Trial Outcomes & Findings for Phase III Clinical Trial of TRAVATAN Z in Ocular Surface Health (NCT NCT00761319)

NCT ID: NCT00761319

Last Updated: 2012-04-26

Results Overview

The OSDI is a 12-question validated questionnaire (resultant overall 0-100 score) used to measure ocular symptoms, visual function, and environmental factors that may affect a patient's vision, where 0 = normal and 100 = severe. The OSDI questionnaire was administered at both visits and completed by the patient with no assistance from the office staff, physician, or anyone else. A negative number represents a perceived improvement in ocular health.

Participant Flow

Patients were recruited from 78 US study centers. Eligible patients having a diagnosis of open-angle glaucoma or ocular hypertension and on XALATAN® monotherapy for at least one month immediately prior to Visit 1 were enrolled.

705 patients were enrolled in this study. 701 patients were evaluated for safety. Baseline characteristics are presented for all patients who received test article and had at least one on-therapy visit (intent to treat): 652.

PRIMARY outcome

Timeframe: Day 0, Day 90

Population: Intent to treat. All patients who received test article and had at least one on-therapy study visit were evaluable for the intent-to-treat analysis. Last-observation-carried-forward was used to impute values for dropouts and for missing data on a scheduled study visit during the masked treatment period.

SECONDARY outcome

Timeframe: Day 90

Population: Intent to treat. All patients who received test article and had at least one on-therapy study visit were evaluable for the intent-to-treat analysis. Last-observation-carried-forward was used to impute values for dropouts and for missing data on a scheduled study visit during the masked treatment period.

The corneal surface was assessed by the investigator and graded on a scale of 0-3, where 0 = Absent (no staining present) and 3 = Severe (\>50% coverage). Percentage of patients with score = 0 at 90 days was calculated by dividing the number of patients with score = 0 by tht total number of patients analyzed.
