Safety and Efficacy Study of Oral Ferric Maltol Compared to Intravenous Iron To Treat Iron Deficiency Anaemia in IBD

Are you eligible to participate in this study?

You may be eligible for this study if you meet the following criteria:

  • Conditions: Iron deficiency anemia | Inflammatory bowel disease | Crohn's Disease
  • Age: Between 18 - 100 Years
  • Gender: Male or Female

All of the following criteria must be met to randomize a subject in the study:

  1. Subjects must be competent to understand the information given in the Independent Ethics Committee (IEC) or Institutional Review Board (IRB) approved informed consent form and must sign and date the informed consent prior to any study mandated procedure
  2. Subjects must be willing and able to comply with study requirements
  3. Age 18 years
  4. Subjects must have a confirmed diagnosis of IBD (endoscopic and/or biopsy)
  5. Subjects must be considered suitable for intravenous iron treatment by the Investigator
  6. Subjects must have iron deficiency anaemia defined by the following criteria:
  7. Hb 8.0 g/dL and 11.0 g/dL for women OR a Hb 8.0 g/dL and 12.0 g/dL for men
  8. AND Ferritin <30ng/ml OR Ferritin <100 ng/ml WITH Transferrin saturation (TSAT) <20%
  9. Female subjects of childbearing potential (including perimenopausal females who have had a menstrual period within 1 year prior to screening) must agree to use a reliable method of contraception until they have completed the study and for at least 4 weeks following their final study visit. Reliable contraception is defined as a method which results in a low failure rate, i.e., less than 1% per year when used consistently and correctly, such as implants, injectables, some intrauterine contraceptive devices (IUDs), complete sexual abstinence, or a vasectomized partner. Oral contraceptive medications are allowed in this study. Female subjects who are surgically sterile (bilateral tubal ligation, bilateral oophorectomy or hysterectomy) or postmenopausal (defined as no menstrual period within 1 year of screening) are also allowed to participate.

A subject who meets any of the following criteria is not eligible for participation in the study.

  1. Subject with anaemia due to any cause other than iron deficiency, including, but not limited to:
  2. Untreated or untreatable severe malabsorption syndrome
  3. Immunosuppressant use. Immunosuppressants are permitted so long as there is no clinical evidence or suspicion of the immunosuppressant contributing to the subject's anaemia or affecting erythropoiesis.

Variations to dosing are permitted at the discretion of the investigator so long as there is no clinical evidence or suspicion of the immunosuppressant contributing to the subject's anaemia or affecting erythropoiesis

2. Subject who has received prior to screening:

  1. Within 8 weeks intramuscular or intravenous (IV) iron or administration of depot iron preparation
  2. Within 2 weeks a blood transfusion
  3. Oral iron supplementation, taken specifically to treat anaemia, within the previous 4 weeks (Over the Counter (OTC) multivitamins containing iron are permitted)
  4. Subjects with active inflammatory bowel disease as defined by a SCCAI score greater than 5 at Screening or a CDAI score greater than 300 in the Screening period (as assessed using the Screening haematocrit (HCT) and CDAI diary card completed by the subject for 7 days prior to planned randomization).
  5. Subjects with known hypersensitivity or allergy to either the active substance or excipients of ferric maltol capsules or ferric carboxymaltose solution for IV administration
  6. Subjects who have had serious adverse reactions to previous doses of ferric carboxymaltose or any other intravenous iron.
  7. Subjects with contraindication for treatment with iron preparations, e.g. hemochromatosis, chronic hemolytic disease, sideroblastic anaemia, thalassemia, or lead intoxication induced anaemia.
  8. Subjects with vitamin B12 or folic acid deficiency as determined by the central laboratory screening results. Subjects may start vitamin B12 or folate replacement and rescreen after at least 2 weeks.
  9. Subjects who are pregnant or breast feeding.
  10. Concomitant medical conditions with significant active bleeding likely to initiate or prolong anaemia.
  11. Participation in any other interventional clinical study within 30 days prior to screening.
  12. Subject with cardiovascular, liver, renal, haematologic, gastrointestinal, immunologic, endocrine, metabolic, or central nervous system disease that, in the opinion of the Investigator, may adversely affect the safety of the subject or severely limit the lifespan of the subject (i.e. unlikely to complete the full duration of the study).
  13. Subject with significant neurologic or psychiatric symptoms resulting in disorientation, memory impairment, or inability to report accurately that might interfere with treatment compliance, study conduct or interpretation of the results (e.g., Alzheimer's disease, schizophrenia or other psychosis, active or current alcohol or drug abuse)
  14. Subject who is an inmate of a psychiatric ward, prison, or other state institution.
  15. Subject who is an Investigator or any other team member involved directly or indirectly in the conduct of the clinical study.
  16. Subjects with severe renal impairment: creatinine clearance <30 mL/min. (Applicable to US sites Only)
