A Phase I/II Trial of Ribavirin (With Escalation) + Isoprinosine in Asymptomatic HIV-Viremic Patients

Summary

To determine the safety and effectiveness of treatment with ribavirin (RBV) plus isoprinosine (INPX) in preventing the development of AIDS in patients infected with the AIDS virus (HIV). Also to determine the maximal dose of RBV that can be tolerated by HIV-infected patients when RBV is given with INPX. The patients may or may not have generalized lymphadenopathy syndrome (LAS). RBV has prevented the development of AIDS in some HIV-infected patients with LAS and INPX has stimulated the immune system of patients infected with HIV. The immune system fights infections in the human body, and the HIV attacks T cells that are an important part of the immune system. Reports from individual cases treated with both RBV and INPX suggest that clinical improvements occurred in HIV-infected patients, but there is no reliable information on the safety and effectiveness of this drug combination in such patients.
