Drug: Sevirumab

Study type


Funder types



Study No B103

Details and patient eligibility


To determine the safety and tolerance of 3 dosage levels of human anti-cytomegalovirus (CMV) monoclonal antibody (SDZ MSL-109) when administered once every 2 weeks for a total of 8 doses during the maintenance phase of ganciclovir (DHPG) therapy to patients with AIDS and documented evidence of CMV retinitis. In addition for those patients with positive CMV cultures upon entry into this trial a preliminary attempt will be made to assess the potential in vivo antiviral effects of the concomitant administration of DHPG and SDZ MSL-109.
