Study Of SU011248 Administered On A Continuous Daily Dosing Schedule In Patients With Gastrointestinal Stromal Tumor

CBR is defined as a confirmed complete response (CR), confirmed partial response (PR), or stable disease (SD) for at least 24 weeks on study according to RECIST. Confirmed responses are those that persisted on repeat imaging >= 4 wks after initial response. Participants with no on-study radiographic tumor re-evaluation counted as non-responders.

Best confirmed response (BCR) defined as best response [confirmed CR, confirmed PR, SD, PD(progressive disease), not evaluable (NE)] recorded from start of treatment until disease progression / recurrence. Best response of SD must have met SD criteria at least once after first dose at minimum interval of 6 weeks.

Overall confirmed objective disease response is defined as a confirmed CR, or confirmed PR according to RECIST. Confirmed responses are those that persisted on repeat imaging >= 4 wks after initial response.

Duration of SD is the time from the date of first documentation of stable disease to the date of first documentation of objective tumor progression or death due to any cause that occurred within 28 days after last dose of study medication, whichever occurred first.

PFS was defined as the time from the date of first dose of study medication to the date of first documentation of objective tumor progression or to death due to any cause that occurred on treatment including within 28 days after the last dose of study medication, whichever occurred first.

TTP was defined as the time from the date of first dose of study medication to the date of first documentation of objective tumor progression that occurred on treatment including within 28 days after the last dose of study medication.

DR was defined as the time from the date of first documentation of objective tumor response (CR or PR) that was subsequently confirmed to the date of the first documentation of objective tumor progression or to death due to any cause that occurred within 28 days after the last dose of study medication, whichever occurred first.

Overall survival is defined as time from the date of first dose of study medication to the date of death due to any cause. One year survival rate defined as the probability that a patient is alive 1 year after the date of first study medication.

FACIT-Fatigue Scale: Overall score from 13-question questionnaire (measures fatigue/asthenia for patients with chronic, life-threatening illnesses). For each question, patient rates condition for the past week on a 5-point Likert scale ranging from 0 (not at all) to 4 (very much). Maximum, minimum mean included data available for >=10 subjects.

EQ-VAS score on the self-rated "thermometer," indicating the patient's own assessment of their health status from 0 (worst) to 100 (best) imaginable health state. Change: median score at observation minus median score at baseline. Maximum changes (Increase or Decrease from baseline) included data available for >=10 subjects.

EQ-5D: health status in 5 dimensions (mobility, self-care, pain/discomfort, anxiety/depression, usual activities) with a weighted health Index based on general population values where 0.0 = death and 1.0 = perfect health. Change: median index score at observation minus median index score at baseline (includes data available for >=10 subjects).
