Important safety information

CYP3A4 Interactions : Aprepitant is a substrate, weak-to-moderate (dose-dependent) inhibitor and an inducer of CYP3A4; see Full Prescribing Information for recommendations regarding contraindications, risk of adverse reactions, and dosage adjustment of CINVANTI and concomitant drugs. ( 4 , 5.1 , 7.1 , 7.2 ) Hypersensitivity Reactions (including anaphylaxis ): May occur during or soon after administration. If symptoms occur, discontinue CINVANTI and do not reinitiate it. ( 4 , 5.2 ) Warfarin (a CYP2C9 substrate) : Risk of decreased INR of prothrombin time; monitor INR in 2–week period, particularly at 7 to 10 days, following initiation of CINVANTI. ( 5.3 , 7.1 ) Hormonal Contraceptives : Efficacy of contraceptives may be reduced during and for 28 days following administration of aprepitant. Use effective alternative or back-up methods of non-hormonal contraception. ( 5.4 , 7.1 , 8.3 ) 5.1 Clinically Significant CYP3A4 Drug Interactions Aprepitant is a substrate, weak-to-moderate (dose-dependent) inhibitor, and an inducer of CYP3A4. Use of CINVANTI with other drugs that are CYP3A4 substrates may result in increased plasma concentration of the concomitant drug. Use of pimozide with CINVANTI is contraindicated due to the risk of significantly increased plasma concentrations of pimozide, potentially resulting in prolongation of the QT interval, a known adverse reaction of pimozide [see Contraindications (4) ] . Use of CINVANTI with strong or moderate CYP3A4 inhibitors (e.g., ketoconazole, diltiazem) may increase plasma concentrations of aprepitant and result in an increased risk of adverse reactions related to CINVANTI. Use of CINVANTI with strong CYP3A4 inducers (e.g., rifampin) may result in a reduction in aprepitant plasma concentrations and decreased efficacy of CINVANTI. See Table 8 and Table 9 for a listing of potentially significant drug interactions [see Drug Interactions (7.1 , 7.2) ]. 5.2 Hypersensitivity Reactions Serious hypersensitivity reactions, including anaphylaxis during or soon after administration of CINVANTI have occurred. Symptoms including dyspnea, eye swelling, flushing, pruritus and wheezing have been reported [see Adverse Reactions (6.2) ] . Monitor patients during and after administration. If hypersensitivity reactions occur, discontinue CINVANTI and administer appropriate medical therapy. Do not reinitiate CINVANTI in patients who experience these symptoms with previous use. 5.3 Decrease in INR with Concomitant Warfarin Coadministration of CINVANTI with warfarin, a CYP2C9 substrate, may result in a clinically significant decrease in the International Normalized Ratio (INR) of prothrombin time [see Clinical Pharmacology (12.3) ] . Monitor the INR in patients on chronic warfarin therapy in the 2-week period, particularly at 7 to 10 days, following initiation of CINVANTI with each chemotherapy cycle [see Drug Interactions (7.1) ] . 5.4 Risk of Reduced Efficacy of Hormonal Contraceptives Upon coadministration with CINVANTI, the efficacy of hormonal contraceptives may be reduced during administration of and for 28 days following the last dose of CINVANTI [see Clinical Pharmacology (12.3) ] . Advise patients to use effective alternative or back-up methods of non-hormonal contraception during treatment with CINVANTI and for 1 month following administration of CINVANTI or oral aprepitant, whichever is administered last [see Drug Interactions (7.1) , Use in Specific Populations (8.3) ] .

Who should not take Cinvanti

CINVANTI is contraindicated in patients: who are hypersensitive to any component of the product [see Description (11) ] . Hypersensitivity reactions including anaphylaxis have been reported [see Warnings and Precautions (5.2) , Adverse Reactions (6.2) ] . taking pimozide. Inhibition of CYP3A4 by aprepitant could result in elevated plasma concentrations of pimozide, which is a CYP3A4 substrate, potentially causing serious or life-threatening reactions, such as QT prolongation, a known adverse reaction of pimozide [see Warnings and Precautions (5.1) ] . Known hypersensitivity to any component of this drug. ( 4 , 5.2 ) Concurrent use with pimozide. ( 4 )

Overdose — what happens if you take too much

There is no specific information on the treatment of overdosage with aprepitant. In the event of overdose, CINVANTI should be discontinued and general supportive treatment and monitoring should be provided. Because of the antiemetic activity of CINVANTI, drug-induced emesis may not be effective in cases of CINVANTI overdosage. Aprepitant is not removed by hemodialysis.
