About this study
Official title: A Prospective Single Arm Study to Assess the Efficacy and Safety of Deferasirox 20 mg/kg BID in Transfusion Dependent Thalassemia Patients Inadequately Responding to Current Treatment With Doses > 35mg/kg QD (Once a Day).
This is an open label, single arm, and multicenter study. The study will include the following phases. A screening phase which lasts for 4 weeks to determine patient eligibility. This phase will be followed by a 24 week Open label treatment phase. The study treatment is defined as deferasirox 20mg/kg BID 9Twice a day). Serum Ferritin Levels and MRI (Magmetic Resonance Imaging) LIC (Liver Iron Concentration) will be measured to evaluate the response to BID.
Read the detailed description
Study treatment is defined as deferasirox 20 mg/kg BID. The study treatment duration is 24 weeks. After the baseline visit, patient visits will occur weekly during the first month because key safety parameters need to be performed weekly in the first month of treatment and then every 4 weeks thereafter until week 24 End of Treatment (EOT).
Patients will have their first dose of study treatment at Visit 3. Safety assessments are routinely performed including collection of AEs (Adverse Events), SAEs (Serious ADverse Events<, vital signs, physical examination, ECG (Electrocardiograph), hematological and biochemistry assessments.
Patients will continue therapy until intolerable toxicity, patient decision or after 24 weeks treatment duration at which point and End of Treatment (EOT) visit will be performed and the End of Treatment CRF( Case Report Form) will be completed.
30 day Safety follow-up Patients who discontinue study drug before completing the study should be scheduled for a visit as soon as possible, at which time all of the assessments listed for the final visit will be performed. At a minimum, all patients who discontinue study treatment, including those who refuse to return for a final visit, will be contacted for safety evaluations during the 30 days following the last dose of study drug.
All patients must be followed for AEs and SAEs that may have occurred after discontinuation from the study treatment. The safety follow-up visit will take place 30 days after the last dose of study drug.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Deferasirox in people with Focus on Transfusion Dependent Thalassemia Patients Who Are Inadequate Responders to Deferasirox > 35mg/kgQD, run by Novartis Pharmaceuticals.
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 11 inclusion and 13 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 2017. Status can change between updates, so confirm with the study contact before making plans.
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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
Mean relative change in SF (Serum Ferritin) (time frame: Baseline, 24 Weeks). 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 2017.
