SteRilizing Eye SoLution to ImprovE Patient ComFort (RELIEF)

Study Overview
=================
Brief Summary
-----------------
This is a randomized, double-masked study to evaluate the tolerability and safety of IRX-101 versus 5% povidone-iodine (PI) in subjects receiving intravitreal anti-VEGF injections. The study will be conducted in up to 15 centers in the United States (US).

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: Subjects will be randomized to IRX-101 or Providone-Iodine
Masking: Double


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: IRX-101<br>Subjects randomized to IRX-101 will receive the investigational product, IRX-101. | Drug: IRX-101<br>* IRX-101 is a novel ocular anti-septic<br>|
| Active Comparator: 5% Povidone-iodine<br>Subjects randomized to this arm will receive the standard of care, Providone-iodine, at a concentration of 5%. | Drug: Providone-Iodine<br>* 5% Providone-Iodine<br>|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Safety of new drug | Safety will be measured via slit lamp and fundoscopic examinations | 1-hour and 1-week post-treatment | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Mean corneal fluorescein staining scores | Compare mean corneal fluorescein staining scores obtained after IVT in the IRX-101 and standard of care groups; corneal staining will be obtained using the validated Oxford Corneal Staining scale of 0 (no staining) to 5 (maximal staining) | Immediately following intraviteral injection | 
| Patient-reported post-injection pain scores | Compare mean patient-reported post-injection pain scores 1-hour post-administration; pain will be assessed using the visual analog pain scale, a validated patient-reported outcome measure (questionnaire) for assessing patient's subjective pain and discomfort | 1-hour post-administration |
