TORONTO and HOUSTON, April 09, 2024 (GLOBE NEWSWIRE) -- Medicenna Therapeutics Corp. (“Medicenna” or the “Company”) (TSX: MDNA), a clinical-stage immunotherapy company focused on the development of Superkines, today announced new preclinical data on MDNA113, the Company’s novel T-MASK (Targeted Metallo/protease Activated SuperKine) candidate, an IL-13R⍺2 (Interleukin-13 receptor alpha2) specific superkine featuring unique masking and tumor targeting characteristics, were presented at the 2024 Annual Meeting of the American Association for Cancer Research (AACR) held in San Diego, CA, on April 9th, 2024.
- Key findings presented at the conference include:
When not activated, MDNA113 shows reduced IL-2R agonism with no change to PD-1/PDL-1 blockade activity. - MDNA113 selectively binds IL-13R⍺2 positive tumor cells in vitro, and durably accumulates (>7 days) in IL-13R⍺2 positive tumors in mice.
- Single neoadjuvant treatment with MDNA113 in a highly invasive orthotopic 4T1.2 breast cancer model significantly increases survival by preventing metastasis.
- It will be also available on the Scientific Presentations page of Medicenna’s website following the conclusion of the 2024 Annual Meeting of AACR.
