Comparison Bioavailability Study of Quinine Sulfate in Chocolate Pudding

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.

About this study

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).

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Healthy nonsmoking adults with hemoglobin at least 12 g/dl. Males at least 52 kg, females at least 45kg with body mass index in the normal range, females must be chemically or surgically sterile or postmenopausal (amenorrhea at least 2years)

Exclusion criteria

  • Pregnant or lactating
  • Test positive at screening for human immunodeficiency virus (HIV), hepatitis B surface antigen (HbsAg), or hepatitis C virus (HCV) Recent (1-year) history or evidence of alcoholism or drug abuse History or presence of significant cardiovascular, pulmonary, hepatic, renal, hematological, gastrointestinal, endocrine, immunologic, dermatologic, neurological, or psychiatric disease, myasthenia gravis, optic neuritis or Glucose-6-phosphate dehydrogenase (G6PD) deficiency
  • Prolonged corrected QT interval(QTc) on Electrocardiogram(EKG) at screening -males >430 msec, females >450 msec.

PR interval on EKG >200 msec at screening or prior to dose in either dosing period

Treatment and study plan

quinine sulfate

Drug

2 x 324 mg capsules (648 mg)

Other names: Qualaquin

Primary outcomes

  1. 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 highest concentration of drug in plasma after a dose. Measured to evaluate the bioequivalence of the two dosing methods

  2. Area Under the Concentration Time Curve From Zero to t. (AUC 0-t)

    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 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.

  3. The Area Under the Plasma Concentration Versus Time Curve From Time Zero to Infinity. (AUC Inf)

    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

    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
