Overdose
Human Experience
In adult pre-marketing clinical studies involving more
than 3350 patients and/or healthy subjects, accidental or intentional acute
overdosage of SAPHRIS was identified in 3 patients. Among these few reported
cases of overdose, the highest estimated ingestion of SAPHRIS was 400 mg.
Reported adverse reactions at the highest dosage included agitation and
confusion.
Management Of Overdosage
There is no specific antidote to SAPHRIS. The possibility
of multiple drug involvement should be considered. An electrocardiogram should
be obtained and management of overdose should concentrate on supportive
therapy, maintaining an adequate airway, oxygenation and ventilation, and
management of symptoms. Consult with a Certified Poison Control Center for
up-to-date guidance and advice on the management of overdosage
(1-800-222-1222.)
Hypotension and circulatory collapse should be treated
with appropriate measures, such as intravenous fluids and/or sympathomimetic
agents (epinephrine and dopamine should not be used, since beta stimulation may
worsen hypotension in the setting of SAPHRIS-induced alpha blockade). In case
of severe extrapyramidal symptoms, anticholinergic medication should be
administered. Close medical supervision and monitoring should continue until
the patient recovers.
Contraindications
SAPHRIS is contraindicated in patients with:
- Severe hepatic impairment (Child-Pugh C).
- A history of hypersensitivity reactions to asenapine.
Reactions have included anaphylaxis, angioedema, hypotension, tachycardia,
swollen tongue, dyspnea, wheezing and rash.
Undesirable effects
The following adverse reactions are discussed in more
detail in other sections of the labeling:
- Use in Elderly Patients with Dementia-Related Psychosis
- Neuroleptic Malignant Syndrome
- Tardive Dyskinesia
- Metabolic Changes
- Hypersensitivity Reactions
- Orthostatic Hypotension, Syncope, and other Hemodynamic
Effects
- Falls
- Leukopenia, Neutropenia, and Agranulocytosis
- QT Interval Prolongation
- Hyperprolactinemia
- Seizures
- Potential for Cognitive and Motor Impairment
- Body Temperature Regulation
- Dysphagia
The most common adverse reactions ( ≥ 5% and at least
twice the rate of placebo) reported with acute treatment in adults with
schizophrenia were akathisia, oral hypoesthesia, and somnolence. The safety
profile of SAPHRIS in the maintenance treatment of schizophrenia in adults was
similar to that seen with acute treatment.
The most common adverse reactions ( ≥ 5% and at least
twice the rate of placebo) reported with acute monotherapy treatment of manic
or mixed episodes associated with bipolar I disorder in adults were somnolence,
oral hypoesthesia dizziness, extrapyramidal symptoms (excluding akathisia) and
akathisia; and during the adjunctive therapy trial in bipolar I disorder in
adults were somnolence and oral hypoesthesia. The rates were lower at the 5mg
twice daily dose than the 10mg twice daily dose for all of these most common
adverse reactions. The safety profile of SAPHRIS in the maintenance treatment
of manic or mixed episodes associated with bipolar I disorder in adults was
similar to that seen with acute treatment.
The adult information below is derived from a clinical
trial database for SAPHRIS consisting of over 5355 patients and/or healthy
subjects exposed to one or more sublingual doses of SAPHRIS. A total of 1427
SAPHRIS-treated patients were treated for at least 24 weeks and 785
SAPHRIS-treated patients had at least 52 weeks of exposure at therapeutic
doses.
In a 3-week monotherapy trial, the most common adverse
reactions ( ≥ 5% and at least twice the rate of placebo) reported in
pediatric patients with bipolar I disorder treated with SAPHRIS were
somnolence, dizziness, dysgeusia, oral hypoesthesia, nausea, increased
appetite, fatigue, and increased weight. No new major safety findings were
reported from a 50-week, open-label, uncontrolled safety trial.
A total of 651 pediatric patients were treated with
SAPHRIS. Of these patients, 352 pediatric patients were treated with SAPHRIS
for at least 180 days and 58 pediatric patients treated with SAPHRIS had at
least 1 year of exposure. The safety of SAPHRIS was evaluated in 403 pediatric
patients with bipolar I disorder who participated in a 3-week, placebo-controlled,
double-blind trial, of whom 302 patients received SAPHRIS at fixed doses
ranging from 2.5 mg to 10 mg twice daily.
The stated frequencies of adverse reactions represent the
proportion of individuals who experienced a treatment-emergent adverse event of
the type listed. A reaction was considered treatment emergent if it occurred
for the first time or worsened while receiving therapy following baseline
evaluation.
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 practice.
Adult Patients with Schizophrenia: The following
findings are based on the short-term placebo-controlled pre-marketing trials
for schizophrenia (a pool of three 6-week fixed-dose trials and one 6-week
flexible-dose trial) in which sublingual SAPHRIS was administered in doses
ranging from 5 to 10 mg twice daily.
Adverse Reactions Associated with Discontinuation of
Treatment: A total of 9% of SAPHRIS-treated patients and 10% of
placebo-treated patients discontinued due to adverse reactions. There were no
drug-related adverse reactions associated with discontinuation in patients
treated with SAPHRIS at the rate of at least 1% and at least twice the placebo
rate.
Adverse Reactions Occurring at an Incidence of 2% or
More in SAPHRIS-Treated Patients with Schizophrenia: Adverse reactions
associated with the use of SAPHRIS (incidence of 2% or greater, rounded to the
nearest percent, and SAPHRIS incidence greater than placebo) that occurred
during acute therapy (up to 6-weeks in patients with schizophrenia) are shown
in Table 8.

Monotherapy In Adult Patients With
Bipolar Mania
The following findings are
based on the short-term placebo-controlled trials for bipolar mania (a pool of
two 3-week flexible-dose trials and one 3-week fixed-dose trial) in which
sublingual SAPHRIS was administered in doses of 5 mg or 10 mg twice daily.
Adverse Reactions Associated
with Discontinuation of Treatment: Approximately 10% (61/620) of SAPHRIS-treated patients in
short-term, placebo-controlled trials discontinued treatment due to an adverse
reaction, compared with about 7% (22/329) on placebo. There were no adverse
reactions associated with discontinuation in patients treated with SAPHRIS at
the rate of at least 1% and at least twice the placebo rate
Adverse Reactions Occurring
at an Incidence of 2% or More Among SAPHRIS-Treated (Monotherapy) patients with
Bipolar I Disorder: Adverse reactions
associated with the use of SAPHRIS (incidence of 2% or greater, rounded to the
nearest percent, and SAPHRIS incidence greater than placebo) that occurred
during acute monotherapy (up to 3-weeks in patients with bipolar mania) are
shown in Table 9.

