Novartis' Cosentyx receives European nod to treat ankylosing spondylitis & psoriatic arthritis

The European Commission (EC) has approved Novartis' Cosentyx (secukinumab) for the treatment of people living with ankylosing spondylitis (AS) and psoriatic arthritis (PsA). For AS, this is the first new treatment advance in 16 years since the development of the current standard of care, anti-tumour necrosis factor (anti-TNF) therapy.

Cosentyx is the first in a new class of medicines called interleukin-17A (IL-17A) inhibitors to be made available in Europe for AS and PsA. These approvals follow on from the earlier EC approval of Cosentyx for the first-line treatment of patients with moderate-to-severe plaque psoriasis.

AS and PsA are common inflammatory joint conditions affecting approximately five million people in Europe, yet they remain significantly under-diagnosed and under-treated. If not treated effectively, they can lead to irreversible damage to the spine and joints, causing life-long pain and disability. New treatments are urgently needed for both conditions as many patients do not respond well to existing treatments, with up to 40 per cent not responding sufficiently to anti-TNFs.

"The strong treatment benefits seen in our studies suggest that Cosentyx may give patients the chance to stop the disease from progressing, preventing living with pain and disability," said David Epstein, division head, Novartis Pharmaceuticals.

"These approvals mean that people living with ankylosing spondylitis and psoriatic arthritis across Europe can now start to benefit from this next generation biologic that has the potential to become a new standard of care for these common but under-treated inflammatory conditions."

Recent studies have shown that Cosentyx provided a significant reduction in the signs and symptoms of AS or PsA as early as week 1-3, which were sustained over two years. Up to 80 per cent of AS patients treated with Cosentyx showed no progression in spinal damage as measured by x-ray over two years. In PsA, 84 per cent of patients showed no progression of joint damage on x-ray over two years.

More than 9,600 patients have been treated with Cosentyx in clinical trials across multiple indications, and over 12,500 patients have been treated in the post-marketing setting. The safety profile of Cosentyx was shown to be consistent with that seen in clinical trials across multiple indications.

Cosentyx is now licensed to treat active AS in adults who have responded inadequately to conventional therapy, such as non-steroidal anti-inflammatory drugs, and for the treatment of active PsA in adult patients alone or in combination with methotrexate when the response to previous disease modifying anti-rheumatic drug therapy has been inadequate.

For patients with AS and PsA, the approved dose is Cosentyx 150 mg by subcutaneous injection (under the skin) with initial dosing at weeks 0, 1, 2 and 3, followed by monthly maintenance dosing starting at week 4. For patients with PsA who also have moderate-to-severe plaque psoriasis, or who are anti-TNF inadequate responders, the recommended dose is Cosentyx 300 mg.

Pivotal phase III studies in the Cosentyx clinical trial programme, that provided key data for the submission, were MEASURE 1 and MEASURE 2 in AS, and FUTURE 1 and FUTURE 2 in PsA. These are ongoing multi-center, randomized, placebo-controlled studies that have been designed to evaluate the efficacy and safety of Cosentyx in AS and PsA.

AS is a painful, progressively debilitating condition caused by inflammation of the spine. Up to 70 per cent of patients with severe AS develop spinal fusion (where new bone growth immobilizes the spine) over 10 to 15 years, which significantly reduces mobility and quality of life. AS occurs in approximately 1.78 million people in Europe and typically affects young men and women aged 25 or older.

PsA is an inflammatory condition of the joints and is often associated with a scaly skin condition called psoriasis. It occurs in approximately 3.1 million people in Europe. As many as 30 per cent of people with psoriasis have PsA and up 25 per cent of people with psoriasis may have undiagnosed PsA.

Cosentyx is a human monoclonal antibody that selectively neutralizes circulating IL-17A. Cosentyx is the first IL-17A inhibitor with positive phase III results for the treatment of PsA and AS. Research suggests that IL-17A may play an important role in driving the body's immune response in psoriasis, PsA and AS.

In total, 50 countries have approved Cosentyx for the treatment of moderate-to-severe plaque psoriasis which includes the European Union countries, Switzerland, Australia, the US and Canada. 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 Japan, Cosentyx is approved for the treatment of moderate-to-severe plaque psoriasis and also for the treatment of PsA. In Ecuador, Cosentyx is approved for the treatment of PsA and AS.
