Study information
| Primary study design | Interventional |
|---|---|
| Study design | Multicentre, double-masked, placebo controlled, randomised clinical trial. |
| Secondary study design | Randomised controlled trial |
| Scientific title | |
| Study acronym | IM-VIT100 |
| Study objectives | To determine the safety and efficacy of VIT100 (VitrenAse), a proliferating cell nuclear antigen (PCNA) ribozyme (Immusol, Inc. San Diego, CA), in preventing recurrent proliferative vitreoretinopathy (PVR) in patients with established PVR who undergo vitrectomy for retinal reattachment repair. |
| Ethics approval(s) | Columbia University Institutional Review Board reviewed and approved research on the 31st July 2003 (reference number: AAA8110). |
| Health condition(s) or problem(s) studied | Proliferative Vitreoretinopathy |
| Intervention | All patients undergo retinal reattachment surgery with pars plana vitrectomy. Additional intraoperative procedures including scleral buckle placement or revision, pars plana lensectomy or limbal cataract extraction, Intraocular Lens (IOL) implantation or removal, temporary keratoprosthesis and penetrating keratoplasty, retinotomy, and/or gas or silicone oil tamponade could be performed at the discretion of the operating surgeon and required the assistance of an anterior segment specialist in certain cases. All patients were to be randomly assigned to one of the three treatment groups: 0.75 mg or 0.15 mg VitrenAse and placebo (ratio 1:1:1). A single intravenous administration of VitrenAse or placebo was administered after the completion of the vitrectomy procedure. |
