October 5, 2009 updated by: Mutual Pharmaceutical Company, Inc.

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.

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.

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

18 years to 45 years (Adult)

Accepts Healthy Volunteers

Yes

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.
