The objective of this study is to assess the safety, tolerability, pharmacokinetics and immunogenicity of either single ascending intravenous (IV) doses of ABBV-243 or single ascending subcutaneous (SC) doses of ABBV-243 in healthy adult participants (Part 1), and a single intravenous (IV) dose in healthy Asian adult volunteers (Part 2 There may be higher treatment burden for participants in this trial compared to their standard of care. 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, checking for side effects and completing questionnaires.
Phase 1 trials primarily test safety and dosing in a small number of participants (typically 20–100). Results do not yet speak to efficacy. FDA approval is typically many years away from this stage.
Currently recruiting: the trial is enrolling patients. A data readout is not expected until after enrollment closes and the follow-up period is complete.
AbbVie Inc (ABBV) is the sponsoring company for this trial. BiotechSign currently grades this company C (58/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
