Suicidal ideation and behavior, including completed
suicides, have occurred in patients treated with SILIQ. Prior to prescribing
SILIQ, weigh the potential risks and benefits in patients with a history of
depression and/or suicidal ideation or behavior. Patients with new or worsening
suicidal ideation and behavior should be referred to a mental health
professional, as appropriate. Advise patients and caregivers to seek medical
attention for manifestations of suicidal ideation or behavior, new onset or worsening
depression, anxiety, or other mood changes [see WARNINGS AND PRECAUTIONS].
Because of the observed suicidal behavior in subjects
treated with SILIQ, SILIQ is available only through a restricted program under
a Risk Evaluation and Mitigation Strategy (REMS) called the SILIQ REMS Program [see
WARNINGS AND PRECAUTIONS].
DESCRIPTION
Brodalumab is a human monoclonal IgG2κ antibody
directed against human interleukin-17 receptor A (IL-17RA). It is expressed in
a Chinese Hamster Ovary (CHO) cell line. Brodalumab is comprised of 1312 amino
acids and has an estimated molecular mass of 144,000 Daltons.
SILIQ (brodalumab) Injection is a sterile,
preservative-free, clear to slightly opalescent, colorless to slightly yellow
solution, delivered via subcutaneous injection. A few translucent to white,
amorphous particles may be present. SILIQ is supplied in a single-dose 2.25 mL
syringe made from type 1 glass with stainless steel 27G x ½” needle. Each SILIQ
single-dose prefilled syringe delivers 1.5 mL of solution containing 210 mg of
brodalumab formulated in glutamate (6.5 mg), polysorbate 20 (0.15 mg), proline
(36 mg), and Water for Injection, USP at pH 4.8.
Indications & Dosage
INDICATIONS
SILIQ™ is indicated for the treatment of moderate to
severe plaque psoriasis in adult patients who are candidates for systemic
therapy or phototherapy and have failed to respond or have lost response to
other systemic therapies.
DOSAGE AND ADMINISTRATION
Dosage
The recommended SILIQ dose is 210 mg administered by
subcutaneous injection at Weeks 0, 1, and 2 followed by 210 mg every 2 weeks.
If an adequate response has not been achieved after 12 to
16 weeks of treatment with SILIQ, consider discontinuing therapy. Continued
treatment beyond 16 weeks in patients who have not achieved an adequate
response is not likely to result in greater success.
Tuberculosis Assessment Prior To Initiation of SILIQ
Evaluate patients for tuberculosis (TB) infection prior
to initiating treatment with SILIQ [see WARNINGS AND PRECAUTIONS].
Important Administration Instructions
Administer SILIQ subcutaneously. Each prefilled syringe
is for single-dose only.
Instruct patients to review the Medication Guide before
use (see Medication Guide). SILIQ is intended for use under the guidance
and supervision of a healthcare professional. Patients may self-inject SILIQ
when deemed appropriate by a healthcare professional and after proper training
in subcutaneous injection technique using the prefilled syringe.
Advise patients who are self-administering to inject the
full dose and to read the Instructions for Use before administration (see
Instructions for Use).
Do not inject SILIQ into areas where the skin is tender,
bruised, red, hard, thick, scaly, or affected by psoriasis.
Preparation Of SILIQ Prefilled Syringe
Allow SILIQ prefilled syringe to reach room temperature
(approximately 30 minutes) before injecting. Do not warm in any other way. Do
not remove the gray needle cap on the prefilled syringe while allowing it to
reach room temperature.
Visually inspect SILIQ for particles and discoloration
prior to administration. SILIQ is a clear to slightly opalescent, colorless to
slightly yellow solution. A few translucent to white, amorphous proteinaceous
particles may be present. Do not use SILIQ if it is cloudy or discolored or if
foreign matter is present.
Instruct patients to use the prefilled syringe and to
inject the full amount (1.5 mL), which provides 210 mg of SILIQ, according to
the directions provided in the Instructions for Use [see Instructions for
Use].

