MARTINSRIED, Germany and MUNICH, Germany, Nov. 15, 2022 (GLOBE NEWSWIRE) -- Medigene AG (Medigene, FSE: MDG1, Prime Standard), an immuno-oncology company focused on the development of differentiated, best-in-class T Cell Receptor engineered T cell (TCR-T) therapies, today announces an updated corporate strategy to drive and expedite the development of novel therapies for the treatment of multiple solid tumor indications with high unmet need.

“We are excited to announce this strategy and corporate update for Medigene,” said Dr. Selwyn Ho, MB BS, Chief Executive Officer at Medigene. “At the heart of our work is our extensive expertise on T cell immunology and many years of development of a proprietary, innovative “end-to-end” platform under the leadership of our Chief Scientific Officer, Prof. Dolores Schendel.

With the platform containing multiple combinable technologies that optimize the development of, as well as enhance the TCR-T products from both an activity and potential safety perspective, we believe that our emerging TCR-T therapies have the potential to address the significant challenges that solid tumors create for immunotherapies, and improve clinical outcomes. The robustness of our work has been well validated through multiple partnerships where potentially highly differentiated TCRs and novel individual technologies have been licensed from Medigene, as well as through the success of our MDG1011 phase 1 trial.

We are focused on delivering best-in-class TCR-T therapies to patients suffering from difficult to treat tumors and have accelerated and prioritized our research activities. Our lead program, MDG1015, is a 3rd generation TCR-T therapy that combines a novel TCR against NY-ESO-1, a well-characterized and validated cancer antigen expressed in multiple tumor types, with the PD1-41BB Switch Receptor that significantly improves the ability of our TCR-T cells to kill cancer cells. This program has the potential for a more targeted, safer, and potent immune response while overcoming highly immunosuppressive tumor microenvironment.

To support our efforts, we continue to strengthen our leadership team and have appointed Mr. James Cornicelli as Head of Corporate Development and Strategy. As a highly seasoned executive with over 20 years in senior business development and strategic advisory roles, Mr. Cornicelli brings multiple areas of expertise that will help guide our company on critical decisions about partnering and accelerate our growth strategy.”

Strategic Actions Summary:

• TCR-T Therapies Central to Medigene’s Approach
  

Medigene’s strategy will focus on developing best-in-class T Cell Receptor engineered T cell (TCR-T) therapies. TCR-T therapies are a novel class of cellular immunotherapy with the ability to engage both surface and intracellular antigens on target cells, unlike CAR-T cell-based therapies, allowing for solid tumor targeting in a highly specific manner. The first generation of TCR-T therapies have shown improvements in outcomes in solid tumor clinical trials; however, unmet needs remain for further improvements in efficacy, that are sustained and with a lower risk of adverse effects.

• Pipeline Expansion and Acceleration of Discovery Programs MDG1015 and MDG10xx
  

MDG1015, the company’s lead program, consists of a novel TCR against NY-ESO-1 (New York esophageal squamous cell carcinoma 1), a well-characterized cancer testis antigen (CTA) expressed in multiple tumor types combined with our PD1-41BB Switch Receptor technology, which blocks the PD1/PD-L1 inhibitory axis between T cells and tumors and activates the 41BB co-stimulatory pathway in TCR-T cells. This co-stimulation and reduced inhibition, help mitigating the negative effects of the solid tumor microenvironment, leading to multiple improvements in the activity of MDG1015, including improved tumor cell killing, greater effector T cell function, and enhanced T cell proliferation. For MDG1015 we expect a CTA / IND filing in 2H 2024.

MDG10xx is our second newly announced TCR-T therapy program against several undisclosed targets, in combination with the PD1-41BB Switch Receptor technology. The selection of a lead candidate for MDG10xx is planned for the second half of 2023.

• Advancing Broad, Proprietary “End-to-End” Platform
  

Medigene’s “end-to-end” platform provides multiple combinable, exclusive, and proprietary technologies to create potential best-in-class TCR-T therapies to address the unmet needs in the treatment of solid tumors. The platform includes technologies that both help optimize our development activities as well as to enhance our TCR-T therapy products, during the stages of target screening, TCR generation, TCR-Therapy optimization, manufacturing, and clinical development. These include:

• EXPItope-M: Proprietary in silico tool to identify immunogenic epitopes as potential TCR target specificities.
  
• Allo-HLA TCR priming technology: Generation of high-affinity natural TCRs, for improved sensitivity and safety, by bypassing the thymic selection
  
• CrossTAg vector system: Technology loads antigen on both HLA Class I and Class II complexes in antigen-presenting cells (APCs), creating stronger and more sustained immune responses
  
• JOVI-Tag: Tool allowing standardized enrichment and tracking of recombinant TCR (rTCR) -expressing T cells to enable selection of safer TCRs when using HTS
  
• PD1-41BB Co-Stimulatory Switch Receptor: A novel, highly innovative receptor that enhances TCR-T cell functionality, enabling it to mitigate against immunosuppressive tumor microenvironment (TME) and improves efficacy and sustained immune responses
  
• Precision Pairing: Enables the modification and tailoring of TCR constant regions to improve pre-clinical efficacy through the enhanced anti-tumor functional activity of TCR-T cells and potential for improved safety by reducing the potential for off-target effects
  
• Inducible iM-TCR: Control mechanism to regulate TCR-T therapy efficacy & safety, to avoid T cell exhaustion, cell death, and a loss of efficacy as well as to prevent over-activation of TCR-T which can mediate inflammatory responses in off-target tissues
  

Medigene is also currently developing additional novel and complementary technologies to add to our platform that will further optimize the development of and continue to enhance our TCR-T therapies.

• Strengthening & Expanding our Partnership Approach By Leveraging our Innovative Assets & Technologies
  

To date, multiple partnerships have been established that validate our “end-to-end” platform assets and technologies, including with BioNTech, 2SeventyBio, and Hongsheng Sciences. Medigene will continue to work closely with our existing partners and explore new partnership opportunities to maximize the value of our current and future assets and technologies and ultimately deliver novel and differentiated TCR-T therapies to patients.

• Focus on Solid Tumors
  

As previously announced, we have successfully completed our phase 1 MDG1011 program in patients with acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), and multiple myeloma (MM). The MDG1011 trial provides clear clinical validation of our ability to generate and manufacture TCR-T therapies and details of our manufacturing process have been shared at the Cell UK meeting in London, in November 2022 with the presentation available on Medigene’s website. The expanded clinical dataset from the trial will be available in due course.

Despite this positive trial for MDG1011, as previously disclosed, we have focused any further research and development efforts towards solid tumors. The company is accelerating our plans to identify a suitable strategic partner and will provide an update in due course.

About Medigene’s TCR-T cells

T cells are at the center of Medigene’s therapeutic approaches. Medigene’s immunotherapies help activate the patient’s own defense mechanisms, and harness T cells in the battle against cancer. Medigene’s therapies arm the patient’s own T cells with tumor-specific T cell receptors (TCRs) creating TCR-modified T cells with enhanced potential to detect and efficiently kill cancer cells.

Medigene’s approach to immunotherapy is designed to overcome the patient’s tolerance of cancer cells and tumor-induced immunosuppression. By activating the patient’s T cells outside the body, genetically modifying them with tumor-specific TCRs and expanding the resultant activated TCR-T cells, patients can rapidly be given large numbers of tumor-specific T cells to fight their cancer.
