LEO Pharma Receives EU Marketing Authorization for Kyntheum to Treat Plaque Psoriasis


The European Commission has granted marketing authorisation for LEO Pharma's Kyntheum (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. Kyntheum selectively targets the IL-17 receptor subunit A. 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.

"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 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, the largest study population in the development program of any new biologic treatment in psoriasis to date. All three trials evaluated the efficacy and safety of different doses of Kyntheum compared to placebo, and AMAGINE-2 and -3 also compared Kyntheum to ustekinumab. Kyntheum was well tolerated in all trials with an acceptable safety profile. Although cases of suicidal ideation and behaviour were reported, no causal association between treatment with Kyntheum and increased risk of suicidal ideation and behaviour has been established. Its launch in Europe will be supported by post-marketing pharmacovigilance activities to capture and follow up on any reports of safety events.

Brodalumab is currently approved in the US 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.
