MAINZ, Germany, May 27, 2025 -- BioNTech SE (Nasdaq: BNTX, “BioNTech” or “the Company”) will present clinical trial data from select pipeline candidates across the Company’s diversified oncology portfolio at the American Society of Clinical Oncology (“ASCO”) Annual Meeting, to be held in Chicago, IL, from May 30 to June 3, 2025. The data highlight continued progress of the Company’s clinical programs consisting of complementary therapeutic modalities, including mRNA cancer immunotherapies, next-generation immunomodulators, and targeted therapies, including antibody-drug conjugates (“ADCs”). “We believe that the next era of cancer medicine will be defined by the interplay of complementary mechanisms and innovative molecules, unlocking their full potential through synergy. Our data presentations at this year's ASCO Annual Meeting show how we aim to help shape this era,” said Prof. Özlem Türeci, M.D., Co-Founder and Chief Medical Officer at BioNTech. “We will present clinical progress with two of our therapeutic modalities: our next generation immunomodulators, most notably our investigational anti-PD-L1xVEGF-A antibody BNT327, and for one of our ADC programs, which are an important pillar of our combination strategy. These data underline the potential of our assets to improve outcomes for patients.” Highlights of BioNTech’s oncology programs to be presented at ASCO 2025: Three presentations on BNT3271, an investigational anti-PD-L1xVEGF-A antibody, will detail data from ongoing later-stage and potentially registrational clinical trials: An oral presentation will feature the first data from a Phase 2 clinical trial (NCT05918107) of BNT327 in combination with chemotherapy as first-line treatment for patients with unresectable malignant mesothelioma. Malignant mesothelioma is a type of cancer that develops in the tissue that covers the lung or the abdomen. The preliminary data indicated anti-tumor activity and a manageable safety profile. Two posters will detail the ongoing global Phase 3 and Phase 2/3 clinical trials, ROSETTA Lung-01 (NCT06712355) in extensive-stage small cell lung cancer (“ES-SCLC”) and ROSETTA Lung-02 (NCT06712316) in non-small cell lung cancer (“NSCLC”). BNT327 combines the two complementary anti-tumor mechanisms of PD-L1 checkpoint and VEGF-A signaling blockade in the tumor microenvironment, thereby aiming to enhance anti-tumor activity. Data on BNT324/DB-1311, a B7H3-targeted ADC candidate, from an ongoing Phase 1/2 clinical trial (NCT05914116) in patients with heavily pre-treated castration-resistant prostate cancer (“CRPC”) will be presented during an oral session. The data indicated early clinical activity and a manageable safety profile. BNT324/DB-1311 received Fast Track Designation by the U.S. Food & Drug Administration (“FDA”) for this patient population in 2024 and is being developed in collaboration with Duality Biologics (Suzhou) Co. Ltd. (“DualityBio”). Preliminary data on BNT316/ONC-392 (gotistobart), an investigational anti-CTLA-4 antibody, from two ongoing Phase 1/2 clinical trials evaluating the antibody candidate in combination with current standard of care treatments will be presented. Data from the PRESERVE-001 clinical trial (NCT04140526) in patients with advanced melanoma indicated a manageable safety profile and early signs of anti-tumor activity. The data included an analysis of overall survival (“OS”) and an ad-hoc analysis of next-treatment free survival (“NTFS”), a measure for potential long-lasting benefit after initial treatment. Data from the PRESERVE-006 clinical trial (NCT05682443) in patients with metastatic CRPC indicated a manageable safety profile and preliminary efficacy. BNT316/ONC-392 is being developed in collaboration with OncoC4, Inc. (“OncoC4”).Data on BNT142 from an exploratory Phase 1/2 dose finding trial (NCT05262530) in patients with CLDN6-positive advanced solid tumors will be featured in an oral presentation. BNT142 is an investigational lipid nanoparticle-formulated mRNA immunotherapy that encodes a CD3xCDLN6 T cell engager antibody. Preliminary data indicated a manageable safety profile and early signs of clinical activity, supporting scientific proof-of-concept and underscoring the potential of mRNA-encoded bispecific antibodies. BioNTech has established a diversified oncology portfolio to develop novel treatment approaches for patients living with cancer. The Company is advancing its oncology pipeline across multiple solid tumor indications, including more than 20 active Phase 2 and 3 clinical trials with a strategic focus on two pan-tumor priority programs: investigational mRNA cancer immunotherapies and the next-generation immunomodulator candidate BNT327. BioNTech expects multiple data readouts in 2025 and 2026 aimed at supporting its strategy and advancing the Company towards becoming a diversified multi-product oncology company.

