Primary Outcome Measures:
  • A positive response defined as an additional IOP reduction over 10% after 12 weeks of treatment in the intent to treat (ITT) population. [ Time Frame: after 12 weeks of treatment ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Absolute and relative IOP change after 4 and 12 weeks of treatment [ Time Frame: week 4 and 12 ] [ Designated as safety issue: No ]
  • Percentage of patients achieving a target IOP value: under 18 mmHg and under 16 mmHg after 12 weeks of treatment, [ Time Frame: week 12 ] [ Designated as safety issue: No ]
