Safety and Effectiveness of Topotecan HCl to Treat HIV-Infected Patients With AIDS-Related Progressive Multifocal Leukoencephalopathy (PML)
The purpose of this study is to see if it is safe and effective to give topotecan through a vein to treat HIV-infected patients with PML, an opportunistic (AIDS-related) infection caused by a virus that infects brain tissue and causes damage to the brain and the spinal cord.
Topotecan fights HIV and the JC virus (the virus that causes PML) in laboratory experiments.
Leukoencephalopathy, Progressive Multifocal
|Study Design:||Endpoint Classification: Safety Study
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||An Open, Comparative Phase II Study of Immediate Versus Delayed Treatment With Topotecan HCl Given as a Continuous 21-Day Infusion Every 28 Days to Patients With AIDS-Related Progressive Multifocal Leukoencephalopathy|
Topotecan, a cytotoxic DNA topoisomerase-I inhibitor that crosses the blood-brain barrier, inhibits the replication of JC virus (the virus that causes PML) in vitro, at concentrations that are not toxic to human cells. Topotecan also inhibits the replication of HIV-1 and the function of Tat (which upregulates the replication of JC virus).
Patients are randomized to be treated immediately with topotecan or to have treatment delayed for 8 weeks. The dosing schedule for patients receiving immediate or delayed treatment is topotecan as a continuous 21-day intravenous infusion every 28 days. All patients must have received optimal, stable antiretroviral therapy for 3 weeks prior to entry and preferably will continue that therapy during the study.
