Abstract Text Bevacizumab ((BEV) has become a mainstay of treating recurrent glioblastoma, but eventual tumor resistance is expected. Targeting multiple growth-associated signaling pathways may result in more effective treatment than targeting VEGF alone. Patients with recurrent glioblastoma were stratified by prior BEV exposure and treated with sunitinib 37.5 mg daily in this phase II study. Response evaluations were performed at baseline and at the end of every 4 week cycle. Six-month progression-free survival (PFS6) was the primary endpoint for both arms of the study. Secondary endpoints included health related quality of life measures and FDG-PET correlatives with patient outcomes. Sixty-three patients were accrued to this study; thirty-two were BEV-naïve, 31 were BEV-resistant. PFS6 was 10.4 % [95 % CI 3.2-33.8] in the BEV-naïve cohort and 0 % in the BEV-resistant cohort. Median overall survival was 9.4 months [95 % CI 6.15-21.90] in the BEV-naïve cohort and 4.37 months [95 % CI 3.02-6.21] in the BEV-resistant cohort. 3/29 patients (10 %) of the BEV-naïve, and 0/27 BEV-resistant patients achieved radiographic response. Thrombocytopenia, leukopenia, and neutropenia were the most common drug-associated adverse events and occurred with higher frequency than expected. Sunitinib treatment in BEV-naïve patients did not appear to affect outcomes with subsequent BEV therapy. Continuous daily sunitinib did not prolong progression-free survival in BEV-naïve nor BEV-resistant patients with recurrent glioblastoma.

Filtering

  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page, filtering has no impact on query parameters
  • Use quotes to match a longer phrase which contains spaces "mtor c1483f"

Sorting

  • Generally, the default sort order for tables is set to be first column ascending, however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column, be sure to set ascending or descending order for a given column, before moving on to the next column.
