Novartis presented results of two new studies at AAD: CLEAR study showed Cosentyx™ is significantly superior to Stelara® while two year extended study demonstrated its long term safety and efficacy

  • In the CLEAR study presented at the American Academy of Dermatology (AAD), CosentyxTM showed superiority to Stelara®* across all study endpoints up to Week 16, including PASI 100 and onset of action1
  • New data at AAD showed 7 out of 10 psoriasis patients, who were PASI 75 responders at 52 Weeks, had almost clear to clear skin (PASI 90 to PASI 100) after two years of CosentyxTM 300 mg treatment while almost 9 out of 10 psoriasis patients sustained their PASI 75 response2
  • Cosentyx™, an IL-17A inhibitor approved for moderate-to-severe psoriasis in Canada, showed superiority to both Stelara®* and Enbrel®** 1,3  

DORVAL, QC, March 25, 2015 /CNW/ - Novartis announced results from the CLEAR study that demonstrated Cosentyx™ 300 mg (secukinumab) was significantly superior to Stelara®* (ustekinumab), a biologic, in achieving clear or almost clear skin for psoriasis patients1. Novartis also presented two-year results that demonstrated strong and sustained efficacy with Cosentyx™ with a favorable safety profile for the treatment of psoriasis patients2. The data came from the extension study of the pivotal Phase III FIXTURE and ERASURE trials. Both detailed findings were presented in late-breaking research sessions at the 73rd Annual Meeting of the American Academy of Dermatology (AAD) in San Francisco, USA. Cosentyx™ is approved to treat adult patients with moderate-to-severe plaque psoriasis in Canada. 

"As a dermatologist, I see the physical and emotional impact moderate-to-severe plaque psoriasis inflicts on all aspects of a person's life. While psoriasis patients struggle with more than just a skin disease, achieving clear to near clear skin is an ultimate treatment goal for Canadians living with this condition," said Dr. Ron Vender, MD FRCPC, Associate Clinical Professor of Medicine at McMaster University.  "Historically, PASI 75 has been the goal for psoriasis treatments and was used regularly as the primary endpoints in clinical trials. In the CLEAR study, the primary endpoint goal was to measure both treatments capacity to achieve clear to almost clear skin or PASI 90 an important measure of treatment."

In the CLEAR Phase IIIb study, Cosentyx™ met the primary endpoint of showing superiority to Stelara®* as assessed by the Psoriasis Area Severity Index (PASI) 90 response, known as clear to almost clear skin4, at Week 16 (79.0% vs. 57.6%, P<0.0001)1. In addition, completely clear skin (PASI 100) at Week 16 was achieved by significantly more patients treated with Cosentyx™ than those receiving Stelara®* (44.3% vs. 28.4%, P<0.0001)1

"Collaboration between dermatologists at a national and international levels for the CLEAR study has provided an opportunity to discuss psoriasis management advancements and create a network of researchers dedicated to enhance psoriasis care in Canada and around the world," said Dr. Yves Poulin, clinical dermatologist and assistant professor in the Department of Medicine at Laval University. "With CosentyxTM we now have a new treatment option to help these Canadians."

About the CLEAR study
CLEAR (Comparison to assess Long-term Efficacy, sAfety and toleRability of secukinumab vs. ustekinumab), a 52-week, multicenter, randomized, double-blind study, is a head-to-head Phase IIIb study initiated with Cosentyx™, and compares the efficacy, long-term safety and tolerability of Cosentyx™ 300 mg (secukinumab) versus Stelara®* (ustekinumab), in patients with moderate-to-severe plaque psoriasis1. Twenty-four countries across North America including Canada, Europe, Asia and Australia participated in the study, with enrollment reaching 679 patients in record time1.

The primary endpoint measured at Week 16 was PASI 901. Additionally the secondary endpoint measured at Week 4 is PASI 751. PASI 100 at Week 16 was one of the exploratory endpoints1. Week 52 data will follow in due course.

The CLEAR study follows the pivotal Phase III FIXTURE study, which showed Cosentyx™ was superior to Enbrel®** (etanercept) in clearing skin3. Results from the FIXTURE study were first announced in October 2013.

