End point title |
Change from Baseline in Intraocular Pressure (IOP) in the Study Eye [1] | ||||||||||||
End point description |
IOP is a measure of the fluid pressure inside the study eye. A negative number change from baseline indicates a reduction in IOP (improvement) and a positive change from baseline indicates an increase in IOP (worsening). Due to lack of enrollment, analysis was not performed for this outcome measure.

Substantial protocol amendments (globally) |

Date |
Amendment |
||
30 Jul 2012 |
1) allow the use of Icare and Perkins tonometers; 2) remove PK sampling at baseline; and 3) change the noninferiority margin for analysis of the primary efficacy variable and update sample size calculations accordingly. |
||
19 Apr 2013 |
1) remove evening office visits; 2) change the primary efficacy endpoint to week 6 (hour 2); 3) in the bimatoprost group, change the dosing of bimatoprost to the morning and vehicle to the evening from week 6 to week 12; 4) add a week 8 visit and move pharmacokinetic measurements from week 6 to week 8; 5) change the IOP measurement in weeks 8 and 12 to occur at time 0 (for trough effect); and 6) increase the study sample size to ensure that at least 80 patients were evaluable at weeks 6 and 12 (previous discontinuation rates predicted that approximately 90 patients would be needed to be randomized at baseline, but up to 120 patients could be enrolled if needed). |
