Patient Information:

PATIENT COUNSELING INFORMATION

1. Dosing and Administration

Patients should be informed to take Gleevec exactly as prescribed, not to change

their dose or to stop taking Gleevec unless they are told to do so by their doctor.

If patients miss a dose they should be advised to take their dose as soon as possible

unless it is almost time for their next dose in which case the missed dose should

not be taken. A double dose should not be taken to make up for any missed dose.

Patients should be advised to take Gleevec with a meal and a large glass of water.

2. Pregnancy and Breast-Feeding

Patients should be advised to inform their doctor if they are or think they may be

3. Adverse Reactions

Patients should be advised to tell their doctor if they experience side effects during

Gleevec therapy including fever, shortness of breath, blood in their stools,

jaundice, sudden weight gain, symptoms of cardiac failure, or if they have a

history of cardiac disease or risk factors for cardiac failure.

4. Drug Interactions

Patients should be advised not to take any other medications, includin

over-the-counter medications such as acetaminophen or herbal products

without talking to their doctor or pharmacist first. Examples of other medications

that should not be taken with Gleevec are warfarin, erythromycin, and phenytoin.

5.Patients should also be advised to tell their doctor if they are taking or plan to

take iron supplements.

6.Patients should also avoid grapefruit juice and other foods known to inhibit

CYP3A4 while taking Gleevec.

Pharmacology/ Pharmacokinetics:

CLINICAL PHARMACOLOGY

1. Mechanism of Action

Imatinib mesylate is a protein-tyrosine kinase inhibitor that inhibits the bcr-abl tyrosine

kinase, the constitutive abnormal tyrosine kinase created by the Philadelphia

chromosome abnormality in CML. Imatinib inhibits proliferation and induces

apoptosis in bcr-abl positive cell lines as well as fresh leukemic cells from

Philadelphia chromosome positive chronic myeloid leukemia.

Imatinib inhibits colony formation in assays using ex vivo peripheral blood

and bone marrow samples from CML patients.

2. Pharmacokinetics

The pharmacokinetics of Gleevec have been evaluated in studies in healthy

subjects and in population pharmacokinetic studies in over 900 patients.

The pharmacokinetics of Gleevec are similar in CML and GIST patients.

Imatinib is well absorbed after oral administration with Cmax achieved within

2-4 hours post-dose. Mean absolute bioavailability is 98%.

Following oral administration in healthy volunteers, the elimination half-lives

of imatinib and its major active metabolite, the N-demethyl derivative (CGP74588),

are approximately 18 and 40 hours, respectively

Pregnancy and lactation:

USE IN SPECIFIC POPULATIONS

1. Pregnancy

Pregnancy Category D

2. Nursing Mothers

It is not known whether imatinib mesylate or its metabolites are excreted in human milk.

Because many drugs are excreted in human milk and because of the potential

for serious adverse reactions in nursing infants from Gleevec, a decision should

be made whether to discontinue nursing or to discontinue the drug, taking into

account the importance of the drug to the mother.

3. Pediatric Use

Gleevec safety and efficacy have been demonstrated in children with newly

diagnosed Ph+ chronic phase CML and in children with Ph+ chronic phase

CML with recurrence after stem cell transplantation or resistance to

interferon-alpha therapy. There are no data in children under 2 years of age.

Follow-up in children with newly diagnosed Ph+ chronic phase CML is limited.

As in adult patients, imatinib was rapidly absorbed after oral administration

in pediatric patients, with a Cmax of 2-4 hours.

4. Geriatric Use

In the CML clinical studies, approximately 40% of patients were older than 60 years

and 10% were older than 70 years. In the study of patients with newly diagnosed

CML, 22% of patients were 60 years of age or older.

No difference was observed in the safety profile in patients older than 65 years

as compared to younger patients, with the exception of a higher frequency

of edema

The efficacy of Gleevec was similar in older and younger patients.

No obvious differences in the safety or efficacy profile were noted in patients

older than 65 years as compared to younger patients, but the small number of

patients does not allow a formal analysis.
