Intravenous Ferric Carboxymaltose vs. Oral Iron Substitution in Patients With Metastatic Colorectal Cancer (CRC) and Iron Deficiency Anemia: a Randomized Multicenter Treatment Optimization Study.

• Status: Completed
• Trial end date: 2020-08-01
• Target enrollment: 0
• Participant gender: All

Summary

Iron deficiency has a high prevalence in colorectal cancer patients ranging at ca. 60%. About 70% of these patients suffer from iron deficiency anemia (IDA) which adds both physical and cognitive impediments to an already straining chemotherapy. Moreover, a chronic disease like cancer often results in a reduced availability of iron for the body. In clinical practice iron substitution is usually administered orally. Due to low resorption rates, frequent gastric side effects and thus poor patient compliance a parenteral substitution seems to be a better option in terms of efficacy. In the framework of a randomized multicenter clinical trial ('FerInject') a comparison of efficacy parameters of parenteral vs. oral iron substitution will now be conducted in order to identify the best treatment form for clinical practice in oncology. Furthermore detailed quality of life-data (QoL) will be collected in both treatment arms for effect comparison.
