  Purpose
This study will investigate the safety, tolerability, and pharmacokinetics of new formulation of bimatoprost following topical application in patients with alopecia. Two formulations of bimatoprost will be investigated in Part 1 and a third formulation of bimatoprost will be investigated in Part 2. Part 2 will begin after Part 1 has completed.

Primary Outcome Measures:
  • Maximum Plasma Level (Cmax) Following a Single Dose of Bimatoprost [ Time Frame: Day 1 ]
    Cmax is the maximum plasma level following a single dose of bimatoprost. Plasma is the fluid portion of the blood in which the cells are suspended.

  • Maximum Plasma Level (Cmax) Following Multiple Doses of Bimatoprost [ Time Frame: 17 Days ]
    Cmax is the maximum plasma level following multiple doses of bimatoprost. Plasma is the fluid portion of the blood in which the cells are suspended.


Secondary Outcome Measures:
  • Percentage of Patients With Clinically Significant Electrocardiogram (ECG) Findings [ Time Frame: 17 Days ]
    An ECG is a tracing of the heart's electrical activity over time in waves with points identified at P, Q, R, S, and T [measured in milliseconds (ms)], as well as the heart rate [measured in beats per minute (bpm)]. Clinically significant abnormal results include maximum post-treatment QTcB>500 ms, maximum post-treatment QTcF>500 ms, maximum post-treatment QT interval >500 ms, PR interval 25% increase from baseline and >200 ms, QRS interval 25% increase from baseline and >100 ms, heart rate 25% increase from baseline and >100 bpm, and heart rate 25% decrease from baseline and <50 bpm.

  • Number of Patients With an at Least 1-Grade Severity Increase in Local Scalp Tolerability by Patient Assessment [ Time Frame: Baseline, 20 Days ]
    Local scalp tolerability by patient assessment is based on a 4-point scale (0=None, 1=Mild, 2=Moderate, and 3=Severe) for 3 symptoms (burning, itching, and stinging). An at least 1-grade increase from baseline at any timepoint indicates a worsening of symptoms.

  • Number of Patients With an at Least 1-Grade Severity Increase in Local Scalp Tolerability by Dermatologist Assessment [ Time Frame: Baseline, 20 Days ]
    Local scalp tolerability by dermatologist assessment is based on a 4-point scale (0=None, 1=Mild, 2=Moderate, and 3=Severe) for 5 symptoms (dryness/scaling, edema, erythema, folliculitis, and pigmentation). An at least 1-grade increase at any timepoint from baseline indicates a worsening of symptoms.
