Study Arms:
- Imatinib mesylate+hydroxyurea (Type: EXPERIMENTAL): All patients receive imatinib mesylate and hydroxyurea orally on a daily, continuous basis. Dosing of imatinib mesylate is adjusted for patients who are also receiving p450-inducing anti-epileptic drugs.

Based on this trial design, predict the completion outcome and termination type (if applicable).
