Study to Evaluate ISV-305 Compared to Vehicle for Treatment of Inflammation and Pain Associated With Cataract Surgery

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the ocular safety, tolerability, and efficacy of ISV-305 (dexamethasone in DuraSite® 2) compared with Vehicle in the treatment of inflammation and pain associated with cataract surgery.

Detailed Description
-----------------
The purpose of this study is to evaluate the ocular safety, tolerability, and efficacy of topical administration of ISV-305 (0.1% dexamethasone in DuraSite® 2) compared with Vehicle when dosed twice daily for 1 day prior to surgery, the day of surgery and 14 days post cataract surgery.

Eligibility Criteria
-----------------
Inclusion Criteria: Are at least 17 years of age Are scheduled for uncomplicated unilateral cataract surgery Signature of the subject or parent(s) or legally authorized representative on the Informed Consent Form, and when appropriate the minor's assent in accordance with local regulations Are willing and able to follow all instructions and attend all study visits Are willing to avoid disallowed medication for the duration of the study If female is of childbearing potential, agree to and submit a urine sample for pregnancy testing (prior to enrollment and at the end of the study) and use effective contraception for the duration of the study Male subjects whose female partners are not post-menopausal must agree to one of the following: 1) completely abstain from sexual intercourse, 2) use a barrier method (condoms) with spermicide during sexual intercourse for the duration of the study, 3) provide documentation for having had a vasectomy (with documented infertility) Additional inclusion criteria also apply Exclusion Criteria: Have known sensitivity or poor tolerance to any component of the study drugs Have any sign of iritis or scleritis in the study eye Have an acute ocular infection (bacterial, viral or fungal) or active ocular inflammation in the study eye Have any active or chronic/recurrent ocular or systemic disease that is uncontrolled and likely to affect wound healing (e.g., diabetes mellitus, systemic connective tissue disease, severe atopic disease) Have known blood dyscrasia or bone marrow suppression Have any active corneal pathology in the study eye Have had radial keratotomy, corneal transplant, or LASIK in the study eye within the last 2 years Be currently pregnant, nursing, or planning a pregnancy; or have a positive urine pregnancy test Have prior (within 30 days of beginning study treatment) or anticipated concurrent use of an investigational drug or device Have a condition or a situation which, in the investigator's opinion, may put the subject at increased risk, confound study data, or interfere significantly with the subject's study participation Use of any medication the investigator feels may interfere with the study parameters Additional exclusion criteria also apply

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Proportion of Participants With Anterior Chamber Cell (ACC) Grade 0 in Study Eye at Day 15 (Last Observation Carried Forward) in the Modified Intent to Treat (mITT) Population | Biomicroscopic measurement of anterior chamber cells was conducted in the surgery eye (study eye) by the same examiner from visit to visit whenever possible. A slit-lamp biomicroscope was used at x16 magnification with a 1 x 1 mm oblique high-intensity beam. Two cell counts were summed and divided by 2 to determine an average final anterior chamber cell count. This final cell count was converted to a grade: Grades 0, 1, 2, 3, 4 were assigned for cell counts of 0, 1 to 10, 11 to 20, 21 to 50, and > 50, respectively. If the averaged count fell between two grades, the higher grade was selected (e.g., if the two counts were 10 and 11, the average of 10.5 fell into Grade 2). Missing anterior chamber cell grade at Day 15 was imputed by last non-missing scheduled post-baseline anterior chamber cell grade assessed prior to Day 15 (last observation carried forward). | Day 15 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Proportion of Participants Who Achieved a Pain Score of 0 on the Visual Analog Scale (VAS) for Each Post-surgical Assessment | Eye pain/discomfort in the study eye was evaluated at every visit except Visit 2 (Surgery; Day 0) using a VAS, scoring from 0 to 100 using a mark on a 100 mm line (0 = absent; 100 = maximum). Participants were asked to rate the feeling of the symptom in the study eye from absent to extreme by moving a slide on the side of the scale to align with images of descriptive faces. | Day 1 to Day 29 |
