANNOVERA can be accidently expelled. Accidental expulsion could occur while removing a tampon, during coitus, or with straining during a bowel movement. If the vaginal system is accidentally expelled once during the 21 days of intravaginal use and is replaced within 2 hours, contraceptive efficacy should not be reduced and no back-up contraception is needed. If the vaginal system is accidently expelled, wash it with mild soap and warm water, rinse and pat dry with a clean cloth towel or paper towel, and replace it as soon as possible. During the 21 days of continuous use, if ANNOVERA is out of the vagina for more than 2 continuous hours or more than 2 cumulative hours (multiple inadvertent removals or expulsions adding up to 2 hours), then back-up contraception, such as male condoms or spermicide, should be used until the vaginal system has been in the vagina for 7 consecutive days. The use of combined hormonal contraceptives (those containing an estrogen) for emergency contraception during use of ANNOVERA is not recommended. Prolonged Vaginal System Free Interval If the vaginal system free interval is prolonged, consider the possibility of pregnancy and have the woman use back-up contraception, such as male condoms or spermicide, during coitus until the vaginal system has been in the vagina for 7 consecutive days. The use of combined hormonal contraceptives (those containing an estrogen) for emergency contraception during use of ANNOVERA is not recommended. Prolonged Use of ANNOVERA If ANNOVERA is left in the vagina for more than 21 days, it should be removed for 7 days and then reinserted for 21 days to resume a 21/7 schedule.

ANNOVERA is contraindicated in females who are known to have or develop the following conditions: A high risk of arterial or venous thrombotic diseases.

The clinical trials that evaluated the safety of ANNOVERA were obtained from three 13- cycle trials. One trial was conducted entirely in the U.S. (15 sites), and the other two were global studies that included 5 U.S. sites and 7 international sites (Australia, Brazil, Chile, Dominican Republic, Finland, Hungary, Sweden). All three trials were open label and enrolled healthy females, desiring contraception, 18 to 40 years of age. At about 50% enrollment, females with BMI >29 kg/m 2 were excluded due to the occurrence of two VTEs in this subgroup. In total, 2,308 females contributed 21,590 cycles of exposure for safety evaluation and 999 completed 13 cycles; there were 209 subjects with BMI >29 kg/m 2 who contributed 1,254 cycles of exposure with 36 subjects completing 13 cycles. The demographic profile for subjects was: mean age 26.7 years, mean BMI 24.1 (16.0- 41.5) kg/m 2 ; 67% were from the U.S. The racial distribution was 71% Caucasian, 14% African American, 4% Asian, and 11% Other; 30% of the population was Hispanic. Most Common Adverse Reactions Table 1 summarizes the most common adverse reactions reported by females using ANNOVERA. This table shows adverse reactions reported in at least 5% of subjects. In addition, 25% of subjects reported at least 1 complete expulsion during their use of ANNOVERA. Table 1: Adverse Drug Reactions Reported by ≥ 5% of ANNOVERA-treated Subjects Adverse Reactions % (N=2,308) Headache, including migraine 38.6 Nausea/vomiting 25.0 Vulvovaginal mycotic infection/vaginal candidiasis 14.5 Abdominal pain/lower/upper 13.3 Dysmenorrhea 12.5 Vaginal discharge 11.8 UTI/cystitis/pyelonephritis/genitourinary tract infection 10.0 Breast pain/tenderness/discomfort 9.5 Metrorrhagia/menstrual disorder 7.5 Diarrhea 7.2 Genital pruritus 5.5 Adverse Reactions Leading to Discontinuation Among subjects using ANNOVERA for contraception, 12% discontinued from the clinical trials due to an adverse reaction. Table 2 summarizes the most common adverse reactions leading to discontinuation. In addition, 1.4% of subjects discontinued ANNOVERA use due to vaginal system expulsions. Table 2: Adverse Reactions Leading to Discontinuation by ≥ 1% of ANNOVERA treated Subjects Adverse Reactions % (N=2,308) Metrorrhagia/menorrhagia 1.7 Headache, including migraine 1.3 Vaginal discharge/vulvovaginal mycotic infections 1.3 Nausea/vomiting 1.2 Serious Adverse Reactions Serious adverse reactions occurring in ≥2 subjects were: VTEs (deep venous thrombosis, cerebral vein thrombosis, pulmonary embolism); psychiatric events; drug hypersensitivity reactions; and spontaneous abortions. 