Kyleena
Levonorgestrel · Intrauterine Device · Intrauterine
Uses
Kyleena is indicated to prevent pregnancy for up to 5 years. Replace the system after 5 years if continued use is desired. Kyleena is a progestin-containing intrauterine system (IUS) indicated for prevention of pregnancy for up to 5 years. ( 1 )
Dosage and administration
• Release rate of levonorgestrel (LNG) is 17.5 mcg/day after 24 days and declines to 7.4 mcg/day after 5 years; Kyleena must be removed or replaced after 5 years. ( 2.1 )
• To be inserted by a trained healthcare provider using strict aseptic technique. Follow insertion instructions exactly as described. ( 2.2 )
• Patient should be re-examined and evaluated 4 to 6 weeks after insertion; then yearly or more often if clinically indicated. ( 2.3 ) 2.1 Dosing Over Time Kyleena contains 19.5 mg of levonorgestrel (LNG) released in vivo at a rate of approximately 17.5 mcg/day after 24 days. This rate decreases progressively to 9.8 mcg/day after 1 year and to 7.4 mcg/day after 5 years. The average in vivo release rate of LNG is approximately 12.6 mcg/day over the first year and 9.0 mcg/day over a period of 5 years . [See Clinical Pharmacology ( 12.3 ).] Kyleena must be removed by the end of the fifth year and can be replaced at the time of removal with a new Kyleena if continued contraceptive protection is desired. Kyleena can be physically distinguished from other intrauterine systems (IUSs) by the combination of the visibility of the silver ring on ultrasound and the blue color of the removal threads. Kyleena is supplied in a sterile package within an inserter that enables single-handed loading (see Figure 1). Do not open the package until required for insertion [see Description ( 11.2 )] . Do not use if the seal of the sterile package is broken or appears compromised. Use strict aseptic techniques throughout the insertion procedure [see Warnings and Precautions ( 5.3 )] . Kyleena and Inserter 2.2. Insertion Instructions
• Obtain a complete medical and social history to determine conditions that might influence the selection of a levonorgestrel-releasing intrauterine system (LNG IUS) for contraception . If indicated, perform a physical examination and appropriate tests for any forms of genital or other sexually transmitted infections. [See Contraindications ( 4 ) and Warnings and Precautions ( 5.10 ).] Because irregular bleeding/spotting is common during the first months of Kyleena use, exclude endometrial pathology (polyps or cancer) prior to the insertion of Kyleena in women with persistent or uncharacteristic bleeding [see Warnings and Precautions ( 5.8 )] .
• Follow the insertion instructions exactly as described to ensure proper placement and avoid premature release of Kyleena from the inserter. Once released, Kyleena cannot be re-loaded .
• Check expiration date of Kyleena prior to initiating insertion.
• Kyleena should be inserted by a trained healthcare provider. Healthcare providers should become thoroughly familiar with the insertion instructions before attempting insertion of Kyleena.
• Insertion may be associated with some pain and/or bleeding or vasovagal reactions (for example, syncope, bradycardia), or with seizure, especially in patients with a predisposition to these conditions. Consider administering analgesics prior to insertion. Timing of Insertion Table 1: When to Insert Kyleena Starting Kyleena in women not currently using hormonal or intrauterine contraception
• Insert Kyleena any time there is reasonable certainty that the woman is not pregnant. Consider the possibility of ovulation and conception prior to initiation of this product [see Contraindications ( 4 )].
• If Kyleena is inserted during the first seven days of the menstrual cycle or immediately after a first trimester abortion, back-up contraception is not needed.
• If Kyleena is not inserted during the first seven days of the menstrual cycle, a barrier method of contraception should be used, or the patient should abstain from vaginal intercourse for seven days to prevent pregnancy. Switching to Kyleena from an oral, transdermal or vaginal hormonal contraceptive
• Insert Kyleena at any time, including during the hormone-free interval of the previous method.
• If inserted during active use of the previous method, continue that method for 7 days after Kyleena insertion or until the end of the current treatment cycle.
