Deciphering the Antitumor Potential of BI 836845: A Human IGF-Neutralizing Antibody

3 June 2024
The IGF signaling pathway is crucial in tumor development and resistance to cancer treatments. A new antibody, BI 836845, has been engineered to target IGF-1 and IGF-2, which are key in this signaling process. This human IgG1 monoclonal antibody exhibits high affinity for both human and rodent IGF-1 and IGF-2, facilitating comprehensive preclinical studies. BI 836845 effectively neutralizes the phosphorylation of the IGF-1R by IGF-1 and IGF-2, as well as the phosphorylation of IR-A by IGF-2. It also inhibits IGF bioactivity in human serum samples.

In a pharmacodynamic study involving growing rats, BI 836845 showed inhibition of IGF bioactivity at various dosages, leading to a significant reduction in body weight gain. This suggests that the antibody affects the IGFs' role in growth and development. Additionally, BI 836845 demonstrated a strong inhibitory effect on the proliferation of various cancer cell lines, with mesenchymal-derived cells showing particular sensitivity.

In a study on Ewing's sarcoma using mice, BI 836845 partially inhibited tumor growth when administered twice weekly. The combination of BI 836845 with rapamycin enhanced the therapeutic effect at tolerable doses. Overall, BI 836845 is a potential candidate for clinical trials due to its ability to neutralize IGF ligands effectively.