Monotherapy In Pediatric Patients With Bipolar Mania
The following findings are based on a 3-week ,
placebo-controlled trial for bipolar mania in which SAPHRIS was administered at
doses of 2.5 mg, 5 mg, or 10 mg twice daily.
Adverse Reactions Leading to Discontinuation of
Treatment: A total of 6.7% (7/104) of patients treated with SAPHRIS 2.5 mg
twice daily, 5.1% (5/99) of patients treated with SAPHRIS 5 mg twice daily, and
5.1% (5/99) of patients treated with SAPHRIS 10 mg twice daily discontinued
treatment due to adverse reactions compared to 4% (4/101) on placebo. The most
common adverse reactions that led to discontinuation in pediatric patients
treated with SAPHRIS (rates at least 2% in any SAPHRIS arm and at least twice the
placebo rate) were somnolence (3% in the 2.5mg twice daily group, 1% in the 5mg
twice daily group, and 2% in the 10mg twice daily group), abdominal pain (2% in
the 10mg twice daily group), and nausea (2% in the 10mg twice daily group) No
placebo-treated patients dropped out for these events.
Adverse Reactions Occurring
with SAPHRIS at an Incidence of 2% or More in SAPHRIS-treated Bipolar I
Patients: Adverse
reactions associated with the use of SAPHRIS (incidence of ≥ 2% in any
SAPHRIS dose group and greater than placebo) that occurred during acute therapy
are shown in Table 10.

(see Table 10).
Adjunctive Therapy In Adult
Patients With Bipolar Mania
The following findings are
based on a 12 week placebo-controlled trial (with a 3 week efficacy endpoint)
in adult patients with bipolar mania in which sublingual SAPHRIS was
administered in doses of 5 mg or 10 mg twice daily as adjunctive therapy with
lithium or valproate.
Adverse Reactions Associated
with Discontinuation of Treatment: Approximately 16% (25/158) of SAPHRIS-treated patients
discontinued treatment due to an adverse reaction, compared with about 11%
(18/166) on placebo. The most common adverse reactions associated with
discontinuation in subjects treated with SAPHRIS (rates at least 1% and at
least twice the placebo rate) were depression (2.5%), suicidal ideation (2.5%),
bipolar I disorder (1.9%), insomnia (1.9%) and depressive symptoms (1.3%).
Adverse Reactions Occurring
at an Incidence of 2% or More Among SAPHRIS-Treated (Adjunctive) Bipolar I
Patients: Adverse
reactions associated with the use of SAPHRIS (incidence of 2% or greater,
rounded to the nearest percent, and SAPHRIS incidence greater than placebo)
that occurred during acute adjunctive therapy at 3 weeks, a time when most of
the patients were still participating in the trial, are shown in Table 11.

† Extrapyramidal symptoms included: dystonia, parkinsonism, oculogyration, and
tremor (excluding akathisia).
‡ Somnolence includes the following events: somnolence and sedation. |
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.
Extrapyramidal Symptoms
In the short-term,
placebo-controlled schizophrenia and bipolar mania adult trials, data was
objectively collected on the Simpson Angus Rating Scale for extrapyramidal
symptoms (EPS), the Barnes Akathisia Scale (for akathisia) and the Assessments
of Involuntary Movement Scales (for dyskinesias). The mean change from baseline
for the all-SAPHRIS 5 mg or 10 mg twice daily treated group was comparable to
placebo in each of the rating scale scores.
In the short-term,
placebo-controlled schizophrenia adult trials, the incidence of reported
EPS-related events, excluding events related to akathisia, for SAPHRIS-treated
patients was 10% versus 7% for placebo; and the incidence of akathisia-related
events for SAPHRIS-treated patients was 6% versus 3% for placebo. In short-term
placebo-controlled bipolar mania adult trials, the incidence of EPS-related
events, excluding events related to akathisia, for SAPHRIS-treated patients was
8% versus 4% for placebo; and the incidence of akathisia-related events for
SAPHRIS-treated patients was 7% versus 3% for placebo. The incidence rates of
all EPS events (including akathisia) were lower at the 5mg twice daily dose
(11% of N=122) than the 10mg twice daily dose (25% of N=119) in a fixed-dose
study.
In a 3-week, placebo-controlled
pediatric trial with bipolar I disorder, the incidences of EPS-related events,
excluding events related to akathisia, were 4%, 3%, and 5% for patients treated
with SAPHRIS 2.5 mg, 5 mg, and 10 mg twice daily, respectively, as compared to
3% for placebo-treated patients. EPS-related events include: bradykinesia,
dyskinesia, dystonia, oromandibular dystonia, muscle contractions involuntary,
muscle twitching, musculoskeletal stiffness, parkinsonism, protrusion tongue,
resting tremor, and tremor.
For events of akathisia,
incidences were 2%, 2%, and 1% for pediatric patients treated with SAPHRIS 2.5
mg, 5 mg, and 10 mg twice daily, respectively, as compared to 0% for placebo-treated
patients.
Other Findings
Oral hypoesthesia and/or oral
paresthesia may occur directly after administration of SAPHRIS and usually
resolves within 1 hour.
Laboratory Test Abnormalities
Transaminases: Transient elevations in
serum transaminases (primarily ALT) in the short-term schizophrenia and bipolar
mania adult trials were more common in treated patients. In short-term,
placebo-controlled schizophrenia adult trials, the mean increase in
transaminase levels for SAPHRIS-treated patients was 1.6 units/L compared to a
decrease of 0.4 units/L for placebo-treated patients. The proportion of
patients with transaminase elevations ≥ 3 times ULN (at Endpoint) was 0.9%
for SAPHRIS-treated patients versus 1.3% for placebo-treated patients. In
short-term, placebo-controlled bipolar mania adult trials, the mean increase in
transaminase levels for SAPHRIS-treated patients was 6.1units/L compared to a
decrease of 3.9units/L in placebo-treated patients. The proportion of patients
with transaminase elevations ≥ 3 times upper limit of normal (ULN) (at
Endpoint) was 2.1% for SAPHRIS-treated patients versus 0.7% for placebo-treated
patients. The incidence rate of transaminase elevations ≥ 3 times ULN is
3% of N=95 for 10mg twice daily dose, and 0% of N=108 for the 5mg twice daily
dose and 0% of N=115 for placebo in a fixed-dose study.
In a 52-week, double-blind,
comparator-controlled trial that included primarily adult patients with
schizophrenia, the mean increase from baseline of ALT was 1.7 units/L.
In a 3-week, placebo-controlled
pediatric trial with bipolar I disorder, transient elevations in serum
transaminases (primarily ALT) were more common in treated patients. The
proportion of pediatric patients with ALT elevations ≥ 3 times upper limit
of normal (ULN) was 2.4% for patients treated with SAPHRIS 10 mg twice daily
versus none for the other SAPHRIS dose groups and placebo-treated patients.
Prolactin: In short-term,
placebo-controlled adult schizophrenia trials, the mean decreases in prolactin
levels were 6.5 ng/mL for SAPHRIS-treated patients compared to 10.7 ng/mL for
placebo-treated patients. The proportion of patients with prolactin elevations
≥ 4 times ULN (at Endpoint) were 2.6% for SAPHRIS-treated patients versus
0.6% for placebo-treated patients. In short-term, placebo-controlled bipolar
mania adult trials, the mean increase in prolactin levels was 6.7ng/mL for
SAPHRIS-treated patients compared to a decrease of 1.0 ng/mL for
placebo-treated patients. The proportion of patients with prolactin elevations ≥ 4
time
Therapeutic indications
SAPHRIS is indicated for:
- Schizophrenia in adults
- Bipolar I disorder
- Acute monotherapy of manic or mixed episodes, in adults
and pediatric patients 10 to 17 years of age
- Adjunctive treatment to lithium or valproate in adults
- Maintenance monotherapy treatment in adults
Pharmacodynamic properties
Asenapine exhibits high
affinity for serotonin 5-HT1A, 5-HT1B, 5-HT2A, 5-HT2B, 5-HT2C, 5-HT5A, 5-HT6, and
5-HT7 receptors (Ki values of 2.5, 2.7, 0.07, 0.18, 0.03, 1.6, 0.25, and 0.11
nM, respectively), dopamine D2A, D2B, D3, D4, and D1 receptors (Ki values of
1.3, 1.4, 0.42, 1.1, and 1.4 nM, respectively), α1A, α2A, α2B,
and α2C -adrenergic receptors (Ki values of 1.2, 1.2, 0.33 and 1.2 nM,
respectively), and histamine H1 receptors (Ki value 1.0 nM), and moderate
affinity for H2 receptors (Ki value of 6.2 nM). In in vitro assays asenapine
acts as an antagonist at these receptors. Asenapine has no appreciable affinity
for muscarinic cholinergic receptors (e.g., Ki value of 8128 nM for M1).
Pharmacokinetic properties
The effects of asenapine on the
pharmacokinetics of other co-administered drugs are summarized in Figure 2.
Coadministration of paroxetine with SAPHRIS caused a two-fold increase in the

