| الوصف: | 1067 Background: In the IMpassion130 study in 1L mTNBC (N = 902), PFS with atezo + nP was significantly better than with placebo (P) + nP in ITT (HR, 0.80) and PD-L1 IC+ (HR, 0.62) patients (pts). Clinically meaningful OS improvement (HR, 0.62) was also seen in PD-L1+ pts. PROs were used to document pt perspectives on overall clinical benefit of atezo + nP. Methods: Pts received either atezo 840 mg or P q2w + nP 100 mg/m2 on days 1, 8 and 15 of each 28-day cycle until disease progression or intolerance. Pts completed the EORTC QLC-C30 and breast cancer module (QLQ-BR23) on day 1 of each cycle, at end of treatment (Tx) and q4w during follow-up for 1 y. Time to deterioration (TTD; first ≥ 10-point decrease from baseline [BL] held for 2 cycles) in HRQoL was a pre-defined secondary endpoint. Exploratory endpoints included TTD in function, and mean and mean change from BL scores (changes ≥ 10 considered clinically meaningful) in HRQoL, function and disease/Tx-related symptoms. Results: BL completion was 92% (QLQ-C30) and 89% (QLQ-BR23) and remained > 80% through Cycle 20 in both ITT and PD-L1 IC+ pts. No differences in median TTD in HRQoL (ITT: HR, 0.97 [95% CI: 0.80, 1.18]; PD-L1 IC+: HR, 0.94 [95% CI: 0.69, 1.28]), physical function (ITT: HR, 1.04 [95% CI: 0.86, 1.26]; PD-L1 IC+: HR, 1.02 [95% CI: 0.76, 1.37]) or role function (ITT: HR, 1.01 [95% CI: 0.83, 1.22]; PD-L1 IC+: HR, 0.77 [95% CI: 0.57, 1.04]) were observed between arms in either population. Mean scores at BL for HRQoL (ITT: 66.0 [atezo + nP] vs 64.3 [P + nP]; PD-L1 IC+: 67.5 vs 65.0), physical function (ITT: 80.4 vs 79.2; PD-L1 IC+: 82.8 vs 79.4) and role function (ITT: 72.7 vs 71.0; PD-L1 IC+: 73.7 vs 71.7) were similar between arms and throughout the course of Tx. In both arms, HRQoL, physical and role function, and Tx symptoms (fatigue, diarrhea, nausea, vomiting) were stable during Tx, with no clinically meaningful changes seen until pts discontinued Tx. Conclusions: PRO data suggest that atezo + nP was tolerable and similar to nP alone in maintaining HRQoL and day-to-day function relative to BL. This confirms atezo + nP had clinical benefit without compromising HRQoL, physical and role function, or worsening Tx symptoms vs P + nP in 1L mTNBC. Clinical trial information: NCT02425891. |
