COVID-19-Study of Immune Responses Following Vaccination Against SARS-CoV-2
An observational study of Cancer and Elderly, run by Centre Hospitalier Universitaire de Besancon at 1 site in France.
Trial summary
T-cell adaptive immunity is known to be required to sustain a long term immunoglobulin production and a long term memory against several infections. Previous results suggest a lack in the generation of T-cell responses against CoV-N, M and S proteins among cancer patients exposed to SARS-CoV-2 virus highlighting that… Read more about this study

About this study
Official title: Study of Humoral and Cellular Immune Responses Following SARS-CoV-2 Vaccination to Predict Immune Responses in Cancer Patients
T-cell adaptive immunity is known to be required to sustain a long term immunoglobulin production and a long term memory against several infections. Previous results suggest a lack in the generation of T-cell responses against CoV-N, M and S proteins among cancer patients exposed to SARS-CoV-2 virus highlighting that cancer patients failed to mount a protective T-cell immunity. Given this context, our hypothesis is that COVID-19 vaccine candidates are not immunogenic in some cancer patients. Thus, the monitoring of CD4 and CD8 T-cell responses before and after vaccination might provide information related to the correlation between induction of CD4 T-cells (including helper follicular T-cells) by the vaccine and long-term IgG production (serological index). Additionally, the failure of COVID-19 vaccines in some patients should be monitor carefully in order to provide specific recommendations to avoid COVID-19 infections. The main objective is to assess humoral immune responses following COVID-19 vaccination in a population of cancer patients.

Questions about this trial
What is this clinical trial studying?
An observational study of Cancer and Elderly, run by Centre Hospitalier Universitaire de Besancon at 1 site in France.
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 14 inclusion and 2 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 8 Jun 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 France. 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.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact marie kroemer, PharmD, PhD (03 81 66 83 02, mkroemer@chu-besancon.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Rate of virus-specific IgG at 3 months following COVID-19 vaccination measured in plasma to assess humoral immune responses (time frame: 2 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04836793, which also lists 3 linked publications.
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 8 Jun 2021; AzTrials last refreshed its copy on 8 Nov 2026.