enhances the inhibitory effects of paroxetine on its own metabolism by CYP2D6.

Studies In Special Populations
Exposures of asenapine in
special populations are summarized in Figure 3. Additionally, based on
population pharmacokinetic analysis, no effects of sex, race, BMI, and smoking
status on asenapine exposure were observed. Exposure in elderly patients is 30-40%
higher as compared to adults.

Clinical Studies
Efficacy of SAPHRIS was
established in the following trials:
- Two fixed-dose, short-term trials and one flexible-dose,
maintenance trial in adult patients with schizophrenia as monotherapy
- One fixed-dose and two flexible-dose, short-term trials
of monotherapy in adults with manic or mixed episodes associated with bipolar I
disorder
- One flexible-dose, maintenance trial of monotherapy in
adults with bipolar I disorder
- One fixed-dose, short term trial of monotherapy in
children (10 to 17 years) with manic or mixed episodes associated with bipolar
I disorder
- One flexible-dose, short-term trial in adult patients
with manic or mixed episode associated with bipolar I disorder as adjunctive
treatment to lithium or valproate
Schizophrenia
The efficacy of SAPHRIS in the
treatment of schizophrenia in adults was evaluated in three fixed-dose,
short-term (6 week), randomized, double-blind, placebo-controlled, and
active-controlled (haloperidol, risperidone, and olanzapine) trials of adult
patients who met DSM-IV criteria for schizophrenia and were having an acute
exacerbation of their schizophrenic illness. In two of the three trials SAPHRIS
demonstrated superior efficacy to placebo. In a third trial, SAPHRIS could not
be distinguished from placebo; however, an active control in that trial was
superior to placebo.
In the two positive trials for
SAPHRIS, the primary efficacy rating scale was the Positive and Negative
Syndrome Scale (PANSS). The PANSS is a 30 item scale that measures positive
symptoms of schizophrenia (7 items), negative symptoms of schizophrenia (7
items), and general psychopathology (16 items), each rated on a scale of 1
(absent) to 7 (extreme); total PANSS scores range from 30 to 210. The primary
endpoint was change from baseline to endpoint on the PANSS total score. The
results of the SAPHRIS trials in schizophrenia follow:
In trial 1, a 6-week trial
(n=174), comparing SAPHRIS (5 mg twice daily) to placebo, SAPHRIS 5 mg twice
daily was statistically superior to placebo on the PANSS total score (Trial 1
in Table 13).
In trial 2, a 6-week trial
(n=448), comparing two fixed doses of SAPHRIS (5 mg and 10 mg twice daily) to
placebo, SAPHRIS 5 mg twice daily was statistically superior to placebo on the
PANSS total score. SAPHRIS 10 mg twice daily showed no added benefit compared
to 5 mg twice daily and was not significantly different from placebo (Trial 2
in Table 13).
An examination of population
subgroups did not reveal any clear evidence of differential responsiveness on
the basis of age, sex or race.

Maintenance of efficacy has been demonstrated in a
placebo-controlled, double-blind, multicenter, flexible dose (5 mg or 10 mg
twice daily based on tolerability) clinical trial with a randomized withdrawal
design. All patients were initially administered 5 mg
twice daily for 1 week and then titrated up to 10 mg twice daily. A total of
700 patients entered open-label treatment with SAPHRIS for a period of 26
weeks. Of these, a total of 386 patients who met pre-specified criteria for
continued stability (mean length of stabilization was 22 weeks) were randomized
to a double-blind, placebo-controlled, randomized withdrawal phase. SAPHRIS was
statistically superior to placebo in time to relapse or impending relapse
defined as increase in PANSS ≥ 20% from baseline and a Clinical Global
Impression-Severity of Illness (CGI-S) score ≥ 4 (at least 2 days within 1
week) or PANSS score ≥ 5 on “hostility” or “uncooperativeness” items and
CGI-S score ≥ 4 ( ≥ 2 days within a week), or PANSS score ≥ 5 on
any two of the following items: “unusual thought content,” “conceptual
disorganization,” or “hallucinatory behavior” items, and CGI-S score ≥ 4
( ≥ 2 days within 1 week) or investigator judgment of worsening symptoms or
increased risk of violence to self (including suicide) or other persons. The
Kaplan-Meier curves of the time to relapse or impending relapse during the
double-blind, placebo-controlled, randomized withdrawal phase of this trial for
SAPHRIS and placebo are shown in Figure 4.

