Therapy Name Alpelisib
Synonyms
Therapy Description

Piqray (Alpelisib) is a selective PIK3CA inhibitor that blocks activation of the PI3K signaling pathway and inhibits tumor growth (PMID: 23726034). Piqray (Alpelisib) is FDA approved in combination with fulvestrant for use in postmenopausal women, and men, with advanced or metastatic hormone receptor (HR)-positive, ERBB2 (HER2)-negative, PIK3CA-mutant breast cancer (FDA.gov).

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.
