Antibodies to watch in 2025

Review

Author: Kapoor, Vaishali ; Kaplon, Hélène ; Crescioli, Silvia ; Reichert, Janice M. ; Visweswaraiah, Jyothsna ; Wang, Lin

The commercial development of antibody therapeutics is a global enterprise involving thousands of biopharmaceutical firms and supporting service organizations. To date, their combined efforts have resulted in over 200 marketed antibody therapeutics and a pipeline of nearly 1,400 investigational product candidates that are undergoing evaluation in clinical studies as treatments for a wide variety of diseases. Here, we discuss key events in antibody therapeutics development that occurred during 2024 and forecast key events related to the late-stage clinical pipeline that may occur in 2025. In particular, we report on 21 antibody therapeutics granted a first approval in at least one country or region during 2024, including bispecific antibodies tarlatamab (IMDELLTRA®), zanidatamab (Ziihera®), zenocutuzumab (BIZENGRI®), odronextamab (Ordspono®), ivonescimab (®), and antibody-drug conjugate (ADC) sacituzumab tirumotecan (®). We also discuss 30 investigational antibody therapeutics for which marketing applications were undergoing review by at least one regulatory agency, as of our last update on December 9, 2024, including ADCs datopotamab deruxtecan, telisotuzumab vedotin, patritumab deruxtecan, trastuzumab botidotin, becotatug vedotin, and trastuzumab rezetecan. Of 178 antibody therapeutics we include in the late-stage pipeline, we summarize key data for 18 for which marketing applications may be submitted by the end of 2025, such as bi- or multispecific antibodies denecimig, sonelokimab, erfonrilimab, and anbenitamab. Key trends in the development and approval of antibody formats such as bispecifics and ADCs, as well as clinical-phase transition and global approval success rates for these antibody formats, are reported.

Discovery of a novel highly specific, fully human PSCA antibody and its application as an antibody-drug conjugate in prostate cancer

Article

Author: Liu, Xianglei ; Mellors, John W. ; Chen, Chuan ; Dimitrov, Dimiter S. ; Zhang, Liyong ; Baek, Du-San ; Hines, Maggie ; Kim, Ye-Jin ; Shin, Seungmin ; Shi, Megan ; Jelev, Dontcho V. ; Adams, Cynthia ; Sun, Zehua ; Li, Wei ; Chu, Xiaojie ; Conard, Alex

Prostate stem cell antigen (PSCA) is expressed in all stages of prostate cancer, including in advanced androgen-independent tumors and bone metastasis. PSCA may associate with prostate carcinogenesis and lineage plasticity in prostate cancer. PSCA is also a promising theranostic marker for a variety of other solid tumors, including pancreatic adenocarcinoma and renal cell carcinoma. Here, we identified a novel fully human PSCA antibody using phage display methodology. The structure-based affinity maturation yielded a high-affinity binder, F12, which is highly specific and does not bind to 6,000 human membrane proteins based on a membrane proteome array assay. F12 targets PSCA amino acids 63-69 as tested by the peptide scanning microarray, and it cross-reacts with the murine PSCA. IgG1 F12 efficiently internalizes into PSCA-expressing tumor cells. The antimitotic reagent monomethyl auristatin E (MMAE)-conjugated IgG1 F12 (ADC, F12-MMAE) exhibits dose-dependent efficacy and specificity in a human prostate cancer PC-3-PSCA xenograft NSG mouse model. This is a first reported ADC based on a fully human PSCA antibody and MMAE that is characterized in a xenograft murine model, which warrants further optimizations and investigations in additional preclinical tumor models, including prostate and other solid tumors.

CD20 expression regulates CD37 levels in B-cell lymphoma – implications for immunotherapies

Rituximab (RTX) plus chemotherapy (R-CHOP) applied as a first-line therapy for lymphoma leads to a relapse in approximately 40% of the patients. Therefore, novel approaches to treat aggressive lymphomas are being intensively investigated. Several RTX-resistant (RR) cell lines have been established as surrogate models to study resistance to R-CHOP. Our study reveals that RR cells are characterized by a major downregulation of CD37, a molecule currently explored as a target for immunotherapy. Using CD20 knockout (KO) cell lines, we demonstrate that CD20 and CD37 form a complex, and hypothesize that the presence of CD20 stabilizes CD37 in the cell membrane. Consequently, we observe a diminished cytotoxicity of anti-CD37 monoclonal antibody (mAb) in complement-dependent cytotoxicity in both RR and CD20 KO cells that can be partially restored upon lysosome inhibition. On the other hand, the internalization rate of anti-CD37 mAb in CD20 KO cells is increased when compared to controls, suggesting unhampered efficacy of antibody drug conjugates (ADCs). Importantly, even a major downregulation in CD37 levels does not hamper the efficacy of CD37-directed chimeric antigen receptor (CAR) T cells. In summary, we present here a novel mechanism of CD37 regulation with further implications for the use of anti-CD37 immunotherapies.
