- Abstract
The safety and pharmacokinetics of the two neutralizing human IgG1 monoclonal antibodies to cytomegalovirus (CMV) SDZ89-104 and 89-109 in bonemarrowtransplant (BM1)recipients was assessed in an open phase I trial. Thirteen patients, 8 seropositive and 5 seronegative for CMV, were treated with allogeneic or autologous bone marrow transplantation. SDZ 89–104 was given to 5 and SDZ 89–109 to 8 patients. Patients were divided into high-and low-dose groups. A fixed prestudy dose of 0.1 mg/kg was given 4 days before BMT. On days 3, 17, 31,45, 59, and 73, patients were treated with either 0.5 or 2 mg/kg of the respective antibody. Results indicate that doses of 2 mg/kg of SDZ 89–104 or SDZ 89–109 in alternating weeks can be safely administered to BMT patients. Serum trough levels measured by antiidiotype ELISA were ∼10 µg/ml after administration of 0.5 mg/kg and ∼50 µg/ml after treatment with 2 mg/kg of SDZ 89–104 or SDZ 89–109. High serum levels defined by antiidiotype ELISA techniques closely paralleled increased neutralizing activity. Serum half-lives calculatedfrom these data were ∼6 days.
