About this study

Official title: Optimizing Vaccine Responsiveness in HIV-1 and HCV Infections by Identifying Determinants of Responsiveness: A Pilot Study

Infection with either HIV or hepatitis C virus (HCV) affects immune system responses. The purpose of this study is to investigate the immune responses to two different vaccine formulations in HIV-infected, HCV-infected, and HCV/HIV- coinfected individuals.

Read the detailed description

Individuals with HCV and HIV coinfection are especially hard to treat, and as a result, account for a high rate of deaths each year. Because HCV and HIV share transmission routes, HCV/HIV coinfection is common. Liver disease has emerged as a significant cause of death in individuals coinfected with HCV and HIV. Currently, the mechanisms by which HCV and HIV interact in HCV/HIV-coinfected individuals, including how these infections affect immune responses, are poorly understood. Research suggests that vaccination may prevent other comorbidities associated with HCV/HIV coinfection; however, responses to new vaccine antigens have been shown to be impaired in HCV or HIV-infected individuals. The purpose of this study is to identify the innate and adaptive immune defects present in HCV-infected, HIV-infected, and HCV/HIV-coinfected individuals. This study will evaluate whether these innate and adaptive immune defects predict responses to HBV neoantigen in the form of both a diphtheria/tetanus toxoid immunization (Decavac)and a hepatitis A-hepatitis B immunization (Twinrix).

This study will last approximately 24 weeks. Participants will be stratified to one of three arms, based on their HCV and HIV status:

  • Arm A will enroll HCV-infected individuals who are HIV-uninfected
  • Arm B will enroll HIV-infected individuals who are HCV-uninfected
  • Arm C will enroll HCV/HIV-coinfected individuals

Arms B and C will open for enrollment before Arm A. Opening of enrollment for Arm A will be determined by the accrual progress of Arms B and C as evaluated by the ACTG Scientific Agenda Steering committee.

All participants will receive Decavac vaccination on Day 0, and a Twinrix vaccination on Days 0, 7, and 21. Study visits will occur around Days 0, 7, and 21, and at Weeks 6, 8, 12, and 24; all visits will include medical and medication history, blood collection, and a physical exam. Medication to treat HCV or HIV will not be provided by the study.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Twinrix and Decavac in people with HIV Infections and Hepatitis C, run by National Institute of Allergy and Infectious Diseases (NIAID) at 12 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Nov 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in United States, Puerto Rico. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

B-cell humoral responses (time frame: At Week 8). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00393276, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Nov 2021.
