SKYRIZI™ ▼(risankizumab) Granted EU Marketing Authorisation for the Treatment of Moderate to Severe Plaque Psoriasis in Adults

Press release   •   Apr 30, 2019 13:14 BST

– Authorisation based on results from clinical studies showing high rates of skin clearance at 16 weeks; this clearance was also observed at one year with every 12-week maintenance dosing1-4

– Risankizumab, a humanized immunoglobulin G1 (IgG1) monoclonal antibody designed to selectively inhibit IL-23 by binding to its p19 subunit, offers moderate to severe psoriasis patients a new therapeutic option5

– Psoriasis is a chronic condition affecting 125 million people worldwide and many patients still do not reach treatment goals or lose treatment response over time6-8

MAIDENHEAD, UK, 30 April, 2019 – AbbVie (NYSE: ABBV), a research-based global biopharmaceutical company, today announced that the European Commission (EC) has granted a Marketing Authorisation to SKYRIZI™ ▼(risankizumab) for the treatment of moderate to severe plaque psoriasis in adult patients who are candidates for systemic therapy. The recommended dose of risankizumab is 150mg (two 75 mg injections) administered by two subcutaneous injections every 12 weeks following two initiation doses at week 0 and week 4. In clinical studies, risankizumab demonstrated high rates of skin clearance at 16 weeks and this clearance was also maintained through to one year (52 weeks).1-4

"This authorisation is an important step forward in providing people living with moderate to severe psoriasis across the UK with a new treatment option,” said Alice Butler, UK Medical Director, AbbVie. “We know that patients who achieve and then maintain high skin clearance of PASI90 or complete skin clearance of PASI100 have significantly better health related quality of life outcomes than those with lower levels of skin clearance of PASI75-89.12”

Professor Christopher Griffiths, University of Manchester, said: “The introduction of risankizumab is good news for those people in the UK who have moderate to severe psoriasis. The options now available for dermatologists treating this severity of psoriasis have never been better. Indeed, we are in the enviable position of being able to offer the majority of such patients complete or almost complete clearance of the signs and symptoms of psoriasis, at least in the short term. This progress could not have been achieved without a detailed understanding of the immune drivers of psoriasis and the identification of new targets for drugs such as risankizumab.”

Helen McAteer, Chief Executive of the Psoriasis Association, said: “We are delighted that risankizumab has received licensed authorisation following the successful Phase III trials. Patients in touch with the Psoriasis Association have reported a preference for every 12 week injections over those dosed more frequently and the long-term PASI90 and PASI100 clearance data will be welcomed by people living with moderate–severe psoriasis.”

Risankizumab received EC Marketing Authorisation based on results from four pivotal Phase 3 studies, UltIMMa-1, UltIMMa-2, IMMvent and IMMhance evaluating more than 2,000 patients with moderate to severe plaque psoriasis.1-4 Across all four studies, the co-primary endpoints were at least a 90 percent improvement in the Psoriasis Area and Severity Index (PASI 90) and a static Physician Global Assessment (sPGA) score of clear or almost clear (sPGA 0/1) at week 16.1-4 Risankizumab is part of a collaboration between Boehringer Ingelheim and AbbVie, with AbbVie leading development and commercialisation globally.

