Popis: 6567 Background: PILOT (NCT03483103) evaluated liso-cel, an autologous, CD19-directed, CAR T cell product, as 2L tx in pts with R/R LBCL not intended for HSCT. We analyzed changes in health-related quality of life (QOL) with respect to functioning and symptoms in PILOT. Methods: Adults with R/R LBCL after first-line tx were eligible. Pts were deemed not candidates for high-dose chemotherapy and HSCT by their physician and met ≥ 1 frailty criteria: age ≥ 70 yr, ECOG PS = 2, DLCO ≤ 60%, LVEF < 50%, CrCl < 60 mL/min, or ALT/AST > 2 × ULN. Pts completed EORTC QLQ-C30, FACT-LymS, and EQ-5D-5L (health utility index [HUI] and VAS) at screening (baseline [BL]), pre-tx (within 7 days before lymphodepletion), preinfusion on day of liso-cel infusion (Day 1), post-tx on Days 29, 60, 90, 180, 270, 365, 545, and 730/end of study, or at PD. The PRO-evaluable set included all pts with BL and ≥ 1 post-BL assessments. Linear mixed-effects models for repeated measures assessed the least squares (LS) mean change from BL for visits with ≥ 10 pts. Meaningful change from BL was calculated using responder definitions (in points): 10 for EORTC QLQ-C30, 3 for FACT-LymS, 0.08 for EQ-5D-5L HUI, and 7 for EQ-VAS. Results: Among the PRO-evaluable set, completion rates were high (≥ 80%) across most visits for all measures. For EORTC QLQ-C30, mean BL fatigue was meaningfully worse than in a general noncancer population (difference of > 10 points). Overall LS mean changes through Day 545 showed significant improvements in EORTC QLQ-C30 fatigue and pain, FACT-LymS, and EQ-VAS (Table). Improvement for lymphoma symptoms was also clinically meaningful. Fatigue improvement was clinically meaningful with a more sensitive minimal important difference of 4 (Cocks et al, 2012). Significant worsening was not observed for any outcome. In individual patient-level analysis, 70% of pts demonstrated meaningful improvement in FACT-LymS at month 6. Conclusions: Liso-cel meaningfully improved fatigue and FACT-LymS scores without negatively impacting other QOL measures. These data support the clinical evidence of liso-cel as a potential new 2L tx in pts with R/R LBCL not intended for HSCT. Clinical trial information: NCT03483103. [Table: see text]
