NCT ID: NCT04688996 Recruiting - Plague Clinical Trials

Yersinia Pestis Lateral Flow Immunoassay for Blood Samples

SMARTPRT
Start date: October 19, 2020
Phase:
Study type: Observational

Plague is a deadly but highly treatable disease caused by the bacterium Y. pestis. Due to the historical development of Y. pestis as a bioweapon by several nation states, it is listed by the US as a potential bioweapon that could be used against US warfighters. Although this bacterium is ecologically established worldwide, it mostly affects impoverished people who live in rural low-resource areas of Madagascar. Plague is acquired directly from bites of infected fleas but, if left untreated, it can progress to the highly lethal pneumonic form that can result in human to human transmission. With the dangers of pneumonic plague in the context of both natural outbreak and as a bioweapon used against warfighter, the goal of this study is to investigate a diagnostic test that is able to rapidly and locally diagnose this disease in low-resource settings. This study aims to evaluate a US-developed new LFI (Lateral Flow Immunoassay) assay intended for capillary blood (finger-prick) to diagnose humans infected with Y. pestis. The investigators will rigorously validate with assay on human populations from active plague sites and correlate the results with the results of paired clinical samples used in standard medical workup using existing diagnostics tests.
