Excerpt:
...two PDXs of BLBC origin with pathogenic BRCA1 alterations: BRCA1 R1443* mutation and truncating BRCA1 2080delA mutation. Following tumor implantation and expansion, each model was treated with daily gavage of 50 mg/kg olaparib (a PARP inhibitor) and 25 mg/kg fadraciclib (sub-optimal doses selected for combination testing) (Fig. 6a). In the BRCA1 R1443* mutant PDX, single agent olaparib led to reduced tumor burden and increased overall survival...
