Medicenna’s IL-2 Superkine Platform Featured in Peer-Reviewed Publication Demonstrating its Superiority and Ability to Reprogram the Tumor Microenvironment in Pancreatic Cancer
(GlobeNewswire)
- "Medicenna Therapeutics Corp...announced the peer-reviewed publication of preclinical data on MDNA109, the Company’s IL-2 Superkine platform that forms the basis for MDNA11....Treatment with MDNA109-virus led to superior tumor growth inhibition by showing a clear tendency towards complete tumor regression and improved survival; MDNA-109-virus weakened tumor-protecting myeloid cells in the tumor microenvironment (TME)."

[VIRTUAL] Emergence of novel long-acting mono- and bi-specific IL-2/IL-13 Superkines as potent immune modulators
(AACR-NCI-EORTC 2020)
- "Background: Use of IL-2 (Proleukin®) remains limited due to a short half-life, toxicity, and preferential activation of Tregs driven by a high affinity for IL2Rα over IL2Rβ. To bypass these limitations, we further engineered MDNA109, an IL-2 superkine, to generate MDNA11 by (1) addition of mutations to abrogate IL2Rα binding and (2) fusion with albumin to extend half-life... MDNA11 is a long-acting IL-2 superkine with superior potency at activation of naïve CD8 T cells and NK cells, and diminished activity on Tregs. MDNA11 potently inhibited growth of tumors and induced durable regression and strong memory response. Novel bispecific constructs also demonstrated efficacy in these in vivo tumor models."

Long-acting MDNA109 : Emerging IL-2 Superkines displaying potent anti-tumoral responses.
(CRI-CIMT-EATI-AACR 2019)
- "Background: Use of cytokines as cancer therapy was initiated with the approval of interleukin-2 (Proleukin®) for treatment of metastatic melanoma and renal cell carcinoma. MDNA109 is the only IL-2 in development that has been engineered for high affinity binding to CD122. Furthermore, three long-acting Superkines, MDNA109-LA, MDNA109-LA1, and MDNA109-LA2 have superior potency over IL-2 at activating NK and naïve CD8 effector T-cells. These 3 molecules potently inhibited CT26 and B16F10 tumor growth in vivo as monotherapies as well as in combination with ICIs on a dosing schedule that is similar to that of antibody based therapies."

Medicenna selects its lead immuno-oncology clinical candidate, MDNA19, from its IL-2 superkine platform
(PRNewswire)
- “Medicenna Therapeutics Corp….announced the selection of MDNA19 (formerly, MDNA109-LA1) as its second immuno-oncology clinical candidate for the treatment of cancer. MDNA19 is a best-in-class long-acting IL-2 developed from Medicenna's Superkine platform that has shown unique ability to selectively stimulate cancer killing immune cells without the limitations seen with other long-acting IL-2 programs….With IND-enabling studies expected to be completed next year, Medicenna expects to enter clinical studies with MDNA19 in 2020.”

Medicenna presents new preclinical results for its IL-2 superkine platform, MDNA109
(PRNewswire)
- “When MDNA109-LA was co-administered with the immune-checkpoint blocker anti-cytotoxic T-Lymphocyte-Associated Protein (CTLA)4 in a colon cancer mouse model, 67% of animals with pre-established tumors remained tumor-free for over 100 days. When these animals received a second and third re-challenge of the tumor without further treatment, 100% and 75% remained tumor free, respectively, demonstrating a strong memory response….Data show that MDNA109-LA1 may not only minimize adverse effects, but could also eliminate immunosuppression caused by Tregs using a dosing schedule that is compatible with immune-checkpoint blockers.”
