  9. Have uveitis, iritis or congenital aphakia.
  10. Are unwilling to discontinue current glaucoma medication within 30 days of the randomization (Visit 2).
  11. Have had intraocular or periocular surgery within the past 3 months.
  12. Are non-responsive to topical prostaglandins, prostamides or prostaglandin analogs in the Investigator's judgement.
  13. History of previous complicated cataract surgery, or previous refractive keratotomy in either eye.
  14. Used miotics and oral/topical carbonic anhydrase inhibitors within 5 days of screening.
  15. Have any known hypersensitivity to any components of the formulation or latanoprost.
  16. Have participated in a clinical trial for IOP-lowering investigational product or exposure to an IP within the prior 30 days.
  17. In the judgement of the Investigator, have previous or currently active clinically significant systemic or ocular disease in either eye that could affect study outcome.

5. Study Description

Brief Summary
Prospective, double-masked, randomized, multi-center, active-controlled, parallel-group, 3-month study assessing the safety and ocular hypotensive efficacy of TearClear latanoprost Ophthalmic Solution, 0.005% (TC-002) compared to latanoprost Ophthalmic Solution, 0.005% (LAT) in subjects with elevated intraocular pressure at approximately 20 study sites located in the United States
Detailed Description
This is a Phase 3, randomized, investigator-masked, multicenter, parallel-group trial comparing two ophthalmic solution formulations of latanoprost at a fixed dose of 0.005% administered once daily (QD) for 12 weeks. Approximately 300 subjects will be randomized in this study at approximately 20 sites in the United States (US). Treatment assignments will be masked to TearClear, study subjects, Investigators and site staff. Because the container closure for the investigational product is different, this study will use an unmasked dosing coordinator at each study site. All clinical trial supplies will be masked by using carton boxes to mask the appearance of the immediate container closure. At approximately 2 select sites, approximately10% of total randomized subjects will have systemic PK labs drawn. The study involves 7 clinic visits, including Screening (Visit 1), Randomization (Visit 2) and treatment visits (Visits 3, 5 and 7, during which ophthalmic assessments will occur and IOP will be assessed diurnally. There will be two interim IP dispensation visits (Visits 4 and 6).

ParticipantInvestigatorOutcomes Assessor
Masking Description
Treatment assignments will be masked to the Sponsor, subjects, Investigators and select investigative staff, until completion of the study and the final database is locked. The appearance of the bottles in the two treatment arms are not identical; however, the cartons and labeling on the cartons in which the bottles are supplied will be identical and identified with unique kit numbers. Therefore, the dedicated dosing coordinator will handle IP-related responsibilities but will be otherwise uninvolved in study assessments. Appropriate precautions must be taken to prevent unauthorized access to the randomization scheme. Unless the subject's safety requires otherwise and if time permits, the decision to unmask an individual subject's treatment assignment is to be made jointly by the Investigator and Sponsor's medical monitor after consultation with the Sponsor, thus leaving the masking of the remaining subjects intact.