• If the woman was using continuous hormonal contraception, discontinue that method seven days after Kyleena insertion. Switching to Kyleena from an injectable progestin contraceptive
• Insert Kyleena at any time; a non-hormonal back-up birth control (such as condoms or spermicide) should also be used for 7 days if Kyleena is inserted more than 3 months (13 weeks) after the last injection. Switching to Kyleena from a contraceptive implant or another IUS
• Insert Kyleena on the same day the implant or IUS is removed.
• Insert Kyleena at any time during the menstrual cycle. Inserting Kyleena after first trimester abortion or miscarriage
• Insert Kyleena immediately after a first-trimester abortion or miscarriage, unless it is a septic abortion [see Contraindications ( 4 )]. Inserting Kyleena after childbirth or second-trimester abortion or miscarriage
• Immediate insertion after childbirth or second-trimester abortion or miscarriage
• Insert Kyleena after removal of the placenta. Back-up contraception is not needed. [See Contraindications ( 4 ), Warnings and Precautions ( 5.5 , 5.6 ), Adverse Reactions ( 6.2 )]. Interval insertion following complete involution of the uterus
• Wait a minimum of 6 weeks or until the uterus is fully involuted before inserting Kyleena [see Warnings and Precautions ( 5.5 , 5.6) , Adverse Reactions ( 6.2 )].
• Insert Kyleena any time there is reasonable certainty the woman is not pregnant.
• If Kyleena is not inserted during the first 7 days of the menstrual cycle, a back-up method of contraception should be used, or the woman should abstain from vaginal intercourse for 7 days to prevent pregnancy [see Contraindications ( 4 ), Warnings and Precautions ( 5.2 )].
Dosage forms and strengths
Kyleena is a LNG-releasing IUS (a type of intrauterine device, or IUD) consisting of a T-shaped polyethylene frame with a steroid reservoir containing a total of 19.5 mg LNG.

Warnings and precautions
• Remove Kyleena if pregnancy occurs with Kyleena in place. If pregnancy occurs, there is increased risk of ectopic pregnancy including loss of fertility, pregnancy loss, septic abortion (including septicemia, shock and death), and premature labor and delivery. ( 5.1 , 5.2 )
• Group A streptococcal infection has been reported following insertion of LNG IUS; strict aseptic technique is essential during insertion. ( 5.3 )
• Before using Kyleena, consider the risks of PID. ( 5.4 )
• Uterine perforation may occur and may reduce contraceptive effectiveness or require surgery. Risk is increased if inserted in lactating women and may be increased if inserted in women with fixed retroverted uteri and postpartum. ( 5.5 )
• Partial or complete expulsion may occur, which can be unnoticed, leading to loss of contraceptive efficacy. ( 5.6 )
• Evaluate persistent enlarged ovarian follicles or ovarian cysts. ( 5.7 )
• Bleeding patterns become altered, may remain irregular and amenorrhea may ensue. ( 5.8 )
• Kyleena can be safely scanned with MRI only under certain conditions. ( 5.11 ) 5.1 Risk of Ectopic Pregnancy Evaluate women for ectopic pregnancy if they become pregnant with Kyleena in place because the likelihood of a pregnancy being ectopic is increased with Kyleena. Approximately one-half of pregnancies that occur with Kyleena in place are likely to be ectopic. Also consider the possibility of ectopic pregnancy in the case of lower abdominal pain, especially in association with missed menses or if an amenorrheic woman starts bleeding. The incidence of ectopic pregnancy in clinical trials with Kyleena, which excluded women with a history of ectopic pregnancy, was approximately 0.2% per year. The risk of ectopic pregnancy in women who have a history of ectopic pregnancy and use Kyleena is unknown. Women with a previous history of ectopic pregnancy, tubal surgery or pelvic infection carry a higher risk of ectopic pregnancy. Ectopic pregnancy may result in loss of fertility. 