Comparison of Two Methods in the Treatment of Cytomegalovirus of the Eyes in Patients With AIDS

HIV Infections Clinical Trial

Official title: A Phase II, Double-Masked, Randomized, Placebo-Controlled Evaluation of Standard Therapy vs. Standard Therapy Combined With Human Monoclonal Anti-Cytomegalovirus Antibody (MSL 109) in the Therapy of AIDS Patients With Cytomegalovirus (CMV) Retinitis

Status Completed

Clinical Trial Summary

To evaluate the effect of MSL 109, human monoclonal anti-cytomegalovirus (CMV) antibody, on time to progression of CMV retinitis. To determine the safety and pharmacokinetic profile of MS 109. To evaluate the relationship between pharmacokinetic measurements of MSL 109 and efficacy and virologic markers.

Therapeutic agents currently available for CMV retinitis are limited by their inherent toxicities and short half-lives which require frequent intravenous dosing. Alternatively, MSL 109 has demonstrated safety and effectiveness in neutralizing CMV isolates at concentrations easily maintained in AIDS patients.

Clinical Trial Description

Therapeutic agents currently available for CMV retinitis are limited by their inherent toxicities and short half-lives which require frequent intravenous dosing. Alternatively, MSL 109 has demonstrated safety and effectiveness in neutralizing CMV isolates at concentrations easily maintained in AIDS patients.

Patients receive induction therapy with intravenous ganciclovir or foscarnet daily for 14 days, then are placed on standard maintenance therapy with the induction drug for at least 11 months or until progression. Patients are randomized to receive 1 of 2 doses of MLS 109 or placebo every 2 weeks during induction and maintenance. They are followed at weeks 2 and 4 and every 4 weeks thereafter for 40 weeks. Patients who have not progressed by week 40 continue study drug with follow-up every 2 months until CMV progression occurs. AS PER AMENDMENT 11/29/96: Enrollment onto the current study has been discontinued. To study the enhancement of humoral immunity, a high-dose cohort has been added. Patients are now randomized to MSL 109 given at a higher dose or placebo administered at the same intervals as before. Randomization is weighted 2:1 in favor of high-dose MSL 109. Interim analyses will be performed to provide for early discontinuation, as indicated. Patients randomized under earlier versions may continue on their original study assignment if a study endpoint has not been reached. ;
