Cambridge, UK; 22 June 2020: Kymab, a clinical-stage biopharmaceutical company developing antibody-based therapeutics, today announced that e-posters relating to Kymab's lead immune-oncology programs, KY1044 and KY1043, will be presented at the American Association for Cancer Research ("AACR") Virtual Annual Meeting II, being held June 22-24, 2020.   

The e-posters are available on the AACR website; the details are as follows:

Abstract # 2134

Title: High ICOS/FOXP3 Tregs content in the tumor microenvironment is associated with poorer survival in patients with hepatocellular carcinoma

Session Type:               Poster Session

Session Category:       Tumor Biology

E-Poster Number:        1590  

Abstract # 2780

Title: KY1043, a novel CD25-directed PD-L1 IL-2 immunocytokine, delivers potent anti-tumor activity in vivo via an expansion of a Tcf1hi PD-1+ CD8+ T cell population

Session Type:              Poster Session

Session Category:      Therapeutic Antibodies 3

E-Poster Number:       4542   

KY1044 is a human monoclonal IgG1 that selectively binds to Inducible T cell CO-stimulator (ICOS), a protein expressed at high levels on immunosuppressive regulatory T cells and at lower levels on effector T cells. KY1044 is designed to exert anti-tumor activity through preferential depletion of intra-tumoral regulatory T cells and stimulation (agonism) of ICOS-positive effector T cells. A Phase 1/2 clinical trial of KY1044 in patients with advanced solid tumors as a monotherapy and in combination with an anti PD-L1 (atezolizumab) is ongoing.  

KY1043 is a human monoclonal antibody that provides targeted immune checkpoint inhibition coupled with dose-dependent anti-tumor activity by combining Kymab’s proprietary PD-L1 blocking antibody and a reduced potency, or attenuated, version of the cytokine IL-2 in a single immunocytokine. KY1043 is designed to block immunosuppressive "checkpoint" signals, to allow the immune system to recognize and kill tumors while also localizing IL-2 delivery. These combined activities should increase immune cell recruitment and expansion and anti-tumor activity in the tumor microenvironment.
