Safety and Efficacy of Emtricitabine/Tenofovir Alafenamide as Part of Salvage Antiretroviral Regimens in Patients With Uncontrolled Viremia and Drug-Resistant HIV Infection

Background: HIV attacks the immune system. Antiretroviral therapy (ART) is a combination of drugs used for treating HIV infection. For some people, ART drugs stop working against their HIV. Researchers want to see if a different form of the drug tenofovir (an ART drug currently approved by the FDA), combined with another drug, may help people whose HIV is resistant to ART. This combination pill is called F/TAF Objective: To study the safety and efficacy of the drug F/TAF, when used with other ART, for people whose HIV infection has been hard to control with available medicines. Eligibility: People age 14 years and older who have HIV infection and are enrolled in the DOTCOM (14-I-0009) protocol. Design: Participants will be screened with physical exam, medical history, and blood and urine tests. Participants will stay in the hospital for at least 10 days. For the first 9 days, they will take F/TAF by mouth along with their usual ART drugs. In the hospital, they will repeat the screening tests. Participants will have a DEXA scan, an x-ray that measures calcium and other minerals in the bones. Participants will lie on a soft table while the scanner passes over the lower spine and hips. Participants will get a supply of F/TAF and some new ART drugs to take at home. Participants will have follow-up visits in 1, 2, 4, 8, and 12 weeks. After the 12-week visit, they will come back about every 3 months for about 1 year. At these visits, participants will repeat the screening tests. They will discuss any problems taking their ART drugs. They may have another DEXA scan.

1 Interventions

Name: FTC/TAF

Description: Tenofovir alafenamide (TAF) is an investigational oral prodrug of tenofovir. This trial will explore the safety and efficacy of TAF in a fixed combination with emtricitabine (FTC) (F/TAF, Gilead Sciences Inc.) as part of a salvage antiretroviral regimen for HIV-1-infected adults and adolescents (greater than or equal to 14 years) who experienced virologic failure.
Type: Drug
Group Labels: 1

FTC/TAF


Primary Outcomes

Description: An HIV RNA decline of >=0.5 log by day 10 will be considered to be an adequate virologic response, to proceed to the second phase of the study.

Measure: HIV RNA Change From Baseline to Day 10

Time: 10 days

Purpose: Treatment

Allocation: N/A

SNPs


1 K65R

- Where neither TDF nor ABC are optimal NRTI options as defined by at least one of the following criteria: - Presence of the M184V mutation plus TDF-associated resistance mutations based on genotypic/phenotypic testing, specifically K65R alone, or with TAMs (such as 41L, 67N, 70R, 210W, 215Y/F, or 219Q/E) with or without other NRTI-associated mutations; or - FTC/TDF is not considered an option due to impaired renal function (eGFR by Cockroft-Gault equation [eGFR(CG)]=30-60 mL/min), or risk of renal impairment because of conditions such as uncontrolled hypertension, diabetes mellitus, or history of renal toxicity while receiving a TDF-based regimen; and where ABC/3TC is contraindicated (ie, presence of HLA B*5701 allele or history of hypersensitivity reaction to ABC), or is a suboptimal option (eg, presence of ABC-associated resistance mutation(s) or in patients with HBV co-infection). --- M184V --- --- K65R ---

Viral mutations (eg, K65R, multiple thymidine analog mutations (TAMs) can confer resistance or reduced susceptibility to TDF. --- K65R ---


2 M184V

- Where neither TDF nor ABC are optimal NRTI options as defined by at least one of the following criteria: - Presence of the M184V mutation plus TDF-associated resistance mutations based on genotypic/phenotypic testing, specifically K65R alone, or with TAMs (such as 41L, 67N, 70R, 210W, 215Y/F, or 219Q/E) with or without other NRTI-associated mutations; or - FTC/TDF is not considered an option due to impaired renal function (eGFR by Cockroft-Gault equation [eGFR(CG)]=30-60 mL/min), or risk of renal impairment because of conditions such as uncontrolled hypertension, diabetes mellitus, or history of renal toxicity while receiving a TDF-based regimen; and where ABC/3TC is contraindicated (ie, presence of HLA B*5701 allele or history of hypersensitivity reaction to ABC), or is a suboptimal option (eg, presence of ABC-associated resistance mutation(s) or in patients with HBV co-infection). --- M184V ---
