`
`WARNING: INCREASED MORTALITY IN ELDERLY PATIENTS WITH DEMENTIA-
`RELATED PSYCHOSIS
`Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an
`increased risk of death. INVEGA SUSTENNA® is not approved for use in patients with
`dementia-related psychosis. [see Warnings and Precautions (5.1)].
`
` 1
`
`INDICATIONS AND USAGE
`
`INVEGA SUSTENNA® (paliperidone palmitate) is indicated for the treatment of:
`• Schizophrenia in adults [see Clinical Studies (14.1)].
`• Schizoaffective disorder in adults as monotherapy and as an adjunct to mood stabilizers or
`antidepressants [see Clinical Studies (14.2)].
`
`2 DOSAGE AND ADMINISTRATION
`2.1 Administration Instructions
`Each injection must be administered only by a healthcare professional.
`
`Parenteral drug products should be inspected visually for foreign matter and discoloration prior
`to administration, whenever product and container permit.
`
`INVEGA SUSTENNA® is intended for intramuscular use only. Do not administer by any other
`route. Avoid inadvertent injection into a blood vessel. Administer the dose in a single injection;
`do not administer the dose in divided injections. Inject slowly, deep into the deltoid or gluteal
`muscle.
`
`INVEGA SUSTENNA® must be administered using only the needles that are provided in the
`INVEGA SUSTENNA® kit.
`
`The recommended needle size for administration of INVEGA SUSTENNA® into the deltoid
`muscle is determined by the patient’s weight:
`
`• For patients weighing less than 90 kg, the 1-inch, 23 gauge needle is recommended.
`
`• For patients weighing 90 kg or more, the 1½-inch, 22 gauge needle is recommended.
`
`Deltoid injections should be alternated between the two deltoid muscles.
`
`The recommended needle size for administration of INVEGA SUSTENNA® into the gluteal
`muscle is the 1½-inch, 22 gauge needle regardless of patient weight.
`
`Administer into the upper-outer quadrant of the gluteal muscle. Gluteal injections should be
`alternated between the two gluteal muscles.

`
`Reference ID: 4298398
`
`
`
`
`2.2 Schizophrenia and Schizoaffective Disorder
`For patients who have never taken oral paliperidone or oral or injectable risperidone, it is
`recommended to establish tolerability with oral paliperidone or oral risperidone prior to initiating
`treatment with INVEGA SUSTENNA®.
`
`The recommended dosing of INVEGA SUSTENNA® for each approved indication is displayed
`in Table 1. The recommended initiation of INVEGA SUSTENNA® is with a dose of 234 mg on
`treatment day 1 and 156 mg one week later, both administered in the deltoid muscle. Following
`the second initiation dose, monthly maintenance doses can be administered in either the deltoid
`or gluteal muscle.

`The recommended maintenance dose for treatment of schizophrenia is 117 mg. Some patients may benefit from
`lower or higher maintenance doses within the additional available strengths (39 mg, 78 mg, 156 mg, and
`234 mg).
`c Adjust dose based on tolerability and/or efficacy using available strengths. The 39 mg strength was not studied
`in the long-term schizoaffective disorder study.
`
`
`Adjustment of the maintenance dose may be made monthly. When making dose adjustments, the
`prolonged-release characteristics of INVEGA SUSTENNA® should be considered [see Clinical
`Pharmacology (12.3)], as the full effect of the dose adjustment may not be evident for several
`months.
`
`2.3 Missed Doses
`Avoiding Missed Doses
`It is recommended that the second initiation dose of INVEGA SUSTENNA® be given one week
`after the first dose. To avoid a missed dose, patients may be given the second dose 4 days before
`or after the one-week time point. Similarly, the third and subsequent injections after the initiation
`regimen are recommended to be given monthly. To avoid a missed monthly dose, patients may
`be given the injection up to 7 days before or after the monthly time point.
`
`Reference ID: 4298398
`
`4
`
`
`
`
`
`Management of a Missed Second Initiation Dose
`If the target date for the second INVEGA SUSTENNA® injection (one week ± 4 days) is missed,
`the recommended reinitiation depends on the length of time which has elapsed since the patient's
`first injection. In case of a missed second initiation dose follow the dosing instructions provided
`in Table 2.
`

