Clinical Trial: Study Of Efficacy,Safety of Combined Deferasirox and Deferiprone Versus Combined Deferiprone and Desferal In Conditions of Iron Overload

Study Status: Completed
Recruit Status: Unknown status
Study Type: Interventional

Official Title: A Prospective Randomized Comparative Study of Efficacy and Safety of Combined Deferiprone (DFP) and Deferasirox Versus DFP and Desferrioxamine (DFO) Therapy in Diseases With Severe Iron Overload

Brief Summary:

Interventional Allocation: Randomized Endpoint Classification: Safety/Efficacy Study of combined chelation therapy Masking: Open Label Primary Purpose: Treatment of transfusional iron overload

Primary Outcome Measures:

• The primary outcome measure is to assess efficacy in lowering serum ferritin level(the change in serum ferritin compared to baseline) with combining DFP and deferasirox compared to combined DFP and DFO in conditions with severe chronic iron overload; showing an up-trend of SF over previous 12 months on single chelator.

Secondary Outcome Measures:

• The secondary outcome measure is to determine the number of patients who will develop adverse events in order to assess safety upon administering the drugs in combination (DFP and DFX) compared to the combination of DFO and DFP.


Detailed Summary:

Study population:

  1. Beta-thalassemia major patients; Patients with high iron stores Serum ferritin consistently > 2500 mcg/l and or increasing trend over previous 12 months Liver iron >14 mg/g dry weight- by R2 MRI
  2. Other causes of transfusional hemosiderosis

Estimated Enrollment: 30 patients in each arm Study Start Date: January 1st ; 2011 enrollment period 8 weeks Estimated Study Completion Date: End of February 1212

Arms Assigned Interventions

Arm 1: Patients will be treated with combined DFP and deferasirox. Drug: Ferriprox It will be given orally in the morning Other Name: DFP Initial dose 25/mg/kg in 3 divided doses (better tolerated if started and then built up over 4 weeks).

Dose may be increased up to 100mg/kg/day guided by serum ferritin. Agranulocytosis risk 1-2%. Monitor TLC and granulocytic count / 2weeks. Patients need to be continually educated about this risk, know that they must stop DFP if they have a fever or infection.

Drug: Deferasirox will be orally administered at a dose of 20 mg/kg once daily at evening for 5 days.

Other Name: ICL670 Arm 2: Patients will be treated for 6 days with a combination of deferoxamine and DFP.

Interventions:

  • Drug: Deferoxamine
  • Drug: DFP Drug: Deferoxamine Deferoxamine will be administered subcutaneously over 8 hours for 5 days at a dose of 40 mg/kg.

• The primary outcome measure is to measure the change in serum ferritin level from baseline in the 2 combination therapy.



Original Primary Outcome: Same as current

Current Secondary Outcome: to determine the safety upon administering the drugs in combination (DFP and DFX) compared to the combination of DFO and DFP. [ Time Frame: 12 months ]

• The secondary outcome measure is to determine the number of patients who will develop adverse reactions upon administering the drugs in combination.


Original Secondary Outcome: Same as current
