Substantiation De verwachting is dat de PAKSWIL-criteria gehaald zullen worden. In de studie kregen in totaal 468 patiënten sacituzumab govitecan (235 patiënten) of chemotherapie (233 patiënten). De mediane progressie-vrije survival was 5,6 maanden (95% confidence interval [CI], 4.3 to 6.3; 166 events) met sacituzumab govitecan and 1,7 maanden (95% CI, 1.5 to 2.6; 150 events) met chemotherapie (hazard ratio for disease progression or death, 0.41; 95% CI, 0.32 to 0.52; P<0.001). De mediane overall survival was 12,1 maanden (95% CI, 10.7 to 14.0) met sacituzumab govitecan en 6,7 maanden (95% CI, 5.8 to 7.7) met chemotherapie (hazard ratio for death, 0.48; 95% CI, 0.38 to 0.59; P<0.001).
