History of Changes
To obtain safety and efficacy data for antiretroviral regimens containing emtricitabine in HIV-1 infected pediatric subjects. To determine emtricitabine concentrations in HIV-1 infected pediatric subjects and, if necessary, to refine the dose of emtricitabine to achieve concentrations comparable to those in adults given 200 mg emtricitabine once-daily.
Drug : Emtricitabine
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
|Official Title:||An Open-Label Study of a Once Daily Dose of Emtricitabine in Combination With Other Antiretroviral Agents in HIV Infected Pediatric Subjects|
Further study details as provided by Gilead Sciences:
Primary Outcome Measures
- The primary safety endpoint was tolerability failure (A patient was classified as a tolerability failure if (s)he had any adverse event or laboratory toxicity that lead to the permanent discontinuation of emtricitabine [ Time Frame: Week 48 ]
- The primary efficacy endpoint was defined as the suppression of plasma HIV-1 RNA levels below 50 copies/mL at Week 48 [ Time Frame: Week 48 ]
- Time to loss of virological response (TLOVR) [ Time Frame: Week 48 ]
- plasma HIV-1 RNA change from baseline [ Time Frame: Week 48 ]
- proportion of patients with plasma HIV-1 RNA below 400 copies/mL [ Time Frame: Week 48 ]
- CD4+ change from baseline by study visit [ Time Frame: Week 48 ]
- Proportion of virologic failures [ Time Frame: Week 48 ]
- Incidence of adverse events, laboratory toxicities, and treatment discontinuations [ Time Frame: Week 48 ]
- PK parameters: steady state (0-24hr) plasma AUC for emtricitabine; emtricitabine plasma trough concentration [ Time Frame: Week 2 and between Weeks 8 to 24 ]

|Primary Completion Date:||July 2004 (Final data collection date for primary outcome measure)|
Treatment naive pediatric patients (Group 1: ages 3 to 24 months)were to receive emtricitabine (6mg/kg QD; max 200 mg QD) plus stavudine 1 mg/kg BID (if <30kg)plus lopinavir/ritonavir (12/3 mg/kg BID if >=7 to <15kg; 10/2.5 mg/kg BID if >=15 to <=40 kg)
emtricitabine (6mg/kg QD; max 200 mg QD) plus stavudine 1 mg/kg BID (if <30kg)plus lopinavir/ritonavir (12/3 mg/kg BID if >=7 to <15kg; 10/2.5 mg/kg BID if >=15 to <=40 kg)

Treatment naive or experienced pediatric patients (Group 2: ages 7 to 12 years; Group 3: ages 13-17 years) received emtricitabine (6 mg/kg QD, up to 200 mg QD capsule formulation or up to 240 mg QD using the oral solution) plus didanosine (240 mg/m2 up to 400 mg QD) plus efavirenz (up to 600 mg QD capsule formulation or up to 720 mg QD using the oral solution).
emtricitabine (6 mg/kg QD, up to 200 mg QD capsule formulation or up to 240 mg QD using the oral solution) plus didanosine (240 mg/m2 up to 400 mg QD) plus efavirenz (up to 600 mg QD capsule formulation or up to 720 mg QD using the oral solution).

|Sexes Eligible for Study:||All|
|Accepts Healthy Volunteers:||No|
- Male or female, aged from 3 to 24 months old or from 7 to 17 years old. (Note: This criterion was based on the subject's age at Baseline [Day 1].)
- Documented evidence of HIV-1 infection. (Note: HIV-1 infection had to be confirmed by two positive results obtained in any of the following:
- at any age: HIV culture, HIV DNA PCR, or plasma HIV RNA of >= 10,000 copies/mL;
- age > 4 weeks: neutralizable HIV p24 antigen; or

- Either ART-naïve or ART-experienced, as defined below:
- ART-naïve: no prior exposure to any ART (with the exception of <= 56 cumulative days of perinatal prophylactic treatment for the prevention of maternal-to-child transmission or <=6 weeks of cumulative postnatal treatment with ZDV monotherapy) and a Screening plasma HIV-1 RNA level of >= 5,000 copies/mL and, in children aged >= 7 years old, a plasma HIV-1 RNA of <= 600,000 copies/mL.
- ART-experienced: no previous treatment with an ART regimen(s) that included either lamivudine and/or an NNRTI and a Screening plasma HIV-1 RNA level of <= 600,000 copies/mL.
- Absolute CD4+ cell count of >= 200 cells/mm3.
- Subjects whose parent or other legal guardian provided written informed consent to participate in the study.
- Female subjects of childbearing potential (i.e., post-pubertal) with a negative serum beta human chorionic gonadotropin (Beta-HCG) test at Screening that was confirmed by a negative urine pregnancy test at Baseline, prior to administration of the first dose of emtricitabine.
- If sexually active and/or of childbearing potential, the subject (male and female) had to be willing to use an effective method of contraception while enrolled in the study and for a period of at least 1 month after the last dose of emtricitabine
- Either the subject or the subject's parent or other legal guardian was unable to adhere to the child's dosing schedule and protocol evaluations.
- Female subjects who were pregnant or who were breastfeeding.