`
`DOSING
`
`4 to 7 weeks since first injection
`
`Administer the second initiation dose of 156 mg in the deltoid
`muscle as soon as possible.
`1.
`It is recommended to administer a third injection of 117 mg in
`either the deltoid or gluteal muscle 5 weeks after the first injection
`(regardless of the timing of the second injection).
`2. Thereafter, resume regular monthly dosing in either the deltoid or
`gluteal muscle.
`Resume dosing with two injections of 156 mg in the following
`manner:
`1. Administer a deltoid injection as soon as possible.
`2. Administer a second deltoid injection 1 week later.
`3. Thereafter, resume regular monthly dosing in either the
`deltoid or gluteal muscle.
`More than 7 weeks since first injection Restart dosing with recommended initiation (see Section 2.2,
`Table 1):
`1. Administer a 234 mg deltoid injection on Day 1.
`2. Administer a 156 mg deltoid injection 1 week later.
`3. Thereafter, resume regular monthly dosing in either the
`deltoid or gluteal muscle.

`intervals.
`Resume the same dose the patient was previously stabilized on
`(unless the patient was stabilized on a dose of 234 mg, then the first
`2 injections should each be 156 mg) in the following manner:
`1. Administer a deltoid injection as soon as possible.
`2. Administer a second deltoid injection 1 week later at the same
`dose.
`3. Thereafter, resume administering the previously stabilized
`dose in the deltoid or gluteal muscle 1 month after the second
`injection.
`More than 6 months since last injection Restart dosing with recommended initiation (see Section 2.2,
`Table 1):
`1. Administer a 234 mg deltoid injection on Day 1.
`2. Administer a 156 mg deltoid injection 1 week later.
`3. Thereafter, resume administering the previously stabilized
`dose in the deltoid or gluteal muscle 1 month after the second
`injection.
`
`
`
`2.4 Use with Risperidone or with Oral Paliperidone
`Since paliperidone is the major active metabolite of risperidone, caution should be exercised
`when INVEGA SUSTENNA® is coadministered with risperidone or with oral paliperidone for
`extended periods of time. Safety data involving concomitant use of INVEGA SUSTENNA® with
`other antipsychotics is limited.
`
`2.5 Dosage Adjustments
`Renal Impairment
`INVEGA SUSTENNA® has not been systematically studied in patients with renal impairment
`[see Clinical Pharmacology (12.3)]. For patients with mild renal impairment (creatinine
`clearance ≥ 50 mL/min to < 80 mL/min [Cockcroft-Gault Formula]), initiate INVEGA
`SUSTENNA® with a dose of 156 mg on treatment day 1 and 117 mg one week later. Administer
`both doses in the deltoid muscle. Thereafter, follow with monthly injections of 78 mg in either
`the deltoid or gluteal muscle [see Use in Specific Populations (8.6) and Clinical Pharmacology
`(12.3)].
`
`INVEGA SUSTENNA® is not recommended in patients with moderate or severe renal
`
`6
`
`
`Reference ID: 4298398
`
`
`
`
`impairment (creatinine clearance < 50 mL/min) [see Use in Specific Populations (8.6) and
`Clinical Pharmacology (12.3)].
`
`Coadministration with Strong CYP3A4/P-glycoprotein (P-gp) Inducers
`Avoid using a strong inducer of CYP3A4 and/or P-gp (e.g., carbamazepine, rifampin, St John’s
`Wort) during the 1-month dosing interval for INVEGA SUSTENNA®, if possible. If
`administering a strong inducer is necessary, consider managing the patient using paliperidone
`extended release tablets [see Drug Interactions (7.1) and Clinical Pharmacology (12.3)].
`
`Switching from Other Antipsychotics
`2.6
`There are no systematically collected data to specifically address switching patients with
`schizophrenia or schizoaffective disorder from other antipsychotics to INVEGA SUSTENNA®,
`or concerning concomitant administration with other antipsychotics.
`
`Switching from Oral Antipsychotics
`For patients who have never taken oral paliperidone or oral or injectable risperidone, tolerability
`should be established with oral paliperidone or oral risperidone prior to initiating treatment with
`INVEGA SUSTENNA®.
`
`Previous oral antipsychotics can be gradually discontinued at the time of initiation of treatment
`with INVEGA SUSTENNA®. Recommended initiation of INVEGA SUSTENNA® is with a
`dose of 234 mg on treatment day 1 and 156 mg one week later, both administered in the deltoid
`muscle [see Dosage and Administration (2.2)]. Patients previously stabilized on different doses
`of INVEGA® Extended-Release tablets can attain similar paliperidone steady-state exposure
`during maintenance treatment with INVEGA SUSTENNA® monthly doses as depicted in
`Table 4.

