Brief summary

The primary objective of Study M16-009 was to investigate the safety of risankizumab in participants with moderate to severe chronic plaque psoriasis who were receiving long-term treatment. Additional study objectives were to further investigate the long-term efficacy, tolerability, pharmacokinetics, pharmacodynamics, and immunogenicity of risankizumab.

Detailed description

Participants who had successfully completed Study 1311.2 (NCT02054481; the lead-in study) and met the eligibility criteria for Study M16-009 (extension study) had the option to enter the extension study. Participants were allowed to have the End of Study Visit in the lead in study combined with the Week 0 Visit for the extension study. At the Week 12 visit, participants were assigned to treatment based on 90% improvement in Psoriasis Area and Severity Index (PASI90) Score: participants with ≥PASI90 Score at Week 12 continued to receive risankizumab 90 mg by subcutaneous (SC) injection; participants with \<PASI90 Score at Week 12 switched to risankizumab 180 mg by SC injection. Efficacy results are summarized by the 4 treatment groups from the lead-in study, which included the following: Participants who received risankizumab 18 mg in the lead-in study and risankizumab in the extension study (Risankizumab 18 mg/Risankizumab); participants who received risankizumab 90 mg in the lead-in study and risankizumab in the extension study (Risankizumab 90 mg/Risankizumab); participants who received risankizumab 180 mg in the lead-in study and risankizumab in the extension study (Risankizumab 180 mg/Risankizumab); and participants who received ustekinumab (Stelara) 45 or 90 mg in the lead-in study and risankizumab in the extension study (Ustekinumab/Risankizumab).

The investigator assessed the relationship of each event to the use of study drug as either probably related, possibly related, probably not related or not related. A serious adverse event (SAE) is an event that results in death, is life-threatening, requires or prolongs hospitalization, results in a congenital anomaly, persistent or significant disability/incapacity or is an important medical event that, based on medical judgment, may jeopardize the subject and may require medical or surgical intervention to prevent any of the outcomes listed above. Treatment-emergent events (TEAEs/TESAEs) are defined as any event with an onset after the first dose of risankizumab in this study. See the Adverse Event section for details.

Percentage of Participants Achieving 90% Improvement in Psoriasis Area and Severity Index (PASI90) Score at Week 48 in the Extended Dosing PeriodBaseline, Week 48Psoriasis Area and Severity Index (PASI) is a composite score based on the degree of effect on body surface area of psoriasis and the 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. PASI90 is defined as at least a 90% reduction in PASI score compared with the Baseline PASI score. Baseline PASI for this study is defined as the baseline PASI in the lead-in study. The percent reduction in score is calculated as (PASI score at Baseline - score at follow-up visit) / PASI score at Baseline \* 100.

Participant flow

Recruitment details

Analyses were performed using the intent-to-treat (ITT) population defined as all participants who received at least 1 dose of study drug. As predefined, the demographics, disposition and safety results were summarized for ITT population. Efficacy results were summarized by the 4 treatment groups from the lead-in study (Study 1311.2; NCT02054481).

Pre-assignment details

Participants completing lead-in study and met eligibility for this study were enrolled; demographic/disposition were not collected by dose level. Some participants in extension study had dose escalation due to lack of efficacy, predefined selected safety analysis were broken down by groups: participants remaining at 90mg and those receiving 180mg.

The sPGA is an assessment by the investigator of the overall disease severity at the time of evaluation. Erythema (E), induration (I), and desquamation (D) are scored on a 5-point scale ranging from 0 (none) to 4 (severe). The sPGA ranges from 0 to 4, and is calculated as Clear (0) = 0 for all three; Almost clear (1) = mean \>0, \<1.5; Mild (2) = mean ≥1.5, \<2.5; Moderate (3) = mean ≥2.5, \<3.5; and Severe (4) = mean ≥3.5. Baseline is defined as the last non-missing value on or before the date of the first dose of study drug in the lead-in study.

Time frame: Week 48
