INVEGA TRINZA
®
should be used with caution in patients with known cardiovascular
disease (e.g., heart failure, history of myocardial infarction or ischemia, conduction
abnormalities), cerebrovascular disease, or conditions that predispose the patient to
hypotension (e.g., dehydration, hypovolemia, and treatment with antihypertensive
medications). Monitoring of orthostatic vital signs should be considered in patients who
are vulnerable to hypotension.
5.8 Falls
Somnolence, postural hypotension, motor and sensory instability have been reported
with the use of antipsychotics, including INVEGATRINZA
®
, which may lead to falls and,
consequently, fractures or other fall-related injuries. For patients, particularly the
elderly, with diseases, conditions, or medications that could exacerbate these effects,
assess the risk of falls when initiating antipsychotic treatment and recurrently for
patients on long-term antipsychotic therapy.
5.9 Leukopenia, Neutropenia, and Agranulocytosis
In clinical trial and/or postmarketing experience, events of leukopenia and neutropenia
have been reported temporally related to antipsychotic agents, including
INVEGATRINZA
®
. Agranulocytosis has also been reported.
Possible risk factors for leukopenia/neutropenia include pre-existing low white blood
cell count (WBC)/absolute neutrophil count (ANC) and history of drug-induced
leukopenia/neutropenia. In patients with a history of a clinically significant low
WBC/ANC or a drug-induced leukopenia/neutropenia, perform a complete blood count
(CBC) frequently during the first few months of therapy. In such patients, consider
discontinuation of INVEGATRINZA
®
at the first sign of a clinically significant decline in
WBC in the absence of other causative factors.
Monitor patients with clinically significant neutropenia for fever or other symptoms or
signs of infection and treated promptly if such symptoms or signs occur. Discontinue
INVEGA TRINZA
®
in patients with severe neutropenia (absolute neutrophil count
<1000/mm
3
) and follow their WBC until recovery.
5.10 Hyperprolactinemia
Like other drugs that antagonize dopamine D
2
receptors, paliperidone elevates
prolactin levels and the elevation persists during chronic administration. Paliperidone
has a prolactin-elevating effect similar to that seen with risperidone, a drug that is
associated with higher levels of prolactin than other antipsychotic drugs.
Hyperprolactinemia, regardless of etiology, may suppress hypothalamic GnRH, resulting
in reduced pituitary gonadotrophin secretion. This, in turn, may inhibit reproductive
function by impairing gonadal steroidogenesis in both female and male patients.
Galactorrhea, amenorrhea, gynecomastia, and impotence have been reported in
patients receiving prolactin-elevating compounds. Long-standing hyperprolactinemia
when associated with hypogonadism may lead to decreased bone density in both
female and male subjects.
Tissue culture experiments indicate that approximately one-third of human breast
cancers are prolactin dependent in vitro, a factor of potential importance if the
prescription of these drugs is considered in a patient with previously detected breast
cancer. An increase in the incidence of pituitary gland, mammary gland, and pancreatic
islet cell neoplasia (mammary adenocarcinomas, pituitary and pancreatic adenomas)
was observed in the risperidone carcinogenicity studies conducted in mice and rats
[see Nonclinical Toxicology (13.1)]. Neither clinical studies nor epidemiologic studies
conducted to date have shown an association between chronic administration of this
class of drugs and tumorigenesis in humans, but the available evidence is too limited
to be conclusive.
In a long-term maintenance trial of INVEGA TRINZA
®
, elevations of prolactin to above
the reference range (>13.13 ng/mL in males and >26.72 ng/mL in females) relative to
open-label baseline at any time during the double-blind phase were noted in a higher
percentage of males in the INVEGATRINZA
®
group than in the placebo group (46% vs.
25%) and in a higher percentage of females in the INVEGATRINZA
®
group than in the
placebo group (32% vs. 15%). During the double-blind phase, 1 female (2.4%) in the
INVEGA TRINZA
®
group experienced an adverse reaction of amenorrhea, while no
potentially prolactin-related adverse reactions were noted among females in the
placebo group. There were no potentially prolactin-related adverse reactions among
males in either group.