`INVEGA SUSTENNA®.
`
`Reference ID: 4298398
`
`7
`
`
`
`
`
`When switching patients currently at steady-state on a long-acting injectable antipsychotic,
`initiate INVEGA SUSTENNA® therapy in place of the next scheduled injection. INVEGA
`SUSTENNA® should then be continued at monthly intervals. The one-week initiation dosing
`regimen as described in Section 2.2 is not required. See Table 1 above for recommended
`monthly maintenance dosing. Based on previous clinical history of tolerability and/or efficacy,
`some patients may benefit from lower or higher maintenance doses within the available strengths
`(39 mg, 78 mg, 117 mg, 156 mg, and 234 mg). The 39 mg strength was not studied in the
`long-term schizoaffective disorder study. Monthly maintenance doses can be administered in
`either the deltoid or gluteal muscle [see Dosage and Administration (2.2)].
`
`If INVEGA SUSTENNA® is discontinued, its prolonged-release characteristics must be
`considered. As recommended with other antipsychotic medications, the need for continuing
`existing extrapyramidal symptoms (EPS) medication should be re-evaluated periodically.
`
`Instructions for Use
`2.7
`Each injection must be administered only by a healthcare professional.
`
`The kit contains a prefilled syringe and 2 safety needles (a 1 ½-inch 22 gauge needle and a
`1-inch 23 gauge needle) for intramuscular injection.
`
`INVEGA SUSTENNA® is for single use only.
`
`
`
`
`
`a. Shake the syringe vigorously for a minimum of 10 seconds to ensure a homogeneous
`suspension.
`

`
`
`Reference ID: 4298398
`
`
`
`
`
`b. Select the appropriate needle.
`
`For DELTOID injection:
`
`
`
`•
`
`•
`
`If the patient weighs less than 90 kg, use the 1-inch 23 gauge needle (needle with blue
`colored hub).
`
`If the patient weighs 90 kg or more, use the 1 ½-inch 22 gauge needle (needle with gray
`colored hub).
`
`For GLUTEAL injection:
`
`Use the 1 ½-inch 22 gauge needle (needle with gray colored hub) regardless of patient’s
`weight.
`
`
`
`c. While holding the syringe upright, remove the rubber tip cap with an easy clockwise twisting
`motion.
`
`
`

`
`
`
`
`f. Bring the syringe with the attached needle in upright position to de-aerate. De-aerate the
`syringe by moving the plunger rod carefully forward.
`
`
`
`g. Inject the entire contents intramuscularly slowly, deep into the selected deltoid or gluteal
`muscle of the patient. Do not administer by any other route.
`
`h. After the injection is complete, use either thumb or finger of one hand (h1, h2) or a flat
`surface (h3) to activate the needle protection system. The needle protection system is fully
`activated when a ‘click’ is heard. Discard the syringe with needle appropriately.

