Collaboration to Evaluate the Combination of Transgene�s Oncolytic Virus and PersonGens CAR-T Cells in Preclinical Models
STRASBOURG, France & SUZHOU, China–(BUSINESS WIRE)–Regulatory News:
Transgene (Euronext Paris: TNG) (Paris:TNG), a biotech company that designs and develops virus-based immunotherapeutics against cancer, and PersonGen BioTherapeutics, a Chinese biotech company at clinical trial stage, which is developing breakthrough and innovative CAR-T cell therapies for solid tumors and hematologic tumors, today announced a strategic collaboration to evaluate the feasibility and efficacy of combination therapy associating PersonGen’s TAA06 CAR-T cell injection with intravenous (IV) administration of an armed oncolytic virus, from Transgenes Invir.IO platform, in solid tumors including pancreatic cancer and brain glioma. The collaboration aims to demonstrate the combinations likely synergistic mechanisms to potentiate CAR-T cell therapy.
Under the terms of the collaboration agreement, Transgene will develop multiple new OV candidates, using its patented oncolytic virus backbone VVcopTK–RR– and its Invir.IO technology platform, specifically for IV administration in combination with PersonGen’s TAA06 CAR-T injection. PersonGen will evaluate the efficacy of the combination to eliminate solid tumors in preclinical models.
While CAR-T cell drugs have achieved great success in the treatment of hematological tumor therapies, there are many clinical challenges with the use of these novel therapies to treat solid tumors. One of the most critical obstacles is that the solid tumor microenvironment not only obstructs the homing of CAR-T cells, but also inhibits CAR-T cells’ function. In addition, the high heterogeneity of solid tumors also facilitates immune escape from CAR-T cell therapy.
TAA06, has been independently developed by PersonGen, which has filed an investigational new drug (IND) application for this novel CAR-T therapy in China and will initiate the IND in the US later this year. Preclinical studies with TAA06, including pharmacodynamic data have shown superior in vivo and in vitro therapeutic efficacy in solid tumors.
Patented VVcopTK–RR– oncolytic viruses developed with Transgenes Invir.IO platform are able to:
Clinical and preclinical data has demonstrated that after IV administration, VVcopTK–RR– oncolytic viruses selectively replicate and persist in tumor cells leading to the local expression of its functional payload1.
Based on these highly supportive data, Transgene and PersonGen believe that combining Transgenes OV and PersonGens CAR-T therapies could overcome the challenges of solid tumor heterogeneity by improving the tumor microenvironment.

About Transgene
Transgene (Euronext: TNG) is a biotechnology company focused on designing and developing targeted immunotherapies for the treatment of cancer. Transgenes programs utilize viral vector technology with the goal of indirectly or directly killing cancer cells.
The Companys clinical-stage programs consist of two therapeutic vaccines (TG4001 for the treatment of HPV-positive cancers, and TG4050, the first individualized therapeutic vaccine based on the myvac® platform) as well as two oncolytic viruses (TG6002 for the treatment of solid tumors, and BT-001, the first oncolytic virus based on the Invir.IO platform).
With Transgenes 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. Transgene has an ongoing Invir.IO collaboration with AstraZeneca.

About PersonGen
PersonGens vision and goal are to develop high-quality cellular therapeutics that cancer patients really need. Founded in 2010, PersonGen has turned into a state-level high-tech enterprise focusing on R&D of breakthrough and innovative cellular immunotherapy technology and drug products for cancers. The company is dedicated to developing first-in-class and best-in-class CAR-T cell drugs. The Headquarter and the R&D Center (PersonGen -Suzhou is located in SIP, Suzhou, Jiangsu Province; the Industrial Cell Manufacturing Center (PersonGen-Anke) is located in Hefei, Anhui Province; and a newly formed Center for Cell Preparation and Supply is located in Shijiazhuang, Hebai Province, which aims to have northern part of China covered under its service supply-chain.
Since its inception, the company has continuously gained the favor of investors. In 2012, PersonGen received angel round investment from Suzhou Industrial Park (SIP) Leading Venture Capital, Suzhou Industrial Park Venture Capital Guide Fund and other partners. In 2015 and 2016, it received strategic investment from Anhui Anke Biotechnology (Group) Co.,Ltd.. At the beginning of 2021, PersonGen (Suzhou) and PersonGen-Anke completed a major internal restructuring and followed by A round of investment of nearly 100 million yuan from YuanBio Venture Capital, Puenguoxin Equity Investment and Sangel Capital. At the end of 2021, the restructured PersonGen attracted B round financing of over 200 million yuan co-led by CCIC and Huatai Securities, and co-invested by Panyi Capital and Huatong Capital. This B round investment provides a greater impetus for the further development of PersonGen.
With its first-class R&D capabilities on cell therapy drugs, its automatic CAR-T cell preparation pipeline, and advanced lentiviral vector industrial process system, PersonGen has successfully developed several first-in-class and best-in-class therapeutic cell products, covering most hematological tumors and some solid tumors. Among them, first-in-class PA3-17 injection for T-lymphoblastic leukemia/lymphoma is the first autologous CD7-CAR-T cell drug candidate in the world that was approved for registered clinical trials, and it was designated as an orphan drug by the US FDA; the TAA06 CAR-T cell injection, developed for treating solid tumors in children and adults, has demonstrated outstanding tumor clearance efficacy in preclinical studies, and is now entering into the IND application phase in China.