Bipolar I Disorder
Monotherapy
Adults: The efficacy of SAPHRIS
in the treatment of acute mania was established in two similarly designed
3-week, randomized, double-blind, placebo-controlled, and active-controlled
(olanzapine) trials of adult patients who met DSM-IV criteria for Bipolar I
Disorder with an acute manic or mixed episode with or without psychotic
features.
The primary rating instrument
used for assessing manic symptoms in these trials was the Young Mania Rating
Scale (YMRS), an 11-item clinician-rated scale traditionally used to assess the
degree of manic symptomatology in a range from 0 (no manic features) to 60
(maximum score). Patients were also assessed on the Clinical Global Impression -
Bipolar (CGI-BP) scale. In both trials, all patients randomized to SAPHRIS were
initially administered 10 mg twice daily, and the dose could be adjusted within
the dose range of 5 to 10 mg twice daily from Day 2 onward based on efficacy
and tolerability. Ninety percent of patients remained on the 10 mg twice daily
dose. SAPHRIS was statistically superior to placebo on the YMRS total score and
the CGI-BP Severity of Illness score (mania) in both studies (Trials 1 and 2 in
Table 14).
In another 3-week, randomized,
double-blind, placebo-controlled trial (n=359), comparing two fixed doses of
SAPHRIS (5 mg and 10 mg twice daily) to placebo, both doses were statistically
superior to placebo on the YMRS total score and CGI-BP Severity of Illness
overall score. (Trial 3 in Table 14).
An examination of subgroups did not reveal any clear
evidence of differential responsiveness on the basis of age, sex, or race.
Maintenance of efficacy has been demonstrated in a
placebo-controlled, double-blind, multicenter, flexible dose (5 mg or 10 mg
twice daily based on tolerability) clinical trial with a randomized withdrawal
design. All patients were initially administered 5 or 10 mg twice daily, and
the option to titrate down to 5 mg twice daily was provided based on
tolerability. A total of 549 patients entered open-label treatment with SAPHRIS
for a period of 12 to16 weeks. Of these, a total of 252 patients who met
pre-specified criteria for continued stability were randomized to and treated
in a double-blind, placebo-controlled, randomized withdrawal phase. SAPHRIS was
statistically superior to placebo in time to relapse defined as 1) YMRS or
MADRS score ≥ 16; 2) requirement or initiation of any non-study
medication to treat mixed, manic, or depressive symptoms, including an
antipsychotic, antidepressant, or mood-stabilizing agent; 3) requirement or
initiation of psychiatric hospitalization; 4) investigator judgment to
discontinue the study due to a mood event. The Kaplan-Meier curves of the time
to relapse during the double-blind, placebo-controlled, randomized withdrawal
phase of this trial for SAPHRIS and placebo are shown in Figure 5.
Figure 5: Kaplan-Meier Estimation of Percent Relapse
for SAPHRIS and Placebo
Pediatric patients: The efficacy of SAPHRIS
in the treatment of acute mania was established in a single, 3-week,
placebo-controlled, double-blind trial of 403 pediatric patients 10 to 17 years
of age, of whom 302 patients received SAPHRIS at fixed doses of 2.5 mg, 5 mg
and 10 mg twice daily. All patients were started on 2.5 mg twice daily. For
those assigned to 5 mg twice daily, the dose was increased to 5 mg twice daily
after 3 days. For those assigned to 10 mg twice daily, the dose was increased
from 2.5 to 5 mg twice daily after 3 days, and then to 10 mg twice daily after
3 additional days.
SAPHRIS was statistically
superior to placebo in improving YMRS total score and the CGI-BP Severity of
Illness overall score as measured by the change from baseline to week 3 (Trial
3 Pediatric in Table 14). An examination of subgroups did not reveal any clear
evidence of differential responsiveness on the basis of age, sex, and race.
Adjunctive Therapy
The efficacy of SAPHRIS as an adjunctive therapy in acute
mania was established in a 12week, placebo-controlled trial with a 3-week
primary efficacy endpoint involving 326 adult patients with a manic or mixed
episode of Bipolar I Disorder, with or without psychotic features, who were
partially responsive to lithium or valproate monotherapy after at least 2 weeks
of treatment. All patients randomized to SAPHRIS were initially administered 5
mg twice daily, and the dose could be adjusted within the dose range of 5 to 10
mg twice daily from Day 2 onward based on efficacy and tolerability. SAPHRIS
was statistically superior to placebo in the reduction of manic symptoms
(measured by the YMRS total score) as an adjunctive therapy to lithium or
valproate monotherapy at Week 3 (Trial 5 Adjunctive in Table 14).

Pregnancy Exposure Registry
There is a pregnancy exposure
registry that monitors pregnancy outcomes in women exposed to SAPHRIS during
pregnancy. For more information contact the National Pregnancy Registry for
Atypical Antipsychotics at 1-866-9612388 or visit http://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/.
Risk Summary
Neonates exposed to
antipsychotic drugs during the third trimester of pregnancy are at risk for
extrapyramidal and/or withdrawal symptoms. Studies have not been conducted with
SAPHRIS in pregnant women. There are no available human data informing the
drug-associated risk. The background risk of major birth defects and
miscarriage for the indicated populations are unknown. However, the background
risk in the U.S. general population of major birth defects is 2-4% and of
miscarriage is 15-20% of clinically recognized pregnancies. No teratogenicity
was observed in animal reproduction studies with intravenous administration of
asenapine to rats and rabbits during organogenesis at doses 0.7 and 0.4 times,
respectively, the maximum recommended human dose (MRHD) of 10 mg sublingually
twice daily. In a pre-and post-natal study in rats, intravenous administration
of asenapine at doses up to 0.7 times the MRHD produced increases in
post-implantation loss and early pup deaths, and decreases in subsequent pup
survival and weight gain. Advise pregnant women of the
potential risk to a fetus.
Clinical Considerations
Fetal/Neonatal Adverse Reactions
Extrapyramidal and/or withdrawal symptoms, including
agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress and
feeding disorder have been reported in neonates who were exposed to
antipsychotic drugs during the third trimester of pregnancy. These symptoms
have varied in severity. Some neonates recovered within hours or days without
specific treatment; others required prolonged hospitalization. Monitor neonates
for extrapyramidal and/or withdrawal symptoms and manage symptoms
appropriately.
Data
Animal Data
In animal studies, asenapine increased post-implantation
loss and decreased pup weight and survival at doses similar to or less than
recommended clinical doses. In these studies there was no increase in the
incidence of structural abnormalities caused by asenapine.
Asenapine was not teratogenic in reproduction studies in
rats and rabbits at intravenous doses up to 1.5 mg/kg in rats and 0.44 mg/kg in
rabbits administered during organogenesis. These doses are 0.7 and 0.4 times,
respectively, the maximum recommended human dose (MRHD) of 10 mg twice daily
given sublingually on a mg/m² basis. Plasma levels of asenapine were
measured in the rabbit study, and the area under the curve (AUC) at the highest
dose tested was 2 times that in humans receiving the MRHD.
In a study in which rats were treated from day 6 of
gestation through day 21 postpartum with intravenous doses of asenapine of 0.3,
0.9, and 1.5 mg/kg/day (0.15, 0.4, and 0.7 times the MRHD of 10 mg twice daily
given sublingually on a mg/m² basis), increases in post-implantation
loss and early pup deaths were seen at all doses, and decreases in subsequent
pup survival and weight gain were seen at the two higher doses. A
cross-fostering study indicated that the decreases in pup survival were largely
due to prenatal drug effects. Increases in post-implantation loss and decreases
in pup weight and survival were also seen when pregnant rats were dosed orally
with asenapine.

