Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Median VAS Improvement Score as Assessed by Blinded Physician Reviewers
Time Frame: 12 weeks post- final treatment
Improvement (clearing) in solar lentigines as assessed by blinded physician reviewers using a VAS 4 point scale 0-3 where 0=no change and 3=Very much improved.
12 weeks post- final treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percent of Participants With Improvement Score >/=1
Time Frame: 12 weeks post- final treatment
Improvement (clearing) in solar lentigines as assessed by participant using a 4-point VAS 0-3 scale where 0=no change and 3=very much improved. Scores >/=1 indicate improvement.
12 weeks post- final treatment
Percent of Participants Satisfied With Improvement (Clearing) in Solar Lentigines
Time Frame: 12 weeks post- final treatment
Level of Satisfaction with Improvement (clearing) in solar lentigines as assessed by participants, as measured by spot Improvement: 3=Very Much Improved, 2=Much Improved, 1=Improved, and 0=No Change.
12 weeks post- final treatment
Mean Pain Score Associated With Laser Treatments
Time Frame: During treatments
Subjects graded the level of pain associated with each laser treatment, using a 0-10 scale where 0=no pain and 10=worse possible pain, then averaged to get the mean across the treatments.
During treatments
Percent of Subjects With Post-treatment Adverse Event
Time Frame: During study duration 0-6 months.
During study duration 0-6 months.
