Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 36 years
  • All sexes
  • No healthy volunteers
  • Adult

Who may be able to join

  • Diagnosis of thalassemia major as confirmed by laboratory and clinical criteria
  • Participants who are well transfused-maintaining a mean pre-transfusion Hb (hemoglobin) no less than 9 g/dL.
  • Between 18 and 36 years of age.
  • Receiving ongoing chelation therapy with deferoxamine for at least the past five years. Those who have been exposed to deferiprone for
  • ≤ 6 months but not within the last 2 years prior to commencement of this study will be considered eligible to participate.
  • Abnormal heart MRI T2* greater than or equal to 8 ms and < 20 ms.

Who cannot join

  • Have anemia other than thalassemia.
  • HIV antibody positive.
  • Clinical evidence of cardiomyopathy as shown by LV Shortening Fraction < 30 % and/or CMR derived LV (left ventricular) Ejection Fraction < 56 %.
  • Severe/significant arrhythmia, including those who have had atrial fibrillation (participants with occasional ectopic beats and normal echo can be included) or those requiring treatment.
  • Previously discontinued therapy with deferiprone or deferoxamine because of an adverse drug reaction to either chelator.
  • Have received deferiprone in the last five years. However those who have been exposed to deferiprone for ≤ 6 months but not within the last 2 years prior to commencement of this study will be considered eligible to participate.

  • Evidence of abnormal liver function (liver enzymes > 3 times upper limit of normal - entry may be delayed until return to normal).
  • Have disorders associated with neutropenia (ANC < 1.5 x 10^9/L) or thrombocytopenia (platelet count <50 x 10^9/L) in the twelve months prior to start of study medication, except for participants who have been treated with interferon and in whom the ANC has fully recovered. Participants with neutropenia or thrombocytopenia in the last year, which resolved with splenectomy, may be considered for this study.
  • Those who refuse to participate in the screening procedures or who are unable to participate in screening procedures or who are unable to comply with requirements of the protocol.
  • Receiving other investigational products.
  • Those in the opinion of the Investigator, who represent poor medical, psychological or psychiatric risks for whom participation in an investigational trial would be unwise.

About this study

Official title: Randomized Trial Comparing the Relative Efficacy of Deferiprone to That of Deferoxamine in Removing Excess Cardiac Iron in Thalassemia Major Patients

The purpose of this study is to determine whether deferiprone has superior efficacy in removing excess iron from the heart when compared with deferoxamine.

Read the detailed description

This study is a multi-center, randomized, open-label, controlled clinical trial. The study population is participants with thalassemia major who are receiving regular chelation therapy with deferoxamine. A total of sixty (60) participants will be enrolled among the investigative sites.

The primary objective of this study is to determine whether deferiprone exhibits superior efficacy in removing excess iron from the heart compared to that of the standard therapy, deferoxamine.

The secondary objective is to evaluate the relative efficacy of deferiprone with respect to that of deferoxamine as assessed by serum ferritin concentration and liver iron concentration.

The primary efficacy measure in this study will be the participants' cardiac iron status, as determined by heart MRI T2* assessments.

The secondary efficacy measure will be by serum ferritin concentration and liver iron concentration. This will be measured by the Superconducting Quantum-Interference Device (SQUID) BioSusceptometer.

The duration of treatment is 12 months.

What participants receive

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

  • Ferriprox (deferiprone)Drug

  • Desferal (deferoxamine)Drug

What is being measured

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

  1. To determine whether deferiprone exhibits superior efficacy in removing excess iron from the heart compared to that of deferoxamine, as reflected by MRI T2* assessments in the heart in participants treated with either chelator

Secondary outcomes (1)
  1. To evaluate the relative efficacy of deferiprone with respect to that of deferoxamine as assessed by serum ferritin concentration and liver iron concentration (LIC)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ferriprox (deferiprone) and Desferal (deferoxamine) in people with Thalassemia Major and Hemosiderosis, run by ApoPharma at 4 sites in 2 countries.

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 9 inclusion and 17 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 5 Jan 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Greece, Italy. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

To determine whether deferiprone exhibits superior efficacy in removing excess iron from the heart compared to that of deferoxamine, as reflected by MRI T2* assessments in the heart in participants treated with either chelator. 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 5 Jan 2016.
