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.

NRAS G13X Advanced Solid Tumor no benefit MEK inhibitor (Pan) MEK1 Inhibitor MEK2 Inhibitor Binimetinib Phase II Actionable In a Phase II trial (MATCH), Mektovi (binimetinib) treatment resulted in an objective response rate of 2.1% (1/47) that was deemed nonpromising in patients with advanced solid tumors harboring NRAS mutations at codon 12 (n=17), 13 (n=8), or 61 (n=22), with a 6-month progression-free survival (PFS) of 29.2%, a median PFS of 3.5 months, and a median overall survival of 10.5 months (PMID: 33637626; NCT02465060). 33637626
NRAS G13X melanoma predicted - sensitive MEK inhibitor (Pan) Tunlametinib Case Reports/Case Series Actionable In a Phase II trial, Tunlametinib (HL-085) treatment resulted in a confirmed objective response rate (ORR) of 35.8% (34/95, all partial responses), a median progression-free survival of 4.2 months, disease control rate of 72.6% (69/95), median duration of response of 6.1 months, and median overall survival of 13.7 months in Chinese patients with advanced melanoma harboring NRAS mutations, with an ORR of 13.3% in patients with an NRAS G13 mutation (n=5) (PMID: 38479118; NCT05217303). 38479118
