BARCELONA, Spain. July 7, 2023 – Almirall, S.A. (ALM), a global biopharmaceutical company focused on medical dermatology, today announced that Ilumetri® (tildrakizumab) significantly improved wellbeing in patients with moderate-to-severe plaque psoriasis achieving a wellbeing status similar to the general populationi after 16 weeks, which was maintained up to week 28 i . These first results of the POSITIVE study were presented in a poster at the 25th World Congress of Dermatology, held in Singapore from 3-7 July.

The preliminary analysis also showed that tildrakizumab significantly improved skin symptoms and patients’ health-related quality of life (HRQoL), with high rates of treatment satisfaction in patients with moderate-to-severe plaque psoriasis after 28 weeks in a real-world setting,iv with no new safety signals and a reassuring safety profile consistent with randomized clinical trials (RCT).i,ii The results also demonstrated for the first time that the wellbeing level at baseline of patients with moderate-to-severe plaque psoriasis was comparable to the wellbeing level found in other diseasesiii such as breast cancer.iv

The POSITIVE study is the first clinical study in dermatology to assess patients’ wellbeing as a primary endpoint using the WHO-5. The 5item World Health Organization Wellbeing Index is a widely used questionnaire that assesses health-related subjective psychological wellbeing in a variety of chronic diseases. In addition to evaluating the severity of psoriasisv, there is a need for a holistic, person-centred approach to the assessment of wellbeing that has never before been measured in a robust prospective study. The results of this study could potentially be added to the available psoriasis evaluation methods and provide dermatologists with new tools to improve their patients’ wellbeing by enhancing patient-clinician relationships.

Psoriasis affects an estimated 60 million people worldwidevi, and the severity of psoriasis is profound, involving both a physical and psychological burdenvii. Almost 77% of patients believe that psoriasis negatively affects their normal daily activities (personal, social, and work lifeviii) and wellbeing.ix In addition, psoriasis can significantly affect the general wellbeing of their familiesx and physicians' satisfaction.xi

"We are thrilled with the promising results of the POSITIVE study, as they underline the importance of incorporating wellbeing into clinical trials. Having a holistic and patient-centered approach allows for more data on the impact of treatments on people living with psoriatic disease and therefore improves health and quality of life",  said Frida Dunger Johnsson , IFPA Executive Director.

"At Almirall, we have long strived to improve patient quality of life by taking a holistic approach to skin diseases that captures the full impact of these conditions. The POSITIVE study marks a ground-breaking milestone in dermatology research and its preliminary findings reveal a notable enhancement in the wellbeing of individuals with psoriasis who were treated with tildrakizumab. These initial results reinforce our conviction that we are on the right track in fulfilling our commitment to offer healthcare professionals and patients innovative solutions that effectively address their unmet needs”, stated Volker Koscielny , Chief Medical Officer at Almirall.

About the POSITIVE Study

The POSITIVE study uses the 5item World Health Organization Wellbeing Index, WHO-5, a widely used questionnaire that assesses health-related subjective psychological wellbeing in a variety of chronic diseases. Following the holistic approach, the POSITIVE study will also use innovative secondary endpoints, the FamilyPso questionnaire to evaluate the impact of the disease on the family environment, and on Physician wellbeing, using the Physician’s Satisfaction Score.

This ongoing non-interventional, prospective, observational, real-world evidence study has enrolled approximately 780 adults with moderate-to-severe psoriasis at multiple sites in Europe, including Austria, Belgium, France, Germany, Italy, Spain, Switzerland, The Netherlands, and the United Kingdom. The study will follow these patients for 24 months in their treatment with tildrakizumab.
