Evaluation of Diagnostic HIV Ag/Ab Combo Assay

July 5, 2011 updated by: Abbott Diagnostics Division

Evaluation of ARCHITECT HIV Ag/Ab Combo Assay

To test blood specimens using a new investigational test that detects antigen and antibody to human immunodeficiency virus (HIV). Results will be compared to an approved HIV antibody test and supplemental testing performed to determine HIV status.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

All specimens collected under separate specimen collection protocols or obtained from specimen suppliers will be provided to the clinical sites performing the investigational HIV test.

This includes 6252 specimens collected from normal healthy individuals (7B5-02-05Z01-01: Collection of Specimens Used in Abbott Laboratories In Vitro Diagnostic HIV and Hepatitis Assays Clinical Studies)and from specimen suppliers. 588 specimens from HIV-infected pediatric subjects and 448 pregnant females at risk for HIV infection collected under protocol (7B5-02-05Z01-02: Collection of Pediatric and Pregnant Female Specimens Used in the Abbott Laboratories In Vitro Diagnostic HIV Assay)and from specimen suppliers. All specimens were previously collected and frozen, except for a subset of 586 specimens from normal healthy population and 55 specimen from pregnant females at risk for HIV infection which were collected under separate specimen collection protocols and tested as fresh specimens during the study.

In addition, 83 specimens that were HIV antigen positive, 1121 specimens that were HIV-1 antibody positive, 201 specimens that were HIV-2 antibody positive, and 1409 specimens from US at risk for HIV infection or from HIV-2 endemic area were all obtained from specimen suppliers, except for 11 pediatric specimens collected under a separate protocol (7B5-02-05Z01-02: Collection of Pediatric and Pregnant Female Specimens Used in the Abbott Laboratories In Vitro Diagnostic HIV Assay).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
