6.1 Clinical Trials Experience 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 clinical practice.

The safety of ERZOFRI for the treatment of schizophrenia in adults and schizoaffective disorder in adults as monotherapy and as an adjunct to mood stabilizers or antidepressants is based upon adequate and well-controlled studies of another once-a-month paliperidone palmitate extended-release injectable suspension (also referred to as "PP1M" in this section).

Below is a display of adverse reactions with another PP1M from those adequate and well-controlled studies.

Injection site reactions for ERZOFRI presented in this section (see " Pain and Injection Site Reactions with ERZOFRI " below) are based on pharmacokinetic studies.

Patient Exposure The data described in this section are derived from a clinical trial database consisting of a total of 3,817 subjects (approximately 1,705 patient-years exposure) with schizophrenia who received at least one dose of PP1M in the recommended dose range of 39 mg to 234 mg and a total of 510 subjects with schizophrenia who received placebo.

Among the 3,817 PP1M-treated subjects, 1,293 received PP1M in four fixed-dose, double- blind, placebo-controlled trials (one 9-week and three 13-week studies), 849 received PP1M in the maintenance trial (median exposure 229 days during the initial 33-week open-label phase of this study, of whom 205 continued to receive PP1M during the double-blind placebo-controlled phase of this study [median exposure 171 days]), and 1,675 received PP1M in five non-placebo controlled trials (three noninferiority active- comparator trials, one long-term open-label pharmacokinetic and safety study, and an injection site [deltoid-gluteal] cross-over trial).

One of the 13-week studies included a 234 mg PP1M initiation dose followed by treatment with either 39 mg, 156 mg, or 234 mg every 4 weeks.

The safety of PP1M was also evaluated in a 15-month, long-term study comparing the other PP1M to selected oral antipsychotic therapies in adult subjects with schizophrenia.

A total of 226 subjects received PP1M during the 15-month, open-label period of this study; 218 subjects received selected oral antipsychotic therapies.

The safety of PP1M was similar to that seen in previous double-blind, placebo-controlled clinical trials in adult subjects with schizophrenia.

The safety of PP1M was also evaluated in a long-term study in adult subjects with schizoaffective disorder.

A total of 667 subjects PP1M during the initial 25-week open-label period of this study (median exposure 147 days); 164 subjects continued to receive PP1M during the 15-month double-blind placebo-controlled period of this study (median exposure 446 days).

Adverse reactions that occurred more frequently in the PP1M group than the placebo group (a 2% difference or more between groups) were weight increased, nasopharyngitis, headache, hyperprolactinemia, and pyrexia.

Adverse Reactions in Double-Blind, Placebo-Controlled Clinical Trials Commonly Observed Adverse Reactions : The most common (at least 5% in any PP1M group) and likely drug-related (adverse events for which the drug rate is at least twice the placebo rate) adverse reactions from the double-blind, placebo-controlled trials in subjects with schizophrenia were injection site reactions, somnolence/sedation, dizziness, akathisia, and extrapyramidal disorder .

No occurrences of adverse events reached this threshold in the long-term double-blind, placebo-controlled study in subjects with schizoaffective disorder.

Discontinuation of Treatment Due to Adverse Events : The percentage of subjects who discontinued due to adverse events in the four fixed-dose, double-blind, placebo-controlled schizophrenia trials were similar for PP1M- and placebo-treated subjects.

The percentage of subjects who discontinued due to adverse events in the open-label period of the long-term study in subjects with schizoaffective disorder was 7.5%.

During the double-blind, placebo-controlled period of that study, the percentages of subjects who discontinued due to adverse events were 5.5% and 1.8% in PP1M- and placebo-treated subjects, respectively.

Dose-Related Adverse Reactions : Based on the pooled data from the four fixed-dose, double- blind, placebo-controlled trials in subjects with schizophrenia, among the adverse reactions that occurred with ≥ 2% incidence in the subjects treated with PP1M, only akathisia increased with dose.

Hyperprolactinemia also exhibited a dose relationship, but did not occur at ≥ 2% incidence in PP1M-treated subjects from the four fixed-dose studies.

Adverse Reactions Occurring at an Incidence of 2% or More in a once-a-month paliperidone palmitate extended-release injectable suspension-Treated Patients: Table 9 lists the adverse reactions reported in 2% or more of PP1M -treated subjects and at a greater proportion than in the placebo group with schizophrenia in the four fixed-dose, double-blind, placebo-controlled trials.

Extrapyramidal Symptoms (EPS) Pooled data from the two double-blind, placebo-controlled, 13-week, fixed-dose trials in adult subjects with schizophrenia provided information regarding EPS.

Several methods were used to measure EPS: (1) the Simpson-Angus global score which broadly evaluates parkinsonism, (2) the Barnes Akathisia Rating Scale global clinical rating score which evaluates akathisia, (3) the Abnormal Involuntary Movement Scale scores which evaluates dyskinesia, and (4) use of anticholinergic medications to treat EPS (Table 10), and (5) incidence of spontaneous reports of EPS (Table 11).

