What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Participants With Treatment Success at Week 8
Treatment success defined as at least a 2-grade improvement from Baseline in the IGA score and an IGA score equating to "clear" or "almost clear" at Week 8. The IGA score was based on a 5-point scale ranging from 0 to 4 (0=clear, 1=almost clear, 2=mild, 3=moderate, and 4=severe). The face, scalp, palms, soles, axillae, and intertriginous areas were excluded from this assessment.
Measured: Week 8
Secondary outcomes (1)
Percentage of Participants With Treatment Success at Weeks 2, 4, 6, and 12
Treatment success defined as at least a 2-grade improvement from Baseline in the Investigator's Global Assessment (IGA) score and an IGA score equating to "clear" or "almost clear" at Weeks 2, 4, 6, and 12. The IGA score was based on a 5-point scale ranging from 0 to 4 (0=clear, 1=almost clear, 2=mild, 3=moderate, and 4=severe). The face, scalp, palms, soles, axillae, and intertriginous areas were excluded from this assessment.
Measured: Weeks 2, 4, 6, and 12 (4-week follow-up)

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing IDP-122 Lotion in people with Plaque Psoriasis, run by Bausch Health Americas, Inc. at 15 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 20 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 15 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 27 Jan 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage of Participants With Treatment Success at Week 8 (time frame: Week 8). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Oct 2026; AzTrials last refreshed its copy on 8 Nov 2026.
