On April 24, 2025 BioNTech SE (Nasdaq: BNTX, "BioNTech" or "the Company") reported it will present data for selected assets from its diversified oncology pipeline, including mRNA cancer immunotherapies, next-generation immunomodulators, and targeted therapies, at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) ("AACR") Annual Meeting held in Chicago, Illinois from April 25-30, 2025 (Press release, BioNTech, APR 24, 2025, View Source [SID1234652098]). The oral and poster presentations underline both the progress of BioNTech’s advanced priority oncology programs as well as the execution of the Company’s combination strategy in oncology, with first data to be presented for the combination of the PD-L1xVEGF-A bispecific antibody candidate BNT3271 plus antibody-drug conjugates ("ADCs").

"We believe that the future standard of care for the treatment of advanced cancers will be combinations with novel immuno-oncology backbones," said Prof. Özlem Türeci, M.D., Co-Founder and Chief Medical Officer at BioNTech. "Our data presentations at this year’s AACR (Free AACR Whitepaper) support our approach to combine complementary mechanisms of action with the aim of driving synergistic anti-tumor activity. The data we present indicate that we are well positioned to work towards our vision of improving outcomes for patients across the full continuum of cancer disease."

Highlights of BioNTech’s oncology programs to be presented at AACR (Free AACR Whitepaper) 2025:

BioNTech will present preclinical data characterizing the mode of action of BNT327. BNT327 is an investigational next-generation bispecific antibody combining PD-L1 checkpoint inhibition with VEGF-A neutralization. BNT327 showed a high binding affinity to PD-L1 and VEGF-A and efficient blocking of PD-1/PD-L1 and VEGF-A/VEGFR2 signaling. Anti-tumor activity superior to single PD-1/PD-L1 blockade or anti-VEGF-A treatment was observed in multiple tumor models.

First data for the combination of BNT327 with various ADC candidates, which are being jointly developed by BioNTech and Duality Biologics (Suzhou) Co. Ltd. ("DualityBio"), will be presented. The presentation will include preclinical evaluation of BNT327 plus ADCs, showing inhibition of tumor growth that is superior to each candidate alone. Further, early clinical data of the ongoing global Phase 1/2 trial (NCT05438329) of BNT327 in combination with BNT325/DB-1305, a TROP2-targeting ADC candidate, including safety and early efficacy data, will be presented in the poster session.

BioNTech will present data from the Phase 1 clinical trial LuCa-MERIT-1 (NCT05142189) for its mRNA cancer immunotherapy candidate BNT116 in combination with the anti-PD1 cemiplimab in an oral presentation. The update includes safety and clinical activity data, along with biomarker data from a cohort of frail patients with advanced or metastatic non-small cell lung cancer ("NSCLC") who were not eligible for platinum-based chemotherapy as first-line treatment. The preliminary data showed anti-tumor activity, consistent immune response induction, and a manageable safety profile.

Preclinical data for the EpCAMx4-1BB antibody candidate BNT314/GEN1059, which is being developed in collaboration with Genmab A/S ("Genmab"), will be presented in a poster session. BNT314/GEN1059 was evaluated in combination with PD-1 inhibition in a tumor model unresponsive to each single treatment. The data showed anti-tumor activity, delayed tumor outgrowth and prolonged survival for the combination treatment compared to both single treatments. The immunomodulatory activity of BNT314/GEN1059 was further potentiated in combination with PD-1 blockade.

BioNTech has established a diversified oncology portfolio including mRNA cancer immunotherapies, next-generation immunomodulators, and targeted therapies, comprising ADCs and cell therapies, to develop novel treatment approaches for patients living with cancer. The Company is further maturing its clinical oncology pipeline across multiple solid tumor indications, including more than 20 active Phase 2 and Phase 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.

About the KIR-CAR Platform

The KIR-CAR platform is a multi-chain CAR T cell therapy and has been shown in preclinical animal models to be capable of maintaining antitumor T cell activity even in challenging tumor microenvironments. Using NK cell derived KIR and DAP12 split signaling provides a novel combined activation and co-stimulation separate from the usual T cell stimulation pathways. It also enables sustained chimeric receptor expression and improves KIR-CAR T cell long term function. This results in prolonged T cell functional persistence and leads to tumor regression in preclinical models that are resistant to traditional CAR T cell therapies. As a result of decreased T cell exhaustion, KIR-CAR also enables targeting of solid tumors in addition to blood cancers.

On April 23, 2025 Adcendo ApS ("Adcendo"), a biotech company focused on the development of first and best-in-class ADCs for the treatment of cancers with high unmet medical need, reported it will be presenting data on its two novel ADC programs ADCE-T02, targeting Tissue Factor, and ADCE-D01, targeting uPARAP, at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting, held in Chicago, Illinois, from April 25th to April 30th, 2025 (Press release, ADCendo, APR 23, 2025, View Source [SID1234652044]).

ADCE-T02 is a potential best-in-class Topo-1 inhibitor-based ADC targeting Tissue Factor (TF). Tissue Factor is clinically validated target overexpressed in a broad range of solid tumors, with limited expression in normal tissues. ADCE-T02 is composed of a next-generation TF targeting antibody conjugated to an exatecan-based T-1000 payload, a clinically validated linker-payload technology. ADCE-T02 shows strong anti-tumor activity in a wide range of solid tumor models and is well tolerated in non-human primate toxicology studies with no evidence of toxicity from earlier generation TF ADCs. A phase 1 clinical trial in advanced solid tumors is ongoing in both Australia and the United States. Australian recruitment is underway and enrollment in the United States will be initiated in the near future [NCT06597721].

ADCE-D01 is a first-in-class ADC targeting uPARAP conjugated to the Topo-1 inhibitor payload P-1021. uPARAP is a novel endocytic ADC target that is overexpressed in tumors of mesenchymal origin, such as sarcomas, while exhibiting restricted expression in normal tissues. ADCE-D01 is composed of a first-in-class uPARAP-targeting antibody conjugated to an optimized, clinically validated linker payload technology, selected for its superior efficacy and tolerability. Preclinically, ADCE-D01 shows strong anti-tumor activity in a range of mesenchymal tumor models including soft tissue sarcoma and is well tolerated in non-human primate toxicology studies with a favorable safety profile and no evidence of target-specific toxicity. A phase 1 clinical trial in advanced soft tissue sarcomas is enrolling in the United States and is under regulatory review in the European Union [NCT06797999].

Dominik Mumberg, PhD, Chief Scientific Officer at Adcendo, said: "We are excited to share the promising preclinical data for ADCE-T02 and ADCE-D01 demonstrating strong anti-tumor activity across a broad range of epithelial and mesenchymal tumor models with highly favourable tolerability profiles. We look forward to advancing both programs in our phase 1 Tiffany-01 and ADCElerate1 trials to help cancer patients in need of novel therapeutic options."

About antibody-drug conjugates (ADCs):

ADCs are a class of highly potent biopharmaceutical drug composed of a targeting antibody linked to a biologically active drug or cytotoxic compound. ADCs combine the unique and very sensitive targeting capabilities of antibodies, with the potent effects of the conjugated cytotoxic drugs, allowing sensitive discrimination between healthy and cancer tissues.
