About this study
Official title: Determinants of the Level of Anti-SARS-CoV-2 IgG ANTibodiEs After Vaccination in Patients After Organ Transplantation (DANTE-SIRIO 8) Study
Great expectations to control the pandemic are placed in vaccines against COVID-19. Currently, the four COVID-19 vaccines approved in the European Union. The investigators designed a study assessing the anti-SARS-CoV-2 IgG antibody titer after vaccination cycle with the BNT162b2 vaccine in several time points relating these results to the COVID-19 history and severity of symptoms during the disease and after the first and second vaccine dose.
Read the detailed description
The study includes patients of Antoni Jurasz University Hospital No.1 in Bydgoszcz after organ transplantation. To meet the inclusion criteria patients will have to be vaccinated with two doses of the BNT162b2 vaccine. The assessment of the anti-SARS-CoV-2 IgG antibody titer at several time points in each participant. Fresh serum samples were used to measure SARS-CoV-2 IgG on the Siemens Atellica system (Siemens Healthineers, Erlangen, Germany). Results of SARS-CoV-2 IgG were given as U/ml, whereby the cut-off for positivity was defined as ≥1.0 U/ml.

Questions about this trial
What is this clinical trial studying?
An observational study of SARS-CoV2 Infection and SARS-CoV2 Antibodies, run by Collegium Medicum w Bydgoszczy at 1 site in Poland.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 17 Dec 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Poland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

How can a doctor refer a patient or contact the research team?
Contact Emilia Wojtal, MD (+48 52 5854380, terenia4@interia.pl), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
the anti-SARS-CoV-2 IgG antibody concentration 3 months after vaccination cycle with the BNT162b2 vaccine (time frame: 0-12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Dec 2021; AzTrials last refreshed its copy on 8 Nov 2026.
