Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 65 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Who may be able to join

  • 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.

Who cannot join

  • 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.

About this study

Official title: Effect of a Proton Pump Inhibitor (Omeprazole, Prilosec®) on Imatinib Mesylate (Gleevec®) Pharmacokinetics in Healthy Volunteers (CSTI571BUS258)

This is a research study that will investigate the effects of proton pump inhibitors (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 proton pump inhibitors (PPI). Each volunteer will receive a 400 mg pill of Gleevec® on two occasions. On one occasion they will take the dose of Gleevec® alone (without PPI). On another occasion, they will take the Gleevec® after taking 40 mg of PPI daily by mouth for six days. 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 PPI.

Read the detailed description

This is an open-label, single-institution, randomized cross-over, fixed schedule study of the effects of proton pump inhibitors (PPI) on Imatinib Mesylate (Gleevec®) pharmacokinetics. Healthy volunteers will be recruited to participate in this study such that twelve subjects (6 men / 6 women) will complete the study. Gleevec® pharmacokinetics will be assessed after oral administration of Gleevec® and after oral administration of Gleevec® with concomitant administration of PPI (Prilosec® Delayed-Release Capsules). Gleevec® will be administered at a dose of 400 mg, and the PPI (Prilosec®) at a dose level of 40 mg daily for 6 consecutive days. Half of the subjects will receive Prilosec® starting 5 days before Day 1 through Day 1 along with Gleevec® on Day 1, and Gleevec® alone on Day 15. The other half will receive Prilosec® on Days 10-15, along with Gleevec® on Day 15, and Gleevec® alone on Day 1. On days that both drugs are administered, the Prilosec® will be administered 15 minutes before the Gleevec® dose.

  • OmeprazoleDrug

    Also called Prilosec®, Proton Pump Inhibitor

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To define the effect of omeprazole administration on the pharmacokinetics (in particular the area under the Gleevec® plasma concentration versus time curve) of Gleevec® in healthy volunteers.

    Measured: PK blood samples are drawn from each subject at time 0 (before each dose of Gleevec®), and at 0.5, 1, 2, 3, 4, 5, 6, 8, 12, 24, 48, and 72 hrs after adminstration of Gleevec®.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Imatinib Mesylate and Omeprazole in people with Healthy, run by University of Pittsburgh 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 5 inclusion and 6 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 22 Jun 2016. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

To define the effect of omeprazole administration on the pharmacokinetics (in particular the area under the Gleevec® plasma concentration versus time curve) of Gleevec® in healthy volunteers. (time frame: PK blood samples are drawn from each subject at time 0 (before each dose of Gleevec®), and at 0.5, 1, 2, 3, 4, 5, 6, 8, 12, 24, 48, and 72 hrs after adminstration of Gleevec®.). 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 22 Jun 2016.
