| Therapy Name | Talazoparib |
| Synonyms | |
| Therapy Description |
Talzenna (talazoparib) is an inhibitor of PARP1 and PARP2, which prevents the DNA repair of single strand DNA breaks, thus causing the accumulation of DNA strand breaks, genomic instability and apoptosis, and leads to lethality in homologous recombination repair deficient cells (PMID: 28242752). Talzenna (talazoparib) is FDA approved for use in patients with ERBB2 (HER2)-negative breast cancer harboring deleterious or suspected deleterious germline BRCA mutations (FDA.gov). |
Filtering
- Case insensitive filtering will display rows if any text in any cell matches the filter term
- Use simple literal full or partial string matches
- Separate multiple filter terms with a space. Any order may be used (i. e. 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 on a longer phrase with spaces (i.e. "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.
