About this study
Official title: A Comparison of the Bioavailability of Quinine Sulfate Capsules Following a 648 mg Dose When Mixed in Chocolate Pudding Relative to That With Intact Capsules in Healthy Adults Under Fasting Conditions
This is an open label randomized single dose two-way crossover study to compare the bioavailability of a single oral dose of quinine sulfate 648 mg(2 x 324 mg) when mixed with 120 ml of chocolate pudding relative to the same dose given as two intact capsules.
Read the detailed description
Prior studies have shown that intact quinine sulfate capsules can be taken without regard for food. This is an open label randomized single dose two-way crossover study to compare the bioavailability of a single oral dose of quinine sulfate 648mg(2 x 324 mg capsules) when opened and mixed with 120 ml of chocolate pudding relative to the same dose given as two intact capsules. Eighteen healthy adult subjects will be enrolled. Following a fast of at least 10 hours subjects will be randomized to receive either 648 mg of quinine sulfate as the intact capsules or opened mixed in 120ml of chocolate pudding. Following a washout period of at least 7 days all subjects will be given the alternate dose under similar conditions. Following each dose, blood samples will be collected at times sufficient to determine the difference in bioavailability (if any) between the two methods of drug administration. In addition patients will be monitored for any adverse events including Electrocardiogram (EKG) changes (at baseline and 4 hours after each dose).

What is being measured
The primary outcome is the main question the study is designed to answer.
Maximum Observed Plasma Concentration (Cmax)
The highest concentration of drug in plasma after a dose. Measured to evaluate the bioequivalence of the two dosing methods
Measured: After dosing at time points 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 10, 12, 16, 24, 36, and 48 hours
Area Under the Concentration Time Curve From Zero to t. (AUC 0-t)
The area under the plasma concentration versus time curve from zero to the last measurable plasma concentration as calculated by the linear trapezoidal method. Calculated to determine whether the 2 methods of administration are bioequivalent.
Measured: After dosing at time points 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 10, 12, 16, 24, 36, and 48 hours
The Area Under the Plasma Concentration Versus Time Curve From Time Zero to Infinity. (AUC Inf)
AUC inf is calculated as the sum of the AUC 0-t plus the ratio of the last measurable plasma concentration to the elimination rate constant.It is calculated to evaluate the bioequivalence of the two dosing methods
Measured: After dosing at time points 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 10, 12, 16, 24, 36, and 48 hours

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing quinine sulfate in people with Healthy, run by Mutual Pharmaceutical Company, Inc. at 1 site in Canada.
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 1 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 31 Aug 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 Canada. 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 8 Jul 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 Observed Plasma Concentration (Cmax) (time frame: After dosing at time points 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 10, 12, 16, 24, 36, and 48 hours). 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 31 Aug 2012.
