Trial Information

Chart Review Study of Chronic Myelogenous Leukemia (CML) Patients Treated With Imatinib Outside of a Clinical Trial

PATIENT POPULATION:

All patients with CML in any phase of the disease (chronic, accelerated or blast phase) that
has received treatment with imatinib not on an MDACC clinical trial regardless of prior
treatment history, and has had at least one clinic visit at MDACC will be eligible.

STUDY PLAN:

The following information will be collected:

- Demographic information including age, gender, ethnicity, education, and work history.

- All laboratory values obtained at MDACC or other institutions, including CBC, blood
chemistries, electrolytes, bone marrow aspirations and biopsies, cytogenetic analyses,
FISH, and PCR.

- Treatment history including starting and stopping dates, doses, treatment
interruptions, dose changes and reasons for dose modifications.

- Information about toxicity including type, grade, dates of onset and resolution,
interventions to manage toxicity, and sequelae.

- Information regarding pregnancy or conception during imatinib therapy for both male and
female patients, including dates of pregnancy, outcome of pregnancy, interventions
during pregnancy, management of CML during pregnancy, complications during pregnancy,
status of the product, condition of the born child, and information on lactation.

This information will be reviewed from the documents received as part of the routine
communication with the local oncologist or from the studies obtained at MDACC.

There will be no treatment changes or recommendations as a result of this study. This study
will be strictly limited to review of charts. Patients will continue their treatment as
recommended by their local oncologist and treating physician at MDACC.

These results will be compared to similar patients treated with imatinib in the context of
clinical trials both from published literature and from studies conducted at MDACC. The
response rates, duration of response, toxicity, dose intensity, and rate of transformation
will be compared.

Investigators will review data from July 1, 1998 to October 31, 2008.

SAMPLE SIZE:

Approximately 850 charts will be reviewed.
