Carbon Dioxide Laser clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Interventional Study to Evaluate the Appearance of Surgical Scars After Laser Therapy

Start date: November 1, 2016
Phase: N/A
Study type: Interventional

This study evaluates the effect of a fractionated carbon dioxide laser on surgical scars of the face and neck over 12 months. Anyone with a surgical scar on the face and neck who has not had laser therapy may be eligible to participate. The visits occur every three months for up to 12 months. Subjects will be randomly assigned to receive a higher energy treatment or a lower energy treatment during the study. Subjects and raters will be blinded to which therapy level the patient receives. At each visit, the scars will be photographed and the subject will complete a questionnaire to rate the scar prior to treatment. Three physicians will evaluate the scar at each visit. One rater will evaluate the scars in person during the visit, while the other two raters will evaluate the scars using photographs after each visit. During the first three study visits, subjects will receive their assigned treatment, obtain post-treatment instructions, and a diary to record redness, swelling, pain, itching, or other skin changes after treatment. At the third study visit, subjects will have the option to receive additional treatments or terminate their participation in the study. The fourth visit for those who continue will be a treatment visit for one group and the fifth visit will be for data collection, with no treatment offered.