DSP107 in combination with atezolizumab in 3rd line microsatellite stable colorectal cancer (MSS-CRC) patients elicits anti-tumor activity and extends survival including in patients with liver metastases MODI'IN, Israel, May 27, 2025 /PRNewswire/ -- KAHR, a clinical-stage biotech company developing DSP107, a first-in-class bi-specific 4-1BB T-cell engager that activates innate and adaptive immunity to treat solid tumors, today announced that positive results from the Phase 2 dose expansion cohort of DSP107 in combination with atezolizumab (Tecentriq®), an anti-PD-L1 cancer immunotherapy, in patients with 3rd line microsatellite stable metastatic colorectal cancer (MSS-CRC) will be presented in an oral presentation at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting. The meeting will be held May 30 - June 3, 2025, in Chicago, Illinois and virtually. In addition to its favorable safety profile, the combination has shown anti-tumor activity and extended survival including in patients with liver metastases. "We are happy with the opportunity to present data from the Phase 2 dose expansion cohort of DSP107 in combination with a PD1/PD-L1 checkpoint inhibitor in an oral presentation at ASCO's Annual Meeting," said Yaron Pereg, Ph.D., Chief Executive Officer of KAHR. "This recognition is evidence for the significant potential of this immunotherapy combination to benefit the treatment of MSS-CRC patients including those with active liver metastases, a devastating disease representing an unmet medical need. We look forward to sharing next week the exciting, updated, overall survival data for this combination, which has continued to improve in 2025 beyond the data published in the abstract." Details for the oral presentation are as follows: Presentation information: Title: Phase 2 dose expansion study of DSP107, a first-in-class bi-specific 4-1BB T-cell engager, with and without atezolizumab in metastatic MSS colorectal cancer patients. Session Title: Gastrointestinal Cancer—Colorectal and Anal Session Date: 6/1/2025 Session Time: 11:30 AM-1:00 PM CDT Presenter: Anwaar Saeed, MD, Associate Professor of Medicine, University of Pittsburgh Medical Center and Director, Gastrointestinal Disease Center, UPMC Hillman Cancer Center Abstract Number for Publication: 3517 Abstract available on the ASCO website About the Phase 2 dose expansion cohort of DSP107 in combination with atezolizumab for MSS-CRC The MSS-CRC dose expansion phase of the study was an open label, multi-center trial (NCT04440735) that enrolled patients with 3rd line MSS colorectal cancer patients, treated weekly with 10 mg/kg DSP107 infusions and atezolizumab (1200 mg) every three weeks, until disease progression. The primary objective was to determine the safety and tolerability of DSP107 in combination with atezolizumab. The secondary objective was to assess the preliminary efficacy of DSP107 in combination with atezolizumab. About DSP107 KAHR's lead drug candidate, DSP107, is a first-in-class bi-specific 4-1BB T-cell engager utilizing CD47 overexpression as a tumor anchor. DSP107 binds to CD47 that cancer cells express on their cell surface. Once bound, DSP107 converts the CD47 signal, which cancer uses to camouflage itself from the innate immune system, into a 4-1BB signal, which attracts and activates adaptive immune cells, primarily cancer cytotoxic CD8 T-cells. In this way, DSP107 engages both parts of the immune system in a wholistic anti-cancer response. This is particularly relevant in colorectal cancer, where 70%+ of the metastatic patients have metastases in the liver, and where liver metastases highly express CD47 in response to first- and second-line chemotherapy treatments. Previous attempts to treat colorectal cancer with immunotherapy have failed as there is a lack of immune cells in the tumor. DSP107 is unique in that it takes advantage of CD47 expression to drive immune cells into the tumor. DSP107 is also being tested in Phase 2 expansion cohort in 2L/3L PD1-experienced NSCLC. About microsatellite stable metastatic colorectal cancer (MSS-CRC) Microsatellite stable metastatic colorectal cancer (MSS-CRC) is a subtype of colorectal cancer that lacks deficiencies in the DNA mismatch repair system, resulting in stable microsatellite regions within the genome. Unlike microsatellite instability-high (MSI-H) tumors, MSS-CRC exhibits lower tumor mutational burden and is less responsive to immunotherapy. MSS tumors represent the majority of colorectal cancer cases and are typically more challenging to treat. Standard treatment for metastatic MSS-CRC often involves a combination of chemotherapy, targeted therapy, and in select cases, surgical intervention. About KAHR KAHR develops novel, dual-targeting fusion protein therapeutics engineered to activate both the innate and adaptive immune systems simultaneously and localize that response in the tumor microenvironment. The Company is developing multifunctional fusion proteins that boost the immune systems' response to cancer. KAHR Bio was founded based on technology developed at the University of Pennsylvania and Thomas Jefferson University. For more information, please visit kahrbio.com/.