6.2 Postmarketing Experience Five studies that compared breast cancer risk between ever-users (current or past use) of COCs and never-users of COCs reported no association between ever use of COCs and breast cancer risk, with effect estimates ranging from 0.90 - 1.12 (Figure 2). Three studies compared breast cancer risk between current or recent COC users (<6 months since last use) and never users of COCs (Figure 2). One of these studies reported no association between breast cancer risk and COC use. The other two studies found an increased relative risk of 1.19 - 1.33 with current or recent use. Both of these studies found an increased risk of breast cancer with current use of longer duration, with relative risks ranging from 1.03 with less than one year of COC use to approximately 1.4 with more than 8-10 years of COC use. Figure 2: Relevant Studies of Risk of Breast Cancer with Combined Oral Contraceptives RR = relative risk; OR = odds ratio; HR = hazard ratio. "ever COC" are females with current or past COC use; "never COC use" are females who never used COCs. Figure 2

The sections below provide information on substances for which data on drug interactions with CHCs are available. There is little information available about the clinical effect of most drug interactions that may affect ANNOVERA. However, based on the known pharmacokinetic effects of these drugs, clinical strategies to minimize any potential adverse effect on contraceptive effectiveness or safety are suggested. Consult the approved product labeling of all concurrently used drugs to obtain further information about interactions with ANNOVERA or the potential for metabolic enzyme or transporter system alterations. Drugs or herbal products that induce certain enzymes, including CYP3A4, may decrease the effectiveness of ANNOVERA or increase breakthrough bleeding. Counsel patients to use a back-up or alternative method of contraception when enzyme inducers are used with ANNOVERA. ( 7.1 ) 7.1 Effects of Other Drugs on Combined Hormonal Contraceptives Substances Decreasing the Systemic Exposure of CHCs and Potentially Diminishing the Efficacy of ANNOVERA : Table 3 includes substances that demonstrated an important drug interaction with CHCs. Table 3: Significant Drug Interactions Involving Substances That Decrease Systemic Exposure of CHCs Metabolic Enzyme Inducers Clinical effect Concomitant use of CHCs with metabolic enzyme inducers may decrease the systemic concentrations of the estrogen and/or progestin component of CHCs [see Clinical Pharmacology (12.3) ] . Decreased exposure of the estrogen and/or progestin component of CHCs may potentially diminish the effectiveness of CHCs and may lead to contraceptive failure or an increase in breakthrough bleeding. Prevention or management Counsel females to use an alternative method of contraception or a back-up method when enzyme inducers are used with CHCs. Continue back-up contraception for 28 days after discontinuing the enzyme inducer to maintain contraceptive reliability. Examples Aprepitant, barbiturates, bosentan, carbamazepine, efavirenz, felbamate, griseofulvin, oxcarbazepine, phenytoin, rifampin, rifabutin, rufinamide, topiramate, products containing St. John's wort Induction potency of St. John's wort may vary widely based on preparation. , and certain protease inhibitors (see separate section on protease inhibitors below). Substances Increasing the Systemic Exposure of CHCs and Potentially Increasing Exposure to Estrogen and/or Progestin in ANNOVERA : Co- administration of atorvastatin or rosuvastatin and certain CHCs containing EE increase systemic exposure of EE by approximately 20–25%. Ascorbic acid and acetaminophen may increase plasma EE concentrations, possibly by inhibition of conjugation. CYP3A4 inhibitors such as itraconazole, voriconazole, fluconazole, grapefruit juice, or ketoconazole may increase systemic exposure of the estrogen and/or progestin component of ANNOVERA. Human Immunodeficiency Virus (HIV)/ Hepatitis C Virus (HCV) Protease Inhibitors and Non-nucleoside Reverse Transcriptase Inhibitors : Significant decreases in systemic exposure of