BALLERUP, Denmark, July 20, 2017 /PRNewswire/ --
LEO Pharma today announced that the European Commission has granted marketing authorisation for Kyntheum(R) (brodalumab), a new biologic for the treatment of moderate-to-severe plaque psoriasis in adults within the European Union who are candidates for systemic therapy.[1] Kyntheum(R) is the first and only biologic that selectively targets the IL-17 receptor subunit A.[2],[3]

Psoriasis is a common, chronic, immune-mediated, inflammatory disease[4] affecting an estimated 125 million people worldwide,[5] including nearly 14 million Europeans.[6] It primarily affects the skin, but carries with it a substantial social and psychological burden, even when a relatively small proportion of body surface is affected.[4]
Kyntheum(R) is different from existing therapies. By specifically binding to the receptor on skin cells rather than targeting free floating inflammatory mediators, brodalumab blocks the biological activity of several pro-inflammatory IL-17 cytokines involved in psoriasis plaque formation.[2],[7],[8]
"Lasting skin clearance is our ultimate treatment goal for psoriasis patients, as it has such a significant impact on an individual's wider wellbeing, along with their physical health. Experiencing clear skin brings a huge benefit to patients. Results from the AMAGINE trials show that Kyntheum(R) has the potential to virtually clear psoriasis in almost 80% of patients, often within just three months[*], establishing its approval as a major advancement within the field of psoriasis" commented Professor Dr. Ulrich Mrowietz, Psoriasis Centre, University Medical Centre, Schleswig-Holstein, Germany.
The AMAGINE trials - AMAGINE-1-3 - involved 4,373 patients with moderate-to-severe psoriasis,[9],[10] the largest study population in the development program of any new biologic treatment in psoriasis to date.[11],[12],[13],[14],[15],[16],[17] All three trials evaluated the efficacy and safety of different doses of Kyntheum(R) compared to placebo[9],[10] and AMAGINE-2 and -3 also compared Kyntheum(R) to ustekinumab.[9] Kyntheum (R) was well tolerated in all trials with an acceptable safety profile.[18] Although cases of suicidal ideation and behaviour were reported, no causal association between treatment with Kyntheum(R) and increased risk of suicidal ideation and behaviour has been established.[19] Its launch in Europe will be supported by post-marketing pharmacovigilance activities to capture and follow up on any reports of safety events.
Gitte Pugholm Aabo, President and CEO of LEO Pharma, said: "Those most affected by psoriasis often feel controlled by their condition, the stigma it brings, and the diverse complications associated with it. We hope that the EU approval of Kyntheum(R) will help many more people to regain control, and live lives unrestricted by psoriasis, while our role is to support them throughout their journey to clear skin."
Brodalumab is currently approved in the U.S. and Japan for adult patients with moderate-to-severe plaque psoriasis. In Japan, it is also approved for psoriasis vulgaris, psoriatic arthritis, pustular psoriasis and psoriatic erythroderma.
* 76-79% of patients achieved clear or almost clear skin (sPGA scores of 0 or 1) after 3 months of treatment with Kyntheum

NOTES TO EDITORS
About Kyntheum(R)
Kyntheum(R)(brodalumab) is the only fully human monoclonal antibody that selectively targets the IL-17 receptor subunit A.[2],[3] By binding to the receptor with high affinity, Kyntheum(R) effectively blocks the biological activity of several pro-inflammatory IL-17 cytokines, which are important in psoriasis.[3],[20]
The psoriasis clinical studies programme for Kyntheum(R) consisted of three clinical trials; AMAGINE-1 (n=661), AMAGINE-2 (n=1831) and AMAGINE-3 (n=1881).[9],[10] Results showed Kyntheum(R) 210mg offered more patients complete skin clearance (PASI 100) at 12 weeks compared to patients treated with ustekinumab [AMAGINE-2: 44% (n=272) versus 22% (n=65), p<0.001; AMAGINE-3: 37% (n=229) versus 19% (n=58), p<0.001].[9]
In AMAGINE-1 83% of patients on Kyntheum(R) 210mg achieved PASI 75[*] compared to 3% of patients treated with placebo at 12 weeks [83.3% (n=185) versus 2.7% (n=6), p<0.001] and 76% of patients achieved sPGA[**] success versus 1% of patients treated with placebo [75.7% (n=168) versus 1.4% (n=3), p<0.001].[10]
In the AMAGINE trials more than half (53-56%) of patients on continuous Kyntheum(R) treatment achieved PASI 100 at week 52.[10],[21]
Patients also reported experiencing improved health-related quality of life after four weeks of treatment with Kyntheum(R).[22] After 12 weeks of treatment, seven in ten patients (72%, n=29/40, p<0.0001) reported psoriasis no longer impaired their health-related quality of life, (0/1 DLQI) compared with placebo (5%, n=2/37).[22]
Data from the three large randomised, controlled AMAGINE clinical trials, found Kyntheum(R) to be well tolerated, with an acceptable safety profile.[18] The most common adverse events were arthralgia (joint pain), nasopharyngitis (inflammation of the nose and pharynx), headache, and upper respiratory tract infection.[10]
In July 2016, LEO Pharma entered into a partnership agreement with AstraZeneca granting LEO Pharma exclusive licence to develop and commercialise Kyntheum(R) in Europe. Outside of Europe, Valeant Pharmaceuticals has global commercial rights for brodalumab except in Japan and certain other Asian countries, where the rights are held by Kyowa Hakko Kirin Co., Ltd.
* PASI 75 is defined greater than or equal to 75% improvement in Psoriasis Area and Severity Index score
** sPGA success is defined as patients who achieved a static Physician's Global Assessment 0 or 1
About psoriasis
Psoriasis is a common, chronic, immune-mediated, inflammatory disease that primarily involves the skin.[4] The most frequently reported symptoms include thickening and scaling of the skin, itching and erythema (superficial reddening of the skin, usually in patches). [4]
An estimated 125 million people worldwide live with psoriasis,[5] including nearly 14 million Europeans.[6]
Psoriasis can be a painful, disabling and stigmatising condition with substantial social and psychological impact on a person's life.[17] People with psoriasis, especially those with more severe symptoms, are also at increased risk of developing other serious associated conditions,[23] including heart disease[24],[25],[26] and metabolic diseases (a combination of diabetes, high blood pressure and obesity).[27] Mental health complications, such as depression and anxiety, are also more common in people with psoriasis.[28]
According to the World Health Organization, the burden of living with psoriasis is underestimated and it urges for action to fight stigma and improve treatment.[4]
