COBALT
A Phase 3, Randomized, Double-masked, Parallel-assignment Study of Intravitreal Bevasiranib Sodium, Administered Every 8 or 12 Weeks as Maintenance Therapy Following Three Injections of Lucentis® Compared With Lucentis® Monotherapy Every 4 Weeks in Patients With Exudative Age-Related Macular Degeneration (AMD).

Brief Summary
The purpose of this study is to compare the safety and effectiveness of bevasiranib given either every 8 weeks or every 12 weeks after an initial pre-treatment with 3 injections of Lucentis® (ranibizumab injection) compared to Lucentis® given every 4 weeks to people with wet AMD. Patients will be assigned at random (like tossing a coin) to receive one of three treatments options for 104 weeks.
