| Description | BI-4142 is a potent, highly selective and orally active HER2 inhibitor with an IC50= 5 nM. BI-4142 showed efficacy against HER2 exon 20 insertion-driven tumors, while preserving EGFR wt signaling. | | Uses | BI-4142 is a potent, highly selective and orally active HER2 inhibitor with an IC50 of 5 nM[1]. | | in vivo | BI-4142 (0-100 mg/kg; p.o.; twice per day for 40 days) inhibits tumor growth and inhibits oncogenic signaling[1]. | Animal Model: | NMRI-Foxn1nu mice, PC-9 HER2YVMA xenograft model[1] | | Dosage: | 3, 10, 30 and 100 mg/kg | | Administration: | Oral administration, twice per day for 40 days | | Result: | Resulted in tumor regressions in a dose-dependent manner (113%, 126%, 153% and 166% tumor growth inhibition at 3, 10, 30 and 100 mg/kg, respectively). |
| Animal Model: | BomTac:NMRI Foxn1nu mice[1] | | Dosage: | 1 mg/kg or 10mg/kg and 100 mg/kg | | Administration: | IV for 1 mg/kg, PO for 10mg/kg and 100 mg/kg (Pharmacokinetic Analysis) | | Result: | In vivo mouse PK data for BI-4142[1]