Prior to the double-blind phase (during the 29-week open-label phase of the long-term
maintenance trial), the mean (SD) serum prolactin values at baseline in males (N=368)
were 17.1 (13.55) ng/mL and 51.6 (40.85) ng/mL in females (N=122). Twelve weeks
after a single injection of INVEGA TRINZA
®
at the end of the open-label phase, mean
(SD) prolactin values were 25.8 (13.49) ng/mL in males (N=322) and 70.6 (40.23) ng/mL
in females (N=107). During the open-label phases 27% of females and 42% of males
experienced elevations of prolactin above the reference range relative to baseline, and
a higher proportion of females experienced potentially prolactin-related adverse
reactions compared to males (7.9% vs. 3.7%). Amenorrhea (4.7%) and galactorrhea
(3.1%) were the most commonly observed (≥3%) potentially prolactin-related adverse
reactions in females. Among males in the open-label phase, no potentially prolactin-
related adverse reaction was observed with a rate greater than 3%.
5.11 Potential for Cognitive and Motor Impairment
Somnolence, sedation, and dizziness were reported as adverse reactions in subjects
treated with INVEGA TRINZA
®
[see Adverse Reactions (6.1)]. Antipsychotics, including
INVEGA TRINZA
®
, have the potential to impair judgment, thinking, or motor skills.
Patients should be cautioned about performing activities requiring mental alertness,
such as operating hazardous machinery or operating a motor vehicle, until they are
reasonably certain that paliperidone therapy does not adversely affect them.
5.12 Seizures
In the long-term maintenance trial there were no reports of seizures or convulsions. In
the pivotal clinical studies with the 1-month paliperidone palmitate extended-release
injectable suspension which included four fixed-dose, double-blind, placebo-controlled
studies in subjects with schizophrenia, <1% (1/1293) of subjects treated with the
1-month injection experienced an adverse event of convulsion compared with <1%
(1/510) of placebo-treated subjects who experienced an adverse event of grand mal
convulsion.
Like other antipsychotic drugs, INVEGATRINZA
®
should be used cautiously in patients
with a history of seizures or other conditions that potentially lower the seizure
threshold. Conditions that lower the seizure threshold may be more prevalent in
patients 65 years or older.
5.13 Dysphagia
Esophageal dysmotility and aspiration have been associated with antipsychotic drug
use. INVEGA TRINZA
®
and other antipsychotic drugs should be used cautiously in
patients at risk for aspiration pneumonia.
5.14 Priapism
Drugs with alpha-adrenergic blocking effects have been reported to induce priapism.
Although no cases of priapism have been reported in clinical trials with
INVEGA TRINZA
®
, priapism has been reported with oral paliperidone during
postmarketing surveillance. Severe priapism may require surgical intervention.
5.15 Disruption of Body Temperature Regulation
Disruption of the body’s ability to reduce core body temperature has been attributed to
antipsychotic agents. Appropriate care is advised when prescribing INVEGATRINZA
®
to
patients who will be experiencing conditions which may contribute to an elevation in
core body temperature, e.g., exercising strenuously, exposure to extreme heat, receiving
concomitant medication with anticholinergic activity, or being subject to dehydration.

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.
Patient Exposure
The data described in this section include data from two clinical trials. One is a long-
term maintenance trial, in which 506 subjects with schizophrenia received several
doses of the 1-month paliperidone palmitate extended-release injectable suspension
during the open-label phase, of which 379 subjects continued to receive a single
injection of INVEGA TRINZA
®
during the open-label phase, and 160 subjects were
subsequently randomized to receive at least one dose of INVEGA TRINZA
®
and
145 subjects received placebo during the double-blind placebo-controlled phase. The
mean (SD) duration of exposure during the double-blind phase was 150 (79) days in
the placebo group and 175 (90) days in the INVEGA TRINZA
®
group. The other is a
Phase 1 study (N=308), which included patients with schizophrenia who received a
single injection of INVEGATRINZA
®
concomitantly with other oral antipsychotics.
