A Study to Test the Non-Inferiority of Ferric Bepectate IV Against Ferric Carboxymaltose in Patients With Iron Deficiency Anemia

Official title

A Multicentre, Prospective, Randomized, Active-Controlled, Open-Label, Phase III Study to Test the Non-Inferiority of Intravenous Injection of Ferric Bepectate IV Injection Compared to Ferric Carboxymaltose for Treatment of Patients With Iron Deficiency Anaemia (IDA)

Overview

The goal of this clinical trial is to see if a new intravenous iron formulation (Ferric Bepectate IV Injection) can treat adult patients with iron deficiency anemia (IDA) by increasing blood hemoglobin (Hb) as an established formulation (Ferric carboxymaltose). It will also learn about the safety of Ferric Bepectate IV Injection. The main questions it aims to answer are: * Does hemoglobin increase by the same amount 6 weeks after each treatment? * What medical problems do participants have when being treated with the drug? Researchers will compare single dose treatment plans of Ferric Bepectate to double dose treatment plans of both Ferric Bepectate and Ferric carboxymaltose. Participants and researchers will know which drug they are being provided (open-label). Participants will visit the clinic 5 times over 6 weeks for checkups, blood tests and questionaries. The first two visits will be seven days apart and include the two doses of iron treatment.

Detailed description

Iron is essential for the normal functioning of a human body. Iron deficiency anemia (IDA) occurs when blood lacks adequate healthy red blood cells, preventing adequate distribution of oxygen throughout the tissue of the body.

IDA, if left uncorrected, may result in complications such as extreme fatigue, weakness, chest pain, shortness of breath, irregular heartbeats or even heart failure in some cases, in addition to reducing the overall quality of life of a patient. Iron supplementation can effectively treat IDA. An iron-rich diet is known to enhance iron levels, however supplementation is limited by the bio-availability of iron compounds. Oral iron treatment is the most common form of therapy for iron supplementation. However, oral iron supplementation is not ideal for all patients, as adverse events are common, and some patients also fail to respond. Common adverse events (AEs) include significant gastrointestinal discomfort, metallic taste and staining of teeth, resulting in patience discontinuing the treatment. Intravenous (i.v) iron therapy is regarded as a safe method to correct anemia resulting from several conditions that avoids many of the gastrointestinal AEs common with oral iron supplementation.

Ferric carboxymaltose is an established i.v iron formulation approved to treat IDA in Europe and USA. In patients with high iron need, ferric carboxymaltose requires at least two injections, at least 7 days apart. A new i.v. iron formulation has been developed, Ferric Bepectate IV Injection. Ferric Bepectate IV Injection has the potential to be dosed at higher volumes compared to other i.v. iron formulations, allowing for patients with high iron needs to only undergo a single infusion, reducing the medical burden on both the patient and the medical system, and providing a rapid improvement to IDA and associated symptoms.

The current phase 3 study aims to compare Ferric Bepectate IV Injection with two Ferric carboxymaltose formulations (comparators: Ferinject® and Injectafer®) to determine non-inferiority between the Ferric Bepectate IV Injection single dose administration and the current approved dosing for the comparators. A comparison between treatments of the change of hemoglobin (Hb) from baseline after 6 weeks will be the primary outcome. Safety of each treatment will also be assessed to determine superiority, by examining the number of adverse events in the 2 hour period following the beginning of infusion. Key secondary safety endpoints will assess the difference in volume-corrected urine iron after i.v administration, and incidence of hypophosphatemia during the 6 week follow-up period.

A two-dose administration of Ferric Bepectate IV Injection will also be assessed to compare efficacy, tolerance, and safety with the single-dose administration and the comparators.
