Ortho Dermatologics Announces Two-Year Findings From Pivotal Phase 3 Study Of SILIQ(TM) (brodalumab) Injection Data Demonstrating Long-Term Efficacy ProfileData Sets Demonstrating Efficacy and Quality of Life Profile of SILIQ Presented at 2017 Fall Clinical Dermatology Conference
LAVAL, Quebec, Oct. 12, 2017 -- (Healthcare Sales & Marketing Network) -- Ortho Dermatologics, a division of Valeant Pharmaceuticals International, Inc. (NYSE: VRX and TSX: VRX), today announced results from the Pivotal Phase 3 long-term extension study (AMAGINE-2), which demonstrated that SILIQ™ (brodalumab) injection provided sustained high levels of skin clearance (PASI 100) over more than two years in patients with moderate-to-severe psoriasis. These findings are being presented for the first time today at the 2017 Fall Clinical Dermatology Conference in Las Vegas.
"Over a two-year trial, a PASI 100 response rate was reached by 59 percent of a sub-analysis group of patients, demonstrating that SILIQ is a long-term option to treat moderate-to-severe psoriasis," stated Alan Menter, M.D. "This is highly important as patients always fear a flare-up of their psoriasis after initial clearing."
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. SILIQ has a Black Box Warning and a Risk Evaluation and Mitigation Strategy (REMS) due to observed suicidal ideation and behavior in clinical trials. SILIQ is contraindicated in patients with Crohn's disease. Serious infections have occurred; therefore caution should be exercised when considering the use of SILIQ in patients with a chronic infection or a history of recurrent infection. Patients should be evaluated for tuberculosis infection prior to initiating treatment and avoid use of live vaccines.
"For patients with and without prior ustekinumab exposure, SILIQ demonstrated improved skin clearance," said Lawrence J. Green, M.D., associate clinical professor of Dermatology at George Washington University School of Medicine in Washington, D.C. "More than 65 percent of both ustekinumab-naïve and -experienced patients in AMAGINE-1 receiving SILIQ treatment experienced complete clearance (PASI 100) at week 52, making this an excellent solution with proven results for a wide range of patients with moderate-to-severe psoriasis."
Dr. Lawrence Green will be presenting additional information about SILIQ during a product theatre titled, "A New Mechanism of Action in the Treatment of Moderate-to-Severe Plaque Psoriasis" on Thursday, October 12th at 1pm – 2pm PT.
"I am pleased to see the durable efficacy of SILIQ demonstrated through these additional findings," said Joseph C. Papa, chairman and CEO, Valeant. "This dermatologic innovation has been shown to not only provide relief for many patients who suffer from moderate-to-severe plaque psoriasis, but also had an overall positive impact on the quality of life of these patients."
Long-term Efficacy of brodalumab for the Treatment of Moderate-to-Severe Psoriasis Study (AMAGINE-2)
Results from the long-term extension study (AMAGINE-2) found that SILIQ provided sustained high levels of skin clearance (PASI 100) over more than two years in those with moderate-to-severe psoriasis. Further, a sub-analysis group of patients who received any dose of brodalumab in the induction phase and SILIQ during the maintenance and long-term extension (LTE) phases demonstrated similar response rates. Patients who received either study dose of brodalumab in the induction phase and SILIQ throughout the maintenance and LTE phases at week 120, had a PASI 100 response rate of 59.0% (N=178), and PASI 90 response rate of 76.4% (N=178). At week 52, the same set of patients had a PASI 100 response rate of 63.4% (N=290) and PASI 90 response rate of 85.9% (N=290). At week 120, SILIQ continued to be generally well-tolerated with a safety profile comparable to that observed in the 52-week period.
Efficacy of brodalumab in Ustekinumab-Naive and -Experienced Patients With Moderate-to-Severe Plaque Psoriasis (AMAGINE-1) Study
Results of a phase III, multicenter, randomized, double-blind, placebo-controlled study (AMAGINE-1) of the efficacy of brodalumab in a subset of patients with prior exposure to ustekinumab, demonstrated that SILIQ was similarly efficacious with improved skin clearance in patients both with and without prior ustekinumab exposure. Among patients receiving continuous SILIQ, rates of 100% reduction in PASI score (PASI 100) was 65.2% (43 of 66) and 76.5% (n=13 of 17) in ustekinumab-naive and -experienced patients at week 52, respectively. PASI 90 were 75.8% (50 of 66) in ustekinumab-naive and 88.2% (15 of 17), in ustekinumab-experienced patients.
Impact of brodalumab Treatment on Psoriasis Symptom Severity and Improvements in Health-Related Quality of Life Study
Psoriasis symptoms have a significant negative impact on health-related quality of life, impairing physical functioning and well-being. Previously, data has shown that treatment with SILIQ provided rapid improvement in Psoriasis Area and Severity Index (PASI) and psoriasis symptoms in patients with moderate-to-severe psoriasis. This improvement with SILIQ can also be demonstrated by comparing baseline data with measurements at week 12 in terms of improvement in psoriasis symptom inventory scores (PSI) and Dermatology Quality of Life Index (DLQI) scores, which are highly correlated. Additionally, an improvement in psoriasis symptoms inventory score correlated with decreased PASI scores with SILIQ treatment.
In February 2017, the U.S. Food and Drug Administration (FDA) approved the Biologics License Application (BLA) for SILIQ, a novel human monoclonal antibody that binds to the interleukin-17 (IL-17) receptor A and inhibits inflammatory signaling by preventing the binding of several types of IL-17 to the receptor. By blocking IL-17 from activating the receptor, SILIQ prevents the body from receiving signals that may lead to inflammation. The IL-17 pathway plays a central role in inducing and promoting inflammatory disease processes.
In August 2015, Valeant entered into a collaboration agreement with AstraZeneca (AZN.LN, NYSE: AZN, AZN:SSE) granting Valeant an exclusive license to develop and commercialize SILIQ globally, except in Japan and certain other Asian countries where rights are held by Kyowa Hakko Kirin Co., Ltd. In July 2016, AstraZeneca and Valeant amended Valeant's license for brodalumab to terminate Valeant's right to develop and commercialize brodalumab in Europe. LEO Pharma currently holds exclusive rights to develop and commercialize brodalumab in Europe, and Valeant holds the license to develop and commercialize SILIQ in the U.S and other territories, other than Japan and certain other Asian countries.
