Novartis presents new data showing that the majority of patients are able to maintain clear or almost clear skin with Cosentyx across 3 years
In this extension study, 320 patients received Cosentyx in a fixed dosing schedule for three years. 69% achieved clear or almost clear skin (PASI 90) at year one. This response was extremely well maintained after three years with 64% of patients continuing to have a PASI 90 response. In addition, 43% of patients maintained completely clear skin (PASI 100) at year three (from 44% at year one). 83% achieved the standard treatment goal of PASI 75 skin clearance at three years.
"Psoriasis patients want therapies that maintain high levels of skin clearance over the long-term given the impact of the disease on their physical and psychological wellbeing," said Vasant Narasimhan, Global Head of Development, Novartis Pharmaceuticals. "In these new data from our longest Phase III trial to date with Cosentyx, we are pleased to show patients were able to maintain clear or almost clear skin for up to three years."
The PASI score assesses the reduction from baseline in the redness, scaling and thickness of psoriatic plaques and to what extent it affects each area of the body. PASI 75 has historically been considered the goal for psoriasis treatment. However, with newer treatments with increased efficacy, there is now a focus on PASI 90 (clear or almost clear skin) and PASI 100 (clear skin) as the ultimate goal for treatment, as recommended by clinical guidelines and regulatory authorities.
In this study, Cosentyx had a favorable safety profile consistent with that observed in previous Phase III studies.
About the A2304E1 Extension Study (Cosentyx Extension Study to SCULPTURE and STATURE studies)
A2304E1 is a multicenter, double-blind and open-label, four-year extension to the pivotal Phase III SCULPTURE and STATURE studies. In SCULPTURE 642 patients who completed 52 weeks of treatment continued into the extension. During the core study, PASI 75 responders at Week 12 were randomized to double-blind maintenance treatment of subcutaneous secukinumab 300 mg or 150 mg, administered either at a four-week fixed-interval (FI) regimen (320 patients) or in a retreatment-as-needed (RAN) regimen (322 patients). At entry into the extension, patients continued with the same blinded maintenance treatment regimen and dose that they had received in the SCULPTURE core study.
The primary objective of the extension study was to assess the long-term safety and tolerability of Cosentyx in patients with moderate-to-severe chronic plaque psoriasis. The secondary objective was to evaluate long-term efficacy of 300 mg and 150 mg Cosentyx administered in retreatment-as-needed versus fixed-interval regimens in patients who were PASI 75 responders at Week 12. Efficacy measures included proportion of patients achieving PASI 75, PASI 90 and PASI 100 as well as IGA mod 2011 0/1 responses.
Psoriasis affects up to 3% of the world's population, or more than 125 million people. This common and distressing condition is not simply a cosmetic problem, even people with very mild symptoms are affected every day. According to an analysis of surveys conducted on 5,600 patients by the National Psoriasis Foundation (NPF) between 2004 and 2011, 52% of patients with mild, moderate and severe psoriasis were dissatisfied with their disease management. Of the patients surveyed, some were receiving no treatment (9.4-49.2%) or were undertreated.
About Cosentyx (secukinumab) and interleukin-17A (IL-17A)
Cosentyx is a human monoclonal antibody that selectively neutralizes circulating interleukin-17A (IL-17A). IL-17A is found in high concentrations in skin affected by psoriasis and is a preferred target for investigational therapies. Cosentyx works by inhibiting the action of IL-17A, a protein found in high concentrations in skin affected by the disease.
In January 2015, Cosentyx (secukinumab) (at a recommended dose of 300 mg in the EU/US) became the first IL-17A inhibitor approved in Europe and the US. In Europe, Cosentyx is the only first-line biologic approved for the systemic treatment of moderate-to-severe plaque psoriasis in adult patients. In the US, Cosentyx is approved as a treatment for moderate-to-severe plaque psoriasis in adult patients who are candidates for systemic therapy or phototherapy (light therapy). In addition to the EU and the US, Cosentyx has been approved in Switzerland, Australia, Canada and a number of other countries for the treatment of moderate-to-severe plaque psoriasis and in Japan for the treatment of moderate-to-severe plaque psoriasis and psoriatic arthritis (PsA). More than 9,600 patients have been treated with Cosentyx in clinical trials across multiple indications, and over 9,000 patients have been treated in the post-marketing setting.
