Patients (n=350) enrolled in the TIVO-3 study were randomized 1:1 to receive either FOTIVDA or sorafenib. The main efficacy outcome measure was progression-free survival (PFS), assessed by a blinded independent radiology review committee. Other efficacy endpoints were overall survival (OS) and objective response rate (ORR).

Median PFS was 5.6 months (95% CI: 4.8, 7.3) in the FOTIVDA arm (n=175) compared with 3.9 months (95% CI: 3.7, 5.6) for those treated with sorafenib (HR 0.73; 95% CI: 0.56, 0.95; p=0.016). Median OS was 16.4 (95% CI: 13.4, 21.9) and 19.2 months (95% CI: 14.9, 24.2), for the FOTIVDA and sorafenib arms, respectively (HR 0.97; 95% CI: 0.75, 1.24). The ORR was 18% (95% CI: 12%, 24%) for the FOTIVDA arm and 8% (95% CI: 4%, 13%) for the sorafenib arm.

So the PFS & ORR were better than Sorafenib but the OS was worse. Why the big jump?