SIDE EFFECTS
The following serious adverse reactions are discussed in
greater detail in other sections of labeling:
Suicidal Ideation and Behavior [see WARNINGS AND
PRECAUTIONS]
Infections [see WARNINGS AND PRECAUTIONS]
Crohn's Disease [see CONTRAINDICATIONS, WARNINGS
AND PRECAUTIONS]
Clinical Trial 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.
The overall safety population included 4558 subjects
(3066 SILIQ, 613 ustekinumab, 879 placebo) in controlled clinical trials and
open-label extension studies. The majority of subjects were male (69%), white
(91%), and aged 40-64 years old ÃÂ (58%). One-third of subjects reported previous
biologic use prior to enrollment. Across the clinical development program, 4464
subjects received at least one dose of SILIQ; 3755 subjects were exposed to
SILIQ for at least 1 year.
Weeks 0 to 12: Data from one multicenter,
randomized, placebo-controlled trial (Trial 1), two multicenter, randomized,
placebo-and active-controlled trials (Trials 2 and 3), and one dose-finding
trial (Trial 4) in plaque psoriasis were pooled to evaluate the safety of SILIQ
(210 mg weekly at Weeks 0, 1, and 2, followed by treatments every 2 weeks
[Q2W]) compared to placebo for up to 12 weeks after treatment initiation.
During the 12-week, randomized treatment period, about 1%
of the subjects in the treatment groups (SILIQ, ustekinumab and placebo)
discontinued treatment because of adverse events. Adverse events leading to
discontinuation of SILIQ included neutropenia, arthralgia, and urticaria. The
proportion of subjects who developed serious adverse events was similar among
the SILIQ, ustekinumab, and placebo groups.
Table 1 summarizes the adverse reactions that occurred at
a rate of at least 1% and at a higher rate in the SILIQ 210 mg Q2W group than
in the placebo group during the 12-week randomized treatment period of the
pooled trials.

b Trials 2 and 3 included the active comparator, ustekinumab.
Adverse reactions that occurred in less than 1% of
subjects in the SILIQ group through Week 12 were conjunctivitis and candida
infections (including oral [0.2%], genital [0.1%], and esophageal [0.1%] versus
none in the placebo group).
Week 0 to End of Trial: Through Week 52,
exposure-adjusted rates of serious adverse events were similar between subjects
treated with SILIQ and those treated with ustekinumab. Through the end of the
trial, the exposure-adjusted rates of treatment-emergent serious adverse events
were similar to those seen in the 52-week period in the subjects treated with
SILIQ.
Specific Adverse Reactions
Suicidal Ideation and Behavior
During the 12-week randomized treatment period in the
pooled trials, one subject in the SILIQ group attempted suicide and none in the
placebo or ustekinumab groups. From initiation through Week 52 of the trials,
suicidal ideation or behavior occurred in 7 of 4019 subjects (0.2 per 100
subject-years) treated with SILIQ and in 2 of 613 subjects (0.4 per 100
subject-years) treated with ustekinumab.
During the course of the clinical trials for plaque
psoriasis, suicidal ideation or behavior occurred in 34 of 4464 subjects
treated with SILIQ (0.37 per 100 subject-years). Eight of the 10 subjects who
attempted or completed suicide had a history of depression and/or suicidal
ideation or behavior [see WARNINGS AND PRECAUTIONS].
Infections
During the 12-week randomized treatment period,
infections occurred in 25.4% of the SILIQ group compared to 23.4% of the
placebo group. The majority of infections consisted of nasopharyngitis, upper
respiratory tract infection, pharyngitis, urinary tract infections, bronchitis,
and influenza, and did not necessitate treatment discontinuation. The SILIQ
group had a higher rate of fungal infections compared to the placebo group
(1.8% vs 0.9%). The fungal infections were primarily non-serious skin and mucosal
candida infections [see WARNINGS AND PRECAUTIONS].
