What is being measured

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

  1. Change From Baseline in Platelet Counts on Day 15

    Platelet counts were measured by blood draw. Change from Baseline was calculated as the Day 15 value minus the Baseline value.

    Measured: Baseline, Day 15

Secondary outcomes (16)
  1. Analysis of Covariance for Three Patterns of Dose Response Using the Change From Baseline in Platelet Counts (Baseline Platelet Counts as Covariate)

    Exploratory analysis was conducted to see a dose response/trend when a dose goes high with the changes from baseline in platelet counts (12.5 mg, 25 mg, and 37.5 mg) on Day 15 of each subject. The data were analyzed with baseline of platelet counts as covariate for the following dose response pattern using contrast: (1) linearity, (2) saturation at the medium dose, (3) onset of response at the high dose.

    Measured: Baseline, Day 15

  2. Analysis of Covariance for Three Patterns of Dose Response Using the Change From Baseline in Platelet Counts (Baseline of Platelet Counts and Child-Pugh Class as Covariates)

    Exploratory analysis was conducted to see a dose response/trend when a dose goes high with the changes from baseline in platelet counts (12.5 mg, 25 mg, and 37.5 mg) on Day 15 of each subject. The data were analyzed with baseline of platelet counts and Child-Pugh class as covariate for the following dose response pattern using contrast: (1) linearity, (2) saturation at the medium dose, (3) onset of response at the high dose.

    Measured: Baseline, Day 15

  3. Percent Change From Baseline in Platelet Counts on Day 15

    Platelet counts were measured by blood draw. Change from Baseline was calculated as the Day 15 value minus the Baseline value.

    Measured: Baseline, Day 15

  4. Platelet Counts by Treatment Visit

    Platelet counts were measured by blood draw. The Final Assessment Point is the last visit during the treatment period, which is Day 15 or Day 22.

    Measured: Day 1 (Baseline), Day 8, Day 15, and Final Assessment Point (Day 15 or Day 22)

  5. Platelet Counts by Post-Treatment Visit

    Platelet counts were measured by blood draw.

    Measured: 4 days post-treatment, 8 days post-treatment, and 15 days post-treatment

  6. Platelet Counts at Day 22

    Platelet counts were measured by blood draw. The Final Assessment Point is the last visit during the treatment period, which is Day 15 or Day 22.

    Measured: Day 22

  7. Change From Baseline in Platelet Counts by Treatment Visit

    Platelet counts were measured by blood draw. The Final Assessment Point is the last visit during the treatment period, which is Day 15 or Day 22. Change from Baseline was calculated as the value at each visit minus the Baseline value.

    Measured: Baseline, Day 8, Day 15, and Final Assessment Point (Day 15 or Day 22)

  8. Change From Baseline in Platelet Counts by Post-Treatment Visit

    Platelet counts were measured by blood draw. Change from Baseline was calculated as the value at each visit minus the Baseline value.

    Measured: 4 days post-treatment, 8 days post-treatment, and 15 days post-treatment

  9. Percentage of Responders on Day 15

    A responder was defined as a participant with a platelet count within the target range (>=80 x 10^9/Liter) on Day 15.

    Measured: Day 15

  10. Percentage of Responders on Day 22

    A responder was defined as a participant with a platelet count within the target range (>=80 x 10^9/Liter) on Day 22 after receiving eltrombopag for an additional week from Day 15, on which his or her platelet count was <80 x 10^9/Liter.

    Measured: Day 22

  11. Change From Baseline in Platelet Counts on Day 15 by Child-Pugh Class

    Change from Baseline was calculated as the Day 15 value minus the Baseline value. The Child-Pugh (CP) score (ranging from 5 to 15, with 5 being mild and 15 being severe), calculated based on total bilirubin, serum albumin, international normalized ratio, ascites, and hepatic encephalopathy, is used to assess the severity of liver disease. A CP score of 5 or 6 is classified as Class A (mild), a score of 7-9 is classified as Class B (moderate), and a score >=10 is classified as Class C (severe). Participants with a CP score <10 were enrolled in the study.

    Measured: Baseline, Day 15

  12. Change From Baseline in Platelet Counts on Day 15 by Sex

    Change from Baseline was calculated as the Day 15 value minus the Baseline value. The numbers of females and males in each treatment group are illustrated by the "n's" in the category titles.

    Measured: Baseline, Day 15

  13. Change From Baseline in Platelet Counts on Day 15 by Age

    Change from Baseline was calculated as the Day 15 value minus the Baseline value. The numbers of participants in each age category are illustrated by the "n's" in the category titles.

    Measured: Baseline, Day 15

  14. Log-transformed Cmax on Days 14 and 15 in Participants Receiving Eltrombopag 12.5 mg

    Serial PK samples were collected over a 24-hour (h) period on Days 14 and 15 in participants receiving eltrombopag 12.5 mg. A total of 8 blood samples (3 milliliters per sample) were collected at pre-dose, and at 1 h, 2 h, 4 h, 6 h, 8 h, 10 h, and 24 h post-dose. Cmax=maximum drug concentration.

    Measured: Day 14, Day 15

  15. Log-transformed Tmax on Days 14 and 15 in Participants Receiving Eltrombopag 12.5 mg

    Serial PK samples were collected over a 24-hour (h) period on Days 14 and 15 in participants receiving eltrombopag 12.5 mg. A total of 8 blood samples (3 milliliters per sample) were collected at pre-dose, and at 1 h, 2 h, 4 h, 6 h, 8 h, 10 h, and 24 h post-dose. Tmax=maximum drug concentration time.

    Measured: Day 14, Day 15

  16. Log-transformed AUC(0-t) and AUC(0-24) on Days 14 and 15 in Participants Receiving Eltrombopag 12.5 mg

    Serial PK samples were collected over a 24-hour (h) period on Days 14 and 15 in participants receiving eltrombopag 12.5 mg. A total of 8 blood samples (3 milliliters per sample) were collected at pre-dose, and at 1 h, 2 h, 4 h, 6 h, 8 h, 10 h, and 24 h post-dose. AUC(0-t)=area under the concentration-time curve from time zero (pre-dose) to last time of quantifiable concentration, and AUC(0-24)=area under the concentration-time curve from 0 (pre-dose) to 24 hours.

    Measured: Day 14, Day 15

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing eltrombopag 12.5 milligrams (mg) tablet and eltrombopag 25 mg tablet in people with Liver Diseases, run by GlaxoSmithKline at 10 sites in Japan.

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 19 inclusion and 22 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 12 May 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in Japan. 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. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 23 Sep 2010). 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?

Change From Baseline in Platelet Counts on Day 15 (time frame: Baseline, Day 15). 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 NCT00861601, which also lists 1 linked publication.

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 12 May 2015.
