- Female patients of childbearing potential with a negative pregnancy test within 7 days of initiation of study drug dosing. Postmenopausal women must be amenorrheic for at least 12 months to be considered of non-childbearing potential. Male and female patients of reproductive potential who agree to employ an effective barrier method of birth control throughout the study, and for up to 3 months following discontinuation of study drug.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Imatinib mesylate + hydroxyurea (HU)
Imatinib was supplied as 100 mg and 400 mg tablets.
Patients in the combination arm were instructed to take a daily oral imatinib dose of 600 mg (600 mg at lunch time) and a daily oral hydroxyurea (HU) dose of 1000 mg (500 mg twice daily; in the morning and at bed time).
Every 6 weeks after randomization based on assessment of therapeutic response, either patients continued with above mentioned dosing regimen or switched to receive a daily dose of 800 mg imatinib with 1000 mg HU.
Patients were instructed to split the intake, taking 400 mg imatinib with 500 mg HU in the morning, then the same in the evening.

Other Names:
Imatinib was supplied as 100 mg and 400 mg tablets packaged in polyethylene bottles.
Other Names:

Active Comparator: Hydroxyurea alone
1500 mg/day of HU given as 500 mg 3 times daily.
Every 6 weeks after randomization and based on assessment of therapeutic response, the patients were either switched to combination arm or continued in monotherapy arm of hydroxyurea.

Measure Description |
Time Frame |
---|---|---|
Percentage of Participants With Progression Free Survival (PFS) During the Study Duration
Time Frame: 6 months -1 year
|
PFS was defined as the time from the date of randomization to the date of the first documented progression according to the MacDonald criteria, or death due to any cause.
MacDonald criteria are standard criteria in neurooncology.
Tumor assessment was made according to the adapted MacDonald criteria based on the combined evaluation of 1) assessment of the MRI scan for measurable, evaluable, and new lesions (made by the independent external expert too), 2) overall assessment of neurological performance (made by the investigator), 3) concomitant steroid use (as reported by the investigator).

Measure Description |
Time Frame |
---|---|---|
Number of Participants With Death, Other Serious or Clinically Significant Adverse Events (AEs) or Related Discontinuations
Time Frame: 6 months - 1 year
|
National Cancer Institute (NCI)/ National Institute of Health (NIH) provides a grading (severity) scale for each AE term.
Grade 3 refers to severe AE and Grade 4 refers to life-threatening or disabling AE.
According to FDA 21CFR 314.80, a serious adverse event (SAE) is described as any adverse event that leads to death, is life threatening ( NIH criteria Grade 4), causes or prolongs hospitalization, results in a congenital anomaly, or any other important medical event not described above.
