Summary

The purpose of this study is to determine how safe, tolerable and effective the new standardised dosage regimen of FERINJECT® infusions is, compared with a well established intravenous iron treatment.

Detailed description

Anaemia in inflammatory bowel disease is mainly attributed to iron deficiency. The main cause of anaemia in IBD patients is chronic blood loss. This means that the iron storage depot in IBD patients is always low and should be replenished. Oral iron therapy is the first choice in many cases because of its safety and economy. However, in patients with gastrointestinal bleeding, the effectiveness of oral therapy is reduced. Additionally, oral iron preparations are frequently associated with gastrointestinal adverse reactions. According to European Guidelines, the preferred route of iron supplementation in IBD is intravenous. Absolute indications for intravenous iron include severe anaemia (Hb \<10 g/dL). The current study is a part of a programme investigating the efficacy and safety of FERINJECT®, a new formulation of parenteral iron (5% weight per volume iron containing ferric carboxymaltose in a solution of water for injection). The efficacy and safety of FERINJECT® were investigated in a prospective, randomised, controlled study conducted in IBD patients. According to the results of this study, FERINJECT® provides a faster Hb response, a higher increase in iron storage and a better patient tolerance compared to oral preparations. In this study, the iron amount required was calculated according to the Ganzoni formula, where 500 mg is the amount of storage iron. To simplify the treatment and to make the treatment more effective, a new standardised dosage regimen was created. The current study is designed to assess whether this new standardised dosage regimen of i.v. FERINJECT® is as safe and effective as the currently used individually calculated dosage regimen. The efficacy and safety of the new standardised dosage regimen of FERINJECT® will be compared with an already established, well-known treatment of IDA with iron sucrose (VENOFER®). Iron sucrose (VENOFER®) is assessed to be effective and well-tolerated in the treatment of IDA in IBD patients. The study is a phase IIIb, multi-centre, randomised, prospective, open-label, controlled study performed at 83 study centres in 14 European countries. The primary objective of the study is to evaluate the non-inferiority in efficacy of a standardised dosage regimen of FERINJECT® compared to individually calculated dosage regimens of VENOFER® in the correction of IDA in patients with IBD in remission. The secondary objective is to evaluate the safety and tolerability of a standardised correction dose regimen of FERINJECT®. Approximately 420 patients will be randomised (1:1 randomisation) to receive treatment with either a standardised correction dosage regimen of FERINJECT® or individually calculated dosage regimens of VENOFER®. Screening will start between 14 and 7 days before the first infusion is administered. Baseline assessments will be performed on Day 1 before the first infusion. During the screening period, patients will be selected based on eligibility criteria. Patients who meet all of the inclusion criteria and none of the exclusion criteria will undergo baseline assessments at Baseline (Day 1) prior to the first dose of study medication. Patients randomised to the FERINJECT® group will receive between 500 mg and 2000 mg of FERINJECT®, according to their Hb and body weight, in up to 3 infusions. The maximum infused weekly dose of will be 1000 mg. For patients in the VENOFER® group, the individual iron deficit will be calculated per individual using the modified formula of Ganzoni. Patients will receive one infusion of 200 mg of VENOFER® twice a week, up to 11 infusions, depending on their calculated iron deficit. Due to the relatively large doses of iron being administered, patients will be monitored carefully throughout the study for symptoms of iron overload. All patients will return for assessment of efficacy and safety at Weeks 4, 8, and 12. The maximum study duration for a patient is 14 weeks. Patients who are not anaemic at Week 12 will be invited to continue to participate in a maintenance study (FER-IBD-07-MAIN), i.e. a study of FERINJECT® versus placebo to determine if the treatment of iron deficiency can prevent the recurrence of anaemia.

• Ulcerative Colitis

Interventions

Type	Name	Description
DRUG	Ferric carboxymaltose	Dosage form: 5% w/v iron containing 50 mg iron per mL, as sterile solution of FERINJECT® in water for injection. In case of drip infusion FERINJECT® (10 to 20 ml) must be diluted only in sterile 0.9% sodium chloride (max 250 ml) FERINJECT® will be administered via i.v. drip infusion. Minimum administration time 15 minutes Dosage: 500 mg, 1000 mg, 1500 mg, according to patients' Hb and body weight
DRUG	Iron Sucrose	VENOFER® will be administered via i.v. drip infusion, diluted only in sterile 0.9% sodium chloride solution as follows: • 10 mL Venofer® (200 mg iron) in maximum 200 mL sterile 0.9% sodium chloride solution in at least 30 minutes. The first 25 mL of solution should be infused as a test dose over a period of 15 minutes. If no adverse reactions occur, use infusion rate no more than 50 mL in 15 minutes. The individual iron deficit will be calculated using the modified formula of Ganzoni. If the patient's body mass index is \>25, a normalised weight will be used for the calculation of iron deficit. Normalised weight = 25 x height \[m\] x height \[m\]. The calculated cumulative VENOFER® dose is to be rounded up or down to the nearest 200 mg. Patients will receive one 200 mg VENOFER® infusion, twice a week, up to 11 times (max dosage 2200 mg), depending on their calculated iron deficit.
