Baseline demographic characteristics have been effectively balanced (Table 1). In total, 96 (n=402/417) of patients had distant metastases, most frequently in lung (86 ; n=359/417), lymph nodes (51 ; n=214/417), and bone (27 ; n=113/417). Over 75 of individuals had been good for fluorodeoxyglucose (FDG) uptake on positron emission tomography scintigraphy. Efficacy The study met its main endpoint, showing substantial improvement in PFS for sorafenib compared with placebo (HR, 09; 95 CI, 056; P0001; median 10 vs five months, respectively [Fig. 2a]), having a 41 reduction in the danger of progression or death for the duration of the doubleblind period. Investigatorassessed PFS closely matched the central critique: HR, 09; 95 CI, 091; P0001; median ten (sorafenib) versus 5 (placebo) months. Exploratory subgroup analysis of PFS showed constant improvement in all prespecified subgroups (Fig. 2b). Median time from randomization until final recognized followup was 16.two months (range, 033). There was no statistically important difference in OS (HR, 00; 95 CI, 049;P=04) (Fig. 3a). Median OS had not been reached in the time of major evaluation. A total of 150 (71 ) individuals receiving placebo crossed over to get openlabel sorafenib at progression (Fig. 1). In addition, 42 (20.3 ) individuals in the sorafenib arm and 18 (eight.six ) individuals within the placebo arm received subsequent anticancer therapy following the trial. ORR was 12 (n=24/196) versus 0 (n=1/201) with sorafenib versus placebo, respectively (P0001), all PR. Median duration of response for individuals using a PR to sorafenib was 10 months (95 CI, 76). All round reduction in the sum of target lesions was higher with sorafenib (Fig. 3b). For patients without having PR, SD for 4 weeks was observed in 74 (across both arms; n=294/397), and SD for 6 months (posthoc analysis) in 41 (n=82/196; sorafenib) and 33 (n=67/202; placebo). DCR (PR plus SD six months; posthoc evaluation) was 54 (n=106/196) versus 33 (n=68/201) with sorafenib versus placebo, respectively (P0001). Median TTP was 11 months (95 CI, 94) with sorafenib versus 5 months (95 CI, 5) with placebo (HR, 06; 95 CI, 032; P0001).