Neutropenia
During the 12-week randomized treatment period,
neutropenia occurred in 0.7% of subjects in the SILIQ group. Most adverse
reactions of neutropenia were transient. In subjects with normal absolute
neutrophil count (ANC) at baseline, a reduction in ANC occurred in 6.8% of
subjects in the SILIQ group, compared to 3.3% in the ustekinumab group, and
3.6% in the placebo group. Neutropenia ≥ Grade 3 ( < 1000/mm²)
occurred in 0.5% of subjects in the SILIQ group compared to 0.2% of subjects in
the ustekinumab group and none in the placebo group. From Week 0 to end of
trial, the exposure-adjusted rate of treatment-emergent neutropenia was 0.4 per
100 subject-years (0.1 per 100 subject-years were ≥ Grade 3). No serious
infections were associated with cases of neutropenia.
Immunogenicity
As with all therapeutic proteins, there is potential for
immunogenicity with SILIQ. Approximately 3% of subjects treated with SILIQ
developed antibodies to brodalumab through the 52-week treatment period. Of the
subjects who developed antibodies to brodalumab, none had antibodies that were
classified as neutralizing. However, the assay to test for neutralizing
antibodies had limitations detecting neutralizing antibodies in the presence of
brodalumab; therefore, the incidence of neutralizing antibody development could
be underestimated.
The detection of antibody formation is highly dependent
on the sensitivity and specificity of the assay. Additionally, the observed
incidence of antibody (including neutralizing antibody) positivity in an assay
may be influenced by several factors, including assay methodology, sample
handling, timing of sample collection, concomitant medications, and underlying
disease. For these reasons, comparison of the incidence of antibodies to SILIQ
with the incidence of antibodies to other products may be misleading.
Drug Interactions
DRUG INTERACTIONS
Live Vaccinations
Avoid use of live vaccines in patients treated with SILIQ
[see WARNINGS AND PRECAUTIONS].
CYP450 Substrates
The formation of CYP450 enzymes can be altered by
increased levels of certain cytokines (e.g., IL-1, IL-6, IL-10, TNFα, IFN)
during chronic inflammation. Treatment with SILIQ may modulate serum levels of
some cytokines.
Therefore, upon initiation or discontinuation of SILIQ in
patients who are receiving concomitant drugs which are CYP450 substrates,
particularly those with a narrow therapeutic index, consider monitoring for
effect (e.g., for warfarin) or drug concentration (e.g., for cyclosporine) and
consider dosage modification of the CYP450 substrate [see CLINICAL
PHARMACOLOGY].
Warnings & Precautions
WARNINGS
Included as part of the PRECAUTIONS section.
PRECAUTIONS
Suicidal Ideation And Behavior
Suicidal ideation and behavior, including 4 completed
suicides, occurred in subjects treated with SILIQ in the psoriasis clinical
trials. There were no completed suicides in the 12-week placebo-controlled
portion of the trials. SILIQ users with a history of suicidality or depression
had an increased incidence of suicidal ideation and behavior as compared to
users without such a history [see ADVERSE REACTIONS]. A causal
association between treatment with SILIQ and increased risk of suicidal
ideation and behavior has not been established.
Prescribers should weigh the potential risks and benefits
before using SILIQ in patients with a history of depression or suicidality.
Patients with new or worsening symptoms of depression or suicidality should be
referred to a mental health professional, as appropriate. Advise patients and
caregivers to seek medical attention for manifestations of suicidal ideation
and behavior, new onset or worsening depression, anxiety, or other mood
changes. Prescribers should also reevaluate the risks and benefits of
continuing treatment with SILIQ if such events occur.
Because of the observed suicidal ideation and behavior in
subjects treated with SILIQ, if an adequate response to SILIQ has not been
achieved within 12 to 16 weeks, consider discontinuing therapy.
SILIQ is available only through a restricted program
under a REMS [see SILIQ REMS Program].
SILIQ REMS Program
SILIQ is available only through a restricted program
under a REMS called the SILIQ REMS Program because of the observed suicidal
ideation and behavior in subjects treated with SILIQ [see Suicidal Ideation And Behavior].
Notable requirements of the SILIQ REMS Program include
the following:
Prescribers must be certified with the program.
Patients must sign a Patient-Prescriber Agreement Form.
Pharmacies must be certified with the program and must
only dispense to patients who are authorized to receive SILIQ.
Further information, including a list of qualified
pharmacies, is available at www.SILIQREMS.com or by calling the SILIQ REMS
Program Call Center at 855-511-6135.
