Best objective response was assessed according to Response Evaluation Criteria in Solid Tumors V.1.1.
*ORs and p values were determined utilizing two-sided Fisher’s exact test comparing PD versus SD/PR/CR.
CR, complete response; MGR, metastatic growth rate; PD, progressive disease; PR, partial response; SD, stable disease.
