Key events and upcoming milestones

Over the first quarter of 2025, all of Transgene’s preclinical and clinical assets progressed in line with expectations.

Individualized neoantigen therapeutic cancer vaccine (TG4050)

Transgene will deliver a rapid oral presentation on TG4050, its lead individualized neoantigen therapeutic cancer vaccine based on its myvac platform and powered by NEC’s AI technologies, at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) 2025 annual meeting in Chicago (USA).

This oral presentation, which will take place on June 1, 2025, is part of a session that highlights clinical data that stood out among many submissions.

The updated data will include disease-free survival (DFS) data at 24-month follow-up for all patients in the Phase I part of the trial evaluating TG4050 as adjuvant treatment for head and neck cancer.

As the treatment landscape evolves, these updated clinical data in the adjuvant treatment of operable head and neck cancer will be instrumental in determining TG4050’s optimal development path towards registration in this indication.

In the Phase II part of the trial, patient enrollment continues to progress at a good pace and randomization is expected to be completed on schedule in Q4 2025.

The myvac individualized cancer vaccine platform can be applied across a range of solid tumors where in many cases a significant unmet medical need remains. Consequently, Transgene is starting initial preparations for a new Phase I trial in a second undisclosed indication in an early treatment setting, with the aim to initiate the trial in Q4 2025.

TG4001

The Company will present a poster on clinical data from the randomized Phase II trial of TG4001 in combination with avelumab in HPV16-positive recurrent/metastatic anogenital and cervical cancer at ASCO (Free ASCO Whitepaper). While the primary endpoint of the Phase II study was not met, positive signals in the cervical cancer subgroup have been observed and further details will be included in the poster presentation.

The abstracts will be available on the ASCO (Free ASCO Whitepaper) website on May 22, 2025, at 5 p.m. ET.

Governance

Dr. Simone Steiner joined Transgene as Chief Technical Officer (CTO) on April 1, 2025. She is responsible for manufacturing and process development for Transgene’s innovative immunotherapy product pipeline and leads the optimization of the manufacturing process for individualized neoantigen therapeutic vaccines. She is also involved in the development of potential new candidates based on the myvac platform, as well as in planning potential future clinical studies.

Dr. Steiner reports to Chairman and CEO, Alessandro Riva, and is a member of the Executive Committee.

During the first quarter of 2025, operating revenue mostly comprised Research Tax Credit of 2.3 million compared to €1.6 million for the same period in 2024. This increase reflects the progress of the ongoing Phase II part of the clinical trial evaluating TG4050 in head and neck cancer.

Cash, cash equivalents and other financial assets

Cash, cash equivalents and other financial assets stood at €15.6 million as of March 31, 2025, compared to €16.7 million as of December 31, 2024. In the first quarter of 2025, Transgene’s net cash burn was €14.8 million compared to €11.2 million for the same period in 2024. This results from progress in the Phase II part of the trial evaluating TG4050 in head and neck cancer, with sustained patient enrollment and related expenses, including the manufacturing of individualized batches.

In March 2025, the Company signed a new amendment to the current account advance agreement with TSGH (Institut Mérieux), which increases the total amount of the facility by €15 million to €48 million. The Company has drawn down €22.5 million from this facility as of March 31, 2025.

With this credit facility and the support of TSGH (Institut Mérieux), Transgene is now able to fund its business until the end of April 2026, enabling the Company to reach important development milestones and deliver significant news flow on its portfolio.
