What this research studies

From a patient's point of view, the team is designing new compounds that block two adenosine receptors (A2A and A2B) that help tumors grow and hide from the immune system. They will use AI-guided chemistry and laboratory experiments plus animal testing to make and improve these inverse agonists. The most promising compounds will be readied for further safety testing and eventual human trials. The goal is to create treatment options that work when standard hormone- or HER2-targeted therapies do not.

Who could benefit from this research

Good fit: Ideal candidates would be people with metastatic triple negative breast cancer, especially those whose disease has progressed on standard chemotherapy or shows signs of adenosine-driven immune suppression.

Not a fit: People with non–triple negative breast cancers or whose tumors lack active adenosine signaling may not benefit from these specific drugs.

Why it matters

Potential benefit: If successful, this work could produce new targeted drugs that slow tumor growth, reduce metastasis, and improve outcomes for people with advanced TNBC.

How similar studies have performed: Blocking adenosine signaling has shown promise in lab and early clinical cancer immunotherapy work, but developing inverse agonists specifically for TNBC is a newer and less-tested approach.