Infections
SILIQ may increase the risk of infections. In clinical
trials, subjects treated with SILIQ had a higher rate of serious infections than
subjects treated with placebo (0.5% versus 0.2%) and higher rates of fungal
infections (2.4% versus 0.9%). One case of cryptococcal meningitis occurred in
a subject treated with SILIQ during the 12-week randomized treatment period and
led to discontinuation of therapy [see ADVERSE REACTIONS].
During the course of clinical trials for plaque
psoriasis, the exposure-adjusted rates for infections and serious infections
were similar in the subjects treated with SILIQ and those treated with
ustekinumab.
In patients with a chronic infection or a history of
recurrent infection, consider the risks and benefits prior to prescribing
SILIQ. Instruct patients to seek medical help if signs or symptoms of
clinically important chronic or acute infection occur. If a patient develops a
serious infection or is not responding to standard therapy for the infection,
monitor the patient closely and discontinue SILIQ therapy until the infection
resolves.
Risk For Latent Tuberculosis Reactivation
Evaluate patients for tuberculosis (TB) infection prior
to initiating treatment with SILIQ. Do not administer SILIQ to patients with
active TB infection. Initiate treatment for latent TB prior to administering
SILIQ.
Consider anti-TB therapy prior to initiation of SILIQ in
patients with a past history of latent or active TB in whom an adequate course
of treatment cannot be confirmed. Closely monitor patients receiving SILIQ for
signs and symptoms of active TB during and after treatment.
Crohn's Disease
In psoriasis trials, which excluded subjects with active
Crohn's disease, Crohn's disease occurred in one subject during treatment with
SILIQ and led to discontinuation of therapy. In other trials, exacerbation of
Crohn's disease was observed with SILIQ use.
SILIQ is contraindicated in patients with Crohn's
disease.
Discontinue SILIQ if the patient develops Crohn's disease
while taking SILIQ.
Immunizations
Avoid use of live vaccines in patients treated with
SILIQ. No data are available on the ability of live or inactive vaccines to
elicit an immune response in patients being treated with SILIQ.
Patient Counseling Information
Advise the patient to read the FDA-approved patient
labeling (Medication Guide and Instructions for Use) before the patient starts
using SILIQ, and each time the prescription is renewed, as there may be new
information they need to know.
Suicidal Thoughts And Behavior
Instruct patients and their caregivers to monitor for the
emergence of suicidal thoughts and behavior and promptly seek medical attention
if the patient experiences suicidal thoughts, new or worsening depression,
anxiety, or other mood changes [see WARNINGS AND PRECAUTIONS].
Instruct patients to carry the wallet card provided and
to call the National Suicide Prevention Lifeline at 1-800-273-8255 if they
experience suicidal thoughts.
SILIQ REMS Program
Because of the observed suicidal thoughts and behavior in
subjects treated with SILIQ, SILIQ is available only through a restricted
program called the SILIQ REMS Program [see WARNINGS AND PRECAUTIONS]. Inform
the patient of the following:
Patients must enroll in the program [see WARNINGS AND
PRECAUTIONS].
Patients will be given a SILIQ Patient Wallet Card that
they should carry with them at all times. This card describes symptoms which,
if experienced, should prompt the patient to immediately seek medical
evaluation. Advise the patient to show the SILIQ Patient Wallet Card to other
treating healthcare providers.
SILIQ is available only from certified pharmacies
participating in the program. Therefore, provide patients with the telephone
number and website for information on how to obtain the product.
Infections
Inform patients that SILIQ may lower the ability of their
immune system to fight infections. Instruct patients of the importance of
communicating any history of infections to their healthcare providers and to
contact their healthcare providers if they develop any signs or symptoms of
infection [see WARNINGS AND PRECAUTIONS].
Crohn's Disease
Instruct patients to seek medical advice if they develop
signs and symptoms of Crohn's disease [see WARNINGS AND PRECAUTIONS].
