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 act mut estrogen-receptor positive breast cancer predicted - sensitive Palbociclib + Taselisib Phase I Actionable In a Phase Ib trial (PIPA), the combination of Ibrance (palbociclib) with Taselisib (GDC-0032) was well tolerated in estrogen-receptor negative breast cancer patients harboring PIK3CA activating mutations and resulted in an objective response rate of 10% (1/10), a clinical benefit rate of 30% (4/10), and a median progression-free survival of 3.6 months (PMID: 32958578; NCT02389842). 32958578
