Response to anti‐PD‐1 antibody

		sPD‐L1 < 90	sPD‐L1 ≥ 90
Response	N = 233	(N = 192)	(N = 41)	P‐value
Complete response	0	0	0
Partial response	56 (24%)	47 (24%)	9 (22%)
Stable disease	69 (30%)	63 (32%)	6 (15%)
Progressive disease	100 (43%)	78 (40%)	22 (54%)
Not evaluable	8 (3%)	4 (2%)	4 (10%)
ORR% (95% CI)	24% (19%–30%)	24% (11%–38%)	22% (19%–31%)	0.731
DCR% (95% CI)	54% (47%–60%)	57% (50%–64%)	37% (22%–53%)	0.0158

The disease control rate was defined as the percentage of patients with a complete or partial response or stable disease.

DCR, disease control rate; ORR, objective response rate; sPD‐L1, soluble programmed death ligand 1.
