FDA Accepts Application Requesting Approval of
REMICADE(R) in the Treatment of Moderate to Severe Plaque Psoriasis
Supporting Data from Two Phase 3 Studies Show Rapid and Significant Clearance
of Skin Disease.
MALVERN, Pa., Nov. 7 /PRNewswire/ -- Centocor, Inc. announced today that
the U.S. Food and Drug Administration (FDA) has accepted its filing of a
supplemental Biologics License Application (sBLA) for the use of REMICADE
(infliximab) in the treatment of moderate to severe plaque psoriasis. It is
estimated that nearly two million Americans suffer from moderate to severe
psoriasis, a chronic, immune-mediated inflammatory disease that can be both
physically and emotionally debilitating.(1)
The acceptance of the sBLA file for psoriasis follows the September 2005
European Commission approval of REMICADE for the treatment of moderate to
severe plaque psoriasis in adults who failed to respond to, or have a
contraindication to, or are intolerant of other systemic therapy including
cyclosporine, methotrexate or psoralen plus ultraviolet light A (PUVA). In
May 2005 the FDA approved REMICADE for reducing signs and symptoms of active
arthritis in patients with psoriatic arthritis. Acceptance of the sBLA filing
does not mean that a license has been issued for this indication nor does it
represent any evaluation of the adequacy of the data submitted in the
sBLA.
"The results we have seen in dermatologic clinical trials evaluating
REMICADE have been very encouraging," said Cynthia Guzzo, M.D., Executive
Director, Immunology, Centocor, Inc. "The continued study of REMICADE for the
treatment of psoriatic disease demonstrates the commitment of Centocor to the
dermatology community and to advancing treatment expectations for physicians
and patients."
The sBLA filing is based on results of two phase 3, multi-center,
randomized, double-blind, placebo-controlled trials, European Infliximab for
Psoriasis [REMICADE] Efficacy and Safety Study (EXPRESS) and Evaluation of
Infliximab for Psoriasis in a [REMICADE] Efficacy and Safety Study (EXPRESS
II).
About EXPRESS
EXPRESS was a phase 3, multi-center, randomized, double-blind, placebo-controlled trial evaluating the efficacy and safety of REMICADE induction and
maintenance therapy in 378 patients with moderate to severe plaque psoriasis
who were candidates for phototherapy or systemic therapy. Patients received
either REMICADE 5 mg/kg or placebo administered at weeks 0, 2 and 6, followed
by maintenance treatment every 8 weeks. The REMICADE group continued on
maintenance treatments every 8 weeks. Beginning at week 24, patients
randomized to the placebo group were crossed over to receive REMICADE therapy
through week 46.
Results from EXPRESS showed that a majority of REMICADE-treated patients
achieved clinically significant levels of skin clearance. At week 10, 80
percent of patients receiving REMICADE achieved at least 75 percent
improvement frombaseline in psoriasis as measured by the Psoriasis Area and
Severity Index (PASI 75), and 57 percent achieved PASI 90, near complete skin
clearance, versus 3 percent and 1 percent of patients receiving placebo,
respectively (P < 0.001).
Results were maintained at week 24 with 82 percent of REMICADE-treated
patients achieving PASI 75, and 58 percent of patients achieving PASI 90
responses, versus 4 percent and 1 percent of patients receiving placebo,
respectively (P < 0.001). The majority of patients maintained significant
improvement in psoriasis through week 50 with continued REMICADE treatment.
In EXPRESS, through week 24, AEs occurred at a higher incidence in the
REMICADE group (82 percent) compared with the placebo group (71 percent). The
only clinically significant laboratory abnormalities that occurred more
frequently in the REMICADE group compared with placebo were elevated liver
enzyme tests. There were more serious AEs (6 percent), including one fatal
infection, in the REMICADE group than in the placebo group (3 percent). AEs
observed were generally consistent with those described in the prescribing
information, including information regarding serious infections. Please see
"Important Safety Information" below.
