Safety & Efficacy of ICL670 vs. Deferoxamine in Beta-thalassemia Patients With Iron Overload Due to Blood Transfusions

Completed · Phase 3

Conditions studied: Beta-Thalassemia

In brief

The purpose of this study is to deterimine if the new orally active iron chelator, ICL670, is as effective and as safe as deferoxamine in preventing accumulation of iron in the body while a patient is undergoing repeated blood transfusions.

• Liver iron content greater than 2 mg iron/g dw as measured by liver biopsy
• Need for regular transfusions 8 or more times per year

You may not qualify if…

• Documented toxicity to deferoxamine
• Elevated liver enzymes in the year preceeding enrollment
• Active hepatitis B or hepatitis C
• HIV seropositivity
• Elevated serum creatinine or significant proteinuria
• History of nephrotic syndrome
• Uncontrolled systemic hypertension
• Fever and other signs/symptoms of infection within 10 days prior to start of the study
• Presence of clinically relevant cataract or previous history of clinically relevant ocular toxicity related to iron chelation
• Second or third degree AV block, clinically relevant Q-T interval prolongation, or patients requiring digoxin or other drugs that prolong the Q-T interval
• Diseases (cardiovascular, renal, hepatic, etc.)that would prevent the patient from undergoing any of the treatment options
• Psychiatric or additive disorders that would prevent the patient from giving informed consent
• History of drug or alcohol abuse within the 12 months prior to the study
• Pregnant or breast feeding patients
• Patients treated with systemic investigational drugs within 4 weeks or topical investigational drugs within 7 days before the start of the study
• Any surgical or medical condition that might significantly alter the absorption, distribution, metabolism or excretion of any drug, such as gastrointestinal disease or major surgery, renal disease, difficulty voiding or urinary obstruction, or impaired pancreatic function.
• Non-compliant or unreliable patients.
• Patients unable to undergo any study procedures such as the hearing or eye tests, or the liver echocardiography.
• Inability to undergo a liver biopsy.
• Patients that would need a dose of ICL670 less than 125 mg per day.
