MAINZ, Germany, May 21, 2024 – BioNTech SE (Nasdaq: BNTX, “BioNTech” or “the Company”) will present clinical trial data for selected programs from the Company’s diversified immuno-oncology pipeline at the American Society of Clinical Oncology (“ASCO”) Annual Meeting in Chicago, Illinois, from May 31 to June 4, 2024. Moreover, in support of the Company’s ongoing CAR-T cell and individualized mRNA programs, BioNTech will also present epidemiological and real-world data from two observational studies in patient populations for which product candidates are being developed in the Company’s respective clinical programs.

“Our aim is to develop innovative treatment options across the continuum of cancer disease and establish new treatment paradigms that have the potential to address the fundamental challenges of treating cancer to drive meaningful improvements in the long-term survival rates for patients,” said Prof. Özlem Türeci, M.D., Co-Founder and Chief Medical Officer at BioNTech. “The data from the interventional and observational studies that we will present at this year’s ASCO are of relevance for progress towards our goal as they will contribute to informing the direction of further development of several of our priority product candidates as well as the design of planned pivotal and later-stage clinical trials across all three key pillars of our diversified oncology pipeline, including novel immunomodulators, targeted therapies such as cell therapies and ADCs, and mRNA-based therapeutic cancer vaccines.”

Highlights of BioNTech’s updates to be presented at the ASCO Annual Meeting 2024:

• Updates on several Phase 1b/2a trials investigating BNT327/PM8002 as a monotherapy in patients with solid tumors will be presented. BNT327/PM8002 is a bispecific antibody candidate combining PD-L1 checkpoint inhibition with VEGF-A neutralization to create a cycle of vascular normalization and immunostimulation in the microenvironment of the tumor. Two posters will provide clinical data updates for cohorts with advanced cervical cancer, platinum-resistant recurrent ovarian cancer and advanced non-small cell lung cancer (“NSCLC”). The product candidate is being developed in collaboration with Biotheus Inc. (“Biotheus”).
  
  
• Initial results from the randomized, open-label, Phase 2 trial (NCT05117242) with the bispecific antibody candidate BNT311/GEN1046 (acasunlimab) alone or in combination with pembrolizumab in patients with previously treated metastatic NSCLC (“mNSCLC”) will be presented. BNT311/GEN1046 combines PD-L1 checkpoint inhibition with 4-1BB costimulatory activation. The product candidate is being developed in collaboration with Genmab S/A (“Genmab”).
  
  
• BioNTech will present preliminary data of an epidemiological study (NCT04813627) that correlates post-operative circulating tumor DNA (“ctDNA”), a cancer biomarker for minimal residual disease, with disease-free survival in patients with colorectal cancer (“CRC”). This observational study provides supportive epidemiological and prognostic data for the ongoing interventional Phase 2 trial (NCT04486378) with the individualized neoantigen-specific immunotherapy (“iNeST”) candidate autogene cevumeran (BNT122, RO7198457) in ctDNA-positive, high-risk stage II/stage III adjuvant CRC. Autogene cevumeran is jointly being developed by BioNTech and Genentech Inc. (“Genentech”), a member of the Roche Group.
  
  
• BioNTech will present an analysis of real-world data that investigated the overall survival, treatment patterns and prognostic variables of patients with testicular germ cell tumors receiving palliative chemotherapy. This analysis will inform the design of BioNTech’s planned pivotal trial with the Company’s CAR-T cell therapy candidate BNT211 in patients with germ cell tumors. BNT211 combines an autologous CAR-T cell therapy candidate targeting the oncofetal antigen Claudin-6 (“CLDN6”) and an investigational CLDN6-encoding CAR-T cell amplifying RNA vaccine (“CARVac”).

BioNTech has established a diversified clinical oncology pipeline based on its modular multi-platform approach. The Company is advancing more than 20 clinical programs in unmet medical need solid tumor indications, including mRNA-based immunotherapies, targeted therapies entailing cell therapies and antibody-drug conjugates (ADCs), and novel immunomodulators. These candidates are currently being evaluated in more than 30 clinical studies, including nine programs in advanced Phase 2 trials and two candidates in pivotal Phase 3 trials. BioNTech is advancing key programs into late-stage development with the aim to have ten or more potentially registrational trials in its oncology pipeline by the end of 2024. The Company aims to launch its first cancer immunotherapy in 2026. By 2030, BioNTech plans to obtain approvals for a total of ten cancer indications across various drug classes.
