Endpoints

Primary endpoints

  • {"endpoint_text":"- The primary efficacy endpoint will be the difference between Test and Comparator in mean diurnal IOP change from baseline to week 12 visit after adjusting for baseline measurement (week 0).","definition_or_measurement_approach":"Mean diurnal intraocular pressure (IOP) change from baseline to week 12 visit after adjusting for baseline measurement (week 0)."}

Secondary endpoints

  • {"endpoint_text":"- Difference between Test and Comparator in mean diurnal IOP change from baseline to week 2 visit after adjusting for baseline measurement (week 0).\n- Difference between Test and Comparator in mean diurnal IOP change from baseline to week 6 visit after adjusting for baseline measurement (week 0).\n- Frequency of study drugs’ related adverse events.","definition_or_measurement_approach":"Mean diurnal IOP change at weeks 2 and 6 adjusted for baseline (week 0) for the first two endpoints; adverse event frequency assessed as frequency of study drug-related AEs for the safety endpoint."}
