Abstract 164O

Background

KEYNOTE-355 (NCT02819518) evaluated pembro + chemo vs pbo + chemo in previously untreated patients (pts) with locally recurrent inoperable or metastatic TNBC. Pembro + chemo improved the PFS and OS in pts with PD-L1 combined positive score (CPS) ≥10 disease. We present results for patient-reported outcome (PRO) measures among pts with PD-L1 CPS ≥10.

Methods

Pts were randomized 2:1 to pembro 200 mg or pbo Q3W for up to 35 cycles + chemo (investigator’s choice of nab-paclitaxel, paclitaxel, or gemcitabine/carboplatin). QLQ-C30 (including global health status/quality of life [GHS/QoL]) and physical and emotional functioning scales), QLQ-BR23, and EQ-5D visual analogue scale (VAS) were prespecified. PROs were assessed at baseline, during treatment, and the 30-day safety follow-up visit and analyzed for pts who received ≥1 dose of study treatment and completed ≥1 PRO assessment. Change in PRO scores from baseline were assessed at wk 15 (latest timepoint at which completion/compliance rates were ≥60%/≥80%; negative values favor the pembrolizumab group). Time to deterioration (TTD) in PROs was defined as time to first onset of ≥10-point worsening in score from baseline.

Results

These PRO analyses included 317 pts with PD-L1 CPS ≥10 (pembro + chemo; n = 217; pbo + chemo, n = 100). Completion/compliance at wk 15 was 77.0%/87.0% with pembro + chemo and 70.0%/81.4% with pbo + chemo. There were no between-group differences in change from baseline to wk 15 in the QLQ-C30 GHS/QoL, emotional functioning, physical functioning, or the EQ-5D VAS scale scores, and no between-group difference in TTD in QLQ-C30 GHS/QoL, emotional functioning, or physical functioning (Table). Analyses by QLQ-BR23 showed no decrease in HRQoL with pembro + chemo vs pbo + chemo. Table: 164O

Change from baseline to wk 15a Between-group difference (pembro vs pbo)Least squares mean (95% CI); P value
QLQ-C30 GHS/QoL −1.81 (−6.92 to 3.30); P = 0.4865
QLQ-C30 emotional functioning −1.43 (−7.03 to 4.16); P = 0.6149
QLQ-C30 physical functioning −1.05 (−6.59 to 4.50); P = 0.7102
EQ-5D VAS 0.18 (−5.04 to 5.39); P = 0.9468
TTDb HR (Pembro vs Pbo) (95% CI); P Value
QLQ-C30 GHS/QoL 1.00 (0.72 to 1.40); P = 0.5137
QLQ-C30 emotional functioning 1.28 (0.88 to 1.85); P = 0.9039
QLQ-C30 physical functioning 1.26 (0.90 to 1.77); P = 0.9194

aBased on constrained longitudinal data analysis model (two-sided P value).

bBased on stratified Cox regression model; P value based on stratified log-rank test (one-sided).

Conclusions

Addition of pembro to chemo did not result in a decrease in HRQoL in pts with previously untreated, PD-L1–positive (CPS ≥10) advanced, TNBC.
