ABBV-382

The main objectives of this study are to evaluate the safety, tolerability, pharmacokinetics, and immunogenicity of single subcutaneous (SC) and intravenous (IV) doses of ABBV-382 in healthy adult Chinese volunteers.

Crohn's disease (CD) is a long-lasting disease that causes severe inflammation (redness, swelling), in the digestive tract, most frequently affecting the bowels. It can cause many different symptoms including belly pain, diarrhea, tiredness, and weight loss. Treatments are available but do not work the same for all patients or may stop working over time. This study will evaluate the effectiveness and adverse events of targeted therapies (TaTs) for adult participants with moderate to severe CD.
The medicines assessed in this study are risankizumab, ABBV-382 and lutikizumab. When participants join the study, they will be randomized into available study treatment groups. Adult participants with CD will be enrolled. Around 500 participants will be enrolled in the study at approximately 300 sites worldwide.
Risankizumab and ABBV-382 are given as an injection under the skin or as an infusion into the vein. Lutikizumab is given as an injection under the skin. Each group includes a 12-week induction period, a 12-week maintenance period, and an optional long-term extension period where medication will be given after the maintenance period.
There may be higher treatment burden for participants in this trial compared to their standard of care treatment without participating in this study. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, endoscopies, checking for side effects and completing questionnaires and a daily diary.
