  • If taking inhibitors of P glycoprotein (P-gp), except for verapamil, dose must be stable for 7 days prior to Screening
  • Provide written informed consent
  • Willing and able to comply with all aspects of the protocol

Who cannot join

  • Any history of arterial or venous thrombosis, including partial or complete thrombosis
  • Evidence of thrombosis (partial or complete) in the main portal vein, portal vein branches, or any part of the splenic mesenteric system at Screening

  • Hepatic encephalopathy that cannot be effectively treated
  • Participants with HCC with Barcelona Clinic Liver Cancer (BCLC) staging classification C or D

About this study

Official title: A Randomized, Global, Double-blind, Placebo-controlled, Parallel-group Study to Evaluate the Efficacy and Safety of Once-daily Oral Avatrombopag for the Treatment of Adults With Thrombocytopenia Associated With Liver Disease Prior to an Elective Procedure

This is a global, multicenter, randomized, double-blind, placebo-controlled, parallel group study using avatrombopag to treat adults with thrombocytopenia associated with liver disease. The study will evaluate avatrombopag in the treatment of thrombocytopenia associated with liver disease prior to an elective procedure to reduce the need for platelet transfusions or any rescue procedure for bleeding due to procedural and post-procedural bleeding complications. Participants will be enrolled into 2 cohorts according to mean baseline platelet count and, within each baseline platelet count cohort will be further stratified by risk of bleeding associated with the elective procedure (low, moderate, or high) and hepatocellular carcinoma (HCC) status (Yes or No).

Read the detailed description

This study will consist of 3 phases: Prerandomization, Randomization, and a Follow-up Phase. The Prerandomization Phase includes one Screening Visit that will take place from Day -14 through Day -1; the Randomization Phase includes the Baseline Period, Treatment Period, and Procedure Day Period (5 to 8 days after last dose of study drug [Study Day 10 to 13]). The Follow-up Phase comprises 2 visits: 7 days post Procedure Day and 30 days after receiving the last dose of study drug. Permitted procedures include: Paracentesis; Thoracentesis; Gastrointestinal endoscopy with or without plans for biopsy, colonoscopy, polypectomy, or variceal banding; Liver biopsy; Bronchoscopy with or without plans for biopsy; Ethanol ablation therapy or chemoembolization for HCC; Vascular catheterization (including right side procedures in participants with pulmonary hypertension); Transjugular intrahepatic portosystemic shunt; Dental procedures; Renal biopsy; Biliary interventions; Nephrostomy tube placement; Radiofrequency ablation; and Laparoscopic interventions.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants Who Did Not Require a Platelet Transfusion After Randomization and up to 7 Days Following a Scheduled Procedure

    Responders were defined as participants who did not require a platelet transfusion or any rescue procedure for bleeding after randomization and up to 7 days following a scheduled procedure. Participants with missing information due to early withdrawal or other reasons were conservatively considered as having received a transfusion in the analysis, (i.e. a Non-responder).

    Measured: Randomization (Visit 2), up to 7 Days following a scheduled procedure

Secondary outcomes (2)
  1. Percentage of Participants Who Achieved a Platelet Count Greater Than or Equal to 50 x 10^9/L on Scheduled Procedure Day

    Responders were defined as participants who achieved a platelet count greater than or equal to 50 x 10^9/L on the procedure day. Participants missing a platelet count on the procedure day were conservatively considered as not achieving a platelet count of 50x10^9/L in the analysis, (i.e. Non-responders).

    Measured: Day 10 to Day 13 (Visit 4)

  2. Change From Baseline in Platelet Counts on Scheduled Procedure Day

    Last observation carried forward was used for participants with a missing platelet count on the scheduled procedure day. Platelet count was measured preprocedure and before any platelet transfusion.

    Measured: Baseline (Visit 2) to Procedure Day 10 to Day 13 (Visit 4)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing avatrombopag (lower baseline platelet count) and avatrombopag (higher baseline platelet count) in people with Thrombocytopenia Associated With Liver Disease, run by Eisai Inc. at 120 sites in 17 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 27 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 27 Feb 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 120 sites in United States, Japan, China, Germany, Israel and 12 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 27 Feb 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of Participants Who Did Not Require a Platelet Transfusion After Randomization and up to 7 Days Following a Scheduled Procedure (time frame: Randomization (Visit 2), up to 7 Days following a scheduled procedure). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01976104, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Feb 2018.
