Trial comparing treatments for Rectal Cancer

Official title Neoadjuvant Chemotherapy, Excision And Observation vs Chemoradiotherapy For Rectal Cancer

ClinicalTrials.gov ID: NCT06205485

What this study is testing

What is Leucovorin?

Leucovorin is an investigational drug being studied as part of treatment for rectal cancer. Leucovorin is designed to enhance the activity of certain chemotherapy agents by stabilizing their binding to thymidylate synthase.

Also referred to as folinic acid.

Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
The study wants to see whether giving only chemotherapy before limited surgery gives the same chance of tumor response as giving chemotherapy with radiation together. It also asks if patients have a better quality of life when radiation is not used.
Who it's for
Adults with rectal cancer who are candidates for limited surgery.
What's involved
Participants will receive either chemotherapy alone or chemotherapy plus radiation before surgery, then have the surgery and be followed up. They will have regular visits and tests to monitor the cancer and health.
Time commitment
The study lasts about 6–12 months, with several clinic visits for treatment, surgery, and follow‑up assessments.
  • Phase 3: a large, late-stage study
  • Time commitment: about 5 years

Who can take part

Ages 18 and older

You may be able to join if

  • Histologically confirmed invasive, well-moderately differentiated rectal adenocarcinoma, mismatch repair proficient.
  • MRI stage cT1 not eligible for transanal surgery or cT2-T3ab\ . \ T3a: \<1mm depth invasion, T3b: 1-5mm depth of invasion.
  • cN0 stage based on pelvic MRI - including absence of radiographic evidence of mesorectal nodal metastasis, tumour deposits or extramural venous...
  • M0 stage based on no evidence of metastatic disease by CT imaging of chest, abdomen and pelvis.
  • Mid to low-lying tumour eligible for transanal excision in the opinion of the treating surgeon.

You likely can't join if

  • Pathologic high-risk factors on diagnostic biopsy: high histologic grade (poorly differentiated), mucinous or signet ring histology.
  • Patients with visible pelvic sidewall nodes on MRI.
  • Patients with unequivocal determination of nodal disease that, in the opinion of the investigator, would prohibit protocol therapy administration.
  • Previous pelvic radiation for any reason, including brachytherapy alone.
  • Patients who have had primary lesion excised prior to enrollment. If a patient has had partial excision prior to enrollment, there must be gross...
  • Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or how...