PRECAUTIONS
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), largely in patients
taking atypical antipsychotic drugs, revealed a risk of death in the
drug-treated patients of between 1.6 to 1.7 times that seen 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. SAPHRIS is not approved for the treatment of patients with
dementia-related psychosis.
Cerebrovascular Adverse Events, 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. SAPHRIS is not approved for the treatment of patients
with dementia-related psychosis.
Neuroleptic Malignant Syndrome
A potentially fatal symptom complex sometimes referred to
as Neuroleptic Malignant Syndrome (NMS) has been reported in association with
administration of antipsychotic drugs, including SAPHRIS. 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. It is important to exclude cases where the clinical
presentation includes both serious medical illness (e.g. pneumonia, systemic
infection) 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 NMS.
If a patient requires antipsychotic drug treatment after
recovery from NMS, the potential reintroduction of drug therapy should be
carefully considered. The patient should be carefully monitored, since
recurrences of NMS have been reported.
Tardive Dyskinesia
A syndrome of potentially irreversible, involuntary,
dyskinetic movements can 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 rely upon prevalence
estimates to predict, at the inception of antipsychotic treatment, which patients
are likely to develop the syndrome. Whether antipsychotic drug products differ
in their potential to cause Tardive Dyskinesia (TD) is unknown.
The risk of developing TD and the likelihood that it will
become irreversible are believed to increase as the duration of treatment and
the total cumulative dose of antipsychotic drugs administered to the patient
increase. However, the syndrome can develop, although much less commonly, after
relatively brief treatment periods at low doses.
There is no known treatment for established cases of TD,
although the syndrome may remit, partially or completely, if antipsychotic
treatment is withdrawn. Antipsychotic treatment, itself, however, may suppress
(or partially suppress) the signs and symptoms of the syndrome and thereby may
possibly mask the underlying process. The effect that symptomatic suppression
has upon the long-term course of the syndrome is unknown.
Given these considerations, SAPHRIS should be prescribed
in a manner that is most likely to minimize the occurrence of TD. Chronic
antipsychotic treatment should generally be reserved for patients who suffer
from a chronic illness that (1) is known to respond to antipsychotic drugs, and
(2) for whom alternative, equally effective, but potentially less harmful
treatments are not available or appropriate. 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 TD appear in a patient on
SAPHRIS, drug discontinuation should be considered. However, some patients may
require treatment with SAPHRIS despite the presence of the syndrome.
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. W
hile 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, in some cases extreme and associated with
ketoacidosis or hyperosmolar coma or death, has been reported in patients
treated with atypical antipsychotics. 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 confounders, the relationship between atypical
antipsychotic use and hyperglycemia-related adverse reactions is not completely
understood. However, epidemiological studies suggest an increased risk of
treatment-emergent hyperglycemia-related adverse events in patients treated
with the atypical antipsychotics included in these studies. Precise risk
estimates for hyperglycemia-related adverse events in patients treated with
atypical antipsychotics are not available.
Patients with an established diagnosis of diabetes
mellitus who are started on atypical antipsychotics should be monitored
regularly for worsening of glucose control. Patients with risk factors for
diabetes mellitus (e.g., obesity, family history of diabetes) who are starting
treatment with atypical antipsychotics should undergo fasting blood glucose
testing at the beginning of treatment and periodically during treatment. Any
patient treated with atypical antipsychotics should be monitored for symptoms
of hyperglycemia including polydipsia, polyuria, polyphagia, and weakness.
Patients who develop symptoms of hyperglycemia during treatment with atypical
antipsychotics should undergo fasting blood glucose testing. In some cases,
hyperglycemia has resolved when the atypical antipsychotic was discontinued;
however, some patients required continuation of anti-diabetic treatment despite
discontinuation of the antipsychotic drug.

In short-term schizophrenia
trials, the proportion of patients with total cholesterol elevations ≥ 240
mg/dL (at Endpoint) was 8.3% for SAPHRIS-treated patients versus 7% for
placebo-treated patients. The proportion of patients with elevations in
triglycerides ≥ 200 mg/dL (at Endpoint) was 13.2% for SAPHRIS-treated
patients versus 10.5% for placebo-treated patients. In short-term,
placebo-controlled bipolar mania trials, the proportion of patients with total
cholesterol elevations ≥ 240 mg/dL (at Endpoint) was 8.7% for
SAPHRIS-treated patients versus 8.6% for placebo-treated patients. The
proportion of patients with elevations in triglycerides ≥ 200 mg/dL (at
Endpoint) was 15.2% for SAPHRIS-treated patients versus 11.4% for
placebo-treated patients.
In a 52-week, double-blind,
comparator-controlled trial that included primarily patients with
schizophrenia, the mean decrease from baseline of total cholesterol was 6 mg/dL
and the mean decrease from baseline of fasting triglycerides was 9.8 mg/dL.
Pediatric Patients: Data from the short-term,
placebo-controlled bipolar mania trial are presented in Table 4.

Weight Gain
Increases in weight have been
observed in pre-marketing clinical trials with SAPHRIS. Patients receiving
SAPHRIS should receive regular monitoring of weight.
Adult Patients: Pooled data on mean
changes in body weight and the proportion of subjects meeting a weight gain
criterion of ≥ 7% of body weight from the short-term, placebo-controlled
schizophrenia and bipolar mania trials are presented in Table 5.

Pediatric Patients: Data on mean changes in
body weight and the proportion of pediatric patients meeting a weight gain
criterion of ≥ 7% of body weight from the short-term, placebo-controlled
bipolar mania trial are presented in Table 7. To adjust for normal growth,
z-scores were derived (measured in standard deviations [SD]), which normalize
for the natural growth of pediatric patients by comparisons to age-and
sex-matched population standards.
The distance of a z-score from
0 represents the distance of a percentile from the median, measured in standard
deviations (SD). After adjusting for age and sex, the mean change from baseline
to endpoint in weight z-score for SAPHRS 2.5 mg, 5 mg, and 10 mg twice daily,
was 0.11, 0.08 and 0.09 SD versus 0.02 SD for placebo, respectively.
When treating pediatric
patients, weight gain should be monitored and assessed against that expected
for normal growth.

