The European Commission approves Almirall’s ILUMETRI® (tildrakizumab) for moderate-to-severe chronic plaque psoriasis

Almirall, S.A. announced today that the European Commission(EC)has approved ILUMETRI® (tildrakizumab),a humanized, high-affinity IL-23p19 monoclonal antibody, for the treatment of adult patients with moderate-to-severe chronic plaque psoriasis who are candidates for systemic therapy1. Roll out of ILUMETRI® (tildrakizumab) in Europe will start in the next few weeks. Germany will be the first country to launch the product.  

According to Peter Guenter, Almirall's CEO, “we are proud of the EC’s approval for ILUMETRI®, as it constitutes a new therapeutic option for European healthcare professionals and patients with moderate-to-severe chronic plaque psoriasis. ILUMETRI®is a safe, easy to administer, targeted IL-23p19 inhibitor that provides durable efficacy and long-term safety, this marks a very important milestone for Almirall in the medical dermatology area, specifically in the biological drugs market”.   

Tildrakizumab is a humanized high-affinity anti-IL-23p19 monoclonal antibody.1Due to its specific mechanism of action,itselectively blocks interleukin-23 (IL-23), an upstream inflammatory mediator cytokine, and acts by modifying the pathogenesis of the disease with limited impact on the rest of the immune system. Tildrakizumab constitutes a very significant step forward in the treatment of moderate-to-severe chronic plaque psoriasis, it is a drug with a high level of safety and efficacy that achieves a long-term control of the disease.3

ILUMETRI®(tildrakizumab) is administered by subcutaneous injection. Its convenient dosing regimen, every 3 months during maintenance, results in greater convenience and quality of life for patients, achieving a better control and improved treatment satisfaction1. With only 4 doses per year during maintenance, ILUMETRI®offers a convenient dosing regimen.3This low frequency of injections may also encourage adherence.3 

Its approval in Europe is based on reSURFACE 1 and 2positiveresults, presented for the first time in October 2016 at the 25thEuropean Academy of Dermatology and Venerology(EADV) Congress in Vienna (Austria). Both pivotal phase III clinical trials, which included over 1,800 patients from more than 200 clinical sites worldwide, showed ILUMETRI®has a high level of safety and efficacy. 

According to both studies data, an average of 63% of patients achieved 75% of skin clearance (Psoriasis Area Sensitivity Index or PASI 75) by week 12 and an average of 78% at week 28 after only three doses. Moreover, an average of 59% of patients achieved PASI 90 and an average of 30% reached PASI 100 at week 28. Over a year, more than 92% of patients who responded to ILUMETRI®within 28 weeks maintained a PASI 75 response.  

Moreover, the results of a pooled analysis through 3 years2from reSURFACE 1 and reSURFACE 2 phase III trials3show the consistent maintenance of efficacy and safety over three years of ILUMETRI®in patients with moderate-to-severe chronic plaque psoriasis who were responders at week 28. According to the data, PASI 75 responses were maintained with continued treatment with ILUMETRI®  in 9 out of 10 patients up to week 148.3More than 50% of patients reported that psoriasis no longer affected their lives after only 3 doses.1,3ILUMETRI®was well-tolerated with very low drug-related serious adverse events and discontinuation rates.

Almirall in-licensed tildrakizumab from Sun Pharmaceutical Industries Ltd. (Sun Pharma) in July 2016. The agreement is for development and commercialization of ILUMETRI®(tildrakizumab) in Europe.

Sun Pharma got approval for Tildrakizumab from the US FDA in March this year for the treatment of adults with moderate-to-severe plaque psoriasis who are candidates for systemic therapy or phototherapy. In July 2018, tildrakizumab received the CHMP positive opinion for its marketing in Europe.


ILUMETRI®is a humanized, anti-IL-23p19 monoclonal antibody designed to selectively block the cytokine IL-23. With this precise targeting, ILUMETRI®has the potential to help control the pathogenic cells responsible for the inflammatory process of psoriasis with limited impact on the rest of the immune system.

About Psoriasis

Psoriasis is a chronic immune disease that appears on the skin. It affects an estimated 7.8 million adults in Europe and approximately 125 million people worldwide.4It is a non-contagious disorder that accelerates the growth cycle of skin cells and results in thick scaly areas of skin. The most common form of psoriasis, called plaque psoriasis, appears as red, raised areas of skin covered with flaky white scales, which may be itchy and painful and can crack and bleed. Despite different treatment options existing, many people with plaque psoriasis continue to struggle with the ongoing, persistent nature of this chronic disease.
