Five grade 5 events were reported during the study and follow-up period due to disease progression (n = 1, sunitinib 37.5 mg/day Schedule 4/2; n = 2, sunitinib 37.5 mg/day CDD schedule); sepsis (n = 1, sunitinib 37.5 mg/day Schedule 4/2); and acute liver and renal failure secondary to disease progression (n = 1, sunitinib 25 mg/day CDD schedule). None of these events were assessed as related to treatment
