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 safety of CAPLYTA has been evaluated in placebo-controlled clinical trials that included 3575 adult patients with schizophrenia, bipolar depression, or major depressive disorder, exposed to one or more CAPLYTA doses. A total of 852 CAPLYTA-treated patients had at least 6 months of treatment and 108 had at least 1 year of treatment with the 42-mg once daily dosage.
Adverse Reactions in Patients with Schizophrenia
The following adverse reactions are based on the pooled short-term (4- to 6-week), placebo-controlled studies in adult patients with schizophrenia in which CAPLYTA was administered at a dosage of 42 mg once daily (N=406) [see Clinical Studies (14.1)].
There was no single adverse reaction that led to discontinuation that occurred at a rate of >2% in CAPLYTA-treated patients. The most common adverse reactions (incidence of at least 5% of CAPLYTA-treated patients and greater than twice the rate of placebo-treated patients) were somnolence/sedation and dry mouth. Adverse reactions (incidence of at least 2% in CAPLYTA-treated patients and greater than in placebo-treated patients) are shown in Table 2.

Adverse Reactions in Studies for Adjunctive Treatment of Major Depressive Disorder
The following adverse reactions are based on pooled short-term (6-week), placebo-controlled adjunctive therapy MDD studies in adult patients treated with CAPLYTA 42 mg orally once daily and background antidepressant therapy (ADT) or placebo and background ADT (N=483) [see Clinical Studies (14.3)].
There was no single adverse reaction leading to discontinuation that occurred at an incidence of >2% in patients treated with CAPLYTA and background ADT.
The most common adverse reactions (incidence of at least 5% of patients treated with CAPLYTA and background ADT and greater than twice the incidence in patients treated with placebo and background ADT) were dizziness, dry mouth, somnolence/sedation, nausea, fatigue, and diarrhea.

Additional Adverse Reactions
Dystonia: Symptoms of dystonia, prolonged abnormal contractions of muscle groups, may occur in susceptible individuals during the first few days of treatment. Dystonic symptoms include: spasm of the neck muscles, sometimes progressing to tightness of the throat, swallowing difficulty, difficulty breathing, and/or protrusion of the tongue. Although these symptoms can occur at low doses, they occur more frequently and with greater severity with high potency and higher doses of first-generation antipsychotic drugs. An elevated risk of acute dystonia is observed in males and younger age groups.
Extrapyramidal Symptoms: In the short-term, placebo-controlled schizophrenia, bipolar depression, and adjunctive MDD studies, extrapyramidal (EPS) symptom data was objectively collected on the Simpson-Angus Scale (SAS) for EPS (total score ranges from 0 to 40), the Barnes Akathisia Rating Scale (BARS) for akathisia (total score ranges from 0 to 14), and the Abnormal Involuntary Movement Scale (AIMS) for dyskinesia (total score ranges from 0 to 28).
- In the 4- to 6-week, placebo-controlled schizophrenia trials, the frequency of EPS-related reported events including akathisia, extrapyramidal disorder, muscle spasms, restlessness, musculoskeletal stiffness, dyskinesia, dystonia, muscle twitching, tardive dyskinesia, tremor, drooling, and involuntary muscle contractions was 6.7% for the CAPLYTA-treated patients and 6.3% for placebo-treated patients. In these trials, the mean changes from baseline for CAPLYTA-treated patients and placebo-treated patients were 0.1 and 0 for the SAS, -0.1 and 0 for the BARS, and 0.1 and 0 for the AIMS, respectively.
- In the 6-week, monotherapy bipolar depression trials, the frequency of reported EPS-related reactions including muscle spasms, dyskinesia, extrapyramidal disorder, movement disorder, tremor, restlessness, and akathisia was 1.3% for CAPLYTA-treated patients and 1.1% for placebo-treated patients. In these trials, the mean changes from baseline for CAPLYTA-treated patients and placebo-treated patients were 0 and 0 for the SAS, -0.1 and -0.1 for the BARS, and 0 and 0 for the AIMS, respectively.
- In a 6-week, adjunctive therapy bipolar depression trial, the frequency of reported EPS-related reactions, including tremor, muscle spasms, akathisia, extrapyramidal disorder, gait disturbance, and restlessness was 4% for CAPLYTA-treated patients and 2.3% for placebo-treated patients. In the 6-week, monotherapy bipolar depression trials, the mean changes from baseline for CAPLYTA-treated patients and placebo-treated patients were 0 and 0 for the SAS, -0.1 and -0.1 for the BARS, and 0 and 0 for the AIMS, respectively. In this trial, the mean changes from baseline for CAPLYTA-treated patients and placebo-treated patients were 0 and 0 for the SAS, 0 and -0.1 for the BARS, and 0 and 0 for the AIMS, respectively.
- In the 6-week, adjunctive MDD trials, the frequency of reported EPS-related adverse reactions (tremor, bradykinesia, muscle spasms, gait disturbance, tongue spasm, muscle tightness and dyskinesia), excluding akathisia and restlessness, was 5% for CAPLYTA-treated patients and 0.8% for placebo-treated patients. The combined incidence of akathisia and restlessness was 1% for CAPLYTA-treated patients and 0.8% for placebo-treated patients. In these trials, the mean changes from baseline for CAPLYTA-treated patients and placebo-treated patients were 0 and 0 for the SAS, 0 and -0.1 for the BARS, and 0 and 0 for the AIMS, respectively.
