Recruitment & Eligibility

• Status: Completed
• Sex: All
• Target Recruitment: 482

Inclusion Criteria

1. Male and female HDAA patients undergoing maintenance haemodialysis (two to three haemodialysis sessions per week)
2. Aged 18 - 65 years of age (inclusive) (the upper limit of the age was changed from 60 years according to amendment no 2, dated 12 September 2003), either sex
3. Iron deficiency anaemia defined as:
3.1. Haemoglobin (Hb) equals 11 g/dl
3.2. Serum transferrin saturation (TfS) less than 20% or serum ferritin equals 200 ng/ml (changed according to amendment no 2, dated 12 September 2003)
4. Clinically stable, without a history of admission to hospital due to renal decompensation during the 4 weeks preceding the inclusion date
5. Patients who were being treated with EPO, were to have received this treatment for at least one month prior to inclusion in the study, and had to remain on stable doses during participation in the study
6. Patients voluntarily signed an informed consent form at the screening visit, after being informed of the purpose, aims, benefits and risks of the study
7. Females of childbearing potential had to use reliable forms of contraception (barrier methods, including male and female condoms, and diaphragms [cervical caps] with intravaginal spermicide [including jellies, foams and suppositories], intra-uterine device or hormonal contraceptives) in the study and up to one month after the last dose of the study medication. Non-childbearing potential would include surgically sterilised at least 6 months prior to the study or post-menopausal with no menstrual bleeding for at least 2 years prior to the study.
8. Permanent vascular access appropriate for haemodialysis

Exclusion Criteria

1. Known hypersensitivity to iron polysaccharide complexes and compounds of ferric carboxymaltose
2. Ferritin greater than 500 ng/ml, TfS greater than 50%, Hb less than 6.5 g/dl, serum albumin less than 2.5 g/dl (changed according to amendment no 2, dated 12 September 2003)
3. Vitamin B12 or folic acid deficiency
4. Types of anaemia other than anaemia associated with chronic renal failure and iron deficiency anaemia (especially haemolytic, macrocytic, hypoplastic, or sideroblastic anaemia)
5. Any history or clinical findings of iron storage conditions/disorders such as haemochromatosis
6. Active or acute infection or malignancy
7. Active peptic ulcer, asthma, or rheumatoid arthritis
8. Treatment with an investigational drug within the 30 days prior to enrolment
9. Patients positive for hepatitis B surface antigen (HBsAg), or anti-hepatitis C virus (HCV) (for Romania only there was an addition of '...and evidence for acute hepatitis, i.e. abnormal liver function test [LFT] results' according to amendment no 3, dated 19 December 2003). Justification for performing HBsAg, or anti-HCV tests on patients was that LFTs were closely monitored as a possible sign of iron toxicity. Patients with hepatitis B or C infection were excluded because of difficulties to distinguish changes in liver function due to iron toxicity from symptoms of hepatitis.
10. Active liver disease
11. Significant cardiovascular disease, including myocardial infarction within 6 months prior to study inclusion, congestive heart failure New York Heart Association (NYHA) grade III or IV, or poorly controlled hypertension according to judgement of the investigator
12. Endocrinologic or metabolic disorders that were not controlled according to judgement of the investigator
13. Blood transfusion or treatment with intravenous (i.v.) iron preparations within 4 weeks before inclusion into the study (oral iron was not allowed)
14. Patients who needed a blood transfusion within 2 months of the start of the study
15. Anticipated surgery with the exception of surgery related to vascular access
16. Known history of drug or alcohol abuse
17. Pregnancy or lactation
18. Patients with a body mass index (BMI) higher than 15% above the normal BMI (this criterion was deleted by amendment no 2, dated 12 September 2003)

Study & Design

• Study Type: Interventional
• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Efficacy, assessed by correction of patients iron stores and haemoglobin levels. Treatment responders were defined as patients who exhibited an increase of greater than or equal to 1.0 g/dL Hb from baseline at any point during the study. Haemoglobin was taken at screening and on days 0, 2 weeks, 4 weeks, 6 weeks, 8 weeks and 12 weeks.
