Eyelash Hypotrichosis
Conditions
Brief summary
This study will evaluate the safety and efficacy of bimatoprost solution 0.03% compared with vehicle in Japanese adults with hypotrichosis of the eyelashes.
Interventions
One drop of bimatoprost solution 0.03% applied along each upper eyelid margin once daily in the evening for 4 months.
One drop of bimatoprost vehicle solution applied along each upper eyelid margin once daily in the evening for 4 months.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Participants With at Least a 1-Grade Increase in Overall Eyelash Prominence Using the Global Eyelash Assessment Scale (GEA) | Baseline, Month 4 | The investigator evaluated the patient's eyelash prominence using the GEA 4-point scale: 1= minimal, 2= moderate, 3= marked and 4= very marked at Baseline and Month 4. At least a 1-grade increase in the GEA score from Baseline indicated improvement. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline in Eyelash Length as Measured by Digital Image Analysis (DIA) | Baseline, Month 4 | Photographs were taken of the eyelashes and assessed using DIA. Length was measured in millimeters (mm). Data from both eyes were averaged for each participant for analysis. A positive change from Baseline indicated longer length (improvement). |
| Change From Baseline in Eyelash Thickness as Measured by DIA | Baseline, Month 4 | Photographs were taken of the eyelashes and assessed using DIA. Eyelash thickness (fullness) was assessed across both eyes as an average and is measured in millimeters squared (mm\^2). A positive change from Baseline indicated fuller eyelashes (improvement). |
| Change From Baseline in Eyelash Darkness as Measured by DIA | Baseline, Month 4 | Photographs were taken of the eyelashes and assessed using DIA. Eyelash darkness was measured in both eyes and averaged for analysis using a scale where 0=black and 255=white. A negative change from Baseline indicated darker eyelashes (improvement). |