About EXPRESS II
EXPRESS II was a phase 3, multi-center, randomized, double-blind, placebo-controlled trial examining the safety and efficacy of REMICADE in 835 patients
with moderate to severe plaque psoriasis who were candidates for phototherapy
or systemic therapy. Patients were randomized to induction doses of REMICADE
3 mg/kg or 5 mg/kg or placebo at weeks 0, 2 and 6. Patients in the active
induction treatment groups were randomized again at week 14 to receive either
scheduled or "as-needed" maintenance treatment at the same dose administered
during the induction phase. Patients in the placebo group were crossed over
at week 16 to receive REMICADE 5 mg/kg at weeks 16, 18 and 22, then every 8
weeks through week 46.
EXPRESS II independently substantiated the EXPRESS study findings. In
addition, the EXPRESS II study showed that scheduled maintenance treatment
with REMICADE resulted in greater long-term control of skin clearance compared
with "as-needed" therapy regimens. In the study, at week 10, 70 percent of
patients receiving REMICADE 3 mg/kg and 75 percent of patients receiving
REMICADE 5 mg/kg achieved at least PASI 75, versus 2 percent of patients
receiving placebo (P < 0.001). The majority of patients in the scheduled
maintenance groups maintained significant improvement in psoriasis through
week 50 with continued REMICADE treatment. PASI responses were also
accompanied by significant improvements in health-related quality of life.
In EXPRESS II, through week 14 (the placebo-controlled period), AEs
occurred at a higher incidence in the REMICADE groups (63 percent and 69
percent in the 3 mg/kg and 5 mg/kg, respectively) compared with the placebo
group (56 percent). The only clinically significant laboratory abnormalities
that occurred more frequently in the REMICADE group compared with placebo were
elevated liver enzyme tests. Serious AEs occurred at rates of 2 percent in
the placebo group, 3 percent in the 5 mg/kg group and 1 percent in the 3 mg/kg
group. AEs observed were generally consistent with those described in the
prescribing information, including information regarding serious infections.

About Psoriasis
Psoriasis is a chronic, immune-mediated disease, which results when skin cells over-produce and accumulate on the surface causing red, scaly plaques
that may itch and bleed. This chronic inflammation is driven in part by tumor
necrosis factor alpha, or TNF-alpha, a cytokine involved in the body's normal
immune response. TNF-alpha is found at increased levels in psoriatic plaques
and plays a crucial part in their formation and continued existence. It is
estimated that two percent of the U.S. population has psoriasis, and about 30
percent of people with psoriasis have cases that are considered moderate to
severe.
About Psoriatic Arthritis
Psoriatic arthritis involves joint pain and swelling that can lead to
debilitation coupled with inflamed, scaly, red patches of psoriasis. Symptoms
may include stiffness and tenderness of the joints and surrounding tissue,
reduced range of motion, nail changes and redness and pain of the eye, or
uveitis. Joints of the hands, wrists, knees, ankles, feet, lower back and
neck are commonly affected. Approximately one million Americans have
psoriatic arthritis, and the disease affects both men and women equally, most
commonly between the ages 30 and 50.
About REMICADE
REMICADE is the global market leader among anti-tumor necrosis factor
alpha (TNF-alpha) therapies and has demonstrated broad clinical utility in
rheumatoid arthritis (RA), Crohn's disease (CD), psoriatic arthritis (PsA),
ulcerative colitis (UC), and ankylosing spondylitis (AS). The safety and
efficacy of REMICADE have been well established in clinical trials over the
past 12 years and through commercial experience with over 600,000 patients
treated worldwide.
