A Randomized Comparison of Intravitreal ISIS 2922 Plus Ganciclovir Versus Ganciclovir as Treatment for Patients With Cytomegalovirus Retinitis ( CMVR )

In Stage 1 of the study, 20 patients receive one of two doses of ISIS 2922 on days 1, 8, and 15 (Induction) then every 14 days (maintenance), with ganciclovir given daily during both Induction and Maintenance. Escalation to the second dose does not occur until all patients at the first dose level have reached their first maintenance dose (day 29). In Stage 2 of the study, 174 patients are randomized to receive either a) ISIS 2922 at the dose established in Stage 1 on days 1, 8, and 15 and then every 14 days, with ganciclovir given daily during both Induction and Maintenance, or b) ganciclovir daily for 14 consecutive days and then a lower dose as maintenance. Patients may continue to receive ISIS 2922 biweekly if the dose is safe and their CMV retinitis is clinically controlled. Per 2/8/96 amendment, patients are now in Stage 2 at 150 mcg.