Instructions For Injection
Instruct the patient to perform the first self-injection
under the guidance and supervision of a qualified healthcare professional for
proper training in subcutaneous injection technique. Instruct patients who are
self-administering to inject the full dose of SILIQ [see DOSAGE AND
ADMINISTRATION and Instructions for Use]. Instruct patients or
caregivers in the technique of proper syringe and needle disposal [see Instructions
for Use].
Nonclinical Toxicology
Carcinogenesis, Mutagenesis, Impairment Of Fertility
Animal studies have not been conducted to evaluate the
carcinogenic or mutagenic potential of SILIQ. The published literature is mixed
on the potential effects on malignancy risk due to the inhibition of the
IL-17RA, the pharmacological action of SILIQ. Some published literature
suggests that IL-17A directly promotes cancer cell invasion, which suggests a
potential beneficial effect of SILIQ. However, other reports indicate IL-17A
promotes T-cell mediated tumor rejection, which suggests a potential adverse
effect by SILIQ. However, inhibition of the IL-17RA with SILIQ has not been
studied in these models. Therefore, the relevance of experimental findings in
these models for malignancy risk in humans is unknown.
In cynomolgus monkeys, there were no effects on fertility
parameters such as changes in reproductive organs or sperm analysis following
subcutaneous administration of brodalumab at dose levels up to 90 mg/kg/week
for six months (26 times the MRHD on a mg/kg basis). The monkeys were not mated
in this study to evaluate effects on fertility.
Use In Specific Populations
Pregnancy
Risk Summaruy
There are no human data on SILIQ use in pregnant women to
inform a drug associated risk. Human IgG antibodies are known to cross the
placental barrier; therefore, SILIQ may be transmitted from the mother to the
developing fetus. In a combined embryofetal development and pre-and post-natal
development study, no adverse developmental effects were observed in infants
born to pregnant monkeys after subcutaneous administration of brodalumab during
organogenesis through parturition at doses up to 26 times the maximum
recommended human dose (MRHD)[see Data].
The estimated background risk of major birth defects and
miscarriage for the indicated population is unknown. In the U.S. general
population, the estimated background risk of major birth defects and
miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%,
respectively.
Data
Animal Data
A combined embryofetal development and pre-and post-natal
development study was conducted in cynomolgus monkeys administered brodalumab.
No brodalumab-related effects on embryofetal toxicity or malformations, or on
morphological, functional or immunological development were observed in infants
from pregnant monkeys administered weekly subcutaneous doses of brodalumab up
to 26 times the MRHD from the beginning of organogenesis to parturition (on a
mg/kg basis of 90 mg/kg/week).
Lactation
Risk Summary
There are no data on the presence of brodalumab in human
milk, the effects on the breastfed infant, or the effects on milk production.
Brodalumab was detected in the milk of lactating cynomolgus monkeys. The
developmental and health benefits of breastfeeding should be considered along
with the mother's clinical need for SILIQ and any potential adverse effects on
the breastfed infant from SILIQ or from the underlying maternal condition.
Pediatric Use
The safety and effectiveness of SILIQ have not been
evaluated in pediatric patients.
Geriatric Use
Of the 3066 plaque psoriasis subjects initially
randomized to SILIQ in clinical trials, 192 (6%) were ≥ 65 years old and
no subjects were ≥ 75 years old. Although no differences in safety or
efficacy were observed between older and younger subjects, the number of subjects
aged 65 years and older was not sufficient to determine whether they responded
differently from younger subjects [see CLINICAL PHARMACOLOGY].
Overdosage & Contraindications
OVERDOSE
No information provided.
CONTRAINDICATIONS
SILIQ is contraindicated in patients with Crohn's disease
because SILIQ may cause worsening of disease [see WARNINGS AND PRECAUTIONS].
Clinical Pharmacology
CLINICAL PHARMACOLOGY
Mechanism Of Action
Brodalumab is a human monoclonal IgG2 antibody that
selectively binds to human IL-17RA and inhibits its interactions with cytokines
IL-17A, IL-17F, IL-17C, IL-17A/F heterodimer and IL-25. IL-17RA is a protein
expressed on the cell surface and is a required component of receptor complexes
utilized by multiple IL-17 family cytokines. Blocking IL17RA inhibits IL-17
cytokine-induced responses including the release of pro-inflammatory cytokines
and chemokines.
