Drug-Drug Interaction Study Between Colchicine and Atorvastatin
A Phase 1 study testing Colchicine and Atorvastatin in people with Healthy, run by Mutual Pharmaceutical Company, Inc. at 1 site in United States.
Trial summary
Colchicine is a substrate for cytochrome P450 3A4 (CYP3A4). In-vitro studies have indicated that the ortho-and para-hydroxylated metabolites of atorvastatin may be CYP3A4/5 competitive and mechanism-based inhibitors (MBI). Read more about this study

About this study
Official title: A One-Directional, Open-Label Drug Interaction Study to Investigate the Effects of Multiple-Dose Atorvastatin on the Single-Dose Pharmacokinetics of Colchicine in Healthy Volunteers
Colchicine is a substrate for cytochrome P450 3A4 (CYP3A4). In-vitro studies have indicated that the ortho-and para-hydroxylated metabolites of atorvastatin may be CYP3A4/5 competitive and mechanism-based inhibitors (MBI). This study will evaluate the effect of multiple doses of atorvastatin on the pharmacokinetic profile of a single 0.6 mg dose of colchicine. A secondary objective is to evaluate the safety and tolerability of this regimen in healthy volunteers. All study subjects will be monitored for adverse events throughout the study period.

Colchicine is a substrate for cytochrome P450 3A4 (CYP3A4). In-vitro studies have indicated that the ortho-and para-hydroxylated metabolites of atorvastatin may be CYP3A4 /5 competitive and mechanism-based inhibitors (MBI). This study will evaluate the effect of multiple doses of atorvastatin on the pharmacokinetic profile of a single 0.6 mg dose of colchicine. Twenty-four healthy, non-smoking, non-obese, non-pregnant adult volunteers between the ages of 18 and 45 will be given one oral dose of colchicine (1 x 0.6 mg tablet) on Day 1 after an overnight fast. Blood samples will be drawn from all participants before dosing and for 24 hours post-dose at times sufficient to adequately define the pharmacokinetics of colchicine. After a 14 day washout period, starting on the morning of Day 15 and continuing through Day 27, subjects will return to the clinic for once daily administration of atorvastatin (1 x 40 mg tablet) after an overnight fast. After taking the first dose of atorvastatin on Day 15, subjects will remain in the clinic for 1 hour post-dose administration for observation. On the morning of Day 28 after an overnight fast, all study participants will receive a co-administered single oral dose of colchicine (1 x 0.6 mg tablet) and atorvastatin (1 x 40 mg tablet). Blood samples will be drawn from all participants before dosing and for twenty-four hours post-dose at times sufficient to adequately define the pharmacokinetics of colchicine in the presence of atorvastatin at steady state. A further goal of this study is to evaluate the safety and tolerability of this regimen in healthy volunteers. Subjects will be monitored throughout participation in the study for adverse reactions to the study drug and/or procedures. Seated blood pressure and pulse, respiratory rate and temperature will be measured at screening, baseline and upon study discharge. Blood pressure and pulse will also be measured pre-dose and at 1 and 2 hours post-dose on Days 1 and 28 to coincide with peak plasma concentrations of colchicine and atorvastatin. All adverse events whether elicited by query, spontaneously reported, or observed by clinic staff will be evaluated by the investigator and reported in the subject's case report form.

| Study group | Role | What they receive |
|---|---|---|
| Colchicine Alone | Active comparator | baseline colchicine pharmacokinetics Receives: Drug: Colchicine |
| Colchicine with Atorvastatin | Experimental | Colchicine pharmacokinetics in the presence of atorvastatin at steady state. Receives: Drug: Atorvastatin; Drug: Colchicine |
What is being measured
The primary outcome is the main question the study is designed to answer.
Maximum Plasma Concentration (Cmax) of Colchicine
The maximum or peak concentration that colchicine reaches in the plasma.
Measured: serial pharmacokinetic blood samples drawn prior to dosing on Days 1 and 28 and then 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 12 and 24 hours after dose administration.
Area Under the Concentration Versus Time Curve From Time 0 to Time t [AUC(0-t)]
The area under the plasma concentration versus time curve from time 0 to the time of the last measurable concentration (t), as calculated by the linear trapezoidal rule for colchicine.
Measured: Serial pharmacokinetic blood samples drawn prior to dosing on Days 1 and 28 and then 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 12 and 24 hours after dose administration.
Area Under the Concentration Versus Time Curve From Time 0 Extrapolated to Infinity [AUC(0-∞)]
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 for colchicine.
Measured: Serial pharmacokinetic blood samples drawn prior to dosing on Days 1 and 28 and then 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 12 and 24 hours after dose administration.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Colchicine and Atorvastatin in people with Healthy, 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 4 inclusion and 8 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 30 Mar 2010. 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 16 Mar 2010). 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) of Colchicine (time frame: serial pharmacokinetic blood samples drawn prior to dosing on Days 1 and 28 and then 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 12 and 24 hours after dose administration.). 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?
On the ClinicalTrials.gov record for NCT00960323, which also lists 1 linked publication.
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 30 Mar 2010.
