Description

Summary

The purpose of this study is to examine the pharmacokinetics, safety, and tolerability of abacavir/dolutegravir/lamivudine dispersible and immediate release tablets in HIV-1-infected children less than 12 years of age.

Official Title

Phase I/II Study of the Pharmacokinetics, Safety, and Tolerability of Abacavir/Dolutegravir/Lamivudine Dispersible and Immediate Release Tablets in HIV-1-Infected Children Less Than 12 Years of Age

Details

This study will examine the pharmacokinetics (PK), safety, and tolerability of fixed-dose combination abacavir (ABC)/dolutegravir (DTG)/lamivudine (3TC) dispersible and immediate release tablets in HIV-1-infected children less than 12 years of age.

Children will be enrolled into one of five ABC/DTG/3TC dosing groups based on their weight. The first 5-7 children within each weight-band will undergo intensive PK assessments 5-10 days after starting ABC/DTG/3TC to confirm dose selection. Children will remain on their initial dose of ABC/DTG/3TC through Week 4. After Week 4, ABC/DTG/3TC dosing will be adjusted based on PK results at the individual or weight-band level, and/or an individual child's growth and weight gain over time.

Follow-up study visits for all participants will occur at Weeks 1, 4, 12, 24, 36, and 48. Some participants may attend additional study visits at Weeks 2, 6, 8, 16, and/or 20. Study visits may include physical examination, study drug adherence and tolerability questionnaires, blood collection, and intensive PK sampling. Following the Week 48 study visit, some children may continue on the study for up to 144 weeks.

Eligibility

You can join if…

Open to people ages 2-12

  • Less than 12 years of age at entry
  • Weight 6 kg to less than 40 kg at entry
  • Antiretroviral therapy (ART)-naïve at entry or has been taking a stable ART regimen for at least six consecutive months at entry
  • Note: For ART-naïve children, receipt of antiretroviral (ARV) prophylaxis prior to diagnosis of HIV infection is permitted. For these children, ascertainment of this criterion may be based on parent or guardian report only, but available medical records should also be reviewed in relation to this criterion.
  • Note: For ART-experienced children (on a stable ART regimen), dose and formulation changes (e.g., for growth) within the six months prior to entry are permitted. For these children, ascertainment of this criterion must be based on medical records.
  • For ART-experienced children (on a stable ART regimen), has had a suppressed HIV viral load (HIV-1 RNA less than 200 copies/mL) for at least six consecutive months prior to entry
  • Note: To fulfill this criterion, at least two documented HIV-1 RNA results less than 200 copies/mL must be available, one based on a specimen collected at least six months prior to entry and one based on a specimen collected within 30 days prior to entry.
  • Note: Any documented HIV-1 RNA result greater than or equal to 200 copies/mL based on a specimen collected within six months prior to entry is exclusionary(see exclusion criterion below).
  • At screening, has normal, Grade 1, or Grade 2 laboratory test results for all of the following, based on testing of specimens collected within 30 days prior to entry and grading per the Division of AIDS Table for Grading the Severity of Adult and Pediatric

Adverse Events (refer to the study protocol for guidance on severity grading):

  • Hemoglobin (greater than or equal to 8.5 g/dL or greater than or equal to 5.25 mmol/L)
  • Absolute neutrophil count (greater than or equal to 600 cells/mm3 or greater than or equal to 0.600 x 109 cells/L)

  • Platelet count (greater than or equal to 50,000 cells/mm3 or greater than or equal to 50.00 x 109 cells/L)

  • Estimated glomerular filtration rate (eGFR; bedside Schwartz formula; greater than or equal to 60 ml/min/1.73 m2)