Pharmacodynamics
Elevated levels of IL-17A, IL-17C and IL-17F are found in
psoriatic plaques. Serum IL-17A levels, measured at Weeks 12, 24, and 48 of
SILIQ 210 mg every 2 weeks of treatment, were higher than the baseline levels
in subjects with moderate to severe plaque psoriasis. The relationship between
the pharmacodynamic activity and the mechanism(s) by which brodalumab exerts
its clinical effects is unknown.
Pharmacokinetics
Absorption
Following a single subcutaneous dose of 210 mg in
subjects with plaque psoriasis, brodalumab reached peak mean (±SD) serum
concentration (Cmax) of 13.4±7.3 mcg/mL by approximately 3 days post dose. The
mean (±SD) area-under-theconcentration-time curve (AUC) of brodalumab was
111±64 mcg•day/mL.
Following multiple subcutaneous doses of 210 mg every 2
weeks, steady-state was achieved by Week 4. The mean (±SD) Cmax was 20.6±14.6
mcg/mL and the mean (±SD) AUC over the two week dosing interval was 227±167
mcg•day/mL.
Following subcutaneous administration, brodalumab
bioavailability was approximately 55%.
Distribution
Following a single subcutaneous administration of
brodalumab 210 mg in subjects with plaque psoriasis, the mean (±SD) apparent
volume of distribution (Vz/F) of brodalumab was 8.9±9.4 L.
Elimination
The metabolic pathway of brodalumab has not been
characterized. As a human monoclonal IgG2 antibody, brodalumab is expected to
be degraded into small peptides and amino acids via catabolic pathways in a
manner similar to endogenous IgG.
Following a single subcutaneous administration of
brodalumab 210 mg in subjects with plaque psoriasis, the mean (±SD) apparent
total clearance (CL/F) was 3.0±3.5 L/day. The clearance of brodalumab increased
with decreasing doses due to nonlinear elimination.
Dose Linearity
Brodalumab exhibited non-linear pharmacokinetics with
exposures that increased greater than dose-proportionally over a dose range
from 140 mg (approximately 0.67 times the recommended dose) to 350 mg
(approximately 1.67 times the recommended dose) following subcutaneous
administrations in subjects with plaque psoriasis.
Weight
Brodalumab trough concentrations were lower in subjects
with higher body weight.
Specific Populations
Hepatic or Renal Impairment
No trials were conducted to assess the effect of hepatic
or renal impairment on the pharmacokinetics of brodalumab.
Age: Geriatric Population
Population pharmacokinetic analysis indicated that age
did not significantly influence the clearance of brodalumab in subjects with
plaque psoriasis. Subjects who were 65 years or older had a similar brodalumab
clearance as compared to subjects less than 65 years old.
Drug Interaction Studies
In subjects with plaque psoriasis, one week following a
single subcutaneous administration of 210 mg brodalumab, the exposure of
midazolam (CYP3A4 substrate) was increased by 24% [see DRUG INTERACTIONS].
Clinical Studies
Three multicenter, randomized, double-blind, controlled
trials (Trials 1, 2, and 3) enrolled a total of 4373 subjects 18 years of age
and older with at least a 6-month history of moderate to severe plaque
psoriasis, defined as having a minimum affected body surface area (BSA) of 10%,
a Psoriasis Area and Severity Index (PASI) score ≥ 12, a static
Physician's Global Assessment (sPGA) score ≥ 3 in the overall assessment
(plaque thickness/induration, erythema, and scaling) of psoriasis on a severity
scale of 0 to 5, and who were candidates for systemic therapy or phototherapy.
In all three trials, subjects were randomized to subcutaneous treatment with
placebo or SILIQ 210 mg at Weeks 0, 1, and 2, followed by treatments every 2
weeks [Q2W] through Week 12. In the two active comparator trials (Trials 2 and
3), subjects randomized to ustekinumab received a 45 mg dose if their weight
was less than or equal to 100 kg and a 90 mg dose if their weight was greater
than 100 kg at Weeks 0, 4, and 16, followed by the same dose every 12 weeks.
