About this study

Official title: A Phase 3 Randomised, Double-blind, Placebo-controlled Study to Assess the Safety and Efficacy of S-888711 (Lusutrombopag) for the Treatment of Thrombocytopenia in Patients With Chronic Liver Disease Undergoing Elective Invasive Procedures (L-PLUS 2)

The primary purpose of this study is to compare the efficacy of lusutrombopag with placebo for the treatment of thrombocytopenia in patients with chronic liver disease who are undergoing elective invasive procedures.

Read the detailed description

The study consists of 3 periods: a screening period (up to 28 days prior to randomization), a treatment period of 7 days (Days 1 to 7 during which study drug is to be administered for 4 to 7 days), and a posttreatment period (through 28 days posttreatment).

Once-daily treatment with lusutrombopag 3 mg or placebo is to commence on Day 1 and continue for up to 7 days. Platelet count is to be determined on Days 5, 6, and 7 prior to administration of study drug; if a participant meets the administration stopping criterion (ie, platelet count ≥ 50 × 10⁹/L with an increase of ≥ 20 × 10⁹/L from baseline), no additional dose of study drug is to be administered. The planned invasive procedure is to be performed in the posttreatment period between Days 9 and 14. Platelet count for determination of the need for platelet transfusion is to be determined on or after Day 8, but no more than 2 days prior to the invasive procedure; a platelet transfusion is required if the platelet count is < 50 × 10⁹/L.

What is being measured

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

  1. Percentage of Participants Who Required No Platelet Transfusion Prior to the Primary Invasive Procedure and No Rescue Therapy For Bleeding From Randomization Through 7 Days After the Primary Elective Procedure

    Participants were considered as meeting the primary endpoint if all of the following conditions were satisfied:

    • Required no platelet transfusion from the date of randomization through at least 7 days after the primary invasive procedure
    • Did not receive the following rescue therapy for bleeding from the date of randomization through 7 days after the primary invasive procedure
    • Platelet preparations
    • Other blood preparations, including red blood cells and plasma
    • Volume expanders
    • Underwent an invasive procedure. Participants who received at least one platelet transfusion prior to the primary invasive procedure, received at least one rescue therapy for bleeding from the date of randomization through 7 days after the primary invasive procedure, discontinued from the study before undergoing the primary invasive procedure, or did not undergo an invasive procedure were considered as not meeting the primary endpoint.

    Measured: From Randomization to 7 days after the invasive procedure, up to approximately 21 days.

Secondary outcomes (12)
  1. Percentage of Participants Who Required no Platelet Transfusion During the Study

    Participants who did not undergo the invasive procedure were considered as having received platelet transfusion.

    Measured: From Day 1 to end of the posttreatment period, 35 days.

  2. Percentage of Participants With a Response

    A response was defined as a platelet count of ≥ 50 × 10⁹/L with an increase of ≥ 20 × 10⁹/L from Baseline at any time during the study. Participants who met this response criterion only after platelet transfusion were considered as nonresponders.

    Measured: From Day 1 to the end of the posttreatment period, 35 days.

  3. Duration of Increase in Platelet Count to ≥ 50 × 10⁹/L

    The duration of the increase in platelet count was defined as the number of days during which the platelet count was maintained as ≥ 50 × 10⁹/L.

    Measured: From Day 1 to the end of the posttreatment period, 35 days.

  4. Duration of Increase in Platelet Count to ≥ 50 × 10⁹/L by Platelet Transfusion Status

    The duration of the increase in platelet count was defined as the number of days during which the platelet count was maintained as ≥ 50 × 10⁹/L.

    Measured: From Day 1 to the end of the posttreatment period, 35 days.

  5. Percentage of Participants Who Required Rescue Therapy for Bleeding During the Study

    Participants who received rescue therapy for bleeding events during the study. Platelet preparations, other blood preparations (including red blood cells and plasma), and volume expanders were considered as rescue therapy for bleeding events.

    Measured: From Day 1 to the end of the possttreatment period, 35 days.

  6. Number of Participants With Specified Total Number of Platelet Transfusions

    The number of transfusions administered to each patient were collected over the duration of the trial. The data are presented as the number of patients with the highest total number of transfusions followed by the next highest number of transfusions, etc.

    Measured: From Day 1 to the end of the posttreatment period, 35 days.

  7. Change From Baseline in Platelet Count Over Time

    Measured: Baseline and Days 5, 6, 7, 8, 10, 12, 14, 17, 21, 28, and 35.

  8. Number of Participants With Adverse Events (AEs)

    Measured: From first dose of study drug to 28 days after the last dose, 35 days.

  9. Maximum Plasma Concentration (Cmax) of Lusutrombopag

    Measured: Day 5, predose and 2, 4, 6, 8, 24, and 48 hours post-dose (24 and 48 hours post-dose = Day 6 and Day 7 prior to dose on that day).

  10. Time to Maximum Plasma Concentration (Tmax) of Lusutrombopag

    Measured: Day 5, predose and 2, 4, 6, 8, 24, and 48 hours post-dose (24 and 48 hours post-dose = Day 6 and Day 7 prior to dose on that day).

  11. Area Under the Plasma Concentration-time Curve Over the Dosing Interval τ (AUC0-τ) for Lusutrombopag

    Measured: Day 5, predose and 2, 4, 6, 8, 24, and 48 hours post-dose (24 and 48 hours post-dose = Day 6 and Day 7 prior to dose on that day).

  12. Apparent Total Clearance (CL/F) of Lusutrombopag

    Measured: Day 5, predose and 2, 4, 6, 8, 24, and 48 hours post-dose (24 and 48 hours post-dose = Day 6 and Day 7 prior to dose on that day).

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Lusutrombopag in people with Chronic Liver Disease and Thrombocytopenia, run by Shionogi.

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 9 inclusion and 38 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 30 Oct 2018. Status can change between updates, so confirm with the study contact before making plans.

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 25 Sep 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 Required No Platelet Transfusion Prior to the Primary Invasive Procedure and No Rescue Therapy For Bleeding From Randomization Through 7 Days After the Primary Elective Procedure (time frame: From Randomization to 7 days after the invasive procedure, up to approximately 21 days.). 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 NCT02389621, 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 30 Oct 2018.
