New data presented at the American Academy of Dermatology show LEO Pharma’s Kyntheum® (brodalumab) improves psoriasis on the nail

Posted on: 19 Feb 18


LEO Pharma today announced new data demonstrating long-term improvements in psoriasis on the nail with Kyntheum® (brodalumab) when compared to placebo or ustekinumab.1 Psoriasis on the nail, which is challenging to treat,2 affects approximately half of the estimated 125 million people living with psoriasis worldwide.2,3 The data were presented at the 76th annual American Academy of Dermatology (AAD) meeting in San Diego, California, US.

Psoriasis is a common, chronic, immune-mediated, inflammatory disease that primarily involves the skin, but also impacts emotional, psychological and physical health.4 The heavy and far-reaching burden of the disease can be disabling and stigmatising with a substantial negative impact on those affected and their families.4 Due to the visible nature of the condition, psoriasis on the nail can be particularly upsetting for patients.4 In moderate to severe cases, psoriasis on the nail can be painful and restrict movement in the fingers and toes.5

The efficacy of Kyntheum® in psoriasis on the nail (as measured by NAPSI,* the nail psoriasis severity index) was assessed based on the outcomes of two randomised Phase III clinical studies, AMAGINE-2 and -3. Results showed that in patients with psoriasis on the nail, Kyntheum® decreased the NAPSI score in the most affected nail at week 52 and was associated with a lower NAPSI score than ustekinumab and placebo.1 Patients continuously receiving Kyntheum® 210 mg changed from a mean NAPSI score of 9.6 at baseline to 1.6 at week 52; patients receiving ustekinumab changed from a mean NAPSI score of 9.9 at baseline to 2.4 at week 52. Across all patients, the profile of treatment-emergent adverse events was similar in those taking Kyntheum® 210 mg and ustekinumab.1

“Although psoriasis on the nail can be challenging to treat, these data add to the growing body of evidence showing biologic medications to be highly efficacious treatments,” said Kim Domela Kjoeller, Executive Vice President, Global Research & Development, LEO Pharma. “These, and other data presented at AAD, reinforce the safety and efficacy of Kyntheum ® and solidify its positioning as a leading biologic treatment option for people living with psoriasis.”

Additional pooled data evaluating the long-term safety of Kyntheum® in the Phase III AMAGINE-1,-2,-3 clinical trials were also presented at AAD.6 After two years, the safety profile of Kyntheum® was similar to that observed during the first year of exposure with no new safety signals.6 Of the 3,587 patients evaluated at year two, the most common treatment-emergent adverse events were arthralgia (joint pain) (n=196), headache (n=155) and candida infections (n=111).6

Kyntheum® is indicated for the treatment of moderate to severe plaque psoriasis in adult patients who are candidates for systemic therapy.7 Itis the first and only biologic treatment for psoriasis that targets the receptors through which the interleukin (IL)-17 cytokines – a family of proteins involved in immune responses– need to signal to cause the inflammation associated with psoriasis. This mechanism of action is different to all other anti-IL-17 psoriasis biologics currently available.8,9 Other anti-IL-17 biologics target the IL-17A cytokine alone.7,9,10,11

* The Nail Psoriasis Severity Index (NAPSI) is a tool used to assess nail involvement in patients with psoriasis.
