Trial summary

Many cancer patients are highly susceptible to infection and respond poorly to vaccination. This observational study will determine molecular and cellular features of immunity to viral pathogens in participants with cancer and compare them to healthy controls. Read more about this study

About this study

Official title: Systems Biology Analysis of Vaccine-induced Immunity to Infectious Diseases in Healthy Participants and Participants With Cancer

Many cancer patients are highly susceptible to infection and respond poorly to vaccination. This observational study will determine molecular and cellular features of immunity to viral pathogens in participants with cancer and compare them to healthy controls. The aim is to identify how antiviral immunity in participants with cancer differs from that in healthy participants to understand why cancer patients are more susceptible to infections. In this context, the investigators will also evaluate immunity to medically indicated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and seasonal influenza vaccine received by study participants during standard care (vaccines are not part of the study).

Read the detailed description

Cancer and its treatments are associated with dysregulated immune systems, and cancer patients are highly susceptible to infections (e.g., influenza, SARS-CoV-2). Importantly, cancer patients often respond poorly to vaccination. The molecular and cellular mechanisms underlying immune dysregulation and poor immunity in cancer patients are manifold, variable among individual patients/conditions, and poorly understood. An in-depth understanding of these mechanisms is essential to identifying novel strategies to prevent infectious diseases and developing individualized therapies.

In this observational study, the investigators will collect blood samples from 200 participants with hematological and oncological malignancies and healthy participants and analyze the cellular and humoral immune status in the context of SARS-CoV-2 and influenza infection and vaccination within these samples using systems biological tools. Medically indicated vaccination against SARS-CoV-2 and influenza during study participation is allowed.

This study aims to (1) examine the fundamental innate, cellular, and humoral immune responses to pathogens that form the basis of immunological memory and (2) identify molecular and cellular mechanisms responsible for the reduced immune immunity to viral pathogens in participants with cancer.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Biological sample collectionProcedure or surgery

    Whole blood (blood draw/phlebotomy) will be obtained to proceed with immunologic analysis of samples. Collection of biologic samples will occur up to 12 months.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Differences in virus-specific antibody levels

    Determination of differences in plasma and serum antibody levels between healthy participants and participants with cancer.

    Measured: 12 months

  2. Differences in cytokine levels

    Determination of differences in plasma and serum cytokine levels between healthy participants and participants with cancer.

    Measured: 12 months

  3. Differences in immune cell composition

    Determination of quantitative, phenotypical, and functional differences in immune cells from healthy participants and participants with cancer.

    Measured: 12 months

  4. Differences in molecular immune cell makeup

    Determination of epigenetic, transcriptional, and proteomic makeup of immune cells from healthy participants and participants with cancer.

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

An observational study of Influenza and SARS-CoV-2, run by University Hospital Tuebingen at 1 site in Germany.

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 4 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 9 May 2024. 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 Germany. 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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Differences in virus-specific antibody levels (time frame: 12 months). The study lists 4 primary outcomes in all. 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 9 May 2024.
