Transgene and ProBioGen Join Forces to Advance Individualized Cancer Vaccine Development

Strasbourg (France), Berlin (Germany), November 5, 2024, 7:30 a.m. CET—Transgene (Euronext Paris: TNG), a biotech company that designs and develops virus-based immunotherapies for the treatment of cancer, and ProBioGen, a leading CDMO in biologics, vaccines and viral vectors, announce that the companies have entered into a license agreement for ProBioGen’s AGE1.CR.pIX® suspension cell line. This partnership aims to add value by combining ProBioGen’s specific production technology with the manufacturing capabilities of Transgene’s individualized cancer vaccine program and its myvac® platform.

ProBioGen’s AGE1.CR.pIX suspension cell line showcases innovation and reliability in bioprocessing with a proven track record and is currently in use for multiple late-stage clinical trials. Renowned for its high yield and scalability, this platform enables efficient industrial manufacturing processes, translating into cost-effectiveness and increased productivity in manufacturing. Additionally, the AGE1.CR.pIX cell line offers robust growth and excellent genetic stability to ensure consistent and reliable production.

“We are delighted to embark on this collaborative journey with ProBioGen,” said Dr. Alessandro Riva, CEO of Transgene. “The AGE1.CR.pIX suspension cell line represents a significant addition to further expand the manufacturing processes for our individualized cancer vaccines while we work towards providing patients with tailored patient-specific therapies against cancer on a larger scale.”

The partnership between Transgene and ProBioGen underscores a shared commitment to advancing the field of individualized medicine and to support manufacturing scalability and optimization.

“We are thrilled to partner with Transgene in advancing the frontier of personalized cancer vaccines,” said Dr. Volker Sandig, CSO of ProBioGen. “Our collaboration holds immense potential to impact the personalized vaccine space and to offer new treatments and hope to cancer patients.”

About Transgene
Transgene (Euronext: TNG) is a biotechnology company focused on designing and developing targeted immunotherapies for the treatment of cancer. Transgene’s programs utilize viral vector technology with the goal of indirectly or directly killing cancer cells.
The Company’s clinical-stage programs consist of a portfolio of therapeutic vaccines and oncolytic viruses: TG4050, the first individualized therapeutic vaccine based on the myvac® platform, TG4001 for the treatment of HPV-positive cancers, as well as BT-001 and TG6050, two oncolytic viruses based on the Invir.IO® viral backbone. With Transgene’s myvac® platform, therapeutic vaccination enters the field of precision medicine with a novel immunotherapy that is fully tailored to each individual. The myvac® approach allows the generation of a virus-based immunotherapy that encodes patient-specific mutations identified and selected by Artificial Intelligence capabilities provided by its partner NEC.
With its proprietary platform Invir.IO®, Transgene is building on its viral vector engineering expertise to design a new generation of multifunctional oncolytic viruses.
