NCT00000803
First received: November 2, 1999

  Purpose

To determine the safety and anti-HIV activity of delavirdine mesylate ( U-90152 ) in combination with zidovudine ( AZT ) and/or didanosine ( ddI ) versus AZT/ddI combination.

U-90152 has demonstrated anti-HIV activity. Since the combination of this drug with either AZT or ddI has synergistic inhibitory activity against HIV-1 in vitro, and triple therapy appears to have greater inhibitory activity against HIV-1 in vitro than dual therapy, the use of U-90152 in combination with AZT and/or ddI may improve the benefits of these drugs in persons with HIV disease.

Detailed Description:

U-90152 has demonstrated anti-HIV activity. Since the combination of this drug with either AZT or ddI has synergistic inhibitory activity against HIV-1 in vitro, and triple therapy appears to have greater inhibitory activity against HIV-1 in vitro than dual therapy, the use of U-90152 in combination with AZT and/or ddI may improve the benefits of these drugs in persons with HIV disease.

Patients are randomized to receive U-90152/AZT/ddI, U-90152/AZT, U-90152/ddI, or AZT/ddI for 48 weeks.
