OBJECTIVES: I. Evaluate the safety, tolerance, and potential efficacy of 3 doses of human anti-cytomegalovirus (CMV) monoclonal antibody SDZ MSL-109 (MOAB MSL-109) in the treatment of newborns with congenital CMV infection and no central nervous system disease.

II. Determine the relationship between plasma concentrations of MOAB MSL-109 and therapeutic outcome.

III. Determine whether MOAB MSL-109 influences the antibody response and clearance of virus from the urine.

Study Start Date: February 1995
Detailed Description:

PROTOCOL OUTLINE: Patients are treated with human anti-cytomegalovirus monoclonal antibody MSL-109, administered intravenously every other week for a total of 3 doses.

Groups of 6 patients are treated at each of 3 MSL-109 doses; there is no intrapatient escalation.

No concurrent therapy with antibiotics for systemic infection, parenteral antifungal agents, biological response modifiers, or other antiviral agents is allowed.

Patients are followed every 2 weeks for 6 weeks, every 4 weeks for 12 weeks, then annually for 5 years.


Ages Eligible for Study:   up to 29 Days   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
