Profile Name PIK3CA wild-type
Gene Variant Detail

PIK3CA wild-type (no effect)

Relevant Treatment Approaches


  • 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
  • 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.

Molecular Profile Indication/Tumor Type Response Type Relevant Treatment Approaches Therapy Name Approval Status Evidence Type Efficacy Evidence References
PIK3CA wild-type breast cancer predicted - sensitive A-1210477 + WEHI-539 Preclinical - Cell culture Actionable In a preclinical study, combination of WEHI-539 and A-1210477 resulted in enhanced apoptosis in PIK3CA wild-type breast cancer cell lines in culture (PMID: 27974663). 27974663
PIK3CA wild-type triple-receptor negative breast cancer no benefit Palbociclib + Pictilisib Preclinical Actionable In a preclinical study, the combination of Ibrance (palbociclib) and Pictilisib (GDC-0941) did not improve growth inhibition compared to single drug treatment in PIK3CA wild-type, triple-receptor negative breast cancer cell lines in culture (PMID: 27020857). 27020857
PIK3CA wild-type Her2-receptor negative breast cancer no benefit Alpelisib Phase I Actionable In a Phase I trial, Alpelisib (BYL719) treatment resulted in no clinical benefit in 4 patients with ER-positive, ERBB2 (HER2)-negative breast cancer harboring PIK3CA mutations (PMID: 29401002; NCT01219699). 29401002
PIK3CA wild-type Advanced Solid Tumor sensitive PX-866 Phase I Actionable In a Phase I study, PX-866 demonstrated efficacy and was well tolerated in patients with advanced solid tumor with both PIK3CA wild-type and mutant status (PMID: 22693357). 22693357
PIK3CA wild-type Her2-receptor positive breast cancer sensitive Lapatinib + Paclitaxel + Trastuzumab Phase II Actionable In a Phase II trial, the combination of Taxol (paclitaxel) plus Herceptin (trastuzumab) and Tykerb (lapatinib) resulted in a higher pathologic complete remission rate in ERBB2 (HER2)-receptor positive breast cancer patients with PIK3CA wild-type compared to those harboring a PIK3CA mutation (PMID: 26245675). 26245675
PIK3CA wild-type breast cancer no benefit Dactolisib + WEHI-539 Preclinical - Cell culture Actionable In a preclinical study, inhibition of Pi3k signaling by BEZ235 did not sensitize PIK3CA wild-type breast cancer cell lines to WEHI-539 in culture (PMID: 27974663). 27974663
