About this study
Official title: An Open Label, Two Period, Sequential, Single Dose and Multiple Dose Pharmacokinetic Study With 0.6mg Colchicine Tablets in Healthy Volunteers
This open label, single group, sequential dose study will compare the single dose pharmacokinetics of colchicine 0.6 mg given orally to colchicine pharmacokinetics after 10 days of a standard prophylactic dose (0.6 mg every 12 hours) in healthy volunteers.
Read the detailed description
This open label, single group, sequential dose study will compare the single dose pharmacokinetics of colchicine 0.6 mg given orally to colchicine pharmacokinetics after 10 days of a standard prophylactic dose (0.6 mg every 12 hours) in healthy volunteers. After a fast of at least 10 hours, fourteen healthy non-smoking, non-obese, non-pregnant volunteers will receive a single oral dose of colchicine 0.6 mg. Fasting will continue for 4 hours after the dose, at which time a standard meal will be served. Blood will be drawn from all participants at times sufficient to adequately define the single dose pharmacokinetics of colchicine and its 3 major metabolites, 2, 3 and 10 demethylcolchicine. Following a 14 day washout period, all participants will begin a 10 day regimen of colchicine 0.6 mg orally every 12 hours. On the morning of day 25, after a fast of at least 10 hours, all participants will receive their final dose of colchicine 0.6 mg. Again blood will be drawn at times sufficient to determine the pharmacokinetics of colchicine and its 3 major metabolites after chronic dosing. The pharmacokinetic parameters for each dosing situation will be derived and compared for relevant differences. Though not a specific goal of this study, all participants will be monitored for adverse events by observation and query during periods of confinement on days 1, 15 and 25, as well as by complete blood count (CBC) with differential and clinical chemistry, sitting and standing blood pressures, and heart rate and 12-lead electrocardiogram (EKG) before and after dosing, on days 1 and 25.

What is being measured
The primary outcome is the main question the study is designed to answer.
Maximum Serum Concentration (Cmax)
maximum serum concentration measured after a single oral dose in fasted healthy adults and after a single oral dose in fasted healthy adults at steady state for comparison of the two conditions
Measured: Pharmacokinetic samples collected pre-dose and at 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 24, 36, 48, 72, and 96 hours after dosing
Area Under the Concentration Versus Time Curve From Time Zero to the Time of the Last Measured Level.
Area under the concentration-time curve from time zero to the time of the last quantifiable concentration (t), calculated using the linear trapezoidal rule.
Measured: 0.0, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 24 36, 48, 72, and 96 hours after dosing
Area Under the Concentration Versus Time Curve From Zero to Infinity (AUC 0-inf)
The area under the plasma concentration versus time curve from time 0 to infinity. AUC(0-∞) was calculated as the sum of AUC(0-t) plus the ratio of the last measurable plasma concentration to the elimination rate constant.
Measured: 0.0, 0.5, 1,1.5, 2, 3, 4, 6, 8, 10, 12, 24, 36, 48, 72, and 96 hours after dosing

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing colchicine tablets in people with Pharmacokinetics, run by Mutual Pharmaceutical Company, Inc. 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 3 inclusion and 11 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 20 Nov 2009. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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 20 Nov 2009). 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 Serum Concentration (Cmax) (time frame: Pharmacokinetic samples collected pre-dose and at 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 24, 36, 48, 72, and 96 hours after dosing). The study lists 3 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 20 Nov 2009; AzTrials last refreshed its copy on 7 Nov 2026.
