Filtering

  • Case insensitive filtering will display rows if any text in any cell matches the filter term
  • Use simple literal full or partial string matches
  • Separate multiple filter terms with a space. Any order may be used (i. e. 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 on a longer phrase with spaces (i.e. "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.

PIK3CA mutant breast cancer no benefit Temsirolimus Phase II Actionable In a Phase II trial (TAPUR), Torisel (temsirolimus) treatment demonstrated limited efficacy in patients with breast cancer harboring PIK3CA mutations, resulting in an objective response rate of 9% (1/12, 1 partial response) and a disease control rate of 9%, which let to the closing of the cohort due to futility (p=0.83) (J Clin Oncol 41, 2023 (suppl 16; abstr 3117); NCT02693535). detail...
