BioNTech to Showcase Advances in Cancer Therapy at ESMO Congress 2023

(IN BRIEF) BioNTech will be presenting updates on multiple programs across its oncology pipeline at the European Society for Molecular Oncology (ESMO) Congress 2023. These updates include data on investigational CAR-T and ex-vivo T cell therapies, a novel ADC (antibody-drug conjugate), a FixVac off-the-shelf mRNA cancer vaccine, and a bi-specific antibody. Key highlights include data on BioNTech’s autologous CAR-T therapy BNT211, first-in-human data on the next-generation Trop-2 targeting ADC candidate BNT325, and updates on mRNA-based immunotherapies.

(PRESS RELEASE) MAINZ, 17-Oct-2023 — /EuropaWire/ — BioNTech SE (Nasdaq: BNTX, “BioNTech” or “the Company”) will present data across its oncology pipeline, covering multiple solid tumor types and novel mechanisms of action, at the European Society for Molecular Oncology (“ESMO”) Congress 2023 in Madrid, Spain from October 20-24, 2023. The updates will feature oral and poster presentations for five candidates of BioNTech’s clinical pipeline across the Company’s drug classes, which comprise mRNA-based immunotherapies, cell therapies, protein-based therapeutics, and small molecules.

“This year’s ESMO presentations underline the potential of BioNTech’s precision medicine toolkit for the treatment of solid tumor indications with high unmet medical need, where many patients still remain underserved,” said Prof. Özlem Türeci, M.D., Co-Founder and Chief Medical Officer at BioNTech. “We aim to develop and combine innovative immunotherapies for patients at different disease stages, which we believe could increase the likelihood of therapeutic success, reduce the risk of emergence of secondary resistance mechanisms, and unlock a larger potential patient population.”

Highlights of BioNTech’s clinical stage programs to be presented at ESMO Congress 2023:

Cell therapies

• BioNTech will present new data of its investigational autologous Claudin-6 (CLDN6)-directed CAR-T cell therapy BNT211 (NCT04503278), including data showing the potential of combining these CAR-T cells with a CLDN6-encoding CAR-T cell amplifying mRNA vaccine (“CARVac”).
• Initial data from BioNTech’s first-in-human Phase 1 study with BNT221 (NCT04625205), a personalized, autologous neoantigen-specific T cell therapy, will be presented. The initial results show a manageable safety profile and tumor regression in several patients with anti-PD-1 and anti-CTLA4 pretreated advanced or metastatic melanoma.

Protein-based therapeutics

• The Company will present first-in-human data of BNT325 (DB-1305) (NCT05438329), a next-generation Trop-2-targeting antibody-drug conjugate (“ADC”), which is being jointly developed with Duality Biologics. Initial data with this candidate show encouraging preliminary efficacy and a manageable safety profile in patients with advanced/metastatic non-small cell lung cancer (NSCLC).

mRNA-based immunotherapies

• A trial in progress poster will inform on the ongoing EMPOWERVAX Lung 1 Phase 2 trial (NCT05557591), which is being conducted together with Regeneron, evaluating the efficacy and safety of BioNTech’s fully-owned off-the-shelf mRNA cancer vaccine candidate BNT116 in combination with cemiplimab versus cemiplimab alone in the first-line treatment of patients with advanced NSCLC and PD-L1 expression ≥50%.

In addition, BioNTech will also present pre-clinical data from its BNT314 (GEN1059) program, which is being jointly developed with Genmab. BNT314 (GEN1059) is a novel bispecific antibody candidate aimed at boosting antitumor immune responses through EpCAM-dependent 4-1BB agonistic activity. In pre-clinical studies, BNT314 (GEN1059) enhanced T-cell activation, proliferation, and effector functions in vitro and ex vivo and promoted antitumor activity in vivo. A Phase 1/2 trial is planned to start by early 2024 and will assess the safety and preliminary antitumor activity of BNT314 (GEN1059) in patients with advanced or metastatic solid tumors.

BioNTech has established a diversified clinical oncology pipeline of more than 25 programs in high unmet medical need solid tumor indications in more than 30 clinical studies, including seven programs in advanced Phase 2 studies and one candidate in a pivotal Phase 3 study. BioNTech is advancing the Company’s key programs into late-stage development while strengthening its clinical-stage oncology pipeline with synergistic potential, with the aim to deliver the next generation of oncology breakthroughs.
