| In vitro | BI 7446 (CDN13) at concentrations of 3 μM and 10 μM over 6 hours enhances the phosphorylation of IRF3 and TBK1 in THP1 STING wild-type cells [1]. |
| In vivo | BI 7446 (CDN13) administered intravenously at doses of 4, 12, and 36 μg with detection time points up to 25 hours exhibited high plasma clearance and a short elimination half-life in the 4T1 tumor mouse model [1]. Similarly, subcutaneous injections of BI 7446 at 0.25, 1, and 4 μg once weekly resulted in tumor regression in the EMT breast cancer mouse model and generated long-term immune memory against autologous tumor rechallenge [1]. |
