Profile Name CDK12 inact mut
Gene Variant Detail

CDK12 inact mut (loss of function)

Relevant Treatment Approaches PARP Inhibitor (Pan)

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.

CDK12 inact mut prostate cancer sensitive PARP Inhibitor (Pan) 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 CDK12 mutations (5.09 vs 2.20 mo) (PMID: 32343890; NCT02987543). detail... 32343890 detail...

CDK12 inact mut prostate cancer sensitive PARP Inhibitor (Pan) Olaparib Phase II Actionable In a Phase II (TOPARP-B) trial, Lynparza (olaparib) treatment resulted in a composite overall response rate of 25.0% (5/20) and a RECIST objective response rate of 0% (0/18) in patients with castration-resistant prostate cancer harboring deleterious CDK12 mutations (PMID: 31806540; NCT01682772). 31806540
CDK12 inact mut prostate cancer no benefit PARP Inhibitor (Pan) Rucaparib Phase II Actionable In a Phase II trial (TRITON2), activity of Rubraca (rucaparib) was limited in the cohort of patients with metastatic castrate-resistant prostate cancer harboring a CDK12 mutation presumed to be inactivating, with no confirmed radiographic responses in 10 evaluable patients and a PSA response in 1 patient with biallelic CDK12 alterations in the overall population of 15 patients, and a clinical benefit rate of 20% (3/15) at 6 months and 7.1% (1/14) at 12 months (PMID: 32086346; NCT02952534). 32086346
