How to use
The recommended dosage is 120 mg (two 60 mg capsules) orally once daily at bedtime with or without food. ( 2.2 ) Swallow capsules whole. Do not cut, crush, or chew capsules. ( 2.2 ) See full prescribing information for LYNKUET dosage modification due to drug interactions. ( 2.3 ) 2.1 Recommended Evaluation and Testing Before Initiation of LYNKUET Exclude pregnancy in females of reproductive potential [see Contraindications (4) ], Warnings and Precautions (5.3) , and Use in Specific Populations (8.3) ]. Perform baseline hepatic laboratory tests to evaluate for hepatic function and injury [including serum alanine aminotransferase (ALT), serum aspartate aminotransferase (AST), serum alkaline phosphatase (ALP), and serum bilirubin (total and direct)] before initiating treatment with LYNKUET. Do not start LYNKUET if ALT or AST is ≥ 2 times upper limit of normal (ULN) or if the total bilirubin is ≥ 2 times ULN [ see Warnings and Precautions (5.2) and Use in Specific Populations (8.7) ]. 2.2 Recommended Dosage The recommended dosage of LYNKUET is 120 mg (two 60 mg capsules) orally once daily at bedtime at about the same time each day.

Take LYNKUET with water and swallow capsules whole. Do not cut,…
Side effects
The following clinically significant adverse reactions are described elsewhere in the labeling: Central Nervous System (CNS) Depressant Effect and Daytime Impairment [see Warnings and Precautions (5.1) ] Hepatic Transaminase Elevations [see Warnings and Precautions (5.2) ] The most frequently reported (≥5%) adverse reactions were headache, fatigue, dizziness and somnolence. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Bayer HealthCare Pharmaceuticals Inc. at 1-888-842-2937 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 clinical practice. The safety of LYNKUET was evaluated in three randomized, double-blind, placebo-controlled, multicenter clinical trials (OASIS 1, OASIS 2, OASIS 3 ) in 1420 women . In OASIS 1 and OASIS 2 combined, 793 women received LYNKUET or placebo for 12 weeks. After the first 12 weeks, 341 women randomized to LYNKUET continued to receive LYNKUET for another 14 weeks, with a total treatment duration of up to 26 weeks. In OASIS 1 and OASIS 2 combined, 349 women received placebo for the first 12 weeks and 348 women switched to LYNKUET for the next 14 weeks. In OASIS…
Warnings
Important safety information
CNS Depressant Effect and Daytime Impairment: Advise patients about the potential for somnolence and other nervous system effects. Advise patients who experience these effects to refrain from driving or engaging in hazardous occupations or activities until the effects have resolved ( 5.1 ) Hepatic Transaminase Elevations: Perform bloodwork prior to initiation of LYNKUET to evaluate for hepatic function and injury. Do not start therapy if serum transaminase concentration is equal to or exceeds two times the upper limit of normal (ULN). Perform follow-up evaluations of hepatic transaminase concentration 3 months after initiation. Do not start therapy if serum transaminase concentration is equal to or exceeds two times the ULN or if the total bilirubin is equal to or exceeds two times the ULN. Advise patients to discontinue LYNKUET immediately in case of signs or symptoms suggesting liver injury. ( 5.2 ) Risk of pregnancy loss: May cause pregnancy loss or stillbirth when administered during pregnancy. Exclude pregnancy in females of reproductive potential prior to initiating LYNKUET. Discontinue if pregnancy is confirmed ( 5.3 ) Risk of seizures in patients with a history of seizures ( 5.4 ) 5.1 Central Nervous System (CNS) Depressant Effect and Daytime Impairment In the three OASIS trials, nervous system effects (including somnolence, fatigue, vertigo, dizziness and presyncope) occurred in 11.9% of patients on LYNKUET compared to 3.5% on placebo. [see also Adverse Reactions (6.1) ]. Advise patients about the potential for somnolence and other nervous system effects. Advise patients who experience these effects to refrain from driving or engaging in hazardous occupations or activities until the effects have resolved [see Clinical Studies (14.3) ]. 