Patient case: 45-year-old female with colon cancer; genetic feature: ERBB2 amplification

Clinical trial: IVICA: Intravenous Iron in Colorectal Cancer Associated Anaemia

Summary: 116 eligible patients with confirmed non-metastatic colorectal adenocarcinoma and anemia will be randomized to receive either oral ferrous sulphate (control) or intravenous ferric carboxymaltose (intervention).
  It is hypothesized that intravenous iron supplementation is more efficacious than oral iron therapy.

Detailed description: Patients who are anemic at the time of operation have been shown to have an increased frequency of complications including wound infection and longer post-operative admissions. Similarly, patients who are anemic at the time of their cancer operation are more likely to require a blood transfusion which may increase the risk of recurrence of the cancer.
  At present, oral iron is often used to treat anemia preoperatively in an attempt to minimize the risk above. This drug is often poorly tolerated due to the side effect profile. Blood transfusions can also be administered but expose the patient to other risks including infection and transfusion associated reactions. In order to overcome these issues, intravenous iron preparations have been developed and have improved in safety.
  This is a multi-center, randomized, open label clinical trial, which looks to investigate the efficacy of intravenous iron is in the treatment of preoperative anemia in colorectal patients. Patients will be randomized to receive intravenous ferric carboxymaltose (treatment group) or oral ferrous sulphate (control). The outcomes reviewed will include the amount and frequency of blood transfusions received, changes in patient blood profiles, patient quality of life scores, operative complications and hospital length of stay. The role of hepcidin as a biomarker of treatment response will also be assessed.
  The primary hypothesis to be tested is that intravenous iron will decrease transfusion rates. To detect a significant clinical difference in blood transfused consistent with previous published data (1 unit), 58 patients will be required in each arm of the study with 90% power (alpha 0.05).
  Randomization will be performed independently to the trial team using a computer generated variable block randomization program.
  All data will be confidentially recorded on a Case Report Form, as will drug reactions and side effects.

Eligibility: Inclusion criteria:
  -  Diagnosed with histologically proven colorectal adenocarcinoma.
  -  Anemic at point of diagnosis of colorectal adenocarcinoma. (Haemoglobin values of <12 g/dL for males and <11 g/dL for females)
  -  Medically fit for surgery.
  -  Date of planned surgery is >14 days from date of planned initiation of intervention (intravenous ferric carboxymaltose /oral ferrous sulphate).
  -  Able and willing to comply with all study requirements.
  -  Willing to allow his/her General Practitioner and consultant, if appropriate, to be notified of participation in the study.
  Exclusion criteria:
  -  Female participants who are pregnant, lactating or planning a pregnancy during the course of the study.
  -  Previous gastric, small bowel or colorectal surgery (where ≥50% of stomach or terminal ileum has been resected)
  -  Current chemotherapeutic treatment.
  -  Known previous anaemia not attributable to colorectal carcinoma (i.e. anaemia in patients with well established inflammatory disorders or chronic renal disease).
  -  Known haematological disease.
  -  Features necessitating urgent surgery (e.g. obstructive symptoms).
  -  Previous allergy to intravenous iron or related iron products.
  -  Significant symptomatic anemia necessitating urgent transfusion (e.g. cardiovascular compromise)
  -  Patients who are unable to consent.
  -  Significant renal or hepatic impairment.
  -  -Donation of blood during the study.
  -  Participants who have participated in another research study involving an investigational product in the past 12 weeks
  -  Prisoners and minors (<18 years)
  -  Any other significant disease or disorder which, in the opinion of the Investigator, may either put the participants at risk because of participation in the study, or may influence the result of the study, or the participant's ability to participate in the study.
