Trial Outcomes & Findings for Sunitinib Malate After Stereotactic Radiosurgery in Treating Patients With Newly Diagnosed Brain Metastases (NCT NCT00910039)

NCT ID: NCT00910039

Last Updated: 2014-09-29

Results Overview

The number of subjects surviving at least six months from SRS without progressive disease anywhere in the brain (local or regional failure), assessed by the McDonald's standard criteria.Progressive neurologic abnormalities not explained by causes unrelated to tumor progression (e.g. anticonvulsant or corticosteroid toxicity, electrolyte abnormalities, hyperglycemia, etc.) or a greater than 25% increase in the size of the tumor by MRI/CT scan.

Participant milestones

Participant milestones
Measure
Sunitinib Malate
Oral sunitinib malate (37.5mg) once daily on days 1-28. Courses repeat every 42 days in the absence of disease progression or unacceptable toxicity. Patients undergo neuropsychological battery testing at baseline and periodically during study to assess cognitive function (memory, verbal fluency, visual-motor speed, executive function, and motor dexterity), activities of daily living, and quality of life.

SECONDARY outcome

Timeframe: 12 months

Population: Due to the small number of patients accrued there was not enough data for analysis of this outcome.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: at 2 months after treatment

Population: Due to the small number of patients accrued there was not enough data for analysis of this outcome.

The number of patients that had statistically significant change (p's \> 0.05) in their neurocognitive assessment (improvement or decline) from baseline. Neurocognitive function was assessed in several domains, including memory, verbal fluency, visual-motor speed, executive function and motor dexterity.The difference between the pre-treatment baseline and follow-up assessment scores were determined by the reliable change (RC) index. RC Index: 1=deterioration, 2=no change, 3=improved
