About this study

Official title: Influenza Vaccine Study in BRCA1 or BRCA2 Carriers

To evaluate immune function in BRCA1/2 mutation carriers without cancer, specifically to determine whether immune function in healthy individuals with germline loss of function BRCA1/2 mutations, impacts overall immune health and fitness.

Being tested
Seasonal influenza vaccine

What participants receive

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

  • Seasonal influenza vaccineBiological

    To evaluate immune function in BRCA1/2 mutation carriers without cancer following seasonal influenza vaccination

What is being measured

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

  1. To evaluate immune function in female BRCA1/2 mutation carriers without cancer following seasonal influenza vaccination

    Analysis of the primary objective will depend on determination of the strain-specific neutralizing antibody titer change from day 0 to the last study visit, performed as the standard assay as described by the World Health Organization (WHO).

    Measured: 2 years

Secondary outcomes (2)
  1. Exploratory analysis- phenotypic evaluation of B cell

    Phenotypic evaluation of B and T cell responses to vaccine at each timepoint. Phenotypic analysis involves flow cytometry on peripheral blood mononuclear cells (PBMC) from all subjects (10 mL blood per subject).

    Measured: 2 years

  2. Exploratory analysis - transcriptional evaluation

    Transcriptional evaluation of B and T cell responses to vaccine on day 7-10 timepoint. Transcriptional analyses including quantitative real-time PCR (RT-qPCR) and RNA sequencing (RNAseq) may be performed on a subset of the study subjects on the day 7-10 time point.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

An observational study of BRCA1 Mutation and BRCA2 Mutation, run by Abramson Cancer Center at Penn Medicine at 1 site in United States.

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 5 inclusion and 7 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: under way, not looking for participants, as of the sponsor's last update on 8 Jul 2026. 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 United States. 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?

This study is still under way. Results are not available in the source record yet.

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?

To evaluate immune function in female BRCA1/2 mutation carriers without cancer following seasonal influenza vaccination (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 NCT04499534, which also lists 9 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 Jul 2026.
