The recommended dosage of NEXTSTELLIS is one tablet daily for 28 consecutive days: one pink active tablet daily during the first 24 days followed by one white inactive tablet daily during the 4 following days . Table 1 NEXTSTELLIS Administration Instructions Starting NEXTSTELLIS in females with no current use of hormonal contraception Important: In females with irregular menstrual cycles, pregnancy testing may be necessary prior to initiation of this product. Day 1 Start : Take the first pink active tablet on the first day of menses. Take subsequent pink active tablets once daily at the same time each day for a total of 24 days. Take one white inert tablet daily for 4 days and at the same time of day that active tablets were taken. Begin each subsequent 28-day pack on the same day of the week as the first cycle pack (i.e., on the day after taking the last tablet) If not starting on the first day of menses, use a non-hormonal contraceptive (e.g. condoms and/or spermicide) as back-up until one active tablet has been taken daily for 7 days in a row. Switching to NEXTSTELLIS from another contraceptive method Start NEXTSTELLIS on the day: Combined Oral Contraceptive (COC) When the new pack of the previous COC would have started. Transdermal System When the next application would have been scheduled. Vaginal Insert When the next insertion would have been scheduled. Injection When the next injection would have been scheduled. Intrauterine System (IUS) After removal. Implant After removal. Progestin-only pill After the last tablet was taken. Starting NEXTSTELLIS after delivery (>20 weeks gestation) Must not start earlier than 4 weeks after delivery (due to the increased risk of thromboembolism If menstrual cycles have returned, follow instructions for "Starting NEXTSTELLIS in females with no current use of hormonal contraception". If menstrual cycles have not resumed, consider the possibility of ovulation and pregnancy. If not pregnant, use additional nonhormonal contraception for the first 7 days of NEXTSTELLIS use. Starting NEXTSTELLIS after Abortion or Miscarriage ≤14 weeks gestation Within the first 7 days of complete first trimester abortion or miscarriage, use additional nonhormonal contraception for the next 7 days. After the first 7 days, follow instructions for "Starting NEXTSTELLIS in females with no current use of hormonal contraception". > 14 weeks but ≤ 20 weeks gestation After 4 weeks following second trimester abortion or miscarriage. Consider duration of pregnancy and increased risk of thromboembolism If menstrual cycles have returned, follow instructions for "Starting NEXTSTELLIS in females with no current use of hormonal contraception." If menstrual cycles have not resumed, consider the possibility of ovulation and pregnancy. If not pregnant, use additional nonhormonal contraception for the first 7 days of NEXTSTELLIS use

Missed Doses Table 2 Instructions for Missed NEXTSTELLLIS Tablets in a Monthly Dosing Regimen If one pink active tablet is missed Take the missed tablet as soon as possible and take the next tablet at the scheduled time, even if two active tablets are taken in one day. Continue taking one tablet a day until the pack is finished. If two or more pink active tablets are missed in Week 1 or Week 2 Take one missed tablet as soon as possible and take the tablet for the current day (that means taking two tablets in one day) and discard the other missed tablets. Continue taking one tablet a day until the pack is finished. Use additional non-hormonal contraception as back-up until pink tablets have been taken for 7 consecutive days. If two pink active tablets are missed in Week 3 Take one missed tablet as soon as possible and take the tablet for the current day (that means taking two tablets in one day) and discard the other missed tablets. Finish the active tablets and discard the inactive tablets in the pack. Start a new pack of tablets the next day. Use additional non-hormonal contraception as back-up until pink tablets have been taken for 7 consecutive days. If one or more white inert tablets are missed Skip the missed pill days and continue taking one tablet a day until the pack is finished

Administration Recommendations after Vomiting or Acute Diarrhea If vomiting or acute diarrhea occurs within 3 to 4 hours after taking an active tablet, take the new active tablet (scheduled for the next day) as soon as possible. Take the new tablet within 12 hours of the usual time of tablet-taking if possible. If more than two tablets are missed, follow the advice concerning missed tablets, including using backup non-hormonal contraception. For additional recommendations, refer to the table above .

