| Therapy Name | GDC-0077 |
| Synonyms | |
| Therapy Description |
GDC-0077 inhibits PIK3CA, with selectivity for mutant PIK3CA over wild-type PIK3CA, potentially resulting in increased apoptosis and decreased growth of PIK3CA-mutant tumors (AACR; Cancer Res 2017;77(13 Suppl):Abstract nr 156). |
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.