5.2 Risks with Intrauterine Pregnancy If pregnancy occurs while using Kyleena, remove Kyleena because leaving it in place may increase the risk of spontaneous abortion and preterm labor. Removal of Kyleena or probing of the uterus may also result in spontaneous abortion. In the event of an intrauterine pregnancy with Kyleena, consider the following: Septic abortion In patients becoming pregnant with an IUS in place, septic abortion—with septicemia, septic shock, and death—may occur. Continuation of pregnancy If a woman becomes pregnant with Kyleena in place and if Kyleena cannot be removed or the woman chooses not to have it removed, warn her that failure to remove Kyleena increases the risk of miscarriage, sepsis, premature labor and premature delivery. Advise her of isolated reports of virilization of the female fetus following local exposure to LNG during pregnancy with an LNG IUS in place [see Use in Specific Populations ( 8.1 )] . Follow her pregnancy closely and advise her to report immediately any symptom that suggests complications of the pregnancy. 5.3 Sepsis Severe infection or sepsis, including Group A streptococcal sepsis (GAS), have been reported following insertion of a LNG-releasing IUS. In some cases, severe pain occurred within hours of insertion followed by sepsis within days. Because death from GAS is more likely if treatment is delayed, it is important to be aware of these rare but serious infections. Aseptic technique during insertion of Kyleena is essential in order to minimize serious infections such as GAS. 5.4 Pelvic Infection Promptly examine users with complaints of lower abdominal or pelvic pain, odorous discharge, unexplained bleeding, fever, genital lesions or sores. Remove Kyleena in cases of recurrent endometritis or pelvic inflammatory disease, or if an acute pelvic infection is severe or does not respond to treatment. Pelvic Inflammatory Disease (PID) Kyleena is contraindicated in the presence of known or suspected PID or in women with a history of PID unless there has been a subsequent intrauterine pregnancy [see Contraindications ( 4 )] . IUDs have been associated with an increased risk of PID, most likely due to organisms being introduced into the uterus during insertion. In clinical trials, PID was observed in 0.5% of women overall and occurred more frequently within the first year and most often within the first month after insertion of Kyleena. Women at increased risk for PID PID is often associated with a sexually transmitted infection (STI), and Kyleena does not protect against STI. The risk of PID is greater for women who have multiple sexual partners, and also for women whose sexual partner(s) have multiple sexual partners. Women who have had PID are at increased risk for a recurrence or re-infection. In particular, ascertain whether the woman is at increased risk of infection (for example, leukemia, acquired immune deficiency syndrome [AIDS], intravenous drug abuse). Subclinical PID PID may be asymptomatic but still result in tubal damage and its sequelae. Treatment of PID Following a diagnosis of PID, or suspected PID, bacteriologic specimens should be obtained, and antibiotic therapy should be initiated promptly. Removal of Kyleena after initiation of antibiotic therapy is usually appropriate. 1 Actinomycosis Actinomycosis has been associated with IUDs. Remove Kyleena from symptomatic women and treat with antibiotics. The significance of actinomyces-like organisms on Pap smear in an asymptomatic IUD user is unknown, and so this finding alone does not always require Kyleena removal and treatment. When possible, confirm a Pap smear diagnosis with cultures. 5.5 Perforation Perforation (total or partial, including penetration/embedment of Kyleena in the uterine wall or cervix) may occur most often during insertion, although the perforation may not be detected until sometime later. The incidence of perforation during clinical trials was < 0.1%.

