About Transgene
Transgene (Euronext: TNG) is a biotechnology company focused on designing and developing virus-based targeted immunotherapies and vaccines. The Company’s clinical-stage programs consist of a portfolio of viral vector-based immunotherapeutics. Transgene’s myvac® platform is designed to develop individualized neoantigen therapeutic vaccines (INTVs), with potential across multiple solid tumor types.
TG4050, the first INTV based on the myvac® platform is the Company’s lead asset, with demonstrated clinical proof of principle in the adjuvant treatment of head and neck cancer. TG4070, the second myvac®-based INTV introduces Transgene’s proprietary AI-driven neoantigen selection and scalable cell-line manufacturing capabilities and is in Phase 1 clinical development in combination with nivolumab in the adjuvant treatment of non-small cell lung cancer (NSCLC). The Company’s other viral vector-based assets include BT-001, an oncolytic virus based on the Invir.IO® viral backbone, which is in clinical development. Transgene also conducts innovative discovery and preclinical work, aimed at developing novel viral vector-based modalities.
With Transgene’s myvac® platform, therapeutic vaccination enters the field of precision medicine with an immunotherapy tailored to each individual patient. The myvac® approach enables the generation of virus-based immunotherapies encoding patient-specific neoantigens. Transgene has further expanded the platform’s capabilities with its own proprietary AI-driven neoantigen selection and scalable cell-line manufacturing.
Leveraging its MVA and cell-line manufacturing expertise, Transgene is developing TG-MVA™, a next-generation prophylactic vaccine candidate against mpox and smallpox designed to address key manufacturing and supply challenges.
Transgene is building on its viral vector engineering expertise to design a new generation of multifunctional oncolytic viruses.
