Brief Summary:
The objective of this study is to evaluate the pharmacokinetics of deferiprone and its 3-O-glucuronide metabolite following administration of a single 1500 mg dose of Ferriprox in patients with sickle cell disease.

Condition or disease Intervention/treatment Phase
Sickle Cell Disease Drug: single 1500 mg dose of Ferriprox Phase 1

Detailed Description:
This is a single-arm, single-dose study of Ferriprox in patients with sickle cell disease. Patients found to be eligible will visit the clinic the day before receiving the drug, in order to reconfirm eligibility and to undergo baseline assessments, and will receive a single dose of 1500 mg Ferriprox under fasting conditions. Blood and urine samples for pharmacokinetic assessment will be collected over a 10-hour period. Standard safety assessments will be performed throughout the study, and patients will return for a safety follow-up.

Outcome Measures

Primary Outcome Measures :
  1. Cmax for Serum Deferiprone and Deferiprone 3-O-glucuronide [ Time Frame: 10-hour interval ]
    Cmax (maximum measured serum concentration) was assessed over a 10-hour interval for deferiprone and its 3-O-glucuronide metabolite. Blood samples were obtained pre-dose and at 0.25, 0.50, 0.75, 1, 1.33, 1.66, 2, 2.5, 3, 4, 6, 8, and 10 hours post-dose.

  2. Tmax for Deferiprone and Deferiprone 3-O-glucuronide [ Time Frame: 10-hour interval ]

    Tmax (time to the maximum measured serum concentration) was assessed over a 10-hour interval for deferiprone and its 3-O-glucuronide metabolite. Blood samples were obtained pre-dose and at 0.25, 0.50, 0.75, 1, 1.33, 1.66, 2, 2.5, 3, 4, 6, 8, and 10 hours post-dose.

    The results of the Tmax parameter are reported as the median and range (other parameters are reported as mean and standard deviation).


  3. AUC0-∞ for Serum Deferiprone and Deferiprone 3-O-glucuronide [ Time Frame: 10-hour interval ]
    AUC0-∞ (area under the curve, zero to infinity) was assessed over a 10-hour interval for deferiprone and its 3-O-glucuronide metabolite. Blood samples were obtained pre-dose and at 0.25, 0.50, 0.75, 1, 1.33, 1.66, 2, 2.5, 3, 4, 6, 8, and 10 hours post-dose.

  4. T1/2 for Serum Deferiprone and Deferiprone 3-O-glucuronide [ Time Frame: 10-hour interval ]
    T1/2 (apparent terminal elimination half-life) was assessed over a 10-hour interval for deferiprone and its 3-O-glucuronide metabolite. Blood samples were obtained pre-dose and at 0.25, 0.50, 0.75, 1, 1.33, 1.66, 2, 2.5, 3, 4, 6, 8, and 10 hours post-dose.


Secondary Outcome Measures :
  1. Frequency of Adverse Events [ Time Frame: From Day 1 (Dosing) to Day 7 plus/minus 3 days (Follow-up) ]
  2. Frequency of Serious Adverse Events [ Time Frame: From Day 1 (Dosing) to Day 30 post-dose ]

  3. Body weight ≥ 50 kg
  4. Body mass index (BMI) ≥ 18 and ≤ 32 kg/m^2
  5. Absolute neutrophil count (ANC) of >1.5 x 10^9/L
  6. Women of childbearing potential must agree to either be sexually inactive or use an acceptable method of birth control for 14 days prior to dosing and for 30 days afterwards
  7. A fertile heterosexual male must agree that he or his partner will use an effective method of contraception for 14 days prior to dosing and for 30 days afterwards

Exclusion Criteria:

  5. A serious, unstable illness, as judged by the Investigator, within the past 3 months before screening visit including but not limited to hepatic, renal, gastro-enterologic, respiratory, cardiovascular, endocrinologic, neurologic or immunologic disease
  6. Hemodialysis during the week prior to dosing or planned for the day of dosing
  7. Known difficulty in providing blood samples
  8.

  12. Treatment with an investigational drug within the past 30 days or 5 half-lives of that drug (whichever is longer) prior to study drug administration
  13. Pregnant or nursing female
