August 11, 2026 updated by: Hamilton Health Sciences Corporation
Phase 2 basket trial including 2 open-label single-arm cohorts: REPAIR CKD cohort and REPAIR Dialysis cohort. Open label colchicine 0.3 mg daily for 8 weeks followed, in patients who tolerated the 0.3 mg dose, by forced titration to 0.6 mg daily for 8 weeks.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The REPAIR CKD cohort will enroll 100 patients with chronic kidney disease not requiring dialysis. The REPAIR Dialysis cohort will enroll 100 patients with chronic kidney disease requiring chronic maintenance dialysis. Each participant will be followed for up to 17 weeks, to determine among adults with severe chronic kidney disease not requiring dialysis and (separately) in those requiring dialysis, the proportion who, over 8 weeks of treatment, discontinue colchicine 1) 0.3 mg daily and 2) 0.6 mg daily.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Dose tolerance
Time Frame: Up to 17 weeks
Proportion of participants who permanently discontinue colchicine at either the 0.3 mg daily dose or 0.6 mg daily dose (to estimate the proportion who would discontinue the study drug at the 0.6 mg daily dose without titration).
Up to 17 weeks
Early discontinuations
Time Frame: Up to 17 weeks
Proportion of participants who permanently discontinue colchicine at the 0.3 mg daily dose.
Up to 17 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Reason for drug discontinuation
Time Frame: Up to 17 weeks
To determine the reasons for temporary and permanent discontinuations of colchicine at the 0.3 mg and 0.6 mg daily doses.

Drug adherence
Time Frame: Up to 17 weeks
To determine degree of adherence to colchicine at the 0.3 mg and 0.6 mg daily doses.

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants.
