About this study
Official title: A Phase 2 Dose-Randomized, Vehicle-Controlled Study of PH-10-Aqueous Hydrogel for the Treatment of Plaque Psoriasis
PH-10 is an aqueous hydrogel formulation of rose bengal disodium (RB) for topical administration to the skin, and is being studied for the treatment of cutaneous skin disorders, specifically psoriasis and atopic dermatitis. This multicenter phase 2 study of subjects randomized sequentially by center to one of four treatment cohorts will assess efficacy and safety of topical PH-10 applied once daily to areas of mild to moderate plaque psoriasis.

What is being measured
The primary outcome is the main question the study is designed to answer.
The primary efficacy endpoint is "Treatment Success," a static endpoint assessed at Day 29 after initial PH-10 treatment and defined as 0 or 1 on all Psoriasis Severity Index (PSI) components and 0 or 1 on the Plaque Response scale.
Measured: 28 days
The primary safety endpoint is incidence of adverse experiences, including pain and dermatologic/skin toxicity (incidence, severity, frequency, duration and causality).
Measured: 8 weeks
Secondary outcomes (3)
Psoriasis Severity Index (PSI) score changes at each visit from Day 1 pre-treatment.
Measured: 8 weeks
Plaque Response score changes at each visit from Day 1 pre-treatment.
Measured: 8 weeks
Pruritus Self-Assessment score changes at each visit from Day 1 pre-treatment.
Measured: 8 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing PH-10 (0.002% Rose Bengal), PH-10 (0.005% Rose Bengal) and PH-10 (0.01% Rose Bengal) in people with Psoriasis, run by Provectus Pharmaceuticals at 4 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 4 inclusion and 9 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 28 Sep 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
The primary efficacy endpoint is "Treatment Success," a static endpoint assessed at Day 29 after initial PH-10 treatment and defined as 0 or 1 on all Psoriasis Severity Index (PSI) components and 0 or 1 on the Plaque Response scale. (time frame: 28 days). The study lists 2 primary outcomes in all. 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 28 Sep 2012; AzTrials last refreshed its copy on 4 Nov 2026.
