Description

Summary

Dolutegravir (DTG) is an HIV drug in the integrase inhibitor drug class. This study will test the safety of and immune response to DTG in HIV-1 infected infants, children, and adolescents.

Official Title

Phase I/II, Multi-Center, Open-Label Pharmacokinetic, Safety, Tolerability and Antiviral Activity of Dolutegravir, a Novel Integrase Inhibitor, in Combination Regimens in HIV-1 Infected Infants, Children and Adolescents

Details

DTG is an HIV medicine in the integrase inhibitor drug class. The purpose of this study is to evaluate the pharmacokinetics, safety, tolerability, and antiviral activity of DTG in HIV-1 infected infants, children, and adolescents.

Participation in this study will last approximately 48 weeks, followed by long-term safety follow-up that will last at least 3 years. Participants may be receiving other antiretroviral (ARV) medications while in this study; these medications will be prescribed by participants' doctors and will not be provided by the study. This study has two stages. Stage I will evaluate the short term tolerability and safety of DTG, allowing the selection of a dose for further study in Stage II. Stage II will then provide long-term safety, tolerability, and efficacy data for DTG. Participants will be assigned to one of nine cohorts depending on age (4 weeks to younger than 18 years of age). Participants in cohorts I and IIA will receive DTG film-coated tablets orally once or twice daily, depending on which other ARV medications they are receiving; participants in cohorts IIB, III, IV, and V will receive DTG granules for oral suspension once or twice daily, depending on which other ARV medications they are receiving; and participants in cohorts III-DT, IV-DT, and V-DT will receive DTG dispersible tablets orally once or twice daily, depending on which other ARV medications they are receiving. (All nine cohorts will be included in Stage I of the study; however, Stage II of the study will not include cohort IIB).

Stage I participants will undergo a physical examination and have blood drawn at each of 10 study visits, occurring on Day 0; Day 5 (+5 days); and Weeks 4, 8, 12, 16, 24, 32, 40, and 48. Stage I participants will also have their blood drawn 8 times over 24 hours during the Day 5 (+5 days) study visit to measure the amount of drug in the blood stream. Stage II participants will undergo a physical examination and have blood drawn at each study visit (Day 0; Day 10; and Weeks 4, 8, 12, 16, 24, 32, 40, and 48). Blood, plasma, and urine will also be stored and tested to measure immune response. Females of childbearing potential will undergo pregnancy testing at every study visit. Questionnaires and assessments will be performed at select study visits.

After 48 weeks, all participants will enter long-term safety follow-up and will continue to receive DTG. During this time, participants will undergo a physical examination, blood collection, and questionnaires at most study visits (every 12 weeks for a minimum of 3 years).

Eligibility

You can join if…

Open to people ages up to 17 years

  • At least 4 weeks but younger than 18 years of age at study entry
  • Confirmed HIV-1 infection defined as positive results from two samples collected at different time points (see protocol for more information)
  • Subjects must belong to one of the ARV exposure groups below:
  • 1) ARV-treatment experienced (not including receipt of ARVs as prophylaxis or PMTCT)
  • Previously took ARVs as treatment, but not currently taking ARVs:
  • Must have been off treatment for greater than or equal to 4 weeks, OR
  • Currently taking ARVs for treatment but failing:
  • Must be on an unchanged, failing therapeutic regimen within the 4 to 12 weeks prior to screening (less than or equal to 1 log drop in HIV-1 RNA within the 4 to 12 weeks prior to screening). NOTE: Dose adjustments for growth or formula substitutions (i.e., switching from single agent to fixed dose combination) are permitted during this 4 to 12 week period. Substitutions of one ARV within the same class for toxicity or tolerability management, or discontinuation of ARVs are also allowed within the 4 to 12 weeks period. OR
  • For subjects less than 2 years of age, initiated ARVs for treatment less than 4 weeks prior to screening.
  • 2) ARV treatment naive (no exposure to ARVs for treatment; could have received ARVs for prophylaxis or PMTCT)
  • Age less than 2 years
  • If an infant has received nevirapine (NVP) as prophylaxis to prevent mother to child transmission (PMTCT), he or she must have not received NVP for at least 14 days prior to enrollment into Stage I or II.
  • HIV-1 RNA viral load greater than 1,000 copies/mL of plasma at screening. NOTE: For subjects enrolling into cohorts IV, IV-DT, V, and V-DT, the HIV RNA test performed at screening may be pending at the time of enrollment. If the screening HIV RNA is less than or equal to 1000 c/mL, the subject should discontinue study drug (see the protocol for more information).
  • Demonstrated ability or willingness to swallow assigned study medications. NOTE: Film coated tablets MAY NOT be crushed or dissolved. Dispersible tablets MAY NOT be cut and must be used in five milligram intervals.
  • Parent or legal guardian able and willing to provide signed informed consent.
  • Female subjects who are of child bearing potential and who are engaging in sexual activity that could lead to pregnancy, must use two adequate birth control methods while on study and for two weeks after stopping study drug. Hormonal birth control alone (e.g., pills, shots, or slow release inserts placed under/on the skin) would not be considered adequate. An effective, medically accepted barrier method of contraception (e.g., female/male condoms, diaphragm or cervical cap with a cream or gel that kills sperm (excluding nonoxydyl-9), intrauterine device [IUD], others) also must be used during the study. Condoms are recommended because their appropriate use is the only contraception method effective for preventing HIV-1 transmission.
  • Males engaging in sexual activity that could lead to HIV-1 transmission must use a condom.
  • Optimized background therapy (OBT):
  • Subjects aged greater than or equal to 2 years of age (Cohorts I, II, III, and III-DT) must have available at least one fully active drug for the OBT to enroll.Historical genotypes obtained within 1 year of screening will be considered by the Protocol Team for determination of fully active drugs if screening genotype testing is inconclusive.
  • Subjects less than 2 years of age (Cohorts IV, IV-DT, V, and V-DT) can enroll if genotype testing has been obtained with results pending. Note: Subjects enrolled with genotype results pending but found to have no active drugs per genotype performed at screening should discontinue study drug (more information can be found in the protocol). However, such subjects who have a greater than 1 log drop in HIV RNA by 4 weeks can continue study drug with approval by the Protocol Team.

  • Any clinically significant diseases (other than HIV infection) or clinically significant findings during the screening medical history or physical examination that, in the investigator's opinion, would compromise the outcome of this study
  • Subject has used, or anticipates using, chronic systemic immunosuppressive agents or systemic interferon (e.g., for treatment of hepatitis C virus [HCV] infection) within 30 days prior to beginning DTG study treatment. Systemic corticosteroids (e.g.,prednisone or equivalent up to 2 mg/kg/day) for replacement therapy or short courses(less than or equal to 30 days) are permitted. (See protocol for more information on disallowed medications.)
  • Any condition that would, in the opinion of the site investigator, place the subject at an unacceptable risk of injury or render the subject unable to meet the requirements of the protocol.
  • Active tuberculosis (TB) disease and/or requirement for treatment that includes rifampin at the time of the screening visit. However, subjects who need rifampin treatment while on DTG will be allowed to continue in P1093 provided the DTG dose is adjusted according to the protocol.
