Profile Name ATM negative
Gene Variant Detail

ATM negative (loss of function)

Relevant Treatment Approaches Olaparib


  • 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")


  • 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.

Molecular Profile Indication/Tumor Type Response Type Relevant Treatment Approaches Therapy Name Approval Status Evidence Type Efficacy Evidence References
ATM negative stomach cancer no benefit Olaparib + Paclitaxel Phase III Actionable In a Phase III trial (GOLD), addition of Lynparza (olaparib) to Taxol (paclitaxel) did not significantly improve overall survival (12.0 vs 10.0 months, HR=0.73, p=0.25) compared to Taxol (paclitaxel) alone in Asian patients with ATM-negative gastric cancer (PMID: 29103871; NCT01924533). 29103871
ATM negative Advanced Solid Tumor predicted - sensitive BAY1895344 Phase I Actionable In a Phase I trial, BAY1895344 treatment was tolerated and resulted in an objective response rate of 36.4% (4/11, all partial responses) and a disease control rate of 63.6% (7/11) in patients with advanced solid tumors harboring ATM inactivating mutations and/or ATM protein expression loss (PMID: 32988960; NCT03188965). 32988960
ATM negative collecting duct carcinoma predicted - sensitive BAY1895344 Case Reports/Case Series Actionable In a Phase I trial, BAY1895344 treatment resulted in a partial response with a 69% decrease in tumor size in a patient with renal collecting duct carcinoma harboring ATM protein loss, treatment was ongoing at 385 days (PMID: 32988960; NCT03188965). 32988960
ATM negative stomach cancer predicted - sensitive Ceralasertib + Durvalumab Phase II Actionable In a Phase II trial, Ceralasertib (AZD6738) and Imfinzi (durvalumab) combination therapy resulted in an overall response rate of 22.6% (7/31, all partial responses), disease control rate of 58.1%, and median progression-free survival (mPFS) of 3.0 mo in advanced gastric cancer patients, with improved mPFS (5.60 vs 1.65 mo; HR 0.13, p<0.001) in patients with ATM protein loss and/or homologous repair deficiency (HRD) compared to those with intact ATM expression or HR proficiency (PMID: 35790315; NCT03780608). 35790315
