About this study
Official title: A Multicentre Investigation of Recombinant Human Thrombopoietin (rhTPO) Combining Rituximab Versus High-dose Dexamethasone for Initial Treatment of Primary Immune Thrombocytopenia (ITP)
The project was undertaking by Qilu Hospital of Shandong University and other 13 well-known hospitals in China. In order to report the efficacy and safety of Recombinant Human thrombopoietin combining with Rituximab for the treatment of adults with primary immune thrombocytopenia (ITP), compared to conventional high-dose dexamethasone therapy.
Read the detailed description
The investigators are undertaking a parallel group, multicentre, randomised controlled trial of 240 primary ITP adult patients from 14 medical centers in China. One part of the participants are randomly selected to receive recombinant human thrombopoietin (given subcutaneously at a dose of 300Units/kgfor 14 consecutive days, following with a flexible dosage depending on platelet count until the 28th day), combining with rituximab (given intravenously at a dose of 100 mg weekly for 4 weeks, i.e. Day 1, 8, 15, 22; the others are selected to receive high-dose of dexamethasone treatment (given intravenously at a dose of 40 mg daily for 4 days). Platelet count was evaluated before and after treatment,in order to report the conversion ratio of primary ITP to chronic ITP.

patients in recombination treatment group take Rituximab( intravenously ,100 mg weekly for 4 consecutive weeks); in combination with rhTPO( subcutaneously , 300U/kg for 14 consecutive days,followed by flexible treating dosage so as to keep the platelet count above 50×10^9/L until the 28th day)
DexamethasoneDrug
Patients in single treatment group take dexamethasone intravenously at 40 mg daily for 4 consecutive days.
| Study group | Role | What they receive |
|---|---|---|
| combinant treatment group | Experimental | 120 enrolled patients are randomly picked up to take Rituximab in combination with rhTPO at the indicated dose. Receives: Drug: recombinant human thrombopoietin (rhTPO); rituximab |
| single treatment group | Active comparator | 120 enrolled patients are randomly picked up to take dexamethasone at the indicated dose. Receives: Drug: Dexamethasone |
What is being measured
The primary outcome is the main question the study is designed to answer.
Evaluation of platelet response(Chronic ITP)
Chronic ITP is defined as having platelet count less than 100×10^9/L,lasting for more than 12 months.
Measured: up to 1 year per subject
Evaluation of platelet response (Complete Response)
CR. A complete response (CR) was defined as a sustained (≥ 3 months) platelet count ≥ 100×10^9/L without recurrence of thrombocytopenia
Measured: up to 1 year per subject
Evaluation of platelet response (R)
- A response (R) was defined as a sustained (≥ 3 months) platelet count ≥ 30×10^9/L without recurrence of thrombocytopenia
Measured: up to 1 year per subject

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing recombinant human thrombopoietin (rhTPO); rituximab and Dexamethasone in people with Purpura and Idiopathic Thrombocytopenic Purpura, run by Shandong University at 1 site in China.
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 5 inclusion and 7 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: withdrawn, as of the sponsor's last update on 20 Apr 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. 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 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?
The study was withdrawn before enrolling participants, so there are no results.
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?
Evaluation of platelet response(Chronic ITP) (time frame: up to 1 year per subject). The study lists 3 primary outcomes in all. 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 NCT01734057, which also lists 5 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 20 Apr 2016.