All three trials assessed the change from baseline to
Week 12 compared to placebo in the two co-primary endpoints: 1) PASI 75, the
proportion of subjects who achieved at least a 75% reduction in the PASI
composite score that takes into consideration both the percentage of body
surface area affected and the nature and severity of psoriatic changes
(induration, erythema, and scaling) within the affected region, and 2) the
proportion of subjects with an sPGA of 0 (clear) or 1 (almost clear), and at
least a 2-point improvement from baseline. In Trials 2 and 3, comparisons were
also made to ustekinumab for the primary endpoint of the proportion of subjects
who achieved a reduction in PASI score of 100% (PASI 100) from baseline at Week
12.
Other evaluated outcomes included the proportion of
subjects who achieved an sPGA of 0 (clear) at Week 12, and the proportion of
subjects who achieved a Psoriasis Symptom Inventory (PSI) score of 0 (not at
all) or 1 (mild) on every item (itch, redness, scaling, burning, stinging,
cracking, flaking, and pain) at Week 12. Baseline demographics and disease
characteristics were generally consistent across all treatment groups in all
three trials. Subjects were predominantly men (69%) and white (91%), with a
mean age of 45 years. The mean baseline body weight was 90.5 kg and 28% of
subjects had body weight greater than 100 kg. The baseline PASI score ranged
from 9.4 to 72 (median: 17.4) and the baseline affected BSA ranged from 10 to
97% (median: 21%). Baseline sPGA scores ranged from “3 (moderate)” (58%) to “5
(very severe)” (5%).
Approximately 21% of subjects had a history of psoriatic
arthritis. Approximately 30% of subjects had previously received a biologic
therapy and 12% of subjects had failed previous biologic therapy.
Clinical Response At Week 12
The results of Trials 1, 2, and 3 are presented in Table 2.
Table 2: Efficacy Results at Week 12 in Adults with
Plaque Psoriasis in Trials 1, 2, and 3 (NRIa)
Examination of age, gender, race, use of prior systemic
or phototherapy, and use of prior biologics did not identify differences in
response to SILIQ among these subgroups.
At Week 12, compared to subjects in the placebo group, a
greater proportion of subjects in SILIQ 210 mg Q2W group achieved a Psoriasis
Symptom Inventory (PSI) score of 0 (not at all) or 1 (mild) on every item
(itch, redness, scaling, burning, stinging, cracking, flaking, pain).
Maintenance Of Effect
In Trial 1, subjects randomized to receive SILIQ and who
were responders at Week 12 (i.e., sPGA of 0 or 1) were re-randomized to receive
either placebo or SILIQ. Among responders at Week 12, 83% (69/83) of subjects
re-randomized to continued treatment with SILIQ 210 mg Q2W maintained this response
(sPGA of 0 or 1) at Week 52 compared to none (0/84) who were re-randomized to
placebo and withdrawn from SILIQ. In addition, 87% (72/83) of subjects
re-randomized to continued treatment with SILIQ 210 mg Q2W achieved PASI 75
response at Week 52 compared to none (0/84) who were re-randomized to placebo
and withdrawn from SILIQ.
Trials 2 and 3 included a re-randomized phase during
which subjects originally randomized to receive SILIQ during the first 12 weeks
were re-randomized to one of four SILIQ regimens at the Week 12 visit and
placebo subjects were crossed over to receive SILIQ 210 mg Q2W. Subjects
receiving ustekinumab continued the same treatment until crossed over at Week
52 to SILIQ 210 mg Q2W. For sPGA 0 or 1 responders at Week 12, the percentage
of subjects who maintained this response at Week 52 was 79% for subjects
treated with SILIQ 210 mg Q2W. For PASI 100 responders at Week 12, 72% of the
subjects who continued on SILIQ 210 mg Q2W maintained the response at Week 52.

you the injection)
Clean your injection site with an alcohol wipe. Let your
skin dry.
Do not touch this area again before injecting.
Choose a different site each time you give yourself an
injection. If you want to use the same injection site, make sure it is not the
same spot on the injection site that you used for a previous injection.
