BACKGROUND AND OBJECTIVE: Few treatment options exist for patients with relapsed/refractory (R/R) B-cell non-Hodgkin lymphoma (NHL) who fail first- and second-line therapies. Pixantrone is a novel aza-anthracenedione agent with reduced potential for cardiotoxicity but maintained anti-tumour activity relative to anthracyclines. The current retrospective, observational, real-life study was undertaken in 79 patients who received pixantrone monotherapy for multiply R/R aggressive B-cell NHL in Spain and Italy. RESULTS: Before pixantrone, patients had received a median of 3 prior therapies and 84.6% of them were refractory to the last regimen. Median progression-free survival (mPFS) was 2.8 months (95% confidence interval [CI] 2.1-3.6) and median overall survival (mOS) was 4.0 months (95%CI 5.6-7.9), with an objective response rate (ORR) of 29% (complete remission [CR]: 13.2%, partial remission [PR]: 15.2%). Patients receiving ≥2 cycles of pixantrone showed mPFS and mOS of 3.1 and 6.0 months, respectively, and an ORR of 36.8% (CR: 17.5%, PR: 19.3%). Overall, 63.3% of patients reported ≥1 adverse event (AE), most commonly haematological AEs. One patient developed grade 2 sinus tachycardia. CONCLUSION: Pixantrone was effective and well tolerated in a real-world population of multiply R/R patients with aggressive B-cell NHL, many of whom had very poor prognostic factors.

Abstract
BACKGROUND AND OBJECTIVE: Few treatment options exist for patients with relapsed/refractory (R/R) B-cell non-Hodgkin lymphoma (NHL) who fail first- and second-line therapies. Pixantrone is a novel aza-anthracenedione agent with reduced potential for cardiotoxicity but maintained anti-tumour activity relative to anthracyclines. The current retrospective, observational, real-life study was undertaken in 79 patients who received pixantrone monotherapy for multiply R/R aggressive B-cell NHL in Spain and Italy. RESULTS: Before pixantrone, patients had received a median of 3 prior therapies and 84.6% of them were refractory to the last regimen. Median progression-free survival (mPFS) was 2.8 months (95% confidence interval [CI] 2.1-3.6) and median overall survival (mOS) was 4.0 months (95%CI 5.6-7.9), with an objective response rate (ORR) of 29% (complete remission [CR]: 13.2%, partial remission [PR]: 15.2%). Patients receiving ≥2 cycles of pixantrone showed mPFS and mOS of 3.1 and 6.0 months, respectively, and an ORR of 36.8% (CR: 17.5%, PR: 19.3%). Overall, 63.3% of patients reported ≥1 adverse event (AE), most commonly haematological AEs. One patient developed grade 2 sinus tachycardia. CONCLUSION: Pixantrone was effective and well tolerated in a real-world population of multiply R/R patients with aggressive B-cell NHL, many of whom had very poor prognostic factors.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
