Condition(s) targeted: Healthy

Intervention: Quinine Sulfate 2 x 324 mg Capsules (Drug); Quinine Sulfate 2 x 324 mg Capsules (Drug)

Phase: Phase 1

Status: Completed

Sponsored by: Mutual Pharmaceutical Company, Inc.

Summary

The purpose of this study is to evaluate and compare the relative bioavailability of Quinine Sulfate capsules following a single, oral dose in healthy volunteers under fasting and fed conditions.

Clinical Details

Official title: A Relative Bioavailability Study of Quinine Sulfate Capsules 324mg Under Fasting and Fed Conditions

Study design: Allocation: Randomized, Endpoint Classification: Bio-availability Study, Intervention Model: Crossover Assignment, Masking: Open Label, Primary Purpose: Basic Science

Primary outcome:

Maximum Plasma Concentration (Cmax) for Quinine Sulfate

Area Under the Concentration Versus Time Curve From Time 0 to Time t [AUC(0-t)] for Quinine Sulfate

Area Under the Concentration Versus Time Curve From Time 0 Extrapolated to Infinity [AUC(0-∞)] for Quinine Sulfate

Detailed description: The purpose of this study is to evaluate and compare the relative bioavailability of Quinine Sulfate capsules following a single, oral dose in healthy volunteers under fasting and fed conditions. Twenty-two healthy, non-smoking, non-obese, male and female volunteers between the ages of 18 and 45 years of age will be randomly assigned in a crossover fashion to receive each of two Quinine Sulfate dosing regimens in sequence with a 7 day washout period between dosing periods. On the morning of Day 1, subjects will receive either a single oral dose of Quinine Sulfate (2 x 324 mg capsules) following an overnight fast of at least 10 hours, or a single oral dose of Quinine Sulfate (2 x 324 mg capsules) 30 minutes after a standardized, high-fat breakfast. After a 7 day washout period, on the morning of Day 8, subjects will receive the alternate regimen. Blood samples will be drawn from all participants before dosing and for 48 hours post-dose to adequately define the pharmacokinetics of Quinine Sulfate. A further goal of this study is to evaluate the safety and tolerability of this regimen in healthy volunteers. Subjects will be monitored throughout the confinement portion of the study for adverse reactions to the study drug and/or procedures. Blood pressure and heart rate will be measured prior to dosing and at 1, 2, 4 and 12 hours after each dose and at study exit. A 12 lead electrocardiogram (EKG) will be recorded at study check-in and at 2, 4, 6, 12 and 24 hours after dose administration. 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.

Eligibility

Minimum age: 18 Years. Maximum age: 45 Years. Gender(s): Both.

Criteria:

Inclusion Criteria:

- Screening Demographics: All volunteers selected for this study will be healthy men

and women 18 to 45 years of age at the time of dosing. Weight range will not exceed ±20% for height and body frame

- Screening Procedures: Each volunteer will complete the screening process within 28

days prior to Period I dosing. Consent documents for both the screening evaluation and human immunodeficiency virus (HIV) antibody determination will be reviewed, discussed, and signed by each potential participant before full implementation of screening procedures

- Screening will include general observations, physical examination, demographics,

medical history, an electrocardiogram, sitting blood pressure and heart rate, respiratory rate and temperature. The physical examination will include, but may not be limited to, an evaluation of the cardiovascular, gastrointestinal, respiratory and central nervous systems

- Screening Procedures:

- Hematology: hematocrit, hemoglobin, white blood cell (WBC) count with differential,

red blood cell (RBC) count, platelet count

- Clinical chemistry: serum creatinine, blood urea nitrogen (BUN), glucose, AST(SGOT -

Serum glutamic-oxaloacetic transaminase), ALT(SGPT - Serum glutamic-pyruvic

transaminase), albumin, total bilirubin, total protein, and alkaline phosphatase

- HIV antibody, hepatitis B surface antigen, hepatitis C antibody screens

- Urinalysis: by dipstick; full microscopic examination if dipstick positive; and

- Urine drug screen: ethyl alcohol, amphetamines, barbiturates, benzodiazepines,

cannabinoids, cocaine metabolites, opiates and phencyclidine

- Serum pregnancy screen (female volunteers only)

- If female and:

- of childbearing potential, is practicing an acceptable method of birth control for

the duration of the study as judged by the investigator(s), such as condom with spermicide, diaphragm with spermicide, intrauterine device (IUD), or abstinence; or

- is postmenopausal for at least 1 year; or

- is surgically sterile (bilateral tubal ligation, bilateral oophorectomy, or

hysterectomy). Exclusion Criteria:

- Volunteers with a recent history of drug or alcohol addiction or abuse

- Volunteers with a presence of a clinically significant disorder involving the

cardiovascular, respiratory, renal, gastrointestinal, immunologic, hematologic, endocrine, or neurologic system(s) or psychiatric disease (as determined by clinical investigators)

- Volunteers whose clinical laboratory test values are outside the accepted reference

range and when confirmed on re-examination are deemed to be clinically significant

- Volunteers demonstrating a reactive screen for hepatitis B surface antigen, hepatitis

C antibody or HIV antibody

- Volunteers demonstrating a positive drug abuse screen when screened

- Female volunteers demonstrating a positive pregnancy screen

- Female volunteers who are currently breastfeeding

- Volunteers with a history of allergic response(s) to quinine or related drugs

- Volunteers with a history of clinically significant allergies including drug

allergies

- Volunteers with a clinically significant illness during the last 4 weeks prior to

Period I dosing (as determined by the clinical investigators)

- Volunteers who report donating greater than 150 mL of blood within 28 days prior to

Period I dosing. All subjects will be advised not to donate blood for four weeks after completing the study

- Volunteers who have donated plasma (e. g. plasmapheresis) within 14 days prior to

Period I dosing. All subjects will be advised not to donate plasma for four weeks after completing the study

- Volunteers who report receiving any investigational drug within 28 days prior to

Period I dosing

- Volunteers who report taking any systemic prescription medication in the 14 days

prior to Period I dosing

- Volunteers who currently use tobacco products

- Volunteers who have taken any drug known to induce or inhibit hepatic drug metabolism

in the 28 days prior to Period I dosing

- Male volunteers with a corrected QT interval (QTc)> 430 milliseconds (msec)on the

screening electrocardiogram (ECG) or with clinically significant findings

- Female volunteers with a QTC> 450 msec on the screening ECG or with clinically

significant findings
