Study start date: October 21, 2020

Actual date on which the first participant was enrolled.

This study aims to recruit adult persons with diagnostically confirmed Corona-Virus- Disease-19 (COVID-19) infection and with different disease manifestation who are included into diagnostic or therapeutic care at the University Hospital Tübingen (UKT). The COVID-19 Next-Generation-Sequencing (NGS) study aims to cover as many patients in Germany as possible. It is expected to include in Phase 1 (pilot study): 250 patients with different disease manifestation (extreme phenotypes) and individual risk factors by whole genome analysis Phase 2 (verification study): 1.000 clinically well-defined patients to ensure a broader range of overlapping phenotypes, to verify data from the pilot study. Phase 3 (confirmation study): > 10.000 patients to increase the power (anticipated).

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details

1000 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Diagnostic Study

Diagnostic studies focus on improving how we detect or confirm a disease. They test new tools or techniques that could provide faster or more accurate diagnoses.

Eligibility

Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.

Treatment Groups
Study Objectives

3 intervention groups are designated in this study

This study does not include a placebo group 

Treatment Groups

Group I

For 150 patients from the extreme phenotypes - complementary to Whole Genome Analysis of each patient also Whole Transcriptome will performed Analysis; DNA methylation analysis using EPIC arrays will be performed in the pilot study (phase 1). Identically, in phase 2 starting from month 4, will be generated WGS, Whole transcriptome sequencing (WTS), and methylation data of the 500 patients. Epigenetic changes are likely to occur upon Corona infection. Subsequently, genome and epigenome data with RNA expression pattern will be correlated.

Group II

Focus on longitudinal analysis of TCR repertoire of CD4+ and CD8+ T cells from blood samples (PBMCs) from clinically characterized patients (n = 24). The bulk- T-cell receptor (TCR) sequencing will be performed at different time points during the course of disease progression and recovery.

Group III

The Severe Acute Respiratory Syndrome-Corona Virus-2 (SARS-CoV-2) viral composition is determined by Next Generation sequencing (different protocols for enrichment are available, and are currently being tested to successfully analyse the virus from different isolates). It is known that SARS-CoV-2 sequence is changing at least one position every second passing from person to person. Numerous variants have been described deriving from 3 different ancestral viruses (named A, B, and C) reflecting different distributions in East Asia, Europeans and Americans. At it is anticipated that other (super)infections may add to the severity of the infection and disease course, the entire metagenome of the throat is being sequenced and analyzed as well.