5.2 Hepatic Transaminase Elevations Elevations in serum transaminase (ALT and/or AST) concentrations equal to or greater than three times the ULN occurred in 0.6% of patients receiving LYNKUET and 0.4% of patients receiving placebo up to 12 weeks in three clinical trials. Perform baseline bloodwork (including ALT, AST, alkaline phosphatase, and total and direct bilirubin) prior to initiation of LYNKUET to evaluate for hepatic function and injury. Do not start therapy if serum transaminase concentration is equal to or exceeds two times the ULN or if the total bilirubin is equal to or exceeds two times the ULN. Perform follow-up evaluations of hepatic transaminase concentration 3 months after initiation of therapy. Advise patients to discontinue LYNKUET immediately and seek medical attention including hepatic laboratory tests if they experience signs or symptoms that may suggest liver injury (new onset fatigue, decreased appetite, nausea, vomiting, pruritus, jaundice, pale feces, dark urine, or abdominal pain). Discontinue LYNKUET if transaminase elevations exceed five times the ULN or if transaminase elevations exceed three times the ULN and total bilirubin exceeds two times the ULN. Exclude alternative causes of hepatic laboratory test elevations. 5.3 Risk of Pregnancy Loss LYNKUET is contraindicated for use in pregnancy [see Contraindications (4) ]. Findings from animal studies suggest that LYNKUET can cause pregnancy loss or stillbirth. Exclude pregnancy in females of reproductive potential prior to initiating LYNKUET. Advise females of reproductive potential to use effective contraception during treatment with LYNKUET and for 2 weeks after stopping LYNKUET [see Use in Specific Populations (8.1 , 8.3) ] . 5.4 Risk of Seizures in Patients with History of Seizures Seizure was reported in one patient with a history of seizures in the clinical trials of LYNKUET. In addition, convulsions were observed in studies conducted in male and female rats [see Nonclinical Toxicology (13.2) ]. Use LYNKUET with caution in patients with a history of seizures or with conditions that potentially lower the seizure threshold.

Interactions
Strong CYP3A4 Inhibitors and grapefruit (juice): Avoid concomitant use with LYNKUET. ( 7.1 ) Moderate CYP3A4 Inhibitors: Reduce LYNKUET dosage to 60 mg once daily. ( 2.2 , 7.1 ) Strong and Moderate CYP3A4 Inducers: Avoid concomitant use with LYNKUET. ( 7.1 ) 7.1 Effects of Other Drugs on LYNKUET Elinzanetant is primarily metabolized via CYP3A4 enzyme. Table 3 describes drug interactions where concomitant use of another drug affects LYNKUET. Table 3: Drug Interactions: Concomitant Use of Other Drugs Affect the Use of LYNKUET Strong and Moderate CYP3A4 Inhibitors See www.fda.gov/CYPandTransporterInteractingDrugs for examples of strong and moderate CYP3A4 inhibitors, and CYP3A4 inducers. Prevention or Management Strong CYP3A4 Inhibitors and grapefruit (juice): Avoid concomitant use. Moderate CYP3A4 Inhibitors: Reduce the LYNKUET dosage [see Dosage and Administration (2.2) ]. Clinical Effect(s) Strong and moderate CYP3A4 inhibitors increase elinzanetant exposure, which may increase the risk of LYNKUET-associated adverse reactions [see Clinical Pharmacology (12.3) ]. Strong and Moderate CYP3A4 Inducers Prevention or Management Strong and moderate CYP3A4 inducers: Avoid concomitant use. Clinical Effect(s) Strong and moderate CYP3A4 inducers decrease elinzanetant exposure, which may reduce the effectiveness of LYNKUET. 7.2 Effects of LYNKUET on Other Drugs CYP3A4 Substrates Avoid concomitant use unless otherwise recommended in the Prescribing Information for CYP3A4 substrates where minimal concentration changes may lead to serious adverse reactions. See www.fda.gov/CYPandTransporterInteractingDrugs for examples of CYP3A4 substrates. Elinzanetant is a weak inhibitor of CYP3A4. Concomitant use of LYNKUET increases exposure of CYP3A4 substrates [see Clinical Pharmacology (12.3) ] , which may increase the risk of adverse reactions related to these substrates.
