Profile Name PBRM1 inact mut
Gene Variant Detail

PBRM1 inact mut (loss of function)

Relevant Treatment Approaches EZH2 inhibitor

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.

PBRM1 mutant clear cell renal cell carcinoma conflicting Everolimus Phase II Actionable In a Phase II trial (RECORD-3), PBRM1 mutations were associated with longer first-line progression free survival (12.8 vs 5.5 months) in first-line Afinitor (everolimus)-treated clear cell renal cell carcinoma patients compared to first-line Sutent (sunitinib)-treated patients (PMID: 27751729). 27751729
PBRM1 mutant clear cell renal cell carcinoma conflicting Everolimus Clinical Study - Cohort Actionable In a clinical study, PBRM1 truncating mutations were not associated with progression-free survival or overall survival in clear cell renal cell carcinoma patients treated with Afinitor (everolimus) (n=193) (PMID: 31486842). 31486842
PBRM1 mutant clear cell renal cell carcinoma predicted - sensitive Nivolumab Clinical Study - Cohort Actionable In a clinical study, PBRM1 truncating mutations were associated with response to Opdivo (nivolumab) with 39% (15/38) of responding patients harboring PBRM1 mutations vs 22% (16/74) of non-responders, as well as clinical benefit (p=0.0497), increased progression-free survival (HR=0.67), and overall survival (HR=0.65) in post-hoc analysis of archival samples from a Phase III clinical trial of clear cell renal cell carcinoma patients (PMID: 31486842). 31486842
PBRM1 mutant lung non-small cell carcinoma predicted - resistant unspecified PD-1 antibody Clinical Study - Cohort Actionable In a clinical study, treatment with either an anti-PD-1 or anti-PD-L1 therapy resulted in a significantly shorter overall survival (p=0.0057) and progression-free survival (p=0.03) in patients with non-small cell lung cancer harboring a PBRM1 mutation compared to patients with wild-type PBRM1 (PMID: 36456601). 36456601
