简要总结
To compare the safety and efficacy of sevirumab (MSL 109; Protovir), human anti-cytomegalovirus (CMV) monoclonal antibody, plus active primary treatment versus placebo plus active primary treatment in AIDS patients with newly diagnosed and relapsed CMV retinitis.
Ganciclovir and foscarnet are used for treatment of CMV retinitis, but cause hematologic toxicity and nephrotoxicity, respectively. Despite continued maintenance therapy with these drugs, relapse occurs in 85 percent of patients within 4 months. Studies suggest that MSL 109, a human monoclonal antibody, when given with either ganciclovir or foscarnet, may increase initial response and prolong time to progression in patients with CMV retinitis.

Patients are randomized to receive either MSL 109 or placebo every 2 weeks as supplemental therapy to primary CMV treatment.