Highlights from the pivotal Phase 3 programme

  • In the UltIMMa-1 (n=506) and UltIMMa-2 studies (n=491), risankizumab met the co-primary endpoints of sPGA 0/1 and PASI 90 at week 16 vs placebo (p<0.0001).1,4 After 16 weeks of treatment, 88 percent (UltIMMa-1) and 84 percent (UltIMMa-2) of risankizumab patients (UltIMMa-1 n=304; and UltIMMa-2 n=294) achieved sPGA 0/1 and 75 percent of patients receiving risankizumab in both studies achieved PASI 90.1,4
  • An integrated analysis of patients who received risankizumab in the UltIMMa-1 and UltIMMa-2 studies (n=598) showed that of patients who achieved PASI 90 with risankizumab at week 16, 88 percent of these patients maintained PASI 90 with risankizumab through to one year (52 weeks) (p=0.0009).1
  • Risankizumab demonstrated superiority versus adalimumab in the IMMvent study (n=605), with 72 percent of rizankizumab patient (n=301) achieving PASI 90 compared to 47 percent of patients treated with adalimumab (n=304) at week 16 (p<0.001).2,4 Patients achieving PASI 50-<90 after 16 weeks of adalimumab treatment were re-randomised at week 16, following this 66 percent of patients who started on adalimumab and switched to risankizumab (n=53) achieved PASI 90, compared to 21 percent who continued on adalimumab (n=56) at week 44 (p<0.001).2,4 The co-primary endpoints of sPGA 0/1 and PASI 90 at week 16 were met (p<0.001).2,4
  • Results from IMMhance (n=507) showed that, among people receiving risankizumab (n=407) who achieved clear or almost clear skin (sPGA 0/1) response at week 28 and were re-randomised to continue risankizumab (n=111), 87 percent maintained this response at week 52 compared to 61 percent re-randomized to withdraw (n=225).9 The co-primary endpoints of sPGA 0/1 at week 16 and week 52 were met (p<0.001).3,4
  • Risankizumab was also reported to improve health-related quality of life in Phase 3 studies. In UltIMMa-1 and UltIMMa-2, significantly more patients treated with risankizumab self-reported a Dermatology Life Quality Index (DLQI) score of 0 or 1 (75 percent in UltIMMa-1 and 71 percent in UltIMMa-2) compared with ustekinumab (47 percent in UltIMMa-1 and 44 percent in UltIMMa-2) at one year (p<0.0001).1,4 DLQI is a measure of a patient's health-related quality of life, ranging from 0 to 30, with lower scores indicating the disease has less impact on life quality.10

    The most frequently reported adverse reactions were upper respiratory infections, which occurred in 13 percent of patients.4 Common adverse reactions (frequency defined as greater than or equal to 1/100 events to less than 1/10) included tinea infections, headache, pruritus, fatigue and injection site reactions.4

    About risankizumab in the UK

    Risankizumab is indicated for the treatment of moderate to severe plaque psoriasis in adults who are candidates for systemic therapy.

    Important EU Safety Information4

    Risankizumab is contraindicated in patients with hypersensitivity to the active substance or to any of the excipients. It is also contraindicated in patients with clinically important active infections (e.g. tuberculosis). Risankizumab may increase the risk of infection. In patients with a chronic infection, a history of recurrent infection, or known risk factors for infection, risankizumab should be used with caution. Treatment with risankizumab should not be initiated in patients with any clinically important active infection until the infection resolves or is adequately treated.

    Prior to initiating treatment with risankizumab, patients should be evaluated for tuberculosis (TB) infection. Patients receiving risankizumab should be monitored for signs and symptoms of active TB. Anti-TB therapy should be considered prior to initiating risankizumab in patients with a past history of latent or active TB in whom an adequate course of treatment cannot be confirmed.

    Prior to initiating therapy with risankizumab, completion of all appropriate immunizations should be considered according to current immunization guidelines. If a patient has received live vaccination (viral or bacterial), it is recommended to wait at least 4 weeks prior to starting treatment with risankizumab. Patients treated with risankizumab should not receive live vaccines during treatment and for at least 21 weeks after treatment.

    ▼Adverse events should be reported. Reporting forms and information can be found at Adverse events should also be reported to AbbVie on With biological medicines, healthcare professionals should report adverse reactions by brand name and batch number.

    About adalimumab in the UK

    Adalimumab is indicated for the treatment of moderate to severe chronic plaque psoriasis in adult patients who are candidates for systemic therapy.

    Important EU Safety Information11

    Adalimumab is contraindicated in patients with active tuberculosis or other severe infections such as sepsis, and opportunistic infections and in patients with moderate to severe heart failure (NYHA class III/IV). It is also contraindicated in patients hypersensitive to the active substance or to any of the excipients; serious allergic reactions including anaphylaxis have been reported. The use of adalimumab increases the risk of developing serious infections, including hepatitis B reactivation, which may, in rare cases, be life-threatening. Rare cases of lymphoma and leukemia have been reported in patients treated with adalimumab. On rare occasions, a severe type of cancer called hepatosplenic T-cell lymphoma has been observed and often results in death. A risk for the development of malignancies in patients treated with TNF-antagonists cannot be excluded. Rare cases of pancytopenia, aplastic anaemia, demyelinating disease, lupus, lupus-related conditions and Stevens-Johnson syndrome have been reported in patients treated with adalimumab. The most frequently reported adverse events across all indications included respiratory infections, injection site reactions, headache and musculoskeletal pain.
