Trial Outcomes & Findings for Pazopanib in Treating Patients With Recurrent Glioblastoma (NCT NCT00459381)

Subjects accrued between June 2007 to January 2008 at 4 NABTC Cancer Centers using their outpatient facilities. Survival follow-up extended to June 2009

Pazopanib in Treating Patients With Recurrent Glioblastoma

Calculated from study registration till 6month time point. Progression defined by Macdonald criteria Progression imaging features: 25% of more increase in enhancing lesions; any new lesions clinical features: clinical deterioration

Use NCI Common toxicity Criteria Adverse Event Version 3.0 to grade toxicities. Any patient who received at least one dose of pazopanib was evaluable for toxicity. Calculated the number of participants who had an event that was related to pazopanib that caused the patient to stop treatment due to this event.

NCI Common Toxicity Criteria (CTCAE) version 3.0. All patients that received at least one dose of pazopanib were evaluable. All events recorded that were related to drug were calculated per patient.

The Macdonald criteria, roughly similarly to other systems, divides response into 4 types of response based on imaging (MRI) and clinical features 1: complete response; 2: partial response; 3:stable disease; 4:progression Complete response imaging features: disappearance of all enhancing disease (measurable and non-measurable) sustained for at least 4 weeks; no new lesions clinical features; no corticosteroids; clinically stable or improved Partial response imaging features: 50% or more decrease of all measurable enhancing lesions sustained for at least 4 weeks: no new lesions clinical features: stable or reduced corticosteroids; clinically stable or improved Stable disease imaging features: does not qualify for complete response, partial response or progression clinical features: clinically stable Progression imaging features: 25% of more increase in enhancing lesions; any new lesions clinical features: clinical deterioration

Using the Macdonald criteria, the best MRI image response while the patient was on active treatment. 1: complete response; 2: partial response; 3:stable disease; 4:progression Complete response imaging features: disappearance of all enhancing disease (measurable and non-measurable) sustained for at least 4 weeks; no new lesions clinical features; no corticosteroids; clinically stable or improved Partial response imaging features: 50% or more decrease of all measurable enhancing lesions sustained for at least 4 weeks: no new lesions clinical features: stable or reduced corticosteroids; clinically stable or improved Stable disease imaging features: does not qualify for complete response, partial response or progression clinical features: clinically stable Progression imaging features: 25% of more increase in enhancing lesions; any new lesions clinical features: clinical deterioration

calculated from study registration until date of death or patient censored at the last date known alive

PFS for patients who died on treatment or within 30 days of the end of treatment w/out progression date, was date of death. All other pts without documented progression were censored at the date of last follow-up prior to start new treatment. All 35 patients were included in an intent to treat analysis for PFS and OS. 3 pts censored for PFS, all less than 2 wks after study registration.
