About this study
The purpose of this study is to evaluate and compare the relative bioavailability of Quinine Sulfate 324 mg capsules, manufactured by the Mutual Pharmaceutical Company, to Quinine Sulphate 300 mg tablets, manufactured by the Government Pharmaceutical Organization, Bangkok Metropolis, Thailand, after single oral dose administration under fasting conditions. An additional purpose of this study is to evaluate the effect of food on the Mutual Pharmaceutical Company product.

The purpose of this study is to evaluate and compare the relative bioavailability of Quinine Sulfate 324 mg capsules, manufactured by the Mutual Pharmaceutical Company, to Quinine Sulphate 300 mg tablets, manufactured by the Government Pharmaceutical Organization, Bangkok Metropolis, Thailand, after single oral dose administration under fasting conditions. An additional purpose of this study is to evaluate the effect of food on the Mutual Pharmaceutical Company product.
Twenty-seven healthy, non-smoking, non-obese, male and female volunteers at least 18 years of age will be randomly assigned in crossover fashion to receive each of three dosing regimens in sequence with a 7 day washout period between dosing periods. In each of the three dosing periods, after a fast of at least 10 hours, subjects will receive one dose of one of the three test products (treatment A - quinine sulfate capsules 324 mg, treatment B - quinine sulphate tablets 300 mg, treatment C - quinine sulfate capsules 324 mg administered thirty minutes after the initiation of a standardized, high-fat breakfast). Subjects will fast for 4 hours after dosing. Blood samples will be drawn from all participants before dosing and for 48 hours post-dose at times sufficient to adequately define the pharmacokinetics of quinine sulfate under fed and fasting conditions and quinine sulphate under fasting conditions. Sitting blood pressure and heart rate will be obtained prior to dosing and at 1, 2, 4 and 12 hours post-dose and upon completion of the study. An electrocardiogram will be recorded at check-in and at 2, 4, 6, 12, and 24 hours post-dose. Subjects will be monitored throughout their participation in the study for adverse reactions.

What is being measured
The primary outcome is the main question the study is designed to answer.
Maximum Plasma Concentration (Cmax)
The maximum or peak concentration that the drug reaches in the plasma.
Measured: serial pharmacokinetic blood samples drawn within one hour prior to dosing (hour 0) and at 0.5, 1, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 10, 12, 16, 24, 36 and 48 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.
Measured: serial pharmacokinetic blood samples drawn within one hour prior to dosing (hour 0) and at 0.5, 1, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 10, 12, 16, 24, 36 and 48 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.
Measured: serial pharmacokinetic blood samples drawn within one hour prior to dosing (hour 0) and at 0.5, 1, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 10, 12, 16, 24, 36 and 48 hours after dose administration.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Quinine Sulfate Capsules 324 mg and Quinine Sulphate Tablets 300 mg 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 14 inclusion and 18 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 Jan 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 30 Dec 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 Plasma Concentration (Cmax) (time frame: serial pharmacokinetic blood samples drawn within one hour prior to dosing (hour 0) and at 0.5, 1, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 10, 12, 16, 24, 36 and 48 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?
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 Jan 2010.
