In an uncontrolled open-label trial of CAPLYTA for up to 1 year in adult patients with stable schizophrenia, the percentages of patients with shifts in fasting glucose and insulin values from normal to high were 8% and 12%, respectively.
In data from short-term (6-week), placebo-controlled monotherapy and adjunctive therapy bipolar depression trials, mean changes from baseline and the proportion of patients with shifts from normal to greater than normal levels of fasting glucose and insulin were similar in CAPLYTA-treated and placebo-treated patients.
