About this study
Official title: An Open-label Safety Study of S-888711 in Adult Subjects With Relapsed Persistent or Chronic Immune Thrombocytopenia With or Without Prior Splenectomy
The primary objective of this study was to assess the long-term safety of lusutrombopag in the treatment of adults with relapsed persistent or chronic ITP with or without prior splenectomy.
Read the detailed description
This was an open-label, long-term safety study of lusutrombopag in the treatment of adults with relapsed persistent or chronic ITP with or without prior splenectomy. Patients who participate in this study must have completed the Phase 2 study 0913M0621 (NCT01054443), a double-blind, placebo controlled, parallel group study that evaluated the efficacy and safety lusutrombopag during which they either completed treatment or discontinued treatment due to a platelet count > 400,000/μL.

tablet
| Study group | Role | What they receive |
|---|---|---|
| Lusutrombopag | Experimental | Participants received lusutrombopag 0.5 mg administered orally once a day for up to 3 years or until study termination. The dose was adjusted based on platelet counts. If a subject's platelet count remained < 50,000/μL, the dose could have been increased by 0.25 mg up to a maximum dose of 2.0 mg. Receives: Drug: Lusutrombopag |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With Adverse Events
An AE is defined as any untoward medical occurrence in a subject administered a pharmaceutical product during the course of a clinical investigation, including any unfavorable and unintended sign, symptom, or disease temporally associated with the use of an investigational product (IP), whether or not thought to be related to the IP. AEs reported after initial study drug administration were considered treatment-emergent.
A serious adverse event is defined as any AE that resulted in death, was life-threatening, hospitalization or prolongation of existing hospitalization, a persistent or significant disability/incapacity, or a congenital anomaly/birth defect or an important medical event that, based upon medical judgment, may jeopardize the participant or require medical or surgical intervention to prevent one of the outcomes listed above.
A treatment-related AE is any AE determined by the investigator to be possibly related, probably related, or definitely related to study drug.
Measured: From first dose of study drug in the extension study up to 6 weeks after last dose; median (range) time on study treatment was 148 (10-387) days.
Secondary outcomes (5)
Duration of Response
Duration of response was defined as the percentage of the cumulative time a platelet count was ≥ 50,000 cells/µL during the extension study.
Measured: From first dose of study drug in the extension study up to 6 weeks after last dose; median (range) time on treatment was 148 (10 - 387) days.
Number of Participants With Worst Severity of Bleeding Associated With ITP During the Treatment Period
Bleeding assessments were performed by the Investigator according to the World Health Organization (WHO) criteria bleeding scale:
Grade 0: no bleeding; Grade 1: petechial bleeding; Grade 2: mild blood loss (clinically significant); Grade 3: gross blood loss, requires transfusion (severe); Grade 4: debilitating blood loss, retinal or cerebral associated with fatality.
For each participant, the most severe WHO bleeding grade observed during the treatment period is reported.
Measured: Bleeding assessments were performed at Weeks 1, 2, 3, 4, 5, and 6, Months 1, 2, 3, 6, 9, and 12, and every 3 months thereafter until end of treatment; median (range) time on treatment was 148 (10-387) days.
Percentage of Participants Who Achieved a Platelet Count of < 50,000 Cells/μL, Between 50,000 to 400,000 Cells/μL, and ≥ 400,000 Cells/μL
This analysis includes platelet counts measured during the treatment period, including while participants were taking rescue medications.
Measured: Platelets were assessed at Weeks 1, 2, 3, 4, 5, and 6, Months 1, 2, 3, 6, 9, and 12, and every 3 months thereafter, until end of treatment; median (range) time on treatment was 148 (10-387) days.
Percentage of Participants Who Achieved a Platelet Count of < 50,000 Cells/μL, Between 50,000 to 400,000 Cells/μL, and ≥ 400,000 Cells/μL Without Rescue Medication
This analysis excludes platelet counts measured while the participant was taking rescue medications and during the 4 weeks after rescue medication.
Measured: Platelets were assessed at Weeks 1, 2, 3, 4, 5, and 6, Months 1, 2, 3, 6, 9, and 12, and every 3 months thereafter, until end of treatment; median (range) time on treatment was 148 (10-387) days.
Change From Baseline in Platelet Counts at the Final Visit
Measured: Baseline and the final visit (If a subject had multiple platelet count measurements for the specific dose level due to dose adjustments, the final platelet count was used)

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Lusutrombopag in people with Immune Thrombocytopenia, run by Shionogi at 19 sites in United States.
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 10 inclusion and 24 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: stopped early, as of the sponsor's last update on 26 Feb 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 19 sites in United States. 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 26 Feb 2021). 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?
Number of Participants With Adverse Events (time frame: From first dose of study drug in the extension study up to 6 weeks after last dose; median (range) time on study treatment was 148 (10-387) days.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 26 Feb 2021; AzTrials last refreshed its copy on 8 Nov 2026.
