Metformin to lower inflammation in insulin-resistant breast cancer survivors

Pilot Project 1

NIH-funded research Beckman Research Institute/city of Hope · NIH-11177853

What this research studies

You would be invited as a breast cancer survivor with insulin resistance to take metformin under City of Hope care. Doctors will collect blood samples before and after treatment and use advanced single-cell RNA and ATAC sequencing to see how immune cells and gene activity change. The project is run at City of Hope with their IRB and staff while also training University of California, Riverside investigators and technicians in running therapeutic trials and lab methods. Participation focuses on safe, standard-of-care metformin plus research blood draws and lab testing.

Who could benefit from this research

Good fit: Ideal candidates are breast cancer survivors who have evidence of insulin resistance, meet metformin safety criteria, and can attend visits at City of Hope or its affiliated clinics.

Not a fit: People without insulin resistance, those currently receiving systemic cancer treatments, those with contraindications to metformin (for example severe kidney disease), or those unable to travel to City of Hope are unlikely to benefit from this trial.

Why it matters

Potential benefit: If successful, this could show that metformin reduces harmful inflammation and immune changes in insulin-resistant breast cancer survivors, which might improve health and lower recurrence risk.

How similar studies have performed: Metformin has been studied for metabolic and anti-inflammatory effects with some supportive data, but using single-cell and ATAC-seq to map immune changes in breast cancer survivors is a newer, more detailed approach.
