Authority prescription form
A completed authority prescription form must be
included with this document.
The medical indication section of the authority
prescription form does not need to be completed when
submitted with this supporting information form.


Applications for continuing treatment
Patients who achieve a response to treatment at an
imatinib dose of 400 mg per day should be continued
at this dose and assessed for response at regular
intervals.
A response to treatment is defined as a decrease from
baseline in the sum of the products of the perpendicular
diameters of all measurable lesions of 50% or greater.
(Response definition based on the Southwest Oncology
Group standard criteria, see Demetri et al. N Engl J Med
2002; 347: 472-80.)
