Treatment Responses

	mRECIST			RECIST 1.1
Treatment Response	Rego-Sintilimab Group (N=58)	Regorafenib Group (N=55)	P value	Rego-Sintilimab Group (N=58)	Regorafenib Group (N=55)	P value
CR	2	0		0	0
PR	19	9		14	5
SD	22	22		29	25
PD	15	24		15	25
ORR, %	36.2	16.4	0.017	24.1	9.1	0.033
DCR, %	74.1	56.4	0.047	74.1	54.5	0.029

Notes: Objective response rate (ORR) = (CR + PR)/N, and disease control rate (DCR) = (CR + PR + SD)/N, where CR is number of patients with complete response, PR is number of patients with partial response, SD is number of patients with stable disease, and N is total number of patients.

Abbreviations: PD, progressive disease; rego-sintilimab, regorafenib combined with sintilimab; RESICT, response evaluation criteria in solid tumors; mRESICT, modified response evaluation criteria in solid tumors.
