Phase 3 SEQUOIA Trial: Zanubrutinib PFS at 72 Months in Treatment Naïve CLL and SLL
Chronic lymphocytic leukemia, or CLL, and small lymphocytic lymphoma, or SLL, are chronic B cell cancers that often need long term treatment. Many patients are older at diagnosis or have other medical conditions, so the choice of first line therapy is important. Over time the goal is not only to control disease but also to preserve quality of life while keeping side effects manageable.
Targeted therapies have changed how CLL and SLL are treated. Bruton tyrosine kinase (BTK) inhibitors are now commonly used because they offer oral treatment and avoid traditional chemotherapy. Zanubrutinib is a covalent BTK inhibitor that has been studied a lot in the frontline setting. Long term results from the SEQUOIA zanubrutinib study phase 3 PFS data give useful insight into how this approach performs over time compared with chemoimmunotherapy.

MedicalResearch.com: What is the background for this study?
Response: New data from our investigator-sponsored Phase 1 study exploring duvelisib in combination with venetoclax will be presented at ASH on December 7. In relapsed or refractory chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), duvelisib plus venetoclax demonstrated promising clinical activity, a manageable tolerability profile, and identified a recommended Phase 2 dosing (RP2D) regimen.
