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.

Molecular Profile Indication/Tumor Type Response Type Therapy Name Approval Status Evidence Type Efficacy Evidence References
PIK3CA E542K PIK3CA amp lung squamous cell carcinoma sensitive Alpelisib Preclinical - Pdx Actionable In a preclinical study, Alpelisib (BYL719) treatment resulted in response in a lung squamous cell carcinoma patient-derived xenograft (PDX) model harboring PIK3CA E542K and PIK3CA amplification (PMID: 30093452). 30093452
PIK3CA E542K PIK3CA amp lung squamous cell carcinoma sensitive Buparlisib Preclinical - Pdx Actionable In a preclinical study, Buparlisib (BKM120) treatment resulted in inhibition of AKT and S6 phosphorylation and durable response in a lung squamous cell carcinoma patient-derived xenograft (PDX) model harboring PIK3CA E542K and PIK3CA amplification (PMID: 30093452). 30093452
CDKN2A loss PIK3CA E542K PIK3CA amp lung squamous cell carcinoma sensitive Buparlisib + Palbociclib Preclinical - Pdx Actionable In a preclinical study, treatment with the combination of Buparlisib (BYL719) and Ibrance (palbociclib) resulted in increased tumor growth inhibition compared to either agent alone in a patient-derived xenograft (PDX) model of lung squamous cell carcinoma harboring PIK3CA E542K and PIK3CA amplification, with p16 (CDKN2A) loss (PMID: 30093452). 30093452
ERBB2 pos PIK3CA E542K Her2-receptor positive breast cancer predicted - sensitive Neratinib Phase III Actionable In a Phase III trial (ExteNET), Nerlynx (neratinib) treatment resulted in improved 5-year invasive disease-free survival (92.4% vs 84.5%, HR=0.41, p=0.028) and clinical benefit (HR=0.40, p=0.041) compared to placebo in patients with ERBB2 (HER2)-positive early breast cancer who completed trastuzumab-based adjuvant therapy, and harbored PIK3CA amplification (n=61) or mutations (n=210), including H1047R (n=110), E542K (n=18), and E545K/D (n=82) (PMID: 30867034; NCT00878709). 30867034
HRAS mut PIK3CA E542K malignant glioma sensitive Buparlisib + Selumetinib Preclinical - Cell culture Actionable In a preclinical study, the combination therapy of Buparlisib (BKM120) and Koselugo (selumetinib) led to a synergistic effect, resulting in growth inhibition of astrocytoma cells with an HRAS mutation expressing PIK3CA E542K in culture, but at a higher drug concentration compared to cells without mutant HRAS (PMID: 29975751). 29975751
PIK3CA E542K PIK3CA F744L head and neck squamous cell carcinoma sensitive Sulindac Preclinical - Pdx Actionable In a preclinical study, Clinoril (sulindac) treatment reduced tumor growth rate in patient-derived xenograft (PDX) models of head and neck squamous cell carcinoma harboring PIK3CA mutations, including a model harboring PIK3CA E542K and PIK3CA F744L (PMID: 30683736). 30683736
