For World Cancer Day 2024, The Antibody Society has prepared a snapshot of the clinical development of therapeutic antibodies for cancer indication.
The infographic gives an overview on the trends in first in human studies and approvals, as well as on the active early and late stage pipelines (as of January 2024).
In this 15th installment of the annual ‘Antibodies to Watch’ article series, we review commercially sponsored monoclonal antibody therapeutics currently in late-stage clinical development, regulatory review, and those granted a first approval in any country in 2023. We also discuss clinical phase transition and overall approval success rates for antibody therapeutics, which are crucial to the biopharmaceutical industry because these rates inform decisions about resource allocation. Our analyses indicate that these molecules have approval success rates in the range of 14–32%, with higher rates associated with antibodies developed for non-cancer indications. Overall, our data suggest that antibody therapeutic development efforts by the biopharmaceutical industry are robust and increasingly successful.
The complete abstract is here: The ‘Antibodies to Watch’ article series provides an annual summary of commercially sponsored monoclonal antibody therapeutics currently in late-stage clinical development, regulatory review, and those recently granted a first approval in any country. In this installment, we discuss key details for 16 antibody therapeutics granted a first approval in 2023, as of November 17 (lecanemab (Leqembi), rozanolixizumab (RYSTIGGO), pozelimab (VEOPOZ), mirikizumab (Omvoh), talquetamab (Talvey), elranatamab (Elrexfio), epcoritamab (EPKINLY), glofitamab (COLUMVI), retifanlimab (Zynyz), concizumab (Alhemo), lebrikizumab (EBGLYSS), tafolecimab (SINTBILO), narlumosbart (Jinlitai), zuberitamab (Enrexib), adebrelimab (Arelili), and divozilimab (Ivlizi)). We briefly review 26 product candidates for which marketing applications are under consideration in at least one country or region, and 23 investigational antibody therapeutics that are forecast to enter regulatory review by the end of 2024 based on company disclosures. These nearly 50 product candidates include numerous innovative bispecific antibodies, such as odronextamab, ivonescimab, linvoseltamab, zenocutuzumab, and erfonrilimab, and antibody–drug conjugates, such as trastuzumab botidotin, patritumab deruxtecan, datopotamab deruxtecan, and MRG002, as well as a mixture of two immunocytokines (bifikafusp alfa and onfekafusp alfa). We also discuss clinical phase transition and overall approval success rates for antibody therapeutics, which are crucial to the biopharmaceutical industry because these rates inform decisions about resource allocation. Our analyses indicate that these molecules have approval success rates in the range of 14–32%, with higher rates associated with antibodies developed for non-cancer indications. Overall, our data suggest that antibody therapeutic development efforts by the biopharmaceutical industry are robust and increasingly successful.

“Antibodies to Watch in 2023” highlights key events in commercial monoclonal antibody therapeutics development that occurred in 2022 and forecasts events that might occur in 2023. In this presentation, we will discuss the antibody therapeutics granted first approvals in either the United States or European Union in 2022, which include 4 bispecific antibodies ((tebentafusp, faricimab, mosunetuzumab and teclistamab) and 1 ADC (mirvetuximab soravtansine). We will also discuss approvals for antibody therapeutics that were first granted in China or Japan in 2022, which include 2 bispecific antibodies (cadonilimab and ozoralizumab). Globally, at least 24 investigational antibody therapeutics are undergoing review by regulatory agencies. Our data show that, with antibodies for COVID-19 excluded, the late-stage commercial clinical pipeline grew by ~20% in the past year to include nearly 140 investigational antibody therapeutics that were designed using a wide variety of formats and engineering techniques. Of those in late-stage development, marketing application submissions for at least 23 may occur by the end of 2023, of which 5 are bispecific (odronextamab, erfonrilimab, linvoseltamab, zanidatamab, and talquetamab) and 2 are ADCs (datopotamab deruxtecan, and tusamitamab ravtansine).

Novel therapeutic modalities such as bispecific antibodies are increasingly being explored as more effective alternatives to monoclonal antibodies for a range of diseases. Therapeutics such as bispecifics, can have a combinatorial effect by targeting two antigens, resulting in treatments with enhanced utility, higher efficacy, fewer side effects and less resistance compared to mAbs.
Generating a bispecific antibody, which is correctly and stably paired, is a major production concern. Many solutions require significant changes to native antibody structure, which increases antibody complexity and forces adaptation of downstream processes. While a various platforms have been developed to mitigate Heavy-Light chain (HC-LC) mispairing, there are many other rate limiting steps for efficiently expressing these molecules in a CHO system. bYlok® technology is a design engineering approach that stabilise the interaction between the HC and LC, essentially removing the mispairing problem whilst retaining a more natural antibody structure.
This presentation will introduce you to a mechanistic review of the bispecific pipeline to demonstrate how a various tools and technologies can enable you execute bispecifics. Case studies will be presented to show how the bYlok® technology can be used to stabilise and select for novel bispecifics from a panel of parental immunotherapeutic mAbs. Our data demonstrates that correct heterodimerisation can be achieved consistently and how standard downstream purification processes can be used during production.
The On Demand version of this webinar is now available.In “Antibodies to Watch in 2022”, Drs. Janice Reichert, Alicia Chenoweth and Silvia Crescioli discuss key events in antibody therapeutics development that occurred in 2021 and forecast events that might occur in 2022. The COVID-19 pandemic continued to pose challenges and opportunities to the healthcare system, but companies forged ahead with development plans, resulting in record numbers of antibody therapeutics in late-stage clinical studies and in regulatory review. Globally, regulatory agencies approved a record number of novel antibody-based products, including anti-SARS-CoV-2 antibodies. The speakers provide details of 2021 events and trends in the development of antibody therapeutics projected for 2022.
