Feasibility of Lifestyle Intervention in BRCA1/2 Mutation Carriers
A study testing Structured exercise training plus mediterranean diet in people with Hereditary Breast and Ovarian Cancer, run by Technical University of Munich at 3 sites in Germany.
Trial summary
BRCA1/2 mutation carriers have a considerably increased risk to develop breast and ovarian cancer during their lifetime. There is evidence from the literature that for sporadic breast cancer disease risk and the course of disease can be significantly influenced by physical activity, nutrition and weight.

About this study
Official title: Prospective Randomized Multicenter Trial to Assess the Feasibility of a Structured Physical Exercise Training and Mediterranean-style Diet in Women With BRCA1/2 Mutations
BRCA1/2 mutation carriers have a considerably increased risk to develop breast and ovarian cancer during their lifetime. There is evidence from the literature that for sporadic breast cancer disease risk and the course of disease can be significantly influenced by physical activity, nutrition and weight. The hypothesis of this 3 year, prospective randomized multicenter feasibility trial is that a structured life-style intervention program with exercise training and mediterranean diet is feasible and improves the nutritional and fitness status as well as the weight, the quality of life and stress reacting capacity.

Questions about this trial
What is this clinical trial studying?
A study testing Structured exercise training plus mediterranean diet in people with Hereditary Breast and Ovarian Cancer, run by Technical University of Munich at 3 sites 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 1 inclusion and 16 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: finished, as of the sponsor's last update on 16 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Number of patients successfully completing the intervention program (time frame: 3 months). 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 NCT02087592, which also lists 8 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 16 Apr 2024.
