Brief summary

This study will examine the efficacy and safety of Xalacom comparing with those of Xalatan in Japanese patients with POAG or OH, in order to show superiority of Xalacom over Xalatan in efficacy and similarity of safety between Xalacom and Xalatan.

Pre-assignment details

300 subjects were treated with Xalatan in Run-in period. (Run-in period: subjects treated with Xalatan (0.005% latanoprost eye drop), one drop, once daily in the evening (20:00-23:00).) Of these, 289 subjects were assigned to groups (144 in KP2035 group and 145 in Xalatan group).

Outcome results

Primary

Change of Intraocular Pressure (IOP) From Baseline to Week 8

Value at Week 8 minus value at baseline

Time frame: Baseline to Week 8

Population: The primary efficacy analysis population was the Intent-to-treat population (ITT) which consisted of all subjects treated with the study drug as randomized. If there were any missing IOP values at Week 8, the data were supplemented by LOCF (Last Observation Carried Forward) using data at Week 4.
