Why Richter's syndrome responds or doesn't respond to treatment

Defining the determinants of response and resistance to therapy for Richter's Syndrome

What this research studies

If you have Richter's syndrome, researchers will collect your blood and tumor samples and connect them to your treatments and outcomes. They will use genetic sequencing, immune profiling, and other laboratory tests to compare tumors from people who respond to newer drug combinations (like PD-1 blockers with ibrutinib or venetoclax plus chemotherapy) versus those who do not. The team will also use patient-derived cell and animal models to test how specific tumor or immune features cause sensitivity or resistance. The goal is to find biomarkers and mechanisms that could guide better treatment choices for future patients.

Who could benefit from this research

Good fit: Ideal candidates are adults with chronic lymphocytic leukemia that has transformed into Richter's syndrome, especially those starting or receiving newer treatments or willing to provide blood and tumor samples and treatment records.

Not a fit: People without Richter's syndrome, those with other cancers, or patients unwilling to share samples and treatment data are unlikely to benefit directly from this project.

Why it matters

Potential benefit: If successful, this work could help doctors choose treatments most likely to work and avoid ineffective options for people with Richter's syndrome.

How similar studies have performed: Some clinical reports show promising responses to combinations like PD-1 blockers with ibrutinib and venetoclax plus chemotherapy, but linking those responses to specific molecular or immune features is still largely novel.
