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.

Molecular Profile Indication/Tumor Type Response Type Therapy Name Approval Status Evidence Type Efficacy Evidence References
PTEN negative Advanced Solid Tumor sensitive Talazoparib Preclinical - Cell culture Actionable In a preclinical study, PTEN-deficient cancer cell lines with DNA repair deficiency demonstrated high sensitivity to the PARP inhibitor Talzenna (talazoparib) (PMID: 23881923). 23881923
PTEN negative glioblastoma no benefit Temozolomide + Vandetanib Phase II Actionable In a Phase II trial, Caprelsa (vandetinib), in combination with radiation therapy and Temodar (temozolomide), demonstrated no difference in PFS and OS when compared between glioblastoma patients negative for PTEN versus those positive for PTEN (PMID: 25910950). 25910950
PTEN negative lung squamous cell carcinoma sensitive Buparlisib Phase II Actionable In a Phase II trial, one patient with Pten negative squamous NSCLC had a partial response to Buparlisib (BKM120) however, stage 2 of the study was not initiated due to failure of meeting overall stage 1 response endpoints (PMID: 26098748). 26098748
PTEN negative renal cell carcinoma predicted - sensitive Temsirolimus Clinical Study - Cohort Actionable In a clinical study, negative PTEN IHC staining were detected more frequently in patients with renal cell carcinoma who responded to treatment with Afinitor (everolimus) or Torisel (temsirolimus) (odds ratio = 0.24, p=0.029) than those who did not respond (PMID: 31335987). 31335987
PTEN negative renal cell carcinoma predicted - sensitive Everolimus Clinical Study - Cohort Actionable In a clinical study, negative PTEN IHC staining were detected more frequently in patients with renal cell carcinoma who responded to treatment with Afinitor (everolimus) or Torisel (temsirolimus) (odds ratio = 0.24, p=0.029) than those who did not respond (PMID: 31335987). 31335987
PTEN negative prostate cancer not predictive Niraparib Phase I Actionable In a Phase I trial, negative PTEN IHC staining was not associated with response to Zejula (niraparib) treatment in patients with castration-resistant prostate cancer (PMID: 23810788; NCT00749502). 23810788
PTEN negative glioblastoma no benefit Buparlisib + Capmatinib Phase Ib/II Actionable In a Phase Ib/II trial, combination of Buparlisib (BKM120) and Tabrecta (capmatinib) did not reach target exposure due to potential drug-drug interaction, and demonstrated minimal activity in patients with glioblastoma harboring PTEN alterations including deletion, mutation, or negative protein expression, therefore, Phase II of the trial was not initiated (PMID: 31776899; NCT01870726). 31776899
PTEN negative endometrial carcinoma no benefit Olaparib Preclinical - Cell culture Actionable In a preclinical study, Lynparza (olaparib) treatment did not significantly increase DNA damage or inhibit growth of PTEN-deficient endometrial carcinoma cell lines in culture (PMID: 28945226). 28945226
PTEN negative endometrial carcinoma sensitive Buparlisib Preclinical - Cell culture Actionable In a preclinical study, Buparlisib (BKM120) inhibited Akt signaling, induced DNA damage, and inhibited the growth of PTEN-deficient endometrial carcinoma cell lines in culture (PMID: 28945226). 28945226
PTEN negative endometrial carcinoma sensitive Buparlisib + Olaparib Preclinical - Cell culture Actionable In a preclinical study, the combination of Buparlisib (BKM120) and Lynparza (olaparib) resulted in enhanced DNA damage and growth inhibition in PTEN-deficient endometrial carcinoma cell lines in culture (PMID: 28945226). 28945226
