About this study
Official title: Therapy of Adults Affected by Idiopathic Thrombocytopenic Purpura With 3 Cycles Pulses of High-dose Dexamethasone (HD-DXM)
In this prospective, randomized, controlled clinical trial investigators' aim was to compare the efficacy and the adverse effect of 3 therapy cycles of HD-DXM versus conventional treatment with PDN for untreated adult patients with ITP. In this study standardized criteria and definitions were used according to consensus international working group guideline for ITPto compare clinical outcomes of the two corticosteroid treatment regimens and determine the superior regimen as a first line strategy for new primary ITP in adults

Therapy of Adults affected by idiopathic thrombocytopenic purpura with 3 cycles pulses of high-dose dexamethasone (HD-DXM): a prospective randomized clinical trial Alireza Sadeghi, Saeid Rezaei Jouzdani, Forough Hosseini
Introduction :
Idiopathic thrombocytopenic purpura(ITP) is an autoimmune disorder characterized by platelet destruction leading to decreased platelet count and an increased risk of bleeding. Mechanisms including autoantibody- mediated platelet destruction, cytotoxic T-lymphocyte platelet lysis, impaired platelet maturation and production has been identified in the pathogenesis of ITP.(1)The first line treatment of ITP is still corticosteroid therapy. Prednisone(PDN) is the standard corticosteroid therapy in ITP practical guideline usually given at 1 mg/kg per day for 4 weeks and then tapered.(2) Recent studies suggested pulsed high-dose dexamethasone given at a dose 40 mg/day to a 4-day course treatment as an alternative corticosteroid instead of prednisone to reduce the duration and the adverse effect of corticosteroid therapy.(3-5) A multicenter randomized clinical trial compared the 2 corticosteroid therapy and suggested that HD-DXM has more effective and better tolerance than PDN.(4) Another multicenter cohort study using repeated courses of HD-DXM (from 6 to 4 cycles, repeated each cycle 28 days to 14 days interval) confirmed the benefit as compared with conventional therapy and proposed as a first-line treatment for patients with ITP. Also there was no difference in overall response rate between the third and the fourth cycles of HD-DXM pulses therapy, using 3 therapy cycles with 14 days interval between each cycle, has been proposed for better safety and efficacy.(5) In this prospective, randomized, controlled clinical trial investigators' aim was to compare the efficacy and the adverse effect of 3 therapy cycles of HD-DXM versus conventional treatment with PDN for untreated adult patients with ITP. In this study standardized criteria and definitions were used according to consensus international working group guideline for ITP(6) to compare clinical outcomes of the two corticosteroid treatment regimens and determine the superior regimen as a first line strategy for new primary ITP in adults.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
High dose Dexamethasone pulsesDrug
In HD-DXM arm, DXM was administered intravenously at 40 mg in 500cc normal saline (0.9% saline) during 1 hour for consecutive 4 days and then stopped. This cycle was repeated in 14 days interval to receive 3 cycles of treatment.
PrednisoneDrug
Patients in PDN arm received PDN orally at 1.0 mg/kg body weight daily for 4 consecutive weeks. After achieving responses the medication tapered gradually to less than 15mg daily or terminated over 4-6 weeks aimed at maintaining platelet count over 30 ×109/L.
| Study group | Role | What they receive |
|---|---|---|
| Conventional Prednisone receiving group | Active comparator | Patients in PDN arm received PDN Receives: Drug: Prednisone |
| Dxamethasone receiving group | Active comparator | In HD-DXM arm, DXM was administered Receives: Drug: High dose Dexamethasone pulses |

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing High dose Dexamethasone pulses and Prednisone in people with ITP and Croticosteroid Therapy, run by Isfahan University of Medical Sciences at 1 site in Iran.
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 1 inclusion and 1 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 18 Sep 2017. 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 Iran. 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 combined 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.
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?
platelet count (time frame: 6-12 months). 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 NCT02914054, which also lists 6 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 18 Sep 2017.
