Therapy Description

BLU-667 selectively inhibits activated Ret, which may result in decreased tumor growth (Mol Cancer Ther 2018;17(1 Suppl):Abstract nr B151).

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.

Drug Name Trade Name Synonyms Drug Classes Drug Description
Pralsetinib Gavreto BLU667|BLU-667 RET Inhibitor 40 Gavreto (pralsetinib) is a small molecule inhibitor that selectively targets activated Ret, which may result in antitumor activity including inhibition of tumor growth and tumor regression (PMID: 29657135). Gavreto (pralsetinib) is FDA approved for use in patients with metastatic MET fusion-positive non-small cell lung cancer, in adult and pediatric patients 12 years of age and older with advanced or metastatic RET-mutant medullary thyroid cancer, and in adult and pediatric patients 12 years of age and older with RET fusion-positive thyroid cancer who are radioactive iodine-refractory (FDA.gov).
