Naïve HIV POC Monotherapy Trial

NCT ID: NCT00617526

Last Updated: 2014-01-28

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2
• Total Enrollment: 48 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2008-01-31
• Study Completion Date: 2008-08-31

Brief Summary

The primary objective of the trial is:

• to evaluate the change from baseline in plasma viral load with placebo and one of up to 4 dose regimens of RDEA806.

The secondary objectives are:

Efficacy

• to describe the nadir of the plasma viral load
• to describe the DAVG
• to assess the proportion of subjects who reached a drop in viral load of 0.5 log, 1 log, or reach an undetectable viral load
• to assess the plasma viral load decay rate
• to evaluate immunologic changes (as measured by CD4 and CD8 cells)
• to evaluate the genotypic and phenotypic pattern of the virus Pharmacokinetics
• to evaluate the pharmacokinetics and the pharmacokinetic/pharmacodynamic relationship of RDEA806 Safety
• to evaluate the safety and tolerability of bid and qd dosing of RDEA806 as monotherapy
