The final analysis of the ROSEWOOD study compared a combination of zanubrutinib (a BTK inhibitor) plus obinutuzumab (ZO) versus obinutuzumab alone (O) in patients with relapsed/refractory follicular lymphoma (R/R FL) who had already received two or more prior treatments. With a medium follow-up of 34.6 months, ZO led to improved overall response rates (70% vs 44%) and higher complete responses (42% vs 19%) compared to obinutuzumab. The safety profile was generally manageable, with no new safety signals identified. The most common treatment-emergent adverse events (TEAEs) in the ZO arm were thrombocytopenia, COVID-19, diarrhea, and pneumonia. The most common TEAEs in the O arm were pyrexia, diarrhea, nausea, and neutropenia. Further evaluation of ZO in patients with R/R FL with one or more prior line of treatment compared to lenalidomide plus rituximab in the phase 3 MAHOGANY study is ongoing.
