- Ages 18 years and older
- 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. For the purposes of this protocol, "clinically significant" is defined as any history or indication of illness or disease, such as those listed above.
- Body Mass Index (BMI) < 31 kg/m2 (weight/height2).
- Female patients of childbearing potential must have negative pregnancy test within 14 days before initiation of study drug dosing. Postmenopausal women must be amenorrheic for at least 12 months to be considered of non-childbearing potential. Female patients 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.
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 has received any other investigational agents within 28 days of first day of study drug dosing.
- Female subjects who are pregnant or breast-feeding.

About this study
Official title: Effect of Calcium Supplements on Imatinib Mesylate (Gleevec®) Pharmacokinetics in Healthy Volunteers (CSTI571BUS 280) (UPCI 08-072)
This research study is being conducted through the University of Pittsburgh Cancer Institute (UPCI). It will evaluate the concentrations of Gleevec®, an oral drug used to treat some types of cancer, in the blood of healthy volunteers when taken with and without Tums Ultra®, a calcium product often used in the treatment of upset stomach and as a calcium supplement.
Read the detailed description
This is an open-label, single-institution, randomized cross-over, fixed-schedule investigation of the effects of calcium carbonate on the pharmacokinetics (PK) of Gleevec® in healthy volunteers. Healthy volunteers will be recruited to participate in this study such that twelve subjects (6 men / 6 women) will complete the study at UPCI. Subjects will be compensated for participation.
Half of the subjects will receive Gleevec® alone on Day 1 and Gleevec® and calcium carbonate on Day 15, and the other half will receive Gleevec® and calcium carbonate on Day 1 and Gleevec® alone on Day 15, determined by randomization of subjects receiving either the combination or Gleevec® alone during the first visit. Doses will be 400 mg Gleevec® and 4000 mg calcium carbonate (4 x Tums Ultra 1000® chewable tablets, equivalent to 4000 mg calcium carbonate or 1600 mg calcium.
Multiple PK blood samples will be taken from Days 1-4 and Days 15-18. Gleevec® PK will be assessed after oral administration of 400 mg Gleevec® alone, and after oral administration of 400 mg Gleevec® with concomitant administration of 4000 mg calcium carbonate. Two 10-hour outpatient dosing visits and six brief outpatient visits are required to accommodate all study procedures.

What is being measured
The primary outcome is the main question the study is designed to answer.
To define the effect of administration of a calcium salt (calcium carbonate) on the PK (in particular the area under the imatinib plasma concentration versus time curve) of imatinib (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, 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 calcium carbonate in people with Healthy, run by Jan Beumer 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 4 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 18 Dec 2013. 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 administration of a calcium salt (calcium carbonate) on the PK (in particular the area under the imatinib plasma concentration versus time curve) of imatinib (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, 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 18 Dec 2013.
