Cariprazine

12.1 Mechanism of Action The mechanism of action of cariprazine is unknown. However, the efficacy of cariprazine could be mediated through a combination of partial agonist activity at central dopamine D 2 and serotonin 5-HT 1A receptors and antagonist activity at serotonin 5-HT 2A receptors. Cariprazine forms two major metabolites, desmethylcariprazine (DCAR) and didesmethylcariprazine (DDCAR), that have in vitro receptor binding profiles similar to the parent drug.

Because of the long half-life of cariprazine and its active metabolites, changes in dose will not be fully reflected in plasma for several weeks. Prescribers should monitor patients for adverse reactions and treatment response for several weeks after starting VRAYLAR and after each dosage change [see Warnings and Precautions ( 5.6 ) , Clinical Pharmacology ( 12.3 )] . 2.2 Recommended Dosage in Schizophrenia Adult Patients The starting dosage of VRAYLAR is 1.5 mg orally once daily. The recommended dosage range is 1.5 mg to 6 mg orally once daily. The dosage can be increased to 3 mg on Day 2. Depending upon clinical response and tolerability, further dose adjustments can be made in 1.5 mg or 3 mg increments. The maximum recommended dosage is 6 mg orally once daily. In short-term controlled trials, dosages above 6 mg daily do not confer increased effectiveness sufficient to outweigh dose-related adverse reactions [see Adverse Reactions ( 6.1 ), Clinical Studies ( 14.1 )] . Pediatric Patients (13 to 17 years of age) The starting dosage of VRAYLAR is 0.5 mg orally once daily. The recommended dosage range is 1.5 mg to 4.5 mg orally once daily. Increase the dosage to 1.5 mg orally once daily on Day 3. Depending upon clinical response and tolerability, the dosage may be increased to 3 mg orally once daily starting on Day 5, and to 4.5 mg orally once daily starting on Day 8. The maximum recommended dosage is 4.5 mg orally once daily. 2.3 Recommended Dosage in Manic or M ixed E pisodes Associated with Bipolar I Disorder Adult Patients The starting dosage of VRAYLAR is 1.5 mg orally once daily. Increase the dosage to 3 mg orally once daily on Day 2. The recommended dosage range is 3 mg to 6 mg orally once daily. Depending upon clinical response and tolerability, further dose adjustments can be made in 1.5 mg or 3 mg increments. The maximum recommended dosage is 6 mg orally once daily. In short-term controlled trials, dosages above 6 mg daily do not confer increased effectiveness sufficient to outweigh dose-related adverse reactions [ see Adverse Reactions ( 6.1 ), Clinical Studies ( 14.2 ) ] . Pediatric Patients (10 to 17 years of age)​ The starting dosage of VRAYLAR is 0.5 mg orally once daily. The recommended dosage is 3 mg or 4.5 mg orally once daily. Increase the dosage to 1.5 mg orally once daily on Day 3 and to 3 mg orally once daily on Day 5. Depending upon clinical response and tolerability, the dosage may be increased to 4.5 mg orally once daily starting on Day 8. The maximum recommended dosage is 4.5 mg orally once daily. 2.4 Recommended Dosage in Depressive Episodes Associated with Bipolar I Disorder (Bipolar Depression) in Adult Patients The starting dosage of VRAYLAR is 1.5 mg orally once daily.

The information below is derived from an integrated clinical study database for VRAYLAR consisting of 6,722 adult patients exposed to one or more doses of VRAYLAR for the treatment of schizophrenia, manic or mixed episodes associated with bipolar I disorder, bipolar depression, and adjunctive treatment of major depressive disorder in placebo-controlled studies. This experience corresponds with a total experience of 1,182.8 patient-years. A total of 4,329 VRAYLAR-treated patients had at least 6 weeks and 296 VRAYLAR-treated patients had at least 48 weeks of exposure. Adult Patients with Schizophrenia The following findings are based on four placebo-controlled, 6-week schizophrenia trials with VRAYLAR doses ranging from 1.5 to 12 mg once daily. The maximum recommended dosage is 6 mg daily. Adverse Reactions Associated with Discontinuation of Treatment : There was no single adverse reaction leading to discontinuation that occurred at a rate of ≥ 2% in VRAYLAR-treated patients and at least twice the rate of placebo. Common Adverse Reactions (≥ 5% and at least twice the rate of placebo) : extrapyramidal symptoms and akathisia. Adverse Reactions with an incidence of ≥ 2% and greater than placebo, at any dose are shown in Table 8. Table 8.

7 DRUG INTERACTIONS 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 )
