About this study

Official title: A Multicentre Investigation of Recombinant Human Thrombopoietin (rhTPO) Combining Dexamethasone 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 Dexamethasone for the treatment of adults with primary immune thrombocytopenia (ITP), compared to High-dose Dexamethasone therapy.

Read the detailed description

The investigators are undertaking a parallel group, multicentre, randomised controlled trial of 200 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/kg for7-14 consecutive days, following with a flexible dosage depending on platelet count until the 28th day), combining with dexamethasone (given intravenously at a dose of 40 mg per day for 4days, 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • recombinant human thrombopoietin (rhTPO); dexamethasoneDrug

    Patients in recombination treatment group take 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), in combination with dexamethasone(intravenously , 40mg/d for 4 consecutive days)

  • DexamethasoneDrug

    Patients in single treatment group take dexamethasone intravenously at 40 mg daily for 4 consecutive days.

What is being measured

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

  1. Evaluation of platelet response

    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

  2. Evaluation of platelet response (R)

    1. 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); dexamethasone 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: finished, 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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 (time frame: up to 1 year per subject). The study lists 2 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 NCT01734044, 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.
