New treatment option for Breast Atypical Hyperplasia
Official title Low Dose Tamoxifen With or Without Omega-3 Fatty Acids for Breast Cancer Risk Reduction
ClinicalTrials.gov ID: NCT06195306
What this study is testing
What is Omega-3-Acid Ethyl Esters?
Omega-3-Acid Ethyl Esters is an investigational medicine, given as an once-daily infusion into a vein, being studied as a potential treatment for breast atypical hyperplasia.
Also referred to as Lovaza.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This phase II trial evaluates tamoxifen, with or without omega-3 fatty acids, for reducing risk of breast cancer among postmenopausal and overweight or obese women who are at increased risk of developing breast cancer. Tamoxifen is a selective estrogen receptor modulator.
- Phase 2: a mid-size study of how well it works
- Which group you join is decided by chance.
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
