Safety and Efficacy Study of Small Interfering Ribonucleic Acid (RNA) Molecule (Cand5) to Treat Wet Age-Related Macular Degeneration

This study has been completed.
Information provided by:
OPKO Health, Inc. Identifier:
First received: November 30, 2005
Last updated: August 4, 2008
Last verified: July 2008
The objective of this study is to evaluate the safety and preliminary efficacy of three doses of Cand5. Cand5, a small interfering RNA molecule that selectively silences the mRNA encoding for VEGF.

Condition Intervention Phase
Macular Degeneration Drug: Bevasiranib Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Phase II, Randomized, Double-Masked, Controlled, Dose Comparison Study of Cand5 for Intravitreal Injection for the Treatment of Subfoveal Choroidal Neovascularization Associated With Wet Age-Related Macular Degeneration
