About this study
Official title: Recombinant Human Thrombopoietin (rhTPO) Combining Cyclosporin A Versus Cyclosporin A in Management of Steroid-Resistant/Relapsed Immune Thrombocytopenia （ITP）
The project was undertaking by Qilu Hospital of Shandong University and other 5 well-known hospitals in China. In order to report the efficacy and safety of recombinant human thrombopoietin combining with cyclosporin A for the treatment of adults with refractory immune thrombocytopenia (ITP), compared to cyclosporin A monotherapy.
Read the detailed description
The investigators are undertaking a parallel group, multicenter, randomized controlled trial of 120 steroid-resistant/relapsed ITP adult patients from 6 medical centers in China. One part of the participants are randomly selected to receive recombinant human thrombopoietin (given subcutaneously at a dose of 300 Units/kg for 14 consecutive days, following with a flexible dosage depending on platelet count until the 29th day), combining with cyclosporin A (given orally at a dose of 1.5-2.0mg/kg twice daily for 3 consecutive months, adjusted to maintain serum levels between 200-400 ng/ml and tapered by 50 mg/d per week if patients achieved a complete response). The others are selected to receive cyclosporin A monotherapy (given orally at a dose of 1.5-2.0mg/kg twice daily for 3 consecutive months, adjusted to maintain serum levels between 200-400 ng/ml and tapered by 50 mg/d per week if patients achieved a complete response). Platelet count, bleeding and other symptoms were evaluated before and after treatment. Adverse events are also recorded throughout the study. In order to report the efficacy and safety of the combination therapy compared to cyclosporin A monotherapy for the treatment of adults with steroid-resistant/relapsed ITP.

What is being measured
The primary outcome is the main question the study is designed to answer.
Evaluation of platelet response (Complete Response)
CR. A complete response (CR) was defined as a sustained (≥ 3 months) platelet count ≥ 100×10^9/L
Measured: The time frame is up to 3 months per subject
Evaluation of platelet response (Response)
- A response (R) was defined as a sustained (≥ 3 months) platelet count ≥ 30×10^9/L without recurrence of thrombocytopenia.
Measured: The time frame is up to 3 months per subject
Evaluation of platelet response (No Response)
NR.No response (NR) was defined as platelet count < 30 × 10^9/L or a less than two fold increase in platelet count from baseline or the presence of bleeding. Platelet count must be measured on two occasions more than a day apart.
Measured: The time frame is up to 3 months per subject
Evaluation of platelet response (relapses)
A relapses was defined as platelet count falls below 30×10^9/L or bleeding accrues after achieving R or CR.
Measured: The time frame is up to 3 months per subject
Secondary outcomes (1)

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Cyclosporin A and rhTPO in people with Immune Thrombocytopenia, 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 5 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 (Complete Response) (time frame: The time frame is up to 3 months per subject). The study lists 4 primary outcomes in all. 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 20 Apr 2016.
