DY002: Safety and Effectiveness of DYME as an Agent for Selective Staining of the Anterior Capsule During Cataract Surgery

Study Overview
=================
Brief Summary
-----------------
The primary objective of this study is to test the hypothesis that DYME is safe and effective as a drug to facilitate continuous curvilinear capsulorhexis (CCC) by selectively staining the anterior capsule. Secondary objectives are to compare the safety and effectiveness of DYME to that of a smaller dose of the same API.

Official Title
-----------------
AQNA-DY002: A Double-Masked, Randomized Study of the Safety and Effectiveness of DYME as an Agent for Selective Staining of the Anterior Capsule During Cataract Surgery

Conditions
-----------------
Mature Cataracts

Intervention / Treatment

* Drug: DYME
* Drug: DYME


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Have a cataract sufficiently opaque/mature/brunescent that, in the surgeon's assessment,a dye could facilitate surgery; Be aged at least 18 years old at the time of enrollment; Be in a medical condition suitable for cataract surgery; Able and willing to participate in study examinations and visit schedule; and Understand and freely consent to participate in the study. Exclusion Criteria: In either eye, ocular infection or inflammation within the past 3 months; Known allergy to BBG 250; Uncontrolled intercurrent diseases including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, or cardiac arrhythmia; Active treatment for cancer or systemic infection within the past month; Active treatment with systemic corticosteroids within the past month; Previous participation in this Study for the contralateral eye; Participation in another clinical trial involving an investigational therapeutic during the past 30 days or 5.5 half-lives (if applicable), whichever is longer; Unwillingness to participate in the study or inability to give informed consent; or Any medical condition that in the opinion of the Investigator may compromise the research subject's safety or ability to participate in the study.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Optimal curvilinear capsulorrhexis with a single dose, as assessed by the surgeon based on the tissue dyed and subsequently removed. |  | During surgery | 
| Uncomplicated discharge |  | Three months post-op | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Quality of stain |  | during surgery | 
| Intra-ocular safety of DYME as measured by best corrected visual acuity, corneal endothelial cell count, intraocular pressure, presence/absence of retained dye, duration of surgery, and the absence of dye related adverse events |  | 1-day and 1-week post-op | 
| Intra-ocular safety of DYME as measured by corneal endothelial cell count |  | Three months post-op |
