HRAS act mut (unknown)

Relevant Treatment Approaches

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.

HRAS act mut transitional cell carcinoma predicted - sensitive Tipifarnib Phase II Actionable In a Phase II trial, Zarnestra (tipifarnib) demonstrated safety and preliminary efficacy in patients with metastatic urothelial carcinoma harboring HRAS mutations (n=14) or STK11:rs2075606, 3 of 4 patients achieved progression-free survival at 6 months harbored HRAS activating mutations, and no response was observed in HRAS wild-type patients (J Clin Oncol 38: 2020 (suppl; abstr 5086); NCT02535650). detail...
HRAS act mut salivary gland carcinoma sensitive Tipifarnib Clinical Study Actionable In a clinical study, Zarnestra (tipifarnib) treatment resulted in an overall response rate of 8% (n=13) with one ongoing partial response with a duration of 14 months and stable disease as the best response in 58% (7/12) of evaluable patients with HRAS-mutant metastatic salivary gland carcinoma, and a median overall survival of 18 months, and a median progression-free survival of 7 months (PMID: 32557577). 32557577
HRAS act mut Advanced Solid Tumor no benefit Selumetinib Clinical Study - Cohort Actionable In a Phase II trial (MATCH), Koselugo (selumetinib) treatment resulted in a 15% (3/20) six-month progression-free survival rate, no objective responses, and did not lead to tumor regression in pediatric patients with advanced solid tumors including high grade glioma (n=8) and rhabdomyosarcoma (n=7) that harbored MAPK pathway alterations including activating HRAS, KRAS, or NRAS mutations, BRAF V600E, or inactivating NF1 mutations (J Clin Oncol 39, no. 15_suppl (May 20, 2021) 10008; NCT03213691, NCT03155620). detail...
