ASH 2022: Exploratory Results of PET-CT and Residual Lymph Node Fine Needle Aspiration of Patients Treated with First-Line Venetoclax and Ibrutinib for CLL / SLL; First Interim Analysis of the Phase 2 HOVON 158/Next STEP Trial
The first interim analysis of the Phase 2 HOVON 158/Next Step Trial was conducted halfway through a 15-month course of treatment with ibrutinib and venetoclax. As compared to baseline, PET-CT scanning showed a decrease in metabolic activity in all but one patient. However, despite the decrease in metabolic activity and, in some cases, normal metabolic activity on PET-CT scans, several patients had persistently enlarged lymph nodes.
