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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

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
At the end of the study (day 168), evolution of the percentage of healthy surface versus baseline, was evaluated by a blinded investigator. Comparison with the comparator product.
Time Frame: After 168 days of treatment
Percentage healthy surface was assessed using digital image analysis. Briefly, two macro-photographs (top and front) were made of the great toenail, placed beside a piece of graph paper to allow determination of the exact size of the nail during analysis (contour tracing). Consequently, all pictures were digitalised and recorded on the computer. Image analysis of the top picture was performed with Adobe Photoshop software. For each photograph, a blinded dermatologist traced the healthy surface.
After 168 days of 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
At different time points, evolution of the percentage of healthy surface versus baseline, was evaluated by a blinded investigator. Comparison with the comparator product.
Time Frame: After 14, 28, 56 and 112 days of treatment
Percentage healthy surface was assessed using digital image analysis. Briefly, two macro-photographs (top and front) were made of the great toenail, placed beside a piece of graph paper to allow determination of the exact size of the nail during analysis (contour tracing). Consequently, all pictures were digitalised and recorded on the computer. Image analysis of the top picture was performed with Adobe Photoshop software. For each photograph, a blinded dermatologist traced the healthy surface.
After 14, 28, 56 and 112 days of treatment

Time Frame: On Day 0, Day 14, Day 28, Day 56, Day 112 and Day 168

Onycholysis, nail dystrophy, nail discoloration and nail thickening were assessed using the following scores:

0 = none, 1 = very slight, 2 = slight, 3 =moderate, and 4 = severe.
On Day 0, Day 14, Day 28, Day 56, Day 112 and Day 168
Evaluation of the microbiological efficacy of the product assessed by fungal culture and comparison with the comparator product.
Time Frame: On baseline (day zero) and day 168
On baseline (day zero) and day 168