The data described below reflect exposure of 1,697 healthy 18 to 41-year-old women (mean age 27.8 ± 5.2 years) to Kyleena. These data come from two multi-center contraceptive trials: A phase 2 study with a 3-year duration was conducted in Europe enrolling generally healthy, 21 to 41-year old women; 217 subjects were exposed to Kyleena for one year and 174 completed three years. The data in this trial cover approximately 8,000 cycles of exposure. A phase 3 study with a 3-year duration and an optional extension of Kyleena use up to 5 years was conducted in the United States (US), Canada, Europe, and Latin America. The population was generally healthy, 18 to 35-year old women. A total of 1,208 subjects were exposed to Kyleena for at least one year; 707 women entered the optional extension phase after 3 years and 550 completed five years. The data in this trial cover approximately 60,000 cycles. In total for both studies, 1,425 subjects were exposed for at least 1 year, and 550 subjects completed 5 years of use. Of the total of 1,697 subjects exposed to Kyleena, 563 were from the US and 1,134 were from Europe, Canada and Latin America; 623 (37%) were nulliparous (mean age 24.6 ± 4.5 years) and 1,074 (63%) were parous (mean age 29.7 ± 4.7 years). Most women who received Kyleena were Caucasian (83%) or Black/African American (4.4%); 9.4% of women were of Hispanic ethnicity. The clinical trials had no upper or lower weight or body mass index (BMI) limit. Mean BMI of Kyleena subjects was 25.2 kg/m2 (range 15.2 – 57.6 kg/m2); 16% had a BMI ≥ 30 kg/m2, and 2.0% had a BMI ≥ 40 kg/m2. The frequencies of reported adverse drug reactions represent crude incidences. The most common adverse reactions (occurring in ≥ 5% users) were vulvovaginitis (24%), ovarian cyst (22%), abdominal pain/pelvic pain (21%), headache/migraine (15%), acne/seborrhea (15%), dysmenorrhea/uterine spasm (10%), breast pain/breast discomfort (10%), and increased bleeding (8%). In the combined studies, 22% discontinued prematurely due to an adverse reaction. The most common adverse reactions (>1%) leading to discontinuation were increased bleeding (4.5%), abdominal pain/pelvic pain (4.2%), device expulsion (3.1%), acne/seborrhea (2.3%), and dysmenorrhea/uterine spasm (1.3%). Common adverse reactions (occurring in ≥1% users) are summarized in Table 4 (presented as crude incidences). Table 4: Adverse reactions that occurred in at least 1% of Kyleena users in clinical trials by System Organ Class (SOC) System Organ Class Adverse Reaction Incidence (%) (N=1,697) Reproductive System and Breast Disorders Vulvovaginitis 24.3 Ovarian cyst a 22.2 Dysmenorrhea/uterine spasm 8.0/2.4 Increased bleeding b 7.9 Breast pain/discomfort 7.1/3.5 Genital discharge 4.5 Device expulsion (complete and partial) 3.5 Upper genital tract infection 1.5 Gastrointestinal Disorders Abdominal pain/pelvic pain 13.3/8.2 Nausea 4.7 Skin and Subcutaneous Tissue Disorders Acne/Seborrhea 14.1/1.8 Alopecia 1.0 Nervous System Disorders Headache/Migraine 12.9/3.3 Psychiatric Disorders Depression/ Depressed mood 4.4/0.2 a Ovarian cysts were reported as adverse events if they were abnormal, non-functional cysts and/or had a diameter >3 cm on ultrasound examination b Not all bleeding alterations were captured as adverse reactions [see Warnings and Precautions ( 5.8 )] . In the clinical trials, serious adverse reactions occurring in more than a single subject included: ectopic pregnancy/ruptured ectopic pregnancy (10 subjects); pelvic inflammatory disease (6 subjects); missed abortion/incomplete spontaneous abortion/spontaneous abortion (4 subjects); ovarian cyst (3 subjects); abdominal pain (4 subjects); depression/affective disorder (4 subjects); and uterine perforation/embedded device (myometrial perforation) (3 subjects). 6.2 Postmarketing Experience Adverse Reactions from Postmarketing Spontaneous Reports The following adverse reactions have been identified during post-approval use of LNG-releasing IUSs. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Drug interactions
No drug-drug interaction studies have been conducted with Kyleena. Drugs or herbal products that induce or inhibit LNG metabolizing enzymes, including CYP3A4, may decrease or increase, respectively, the serum concentrations of LNG during the use of Kyleena. However, the contraceptive effect of Kyleena is mediated via the direct release of LNG into the uterine cavity and is unlikely to be affected by drug interactions via enzyme induction or inhibition.
