Approval of STELARA(TM) in Canada Marks Advancement in Treatment of Moderate to Severe Plaque Psoriasis

    - In clinical studies, patients receiving STELARA showed sustained
    improvements in psoriasis and quality of life measures through 76 weeks -

    TORONTO, Dec. 15 /CNW/ - Canadians living with moderate to severe plaque
psoriasis, a chronic and often debilitating inflammatory disease, now have a
new treatment option with the approval of STELARA(TM) (ustekinumab). STELARA,
which is self-injected every 12 weeks following two starter doses at weeks 0
and 4, has demonstrated significant efficacy in clinical studies involving
more than 3,000 participants from around the world. In Canada, STELARA is
marketed by Janssen-Ortho Inc.
    The recommended dose of STELARA is 45 mg administered at Weeks 0 and 4,
then every 12 weeks thereafter. Alternatively, 90 mg may be used in patients
with a body weight greater than 100 kg. Treatment is intended for use under
the guidance and supervision of a physician. STELARA is indicated for adult
patients who are candidates for phototherapy or systemic therapy.(1)
    "This is an exciting new advancement in the management of psoriasis with
approximately two-thirds of adults receiving STELARA having achieved at least
75 per cent improvement in their psoriasis within the first 12-week course of
dosing in clinical trials(2)," said Dr. Richard Langley, Associate Professor
of Medicine in Dermatology, Director of Dermatology Research at Dalhousie
University, and study investigator. "Every twelve-week dosing makes STELARA a
much-anticipated therapeutic option for patients living with moderate to
severe psoriasis."
    A human monoclonal antibody, STELARA targets the activity of cytokines
interleukin-12 (IL-12) and interleukin-23 (IL-23), naturally occurring
proteins that are important in regulating the immune system and that are
thought to be associated with some immune related inflammatory diseases
including plaque psoriasis. The treatment regulates IL-12 and IL-23
interactions, reducing inflammation in the skin cells and helping to control
the signs and symptoms of psoriasis.(1)

    Data Shows Improvements to Physical and Quality of Life Burdens

    STELARA was studied in two pivotal phase III clinical trials.(3) The
trials demonstrated that the majority of patients with moderate to severe
plaque psoriasis who received STELARA sustained, clinically significant
improvement in their disease severity. At week 12, the primary endpoint of
both studies, 66 percent to 76 percent of patients who received just two doses
of STELARA, 45 mg or 90 mg, respectively, at weeks 0 and 4, achieved PASI 75
(75 per cent improvement on the Psoriasis Activity and Severity Index)
compared with 3 to 4 per cent of patients receiving placebo (p less than
0.001). Long-term results from these studies through 76 weeks were published
in The Lancet in May 2008.
    Rates of serious adverse events, including serious infections,
malignancies and cardiovascular event, were low and consistent with the
expected background rates. The most common adverse events in Phase 3 clinical
trials were arthralgia, cough, headache, injection site erythema,
nasopharyngitis and upper respiratory tract infection.
    An additional Phase 3 study evaluated the safety and efficacy of STELARA
compared with etanercept(*) in 903 patients with chronic plaque psoriasis
(etanercept=347, STELARA 45 mg=209, STELARA 90 mg=347)(1). Patients were
randomized to receive STELARA 45 mg or 90 mg doses at weeks 0 and 4, while the
etanercept group received twice-weekly doses of 50 mg over 12 weeks. The
primary endpoint of the study was the proportion of patients who achieved a
PASI 75 at week 12. Study results showed that 68 percent and 74 percent of
patients receiving STELARA 45 mg or STELARA 90 mg, respectively, at weeks 0
and 4 achieved PASI 75 compared with 57 percent of patients receiving
twice-weekly doses of etanercept 50 mg over 12 weeks (P=0.012 for STELARA 45
mg; P less than 0.001 for STELARA 90 mg, each compared with etanercept).
    Through week 12, the comparator-controlled portion of the study, the
percentages of study participants experiencing at least one adverse event (AE)
were comparable between the STELARA 45 mg group (66 percent), the STELARA 90
mg group (68 percent) and the etanercept 50 mg group (69 percent). The most
common AEs included nasopharyngitis, headache, upper respiratory tract
infection, back pain, pruritus, fatigue, arthralgia, injection site erythema
and injection site swelling.
    In addition to improvements in physical symptoms, the phase III pivotal
trials also demonstrated clinically meaningful improvements in quality of life
measures, which were significant as early as Week 2 in patients treated with
STELARA (p less than 0.001) in one of the Phase 3 studies and these
improvements were maintained over time with continued dosing.(4)
    "The approval of STELARA is an important milestone for psoriasis
patients," said Christine Jackson, Executive Director of the Canadian Skin
Patient Alliance. "The impact of today's news is significant for psoriasis
patients. These individuals not only need new options to manage their disease,
but it is critical that they have access to these treatments as well."

    About Psoriasis

    Psoriasis is a chronic, recurring and often debilitating inflammatory
disease that affects approximately one million Canadian adults.(5) It is a
common immune mediated skin disease in adults and one of the oldest skin
conditions known to man.(6) The symptoms of psoriasis usually appear between
the ages of 15 and 35 with 75 per cent of people developing it before the age
of 40.(7)
    Plaque psoriasis is the most common form and affects approximately 80 per
cent of those suffering from the condition.(8) It usually results in painful,
itchy, sore patches of thick, red or inflamed skin covered with silvery scales
known as plaques. Plaques can occur anywhere on the body - most commonly on
the elbows, knees, lower back and the area around the bellybutton. Severity
ranges from minor localized patches to complete body coverage.
