Profile Name CHEK1 inact mut
Gene Variant Detail

CHEK1 inact mut (loss of function)

Relevant Treatment Approaches Olaparib

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.

CHEK1 inact mut prostate cancer sensitive Olaparib Olaparib FDA approved - On Companion Diagnostic Actionable In a Phase III trial (PROfound) that supported FDA approval, Lynparza (olaparib) treatment significantly improved progression-free survival (PFS, 5.8 vs 3.5 mo, HR=0.49, p<0.001) compared to control in patients with metastatic castration-resistant prostate cancer harboring deleterious or suspected deleterious mutations in homologous recombination repair genes who progressed on hormone therapy, including patients harboring CHEK1 mutations (PMID: 32343890; NCT02987543). detail... detail... 32343890
CHEK1 inact mut prostate cancer sensitive Olaparib Olaparib Case Reports/Case Series Actionable In a Phase II (TOPARP-B) trial, Lynparza (olaparib) treatment resulted in a composite overall response rate of 20.0% (4/20) and a RECIST objective response rate of 0% (0/17) in patients with castration-resistant prostate cancer harboring deleterious mutations in DNA damage response genes, including ARID1A, ATRX, CHEK1/2, FANCA, FANCF, FANCG, FANCI, FANCM, MSH2, NBN, RAD50, and WRN (n=1, 1, 1, 5, 5, 2, 1, 1, 2, 1, 1, 1, 7, respectively) (PMID: 31806540; NCT01682772). 31806540
CHEK1 inact mut prostate cancer sensitive Olaparib Olaparib Guideline Actionable Lynparza (olaparib) is included in guidelines as second-line therapy post androgen receptor-directed therapy for patients with metastatic castration-resistant prostate cancer harboring pathogenic mutations in CHEK1 (NCCN.org). detail...
