⚠ Boxed Warning (Black Box)
WARNING: DEPRESSION AND SUICIDAL IDEATION AND BEHAVIOR IN PATIENTS WITH HUNTINGTON’S DISEASE VMAT2 inhibitors, including INGREZZA and INGREZZA SPRINKLE, can increase the risk of depression and suicidal thoughts and behavior in patients with Huntington’s disease. Anyone considering the use of INGREZZA or INGREZZA SPRINKLE must balance the risks of depression and suicidal ideation and behavior with the clinical need for treatment of chorea. Closely monitor patients for the emergence or worsening of depression, suicidal ideation, or unusual changes in behavior. Inform patients, their caregivers, and families of the risk of depression and suicidal ideation and behavior and instruct them to report behaviors of concern promptly to the treating physician. Particular caution should be exercised in treating patients with a history of depression or prior suicide attempts or ideation, which are increased in frequency in patients with Huntington’s disease [see Warnings and Precautions ( 5.1 )].

The safety of INGREZZA SPRINKLE has been established from adequate and well-controlled studies of INGREZZA [see Clinical Studies ( 14 )] . Below is a display of the adverse reactions of INGREZZA in these adequate and well-controlled studies. Tardive Dyskinesia Variable and Fixed Dose Placebo-Controlled Trial Experience The safety of INGREZZA was evaluated in 3 placebo-controlled studies, each 6 weeks in duration (fixed dose, dose escalation, dose reduction), including 445 patients. Patients were 26 to 84 years of age with moderate to severe tardive dyskinesia and had concurrent diagnoses of mood disorder (27%) or schizophrenia/ schizoaffective disorder (72%). The mean age was 56 years. Patients were 57% Caucasian, 39% African-American, and 4% other. With respect to ethnicity, 28% were Hispanic or Latino. All subjects continued previous stable regimens of antipsychotics; 85% and 27% of subjects, respectively, were taking atypical and typical antipsychotic medications at study entry. Adverse Reactions Leading to Discontinuation of Treatment A total of 3% of INGREZZA-treated patients and 2% of placebo-treated patients discontinued because of adverse reactions. Common Adverse Reactions Adverse reactions that occurred in the 3 placebo-controlled studies at an incidence of ≥2% and greater than placebo are presented in Table 1 . Table 1: Adverse Reactions in 3 Placebo-Controlled Studies of 6-week Treatment Duration Reported at ≥2% and >Placebo – Tardive Dyskinesia Adverse Reaction 1 INGREZZA (n=262) % Placebo (n=183) % General Disorders Somnolence (somnolence, fatigue, sedation) 10.9 4.2 Nervous System Disorders Anticholinergic effects 5.4 4.9 (dry mouth, constipation, disturbance in attention, vision blurred, urinary retention) Balance disorders/fall (fall, gait disturbance, dizziness, balance disorder) 4.1 2.2 Headache 3.4 2.7 Akathisia (akathisia, restlessness) 2.7 0.5 Gastrointestinal Disorders Vomiting 2.6 0.6 Nausea 2.3 2.1 Musculoskeletal Disorders Arthralgia 2.3 0.5 1 Within each adverse reaction category, the observed adverse reactions are listed in order of decreasing frequency.

