Venetoclax combinations in untreated CLL: 5-year results and patient-reported outcome analysis of the CLL13/GAIA trial. (PubMed, Blood)
The phase 3 CLL13/GAIA trial assesses three time-limited combinations: venetoclax-rituximab (RV), venetoclax-obinutuzumab (GV), and venetoclax-obinutuzumab-ibrutinib (GIV) compared to chemoimmunotherapy (CIT). Fit patients with CLL without TP53 aberrations were randomized between six cycles of CIT (fludarabine-cyclophosphamide-rituximab [FCR], bendamustine-rituximab [BR]) or 12 cycles of RV, GV or GIV (GIV: ibrutinib continuation until cycle 36 if measurable residual disease [MRD] at months 12/15)...In the GIV arm, clinically relevant QoL improvements occurred later (month 15, after the end of treatment in most patients) than with GV/RV, likely due to a higher treatment-related symptom burden. The trial is registered at clinicltrial.gov with the identifier, NCT02950051.