estrogen and/or progestin have been noted when CHCs are co-administered with some HIV protease inhibitors (eg, nelfinavir, ritonavir, darunavir/ritonavir, (fos)amprenavir/ritonavir, lopinavir/ritonavir, and tipranavir/ritonavir), some HCV protease inhibitors (eg, boceprevir and telaprevir), and some non-nucleoside reverse transcriptase inhibitors (eg, nevirapine). In contrast, significant increases in systemic exposure of estrogen and/or progestin have been noted when CHCs are co-administered with certain other HIV protease inhibitors (eg, indinavir and atazanavir/ritonavir) and with other non-nucleoside reverse transcriptase inhibitors (eg, etravirine). 7.2 Effects of Combined Hormonal Contraceptives on Other Drugs Table 4 provides significant drug interaction information for drugs co-administered with CHCs. Table 4: Significant Drug Interaction Information for Drugs Co-Administered with CHCs Lamotrigine Clinical effect Concomitant use of CHCs with lamotrigine may significantly decrease systemic exposure of lamotrigine due to induction of lamotrigine glucuronidation. Prevention or management Dose adjustment for lamotrigine may be necessary. Consult the approved product labeling for lamotrigine. Thyroid Hormone Replacement Therapy or Corticosteroid Replacement Therapy Clinical effect Concomitant use of CHCs with thyroid hormone replacement therapy or corticosteroid replacement therapy may increase systemic exposure of thyroid-binding and cortisol-binding globulin [see Warnings and Precautions (5.12) ] . Prevention or management The dose of replacement thyroid hormone or cortisol therapy may need to be increased. Consult the approved product labeling for the therapy in use [see Warnings and Precautions (5.12) ] . Other Drugs Clinical effect Concomitant use of CHCs may decrease systemic exposure of acetaminophen, morphine, salicylic acid, and temazepam. Concomitant use with ethinyl estradiol-containing CHCs may increase systemic exposure of other drugs (eg, cyclosporine, prednisolone, theophylline, tizanidine, and voriconazole). Prevention or management The dosage of drugs that can be affected by this interaction may need to be increased or decreased. Consult the approved product labeling for the concomitantly used drug. 7.3 Use of Vaginal Products with ANNOVERA In a drug-drug interaction study with ANNOVERA and the concurrent use of three different formulations of vaginal miconazole, the use of water-based vaginal miconazole cream resulted in no change in exposure to EE or SA from the vaginal system. However, the use of either the 1- day or the 3-day oil-based miconazole suppository was associated with an overall increase in exposure up to 67% for EE and 32% for SA. Considering the potential long-term effect on vaginal system performance, concurrent use of oil-based vaginal suppositories should not occur with ANNOVERA use. If there is a need to treat a vaginal condition, water-based vaginal cream or oral therapy may be used concurrently with the vaginal system [see Clinical Pharmacology (12.3) ] . Lubricants: Water-based vaginal lubricants have no effect on ANNOVERA; however, oil- based (including silicone-based) vaginal lubricants will alter the vaginal system and/or exposure to EE and SA and should not be used. ANNOVERA use is compatible with male condoms made with natural rubber latex, polyisoprene, and polyurethane. The effect of tampon use on the systemic exposure of SA and EE from ANNOVERA has not been studied. 7.4 Concomitant Use with HCV Combination Therapy – Liver Enzyme Elevation Do not co-administer ANNOVERA with HCV drug combinations containing ombitasvir/paritaprevir/ritonavir, with or without dasabuvir, due to potential for ALT elevations [see Contraindications (4) and Warnings and Precautions (5.3) ] . 7.5 Interference with Laboratory Tests The use of contraceptive steroids may influence the results of certain laboratory tests, such as coagulation factors, lipids, glucose tolerance, and binding proteins.

16.2 Storage Conditions Prior to dispensing ANNOVERA to the user, store ANNOVERA at 20°C to 25°C (68°F to 77°F), excursions permitted to 15°C to 30°C (59°F to 86°F) [see USP Controlled Room Temperature]. Protect ANNOVERA from direct sunlight. Do not refrigerate or freeze and avoid excessive heat.
