Preliminary Results on MDNA55 and MDNA109 to be Presented at the Immuno-Oncology 360° Conference

TORONTO and HOUSTON, Jan. 24, 2019 /CNW/ - Medicenna Therapeutics Corp. ("Medicenna" or the "Company") (TSX: MDNA; OTCQB: MDNAF), a clinical stage immuno-oncology company, today announced two presentations at the Immuno-Oncology 360° Conference to be held February 6-8, 2019 at the Crowne Plaza Times Square, New York NY.

The details of the presentations are as follows:

Title:

The IL4 Receptor as a Biomarker and Immunotherapeutic Target for Glioblastoma: Preliminary Evidence with MDNA55, a Locally Administered IL-4 Guided Toxin

Presenter:

John H Sampson, MD, PhD, Robert H. and Gloria Wilkins Distinguished Professor and Chair of Neurosurgery, Department of Neurosurgery, Duke University School of Medicine

Date:  

Thursday February 7, 2019

Time:  

4:05 PM

 

The presentation will introduce the Interleukin-4 receptor (IL4R) as an ideal but under-exploited target for the development of cancer therapeutics as it is frequently and intensely expressed on a variety of human carcinomas and is associated with aggressive disease and poor survival outcomes. This talk will focus on MDNA55, a novel IL-4 targeted fusion toxin, administered intratumorally via MRI-guided convection enhanced delivery as a single treatment for recurrent Glioblastoma. The role of IL4R expression on survival outcomes and therapeutic benefit from MDNA55 treatment will be presented.

Title:     

Putting Pedal to the Metal: Combining IL-2 Superkine (MDNA109) with Checkpoint Inhibitors

Presenter:  

Moutih Rafei, PhD, Associate Professor, Department of Pharmacology and Physiology, Université de Montreal 

Date:  

Wednesday February 6, 2019

Time:  

11:40 AM

 

The presentation will cover the following:

  • A major limitation of interleukin-2 therapy approved for use in treatment of metastatic melanoma and renal cell carcinoma is its severe toxicity mediated by the IL-2 accessory receptor CD25
  • MDNA109 is an engineered IL-2 superkine exhibiting 1000-fold enhanced affinity toward the CD122 receptor and best in class potency toward effector T cells
  • Rationally engineered MDNA109 muteins with extended half-life and impaired CD25 binding activity bypass the off-target toxicity and unwanted stimulation of Treg by IL-2 and demonstrate impressive in vivo efficacy when combined with checkpoint inhibitors
