- Longer-term results from IMMhance showed 73 percent and 72 percent of patients treated with continuous SKYRIZI™ (risankizumab) experienced complete skin clearance (defined as sPGA 0 and PASI 100, respectively) at week 94, among patients who achieved sPGA 0/1 at week 28

NORTH CHICAGO, IL, USA I June 11, 2019 I AbbVie (NYSE: ABBV), a research-based global biopharmaceutical company, today announced new results showing a significant number of patients treated with SKYRIZI™ (risankizumab) experienced complete skin clearance at week 94.1 In the study, at week 28 patients who achieved a static Physician Global Assessment (sPGA) score of clear or almost clear (sPGA 0/1) were re-randomized to continue treatment with SKYRIZI or withdrawal.1 After 94 weeks of continuous treatment with SKYRIZI, 73 percent and 72 percent of these patients achieved a sPGA score of clear (sPGA 0) and a 100 percent improvement in the Psoriasis Area and Severity Index (PASI 100), respectively, compared to 2 percent of patients re-randomized to withdrawal (p<0.001).1 These two-year results (up to 104 weeks) from the Phase 3 IMMhance study, evaluating the efficacy and safety of SKYRIZI in adult patients with moderate to severe psoriasis, will be presented today at the 24th World Congress of Dermatology (WCD) in Milan.
"Results show that SKYRIZI has the potential to provide long-term relief from the signs and symptoms of psoriasis," said Marek Honczarenko, M.D., Ph. D., vice president, immunology development, AbbVie. "Our studies demonstrated that SKYRIZI can not only offer complete skin clearance at two years of treatment for the majority of patients, but re-treatment with SKYRIZI following a relapse can help patients regain skin clearance in just 16 weeks. We are pleased to add positive long-term data to the growing body of evidence supporting the efficacy and safety profile of SKYRIZI for adult patients with moderate to severe psoriasis."
SKYRIZI is part of a collaboration between Boehringer Ingelheim and AbbVie, with AbbVie leading development and commercialization globally.
There were two phases in the IMMhance study.1 Results from the first phase were previously reported and showed that after 16 weeks of treatment, SKYRIZI (n=407) met the co-primary endpoints of PASI 90 and sPGA 0/1 versus placebo (n=100) (p<0.001).1 The second phase (week 28 through week 104) evaluated the efficacy and safety of continuous therapy with SKYRIZI versus randomized withdrawal, as well as re-treatment.1 Patients who achieved sPGA 0/1 at week 28 with SKYRIZI were re-randomized to continue SKYRIZI (n=111) every 12 weeks or to withdrawal (n=225).1 The primary endpoint from the second phase of the study, sPGA 0/1, was also met at one year (52 weeks) (p<0.001).1
For those re-randomized to continue SKYRIZI, the last dose was given at week 88.1 Between one year (week 52) and week 94, the proportion of these patients who achieved complete skin clearance continued to increase.1 sPGA 0 and PASI 100 responses increased from 65 percent and 64 percent at week 52 to 73 percent and 72 percent at week 94, respectively (p<0.001).1 At two years, 81 percent and 78 percent of patients treated with continuous SKYRIZI maintained clear or almost clear skin (sPGA 0/1 or PASI 90) compared to 7 percent and 4 percent re-randomized to withdrawal, respectively (p<0.001).1
Among patients re-randomized to withdrawal who experienced a loss of response (defined as a sPGA score of moderate to severe [≥3]) on or after week 32 (n=153), 84 percent regained clear or almost clear skin (sPGA 0/1) after 16 weeks of re-treatment with SKYRIZI.1
"In the IMMhance study, SKYRIZI provided an increasing number of patients with complete skin clearance up to 94 weeks," said Melinda Gooderham, M.D., dermatologist and medical director at the SKiN Centre for Dermatology in Peterborough, Ontario and a study investigator. "SKYRIZI not only offers relief from the signs and symptoms of psoriasis following a withdrawal from medication, but the study further demonstrates the significant rates of complete skin clearance that can be achieved with continuous treatment at the recommended dose. These data underscore the lasting impact this new treatment option could provide for people living with psoriasis."
No new safety findings were observed in patients who continued with SKYRIZI for two years compared with those who withdrew to placebo at week 28.1 Rates of treatment-emergent adverse events were similar to placebo at week 16 and remained stable over time in patients treated with SKYRIZI.1
About the Phase 3 IMMhance Study1
The IMMhance study is an ongoing Phase 3, multicenter, randomized, double-blind, placebo-controlled study designed to evaluate the safety and efficacy of SKYRIZI compared to placebo in adult patients with moderate to severe plaque psoriasis. In the first phase, patients were randomized 4:1 to SKYRIZI (n=407)(150 mg), given as a subcutaneous injection at baseline, 4 weeks later and every 12 weeks thereafter, or placebo (n=100). In the second phase of this study (week 28 through week 104), patients originally randomized to SKYRIZI who achieved sPGA 0/1 at week 28 were re-randomized to SKYRIZI (maintenance, n=111) or placebo (withdrawal, n=225). Safety was assessed in all patients. Patients received their last dose of SKYRIZI at week 88 and follow up was conducted until week 104.
This Phase 3 study was conducted in cooperation between AbbVie and Boehringer Ingelheim. More information on this trial can be found at www.clinicaltrials.gov (NCT02672852).
