Study to Understand Relationship Between Gut Health and Toxicities of Hormonal Breast Cancer Treatment (NCT07553234)
Prospective Evaluation of the Gut Microbiome and a Pilot Dietary Intervention in Patients With HR+/HER2- Breast Cancer Receiving Abemaciclib (GEMMA)
🩺 Plain-English Summary (8th-Grade Level)
This study will be conducted in 2 sequential parts. The first part will be a prospective, observational study. This will be followed by a small interventional, pilot study involving use of fiber supplement (chia seeds). The study aims to evaluate the relationship between the gut microbiome (a diverse ecosystem of microorganisms that affects your health and well-being) and treatment-related gastrointestinal toxicities in patients with HR+/HER2- breast cancer receiving abemaciclib plus endocrine therapy.
