Description

11 DESCRIPTION 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)...

Dosage and Administration

2 DOSAGE AND ADMINISTRATION 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...

Side Effects (Adverse Reactions)

6 ADVERSE REACTIONS The following adverse reactions are described elsewhere in other sections of the labeling: Serious cardiovascular events and stroke [see Boxed Warning and Warnings and Precautions (5.1) ] Vascular events [see Warnings and Precautions (5.1) ] Liver disease [see Warnings and Precautions (5.2) ] The most common adverse reactions (>5%) are headache/migraine, nausea/vomiting, vulvovaginal mycotic infection/candidiasis, abdominal pain lower/upper, dysmenorrhea, vaginal discharge, urinary tract infection, breast tenderness/pain/discomfort, bleeding irregularities including metrorrhagia, diarrhea, genital pruritus. ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact Mayne Pharma at 1-844-825-8500 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trial 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 the rates in the clinical trials of another drug and may not reflect the rates observed in practice. 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...

Drug Interactions

7 DRUG INTERACTIONS 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...

Pregnancy and Breastfeeding

8.1 Pregnancy Risk Summary 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 CHCs 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 2–4% and 15–20%, respectively. Discontinue ANNOVERA if pregnancy occurs, because there is no reason to use CHCs during pregnancy. Data Human Data No studies have been conducted of the use of ANNOVERA in pregnant females.

Overdosage

10 OVERDOSAGE There have been no reports of serious ill effects from overdose of CHCs. Overdosage may cause withdrawal bleeding in females and nausea. In case of suspected overdose, all ANNOVERA vaginal systems should be removed and symptomatic treatment given.
