Study of Denufosol (INS37217) in Subjects With Rhegmatogenous Retinal Detachment
This study has been terminated.

The purpose of this study is to test if denufosol will remove the fluid build-up in the eye so that the retina can be re-attached without invasive surgery.
Drug: denufosol tetrasodium (INS37217) Intravitreal Injection
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Primary Purpose: Treatment
||A Randomized, Double-Masked, Placebo Controlled, Parallel Group, Multi-Center, Dose-Ranging Study of Denufosol Tetrasodium (INS37217) Intravitreal Injection in Subjects With Rhegmatogenous Retinal Detachment
Primary Outcome Measures:
- Compare safety and tolerability of single and/or multiple intravitreal injections of three dose levels of denufosol vs. placebo
- Compare efficacy of denufosol vs. placebo as a treatment for detachment of the retina in RRD subjects
Secondary Outcome Measures:
- Identify one or more dose levels of denufosol as safe and potentially effective to warrant study in Phase 3
- Evaluate utility of 3D B-scan ultrasound technology as endpoint for objectively describing volume of retinal detachment

| Primary Completion Date:
||April 2006 (Final data collection date for primary outcome measure)
The purpose of this trial is to determine if administration of denufosol is well-tolerated and more efficacious than placebo in stimulating subretinal fluid reabsorption and retinal reattachment without surgical intervention in subjects presenting with rhegmatogenous retinal detachment.
|Ages Eligible for Study:
||18 Years and older
|Genders Eligible for Study:
|Accepts Healthy Volunteers:
- have rhegmatogenous retinal detachment in only one eye
- be able to receive intravitreal injection of study drug and be able to wait 24(+/- 6) hours to have detachment surgically treated or retinal breaks repaired per judgement of investigator
- no more than 3 separate identifiable retinal breaks that are clustered together and confined within an area no more than 2 clock hours in extent
- retinal detachment must be large enough such that it cannot be immediately repaired with laser photocoagulation or cryotherapy
- have pinhole acuity (using ETDRS) of macula-on, 20/50 or better in both eyes OR macula-off, 20/50 or better in non-study eye and have history, prior to detachment, of reading capability in study eye
- have a non-rhegmatogenous retinal detachment
- have large retinal break(s) whose total break area is greater than 1 clock hour in extent
- have evidence of atrophic retinal pigment epithelium, choroid, choroidal detachment or intraocular inflammation
- be monocular
- have a prior retinal detachment repair or a congenital condition that places a greater risk for rhegmatogenous retinal detachment
- have proliferative vitreoretinopathy greater than grade B
- have pre-existing subretinal or vitreous hemorrhage, corneal opacity, or other conditions which limit the view of peripheral retina
- have any co-existing macular pathology or other retinal conditions that can limit visual acuity
- currently have uncontrollable elevated intraocular pressure, advanced glaucoma, or any history or current evidence of endophthalmitis in the affected eye
- have symptoms consistent with a rhegmatogenous retinal detachment such as visual disturbance greater than 14 days prior to screening if macula-on OR history of loss of reading vision in affected eye for greater than 6 days prior to screening if macula-off
- have a retinal detachment with evidence of demarcation lines or evidence of subretinal fibrosis visible upon fundus examination
- be currently taking medications that could obscure or confound study results including acetazolamide (Diamox) and dorzolamide
- have had a periocular, retrobulbar or intravitreal injection in the affected eye, including corticosteroids in the 3 months prior to screening or require one
