Study to Evaluate the Effectiveness of Risankizumab in Participants With a Recent Diagnosis of Moderate Plaque Psoriasis in a Real-life Setting in Greece (REDEFINE)

February 2, 2026 updated by: AbbVie

A Non-interventional, Prospective Study to Evaluate the Effectiveness of Risankizumab in Patients With Recent Diagnosis of Moderate Plaque Psoriasis in a Real Life Setting in Greece- the REDEFINE Study

Psoriasis is a skin disorder wherein skin cells multiply faster than normal, making the skin itchy and look patchy and red. It is caused by an overactive immune system where the body attacks healthy tissue by mistake. The impact of Psoriasis on quality of life can be significant, especially in moderate-to-severe disease which affects approximately half of the participants with plaque Psoriasis. Participants with Psoriasis are marked by their disease physically, psychologically, and emotionally. In addition to the above, their disease exerts a negative effect on various dimensions of health-related quality of life such as daily activities and work productivity. This study is designed to provide information regarding the impact of risankizumab on short-term and long-term clinical parameters of Psoriasis as well as the patient-reported outcomes (PROs) in participants with a recent diagnosis (less than or equal to 24 months) of moderate Psoriasis who are naïve to advanced treatments.

Risankizumab is an approved drug for the treatment of Plaque Psoriasis. Approximately 250 participants with a recent diagnosis of moderate plaque psoriasis (defined as less than or equal to 24 months since the first diagnosis of moderate Psoriasis), and naïve to advanced treatments (biologics, apremilast, and deucravacitinib) will be enrolled at approximately 20 sites in Greece.

Participants will receive risankizumab as prescribed by their treating dermatologist in accordance with local authorization and independently from the study. Participants will be enrolled and observed for approximately two years.

There is expected to be no additional burden for participants in this trial. Study visits comprised of private practices and hospital clinics as per standard of care.

Group / Cohort
Participants Treated with Risankizumab
Participants with a recent diagnosis of moderate plaque PsO (defined as ≤24 months since the first diagnosis of moderate PsO), and naïve to advanced treatments (biologics, apremilast, and deucravacitinib) will receive risankizumab as prescribed by their physician according to local label.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Proportion of participants achieving Psoriasis Area and Severity Index (PASI) score less than or equal to 2
Time Frame: Baseline to Week 16
The Psoriasis Area and Severity Index (PASI) is a composite score based on the degree of effect on body surface area of psoriasis and extension of erythema (reddening), induration (thickness), desquamation (scaling) of the lesions and area affected as observed on the day of examination. The severity of each sign was assessed using a 5-point scale, where 0=no symptoms, 1=slight, 2=moderate, 3=marked, 4=very marked. The PASI score ranges from 0 to 72, where 0 indicates no psoriasis and 72 indicates very severe psoriasis.
Baseline to Week 16
Proportion of participants achieving a Dermatology Life Quality Index (DLQI) score of 0 or 1 (include only patients with DLQI score less than or equal to 2 at Baseline)
Time Frame: Baseline to Week 16
DLQI (Dermatology Life Quality Index) assesses symptoms and impacts of dermatologic diseases on quality of life. DLQI scores range from 0 (no effect) to 30 (very large effect), with a higher score indicating a more impaired quality of life.
Baseline to Week 16
