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

Transgene (Euronext Paris: TNG), a biotech company that designs and develops virus-based immunotherapies for the treatment of cancer, today publishes its financial results for the six-month period ended June 30, 2022 and provides an update on the progress of its portfolio of clinical-stage drug candidates.

“Our goal is to transform the outlook for cancer patients with solid tumors by developing immunotherapies that can become vital components of the therapeutic arsenal. To achieve this, Transgene has created two highly innovative technology platforms that have delivered multiple therapeutic vaccine and oncolytic drug candidates now being evaluated in clinical trials,” commented Hedi Ben Brahim, CEO of Transgene.
“We have made remarkable progress in the first half of 2022, with initial results in patients reinforcing my confidence that we are on track to progress through the clinic successfully. With several further important clinical milestones to be announced before the end of the year, we are approaching a critical moment to become a world leader in innovative cancer therapies.”

Highlights and expected news flow

TG4001 – Result of the Phase II interim analysis to be released in Q4 2022

Just over 50 patients have been enrolled in the randomized Phase II trial evaluating the combination of TG4001 and avelumab in HPV-induced anogenital cancers. Transgene expects to report the results of the interim analysis in Q4 2022.

The objective of this trial is to demonstrate the superiority of the combination of TG4001 + avelumab versus avelumab as a single agent to improve progression-free survival (primary endpoint of the trial) and, in the longer term, overall patient survival.

In this Q4 2022 communication, Transgene will specify, based on the results of the interim analysis, the total number of patients that must be included in the trial to confirm the efficacy of the therapy and achieve statistically significant progression-free survival improvement. Indeed, the design of the trial allows for the total number of patients to be adjusted according to the results obtained in the interim analysis and based on the recommendations of the IDMC (independent data monitoring committee).

TG4050 - Patients treated with our neoantigen vaccine show a robust, vaccine specific immune response

Transgene presented new positive preliminary data from TG4050, its proprietary cancer vaccine based on the myvac® platform, at the AACR (April 2022) and ASCO (June 2022) meetings. These data show good safety and robust immunogenicity. The induction of immune responses is particularly efficient (100% of patients evaluated at the data cut-off date showed a specific cellular response) and is associated with disease regression.

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.

Additional data from the two ongoing Phase I trials (ovarian cancer and head and neck cancers) are expected in the second half of 2022. The information generated will be key to designing the Phase II trial of TG4050, which could start as early as 2023.

In addition, Transgene has completed patient inclusion in the two Phase I trials. These patients are now being monitored until they become eligible for treatment per study protocol.

An article on Transgene’s personalized vaccine technology was published in the Journal for ImmunoTherapy of Canceri. The publication demonstrated that Transgene successfully developed a patient specific vaccine within a few weeks for a study case patient with a low tumor mutational burden (TMB).

TG6002 – Phase I trials completed – Confirms the strong potential of IV administration of the Invir.IO™ oncolytic viruses

Patient enrollment has been completed in the Phase I trial evaluating the intravenous (IV) route of administration: 51 patients received TG6002 at different doses and with different schedules.

This route of administration has considerable therapeutic and market potential as it allows targeting many types of internal lesions and metastases inaccessible by intratumoral injection (injection of the oncolytic virus directly into the tumor) which is currently the only approved route of administration for an oncolytic virus.

New data from this trial will be presented in a poster at the ESMO Congress on September 11, 2022 at 12:00 pm CET. The data confirm the safety and feasibility of the IV route for TG6002 and support the potential of IV administration of Invir.IO™-based oncolytic viruses, extending the use of these therapies to a broad range of solid tumors.

In the TG6002 Phase I trial evaluating the intrahepatic artery route of administration (IHA), enrollment has been completed. Data are currently being analyzed and will be presented at a conference in the first half of 2023.

BT-001 – Good safety and first signs of antitumor activity as a monotherapy

Transgene and BioInvent provided an update on the progress of the clinical trial of BT-001, an oncolytic Vaccinia virus encoding an anti-CTLA-4 antibody and GM-CSF, in June 2022. Initial data from Part A of the Phase I trial demonstrated that BT-001 as a single-agent is well tolerated, with first signs of anti-tumor activity observed in a hard-to-treat patient population. The mechanism of action for BT-001, as a single agent, was also confirmed: the virus replicates in the tumor and the anti-CTLA-4 antibody is expressed in the tumor.

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

Promising preclinical data with BT-001 were presented at AACR 2022 and published in the Journal for ImmunoTherapy of Cancerii demonstrating the broad and robust antitumor activity of this Invir.IO™ oncolytic virus.

Change in governance and appointment within the executive committee

Transgene reinforced its corporate governance by separating the roles of Chairman and CEO. Dr. Alessandro Riva, MD, became Non-Executive Chairman of the Company (May 25, 2022). With 30 years’ experience in the Life Sciences industry, Dr. Riva is closely working with Transgene’s CEO Hedi Ben Brahim to realize the potential of the Company’s technology platforms and products to benefit cancer patients.

Prof. Jean‑Yves Blay, MD, PhD, and Laurence Espinasse were appointed as members of the board of directors.

Steven Bloom joined Transgene as Vice President, Chief Business Officer (CBO). In this position, he has become a member of the executive committee, leading global business development strategy, alliance management and program management. In particular, he is focused on building the profile of Transgene in the USA, where he is based, as part of establishing the Company as a world leader in virus-based immunotherapies.
