CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Efficacy, Safety, Therapy

To assess the safety and tolerability of edoxaban treatment in patients with PSVD

Secondary objectives 4

  1. To assess the preliminary efficacy of edoxaban treatment for the prevention of splanchnic vein thrombosis (SVT) development.
  2. To assess the effects of edoxaban treatment on spleen stiffness as a surrogate of portal hypertension severity measured before and after edoxaban treatment.
  3. To assess the preliminary efficacy of edoxaban treatment for the prevention of hepatic decompensation.
  4. To assess effects of edoxaban treatment on health-related quality of life.
