A Phase I Open-Label Study of the Safety, Tolerance, and Pharmacokinetic Interactions of Combination Didanosine and Ribavirin in HIV-Positive Individuals

Summary

To evaluate the safety and tolerance of concurrent administration of standard-dose didanosine (ddI) with low-dose ribavirin in HIV-positive patients. To determine the pharmacokinetic interactions of concurrent administration of ddI and ribavirin and correlate pharmacokinetic parameters with toxicity. To investigate antiviral activity of the combined regimen. Combination ddI/ribavirin therapy, if safe and effective, offers an alternative combination antiretroviral regimen for patients unable to tolerate regimens containing zidovudine (AZT).