`
`3 DOSAGE FORMS AND STRENGTHS
`INVEGA SUSTENNA® is available as a white to off-white aqueous extended-release injectable
`suspension for intramuscular injection in dose strengths of 39 mg, 78 mg, 117 mg, 156 mg, and
`234 mg paliperidone palmitate.
`
`4 CONTRAINDICATIONS
`INVEGA SUSTENNA® is contraindicated in patients with a known hypersensitivity to either
`paliperidone or risperidone, or to any of the excipients in the INVEGA SUSTENNA®
`formulation. Hypersensitivity reactions, including anaphylactic reactions and angioedema, have
`been reported in patients treated with risperidone and in patients treated with paliperidone.
`Paliperidone palmitate is converted to paliperidone, which is a metabolite of risperidone.
`
`5 WARNINGS AND PRECAUTIONS
`5.1
`Increased Mortality in Elderly Patients with Dementia-Related Psychosis
`Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an
`increased risk of death. Analyses of 17 placebo-controlled trials (modal duration of 10 weeks),
`
`12
`
`
`Reference ID: 4298398
`
`
`
`
`largely in patients taking atypical antipsychotic drugs, revealed a risk of death in drug-treated
`patients of between 1.6 to 1.7 times the risk of death in placebo-treated patients. Over the course
`of a typical 10-week controlled trial, the rate of death in drug-treated patients was about 4.5%,
`compared to a rate of about 2.6% in the placebo group. Although the causes of death were
`varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death)
`or infectious (e.g., pneumonia) in nature. Observational studies suggest that, similar to atypical
`antipsychotic drugs, treatment with conventional antipsychotic drugs may increase mortality.
`The extent to which the findings of increased mortality in observational studies may be attributed
`to the antipsychotic drug as opposed to some characteristic(s) of the patients is not clear.
`INVEGA SUSTENNA® is not approved for the treatment of patients with dementia-related
`psychosis [see Boxed Warning and Warnings and Precautions (5.2)].
`
`5.2 Cerebrovascular Adverse Reactions, Including Stroke, in Elderly Patients
`with Dementia-Related Psychosis
`In placebo-controlled trials with risperidone, aripiprazole, and olanzapine in elderly subjects with
`dementia, there was a higher incidence of cerebrovascular adverse reactions (cerebrovascular
`accidents and transient ischemic attacks) including fatalities compared to placebo-treated
`subjects. No studies have been conducted with oral paliperidone, INVEGA SUSTENNA®, or the
`3-month paliperidone palmitate extended-release injectable suspension in elderly patients with
`dementia. These medicines are not approved for the treatment of patients with dementia-related
`psychosis [see Boxed Warning and Warnings and Precautions (5.1)].
`
`5.3 Neuroleptic Malignant Syndrome
`A potentially fatal symptom complex sometimes referred to as Neuroleptic Malignant Syndrome
`(NMS) has been reported in association with antipsychotic drugs, including paliperidone.
`
`Clinical manifestations of NMS are hyperpyrexia, muscle rigidity, altered mental status, and
`evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis,
`and cardiac dysrhythmia). Additional signs may include elevated creatine phosphokinase,
`myoglobinuria (rhabdomyolysis), and acute renal failure.
`
`The diagnostic evaluation of patients with this syndrome is complicated. In arriving at a
`diagnosis, it is important to identify cases in which the clinical presentation includes both serious
`medical illness (e.g., pneumonia, systemic infection, etc.) and untreated or inadequately treated
`extrapyramidal signs and symptoms (EPS). Other important considerations in the differential
`diagnosis include central anticholinergic toxicity, heat stroke, drug fever, and primary central
`nervous system pathology.
`
`The management of NMS should include: (1) immediate discontinuation of antipsychotic drugs
`

