Response Type sensitive

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.

NTRK2 fusion Advanced Solid Tumor sensitive Larotrectinib Clinical Study - Cohort Actionable In a combined analysis of three trials, Vitrakvi (larotrectinib) resulted in improved median overall survival (39.7 vs 10.2 months) and a 78% lower risk of death (HR=0.22, P=0.001) compared to standard of care treatment in patients with advanced solid tumors harboring NTRK fusions (PMID: 36689698; NCT02122913, NCT02637687, and NCT02576431). 36689698
NTRK2 fusion Advanced Solid Tumor sensitive Larotrectinib Phase Ib/II Actionable In a Phase I/II trial, Vitrakvi (larotrectinib) treatment resulted in complete response in 26.7% (4/15), partial response in 66.7% (10/15), and stable disease in 6.7% (1/15) of pediatric patients with advanced solid tumors harboring NTRK fusions, and progressive diseases in all 7 patients without NTRK fusions (PMID: 29606586; NCT02637687). 29606586
NTRK2 fusion Advanced Solid Tumor sensitive Larotrectinib FDA approved Actionable In three trials that supported FDA approval, Vitrakvi (larotrectinib) treatment resulted in an overall response rate of 75% (41/55) in adult and pediatric patients with advanced solid tumors harboring either an NTRK1, NTRK2, or NTRK3 fusion, including 7 patients achieving a complete response and 34 patients achieving a partial response (PMID: 29466156; NCT02122913, NCT02637687, NCT02576431). detail... 29466156