Drug Interactions
7 DRUG INTERACTIONS Dose adjustments due to drug interactions ( 2.4 , 7.1 ): Factors Dose Adjustments for INGREZZA and INGREZZA SPRINKLE Use of MAOIs with INGREZZA or INGREZZA SPRINKLE Avoid concomitant use with MAOIs. Use of strong CYP3A4 inducers with INGREZZA or INGREZZA SPRINKLE Concomitant use is not recommended. Use of strong CYP3A4 inhibitors with INGREZZA or INGREZZA SPRINKLE Recommended dosage is 40 mg once daily. Use of strong CYP2D6 inhibitors with INGREZZA or INGREZZA SPRINKLE Recommended dosage is 40 mg once daily. 7.1 Drugs Having Clinically Important Interactions with INGREZZA and INGREZZA SPRINKLE Table 3: Clinically Significant Drug Interactions with INGREZZA and INGREZZA SPRINKLE Monoamine Oxidase Inhibitors (MAOIs) Clinical Implication: Concomitant use of INGREZZA or INGREZZA SPRINKLE with MAOIs may increase the concentration of monoamine neurotransmitters in synapses, potentially leading to increased risk of adverse reactions such as serotonin syndrome, or attenuated treatment effect of INGREZZA or INGREZZA SPRINKLE. Prevention or Management: Avoid concomitant use of INGREZZA or INGREZZA SPRINKLE with MAOIs, or within 14 days of discontinuing therapy with an MAOI. Strong CYP3A4 Inhibitors Clinical Implication: Concomitant use of INGREZZA or INGREZZA SPRINKLE with strong CYP3A4 inhibitors increased the exposure (C max and AUC) to valbenazine and its active metabolite compared with the use of INGREZZA or INGREZZA SPRINKLE alone [see Clinical Pharmacology ( 12.3 )]. Increased exposure of valbenazine and its active metabolite may increase the risk of exposure-related adverse reactions [see Warnings and Precautions ( 5.4 )]. Prevention or Management: Reduce INGREZZA or INGREZZA SPRINKLE dose when INGREZZA or INGREZZA SPRINKLE is coadministered with a strong CYP3A4 inhibitor [see Dosage and Administration ( 2.5 )]. Strong CYP2D6 Inhibitors Clinical Implication: Concomitant use of INGREZZA or INGREZZA SPRINKLE with strong CYP2D6 inhibitors increased the exposure (C max and AUC) to valbenazine’s active metabolite compared with the use of INGREZZA or INGREZZA SPRINKLE alone [see Clinical Pharmacology ( 12.3 , 12.5 )] . Increased exposure of active metabolite may increase the risk of exposure-related adverse reactions [see Warnings and Precautions ( 5.4 )]. Prevention or Management: Reduce INGREZZA or INGREZZA SPRINKLE dose when INGREZZA or INGREZZA SPRINKLE is coadministered with a strong CYP2D6 inhibitor [see Dosage and Administration ( 2.5 )]. Strong CYP3A4 Inducers Clinical Implication: Concomitant use of INGREZZA or INGREZZA SPRINKLE with a strong CYP3A4 inducer decreased the exposure of valbenazine and its active metabolite compared to the use of INGREZZA or INGREZZA SPRINKLE alone. Reduced exposure of valbenazine and its active metabolite may reduce efficacy [see Clinical Pharmacology ( 12.3 )]. Prevention or Management: Concomitant use of strong CYP3A4 inducers with INGREZZA or INGREZZA SPRINKLE is not recommended [see Dosage...

Pregnancy and Breastfeeding
8.1 Pregnancy Risk Summary The limited available data on INGREZZA or INGREZZA SPRINKLE use in pregnant women are insufficient to inform a drug-associated risk. In animal reproductive studies, no malformations were observed when valbenazine was administered orally to rats and rabbits during the period of organogenesis at doses up to 1.8 or 24 times, respectively, the maximum recommended human dose (MRHD) of 80 mg/day based on mg/m 2 body surface area. However, administration of valbenazine to pregnant rats during organogenesis through lactation produced an increase in the number of stillborn pups and postnatal pup mortalities at doses <1 times the MRHD based on mg/m 2 [see Data ]. Advise a pregnant woman of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. The background risk of major birth defects and miscarriage in the U.S. general population is 2 to 4% and 15 to 20% of clinically recognized pregnancies, respectively. Data Animal Data Valbenazine was administered orally to pregnant rats during the period of organogenesis at 1, 5, and 15 mg/kg/day, which are approximately 0.1, 0.6, and 2 times the MRHD of 80 mg/day based on mg/m 2 body surface area. Valbenazine produced a significant decrease in maternal body weight gain at 0.6 and 2 times the MRHD of 80 mg/day based on mg/m 2 . No adverse embryo fetal effects were produced when valbenazine was administered at doses up to 2 times the MRHD of 80 mg/day based on mg/m 2 . Valbenazine was administered orally to pregnant rabbits during the period of organogenesis at 20, 50, and 100 mg/kg/day, which are approximately 5, 12, and 24 times the MRHD of 80 mg/day based on mg/m 2 . No malformations were observed at doses up to 24 times the MRHD of 80 mg/day based on mg/m 2 . However, valbenazine produced a delay in fetal development (decreased fetal...
