  Serious Adverse Events


  Other Adverse Events


  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Overall survival results are confounded by the fact that 85% of the participants initially randomized to placebo switched to open-label regorafenib.
