A Study to Evaluate How the Study Drug Moves Through the Body, Adverse Events, and How the Body Tolerates ABBV-547 Injections
United States, Japan121 participantsStarted 2025-11-24
Plain-language summary
The purpose of this study is to assess how safe, effective, and tolerable ABBV-547 is in adult participants in the United States and Japan.
There will be 2 parts to this study. In Part 1, participants are placed in one of 7 groups where they will receive ABBV-547 at different doses or placebo. There is a 1 in 4 chance participants will receive placebo. In Part 2, participants are placed in one of 3 groups where they will receive ABBV-547 at different doses or placebo. There is a 1 in 7 chance participants will receive placebo. Approximately 121 adult participants will be enrolled at approximately 21 sites in the United States and Japan.
Participants will be administered one dose of ABBV-547 or placebo.
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.

Inclusion Criteria:
* A condition of general good health, based upon the results of a medical history, physical examination, vital signs, laboratory profile and a 12-lead electrocardiogram (ECG).
* Part 1: BMI is \>= 18.0 to \<= 29.9 kg/m\^2 after rounding to the tenths decimal at Screening. BMI is calculated as weight in kg divided by the square of height measured in meters.
* Part 2: must have discontinued use of phototherapy (e.g., UVA or UVB) at least 2 weeks prior to the baseline visit (Day 1) and PUVA phototherapy at least 4 weeks prior to the baseline visit (Day 1).
Exclusion Criteria:
* History of any clinically significant sensitivity or allergy to any medication or food.

* Part 2: received any biologics including investigational agents within 2.5 half-lives prior to Baseline.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
