Biological Activity

BLU-945 (ZL-2313, BLU945, BLU 945) is a potent, mutant-selective inhibitor of EGFR T790M/C797S and EGFR+/T790M mutations (IC50<1 nM).
BLU-945 inhibits EGFRex19del/T790M/C797S, EGFRL858R/T790M/C797S, EGFRex19del/T790M, and EGFRL858R/T790M mutants with sub-nanomolar IC50 values in an enzyme assay, with >1000-fold selectivity over EGFR WT.
BLU-945 achieves potent EGFR pathway inhibition in NCI-H1975 EGFRL858R/T790M, Ba/F3 EGFRL858R/T790M/C797S, and Ba/F3 EGFRex19del/T790M/C797S cell lines and a large window relative to EGFRWT inhibition.
Oral administration of BLU-945 to tumor-bearing mice demonstrated potent EGFR pathway inhibition and anti-tumor activity at well-tolerated doses in the subcutaneous NCI-H1975 CDX model, and osimertinib-resistant CDX and PDX models.
