The academic point-of-care anti-CD19 chimeric antigen receptor T-cell product varnimcabtagene autoleucel (ARI-0001 cells) shows efficacy and safety in the treatment of relapsed/refractory B-cell non-Hodgkin lymphoma.

Varnimcabtagene autoleucel (var-cel) is an academic anti-CD19 chimeric antigen receptor (CAR) product used for the treatment of non-Hodgkin lymphoma (NHL) in the CART19-BE-01 trial. Here we report updated outcomes of patients with NHL treated with var-cel. B-cell recovery was compared with patients with acute lymphoblastic leukaemia (ALL). Forty-five patients with NHL were treated. Cytokine release syndrome (any grade) occurred in 84% of patients (4% grade ≥3) and neurotoxicity in 7% (2% grade ≥3). The objective response rate was 73% at Day +100, and the 3-year duration of response was 56%. The 3-year progression-free and overall survival were 40% and 52% respectively. High lactate dehydrogenase was the only covariate with an impact on progression-free survival. The 3-year incidence of B-cell recovery was lower in patients with NHL compared to ALL (25% vs. 60%). In conclusion, in patients with NHL, the toxicity of var-cel was manageable, while B-cell recovery was significantly prolonged compared to ALL. This trial was registered as NCT03144583.

A reproducible and safe at-home allogeneic haematopoietic cell transplant program: first experience in Central and Southern Europe.

In 2015, we implemented an at-home allogeneic haematopoietic cell transplant (allo-HCT) program. Between 2015 and 2018, 252 patients underwent allo-HCT; 41 patients underwent allo-HCT in the at-home program (46% myeloablative; 63% unrelated donor; 32% posttransplant cyclophosphamide), and these patients were compared with 39 in-patients; safety, capacity to release beds for other programs, and economic efficiency cost were evaluated. We observed a lower incidence of febrile neutropenia in the at-home group compared with that in the in-patient group (32% versus 90%; p < 0.0001), whereas the incidence of aspergillosis was similar among groups (at-home 1% versus in-patient 3%; p = 0.5). The at-home patients showed a lower incidence of 1-year severe graft-versus-host disease (GVHD; 10% versus 29%; p = 0.03). There were no differences in 1-year transplant-related mortality, relapse, or overall survival among groups. The re-admission rate in the at-home group was 7%. The at-home setting was less expensive (9087 €/transplant), and its implementation increased capacity by 10.5 allo-HCTs/year. Moreover, a chimeric antigen receptor T-cell program could be established without increasing beds. Thus, our at-home allo-HCT program may be a safe modality to reduce febrile neutropenia and acute GVHD, resulting in lower re-admission rates.
