Brief summary

The primary objective of the study is to investigate the efficacy and safety of KPI-121 1.0% ophthalmic suspension compared to placebo in subjects who have undergone cataract surgery.

Detailed description

This is a Phase III, multicenter, double-masked, randomized, placebo-controlled, parallel-group study designed to evaluate the efficacy and safety of KPI-121 1.0% ophthalmic suspension versus placebo in subjects who require treatment of postoperative anterior ocular inflammation.

Inclusion criteria

Candidates for routine, uncomplicated cataract surgery In Investigator's opinion, potential postoperative Snellen Distance VA by pinhole method of at least 20/200 in study eye.

Exclusion criteria

* Known hypersensitivity/contraindication to study product(s) or components. * History of glaucoma, intraocular pressure (IOP) \>21 mmHg at the screening or randomization visits, or being treated for glaucoma in either eye. * Diagnosis of: ongoing ocular infection; severe/serious ocular condition that in judgment of Investigator could confound study assessments or limit compliance; severe/serious systemic disease or uncontrolled medical condition that in judgment of Investigator could confound study assessments or limit compliance; or have been exposed to an investigational drug within the 30 days prior to screening or 18 days following surgery. * In the opinion of Investigator or study coordinator, be unwilling or unable to comply with study protocol or unable to successfully instill eye drops.

Investigators were asked to grade AC cell based on the following scale wherein higher scores indicate a higher degree of cells present and a decrease across time indicates the condition is getting better. Anterior Chamber Cells 0 = No cells seen 1. = 1 - 5 cells 2. = 6 - 15 cells 3. = 16 - 30 cells 4. = greater than 30 cells

Subjects were given the Subject-Rated Ocular Pain Assessment to subjectively rate their pain at Days 1, 4, 8, 15, and the follow-up visit between Days 17 and 19. Higher scores were worse outcomes. The following scoring scale was used for ocular pain: 0 = None 1. = Minimal 2. = Mild 3. = Moderate 4. = Moderately Severe 5. = Severe
