BioNTech to Present Clinical and Preclinical Data Updates Across Multiple Immuno-Oncology Programs at 2023 SITC Annual Meeting

31 October 2023

MAINZ, Germany, October 31, 2023 BioNTech SE (Nasdaq: BNTX, “BioNTech” or “the Company”) will present data updates across multiple immuno-oncology programs at the Society for Immunotherapy of Cancer’s (“SITC”) 38th Annual Meeting in San Diego, USA, from November 1-5, 2023. The updates will feature one oral and four poster presentations for the investigational anti-CTLA-4 monoclonal antibody candidate BNT316/ONC-392 (gotistobart), the FixVac off-the-shelf mRNA cancer vaccine BNT116, the ex-vivo T cell therapy BNT221, and the two bi-specific antibodies BNT312/GEN1042 and BNT313/GEN1053.

Highlights of BioNTech’s clinical stage programs to be presented at SITC Annual Meeting 2023:

  • BioNTech will share new Phase 1/2 (NCT04140526) data of its next-generation anti-CTLA-4 monoclonal antibody candidate BNT316/ONC-392 (gotistobart) in non-small cell lung cancer (“NSCLC”) patients that progressed on anti-PD-1/PD-L1 therapy. The candidate is being jointly developed with OncoC4, Inc. (“OncoC4”). The results show encouraging anti-tumor activity for BNT316/ONC-392 as monotherapy in patients with immuno-oncologic (IO)-resistant NSCLC, as well as a manageable safety profile.
  • First clinical data will be presented on the LuCa-MERIT-1 Phase 1 study (NCT05142189) with BioNTech’s off-the-shelf mRNA therapeutic cancer vaccine candidate BNT116 alone and in combination with cemiplimab in patients with advanced, unresectable, or metastatic NSCLC. The data show encouraging initial clinical activity in heavily pre-treated patients with advanced NSCLC and a tolerable safety profile.
  • As a follow-up to the data recently presented at ESMO, BioNTech will give an update on the first-in-human Phase 1 study with BNT221 (NCT04625205), a personalized, autologous neoantigen-specific T cell therapy, which is being evaluated in patients with anti-PD-1- and anti-CTLA-4-pretreated advanced or metastatic melanoma. The data update includes nine patients. Seven of these patients have stable disease with shrinkage of tumor lesions in four of these patients. The initial results show a manageable safety profile with no dose limiting toxicities. In addition, preliminary translational data show multiple functional neoantigen-specific T cell responses in all evaluable patients.

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.
