Primary Completion Date: August 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Single Arm: ATS907
Single-cohort, dose-escalation
Drug: ATS907
Single dose of each of three increasing concentrations


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • 18 years of age or greater
  • Diagnosis of open angle glaucoma or ocular hypertension in both eyes
  • Corrected visual acuity in each eye +1.0 logMAR or better by Early Treatment Diabetic Retinopathy Study (EDTRS) in each eye (equivalent to 20/200)
  • Must be willing to discontinue the use of all ocular hypotensive medications in both eyes prior to and during the entire course of the study

Exclusion Criteria:

Ophthalmic (in either eye):

  • Glaucoma: pseudoexfoliation, steroid induced, pigment dispersion glaucoma, and or history of angle closure. Previous glaucoma intraocular surgery or glaucoma laser procedures in study eye(s). Refractive surgery in study eye
  • Cataract surgery and or other intraocular surgery within one month prior to Screening in either eye
  • History within 3 months prior to Screening of clinically significant moderate or severe chronic or active ocular infection, inflammation, blepharitis, dermatitis, uveitis or conjunctivitis
  • Clinically significant corneal dystrophy, epithelial and or endothelial disease, corneal irregularities and or scarring such that reliable applanation tonometry would prevented
  • Contact lens wear during the duration of the study
  • Clinically significant ocular disease (e.g., diabetic retinopathy, macular degeneration, or uveitis) which might interfere or progress during the study
