(“Medicenna” or the “Company”) (TSX: MDNA, OTCQB: MDNAF), a clinical-stage immunotherapy company developing Superkines for cancer and autoimmune diseases, today announced that it will present new preclinical data on MDNA209, its potential first-in-class cytokine-based CD122 superantagonist, at The Promises of Treg and Interleukin-2 Therapies Conference, taking place October 21–24, 2026, in Paris, France.This advertisement has not loaded yet, but your article continues below.The landscape of CD122 therapy (targeting the beta subunit of the IL-2 and IL-15 receptors) has demonstrated growing clinical validation and increasing strategic interest for the treatment of autoimmune and inflammatory conditions such as celiac disease, eosinophilic esophagitis, graft-versus-host-disease, and vitiligo.Get the latest headlines, breaking news and columns.By signing up you consent to receive the above newsletter from Postmedia Network Inc.A welcome email is on its way.

Please try againMDNA209 is an engineered protein designed to block CD122 and inhibit signaling by IL-2 and IL-15, two immune signaling molecules that can sustain the hyperactivity of immune cells responsible for inflammation and tissue damage. The upcoming presentation will further characterize MDNA209’s potency and its differentiated approach to targeting these pathways.Title: MDNA209 is a High Affinity CD122 Clamp that Functions as an IL-2/IL-15 Super-antagonist for the Treatment of Autoimmune DiseasesPresenter: Dr. Minh D. ToDate and Time: Friday, October 23rd 2026, 4:30-5:00 PM CESTCD122, also known as IL-2 receptor beta, is a shared signaling component of the receptors for IL-2 and IL-15. These interleukins help regulate the activation, growth and survival of immune cells. In certain autoimmune diseases, these pathways can sustain hyperactive immune cells that attack healthy tissues. Blocking CD122 offers an approach to inhibit IL-2 and IL-15 pathways through a single target. Recent clinical results reported with investigational CD122-blocking antibodies have supported growing interest in this mechanism as a potential treatment strategy for autoimmune diseases.This advertisement has not loaded yet, but your article continues below.MDNA209 is an investigational, long-acting superkine in preclinical development as a potential first-in-class cytokine-based CD122 superantagonist. MDNA209 is engineered for high-affinity binding to CD122, and is further designed to potently inhibit signaling by both IL-2 and IL-15, thereby suppressing immune cell activity that contribute to autoimmune and inflammatory diseases.About Medicenna TherapeuticsMedicenna is a clinical-stage immunotherapy company developing engineered cytokine therapies designed to selectively engage the immune system to treat cancer and autoimmune diseases. The Company’s most advanced program, bizaxofusp (formerly MDNA55), is a targeted IL-4 Empowered Superkine that has been evaluated in more than 130 patients across five clinical trials, including a Phase 2b study in recurrent glioblastoma. Bizaxofusp has received Fast Track designation from the FDA and Orphan Drug designation in the United States and Europe. Medicenna is also advancing MDNA11, a long-acting IL-2 Superkine designed to selectively activate cancer-fighting immune cells, which is currently being evaluated in the Phase 1/2 ABILITY-1 study and the Phase 1b NEO-CYT study. With its proprietary BiSKIT and T-MASK platforms, the Company is also developing MDNA113, a targeted PD-1 x IL-2 bifunctional immunotherapy for solid tumors, and MDNA209, an IL-2/IL-15 superantagonist effectively blocking the overactive CD122/CD132 pathway responsible for autoimmune diseases.This advertisement has not loaded yet.This advertisement has not loaded yet, but your article continues below.For more information, please visit www.medicenna.com, and follow us on X and LinkedIn.Forward-Looking StatementsThis news release contains forward-looking statements within the meaning of applicable securities laws.
