History of Changes


This study is a 96-week study designed to evaluate the safety and efficacy of GW873140 in combination with Combivir in HIV infected, untreated subjects.

Condition Intervention Phase
Infection, Human Immunodeficiency Virus I
HIV Infection

Drug : GW873140
Drug : Combivir
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A PhaseIIb, 96 Week, Randomised, Partially Double-blinded, Multicentre, Parallel Group, Repeat Dose Study to Evaluate the Safety, Tolerability, PK and Antiviral Effect of GW873140 in Combination With COMBIVIR (Lamivudine and Zidovudine) Upon Selected Immunological and Virological Markers of HIV-1 Infection in Antiretroviral Therapy Naive Adults

Further study details as provided by ViiV Healthcare:

Primary Outcome Measures

  • Proportion of subjects with viral loads <400 copies/mL remaining on randomized treatment through Week 12
Secondary Outcome Measures:
  • - Comparison of safety and tolerability of different dosage regimens of GW873140 plus Combivir to standard of care regimen. - Assessment of drug resistance over time. - Co-receptor tropism following virological failure.

Estimated Enrollment: 125
Study Start Date: January 2005
Study Completion Date: January 2006
Estimated Primary Completion Date: January 2006 (Final data collection date for primary outcome measure)

Detailed Description:

A Phase IIb, 96 week, randomized, partially double-blinded, multicenter, parallel group, repeat dose study to evaluate the safety, tolerability, pharmacokinetics and antiviral effect of GW873140 in combination with Combivir (lamivudine and zidovudine) upon selected immunological and virological markers of HIV-1 infection in antiretroviral therapy naive adults



Ages Eligible for Study: 18 Years and older  
Sexes Eligible for Study: All  
Accepts Healthy Volunteers: No

  • Active Class C AIDS-defining illness.
  • Laboratory abnormalities at screen.
  • Significant blood loss prior to study start.
  • Pregnant or breastfeeding women.
  • Additional qualifying criteria to be determined by the physician.