Thromboembolic Disorders and Other Vascular Problems : Stop NEXTSTELLIS if a thrombotic or thromboembolic event occurs. Start no earlier than 4 weeks after delivery. Consider all cardiovascular risk factors before initiating in any female, particularly in the presence of multiple risk factors. Hyperkalemia : Check serum potassium concentration during the first NEXTSTELLIS treatment cycle in females on long-term treatment with medications that may increase serum potassium concentration. Hypertension : Monitor blood pressure periodically and stop use if blood pressure rises significantly. Migraine : Discontinue if new, recurrent, persistent, or severe migraines occur. Hormonally-Sensitive Malignancy: Discontinue NEXTSTELLIS if a hormonally-sensitive malignancy is diagnosed. Liver Disease : Withhold or permanently discontinue for persistent or significant elevation of liver enzymes. Glucose Tolerance and Hypertriglyceridemia : Monitor glucose in females with prediabetes or diabetes. Consider an alternate contraceptive method for females with hypertriglyceridemia. Gallbladder Disease and Cholestasis : Consider discontinuing NEXTSTELLIS in females with symptomatic gallbladder or cholestatic disease. Bleeding Irregularities and Amenorrhea : May cause irregular bleeding or amenorrhea. Evaluate for other causes if symptoms persist. 5.1 Thromboembolic Disorders and Other Vascular Problems Stop NEXTSTELLIS if an arterial or venous thrombotic/thromboembolic event occurs. Stop NEXTSTELLIS if there is unexplained loss of vision, proptosis, diplopia, papilledema, or retinal vascular lesions and evaluate for retinal vein thrombosis immediately. Discontinue NEXTSTELLIS during prolonged immobilization. Start NEXTSTELLIS no earlier than four weeks after delivery in females who are not breast feeding. The risk of postpartum thromboembolism decreases after the third postpartum week, whereas the likelihood of ovulation increases after the third postpartum week. Before starting NEXTSTELLIS, evaluate any past medical history or family history of thrombotic or thromboembolic disorders and consider whether the history suggests an inherited or acquired hypercoagulopathy. NEXTSTELLIS is contraindicated in females with a high risk of arterial or venous thrombotic/thromboembolic diseases . Cardiovascular and Cerebrovascular Events Use of CHCs increases the risk of cardiovascular events and cerebrovascular events, such as myocardial infarction and stroke. The risk is greater among females over age 40, smokers, and females with hypertension, dyslipidemia, diabetes, or obesity. The risk increases with age, particularly in females 35 years of age and older, and with the number of cigarettes smoked. In addition to cigarettes, use of other nicotine-containing products – including cigars, smokeless tobacco, hookah tobacco, e-cigarettes, and nicotine replacement therapy – may also increase the risk of serious cardiovascular events from CHC use. Venous Thromboembolism Use of CHCs also increases the risk of venous thromboembolic events (VTEs), such as deep vein thrombosis and pulmonary embolism. The rate of VTE in females using COCs has been estimated to be 3 to 9 cases per 10,000 woman-years and should be considered in the context of other female of reproductive potential subpopulations who are not taking CHCs . Risk factors for VTEs include smoking, obesity, family history of VTE, and prolonged immobilization in addition to other factors that contraindicate use of CHCs . The presence of multiple risk factors for VTE may increase the risk synergistically. The risk of VTE is highest during the first year of CHC use and when restarting hormonal contraception after a break of four weeks or longer. The risk of VTE returns to baseline approximately 3 months after CHC use is discontinued. Postpartum Venous Thromboembolism The risk of VTE is increased during the first six weeks postpartum compared to the risk in non-pregnant, non-postpartum females. The risk is highest in the first three weeks postpartum , but remains higher than baseline until at least six weeks postpartum. The presence of multiple risk factors for VTE may further increase the risk. Obstetric complications may extend the elevated risk up to 12 weeks postpartum. Figure 1 shows the risk of developing a VTE for females who are not pregnant and do not use COCs, for females who use COCs, for pregnant females, and for females in the postpartum period. To put the risk of developing a VTE into perspective: if 10,000 females who are not pregnant and do not use oral contraceptives are followed for one year, between 1 and 5 of these females will develop a VTE. Figure 1 Likelihood of Developing a VTE Two prospective studies of NEXTSTELLIS have been conducted, one in Europe/Russia (NCT02817828; C301) and one in North America (NCT02817841; C302) (N=3,632), for the prevention of pregnancy in females 16-50 years of age. There was one reported VTE in the Europe/Russia study . Figure 1 5.2 Hyperkalemia NEXTSTELLIS is contraindicated in females with conditions that predispose to hyperkalemia (e.g., renal impairment, hepatic impairment, and adrenal insufficiency). Females receiving daily, long-term treatment for chronic conditions or diseases with medications that may increase serum potassium concentration should have their serum potassium concentration checked during the first treatment cycle. Monitor serum potassium concentration in females at increased risk for hyperkalemia (i.e., those females who take a strong CYP3A4 inhibitor long-term and concomitantly with NEXTSTELLIS). . Monitor females taking NEXTSTELLIS who later develop medical conditions and/or begin medication that put them at an increased risk for hyperkalemia. NEXTSTELLIS contains drospirenone, a progestin, which has anti-mineralocorticoid activity, including the potential for hyperkalemia in high-risk females, comparable to a 25 mg dose of spironolactone. In two Phase 3 trials of NEXTSTELLIS (N = 3,632) for the prevention of pregnancy in females 16-50 years of age, seven subjects were noted to have hyperkalemia and one subject discontinued due to elevated potassium levels. Most females who developed hyperkalemia in the clinical development studies of NEXTSTELLIS had only mild potassium elevations and/or isolated increases that returned to normal while still on study medication

