What was measured

OS was defined as the time from randomization to death due to any cause.

Analysis population: ITT population included all participants randomized to the experimental (cabozantinib + atezolizumab) arm and control (sorafenib) arm.

Groups in this outcome

Experimental Arm: Cabozantinib + Atezolizumab

Participants received 40 mg cabozantinib oral tablets once daily + 1200 mg IV infusion of atezolizumab once every 3 weeks for up to 38 months.

Control Arm: Sorafenib

Participants received 400 mg sorafenib oral tablets twice daily for up to 38 months.

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
