6.1 Clinical Studies Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trial of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
The information below is derived from a clinical trial database for Iloperidone consisting of 3,229 patients exposed to Iloperidone at doses of 10 mg/day or greater, for the treatment of schizophrenia of these, 999 received Iloperidone for at least 6 months, with 657 exposed to Iloperidone for at least 12 months for the treatment of schizophrenia.
All of these patients who received Iloperidone were participating in multiple-dose clinical trials.
The conditions and duration of treatment with Iloperidone varied greatly and included (in overlapping categories), open-label and double-blind phases of studies, inpatients and outpatients, fixed-dose and flexible-dose studies, and short-term and longer-term exposure.
Schizophrenia The information presented in this section was derived from pooled data from 4 placebo-controlled, 4- or 6- week, fixed- or flexible-dose studies in patients who received Iloperidone at daily doses within a range of 10 to 24 mg (n=874).
Adverse Reactions Occurring at an Incidence of 2% or More among Iloperidone-Treated Patients and More Frequent than Placebo Table 3 enumerates the pooled incidences of adverse reactions that were spontaneously reported in four placebo-controlled, 4- or 6-week, fixed- or flexible-dose studies, listing those reactions that occurred in 2% or more of patients treated with Iloperidone in any of the dose groups, and for which the incidence in Iloperidone- treated patients in any dose group was greater than the incidence in patients treated with placebo.
Table 3: Percentage of Adverse Reactions in Short-Term, Fixed- or Flexible-Dose, Placebo- Controlled Schizophrenia Trials in Adult Patients Table includes adverse reactions that were reported in 2% or more of patients in any of the iloperidone tablets dose groups and which occurred at greater incidence than in the placebo group.

Common and Drug-Related Adverse Reactions in Clinical Trials Based on the pooled data from 4 placebo-controlled, 4- or 6-week, fixed- or flexible-dose studies of patients with schizophrenia, the following adverse reactions occurred in ≥5% incidence in the patients treated with Iloperidone and at least twice the placebo rate for at least 1 dose: dizziness, dry mouth, fatigue, nasal congestion, somnolence, tachycardia, orthostatic hypotension, and weight increased.
Dizziness, tachycardia, and weight increased were at least twice as common on 20-24 mg/day as on 10-16 mg/day.
Extrapyramidal Symptoms (EPS) in Clinical Trials Pooled data from the 4 placebo-controlled, 4- or 6-week, fixed- or flexible-dose studies of patients with schizophrenia provided information regarding EPS.
Adverse event data collected from those trials showed the following rates of EPS-related adverse events as shown in Table 5.
Table 5: Percentage of EPS Compared to Placebo in 4- or 6-week Schizophrenia Trials Placebo (%) Iloperidone Tablets 10 to 16 mg/day (%) Iloperidone Tablets 20 to 24 mg/day (%) Preferred Term (N = 587) (N = 483) (N = 391) All EPS events 11.6 13.5 15.1 Tremor Akathisia 1.9 2.7 2.5 1.7 3.1 2.3 Bradykinesia 0 0.6 0.5 Dyskinesia 1.5 1.7 1.0 Dystonia 0.7 1.0 0.8 Parkinsonism 0 0.2 0.3 Adverse Reactions Associated with Discontinuation of Treatment in Clinical Trials Based on the pooled data from 4 placebo-controlled, 4- or 6-week, fixed- or flexible-dose studies in patients with schizophrenia, there was no difference in the incidence of discontinuation due to adverse reactions between Iloperidone-treated (5%) and placebo-treated (5%) patients.
The types of adverse reactions that led to discontinuation were similar for the Iloperidone- and placebo-treated patients.
Demographic Differences in Adverse Reactions in Clinical Trials An examination of population subgroups in the 4 placebo-controlled, 4- or 6-week, fixed- or flexible-dose studies of patients with schizophrenia did not reveal any evidence of differences in safety on the basis of age, sex or race.
Laboratory Test Abnormalities in Clinical Trials There were no differences between Iloperidone and placebo in the incidence of discontinuation due to changes in hematology, or urinalysis.
Hematocrit In short-term placebo-controlled trials (4- to 6-weeks) in patients with schizophrenia, there were 1.0% (13/1342) Iloperidone-treated patients with hematocrit at least one time below the extended normal range during post-randomization treatment, compared to 0.3% (2/585) on placebo.
The extended normal range for lowered hematocrit was defined in each of these trials as the value 15% below the normal range for the centralized laboratory that was used in the trial.
Analysis of clinical laboratory data following administration of Iloperidone suggested the mechanism of hemodilution based on consistent decreases in hematocrit, hemoglobin, white blood cells, total protein, and albumin.
Decreases in hematocrit and total protein have been observed with other alpha receptor antagonists and are attributed to hemodilution [see Clinical Pharmacology (12.2)].
Other Reactions During the Pre-marketing Evaluation of Iloperidone Patients with Schizophrenia The following is a list of MedDRA terms that reflect adverse reactions in patients treated with Iloperidone at multiple doses ≥ 4 mg/day during any phase of a trial with the database of 3,210 Iloperidone-treated patients with schizophrenia.
All reported reactions are included except those already listed in Table 3, or other parts of the Adverse Reactions (6), those considered in the Warnings and Precautions (5), those reaction terms which were so general as to be uninformative, reactions reported in fewer than 3 patients and which were neither serious nor life-threatening, reactions that are otherwise common as background reactions, and reactions considered unlikely to be drug related.
Reactions are further categorized by MedDRA system organ class and listed in order of decreasing frequency according to the following definitions: frequent adverse events are those occurring in at least 1/100 patients (only those not listed in Table 3 appear in this listing); infrequent adverse reactions are those occurring in 1/100 to 1/1000 patients; rare events are those occurring in fewer than 1/1000 patients.

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency or establish a causal relationship to drug exposure: retrograde ejaculation and hypersensitivity reactions (including anaphylaxis; angioedema; throat tightness; oropharyngeal swelling; swelling of the face, lips, mouth, and tongue; urticaria; rash; and pruritus).