Hypertension NEXTSTELLIS is contraindicated in females with uncontrolled hypertension or hypertension with vascular disease . For all females, including those with well-controlled hypertension, monitor blood pressure periodically and stop NEXTSTELLIS if blood pressure rises significantly. An increase in blood pressure has been reported in females using COCs. This increase is more likely in older females with extended duration of use

Migraine NEXTSTELLIS is contraindicated in females who have migraines with aura . Discontinue NEXTSTELLIS in females using NEXTSTELLIS who develop new migraines that are recurrent, persistent, or severe. Discontinue NEXTSTELLIS if there is an increased frequency or severity of migraines during CHC use (which may be prodromal of a cerebrovascular event). Migraines with aura increase the risk for stroke. This stroke risk is further increased in females who have migraines with aura with use of CHCs

Malignant Neoplasms Breast Cancer NEXTSTELLIS is contraindicated in females who currently have or have had breast cancer because breast cancer may be hormonally sensitive . Epidemiology studies have not found a consistent association between use of combined oral contraceptives (COCs) and breast cancer risk. Studies do not show an association between ever (current or past) use of COCs and risk of breast cancer. However, some studies report a small increase in the risk of breast cancer among current or recent users (<6 months since last use) and current users with longer duration of COC use . Cervical Cancer A causal relationship between the use of CHCs and the development of cervical cancer and intraepithelial neoplasia has not been clearly established. In observational studies, the use of oral hormonal contraceptives in females for five years or more, compared to females who did not use oral hormonal contraceptives, was associated with an increased risk of cervical cancer and intraepithelial neoplasia. In these studies, the use of oral hormonal contraceptives in females for 10 years or more, compared to females who received oral hormonal contraceptives for 5-9 years, was associated with an increased risk of cervical cancer and intraepithelial neoplasia. Limitations in these epidemiologic studies include potential recall bias, differences in sexual behavior, and other factors such as establishing whether there were data on persistent high-risk Human Papilloma Virus (HPV) infection

Liver Disease Elevated Liver Enzymes NEXTSTELLIS is contraindicated in females with acute hepatitis or severe (decompensated) cirrhosis . Withhold or permanently discontinue NEXTSTELLIS for persistent or significant elevation of liver enzymes. NEXTSTELLIS can cause elevated liver enzymes. Liver Tumors NEXTSTELLIS is contraindicated in females with hepatic adenomas and malignant liver tumors . CHCs increase the risk of hepatic tumors, particularly hepatic adenomas. Rupture of hepatic adenomas may cause death from abdominal hemorrhage

