Estimated Enrollment: 500
Study Start Date: July 1999
Study Completion Date: January 2001
Primary Completion Date: January 2001 (Final data collection date for primary outcome measure)
Detailed Description:
Patients are randomized to 1 of 2 groups for 48 weeks of open-label treatment. Group 1 receives ddI EC plus d4T plus NFV. Group 2 receives Combivir plus NFV. Antiviral activity is determined by the proportion of patients with HIV RNA levels of less than 400 copies/ml at Week 48.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
