About this study

Official title: A Clinical, Laboratorial and Quality of Life Study to Evaluate the Efficacy and Safety of Oral Isotretinoin in the Treatment of Cutaneous Photodamage

This is a randomized, comparative, single evaluator-blinded trial to evaluate clinical, histological and immunohistochemical effects of oral isotretinoin plus moisturizer sunscreen as compared to the use of 0,05% tretinoin cream plus moisturizer sunscreen for the treatment of photodamage on face and forearms. Main oral isotretinoin safety parameters will also be analyzed, as well as adverse events related to topical products.

Read the detailed description

A 24-week study, with 7 or 9 monthly visits, comprising healthy adult volunteers, aged 50 to 75 years will be carried out. The patients should present advanced to severe photodamage on face and forearms. Written informed consent will be obtained from each subject prior to enrollment.

Eligible patients will be randomly divided in two groups:

A- 10 patients will be treated with oral isotretinoin, 20.0 mg/day, every other day, 15 capsules per month, for 24 weeks, associated with the use of moisturizer broad spectrum sunscreen twice a day.

B- 10 patients (controls) will be treated with 0,05% tretinoin cream applied on face and forearms at night and the same moisturizer broad-spectrum sunscreen twice a day.

After randomization, laboratory tests will be requested for patients from group A and will be repeated on weeks 4 and 24.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing oral isotretinoin and Tretinoin in people with Photodamage and Photoaging, run by Federal University of São Paulo at 1 site in Brazil.

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 6 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: status not confirmed, as of the sponsor's last update on 8 Jun 2010. 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 Brazil. 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 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?

Results are not available in the source record.

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?

Clinical, histological and immunohistochemical features before and after treatments (time frame: 24 weeks). 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 8 Jun 2010.