`
`
`
`
`and other drugs not essential to concurrent therapy; (2) intensive symptomatic treatment and
`medical monitoring; and (3) treatment of any concomitant serious medical problems for which
`specific treatments are available. There is no general agreement about specific pharmacological
`treatment regimens for uncomplicated NMS.
`
`If a patient appears to require antipsychotic drug treatment after recovery from NMS,
`reintroduction of drug therapy should be closely monitored, since recurrences of NMS have been
`reported.
`
`5.4 QT Prolongation
`Paliperidone causes a modest increase in the corrected QT (QTc) interval. The use of
`paliperidone should be avoided in combination with other drugs that are known to prolong QTc
`including Class 1A (e.g., quinidine, procainamide) or Class III (e.g., amiodarone, sotalol)
`antiarrhythmic medications, antipsychotic medications (e.g., chlorpromazine, thioridazine),
`antibiotics (e.g., gatifloxacin, moxifloxacin), or any other class of medications known to prolong
`the QTc interval. Paliperidone should also be avoided in patients with congenital long QT
`syndrome and in patients with a history of cardiac arrhythmias.
`
`Certain circumstances may increase the risk of the occurrence of Torsades de pointes and/or
`sudden death in association with the use of drugs that prolong the QTc interval, including
`(1) bradycardia; (2) hypokalemia or hypomagnesemia; (3) concomitant use of other drugs that
`prolong the QTc interval; and (4) presence of congenital prolongation of the QT interval.
`
`The effects of oral paliperidone on the QT interval were evaluated in a double-blind,
`active-controlled (moxifloxacin 400 mg single dose), multicenter QT study in adults with
`schizophrenia and schizoaffective disorder, and in three placebo- and active-controlled 6-week,
`fixed-dose efficacy trials in adults with schizophrenia.
`
`In the QT study (n=141), the 8 mg dose of immediate-release oral paliperidone (n=50) showed a
`mean placebo-subtracted increase from baseline in QTcLD of 12.3 msec (90% CI: 8.9; 15.6) on
`day 8 at 1.5 hours post-dose. The mean steady-state peak plasma concentration for this 8 mg
`dose of paliperidone immediate release (Cmax ss = 113 ng/mL) was more than 2-fold the exposure
`observed with the maximum recommended 234 mg dose of INVEGA SUSTENNA®
`administered in the deltoid muscle (predicted median Cmax ss = 50 ng/mL). In this same study, a
`4 mg dose of
`the
`immediate-release oral
`formulation of paliperidone,
`for which
`Cmax ss = 35 ng/mL, showed an increased placebo-subtracted QTcLD of 6.8 msec (90% CI: 3.6;
`10.1) on day 2 at 1.5 hours post-dose.
`
`In the three fixed-dose efficacy studies of oral paliperidone extended release in subjects with
`schizophrenia, electrocardiogram (ECG) measurements taken at various time points showed only
`14
`
`
`Reference ID: 4298398
`
`
`
`
`one subject in the oral paliperidone 12 mg group had a change exceeding 60 msec at one time-
`point on Day 6 (increase of 62 msec).
`
`In the four fixed-dose efficacy studies of INVEGA SUSTENNA® in subjects with schizophrenia
`and in the long-term study in subjects with schizoaffective disorder, no subject experienced a
`change in QTcLD exceeding 60 msec and no subject had a QTcLD value of > 500 msec at any
`time point. In the maintenance study in subjects with schizophrenia, no subject had a QTcLD
`change > 60 msec, and one subject had a QTcLD value of 507 msec (Bazett’s QT corrected
`interval [QTcB] value of 483 msec); this latter subject also had a heart rate of 45 beats per
`minute.
`
`5.5 Tardive Dyskinesia
`A syndrome of potentially irreversible, involuntary, dyskinetic movements may develop in
`patients treated with antipsychotic drugs. Although the prevalence of the syndrome appears to be
`highest among the elderly, especially elderly women, it is impossible to predict which patients
`will develop the syndrome. Whether antipsychotic drug products differ in their potential to cause
`tardive dyskinesia is unknown.
`
`The risk of developing tardive dyskinesia and the likelihood that it will become irreversible
`appear to increase as the duration of treatment and the total cumulative dose of antipsychotic
`drugs administered to the patient increase, but the syndrome can develop after relatively brief
`treatment periods at low doses, although this is uncommon.
`
`The syndrome may remit, partially or completely, if antipsychotic treatment is withdrawn.
`Antipsychotic treatment itself may suppress (or partially suppress) the signs and symptoms of the
`syndrome and may thus mask the underlying process. The effect of symptomatic suppression on
`the long-term course of the syndrome is unknown.
`
`Given these considerations, INVEGA SUSTENNA® should be prescribed in a manner that is
`most likely to minimize the occurrence of tardive dyskinesia. Chronic antipsychotic treatment
`should generally be reserved for patients who suffer from a chronic illness that is known to
`respond to antipsychotic drugs. In patients who do require chronic treatment, the smallest dose
`and the shortest duration of treatment producing a satisfactory clinical response should be
`sought. The need for continued treatment should be reassessed periodically.
`
`If signs and symptoms of tardive dyskinesia appear in a patient treated with INVEGA
`SUSTENNA®, drug discontinuation should be considered. However, some patients may require
`treatment with INVEGA SUSTENNA® despite the presence of the syndrome.

`5.6 Metabolic Changes
`Atypical antipsychotic drugs have been associated with metabolic changes that may increase
`cardiovascular/cerebrovascular
`risk. These metabolic changes
`include hyperglycemia,
`dyslipidemia, and body weight gain. While all of the drugs in the class have been shown to
`produce some metabolic changes, each drug has its own specific risk profile.
`
`Hyperglycemia and Diabetes Mellitus
`Hyperglycemia and diabetes mellitus, in some cases extreme and associated with ketoacidosis or
`hyperosmolar coma or death, have been reported in patients treated with all atypical
`antipsychotics. These cases were, for the most part, seen in post-marketing clinical use and
`epidemiologic studies, not in clinical trials. Hyperglycemia and diabetes have been reported in
`trial subjects treated with INVEGA SUSTENNA®. Assessment of the relationship between
`atypical antipsychotic use and glucose abnormalities is complicated by the possibility of an
`increased background risk of diabetes mellitus in patients with schizophrenia and the increasing
`incidence of diabetes mellitus in the general population. Given these confou
