STRASBOURG, France--(BUSINESS WIRE)--#HBV--Regulatory News:

Transgene (Euronext Paris: TNG) (Paris:TNG), a biotech company that designs and develops virus-based immunotherapies for the treatment of cancer, today publishes its financial results for 2022 and provides an update on its product pipeline.

Hedi Ben Brahim, CEO of Transgene, commented: I am extremely happy with the multiple positive milestones that Transgene has delivered in 2022 and I would like to thank all our employees and partners for their commitment and support. We also are very encouraged by the growing industry interest in therapeutic cancer vaccines and oncolytic viruses that have the potential to become new standards of care for the treatment of solid tumors. This trend backs us in our strategy and validates our technological and medical choices. I am confident that Transgene is at the forefront of helping to realize the potential of these exciting treatment modalities.

“With regard to our therapeutic cancer vaccine pipeline, we presented new Phase I results for TG4050 demonstrating the full clinical and commercial potential of this highly innovative neoantigen vaccine in patients with head and neck cancer. These very encouraging data have led us to start the planning of Phase II trial. Positive data from this Phase II trial could be used for a potential registration of TG4050. For TG4001, our most advanced product, the positive outcome of the interim analysis of the Phase II trial in HPV-positive cancers has allowed us to reduce the total number of patients to be randomized in the ongoing study.

“Turning to the oncolytic virus platform, we have achieved two important milestones. We presented new positive data from the Phase I trial evaluating our oncolytic virus TG6002 administered intravenously, showing in all patients its ability to reach the tumor, multiply and express its payload. The ability to administer our oncolytic viruses intravenously significantly expands the range of solid tumors they can be used to treat and the market opportunity they can access. In addition, we announced the launch of a new oncolytic virus, TG6050. This multi-armed oncolytic virus has been designed to address major solid tumor indications, such as lung cancer, and will begin a Phase I in the months ahead.

“The progress we have made in 2022 has positioned Transgene to deliver multiple major milestones in the next 18 months, including launching potentially registrational trials for our two most advanced therapeutic vaccine candidates, as well as a Phase I study with our high-potential oncolytic virus, TG6050, given by intravenous administration.

“Based on the potential of TG4050, TG4001 and TG6050, I believe that Transgene has a very exciting future and is well positioned to deliver for all of its key stakeholders.

Key achievements in 2022 and expected near-term news flow

Therapeutic Cancer Vaccines

TG4001: Positive result from interim analysis of randomized Phase II trial in HPV-positive anogenital cancers

With TG4001, Transgene aims to bring a new solution to patients with HPV-positive anogenital cancers who currently have very limited second-line treatment options.

In November 2022, Transgene announced that following a prespecified interim analysis of its randomized, Phase II clinical study comparing TG4001 in combination with avelumab vs avelumab alone in patients with HPV16-positive anogenital tumors (NCT: 03260023), the Independent Data Monitoring Committee (IDMC) has recommended the study continue. Based on progression-free survival (PFS) and positive efficacy signals observed in the interim analysis, the trial is now expected to enroll a total of 120 patients compared to the initial forecast of 150 patients.

Transgene anticipates the last patient to be randomized in the trial in the first half of 2024, and final results to be communicated in 2024.

Based on the positive outcome of the interim analysis, we are already working on the initial design of a potentially registrational trial to further confirm the benefit of this therapeutic vaccine.

TG4050: Strong clinical and commercial potential confirmed by initial data from the two ongoing Phase I trials – Transgene is preparing a Phase II trial in head and neck cancers

The personalized therapeutic vaccine TG4050 is intended to extend the remission of patients at high risk of relapse.

In the randomized Phase I trial in head and neck patients, following surgery and radio-chemotherapy, the latest data reported was as of the end of August 2022, when 20 of the 30 planned patients had been randomized.

All 10 evaluable patients who were vaccinated with TG4050 remained stable and in complete response at the cutoff date. This contrasts with the control group where 2 out of the 10 patients, who did not receive the vaccine, have relapsed. Transgene expects treatment start of the last patient in this Phase I trial in the first half of 2023.

