  • 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"


  • 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

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
