Outcome Measures

Primary Outcomes (1)

  • The Proportion of Participants Cured Based on Their Collarette Score of 0 for the Upper Eyelid.

    The proportion of subjects cured where cure is defined as 0-2 lashes with collarettes on the upper eyelid of the analysis eye. The primary outcome analysis is the combined result from 20 analyses each with missing data imputed. Missing data were imputed per the method described in the SAP. The least square mean is computed from the result of the 20 analyses with imputed missing values

    43 days

Secondary Outcomes (3)

  • The Proportion of Participants With Their Demodex Mites Eradicated.

    43 days

  • The Proportion of Participants Cured Based on a Composite of Collarette Score and Erythema Score

    43 days

  • The Proportion of Participants Cured Based on Erythema Score.
