Effect of Antacids on Gleevec® in Healthy Volunteers

Completed · Phase 1

Conditions studied: Healthy

In brief

This is a research study that will investigate the effects of antacids (often used to treat stomach upset) on Gleevec® (a drug that is FDA-approved to treat some types of cancer) in healthy volunteers. Twelve healthy volunteers (six men and six women) will be recruited to complete the study. This research study will compare Gleevec® in the body when taken with and without antacids. Each volunteer will receive a 400 mg pill of Gleevec® on two occasions. One one occasion they will take the dose of Gleevec® alone. On another occasion, they will take the Gleevec® 15 minutes after taking a 20 mL dose of antacids. Several blood samples will be drawn to measure the concentrations of Gleevec® and its breakdown products in the blood, with and without the influence of antacids.

Who can join

Age: 18 and older, up to 65. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Healthy men or women 18 years of age or older. Healthy subjects are defined as individuals who are free from clinically significant illness or disease (such as coronary arterial disease, chronic heart failure, bleeding disorder, hypertension, chronic renal failure etc.) as determined by their medical history, physical examination, and laboratory studies.
• Body Mass Index (BMI) < 31 kg/m\^2 (weight/height\^2).
• Female subjects of childbearing potential must have negative pregnancy test within 7 days before initiation of study drug dosing. Postmenopausal women must be amenorrheic for at least 12 months to be considered of non-childbearing potential. Male and female subjects of reproductive potential must agree to employ an effective barrier method of birth control throughout the study and for up to 7 days following discontinuation of study drug.
• Written, voluntary informed consent.
• Subjects participating in the protocol entitled "IRB: 0701014: Effect of Antacids (Mg-Al-based) on Imatinib Mesylate (Gleevec®) Pharmacokinetics in Healthy Volunteers (CSTI571BUS257) (UPCI #06-088)" will be eligible for participation in this study provided they meet all other eligibility criteria for this study.

You may not qualify if…

• Abnormal marrow function as defined by leucocyte, neutrophil, or platelet counts outside of normal limits.
• Any evidence of renal dysfunction (proteinuria; serum creatinine > upper limit of normal; or if serum creatinine > upper limit of normal, a calculated creatinine clearance < 60 mL/min/1.73 m2).
• Impaired hepatic function (liver enzymes greater than the upper limit of normal or bilirubin outside the normal range).
• Taking any medications (including over the counter products), herbal products, mineral supplements or vitamins (other than a daily multivitamin preparation), other than contraceptives (for women), within 2 weeks of start of the study. All forms of contraceptive medication are permissible for this study and would not result in a female's exclusion from participation. Patients who take medications on a chronic basis, such as antihypertensive medications or thyroid replacement therapy, etc. are not eligible for the study.
• Subjects that have received any other investigational agents within 28 days of first day of study drug dosing.
• Female subjects who are pregnant or breast-feeding.
