Medicenna Strengthens Intellectual Property Protection for Superkine Platform with Issuance of U.S. Patent
- Patent covers composition and methods of treating degenerative diseases via administration of IL-4 and IL-13 Empowered Superkines
- Delivery of selected Bcl-2 family of proteins can prevent cell death, repair cell damage and restore cellular function in various diseases.
“This latest patent strengthens our IP protection, diversifies our pipeline while underscoring the versatility of the Superkine platform,” said Dr. Fahar Merchant, President and CEO of Medicenna. “By utilizing directed evolution, the Superkine platform creates highly selective tunable cytokines that can be seamlessly integrated with a variety of additional therapeutic moieties. Anti-apoptotic Bcl-2 proteins are essential to maintain the integrity of mitochondria, which are powerhouses of every cell. This has allowed us to generate novel biologics targeting a broad spectrum of conditions such as autoimmune disorders and neurodegenerative diseases. Looking forward, we believe our robust IP portfolio and preclinical data leave us well positioned to pursue partnerships aimed at facilitating the advancement of these discovery-stage assets and enable us to generate value across several therapeutic areas while remaining primarily focused on oncology and our lead MDNA11 program.”
Increased programmed cell death, or apoptosis, is linked to the progression of a variety of degenerative diseases such as Alzheimer’s disease, Parkinson’s disease, stroke, muscular dystrophy, spinal cord injury and others. Medicenna’s IL-4/IL-13 Superkine empowered with Bcl-2 family of fusion proteins are designed to treat these and other degenerative diseases by delivering anti-apoptotic peptides to cells expressing IL-4 and IL-13 receptors.
The above patent expands on Medicenna’s Empowered Superkine Platform with 3 other issued patents related to delivery of Bcl-2 proteins via IL4/IL13 receptors (US Patent No. 10,106,592, US Patent No. 11,352,402, Japanese Patent No. 6661530). In addition, US Patent No. 10,781,242 covers composition and methods for IL-2 Superkine Bcl-2 fusions that can enhance immune cell survival for cancer therapy and expand engineered immune cells for adoptive cell transfer therapy.
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.
