A Comparative Confirmatory Study of STN1012600 in Subjects With Primary Open Angle Glaucoma or Ocular Hypertension

A Phase III, Randomized, Observer-Masked, Active-Controlled, Parallel-Group, Multicenter Study Assessing the Efficacy and Safety of STN1012600 Ophthalmic Solution 0.002% Compared With Latanoprost 0.005% in Subjects With Primary Open Angle Glaucoma or Ocular Hypertension (Angel-J1 Study)

To investigate whether the IOP lowering efficacy of STN1012600 ophthalmic solution 0.002% is non-inferior to that of latanoprost 0.005% in subjects with POAG or OHT after treatment for 4 weeks.