Risk of Liver Enzyme Elevations with Concomitant Hepatitis C Treatment CHCs, such as NEXTSTELLIS, are contraindicated for use with Hepatitis C drug combinations containing ombitasvir/paritaprevir/ritonavir (with or without dasabuvir) . Discontinue NEXTSTELLIS prior to starting therapy with the combination drug regimen ombitasvir/paritaprevir/ritonavir (with or without dasabuvir). NEXTSTELLIS can be restarted approximately 2 weeks following completion of treatment with this hepatitis C combination drug regimen. During clinical trials with the above-mentioned Hepatitis C combination drug regimen, ALT elevations greater than 5 times the upper limit of normal (ULN), including some cases greater than 20 times the ULN, were significantly more frequent in females using ethinyl estradiol (EE)-containing drugs, such as CHCs. Females using medications containing estrogens other than EE had a rate of ALT elevation similar to those not receiving any estrogens. NEXTSTELLIS contains E4 rather than EE, but as no data are available for co-administration with this Hepatitis C combination drug regimen, caution is warranted

Glucose Tolerance and Hypertriglyceridemia Glucose Tolerance Carefully monitor females with prediabetes and diabetes who are using NEXSTELLIS. NEXTSTELLIS may decrease glucose tolerance . Hypertriglyceridemia Consider alternative contraception for females with hypertriglyceridemia. Females with hypertriglyceridemia, or a family history thereof, may have an increase in serum triglyceride concentrations when using NEXSTELLIS, which may increase the risk of pancreatitis

Gallbladder Disease and Cholestasis Consider discontinuing NEXTSTELLIS in females with symptomatic gallbladder disease or cholestatic disease. Studies suggest an increased risk of developing gallbladder disease among CHC users. Use of CHCs may also worsen existing gallbladder disease. A past history of CHC-related cholestasis predicts an increased risk with subsequent CHC use. Females with a history of pregnancy-related cholestasis may be at an increased risk for CHC-related cholestasis

Effect on Binding Globulins Increase the dosage of thyroid hormone replacement therapy as needed in females taking NEXTSTELLIS . The estrogen component of NEXTSTELLIS may increase the serum concentrations of thyroxine-binding globulin, sex hormone-binding globulin, and cortisol-binding globulin

Bleeding Irregularities and Amenorrhea Unscheduled Bleeding and Spotting Females using NEXTSTELLIS may experience unscheduled (breakthrough or intracyclic) bleeding and spotting, especially during the first 4 months of use. Bleeding irregularities may resolve over time or by changing to a different contraceptive product. If bleeding persists or occurs after previously regular cycles, evaluate for causes such as pregnancy or malignancy. Unscheduled bleeding was defined as bleeding or spotting that occurred on Day 4 through Day 24 of a 28-day cycle. Based on subject diaries from C302 (US/CA), the proportion of subjects reporting unscheduled bleeding or spotting per 28-day cycle decreased over time: 30.3% at Cycle 1 versus 17.4% at Cycle 12. The mean number of unscheduled bleeding/spotting days per cycle also gradually decreased over time, with a mean of 0.4 (± 1.42) bleeding days at Cycle 1, versus a mean of 0.2 (± 0.98) bleeding days at Cycle 12 . Absence of Scheduled Bleeding Females who use NEXTSTELLIS may experience absence of scheduled (withdrawal) bleeding, even if they are not pregnant . The proportion of subjects reporting absence of scheduled bleeding remained constant overall, with on average 15.5% of subjects reporting absence of scheduled bleeding from Cycles 1 through 12. If scheduled bleeding does not occur, consider the possibility of pregnancy. If the patient has not adhered to the prescribed dosing schedule (missed one or two active tablets or started taking them on a day later than prescribed), consider the possibility of pregnancy at the time of the first missed period and perform appropriate diagnostic measures. After discontinuation of NEXTSTELLIS, amenorrhea or oligomenorrhea may occur, especially if these conditions were pre-existent

Depression Monitor females with a history of depression and discontinue NEXTSTELLIS if depression recurs to a serious degree. Data on the association of COCs with onset of depression or exacerbation of existing depression are limited

Hereditary Angioedema Avoid NEXTSTELLIS in females with hereditary angioedema. Exogenous estrogens may induce or exacerbate symptoms of hereditary angioedema

Chloasma Avoid NEXTSTELLIS in females with a history of chloasma gravidarum or increased sensitivity to sun and/or ultraviolet radiation exposure. Chloasma may occur with NEXTSTELLIS use, especially in females with a history of chloasma gravidarum.

