Clinical Trial Summary

This surveillance study will collect detailed clinical, laboratory, and radiographic data in coordination with biologic sampling of blood and respiratory secretions and viral shedding in nasal secretions in order to identify immunophenotypic and genomic features of COVID-19 -related susceptibility and/or progression. The aim: for the results obtained from this study to assist in generating hypotheses for effective host-directed therapeutic interventions, to help to prioritize proposals for such interventions, and/or optimize timing for administration of host-response directed therapeutics.

Description:

This is a prospective observational cohort surveillance study of up to 2,000 adult participants hospitalized with known or presumptive COVID-19. Detailed information will be collected regarding patient history and onset of illness upon enrollment. Participants will undergo longitudinal assessments of clinical status and pertinent clinical data (including clinical laboratory values, radiographic findings, medication use, oxygen and ventilatory support requirements, complications, etc.) will be recorded. In parallel, the study will conduct serial biologic sampling for detailed immunophenotyping to provide a comprehensive picture of immune changes that occur throughout the course of infection. The biologic samples to be collected for this observational study include blood, nasal swabs, and endotracheal aspirates. Participants will be followed in hospital through Day 28, unless discharged earlier. If a participant requires an escalation to Intensive Care Unit (ICU)-level care, either within or outside of a dedicated ICU, additional samples will be collected within 24 and 96 hours of care escalation. Convalescent questionnaires and biologic samples will be collected at 3-month intervals up to Month 12 after infection symptom onset, if available. In addition, if a participant is discharged from the hospital prior to Day 28, attempts will be made to collect additional scheduled assessments through Day 28 on an outpatient basis, if feasible.

Eligibility

Inclusion Criteria:

Individuals who meet all of the following criteria are eligible for enrollment as study

participants:

• Participant and/or surrogate understands the data to be collected and the study procedures and is willing to participate in the surveillance cohort as described in the study information sheet;
• = 18 years of age at the time of hospitalization; and
• Admitted to a hospital with presumptive or documented coronavirus disease 2019 (COVID-19), with confirmation of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection by Polymerase Chain Reaction (PCR). Exclusion Criteria: Individuals who meet any of these criteria are not eligible for enrollment as study

participants:

• Underlying medical problems which, in the opinion of the investigator may be associated with mortality unrelated to COVID-19 within 48 hours of hospitalization, or a decision by the patient or surrogate prior to hospitalization to limit care to comfort measures; or
• Medical problems or conditions such as pregnancy which might impact interpretation of the immunologic data obtained.

Intervention

Procedure:
• Biological sample collection
During patient hospitalization: Nasal secretion samples by nasal swabs (for non-intubated patients), whole blood (blood draw/phlebotomy) and sputum secretions by endotracheal aspiration (for intubated patients) will be obtained to proceed with immunologic analysis of samples. DNA will be collected from whole blood at enrollment for genetic analysis (e.g., genome-wide association study [GWAS]). After hospital discharge: Collection of biologic samples (involving nasal swabs and blood draw/phlebotomy) will occur up to 12 months.
• Data Collection: Clinical Care Assessments
Baseline data and assessments obtained as part of ongoing clinical care will be collected throughout hospitalization for COVID-19. After hospital discharge, clinical status and activity assessments will occur up to 12 months.
