Better treatments for metastatic breast cancer using patient-derived tumor models
Research Project 2: Identify and validate efficacious therapies for metastatic breast cancer
Researchers use lab-grown tumor models made from people with metastatic breast cancer to find drug combinations and molecular markers that could help pick better treatments.

What this research studies
This project uses tumor samples from people with metastatic breast cancer to grow lab models such as patient-derived xenografts (PDX), organoids, and tissue slices. Those models are exposed to many drugs and drug combinations to see which ones shrink tumors in the lab and in mouse models. Genetic and molecular data are compared to drug responses to find biomarkers that predict who will respond. Computer algorithms then prioritize the most promising combinations for future clinical testing and NCI-IND treatment development.
Who could benefit from this research
Good fit: People with metastatic breast cancer—especially those who can provide tumor tissue or have had samples saved from surgery or biopsy—are the most likely candidates to benefit or participate in related trials.
Not a fit: People with early-stage breast cancer, or patients without available tumor samples, are unlikely to benefit directly from this preclinical modeling work.
Why it matters
Potential benefit: If successful, this work could lead to new drug combinations and matching tests that give people with metastatic breast cancer more effective, personalized treatment options.
How similar studies have performed: Previous laboratory and animal studies using organoids and PDX models have shown promising agreement with tumor drug responses, but translating these findings into standard clinical treatments is still emerging.
