Poster Title: An ‘Anti-PD1-IL2 Beta-Only Super-Agonist’ Displays Potent Anti-Tumor Efficacy

Session Category: Immunology

Session Title: Preclinical Immunotherapy

Location: On-line only

Abstract Number: 5532

This poster will describe preclinical studies evaluating a therapeutic candidate derived from Medicenna’s BiSKITs™ program (Bifunctional SuperKine ImmunoTherapies). The evaluated bifunctional Superkine is designed to activate anti-cancer immune cells while limiting their exhaustion, and is composed of an anti-PD-1 antibody linked to an IL-2 Superkine exhibiting enhanced affinity for IL-2 receptor beta, and no binding to IL-2 receptor alpha.

Poster Title: Characterization of a Long-Acting IL-13 Super-Antagonist Engineered to Target Tumor Associated Macrophages and Myeloid Cells

Session Category: Immunology

Session Title: Preclinical Immunotherapy

Location: On-line only

Abstract Number: 5542

This poster will describe preclinical studies evaluating a long-acting IL-4/IL-13 super-antagonist that targets the IL-13 receptor alpha-1 component of type II IL-4 receptor expressed on tumor associated macrophages and myeloid derived suppressor cells. Inhibition of this receptor with the super-antagonist is intended to prevent tumor growth by promoting a pro-inflammatory tumor microenvironment.

About Medicenna
Medicenna is a clinical stage immunotherapy company focused on the development of novel, highly selective versions of IL-2, IL-4 and IL-13 Superkines and first in class Empowered Superkines. Medicenna's long-acting IL-2 Superkine, MDNA11, is a next-generation IL-2 with superior CD122 (IL-2 receptor beta) binding without CD25 (IL-2 receptor alpha) affinity thereby preferentially stimulating cancer killing effector T cells and NK cells. Medicenna’s early-stage BiSKITs™ program, (Bifunctional SuperKine ImmunoTherapies) is designed to enhance the ability of Superkines to treat immunologically “cold” tumors. Medicenna's IL-4 Empowered Superkine, MDNA55, has been studied in 5 clinical trials including a Phase 2b trial for recurrent GBM, the most common and uniformly fatal form of brain cancer. MDNA55 has obtained Fast-Track and Orphan Drug status from the FDA and FDA/EMA, respectively.
