Study Summary

This trial is studying a four-drug combination pill to treat HIV-1 in adolescents and children. The objectives are to evaluate the safety and tolerability of the pill and to study how it is processed by the body.

Who is the study for?
This trial is for HIV-1 infected adolescents who haven't had anti-HIV drugs (12-<18 years, over 35kg) and children both new to treatment (6-<12 years, over 25kg) and those already on a stable regimen without resistance to the study drug components. Excluded are those with hepatitis B/C, recent tuberculosis, or pregnant/lactating females.Check my eligibility
What is being tested?
The trial tests E/C/F/TAF single tablet regimens at standard and low doses in different age groups. It aims to understand how the body processes the medication (pharmacokinetics), confirm dosing for effectiveness, and assess safety over a period of up to 24 weeks.See study design
What are the potential side effects?
Potential side effects may include digestive issues like nausea or diarrhea, headaches, fatigue, skin reactions such as rash or itching. Long-term risks could involve bone density changes or kidney function alterations.

Trial Design

3Treatment groups
Experimental Treatment
Group I: Cohort 3: Age ≥2 Years and Weight ≥ 14 to <25 kgExperimental Treatment2 Interventions
Virologically suppressed HIV-infected children (≥ 2 years of age weighing ≥ 14 to < 25 kg) will receive E/C/F/TAF (90/90/120/6 mg) FDC once daily for 48 weeks. Participants who attain a weight of ≥ 25 kg during the course of the study will switch to adult E/C/F/TAF (150/150/200/10 mg) tablets. Participants who complete 48 weeks of study treatment will have the option to receive E/C/F/TAF in an extension phase of the study until: a) the participant turns 18 years old and E/C/F/TAF is commercially available for adults in the country in which the participant is enrolled; b) age-appropriate E/C/F/TAF became commercially available in the country in which the participant is enrolled; or c) Gilead elects to terminate development of E/C/F/TAF in that country.
Group II: Cohort 2: Age 6 to < 12 Years and Weight ≥ 25 kgExperimental Treatment1 Intervention
Virologically suppressed HIV-infected children (6 to < 12 years of age weighing ≥ 25 kg) will receive E/C/F/TAF (150/150/200/10 mg) FDC once daily for 48 weeks. Participants who complete 48 weeks of study treatment will have the option to receive E/C/F/TAF in an extension phase of the study until: a) the participant turns 18 years old and E/C/F/TAF is commercially available for adults in the country in which the participant is enrolled; b) age-appropriate E/C/F/TAF become commercially available in the country in which the participant is enrolled; or c) Gilead elects to terminate development of E/C/F/TAF in that country.
Group III: Cohort 1: Age 12 to < 18 Years and Weight ≥ 35 kgExperimental Treatment1 Intervention
HIV-infected, ARV treatment-naive adolescents (12 to < 18 years of age weighing ≥ 35 kg) will receive E/C/F/TAF (150/150/200/10 mg) fixed-dose combination (FDC) once daily for 48 weeks. Participants who complete 48 weeks of study treatment will have the option to receive E/C/F/TAF in an extension phase of the study until: a) the participant turns 18 years old and E/C/F/TAF is commercially available for adults in the country in which the participant is enrolled; b) age-appropriate E/C/F/TAF become commercially available in the country in which the participant is enrolled; or c) Gilead elects to terminate development of E/C/F/TAF in that country.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Are there other ongoing investigations which concern E/C/F/TAF?

"E/C/F/TAF is being trialed in 25 phase 3 studies, 110 of which are still active. These trials are occurring all over the world with 1680 different clinical trial sites, though many are concentrated in Boylston, Massachusetts."

Answered by AI

What are the most common illnesses that E/C/F/TAF has been shown to be effective for?

"E/C/F/TAF is frequently used to manage human immunodeficiency virus type 1 (hiv-1). However, it also has potential applications in the treatment of hiv infections, hiv transmission, and human immunodeficiency virus type 1 (hiv-1) infection."

Answered by AI

Are there a lot of hospitals participating in this research project in North America?

"Currently, there are 5 sites enrolling patients for this trial. These locations include St. Jude Children's Research Hospital in Memphis, Children's Research Institute in Washington, Miller's Children Hospital in Long Beach, and 2 other undisclosed centres."

Answered by AI

Does this research only pertain to elderly patients?

"For this specific study, only children aged 2 to 17 are eligible. In general, there are 176 clinical trials for drugs involving patients under 18 and 481 studies for elderly patients."

Answered by AI

Are researchers actively recruiting people for this experiment?

"Unfortunately, this trial is no longer recruiting patients as of the most recent update on clinicaltrials.gov from June 10th, 2022. The study was first posted on May 6th, 2013.
