Cariprazine

Table 15 displays clinically significant drug interactions with VRAYLAR. Table 15. Clinically Significant Drug Interactions with VRAYLAR Strong or Moderate CYP3A4 Inhibitors Clinical Impact: Concomitant use of VRAYLAR with a strong or moderate CYP3A4 inhibitor increases the exposures of cariprazine and its major active metabolite, didesmethylcariprazine (DDCAR), compared to use of VRAYLAR alone [see Clinical Pharmacology ( 12.3 ) ]. Intervention: If VRAYLAR is used with a strong or moderate CYP3A4 inhibitor, reduce VRAYLAR dosage [see D osage and A dministration ( 2.6 ) ] .

CYP3A4 Inducers Clinical Impact: CYP3A4 is responsible for the formation and elimination of the active metabolites of cariprazine. The effect of CYP3A4 inducers on the exposure of VRAYLAR has not been evaluated, and the net effect is unclear [see Clinical Pharmacology ( 12.3 ) ]. Intervention: Concomitant use of VRAYLAR with a CYP3A4 inducer is not recommended [see Dosage and Administration ( 2.1 , 2.6 ) ] . Strong and Moderate CYP3A4 inhibitors: Reduce VRAYLAR dosage ( 2.6 , 7 ) CYP3A4 inducers: Concomitant use is not recommended ( 2.6 , 7 )

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to VRAYLAR during pregnancy. For more information, contact the National Pregnancy Registry for Atypical Antipsychotics at 1-866-961-2388 or visit http://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/. Risk Summary Neonates exposed to antipsychotic drugs during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery (see Clinical Considerations). There are no available data on VRAYLAR use in pregnant women to inform any drug-associated risks for birth defects or miscarriage.

The major active metabolite of cariprazine, DDCAR, has been detected in adult patients up to 12 weeks after discontinuation of VRAYLAR [see Clinical Pharmacology ( 12.3 )]. Based on animal data, VRAYLAR may cause fetal harm. Administration of cariprazine to rats during the period of organogenesis caused malformations, lower pup survival, and developmental delays at drug exposures less than the human exposure at the maximum recommended human dose (MRHD) of 6 mg/day. However, cariprazine was not teratogenic in rabbits at doses up to 4.6 times the MRHD of 6 mg/day [see Data] . The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown.

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Advise pregnant women of the potential risk to a fetus. Clinical Considerations Fetal/Neonatal Adverse Reactions Extrapyramidal and/or withdrawal symptoms, including agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and feeding disorder have been reported in neonates whose mothers were exposed to antipsychotic drugs during the third trimester of pregnancy. These symptoms have varied in severity.

Some neonates recovered within hours or days without specific treatment; others required prolonged hospitalization. Monitor neonates for extrapyramidal and/or withdrawal symptoms and manage symptoms appropriately. Data Animal Data Administration of cariprazine to pregnant rats during the period of organogenesis at oral doses of 0.5, 2.5, and 7.5 mg/kg/day, which are 0.2 to 3.5 times the maximum recommended human dose (MRHD) of 6 mg/day based on AUC of total cariprazine (i.e. sum of cariprazine, DCAR, and DDCAR), caused fetal developmental toxicity at all doses, which included reduced body weight, decreased male…
