A Study of Bispecific Antibody MCLA-158 in Patients With Advanced Solid Tumors

ABSTRACT: This is a Phase 1/2 open-label, multi-center, multi-national study with an initial dose escalation part to determine the RP2D of MCLA-158 single agent in patients with mCRC. The dose escalation part has been completed and the RP2D will be further evaluated in an expansion part of the study. Cohorts of selected solid tumor indications for which there is evidence of EGFR dependency and potential sensitivity to EGFR inhibition will be evaluated. The study will further assess the safety, tolerability, PK, PD, immunogenicity, and anti-tumor activity of MCLA-158.

Project description:EGFR is a critical regulator of hepatocyte proliferation and liver regeneration. Our recent work indicated EGFR can also regulate lipid metabolism during liver regeneration after partial-hepatectomy. Based on these findings, we investigated role of EGFR in a mouse model of NAFLD utilizing a pharmacological inhibition strategy. C57BL6/J mice were fed chow-diet, or fast-food diet with/without EGFR inhibitor (Canertinib) for 2-months. EGFR inhibition completely prevented development of steatosis and liver injury in this model. In order to study if EGFR inhibition can reverse NAFLD progression, mice were fed fast-food diet for 5-months, with/without Canertinib-treatment for the last 5-weeks of the study. EGFR-inhibition remarkably decreased steatosis, liver injury, fibrosis and improved glucose tolerance. Microarray analysis revealed ~40% of genes altered by fast-food diet were differentially expressed after EGFR-inhibition, and thus, are potentially regulated by EGFR. Several genes and enzymes related to lipid metabolism (particularly fatty-acid synthesis and lipolysis), which were disrupted by fast-food diet, were found to be modulated by EGFR. Several crucial transcription factors that play a central role in regulating these lipid metabolism genes during NAFLD, including PPARγ, SREBF1, ChREBP and HNF4α, were also found to be modulated by EGFR. In fact, ChIP-analysis revealed PPARγ binding to several crucial lipid metabolisms genes (Fasn, Scd1 and Plin2) was drastically reduced by EGFR inhibition. Further upstream, EGFR-inhibition suppressed AKT signaling, which is known to control these transcription factors, including PPARγ and SREBF1, in NAFLD models. Lastly, the effect of EGFR in FFD-induced fatty-liver phenotype was not shared by receptor-tyrosine-kinase MET, as investigated using MET-KO mice. In-conclusion, our study revealed a role of EGFR in NAFLD and the potential of EGFR-inhibition as a treatment strategy for NAFLD. We used microarrays to detail the global programme of gene expression in liver of C57BL6/J mice fed fast-food diet mice treated with EGFR inhibitor (canertinib)