Hypersensitivity Reactions
Hypersensitivity reactions have
been observed in patients treated with SAPHRIS. In several cases, these
reactions occurred after the first dose. These hypersensitivity reactions
included: anaphylaxis, angioedema, hypotension, tachycardia, swollen tongue,
dyspnea, wheezing and rash.
Orthostatic Hypotension,
Syncope, And Other Hemodynamic Effects
SAPHRIS may induce orthostatic
hypotension and syncope in some patients, especially early in treatment,
because of its α1-adrenergic antagonist activity. In short-term
schizophrenia adult trials, syncope was reported in 0.2% (1/572) of patients
treated with therapeutic doses (5 mg or 10 mg twice daily) of SAPHRIS, compared
to 0.3% (1/378) of patients treated with placebo. In short-term bipolar mania
adult trials, syncope was reported in 0.3% (1/379) of patients treated with
therapeutic doses (5 mg or 10 mg twice daily) of SAPHRIS, compared to 0%
(0/203) of patients treated with placebo. During adult pre-marketing clinical
trials with SAPHRIS, including long-term trials without comparison to placebo,
syncope was reported in 0.6% (11/1953) of patients treated with SAPHRIS. In a
3-week, bipolar mania pediatric trial, syncope was reported in 1% (1/104) of
patients treated with SAPHRIS 2.5 mg twice daily, 1% (1/99) of patients treated
with SAPHRIS 5 mg twice daily, and 0% (0/99) for patients treated with SAPHRIS
10 mg twice daily compared to 0% (0/101) for patients treated with placebo.
Patients should be instructed
about non-pharmacologic interventions that help to reduce the occurrence of
orthostatic hypotension (e.g., sitting on the edge of the bed for several
minutes before attempting to stand in the morning and slowly rising from a
seated position). SAPHRIS should be used with caution in (1) patients with
known cardiovascular disease (history of myocardial infarction or ischemic
heart disease, heart failure or conduction abnormalities), cerebrovascular
disease, or conditions which would predispose patients to hypotension
(dehydration, hypovolemia, and treatment with antihypertensive medications);
and (2) in the elderly. SAPHRIS should be used cautiously when treating
patients who receive treatment with other drugs that can induce hypotension,
bradycardia, respiratory or central nervous system depression. Monitoring of orthostatic vital signs should be considered
in all such patients, and a dose reduction should be considered if hypotension
occurs.
Leukopenia, Neutropenia, And Agranulocytosis
In clinical trial and
postmarketing experience, leukopenia and neutropenia have been reported
temporally related to antipsychotic agents, including SAPHRIS. Agranulocytosis
(including fatal cases) has been reported with other agents in the class.
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 pre-existing low W BC/ANC or
drug-induced leukopenia/neutropenia, perform a complete blood count (CBC)
frequently during the first few months of therapy. In such patients, consider
discontinuation of SAPHRIS at the first sign of a clinically significant
decline in W BC in the absence of other causative factors.
Monitor patients with
clinically significant neutropenia for fever or other symptoms or signs of
infection and treat promptly if such symptoms or signs occur. Discontinue
SAPHRIS in patients with severe neutropenia (absolute neutrophil count
< 1000/mm³) and follow their W BC until recovery.
QT Prolongation
The effects of SAPHRIS on the
QT/QTc interval were evaluated in a dedicated adult QT study. This trial
involved SAPHRIS doses of 5 mg, 10 mg, 15 mg, and 20 mg twice daily, and
placebo, and was conducted in 151 clinically stable patients with
schizophrenia, with electrocardiographic assessments throughout the dosing
interval at baseline and steady state. At these doses, SAPHRIS was associated
with increases in QTc interval ranging from 2 to 5 msec compared to placebo. No
patients treated with SAPHRIS experienced QTc increases ≥ 60 msec from
baseline measurements, nor did any patient experience a QTc of ≥ 500 msec.
Electrocardiogram (ECG)
measurements were taken at various time points during the SAPHRIS clinical
trial program (5 mg or 10 mg twice daily doses). Post-baseline QT prolongations
exceeding 500 msec were reported at comparable rates for SAPHRIS and placebo in
these short-term trials. There were no reports of Torsade de Pointes or any
other adverse reactions associated with delayed ventricular repolarization.
The use of SAPHRIS should be
avoided in combination with other drugs known to prolong QTc including Class 1A
antiarrhythmics (e.g., quinidine, procainamide) or Class 3 antiarrhythmics
(e.g., amiodarone, sotalol), antipsychotic medications (e.g., ziprasidone,
chlorpromazine, thioridazine), and antibiotics (e.g., gatifloxacin,
moxifloxacin). SAPHRIS should also be avoided in patients with a history of
cardiac arrhythmias and in other circumstances that may increase the risk of
the occurrence of torsade de pointes and/or sudden death in association with
the use of drugs that prolong the QTc interval, including bradycardia;
hypokalemia or hypomagnesemia; and presence of congenital prolongation of the
QT interval.
Hyperprolactinemia
Like other drugs that
antagonize dopamine D2 receptors, SAPHRIS can elevate prolactin levels, and the
elevation can persist during chronic administration. Hyperprolactinemia may
suppress hypothalamic GnRH, resulting in reduced pituitary gonadotropin
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. In SAPHRIS adult clinical trials, the incidences of adverse events
related to abnormal prolactin levels were 0.4% versus 0% for placebo. In a
3-week, bipolar mania pediatric trial, the incidence of adverse events related
to abnormal prolactin levels were 0% in the SAPHRIS 2.5 mg twice daily
treatment group, 2% in the SAPHRIS 5 mg twice daily treatment group, and 1% in
the SAPHRIS 10 mg twice daily treatment group versus to 1% for patients treated
with placebo.
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. 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.
Seizures
Seizures were reported in 0% and 0.3% (0/572, 1/379) of
adult patients treated with doses of 5 mg and 10 mg twice daily of SAPHRIS,
respectively, compared to 0% (0/503, 0/203) of patients treated with placebo in
short-term schizophrenia and bipolar mania trials, respectively. During adult
pre-marketing clinical trials with SAPHRIS, including long-term trials without
comparison to placebo, seizures were reported in 0.3% (5/1953) of patients
treated with SAPHRIS. There were no reports of seizures in pediatric patients
treated with SAPHRIS in a 3-week-term, bipolar mania trial.
As with other antipsychotic drugs, SAPHRIS should be used
with caution in patients with a history of seizures or with conditions that
potentially lower the seizure threshold. Conditions that lower the seizure
threshold may be more prevalent in patients 65 years or older.
Potential For Cognitive And Motor Impairment
Somnolence was reported in patients treated with SAPHRIS.
It was usually transient with the highest incidence reported during the first
week of treatment. In short-term, fixed-dose, placebo-controlled schizophrenia
adult trials, somnolence was reported in 15% (41/274) of patients on SAPHRIS 5
mg twice daily and in 13% (26/208) of patients on SAPHRIS 10 mg twice daily
compared to 7% (26/378) of placebo patients. In short-term, placebo-controlled
bipolar mania adult trials of therapeutic doses (5-10 mg twice daily),
somnolence was reported in 24% (90/379) of patients on SAPHRIS compared to 6%
(13/203) of placebo patients. During adult pre-marketing clinical trials with
SAPHRIS, including long-term trials without comparison to placebo, somnolence
was reported in 18% (358/1953) of patients treated with SAPHRIS. Somnolence
(including sedation) led to discontinuation in 0.6% (12/1953) of patients in
short-term, placebo-controlled trials.
In a 3-week, placebo-controlled, bipolar I pediatric
trial, the incidence of somnolence (including sedation and hypersomnia) for
placebo, SAPHRIS 2.5 mg twice daily, 5 mg twice daily, and 10 mg twice daily,
was 12% (12/101), 46% (48/104), 53% (52/99), and 49% (49/99), respectively.
Somnolence led to discontinuation in 0%, 3%, 1%, and 2% of patients treated
with placebo, and SAPHRIS 2.5 mg twice daily, 5 mg twice daily, and 10 mg twice
daily, respectively.
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 SAPHRIS therapy does
not affect them adversely.
Body Temperature Regulation
Disruption of the body's ability to reduce core body
temperature has been attributed to antipsychotic agents. In the short-term
placebo-controlled trials for both schizophrenia and acute bipolar disorder,
the incidence of adverse reactions suggestive of
Dosage (Posology) and method of administration
Administration Instructions
SAPHRIS is a sublingual tablet. To ensure optimal
absorption, patients should be instructed to place the tablet under the tongue
and allow it to dissolve completely. The tablet will dissolve in saliva within
seconds. SAPHRIS sublingual tablets should not be split, crushed, chewed, or
swallowed. Patients should be instructed to
not eat or drink for 10 minutes after administration.
Schizophrenia
The recommended dose of SAPHRIS is 5 mg given twice
daily. In short-term controlled trials, there was no suggestion of added
benefit with a 10 mg twice daily dose, but there was a clear increase in
certain adverse reactions. If tolerated, daily dosage can be increased to 10 mg
twice daily after one week. The safety of doses above 10 mg twice daily has not
been evaluated in clinical studies.
Bipolar I Disorder
Acute Treatment Of Manic Or Mixed Episodes
Monotherapy in Adults: The recommended starting
and treatment dose of SAPHRIS is 5 mg to 10 mg twice daily. The safety of doses
above 10 mg twice daily has not been evaluated in clinical trials.
Monotherapy in Pediatric Patients: The recommended
dose of SAPHRIS is 2.5 mg to 10 mg twice daily in pediatric patients 10 to 17
years of age, and dose may be adjusted for individual response and
tolerability. The starting dose of SAPHRIS is 2.5 mg twice daily. After 3 days,
the dose can be increased to 5 mg twice daily, and from 5 mg to 10 mg twice
daily after 3 additional days. Pediatric patients aged 10 to 17 years appear to
be more sensitive to dystonia with initial dosing with SAPHRIS when the recommended
escalation schedule is not followed.
The safety of doses greater than 10 mg twice daily has not been evaluated in
clinical trials.
Adjunctive Therapy in Adults: The recommended
starting dose of SAPHRIS is 5 mg twice daily when administered as adjunctive
therapy with either lithium or valproate. Depending on the clinical response
and tolerability in the individual patient, the dose can be increased to 10 mg
twice daily. The safety of doses above 10 mg twice daily as adjunctive therapy
with lithium or valproate has not been evaluated in clinical trials.
For patients on SAPHRIS, whether used as monotherapy or
as adjunctive therapy with lithium or valproate, it is generally recommended
that responding patients continue treatment beyond the acute episode.
Maintenance Treatment Of Bipolar I Disorder
Monotherapy in Adults: Continue on the SAPHRIS
dose that the patient received during stabilization (5 mg to 10 mg twice
daily). Depending on the clinical response and tolerability in the individual
patient, a dose of 10 mg twice daily can be decreased to 5 mg twice daily. The
safety of doses above 10 mg twice daily has not been evaluated in clinical
trials.

