The purpose of this study is to evaluate the efficacy of once-daily Oral E5501 in subjects with chronic liver diseases and thrombocytopenia prior to elective surgical or diagnostic procedures, to evaluate the safety of short-term administration of E5501 and to evaluate the pharmacokinetics (PK) of E5501.

Condition Intervention Phase
Thrombocytopenia Related to Chronic Liver Disease
Drug: E5501
Drug: Placebo
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Phase 2, Randomized, Multicenter, Placebo-Controlled, Double-Blind, Parallel-Group Study to Evaluate the Efficacy, Safety, and Population Pharmacokinetics of Once-Daily Oral E5501 Tablets Used Up to 7 Days in Subjects With Chronic Liver Diseases and Thrombocytopenia Prior to Elective Surgical or Diagnostic Procedures

Further study details as provided by Eisai Inc.:

Primary Outcome Measures:
  • Proportion of responders (i.e., a responder is defined as a subject having an increase of at least 20,000/mm^3 platelet count from baseline and a platelet count >50,000/mm^3, at least once during Day 4 through Day 8). [ Time Frame: Day 4 through Day 8. ]

Secondary Outcome Measures:
  • Change in platelet count from baseline on Day 8 or at end of treatment; dose-response of E5501 for platelet count elevation; proportion of subjects who achieve a platelet count >75,000/mm^3 on Day 4. [ Time Frame: Day 4 through Day 8. ]
  • Proportion of subjects who achieve a platelet count >100,000/mm^3 on Days 4 and 8 [ Time Frame: Day 4 through Day 8. ]
