Summary

The primary objective of the study was to investigate long-term safety of risankizumab (BI 655066/ABBV-066) in participants with moderately to severely active Crohn's disease who showed a clinical response or remission on previous treatment with risankizumab in Study NCT02031276 (BI trial 1311.6/ AbbVie M15-993) and were now receiving long-term treatment. Additional objectives of this study were to further investigate long-term efficacy, tolerability, pharmacokinetics, pharmacodynamics and immunogenicity of risankizumab.

Criteria

Inclusion Criteria:

1. Completion of period 2 in 1311.6 with a clinical response (drop in Crohn's Disease Activity Index (CDAI) from baseline by ≥100) but no remission (CDAI < 150) at Visit E1; or

2. Completion of period 3 in 1311.6 with a clinical response (drop in CDAI from baseline by ≥100) and/or remission (CDAI < 150) at Visit E5; or

3. Completion of period 2 or 3 in 1311.6 per protocol with a clinical response or remission before initiation of 1311.20 can roll-over either directly if that response/remission is maintained or through an open-label i.v. re-induction phase if they have lost their previous response/remission.

• Female participants:

2. Surgically sterilized female participants with documentation of prior hysterectomy, tubal ligation or complete bilateral oophorectomy, or

3. Postmenopausal women with postmenopausal is defined as permanent cessation >/=1 year of previously occurring menses, and

• Participants who could not tolerate risankizumab (BI 655066/ ABBV-066) treatment for tolerability or safety reasons in the preceding trial

• Are pregnant, nursing, or planning pregnancy while enrolled in the study, or within 20 weeks after receiving the last dose of study medication.

• Participants must agree not to receive a live virus or bacterial or Bacille Calmette-Guérin vaccination during the study or up to 12 months after the last administration of study drug.
