Therapy Name LXH 254
Synonyms
Therapy Description

LXH 254 is a RAF inhibitor that selectively inhibits monomeric and dimerized BRAF and CRAF, which may lead to anti-tumor activity in RAF-mutant tumors and better tolerability (AACR Annual Meeting 2019, Abstract LB-114).

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.

Molecular Profile Indication/Tumor Type Response Type Therapy Name Approval Status Evidence Type Efficacy Evidence References
BRAF loss NRAS Q61K melanoma decreased response LXH 254 Preclinical - Cell culture Actionable In a preclinical study, CRISPR-Cas9 mediated knockout of BRAF in a melanoma cell line harboring NRAS Q61K led to decreased sensitivity to LXH254 treatment compared to parental cells harboring BRAF D287H and NRAS Q61K in culture (PMID: 33355204). 33355204
BRAF mutant Advanced Solid Tumor predicted - sensitive LXH 254 Case Reports/Case Series Actionable In a Phase I trial, LXH 254 treatment resulted in partial response in 2.6% (2/75) and stable disease in 33% (25/75) of patients with advanced solid tumors harboring MAPK pathway alterations, one of the patient achieved partial response harbored a BRAF mutation (J Clin Oncol 36, no. 15_suppl (May 20 2018) 2586-2586; NCT02607813). detail...
BRAF G469A lung adenocarcinoma sensitive LXH 254 Preclinical - Patient cell culture Actionable In a preclinical study, cells derived from a lung adenocarcinoma patient harboring BRAF G469A were sensitive to treatment with LXH 254 in culture, demonstrating inhibition of cell growth (PMID: 32540409). 32540409
BRAF V600E melanoma predicted - sensitive LXH 254 Preclinical - Cell line xenograft Actionable In a preclinical study, a melanoma cell line harboring BRAF V600E was sensitive to treatment with LXH254, demonstrating inhibition of cell proliferation in culture, and inhibition of tumor growth in a cell line xenograft model of melanoma (PMID: 33355204). 33355204
BRAF D287H NRAS Q61K melanoma predicted - sensitive LXH 254 Preclinical - Cell line xenograft Actionable In a preclinical study, a melanoma cell line harboring BRAF D287H and NRAS Q61K was sensitive to treatment with LXH254, demonstrating inhibition of cell proliferation in culture, and inhibition of tumor growth in a cell line xenograft model of melanoma (PMID: 33355204). 33355204
