SOA101

SOA101 (Nanobody-based trispecific T cell engager, Nb-TriTE)

SOA101 was developed as a nanobody-based trispecific T cell engager (Nb-TriTE), capable of simultaneously binding to T cells, macrophages, and cancer cells while redirecting T cells towards tumor cells expressing PD-L1- and/or HLA-G. Nb-TriTE showed broad spectrum anti-tumor effects in vitro by augmenting cytotoxicity mediated by human peripheral blood mononuclear cells (PBMCs). In a humanized murine non-small cell lung cancer (NSCLC) model, Nb-TriTE exhibited superior anti-cancer potency compared to monoclonal antibodies and bispecific T cell engagers (BiTE). Nb-TriTE at the dose with pharmacoactivity did not induce additional enhancement of circulating cytokines secretion.

 


Product Introduction

Highlights

▪ Targets two anti-tumor ICPs on tumor cells, and used for T cell redirecting

▪ The nanobodies are connected and fused with human IgG1 Fc domain

▪ Fc domain is designed for prolonging the half-life of Nb-TriTE

▪ Enhances the integrity of tumor cells and T cells

▪ Conquers the immune-suppressive cold- to hot-tumor microenvironment

▪ Triggers T cell proliferation and activation

▪ Facilitates antibody-dependent cell cytotoxicity

 

 


Achievement1

 

Nb-TriTE suppresses NSCLC tumor growth and extends survival in humanised xenograft mice. (A) Treatment protocols for animal studies comparing the anti-cancer efficacy of Nb-TriTE and commercial monoclonal antibodies. (B) Tumor size was monitored and recorded weekly using the representative in vivo imaging system (IVIS). Tumor changes were quantified as growth inhibition (TGI). (C) The survival rate of mice was plotted using the Kaplan–Meier method. ***p<0.001.
