Study groupRoleWhat they receive
Vitamin C & Vitamin EExperimentalAfter subjects undergo UVB treatment then they will be instructed to take two Vitamin C and one Vitamin E tablets daily for 8 days.
Receives: Dietary Supplement: Vitamin C; Dietary Supplement: Vitamin E

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in microvesicle particles (MVP) levels from baseline

    Levels of microvesicle particles will be determined from skin biopsies

    Measured: Day 8

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Vitamin C and Vitamin E in people with Ultraviolet B Radiation and Microvesicle Particles, run by Wright State University 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 3 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 24 Feb 2023. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Change in microvesicle particles (MVP) levels from baseline (time frame: Day 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 24 Feb 2023; AzTrials last refreshed its copy on 31 Oct 2026.
