Randomized, Phase I/II, Dose-Ranging, Open-Label Trial of the Anti-HIV Activity of Delavirdine Mesylate (DLV; U-90,152S)

Summary

PRIMARY: To study the safety and tolerance of delavirdine mesylate ( U-90152 ) monotherapy. To compare the anti-HIV activity of three blood concentration levels of this agent with nucleoside analog monotherapy, either zidovudine ( AZT ) or didanosine ( ddI ), based on the reduction of HIV viral burden. SECONDARY: To use pharmacokinetic parameters to assess the relationship between daily drug exposure and antiviral activity and toxicity of the U-90152, AZT, and ddI monotherapy. To assess anti-HIV activity using other disease markers. Data suggest that bisheteroarylpiperazines (BHAPs) such as delavirdine mesylate are potent and safe anti-HIV agents and may have different biological behavior than other currently available non-nucleoside RT inhibitors.