- Body Temperature Regulation
- Dysphagia
The most common adverse reactions ( ≥ 5% and at least
twice the rate of placebo) reported with acute treatment in adults with
schizophrenia were akathisia, oral hypoesthesia, and somnolence. The safety
profile of SAPHRIS in the maintenance treatment of schizophrenia in adults was
similar to that seen with acute treatment.
The most common adverse reactions ( ≥ 5% and at least
twice the rate of placebo) reported with acute monotherapy treatment of manic
or mixed episodes associated with bipolar I disorder in adults were somnolence,
oral hypoesthesia dizziness, extrapyramidal symptoms (excluding akathisia) and
akathisia; and during the adjunctive therapy trial in bipolar I disorder in
adults were somnolence and oral hypoesthesia. The rates were lower at the 5mg
twice daily dose than the 10mg twice daily dose for all of these most common
adverse reactions. The safety profile of SAPHRIS in the maintenance treatment
of manic or mixed episodes associated with bipolar I disorder in adults was
similar to that seen with acute treatment.
The adult information below is derived from a clinical
trial database for SAPHRIS consisting of over 5355 patients and/or healthy
subjects exposed to one or more sublingual doses of SAPHRIS. A total of 1427
SAPHRIS-treated patients were treated for at least 24 weeks and 785
SAPHRIS-treated patients had at least 52 weeks of exposure at therapeutic
doses.
In a 3-week monotherapy trial, the most common adverse
reactions ( ≥ 5% and at least twice the rate of placebo) reported in
pediatric patients with bipolar I disorder treated with SAPHRIS were
somnolence, dizziness, dysgeusia, oral hypoesthesia, nausea, increased
appetite, fatigue, and increased weight. No new major safety findings were
reported from a 50-week, open-label, uncontrolled safety trial.
A total of 651 pediatric patients were treated with
SAPHRIS. Of these patients, 352 pediatric patients were treated with SAPHRIS
for at least 180 days and 58 pediatric patients treated with SAPHRIS had at
least 1 year of exposure. The safety of SAPHRIS was evaluated in 403 pediatric
patients with bipolar I disorder who participated in a 3-week, placebo-controlled,
double-blind trial, of whom 302 patients received SAPHRIS at fixed doses
ranging from 2.5 mg to 10 mg twice daily.
The stated frequencies of adverse reactions represent the
proportion of individuals who experienced a treatment-emergent adverse event of
the type listed. A reaction was considered treatment emergent if it occurred
for the first time or worsened while receiving therapy following baseline
evaluation.
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 practice.
Adult Patients with Schizophrenia: The following
findings are based on the short-term placebo-controlled pre-marketing trials
for schizophrenia (a pool of three 6-week fixed-dose trials and one 6-week
flexible-dose trial) in which sublingual SAPHRIS was administered in doses
ranging from 5 to 10 mg twice daily.
Adverse Reactions Associated with Discontinuation of
Treatment: A total of 9% of SAPHRIS-treated patients and 10% of
placebo-treated patients discontinued due to adverse reactions. There were no
drug-related adverse reactions associated with discontinuation in patients
treated with SAPHRIS at the rate of at least 1% and at least twice the placebo
rate.
Adverse Reactions Occurring at an Incidence of 2% or
More in SAPHRIS-Treated Patients with Schizophrenia: Adverse reactions
associated with the use of SAPHRIS (incidence of 2% or greater, rounded to the
nearest percent, and SAPHRIS incidence greater than placebo) that occurred
during acute therapy (up to 6-weeks in patients with schizophrenia) are shown
in Table 8.

Monotherapy In Adult Patients With
Bipolar Mania
The following findings are
based on the short-term placebo-controlled trials for bipolar mania (a pool of
two 3-week flexible-dose trials and one 3-week fixed-dose trial) in which
sublingual SAPHRIS was administered in doses of 5 mg or 10 mg twice daily.
Adverse Reactions Associated
with Discontinuation of Treatment: Approximately 10% (61/620) of SAPHRIS-treated patients in
short-term, placebo-controlled trials discontinued treatment due to an adverse

Monotherapy In Pediatric Patients With Bipolar Mania
The following findings are based on a 3-week ,
placebo-controlled trial for bipolar mania in which SAPHRIS was administered at
doses of 2.5 mg, 5 mg, or 10 mg twice daily.
Adverse Reactions Leading to Discontinuation of
Treatment: A total of 6.7% (7/104) of patients treated with SAPHRIS 2.5 mg
twice daily, 5.1% (5/99) of patients treated with SAPHRIS 5 mg twice daily, and
5.1% (5/99) of patients treated with SAPHRIS 10 mg twice daily discontinued
treatment due to adverse reactions compared to 4% (4/101) on placebo. The most
common adverse reactions that led to discontinuation in pediatric patients
treated with SAPHRIS (rates at least 2% in any SAPHRIS arm and at least twice the
placebo rate) were somnolence (3% in the 2.5mg twice daily group, 1% in the 5mg
twice daily group, and 2% in the 10mg twice daily group), abdominal pain (2% in
the 10mg twice daily group), and nausea (2% in the 10mg twice daily group) No
placebo-treated patients dropped out for these events.
Adverse Reactions Occurring
with SAPHRIS at an Incidence of 2% or More in SAPHRIS-treated Bipolar I
Patients: Adverse
reactions associated with the use of SAPHRIS (incidence of ≥ 2% in any
SAPHRIS dose group and greater than placebo) that occurred during acute therapy
are shown in Table 10.

