Details and patient eligibility

About

The purpose of this study is to assess Pharmakokinetic properties of iron isomaltoside 1000 (Monofer®) in doses of 100 mg, 200 mg or 500 mg in subjects with Stage 5 Chronic Kidney Disease on Dialysis Therapy (CKD-5D).

Enrollment: 18 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Men and women, aged more than 18 years.
2. Weight above 50 kg.
3. Subjects diagnosed with CKD-5D and on dialysis therapy for at least 90 days prior to inclusion.
4. Serum ferritin ≤ 800 ng/mL.
5. Transferrin Saturation ≤ 35%.
6. Life expectancy beyond 12 months by Principal Investigator's judgement.
7. Hb concentrations ≥10.0 g/dL and ≤12.5 g/dL both at Screening Visit 1a and at Screening Visit 1b (Screening Visit 1a and Visit 1b must be separated by at least 1 week).
8. Erythropoiesis Stimulating Agent (ESA) treatment (to be kept constant during the study period and for 4 weeks prior to inclusion with only one missed dose to be allowed during this pre-entry period).
9. Subjects in maintenance iron therapy with average iron administration ≤ 100 mg/week for 4 weeks prior to inclusion and willingness to switch to investigational product.
10. Willingness and ability to participate after informed consent (including HIPAA, if applicable).

Exclusion criteria

1. Anemia caused primarily by other factors than renal related anemia.
2. Iron overload or disturbances in utilization of iron (e.g. hemochromatosis and hemosiderosis).
3. Difference of Hb ≥ 1.0 g/dL between Screening Visits 1a and 1b.
4. Known hypersensitivity to any excipients in the investigational drug products.
5. Subjects with a history of multiple allergies.
6. Decompensated liver cirrhosis and history of hepatitis B or C [Alanine Aminotransferase (ALT) > 3 times upper limit of normal].
7. Acute or chronic infections (assessed by clinical investigator judgment), supported by White Blood Cells (WBC) and C-Reactive Protein (CRP).
8. Rheumatoid arthritis with symptoms or signs of active joint inflammation.
9. Pregnant or nursing women.
10. Women of child bearing potential who are not using safe contraceptive methods (e.g. intrauterine device, oral contraceptives or surgically sterilized) or who are planning to become pregnant within the study period.
11. Blood transfusion within the previous 12 weeks.
12. Planned elective surgery during the study where significant blood loss is expected.
13. Participation in any other clinical trial within 3 months prior to screening.
14. Untreated Vitamin B12 or folate deficiency.
15. Any other medical condition that, in the opinion of Principal Investigator, may cause the subject to be unsuitable for the completion of the study or place the subject at potential risk from being in the study. Examples include Uncontrolled Hypertension, Unstable Ischemic Heart Disease or Uncontrolled Diabetes Mellitus.
