Abstract 1213P
Background
In the pivotal phase III RATIONALE-315 trial (NCT04379635) of patients with resectable stage II to IIIA NSCLC, perioperative TIS plus (+) neoadjuvant platinum-based CT led to a significant improvement in event-free survival [HR=0.56, p=0.0003] compared to placebo + neoadjuvant platinum-based CT. Here, we report results for PRO instruments from RATIONALE-315.
Methods
PROs were secondary endpoints assessed using the EORTC QLQ-C30 and QLQ-LC13 instruments. Key PRO endpoints included QLQ-C30 GHS/QoL, physical function, as well as QLQ-LC13 symptoms of dyspnea, cough, and chest pain. A mixed model for repeated measures was performed at Cycle 1 (baseline), Cycle 3 of neoadjuvant phase, the Cycles 3 and 7 of adjuvant phase. Time to deterioration (TTD) was examined using Kaplan-Meier method. All HRQoL analysis were performed on the intent-to-treat analysis set.
Results
A total of 453 pts were randomized (1:1) to receive neoadjuvant TIS (n=226) or PBO (n=227). By Cycle 7, no meaningful differences in least-squares (LS) mean change from baseline between arms were observed for GHS/QoL, physical functioning, and fatigue, or chest pain and dyspnea (Table); however, the TIS + CT arm experienced a meaningful improvement in LS mean for coughing (-4.37 [95% CI: -9.46 to 0.21]). TTD analysis showed that pts in the TIS + CT arm were at lower risk of worsening for chest pain (HR 0.59 [95% CI: 0.38-0.91]); risk of worsening was similar between the arms in all other PRO endpoints.

Conclusions
Pts in the TIS + chemo arm experienced better HRQoL outcomes than those in the PBO + CT arm in this population of patients with resectable NSCLC, with improvements in coughing and lower risk of chest pain.
