Trial Outcomes & Findings for Lopinavir/r or Fosamprenavir/r Switch to Atazanavir/r or Darunavir/r (NCT NCT00756730)

NCT ID: NCT00756730

Last Updated: 2017-08-21

Results Overview

A 10% decline in triglycerides (TGs) was determined to be clinically significant. The percentage of people that experienced a 10% decline was calculated by dividing the number who had a decline of 10% TGs by the total number of participants in the arm.

PRIMARY outcome

Timeframe: baseline, 24 weeks

Population: Two patients in the ATV/r arm discontinued prior to week 24: 1 due to a grade 2 rash, and one due to low level viremia. Neither subject met criteria for virologic failure.

A 10% decline in triglycerides (TGs) was determined to be clinically significant. The percentage of people that experienced a 10% decline was calculated by dividing the number who had a decline of 10% TGs by the total number of participants in the arm.
