Description of intervention(s) / exposure
This is a multi centre, open label, side-by-side comparator study to assess the safety, feasibility and validity of lymphatic staging using the standard of care lymphadenectomy and histopathology process compared with using investigational products in combination being FerroTrace and ICG for mapping sentinel lymph nodes (SLNs), as an adjunct to the standard of care lymphadenectomy in subjects with colorectal cancer. The study will also investigate the feasibility of assessing lymph nodes for metastasis using FerroTrace enhanced MRI in rectal cancer subjects and in colon cancer subjects at the discretion of the Investigator, with MRI performed when the Investigator believes bowel motion artefacts will not affect the MRI or does not expose the patients to unacceptable COVID risk. A maximum of 40 subjects will be enrolled. Eligible subjects will receive a single dose of 0.4-0.5ml (27mg Fe) of FerroTrace and a single dose of 0.4-0.5ml of ICG(1.25mg) administered via four equal volume endoscopic peri-tumoural submucosal injections each of 1/4 of the dose, administered either separately for subjects part of the MRI protocol, or together during surgery for those not including MRI. Subjects with the optional MRI will receive a pre-injection MRI of the pelvis followed by the endoscopic FerroTrace™ injections, and a post-injection MRI of the pelvis 2 – 30 h after injection. During surgery, subjects will receive the ICG injections. Subjects not including the MRI will receive the FerroTrace™/ICG injections during surgery. For all subjects, the standard of care surgery and lymphadenectomy will be performed. At the surgeon’s discretion, a near infrared (NIR) surgical camera may be used to identify and remove extra-regional LNs they assess to contain FerroTrace and ICG. An ex vivo survey of the excised specimen using a magnetometer probe and near infrared camera will be performed to locate specimen SLNs. Histopathology will be as per standard of care for all LNs in the lymphadenectomy specimen, plus more detailed ultra-staging of SLNs using serial slicing and immunochemistry. The fidelity of the intervention is ensured by only specialists with endoscopy accreditation being used for the injection of the investigational product, and a video being recorded of the injection for monitoring purposes.

Comparator / control treatment
The standard of care lymphadenectomy and histopathology process consists of the surgical removal of a specimen (Complete Mesocolic Excision for colon cancer and Total Mesorectal Excision in rectal cancer), followed by the sampling of lymph nodes from the specimen by histopathology and an examination of each of the sampled nodes using Hematoxylin & Eosin as per protocol recommendations of the Royal College of Pathologists of Australasia (RCPA) for structured reporting of colorectal cancer and staged as per the 8th edition of the AJCC Cancer Staging Manual (2017)

Safety/efficacy
Statistical methods / analysis
A maximum of 40 subjects will be included in this study.

The planned number of subjects is considered appropriate to make an initial determination on the safety and efficacy of FerroTrace and ICG for sentinel lymph node mapping in colorectal cancer.

The Bayesian method will be applied for interim toxicity monitoring. Toxicity is defined as any CTCAE v5.0 Grade III or greater AE attributable to FerroTrace injection. We assume as a priori, p(TOX) ~ ß (0.3, 0.7). The trial will be stopped early due to toxicity if Pr(p(TOX)> 0.30 | data) >0.70, i.e., we will stop the trial for new subject enrolment if we determine that there is >70% chance that the toxicity rate is >30%. The toxicity monitoring rule will be applied starting from the 5th subject, and then in cohort sizes of 5

The study will be stopped if 3 or more of the first 5 subjects, 5 or more of the first 10 subjects, 6 or more of the first 15 subjects, 8 or more of the first 20 subjects, 9 or more of the first 25 subjects, 11 or more of the first 30 subjects, or 13 or more of the first 35 subjects have experienced FerroTrace related CTCAE Grade III or worse adverse events.

Summary
Brief summary
The purpose of this study is to evaluate the safety of a new magnetic tracer (FerroTrace) and an infrared dye (Indocyanine Green - ICG) to be used together in colorectal cancer surgery to find the lymph nodes the cancer is most likely to have spread to (the sentinel lymph nodes).

This study will also evaluate the feasibility and accuracy of the new magnetic tracer (FerroTrace) and infrared dye (ICG) for finding the sentinel lymph nodes. If the sentinel nodes are clear of cancer, there is a very high probability the cancer has not spread.

Finally, the study will also investigate whether the new tracer enables better detection of cancer cells in lymph nodes on Magnetic Resonance Imaging (MRI) before surgery.

Who is it for?
You may be eligible to join this study if you are aged between 18 and 75 years, have a confirmed diagnosis of primary colorectal cancer and are scheduled for surgery to remove the primary tumour.

Study details
All participants will undergo their surgery to remove the primary tumour as originally scheduled, with the addition of receiving the new magnetic tracer (Ferrotrace) and the infrared dye (ICG) during the surgery.

Participants will then be monitored for 14 days after the surgery for complications.

It is hoped that this research project will demonstrate the new method is safe and feasible, and can enable larger follow on trials to determine if the new method improves staging accuracy and can improve patient outcomes.