In the U.S., REMICADE, in combination with methotrexate, is indicated for reducing signs and symptoms, inhibiting the
progression of structural damage
and improving physical function in patients with moderately to severely active
RA. REMICADE is the only biologic indicated for the treatment of patients
with moderately-to-severely active CD who have had an inadequate response to
conventional therapy. REMICADE is also indicated for reducing the number of
draining enterocutaneous and rectovaginal fistulas and maintaining fistula
closure in patients with fistulizing CD. In December 2004, REMICADE was
approved for reducing signs and symptoms in patients with active AS. On May
13, 2005, REMICADE was approved for reducing signs and symptoms of active
arthritis in patients with PsA. Additionally, on September 15, 2005, REMICADE
was approved for reducing signs and symptoms, achieving clinical remission and
mucosal healing, and eliminating corticosteroid use in patients with
moderately to severely active UC who have had an inadequate response to
conventional therapy. This approval makes REMICADE the first and only
biologic approved for the treatment of moderate to severe UC.
REMICADE is unique among available anti-TNF biologic therapies. Unlike
self-administered therapies that require patients to inject themselves
frequently, REMICADE is the only anti-TNF biologic administered directly by
caregivers in the clinic or office setting. In RA, CD and PsA, REMICADE is a
two-hour infusion administered every 8 weeks, following a standard induction
regimen that requires treatment at weeks 0, 2 and 6. As a result, REMICADE
patients may require as few as six treatments each year. In AS, REMICADE is a
two-hour infusion (5 mg/kg) administered every 6 weeks, following a standard
induction regimen that requires treatment at weeks 0, 2, and 6. In UC,
REMICADE is a two-hour infusion (5 mg/kg) administered every 8 weeks,
following a standard induction regimen that requires treatment at weeks 0, 2,
and 6.
Important Safety Information
Many people with heart failure should not take REMICADE; so prior to treatment you should discuss any heart condition with your doctor. Tell your
doctor right away if you develop new or worsening symptoms of heart failure
(such as shortness of breath or swelling of your ankles or feet). There are
reports of serious infections, including tuberculosis (TB), sepsis and
pneumonia. Some of these infections have been fatal. Tell your doctor if you
have had recent or past exposure to people with TB. Your doctor will evaluate
you for TB and perform a skin test. If you have latent (inactive) TB, your
doctor should begin TB treatment before you start REMICADE. REMICADE can
lower your ability to fight infections, so if you are prone to or have a
history of infections, or develop any signs of an infection such as fever,
fatigue, cough, or the flu while taking REMICADE, tell your doctor right away.
Also tell your doctor if you have lived in a region where histoplasmosis or
coccidioidomycosis is common.
There have been rare cases of serious liver injury in people taking
REMICADE, some fatal. Contact your doctor immediately if you develop symptoms
such as jaundice (yellow skin and eyes), dark brown urine, right-sided
abdominal pain, fever, or severe fatigue.
Blood disorders have been reported, some fatal. Tell your doctor if you develop possible signs of blood disorders such as persistent fever, bruising,
bleeding, or paleness while taking REMICADE. Nervous system disorders have
also been reported. Tell your doctor if you have or have had a disease that
affects the nervous system, or if you experience any numbness, weakness,
tingling, or visual disturbances while taking REMICADE.
Reports of a type of blood cancer called lymphoma in patients on REMICADE
or other TNF blockers are rare but occur more often than expected for people
in general. People who have been treated for rheumatoid arthritis, Crohn's
disease, ankylosing spondylitis, or psoriatic arthritis for a long time,
particularly those with highly active disease may be more prone to develop
lymphoma. Cancers, other than lymphoma, have also been reported. If you take
REMICADE or other TNF blockers, your risk for developing lymphoma or other
cancers may increase. You should also tell your doctor if you have had or
develop lymphoma or other cancers while you are taking REMICADE.
Serious infusion reactions have been reported with REMICADE, including
hives, difficulty breathing, and low blood pressure. Reactions have occurred
during or after infusions. In clinical studies, some people experienced the
following common side effects: respiratory infections (that may include sinus
infections and sore throat), coughing, and stomach pain or mild reactions to
infusion such as rash or itchy skin. Please read important information about
