About this study
Official title: Single-Dose, Open-Label Study of the Pharmacokinetics, Safety, and Tolerability of Colcrys (Colchicine, USP) Tablets 0.6 mg Administered to Healthy Subjects and Subjects With Mild, Moderate, Severe Renal Impairment, and End-Stage Renal Disease
The primary objective of this study is to compare the pharmacokinetic profiles of colchicine and its primary metabolites in plasma and urine following a single 0.6 mg oral dose of colchicine in healthy adults with normal renal function, in patients with mild, moderate or severe renal impairment, and in patients with end-stage renal disease on hemodialysis. An additional objective of this study is to study the clearance of colchicine and its metabolites by hemodialysis. Secondary objectives include evaluation of the safety and tolerability of colchicine in the study population.
Read the detailed description
40 male and female subjects will be enrolled in the study and stratified into one of five groups based on their renal status as determined from creatinine clearance (CrCL) estimated using the serum creatinine (sCR) and the Cockcroft-Gault and Modified Diet in Renal Disease (MDRD) equations as follows: Treatment group 1 - healthy adults with normal renal function (CrCL/eGFR> 90 mL/min); Treatment groups 2, 3 and 4 - patients with mild (CrCL/eGFR 60-89 mL/min), moderate (CrCL/eGFR 30 to 59 mL/min), and severe (CrCL/eGFR 15 to 29 mL/min) renal impairment, respectively; and Treatment group 5 - subjects with end-stage renal disease requiring hemodialysis. On study day 1, participants in Treatment Groups 1 to 4 will be administered one colchicine 0.6 mg tablet at 8 a.m. under standard fasting conditions. Blood samples will be collected from all participants before dosing and both blood and urine samples will be collected for 120 hours post-dose on a confined basis at times sufficient to adequately define the pharmacokinetics of colchicine and its primary metabolites. There will be two study periods for treatment group 5; Period 1 off dialysis and Period 2 on dialysis with a 14 day washout period between the two study periods. On study day 1, participants in treatment group 5 will be administered one colchicine 0.6 mg tablet under standard fasting conditions immediately following dialysis. Blood samples will be collected from all participants before dosing and for up to 70 hours post-dose at times sufficient to adequately determine the pharmacokinetics of colchicine and its primary metabolites. All adverse events will be evaluated by the investigator and reported in the participant's case report form.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The primary objective of this study is to compare the pharmacokinetic profiles of colchicine and its primary metabolites in plasma and urine following a single 0.6 mg oral dose of colchicine in healthy adults with normal renal function, in patients with mild, moderate or severe renal impairment, and in patients with end-stage renal disease on hemodialysis. An additional objective of this study is to study the clearance of colchicine and its metabolites by hemodialysis. Secondary objectives include evaluation of the safety and tolerability of colchicine in the study population.
Detailed description
40 male and female subjects will be enrolled in the study and stratified into one of five groups based on their renal status as determined from creatinine clearance (CrCL) estimated using the serum creatinine (sCR) and the Cockcroft-Gault and Modified Diet in Renal Disease (MDRD) equations as follows: Treatment group 1 - healthy adults with normal renal function (CrCL/eGFR> 90 mL/min); Treatment groups 2, 3 and 4 - patients with mild (CrCL/eGFR 60-89 mL/min), moderate (CrCL/eGFR 30 to 59 mL/min), and severe (CrCL/eGFR 15 to 29 mL/min) renal impairment, respectively; and Treatment group 5 - subjects with end-stage renal disease requiring hemodialysis. On study day 1, participants in Treatment Groups 1 to 4 will be administered one colchicine 0.6 mg tablet at 8 a.m. under standard fasting conditions. Blood samples will be collected from all participants before dosing and both blood and urine samples will be collected for 120 hours post-dose on a confined basis at times sufficient to adequately define the pharmacokinetics of colchicine and its primary metabolites. There will be two study periods for treatment group 5; Period 1 off dialysis and Period 2 on dialysis with a 14 day washout period between the two study periods. On study day 1, participants in treatment group 5 will be administered one colchicine 0.6 mg tablet under standard fasting conditions immediately following dialysis. Blood samples will be collected from all participants before dosing and for up to 70 hours post-dose at times sufficient to adequately determine the pharmacokinetics of colchicine and its primary metabolites. All adverse events will be evaluated by the investigator and reported in the participant's case report form.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Colchicine in people with Pharmacokinetics, run by Takeda at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 12 Oct 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 12 Oct 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Maximum Plasma Concentration (Cmax) (time frame: Day 1 and Day 15 (for ESRD patients only) pre-dose and at 0.5, 1, 1.5 , 2, 3, 4, 5, 6, 8, 12, 24, 36, 48, 72, 96, 120 hours post dose). The study lists 15 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Oct 2012.