  • Alanine transaminase (ALT) (less than 5.0 x ULN)
  • Aspartate aminotransferase (AST) (less than 5.0 x ULN)
  • Total bilirubin (less than 2.6 x ULN)
  • Direct bilirubin (less than or equal to ULN)
  • Note: Laboratory tests may be repeated during the screening period (i.e., within 30 days prior to entry), with the latest results used for eligibility determination.
  • Note: For treatment-experienced children on an atazanavir-containing ART regimen,Grade 3 or higher total bilirubin is permitted.
  • Confirmed HIV-1-infection based on documented testing of two samples collected at different time points:
  • Sample #1 may be tested using any of the following:
  • Two rapid antibody tests from different manufacturers or based on different principles and epitopes
  • One enzyme immunoassay OR Western Blot OR immunofluorescence assay OR chemiluminescence assay
  • One HIV DNA polymerase chain reaction (PCR)
  • One quantitative HIV RNA PCR (above the limit of detection of the assay)
  • One qualitative HIV RNA PCR
  • One HIV total nucleic acid test
  • Sample #2 may be tested using any of the following:
  • Rapid antibody test. If this option is used in combination with two rapid tests for Sample #1, at least one of the three rapid tests must be United States Food and Drug Administration (FDA)-approved, and the third rapid test must be from a third manufacturer or based on a third principle or epitope.
  • One enzyme immunoassay OR Western Blot OR immunofluorescence assay OR chemiluminescence assay
  • One HIV DNA PCR
  • One quantitative HIV RNA PCR (above the limit of detection of the assay)
  • One qualitative HIV RNA PCR
  • One HIV total nucleic acid test
  • Whole blood, plasma, or serum samples must be tested. If both samples are tested using antibody tests, at least one of the samples must be tested in a laboratory that operates according to Good Clinical Laboratory Practice guidelines and participates in an appropriate external quality assurance program. If nucleic acid testing is used, at least one test must be performed in a Clinical Laboratory Improvement Amendments (CLIA) certified (for US sites) or Virology Quality Assurance (VQA) certified (for non-US sites) laboratory. For tests performed in other settings, adequate source documentation including the date of specimen collection, date of testing, test performed, and test result must be available. FDA approved testing methods should be used when possible.
  • HLA-B*5701-negative based on documented testing at any time prior to entry
  • Note: Documented testing is required even if the potential participant has received ABC prior to study entry.
  • For females of reproductive potential (defined as having experienced menarche), not pregnant based on testing performed at screening
  • For females of reproductive potential who are engaging in sexual activity that could lead to pregnancy, willing to use two methods of contraception while receiving study drug, based on participant and parent or guardian report at entry
  • One of the two methods must be highly effective; highly effective methods include surgical sterilization (i.e., hysterectomy, bilateral oophorectomy, tubal ligation, or salpingectomy) and the following:
  • Contraceptive intrauterine device or intrauterine system
  • Subdermal contraceptive implant
  • Progestogen injections
  • Progestogen only oral contraceptive pills
  • Combined estrogen and progestogen oral contraceptive pills
  • Percutaneous contraceptive patch
  • Contraceptive vaginal ring
  • The highly effective method must be initiated prior to study entry. The second method should ideally be a barrier method. Male or female condom use is recommended with all other methods of contraception for dual protection against pregnancy and to avoid transmission of HIV and other sexually transmitted infections.
  • Based on parent or guardian report at entry, child is expected to be available for 48 weeks of follow-up
  • Parent or guardian is willing and able to provide written informed consent for child's study participation and, when applicable per local institutional review board/ethics committee (IRB/EC) policies and procedures, child is willing and able to provide written informed assent for study participation

You CAN'T join if...

  • Less than two years of age at entry
  • Note: This age restriction reflects ViiV's currently agreed Pediatric Investigative Plan (PIP) and Pediatric Study Plan (PSP). If these plans are modified in the future, such that regulatory agreement is obtained to evaluate ABC/DTG/3TC in children less than two years of age, this restriction will be removed via a protocol Clarification Memorandum. Upon issuance of the Clarification Memorandum, study sites will be permitted to enroll children less than two years of age.
  • Documented resistance to ABC, DTG, or 3TC
  • Note: Testing to rule out resistance is not required, and the M184V resistance mutation is not exclusionary.
