About this study

Official title: Quantifying Hyperpigmentation Response to Fractionated 1927nm in Fitzpatrick Skin Phototype V and VI: A Pilot Study

The primary objective of this study is to assess the efficacy of 1927nm non-ablative fractionated laser therapy to treat hyperpigmentation in patients ages 18-75 with Fitzpatrick Skin Phototypes V and VI and explore an effective, adjunctive pre- and post-procedural regimen to prevent iatrogenic dyspigmentation or scarring in this population.

Read the detailed description

This single-center clinical trial is being conducted over the course of 7 months, including one Initial Screening Visit (-42 to -28 Days) and three treatments (Day 0, Day 30, Day 60) followed by 1-month and 3-month follow-up visits (Day 90 and Day 120). The primary objective of this study is to assess the efficacy of 1927nm non-ablative fractionated laser therapy to treat hyperpigmentation in patients ages 18-75 with Fitzpatrick Skin Phototypes V and VI and explore an effective, adjunctive pre- and post-procedural regimen to prevent iatrogenic dyspigmentation or scarring in this population.

The Investigators will explore this question with a non-blinded, pilot study at a single center.

Questions about this trial

What is this clinical trial studying?

A study testing MOXI in people with Hyperpigmentation, run by University of Texas Southwestern Medical Center at 1 site 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 17 inclusion and 32 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 15 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 14 Nov 2025). 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?

Change in Spots - Front of Face (Part 1) (time frame: Baseline, 1 Month and 3 Months). The study lists 18 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 15 Dec 2025.
