xocova

Verify pregnancy status of females of reproductive potential prior to initiating XOCOVA. ( 2.1 ) Begin XOCOVA as soon as possible and within 72 hours following contact with an individual who has COVID-19. ( 2.2 ) Dosage: 375 mg (three 125-mg tablets taken at the same time) orally on Day 1 and 125 mg (one 125-mg tablet) orally on Days 2 to 5 taken with or without food. ( 2.2 ) 2.1 Pregnancy Evaluation Prior to Initiating XOCOVA Verify pregnancy status of females of reproductive potential prior to initiating XOCOVA [see Warnings and Precautions (5.1) and Use in Specific Populations (8.1 , 8.3) ] . 2.2 Recommended Dosage The recommended dosage of XOCOVA in adults and adolescents 12 years of age and older is 375 mg (three 125-mg tablets taken together) orally on Day 1 and 125 mg (one 125-mg tablet) orally on Days 2 to 5 with or without food [see Clinical Pharmacology (12.3) ] . Begin XOCOVA as soon as possible and within 72 hours following contact with an individual who has COVID-19. The tablets should be taken at approximately the same time each day. If a dose of XOCOVA is missed, take the missed dose as soon as possible on the same day, and then take the next dose as scheduled the following day.

The following clinically significant adverse reactions are described elsewhere in the labeling: Hypersensitivity reactions including anaphylaxis [see Warnings and Precautions (5.3) ] The most common adverse events (regardless of causality) occurring in ≥1% of the XOCOVA group and at a greater frequency compared to placebo were headache, diarrhea, and cough. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Shionogi Inc. at 1-800-849-9707 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 practice. The overall safety profile of XOCOVA is based on data from 2,831 adults and adolescents exposed to the recommended dosage and duration of XOCOVA in controlled clinical trials. Trial SCORPIO-PEP was a randomized, double-blind, placebo-controlled trial in which 1,190 subjects received oral XOCOVA (375 mg [Day 1]/125 mg [Days 2-5]) and 1,187 subjects received oral placebo (Days 1-5). The most common adverse events (regardless of causality) occurring in ≥1% of the XOCOVA group and at a greater frequency compared to placebo were headache (2.9% and 2.6%, respectively), diarrhea (1.7% and 1.3%,…

XOCOVA is contraindicated in patients with a history of clinically significant hypersensitivity reactions to ensitrelvir or any other components of the product. XOCOVA is contraindicated in patients taking drugs that are: Primarily metabolized by CYP3A for which elevated concentrations may be associated with serious and/or life-threatening reactions [see Drug Interactions (7.3) ] and Strong CYP3A inducers because they may significantly reduce ensitrelvir plasma concentrations, leading to the potential loss of virologic response [see Drug Interactions (7.3) ] . History of clinically significant hypersensitivity reactions to ensitrelvir or any other components of the product. ( 4 ) Co-administration with drugs primarily metabolized by CYP3A for which elevated concentrations may be associated with serious and/or life-threatening reactions. ( 4 , 7.3 ) Co-administration with strong CYP3A inducers considered to significantly reduce ensitrelvir plasma concentrations and may be associated with the potential for loss of virologic response. ( 4 , 7.3 )

Treatment of overdose with XOCOVA should consist of general supportive measures, including monitoring of vital signs and observation of the clinical status of the patient. There is no specific antidote for overdose with XOCOVA.

Co-administration of XOCOVA can alter the plasma concentrations of other drugs, and other drugs may alter the plasma concentrations of XOCOVA. Consider the potential for drug interactions prior to and during XOCOVA use and review concomitant medications during XOCOVA use. ( 4 , 5.2 , 7 , 12.3 ) 7.1 Potential for XOCOVA to Affect Other Drugs Ensitrelvir is a strong inhibitor of CYP3A and an inhibitor of P-gp and BCRP. Co-administration of XOCOVA with drugs that are primarily metabolized by CYP3A or are transported by P-gp or BCRP may result in increased plasma concentrations of such drugs and increase the risk of adverse events [see Contraindications (4) , Warnings and Precautions (5.2) , Drug Interactions (7.3) , and Clinical Pharmacology (12.3) ] . For drugs that are CYP3A substrates and contraindicated with XOCOVA, initiation of XOCOVA should be considered only after careful evaluation of relevant clinical and pharmacokinetic factors related to the concomitant medication. In addition, re-initiation of contraindicated CYP3A substrates should be considered based on an assessment of the duration of CYP3A inhibition and patient‑specific considerations. Refer to individual drug prescribing information for additional information. 7.2 Potential for Other Drugs to Affect XOCOVA Ensitrelvir is a CYP3A substrate; therefore, drugs that induce CYP3A may decrease ensitrelvir plasma concentrations and reduce XOCOVA therapeutic effect [see Drug Interactions (7.3) and Clinical Pharmacology (12.3) ] . Therefore, use of XOCOVA with strong CYP3A4 inducers is contraindicated [see Contraindications (4) ] . No dose adjustment is recommended when XOCOVA is used concomitantly with moderate or weak CYP3A inducers [see Warnings and Precautions (5.2) ] . Refer to individual drug prescribing information for additional information. 7.3 Established and Other Potentially Significant Drug Interactions Table 1 provides examples of drugs that are contraindicated with XOCOVA [see Contraindications (4) and Warnings and Precautions (5.2) ] . Table 1 is provided as a guide and is not a comprehensive list of all possible drugs that may interact with XOCOVA. The healthcare provider should consult other appropriate resources, such as the prescribing information for the interacting drug, for comprehensive information on dosing and monitoring with concomitant use of a strong CYP3A inhibitor, like XOCOVA [see Drug Interactions (7.1) ].
