Description:
This phase II trial studies the how well linaclotide works in treating patients with stages
0-3 colorectal cancer. Linaclotide is a very small protein that binds to receptors on
intestinal cells and makes them secrete water and salt.

Purpose
This phase II trial studies the how well linaclotide works in treating patients with stages
0-3 colorectal cancer. Linaclotide is a very small protein that binds to receptors on
intestinal cells and makes them secrete water and salt.
Detailed Description
PRIMARY OBJECTIVES:
I. To determine whether, compared to placebo, linaclotide administered as a single oral daily
dose x 7 days, induces a pharmacodynamics (PD) effect on cGMP levels, based on biopsy samples
of adenomas or resected colorectal adenocarcinomas.
SECONDARY OBJECTIVES:
I. To compare Ki-67, guanylin levels and GUCY2C expression in adenomas and cancers versus
normal tissue.
II. To confirm the safety and tolerability of linaclotide in sporadic adenoma and cancer
patients.
Trial Arms
Name | Type | Description | Interventions |
---|
Arm I (linaclotide) | Experimental | Patients receive linaclotide PO daily on days 1-7 and undergo standard of care colonoscopy or surgery on day 8. | |
Arm II (placebo) | Placebo Comparator | Patients receive placebo PO QD on days 1-7 and undergo standard of care colonoscopy or surgery on day 8. | |
Eligibility Criteria
Inclusion Criteria:
- History of 1 or more sporadic colorectal adenoma on previous endoscopy (adenoma
cohort) or stage 0-3 biopsy proven colorectal cancer (CRC) (colorectal cancer cohort)
who are scheduled for a surgical procedure
- Ability to understand and willingness to sign a written informed consent document and
follow study procedures
- Ability to swallow capsules without difficulty
- Ability to maintain pill diaries
- Willingness to employ adequate contraception for men and women of childbearing
potential for the duration of the study. Acceptable methods include double barrier
methods, intrauterine device (IUD), postmenopausal status, and/or documentation of
surgical sterilization
- 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
Exclusion Criteria:
- History of gastroparesis
- History of celiac disease
- Inflammatory bowel disease (Crohn's disease, ulcerative colitis)
- Microscopic colitis, including collagenous colitis
- Currently taking or have previously taken Linaclotide
- Any malignancy within 3 years of baseline except colorectal cancer. Participants with
a history of basal cell or squamous cell skin cancer may be enrolled at the discretion
of the investigator
- Participants may not be receiving any other investigational agents, or be active
participants in any clinical trials. If participants previously participated in a
clinical trial, a 30 day washout period for the investigational drug is needed before
the participant can be considered for this study
- History of allergic reactions attributed to compounds of similar chemical or biologic
composition to linaclotide
- Uncontrolled current illness including, but not limited to, ongoing or active
infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac
arrhythmia, or psychiatric illness/social situations that would limit compliance with
study requirements
- Pregnant or lactating women
- History of bleeding/coagulation problems. Concurrent use of nonsteroidal
anti-inflammatory drugs (NSAIDs) including aspirin is acceptable
- Any medical condition judged by the investigator to constitute a risk to safe
participation
- At risk for obstructing or near-obstructing mechanical gastrointestinal obstruction
- Chronic use of anti-coagulants or non-NSAID anti-platelet agents will serve as an
exclusion only when such medications cannot be safely discontinued before study
related endoscopy or surgery
Maximum Eligible Age: | 70 Years |
Minimum Eligible Age: | 18 Years |
Eligible Gender: | Female |
Healthy Volunteers: | No |
Primary Outcome Measures
Measure: | Pharmacodynamics effect on cGMP levels |
Time Frame: | Up to 2 years |
Safety Issue: | |
Description: | Will compare cGMP levels in adenomas between study arms using a two-sample t-test (alpha=.05; two-sided) or Wilcoxon rank sum test. |
Secondary Outcome Measures
Measure: | Incidence of adverse events (AEs) |
Time Frame: | From day 7 to day 14 |
Safety Issue: | |
Description: | All participants will be evaluated for toxicity from the time of their first dose of linaclotide or placebo. Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 will be used to summarize adverse events associated with linaclotide. |
Measure: | Ki-67 expression |
Time Frame: | Up to 2 years |
Safety Issue: | |
Description: | Wilcoxon rank sum test will be used to compare Ki-67 expression in adenomas across arms. |
Measure: | GUCY2C expression |
Time Frame: | Up to 2 years |
Safety Issue: | |
Description: | Wilcoxon rank sum and Fisher's exact tests will be used to compare GUCY2C expression between study arms. |
Measure: | Guanylin levels |
Time Frame: | Up to 2 years |
Safety Issue: | |
Description: | Wilcoxon rank sum and Fisher's exact tests will be used to compare guanylin levels between study arms. |
