What You Need to Know Before You Apply

What is the purpose of this trial?

This trial studies how well linaclotide works in patients with early-stage colorectal cancer. Linaclotide helps the intestines release water and salt by binding to cell receptors. Researchers want to see if it affects cancer-related markers. Linaclotide is an FDA-approved drug primarily used for treating chronic idiopathic constipation and irritable bowel syndrome with constipation (IBS-C).

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but if you are on chronic anti-coagulants or non-NSAID anti-platelet agents, you may need to stop them if they can't be safely discontinued before study procedures.

How does the drug Linaclotide differ from other treatments for colorectal cancer?

Linaclotide is unique for colorectal cancer treatment because it contains linalool, a compound known for its ability to induce cancer cell death (apoptosis) by generating hydroxyl radicals specifically in cancer cells, which is different from traditional chemotherapy drugs like irinotecan that target rapidly dividing cells more broadly.12345

Are You a Good Fit for This Trial?

This trial is for individuals with stages 0-3 colorectal cancer or those who've had colorectal adenomas. Participants must be able to swallow capsules, sign consent forms, maintain pill diaries, and use effective contraception if of childbearing potential. Exclusions include certain digestive diseases, recent linaclotide use, other cancers treated within the last 6 months (except some skin cancers), current participation in other trials or severe health issues.

Inclusion Criteria

You can easily swallow capsules without any problems.
Participants must have no chronic, clinically severe health issues which, in the opinion of their physician or the research team, could preclude trial activities including the one week drug exposure phase
Ability to maintain pill diaries

What Are the Treatments Tested in This Trial?

Interventions

  • Linaclotide
Trial Overview The study is testing how well linaclotide works for patients with early-stage colorectal cancer by comparing it to a placebo. Linaclotide is a small protein that encourages intestinal cells to release water and salt. The trial will see if this treatment can benefit patients awaiting surgery.
How Is the Trial Designed?
2Treatment groups
Experimental Treatment
Placebo Group
Group I: Arm I (linaclotide)Experimental Treatment1 Intervention

Group II: Arm II (placebo)Placebo Group1 Intervention
Patients receive placebo PO QD on days 1-7 and undergo standard of care colonoscopy or surgery on day 7.

Published Research Related to This Trial

The combination of fluorouracil (5-FU)/leucovorin and irinotecan (CPT-11) has significantly improved response rates and survival times for patients with metastatic colorectal cancer, making it a recommended first-line treatment.
Ongoing randomized phase III trials in Europe are investigating the efficacy of this combination as adjuvant chemotherapy for patients with stage II or III colorectal cancer, aiming to enhance cure rates in those with resected, locally advanced, nonmetastatic disease.
