  Purpose
In 2005, there were 50,620 HIV-infected children living in Thailand. Current anti-HIV regimens, comprised of individual pills for each drug, frequently lead to missed doses. To properly control their infection, regimens that are tolerable and effective in children and without pill burden are necessary. The primary purpose of this study is to evaluate the safety and bioavailability of GPO-VIR Z30, a combination fixed dose tablet containing zidovudine (ZDV), lamivudine (3TC), and nevirapine (NVP), in HIV-infected children in Thailand.

Condition Intervention Phase
HIV Infections Drug: GPO-Vir Z30 tablet Drug: Lamivudine Drug: Nevirapine Drug: Zidovudine Phase 1 Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase I/II Comparative Pharmacokinetic Study of the Fixed-Dose Combination (FDC) of Zidovudine (ZDV), Lamivudine (3TC), and Nevirapine (NVP) as GPO-Vir Z30 Pediatric Tablets Versus the Individual Liquid Formulations in HIV-Infected Children Greater Than or Equal to Five Months and Less Than 13 Years of Age in Thailand

Primary Outcome Measures:
  • Safety and comparative bioavailability measured by concentration difference between the GPO-Vir Z30 and standard liquid regimens [ Time Frame: Throughout study ]
  • Therapeutic adequacy of NVP measured by treatment-specific concentration distributions [ Time Frame: Throughout study ]

Secondary Outcome Measures:
  • Comparisons in PK analyses between GPO-VIR Z30 and standard liquid regimens including pharmacokinetic parameters, adverse drug reactions, and the influence of SNPs on NVP pharmacokinetic parameters [ Time Frame: Throughout study ]
Enrollment: 42
Study Start Date: October 2008
Study Completion Date: January 2010
Primary Completion Date: January 2010 (Final data collection date for primary outcome measure)

Detailed Description:

An important factor affecting the therapeutic response to ARVs is adherence. A common reason for poor adherence is high pill burden. A combination fixed dose drug approach appears to be an effective strategy to improve adherence and therapeutic response. In this study, investigators will compare the bioavailability and safety of GPO-VIR Z30, a combination fixed dose drug, with the liquid formulations of ZDV,3TC, and NVP, in children.

This study will last approximately 8 weeks. Participants will be randomly assigned to one of two arms. Participants in Arm 1 will receive GPO-VIR Z30 for 2 weeks before receiving liquid formulations of ZDV, 3TC, and NVP for the following 2 weeks. Participants in Arm 2 will receive liquid formulations of ZDV, 3TC, and NVP for 2 weeks before receiving GPO-VIR Z30 for the following 2 weeks.

This study will consist of 4 study visits after screening. Visits will occur at study entry and on Days 14, 28, and 56. Medical history and a physical exam will occur at all visits. A pregnancy test will occur for females at all visits. Pharmacokinetic tests, involving hospitalization for the 12 hour procedure, will occur on Days 14 and 28. Safety and adherence monitoring will occur by telephone on Days 7, 11 or 12, 13, 21, 25 or 26, 27, and 35. Home visits for directly observed therapy (DOT) may also occur.