CYP3A Inducers: May lead to contraceptive failure and/or increase breakthrough bleeding. Avoid concomitant use. If concomitant use is unavoidable, use an alternative or back-up contraceptive method during co-administration and up to 28 days after discontinuation of the CYP3A inducer. See Full Prescribing Information for additional clinically significant drug interactions

Effects of Other Drugs on Hormonal Contraceptives Clinically significant drug interactions with other drugs that affect NEXTSTELLIS are presented in Table 5. Table 5. Clinically Significant Drug Interactions With Other Drugs that Affect NEXTSTELLIS CYP3A Inducers Clinical Effect DRSP is a CYP3A4 substrate. Concomitant use with strong CYP3A inducers or certain moderate or weak CYP3A inducers may decrease DRSP exposure , which may lead to contraceptive failure. Prevention or Management Strong CYP3A Inducers Avoid concomitant use. If concomitant use is unavoidable, use an alternative contraceptive method (e.g., intrauterine system) or backup non-hormonal contraceptive method during coadministration and up to 28 days after discontinuation of the strong CYP3A inducer. Moderate and Weak CYP3A Inducers Use an alternative or backup contraceptive method during coadministration and up to 28 days after discontinuation of the CYP3A inducer, unless the Prescribing Information of the specific moderate or weak CYP3A inducer indicates there is no clinically significant interaction with NEXTSTELLIS. Strong CYP3A Inhibitors Clinical Effect DRSP is a CYP3A4 substrate. Concomitant use with a strong CYP3A inhibitor may increase DRSP exposure , which may increase the risk of adverse reactions of NEXTSTELLIS, including hyperkalemia . Prevention or Management Consider monitoring serum potassium concentration in patients who take a strong CYP3A4 inhibitor long-term and concomitantly with NEXTSTELLIS. Drugs that May Reduce the Absorption of NEXTSTELLIS Clinical Effect Concomitant use with drugs such as bile acid sequestrants may decrease the E4 and DRSP exposure, which may lead to contraceptive failure and/or an increase in breakthrough bleeding. Prevention or Management Separate time of administration of NEXTSTELLIS and the concomitant drug. Refer to the concomitant drug's Prescribing Information for additional information

Effects of NEXTSTELLIS on Other Drugs Table 6 includes clinically significant drug interactions with NEXTSTELLIS that affect other drugs. Table 6. Clinically Significant Drug Interactions of NEXTSTELLIS on Other Drugs Anti-Diabetic Drugs Clinical Effect Concomitant use of NEXTSTELLIS may reduce the blood glucose lowering effect of anti-diabetic drugs . Prevention or Management Monitor serum potassium concentration in females at increased risk for hyperkalemia. Lamotrigine Clinical Effect Concomitant use of NEXTSTELLIS may decrease lamotrigine exposure , which may reduce efficacy of lamotrigine. Prevention or Management Adjust lamotrigine dosage as recommended in its Prescribing Information based on NEXTSTELLIS initiation or discontinuation. Systemic Corticosteroids Clinical Effect Concomitant use of NEXTSTELLIS may increase the exposure of certain systemic corticosteroids, which may increase the risk of corticosteroid-related adverse reactions [ see Clinical Pharmacology . Prevention or Management Follow the recommendation for the corticosteroid in accordance with its Prescribing Information. Consider more frequent monitoring for corticosteroid adverse reactions when used concomitantly with NEXTSTELLIS. Thyroid Hormone Replacement Therapy Clinical Effect Concomitant use of NEXTSTELLIS may increase thyroid-binding globulin concentration . Prevention or Management Monitor thyroid-stimulating hormone (TSH) level and follow the recommendation for thyroid hormone replacement in accordance with its Prescribing Information.
