A Phase I Study of Combination Therapy With Didanosine (ddI) and Ribavirin in HIV-Infected Children.

Summary

To compare the safety, toxicity, and tolerance of two doses of ribavirin in combination with didanosine (ddI) to HIV-infected children. To determine the toxicity of ddI/ribavirin and compare it to the expected toxicity of ddI monotherapy. To determine the effect of concurrent ribavirin on the pharmacokinetics of ddI. To determine a dosage of ribavirin that would be suitable for a Phase II/III evaluation of ddI/ribavirin. Ribavirin, a broad spectrum antiviral agent, may enhance the antiretroviral activity of didanosine ( ddI ) without a concomitant increase in toxicity. Ribavirin alters the intracellular metabolism of ddI, enhancing the antiretroviral activity of the active form of ddI.
