Artificial intelligence has greatly improved therapeutic antibody development, not only in discovery and affinity maturation, but increasingly in assessing developability. Developability screening typically relies on resource-intensive workflows, which could delay key decisions about candidate selection until late in the pipeline.
Antibody affinity is a core metric in immunology and biopharmaceutical science. It refers to the strength of the interaction between a single antigen epitope and the paratope (binding site) of an antibody. In the case of VHH antibodies, also called single-domain antibodies or nanobodies, this interaction occurs through the unique, compact paratope located on their heavy-chain-only variable domain.
A roundup of the biggest antibody biotech and pharma deals in December 2025.
The antibody therapeutics landscape continues to evolve rapidly, with 2026 marking notable progress in clinical approvals, pipeline expansions, and novel engineering strategies. This year’s developments reflect the industry’s growing focus on bispecific antibodies, antibody-drug conjugates (ADCs), and next-generation immune-modulating biologics.
Antibody discovery and development remain strategic priorities for major pharmaceutical companies, as evidenced by the significant deal activity in 2025. While the broader biotech sector faced macroeconomic headwinds, antibody-based therapeutics, particularly bispecific antibodies, antibody-drug conjugates (ADCs), and Fc-fusion constructs, continued to attract substantial investment.
VHH antibodies are single-domain antibody fragments derived from the unique heavy-chain-only antibodies (HCAbs) of camelids, including alpacas, llamas, and camels.
As of the end of 2025, 21 ADCs have been approved globally, with four new approvals added in 2025 alone. Antibody-drug conjugates (ADCs) are a class of targeted biotherapeutics that combine the specificity of monoclonal antibodies with the cytotoxic potency of small molecule drugs.
Antibody engineering has progressed beyond classical depletion and neutralization strategies to encompass diverse modalities that engage immune tolerance, tissue-specific immunomodulation, and tumor immunity.
The 2025 Antibody Engineering & Therapeutics US (AET US) conference was held in San Diego on December 14-17, 2025. The event theme was "Accelerating Tomorrow's Antibody Therapeutics Today".
The 2025 mAbTalk Symposium by The Chinese Antibody Society was held in San Deigo, CA, on December 14, 2025. The event focused on “Novel Modalities in the Frontier of Antibody Therapeutics”, with 100+ attendees and 15+ sponsors in attendance.
On Friday, December 12th, 2025, Biointron celebrated the end of the year with a spectacular annual year-end networking party at Boston Marriott Newton in Boston. Bringing together industry professionals, partners, and clients, the event celebrated Biointron’s achievements and hosted two exciting guest speaker presentations.