Use in specific populations
8.1 Pregnancy Risk Summary The use of Kyleena is contraindicated in pregnancy or with a suspected pregnancy and Kyleena may cause adverse pregnancy outcomes [see Contraindications ( 4 ), Warnings and Precautions ( 5.1 , 5.2 )]. If a woman becomes pregnant with Kyleena in place, the likelihood of ectopic pregnancy is increased and there is an increased risk of miscarriage, sepsis, premature labor, and premature delivery . Remove Kyleena, if possible, if pregnancy occurs in a woman using Kyleena. If Kyleena cannot be removed, follow the pregnancy closely [see Warnings and Precautions ( 5.1 , 5.2 )] . There have been isolated cases of virilization of the external genitalia of the female fetus following local exposure to LNG during pregnancy with an LNG IUS in place. Animal reproduction studies have not been conducted with Kyleena. 8.2 Lactation Risk Summary Published studies report the presence of LNG in human milk. Small amounts of progestins (approximately 0.1% of the total maternal doses) were detected in the breast milk of nursing mothers who used other LNG-releasing IUSs, resulting in exposure of LNG to the breastfed infants. There are no reports of adverse effects in breastfed infants with maternal use of progestin-only contraceptives. Isolated cases of decreased milk production have been reported with a LNG-releasing IUS. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Kyleena and any potential adverse effects on the breastfed child from Kyleena or from the underlying maternal condition. 8.3 Females and Males of Reproductive Potential Return to Fertility After Discontinuing Kyleena About 71% of 163 women who desired pregnancy after study discontinuation and provided follow-up information, conceived within 12 months after removal of Kyleena. 8.4 Pediatric Use Safety and efficacy of Kyleena have been established in women of reproductive age. Efficacy is expected to be the same for postpubertal females under the age of 18 as for users 18 years and older. Use of this product before menarche is not indicated. 8.5 Geriatric Use Kyleena has not been studied in women over age 65 and is not approved for use in this population.

Description
Kyleena (levonorgestrel-releasing intrauterine system) contains 19.5 mg of LNG, a progestin, and is intended to provide an initial release rate of approximately17.5 mcg/day of LNG after 24 days. Levonorgestrel USP, (-)-13-Ethyl-17-hydroxy-18,19-dinor-17α-pregn-4-en-20-yn-3-one, the active ingredient in Kyleena, has a molecular weight of 312.4, a molecular formula of C 21 H 28 O 2 , and the following structural formula: 11.1 Kyleena Kyleena consists of a T-shaped polyethylene frame (T-body) with a steroid reservoir (hormone elastomer core) around the vertical stem. The white T-body has a loop at one end of the vertical stem and two horizontal arms at the other end. The reservoir consists of a whitish or pale yellow cylinder, made of a mixture of LNG and silicone (polydimethylsiloxane), containing a total of 19.5 mg LNG. The reservoir is covered by a semi-opaque silicone membrane, composed of polydimethylsiloxane and colloidal silica. A ring composed of 99.95% pure silver is located at the top of the vertical stem close to the horizontal arms and is visible by ultrasound. The polyethylene of the T-body is compounded with barium sulfate, which makes it radiopaque. A monofilament blue polypropylene removal thread is attached to a loop at the end of the vertical stem of the T-body. The polypropylene of the removal thread contains <0.5% phthalocyaninato(2-) copper as a colorant (see Figure 10). The components of Kyleena, including its packaging, are not manufactured using natural rubber latex. Figure 10. Kyleena Kyleena 11.2 Inserter Kyleena is packaged sterile within an inserter. The inserter (Figure 11), which is used for insertion of Kyleena into the uterine cavity, consists of a symmetric two-sided body and slider that are integrated with flange, lock, pre-bent insertion tube and plunger. The outer diameter of the insertion tube is 3.8 mm. The vertical stem of Kyleena is loaded in the insertion tube at the tip of the inserter. The arms are pre-aligned in the horizontal position. The removal threads are contained within the insertion tube and handle. Once Kyleena has been placed, the inserter is discarded. Figure 11. Diagram of Inserter Inserter Chem Diagram
Mechanism of action
12.1 Mechanism of Action The local mechanism by which continuously released LNG contributes to the contraceptive effectiveness of Kyleena has not been conclusively demonstrated. Studies of Kyleena and similar LNG IUS prototypes have suggested several mechanisms that prevent pregnancy: thickening of cervical mucus preventing passage of sperm into the uterus, inhibition of sperm capacitation or survival, and alteration of the endometrium .
