| Synonyms | |
| Therapy Description | |
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.
| Drug Name | Trade Name | Synonyms | Drug Classes | Drug Description |
|---|---|---|---|---|
| Cetuximab | Erbitux | IMC-C225 | EGFR Antibody 56 | Erbitux (cetuximab) is a monoclonal antibody directed against EGFR, which inhibits signal transduction and cell proliferation (PMID: 28695301). Erbitux (cetuximab) is FDA approved for use in head and neck squamous cell carcinoma and KRAS wild-type, EGFR positive colorectal cancer (FDA.gov). |
| Encorafenib | Braftovi | LGX818 | BRAF Inhibitor 25 | Braftovi (encorafenib) is an inhibitor of Raf kinase with selective activity against BRAF V600E, resulting in growth inhibition (PMID: 24864047). Braftovi (encorafenib) is FDA approved for use in combination with Mektovi (binimetinib) in patients with unresectable or metastatic melanoma with a BRAF V600E or V600K mutation, and in patients with metastatic non-small cell lung cancer harboring BRAF V600E, and in combination with Erbitux (cetuximab) in patients with metastatic colorectal cancer with BRAF V600E (FDA.gov). |
