Study information

Scientific title

A single-centre, prospective, randomised, phase III clinical study to evaluate the efficacy and safety indicators of two different iron chelators in patients with iron overload

Acronym

QuelaFer

Study hypothesis

The main aim of this study is to evaluate the efficacy of Deferasirox versus Deferoxamine in reducing serum ferritin levels and iron liver deposits in iron overload patients.

Excess iron in blood and tissues causes irreversible tissue damage. The removal of excess iron as response to treatment positively influences on the survival of patients with overload. Currently, there are two types of iron chelating agents authorised, each one with different route of administration (Deferoxamine-parenteral and Deferasirox-oral) but the superiority of one over another is not defined in relation to the intensity of the response, time to be reached or the severity and frequency of associated adverse effects or its impact on quality of life.

Condition

Haemosiderosis

Intervention

1. Group A: Deferasirox 20 mg/kg/day oral capsules for 4 months
2. Group B: Desferoxamine 30 mg/kg/day, slow Subcutaneous (SC) infusion administered over 8 hours by a portable infusion pump 3 times/week for 4 months
3. Patients from both groups will be followed for 1-month period.
4. The following tests should be performed:
4.1. Peripheral blood creatinine (weekly in the 1st month and then monthly), serum transaminases, bilirubin and alkaline phosphatase (on day 1 of treatment, every 2 weeks in the 1st month, then monthly, and at the end of treatment)
4.2. Serum ferritin (at screening, at baseline and at the beginning of each month of treatment)
4.3. Liver magnetic resonance imaging (MRI) and quantification of tissue iron (at screening visit and at the end of 4 months of treatment)
4.4. Computerised tomography (CT), CCL18 and proBNP activity (at screening, before the 2nd month of treatment and after treatment)
4.5. Eastern Cooperative Oncology Group (ECOG) performance status (at screening, and on day 1 of each new cycle of treatment)
4.6. Electrocardiogram (at screening and whenever the investigator deems it appropriate, SF36 quality of life questionnaire (at screening, before the 2nd month of treatment and after treatment).

Phase III

Drug names

1. Deferoxamine
2. Deferasirox

Primary outcome measures

Treatment efficacy was determined by measuring the serum ferritin at screening, at baseline and at the beginning of each month of treatment

Secondary outcome measures

1. Identify whether blood biomarkers of macrophage activation (chitotriosidase, CCL-18) are higher in patients with iron overload than in the population with normal serum ferritin levels stratified by age and sex and if they can be used as markers of response to chelation therapy
2. To study if the biomarkers concentration correlates with the serum ferritin level, liver MRI, cardiac function assessed by ultrasound and its own changes after 4-month treatment with iron chelators
3.To assess the quality of life of patients undergoing both these treatments