About the A2302E1 Extension Study (CosentyxExtension Study to the FIXTURE and ERASURE studies)
A2302E1 was a multicenter, double-blind, randomized withdrawal extension study to the FIXTURE and ERASURE pivotal Phase III studies. The extension study was conducted to collect long term efficacy, safety and tolerability data on Cosentyx™ in patients who achieved a PASI 75 response to Cosentyx™ at Week 52 of the FIXTURE and ERASURE core studies in moderate-to-severe plaque psoriasis.

Patients who had been receiving Cosentyx™ 300 mg or 150 mg during the maintenance period of the core studies, and who exhibited a PASI 75 response at Week 52 of the core studies, were randomized to continue the same Cosentyx™ dose or receive placebo2. Patients who exhibited partial response (PASI 50 to <PASI 75 response) from baseline at Week 52 of the core studies were also eligible to enter A2302E, but did not enter the randomized withdrawal extension study2. Partial responders instead continued the same treatment dose (Cosentyx™ 300 mg or 150 mg) that they received at the time of completing the maintenance period (Week 52) in the core studies. Non-responders (patients who did not achieve at least a PASI 50 response at Week 52 of the core study) were not eligible to enter any part of this extension study2.

About the FIXTURE and ERASURE studies
FIXTURE (the Full year Investigative eXamination of secukinumab vs. eTanercept Using 2 dosing Regimens to determine Efficacy in psoriasis) and ERASURE (Efficacy of Response And Safety of two fixed secUkinumab REgimens in psoriasis) were part of one  of the largest Phase III program in moderate-to-severe plaque psoriasis completed to date, which involved more than 3,300 patients in over 35 countries3.

FIXTURE and ERASURE assessed the efficacy, safety and tolerability of induction period (at Week 12) and maintenance therapy (at Week 52) with subcutaneous Cosentyx™ 300 mg or 150 mg in patients with moderate-to-severe plaque psoriasis3. Both studies were multicenter, randomized, double-blind, placebo-controlled (FIXTURE: also active controlled), parallel-group Phase III trials involving 1,306 patients and 738 patients with moderate-to-severe plaque psoriasis, respectively3. Each study consisted of a 1-to-4-week screening period, a 12-week induction period, a 40-week maintenance period and an 8-week follow-up period3. FIXTURE was the first full-year blinded, direct comparison of biologic therapies for psoriasis in a Phase III study3.

The co-primary endpoints in both studies, PASI 75 response and Investigator's Global Assessment (IGA mod 2011) 0/1 response at Week 12, were used to demonstrate superiority of Cosentyx™ vs. placebo (p<0.001 for all comparisons)3. Cosentyx™ 300 mg demonstrated significant improvements in PASI 75 at Week 12 (77.1% vs. 44.0% for Enbrel®** vs. 4.9% for placebo in FIXTURE and 81.6% vs. 4.5% for placebo in ERASURE)3.

About PASI
The Psoriasis Area Severity Index or PASI, measures the redness, scaling and thickness of psoriatic plaques and the extent of involvement in each region of the body.

About interleukin-17A (IL-17A)
IL-17A is a naturally occurring cytokine (messenger protein) involved in normal inflammatory and immune responses11,13. IL-17A is highly upregulated in lesional skin in contrast to non-lesional skin of plaque psoriasis patients.

About Psoriasis
Affecting as many as one million Canadians14 and more than 125 million people worldwide15, psoriasis is a chronic autoimmune disease characterized by thick and extensive skin lesions, called plaques, known to cause itching, scaling and pain13. People living with psoriasis reported that these symptoms can negatively impact their quality of life, both psychosocially and physically, which makes daily functioning difficult16,17,18.

Additionally, people with psoriasis are at increased risk for other chronic illnesses17 such a psoriatic arthritis, a type of inflammatory arthritis, which about 30% of people who have psoriasis get18. Psoriasis symptoms can begin at any age, including in childhood, but the disease mainly affects adults20. Symptoms start when a combination of environmental triggers and genetic factors disrupt the lifecycle of skin cells13.

In Canada, the prevalence of psoriasis is estimated at approximately 2%. According to a recent Canadian database study, 85% have chronic plaque psoriasis, 28% of which are considered moderate to severe19.
