Long-Term Activity of Combining CNCT19 with HDT/ASCT in Refractory Large B-Cell Lymphoma: Two-Year Follow-up of a Prospective Phase 1/2 Clinical Trial (ASH 2022)
Conditioning regimen of GBC/M (Gemcitabine 600 mg/m2/h, infused for 3 hours with loading bolus of 75 mg/m2, day -7, -3, busulfan 105 mg/m2, day -7 until -5, cyclophosphamide 45mg/kg or melphalan 60 mg/m2, day -3, -2) was administered once the CNCT19 product was available...Eighty-nine percent of patients had a history of refractory to first-line immunochemotherapy of R-CHOP (rituximab, cyclophosphamide, adriamycin, vincristine, prednisone) or R-DA-EPOCH (rituximab, etoposide, prednisone, vincristine, cyclophosphamide, and adriamycin), and 72% were refractory to subsequent platinum-based salvage therapy... CNCT19 could be safely administered following HDT/ASCT in patients with relapsed or refractory LBCL. The strategy of combining CAR T-cell therapy with HDT/ASCT might improve response rate and prolong survival compared to CAR T-cell therapy alone.
