Conditions
COVID-19 Infection
Registration Number
NCT04582903
Lead Sponsor
National Institute of Allergy and Infectious Diseases (NIAID)
Brief Summary

Background:

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19). The global outbreak of COVID-19 is a major public health problem. COVID-19 causes a wide range of symptoms. These symptoms range from mild breathing problems to life-threatening problems or death. Some people have no symptoms. This study aims to learn how acute and late immune responses to COVID-19 lead to different outcomes. The immune system is the body s defense against germs, including viruses, that invade the body.

Objective:

To characterize the immune responses during and after SARS-CoV-2 infection and determine if there is any relationship to clinical course and outcome.

Eligibility:

People ages 0 99 who have confirmed or suspected SARS-CoV-2 infection, people who are not infected despite heavy exposure, and relatives of enrolled participants.

Design:

This is a sample collection protocol to receive send-in biological specimens for exploratory studies, including gene testing. Participants will not be seen at the NIH for study visits.

Study staff will talk with participants health care providers to screen them for the study. Participants enrolled into the protocol will send samples and clinical information at least once and more often if the participant has COVID-19. All participants will provide blood samples and possibly stool. We may also ask for left over specimens from any medical procedures completed as part of medical care. The study staff will also request participants health care providers to complete a survey to collect demographic and medical data. Some of this information may need to be provided directly by the participant.

Pregnant individuals are invited to participate and may be asked to give cord blood samples after delivery. Study findings that affect participants health may be shared with their health care provider. Depending on findings, participants may be contacted to take part in other NIH studies.

Detailed Description

In response to the public health emergency posed by the coronavirus disease 2019 (COVID-19) pandemic, researchers at the National Institute of Allergy and Infectious Diseases (NIAID) are leading a large international collaboration to characterize the innate and adaptive immune responses to acute severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and convalescence. This protocol will allow the NIAID Laboratory of Clinical Immunology and Microbiology (LCIM) to remotely enroll participants for send-in sample collection for analyses to characterize the immune response to SARS-CoV-2, better enabling the LCIM to support NIAID s commitment to safeguarding the health of Americans and people around the world by accelerating research efforts to characterize SARS CoV 2. This is a prospective sample collection protocol to receive send in biological samples (e.g., blood, saliva, stool, and leftover clinically collected samples) for exploratory studies to characterize the immune response to COVID 19. Participants will not be seen at the NIH for study visits. Under this protocol, samples will be collected longitudinally from up to 300 patients with confirmed or suspected SARS CoV 2 infection and sent to the NIH for research evaluations. Additionally, samples will be collected from up to 200 uninfected patients and patient relatives. Testing will be performed to improve understanding of host immune responses to COVID-19, including but not limited to genetic, molecular, and proteomic testing. Findings relevant to participants health and medical care may be returned to them and their referring health care providers or study teams.

Characterization of the dynamic changes of innate and adaptive immune responses during SARS CoV 2 infection and convalescence.End of Study

These endpoints were chosen to provide in depth molecularmeasurements of a wide variety of innate and adaptive host immuneresponses to a novel pathogen in heterogenous patients. This is anexploratory hypothesis generating study to identify findings for validation in future studies. These endpoints are needed to better understand pathogenic mechanisms, improve prognostic tools, optimize existing therapies, and identify new targets for treatment.
