Brief Summary

TThis study evaluates the safety and effectiveness of pre-operative artesunate, given orally once a day for 14 days prior to surgery, in patients with Stage II/III colorectal cancer. Artesunate is an established antimalarial drug with an excellent safety profile. It is well tolerated, affordable, and widely available. Several laboratory studies and one small pilot clinical study in patients with colorectal cancer have shown that artesunate can reduce the proliferation and growth of cancer cells. One hundred patients diagnosed with Stage II/III operable colorectal cancer will be randomly allocated to receive oral artesunate 200 mg daily or a matching placebo for 14 days prior to surgery. Patients will then be followed closely for 5 years to determine whether pre-operative artesunate reduces the risk of cancer recurrence after surgery.

Outcome Measures

Primary Outcomes (1)

  • Recurrence-Free Survival (RFS) at 2 Years Post-Randomisation Assessed by Radiological and Clinical Evaluation

    RFS is defined as the time from randomisation to the first documented recurrence of colorectal cancer (local or distant) or death from any cause, whichever occurs first. Recurrence will be assessed using standard CT scans of the chest, abdomen, and pelvis, clinical examination and measuring carcinoembryonic antigen (CEA). Confirmation of recurrence may include histological evidence where clinically indicated. Unit of Measure: Months

    2 years following study randomisation.

Secondary Outcomes (27)

  • Recurrence-Free Survival at 5 Years Post-Randomisation Assessed by Radiological and Clinical Evaluation

    5 years from study randomisation

  • Overall Survival (OS) at 2 and 5 Years Post-Randomisation

    2 years and 5 years following study randomisation.

  • Colon Cancer-Specific Mortality at 2 and 5 Years Post-Randomisation

    2 years and 5 years following study randomisation.

Model Details: This is a Phase II randomised, placebo-controlled, double-blind trial of neoadjuvant oral artesunate 200 mg once daily for 14 days in patients with histologically confirmed colorectal cancer (CRC) Stage II/III awaiting surgical treatment with curative intent. The study null hypothesis is that there is no difference in survival outcomes between patients with Stage II/III colorectal cancer who receive neoadjuvant artesunate 200 mg once daily for 14 days prior to surgery and those receiving a matching placebo tablet. A randomised, placebo-controlled, double-blind design has been chosen to minimise potential researcher bias. A placebo arm is included as there is currently no standard neoadjuvant treatment in Stage II/III colon cancer.