In the current Phase I ovarian cancer trial (n=5), one patient treated after an elevation of CA-125 experienced a normalization of CA-125 without clinical progression for nine months until death from an unrelated chronic illness. Another patient was treated upon onset of radiological evidence of relapse and remained stable for 11.4 months. Although enrollment in this trial has been completed, treatment of patients is significantly delayed by the recent registration of PARP inhibitors, extending the time to relapse, which is required before they can receive treatment with TG4050.

Transgene has also produced data on circulating tumor DNA (ctDNA); signals of this increasingly validated surrogate marker of efficacy are particularly encouraging. Combined with the first signs of clinical activity, these results suggest that the individualized TG4050 vaccine has the potential to extend the period of remission, potentially offering a new treatment option for cancer patients.

In the two clinical studies, enrollment has been completed. To date, TG4050 vaccine has been well tolerated and no related Serious Adverse Events have been reported.

The Company is preparing a Phase II trial in head and neck cancers. Positive data from this upcoming trial could be used for a potential registration of TG4050.

Further information on our development plans for TG4050 will be communicated following the presentation of a poster at the American Association for Cancer Research (AACR) Annual Meeting (April 2023).

Oncolytic Viruses

TG6002: New data support the potential of intravenous administration of Invir.IO®-based oncolytic viruses Key competitive advantage

Clinical data generated with TG6002, has enabled Transgene to confirm the mechanism of action, competitive advantages and safety of our Invir.IO® based oncolytic viruses.

Data generated on 37 patients treated in the Phase I study assessing its intravenous administration (IV) have been presented at the European Society for Medical Oncology (ESMO) Annual Congress (September 2022).

These findings support the potential of IV administration of Invir.IO®-based oncolytic viruses, extending the use of these therapies to a much broader range of solid tumors. At present the use of oncolytic viruses is limited by their intratumoral administration.

Additional data will be produced from the Phase I program and will be presented at AACR (April 2023).

BT-001: Positive initial clinical data in monotherapy

In June 2022, Transgene and BioInvent released positive progress and safety data in the ongoing Phase I/IIa trial evaluating BT-001 in patients with solid tumors. The initial data generated in the Part A of the Phase I trial demonstrated that BT-001 alone is well tolerated, with first signs of anti-tumor activity in a hard-to-treat population and confirmed the mechanism of action of BT-001 as a single agent.

A clinical collaboration and supply agreement for KEYTRUDA® (pembrolizumab) was signed with MSD (Merck & Co) at the end of June 2022. The Part B of the Phase I trial (in combination with pembrolizumab) is expected to start in the second half of 2023.

TG6050: Novel Invir.IO® candidate designed to express IL-12 and be administered IV to enter the clinic

In early 2023, Transgene announced the regulatory approval to initiate a clinical trial of TG6050, a novel oncolytic virus from its Invir.IO® platform. This innovative candidate has been designed to express human IL-12, a cytokine known to trigger a potent anti-tumor immune response, and a full-length anti-CTLA4 antibody.

The Delivir trial will evaluate TG6050 in patients with advanced non-small cell lung cancer who have failed treatment with an anti-PD1 agent.

The first patient will be enrolled in the first half of 2023. With TG6050, Transgene seeks to capitalize on the attractiveness of IL-12, while limiting exposure to its systemic toxicity through the selectivity of Invir.IO® oncolytic viruses.

Collaboration with AstraZeneca

The research collaboration with AstraZeneca on viruses derived from the Invir.IO® platform continues to move forward.

Key scientific advisors

In March 2023, Transgene appointed Dr. John C. Bell and Dr. Pedro Romero as key scientific advisors. These key opinion leaders in cancer immunotherapy bring considerable expertise to Transgene.

Appendix B: Management Discussion of 2022 Financials

Operating income

Income from collaboration and licensing agreements represented €3.1 million in 2022 versus €10.0 million in 2021. The income consisted primarily of research and development services recognized from the collaboration with AstraZeneca over the period amounting to €3.1 million in 2022 (versus €9.9 million in 2021). This difference is mainly due to the first license option exercised by AstraZeneca in 2021 for €7.1 million, for an oncolytic virus developed by Transgene.

Public funding for research expenses accounted for €6.9 million in 2022 (versus €7.0 million in 2021), mainly due to research tax credit.

Other income

Other income amounted to €0.3 million in 2022 versus €0.4 million in 2021. This consisted for €0.2 million of the NEOVIVA repayable advances at a preferred rate in 2022, as in 2021.