Dose-Related Adverse Reactions: In the short term
pediatric bipolar I trial the incidence of fatigue appeared to be dose-related
(see Table 10).
Adjunctive Therapy In Adult
Patients With Bipolar Mania
The following findings are
based on a 12 week placebo-controlled trial (with a 3 week efficacy endpoint)
in adult patients with bipolar mania in which sublingual SAPHRIS was
administered in doses of 5 mg or 10 mg twice daily as adjunctive therapy with
lithium or valproate.
Adverse Reactions Associated
with Discontinuation of Treatment: Approximately 16% (25/158) of SAPHRIS-treated patients
discontinued treatment due to an adverse reaction, compared with about 11%
(18/166) on placebo. The most common adverse reactions associated with
discontinuation in subjects treated with SAPHRIS (rates at least 1% and at
least twice the placebo rate) were depression (2.5%), suicidal ideation (2.5%),
bipolar I disorder (1.9%), insomnia (1.9%) and depressive symptoms (1.3%).
Adverse Reactions Occurring
at an Incidence of 2% or More Among SAPHRIS-Treated (Adjunctive) Bipolar I
Patients: Adverse
reactions associated with the use of SAPHRIS (incidence of 2% or greater,
rounded to the nearest percent, and SAPHRIS incidence greater than placebo)
that occurred during acute adjunctive therapy at 3 weeks, a time when most of
the patients were still participating in the trial, are shown in Table 11.

† Extrapyramidal symptoms included: dystonia, parkinsonism, oculogyration, and
tremor (excluding akathisia).
‡ Somnolence includes the following events: somnolence and sedation. |
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.
Extrapyramidal Symptoms
In the short-term,
placebo-controlled schizophrenia and bipolar mania adult trials, data was
objectively collected on the Simpson Angus Rating Scale for extrapyramidal
symptoms (EPS), the Barnes Akathisia Scale (for akathisia) and the Assessments
of Involuntary Movement Scales (for dyskinesias). The mean change from baseline
for the all-SAPHRIS 5 mg or 10 mg twice daily treated group was comparable to
placebo in each of the rating scale scores.
In the short-term,
placebo-controlled schizophrenia adult trials, the incidence of reported
EPS-related events, excluding events related to akathisia, for SAPHRIS-treated
patients was 10% versus 7% for placebo; and the incidence of akathisia-related
events for SAPHRIS-treated patients was 6% versus 3% for placebo. In short-term
placebo-controlled bipolar mania adult trials, the incidence of EPS-related
events, excluding events related to akathisia, for SAPHRIS-treated patients was
8% versus 4% for placebo; and the incidence of akathisia-related events for
SAPHRIS-treated patients was 7% versus 3% for placebo. The incidence rates of
all EPS events (including akathisia) were lower at the 5mg twice daily dose
(11% of N=122) than the 10mg twice daily dose (25% of N=119) in a fixed-dose
study.
In a 3-week, placebo-controlled
pediatric trial with bipolar I disorder, the incidences of EPS-related events,
excluding events related to akathisia, were 4%, 3%, and 5% for patients treated
with SAPHRIS 2.5 mg, 5 mg, and 10 mg twice daily, respectively, as compared to
3% for placebo-treated patients. EPS-related events include: bradykinesia,
dyskinesia, dystonia, oromandibular dystonia, muscle contractions involuntary,
muscle twitching, musculoskeletal stiffness, parkinsonism, protrusion tongue,
resting tremor, and tremor.
For events of akathisia,
incidences were 2%, 2%, and 1% for pediatric patients treated with SAPHRIS 2.5
mg, 5 mg, and 10 mg twice daily, respectively, as compared to 0% for placebo-treated
patients.
Other Findings
Oral hypoesthesia and/or oral
paresthesia may occur directly after administration of SAPHRIS and usually
resolves within 1 hour.
Laboratory Test Abnormalities
Transaminases: Transient elevations in
serum transaminases (primarily ALT) in the short-term schizophrenia and bipolar
mania adult trials were more common in treated patients. In short-term,
placebo-controlled schizophrenia adult trials, the mean increase in
transaminase levels for SAPHRIS-treated patients was 1.6 units/L compared to a
decrease of 0.4 units/L for placebo-treated patients. The proportion of
patients with transaminase elevations ≥ 3 times ULN (at Endpoint) was 0.9%
for SAPHRIS-treated patients versus 1.3% for placebo-treated patients. In
short-term, placebo-controlled bipolar mania adult trials, the mean increase in
transaminase levels for SAPHRIS-treated patients was 6.1units/L compared to a
decrease of 3.9units/L in placebo-treated patients. The proportion of patients
with transaminase elevations ≥ 3 times upper limit of normal (ULN) (at
Endpoint) was 2.1% for SAPHRIS-treated patients versus 0.7% for placebo-treated
patients. The incidence rate of transaminase elevations ≥ 3 times ULN is
3% of N=95 for 10mg twice daily dose, and 0% of N=108 for the 5mg twice daily
dose and 0% of N=115 for placebo in a fixed-dose study.
In a 52-week, double-blind,
comparator-controlled trial that included primarily adult patients with
schizophrenia, the mean increase from baseline of ALT was 1.7 units/L.
In a 3-week, placebo-controlled
pediatric trial with bipolar I disorder, transient elevations in serum
transaminases (primarily ALT) were more common in treated patients. The
proportion of pediatric patients with ALT elevations ≥ 3 times upper limit
of normal (ULN) was 2.4% for patients treated with SAPHRIS 10 mg twice daily
versus none for the other SAPHRIS dose groups and placebo-treated patients.
Prolactin: In short-term,
placebo-controlled adult schizophrenia trials, the mean decreases in prolactin
levels were 6.5 ng/mL for SAPHRIS-treated patients compared to 10.7 ng/mL for
placebo-treated patients. The proportion of patients with prolactin elevations
≥ 4 times ULN (at Endpoint) were 2.6% for SAPHRIS-treated patients versus
0.6% for placebo-treated patients. In short-term, placebo-controlled bipolar
mania adult trials, the mean increase in prolactin levels was 6.7ng/mL for
SAPHRIS-treated patients compared to a decrease of 1.0 ng/mL for
placebo-treated patients. The proportion of patients with prolactin e
