Clinical Trial 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.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	To determine if the use of intravenous ferric carboxymaltose can reduce the need for allogeneic blood transfusion compare to oral ferrous sulphate in patients with colorectal adenocarcinoma related anaemia	To investigate if the number of units transfused per participant, the number of participants whom receive a blood transfusion and the total number of units of blood transfused differs between the two study arms. This period monitored will begin at enrolment into the study, and cease at review in outpatient clinic 6 - 12 weeks post operatively.	0 - 6 to 12 weeks	Yes
Secondary	To determine differences in hemoglobin and hematinic markers between the groups.	Hematinic markers include ferritin, iron, transferrin, transferrin saturation, erythropoietin.	Enrollment to 6-12 weeks postoperatively	No
Secondary	To determine differences in hepcidin levels in relation to blood profile changes in participants in the intravenous group.	To review the use of hepcidin as a biomarker to predict response to therapy.	Enrollment to 6-12 weeks postoperatively.	No
Secondary	To determine differences in colonic mucosal expression of iron transport proteins, C-myc and NKD1 between the groups	Iron transport proteins include DMT TFR1, Ferroportin, Ferritin. As acquired from examination of pathology tissue specimen excised.	At point of operation only	No
Secondary	To determine differences in postoperative outcomes between the groups.	Post-operative outcomes include morbidity, mortality, length of stay.	Enrollment to 6-12 weeks postoperatively	No
Secondary	To determine differences in anemia symptomatology response between groups.	Quality of Life questionnaires will be used (SF-36[short form 36] and EQ-5D)	Enrollment to 6-12 weeks postoperatively	No
