Relevant Treatment Approaches

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.

ERBB2 amp PIK3CA wild-type uterine corpus serous adenocarcinoma sensitive Neratinib + Taselisib Preclinical - Cell culture Actionable In a preclinical study, the combination of Taselisib (GDC-0032) and Nerlynx (neratinib) delayed cell cycle activity in a uterine serous carcinoma cell line harboring PIK3CA wild-type and ERBB2 (HER2) amplification in culture (PMID: 26333383). 26333383
ERBB2 amp PIK3CA wild-type Her2-receptor positive breast cancer predicted - sensitive Poziotinib Phase II Actionable In a Phase II trial, the presence of high ERBB2 (HER2) copy number and wild-type PIK3CA correlated with improved progression-free survival (HR=0.45, p=0.024) in patients with metastatic Erbb2 (Her2)-positive (amplification or overexpression) breast cancer treated with Poziotinib (HM781-36B) (PMID: 30720867, NCT02418689). 30720867
ERBB2 amp PIK3CA wild-type uterine corpus serous adenocarcinoma sensitive Taselisib Preclinical - Cell line xenograft Actionable In a preclinical study, Taselisib (GDC-0032) did not result in delay of cell cycle activity during treatment of a uterine serous carcinoma cell line harboring PIK3CA wild-type and ERBB2 (HER2) amplification in culture, however, did result in tumor growth inhibition in xenograft models (PMID: 26333383). 26333383
ERBB2 amp PIK3CA wild-type uterine corpus serous adenocarcinoma sensitive Neratinib Preclinical - Cell line xenograft Actionable In a preclinical study, Nerlynx (neratinib) delayed cell cycle activity during treatment of a uterine serous carcinoma cell line harboring PIK3CA wild-type and ERBB2 (HER2) amplification in culture, and inhibited tumor growth in xenograft models (PMID: 26333383). 26333383
