After reaching a peak in 2020, antibody dealmaking has continued to thrive, with around 150 deals valued at more than $34 billion in 2021, and more than 75 deals potentially worth over $20 billion in 2022 so far (Fig. 1).

Most of the highest-value deals involving antibodies (Table 1) were in the oncology therapeutic area, with targets including the immune checkpoints PD1 and TIGIT, as well as the folate receptor and 5T4. A handful of deals were in other therapeutic areas, including central nervous system diseases, infectious diseases and skin diseases. Large biopharma companies were involved with all of the top ten deals, including GSK, which signed three of the deals across several areas: neurodegenerative diseases with Alector, oncology with iTeos Therapeutics and respiratory viral infections with Vir Biotechnology.
