BI-1622 shows high antitumor efficacy in vivo in xenograft mouse tumor models with engineered H2170 and PC9 cells and had a favorable agent metabolism and pharmacokinetics profile[1].

In Vitro

BI-1622 (0-5 µM, 72 h or 96 h) inhibits the proliferation of HER2-dependent cell lines[1].
BI-1622 induces a dose-dependent decrease in pHER2 and pERK levels in NCI-H2170 HER2YVMA and PC-9 HER2YVMA cells with an accompanying decrease in DUSP6 messenger RNA levels[1].
BI-1622 displays good permeability and no PgP-mediated efflux liability[1].
BI-1622 shows good in vitro clearance in mouse liver microsomes and mouse hepatocytes[1].

Cell Proliferation Assay[1]

Cell Line: Ba/F3 cells
Concentration: 0-5 µM
Incubation Time: 72 h or 96 h
Result: Potently inhibited the proliferation of cancer cell lines dependent on amplified HER2 or an NRG-1 fusion. Inhibited different HER2 oncogenic variants and HER2WT with IC50 values below 50 nM in tumor cell lines, while sparing EGFRWT-driven cells.
In Vivo

BI-1622 (1 mg/kg, IV; 10 and 100 mg/kg, Orally; once) shows moderate clearance, a moderate volume of distribution, and good to moderate bioavailability[1].
BI-1622 (0-100 mg/kg, orally, twice daily) inhibits tumor growth and inhibits oncogenic signaling in vivo[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Female NMRI-Foxn1nu mice (6-8 weeks old, 8-10 mice per cage, engrafted subcutaneously with PC-9 HER2YVMA, NCI-H2170 HER2YVMA or NCI-N87 cells)[1]
Dosage: 10, 30 and 100 mg/kg
Administration: orally, twice daily
Result: In the NCI-H2170 HER2YVMA mechanistic model, 100 mg/kg twice daily BI-1622 resulted in a delay in tumor growth (73% TGI). In the ST3107 HER2 exon 20 mutant model, both BI-4142 (100 mg/kg twice daily) resulted in tumor regressions.
Animal Model: NMRI Foxn1nu mice (n=3 per group)[1]
Dosage: 1 mg/kg (IV); 10 and 100 mg/kg (Orally)
Administration: IV, Orally; once (Pharmacokinetic Analysis)
Result: Showed moderate in vivo clearance (50% hepatic blood flow), a moderate volume of distribution, and good to moderate bioavailability of up to 68%.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
