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.

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.

Primary Outcome Measures
NameTimeMethod
Complete Resolution of Anterior Chamber (AC) Cells at Day 8Visit 5 (Day 8) maintained through Visit 6 (Day 15)

Number and percentage of subjects with complete resolution of AC cells in the surgical eye (study eye) at Day 8 maintained through Day 15, without receiving rescue medication prior to Day 15, for KPI-121 1% dosed twice daily (BID) compared with vehicle dosed BID.

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

Complete Resolution of Ocular Pain at Day 8Visit 5 (Day 8) maintained through Visit 6 (Day 15)

Number and percentage of subjects with complete resolution of ocular pain in the surgical eye (study eye) at Day 8 maintained through Day 15, without receiving rescue medication prior to Day 15, for KPI-121 1% dosed twice daily (BID) compared with vehicle dosed BID.

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

Secondary Outcome Measures
NameTimeMethod
Change From Baseline (BL) Anterior Chamber (AC) Cells at Day 4Visit 1 (Baseline) and Visit 4 (Day 4)

The difference in mean changes from BL in AC cell count grade at Day 4 for KPI-121 1% dosed twice daily (BID) compared with vehicle dosed BID.

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

Complete Resolution of Anterior Chamber (AC) Flare at Day 4Visit 4 (Day 4) maintained through Visit 6 (Day 15)

Number and percentage of subjects with complete resolution of AC flare in the surgical eye (study eye) at Day 4 maintained through Day 15, without receiving rescue medication prior to Day 15, for KPI-121 1% dosed twice daily (BID) compared with vehicle dosed BID.

Investigators were asked to grade AC flare based on the following scale wherein higher scores indicate a higher degree of flare present and a decrease across time indicates the condition is getting better.

Anterior Chamber Flare 0 = None

1. = Mild (trace to clearly noticeable, visible)

2. = Moderate (without plastic aqueous humor)

3. = Marked (with plastic aqueous humor)

4. = Severe (with fibrin deposits and/or clots)

Complete Resolution of Ocular Pain at Day 4Visit 4 (Day 4) maintained through Visit 6 (Day 15)

Number and percentage of subjects with complete resolution of ocular pain in the surgical eye (study eye) at Day 4 maintained through Day 15, without receiving rescue medication prior to Day 15, for KPI-121 1% dosed twice daily (BID) compared with vehicle dosed BID.

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