In the 9-week, fixed-dose, double-blind, placebo-controlled trial, the proportions of parkinsonism and akathisia assessed by incidence of rating scales were higher in the PP1M 156 mg group (18% and 11%, respectively) than in the PP1M 78 mg group (9% and 5%, respectively) and placebo group (7% and 4%, respectively).

In the 13-week study in subjects with schizophrenia involving 234 mg initiation dosing, the incidence of any EPS was similar to that of the placebo group (8%), but exhibited a dose-related pattern with 6%, 10%, and 11% in the PP1M 234/39 mg, 234/156 mg, and 234/234 mg groups, respectively.

Hyperkinesia was the most frequent category of EPS-related adverse events in this study, and was reported at a similar rate between the placebo (4.9%) and PP1M 234/156 mg (4.8%) and 234/234 mg (5.5%) groups, but at a lower rate in the 234/39 mg group (1.3%).

In the long-term study in subjects with schizoaffective disorder, EPS reported during the 25-week open-label PP1M treatment included hyperkinesia (12.3%), parkinsonism (8.7%), tremor (3.4%), dyskinesia (2.5%), and dystonia (2.1%).

During the 15-month double-blind treatment, the incidence of any EPS was similar to that of the placebo group (8.5% and 7.1% respectively).

The most commonly reported treatment-emergent EPS-related adverse events (> 2%) in any treatment group in the double-blind phase of the study (PP1M versus placebo) were hyperkinesia (3.7% versus 2.9%), parkinsonism (3.0% versus 1.8%), and tremor (1.2% versus 2.4%).

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.

While these symptoms can occur at low doses, they occur more frequently and with greater severity with high potency and at higher doses of first-generation antipsychotic drugs.

An elevated risk of acute dystonia is observed in males and younger age groups.

Pain Assessment and Injection Site Reactions In the pooled data from the two 13-week, fixed-dose, double-blind, placebo-controlled trials of another PP1M in subjects with schizophrenia, the mean intensity of injection pain reported by subjects using a visual analog scale (0 = no pain to 100 = unbearably painful) decreased in all treatment groups from the first to the last injection (placebo: 10.9 to 9.8; 39 mg: 10.3 to 7.7; 78 mg: 10.0 to 9.2; 156 mg: 11.1 to 8.8).

The results from both the 9-week, fixed-dose, double-blind, placebo-controlled trial and the double-blind phase of the maintenance trial exhibited comparable findings.

In the 13-week study involving 234 mg initiation dosing in subjects with schizophrenia, occurrences of induration, redness, or swelling, as assessed by blinded study personnel, were infrequent, generally mild, decreased over time, and similar in incidence between the PP1M and placebo groups.

Investigator ratings of injection pain were similar for the placebo and PP1M groups.

Investigator evaluations of the injection site after the first injection for redness, swelling, induration, and pain were rated as absent for 69-100% of subjects in both the PP1M and placebo groups.

At Day 92, investigators rated absence of redness, swelling, induration, and pain in 95-100% of subjects in both the PP1M and placebo groups.

ERZOFRI was evaluated in 281 patients with schizophrenia or schizoaffective disorder in an open-label randomized parallel arm study.

The percentage of patients in the open-label study reporting injection site-related adverse reactions at the first injection for patients treated with ERZOFRI (all reported as injection site pain) was similar to the percentage of patients treated with another PP1M.

Additional Adverse Reactions Reported in Clinical Trials with Oral Paliperidone The following is a list of additional adverse reactions that have been reported in clinical trials with oral paliperidone: Cardiac disorders : bundle branch block left, sinus arrhythmia Gastrointestinal disorders : abdominal pain, small intestinal obstruction General disorders and administration site conditions : edema, edema peripheral Immune system disorders : anaphylactic reaction Infections and infestations: rhinitis Musculoskeletal and connective tissue disorders : musculoskeletal pain, torticollis, trismus Nervous system disorders : grand mal convulsion, parkinsonian gait, transient ischemic attack Psychiatric disorders: sleep disorder Reproductive system and breast disorders : breast engorgement Respiratory, thoracic and mediastinal disorders: pharyngolaryngeal pain, pneumonia aspiration Skin and subcutaneous tissue disorders: rash papular Vascular disorders: hypotension, ischemia 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of paliperidone; because these reactions were reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure: angioedema, catatonia, ileus, somnambulism, swollen tongue, thrombotic thrombocytopenic purpura, urinary incontinence, and urinary retention.

Cases of anaphylactic reaction after injection with another once-a-month paliperidone palmitate extended-release injectable suspension product have been reported during postmarketing experience in patients who have previously tolerated oral risperidone or oral paliperidone.

Paliperidone is the major active metabolite of risperidone.

Adverse reactions reported with oral risperidone and risperidone long-acting injection can be found in the Adverse Reactions (6) sections of the package inserts for those products.
