The global market size of bispecific antibody new drugs exceeded 10 billion US dollars in the first half of 2026
In the first half of 2026, the global market size of bispecific antibody new drugs reached 9.839 billion US dollars. Since companies including Akeso did not disclose their specific sales data, the actual market size of bispecific antibody new drugs has exceeded 10 billion US dollars, and it is projected to surpass 20 billion US dollars for the whole year for the first time.
Roche's FIX/FX remains the best-selling new drug worldwide, with sales of 3.279 billion US dollars in the first half of the year, representing an 11% year-on-year increase. The VEGF/Ang2 bispecific antibody ranks as the second top-selling bispecific new drug, with sales of 2.642 billion US dollars in the first half of the year. The combined sales of the two drugs reached 5.921 billion US dollars, accounting for 60% of the total bispecific antibody new drug market.
Amgen's hematological tumor TCE bispecific antibodies Blincyto and the first solid tumor TCE bispecific antibody Imdelltra are both growing at a high speed, with their first-half sales reaching as high as 887 million US dollars and 543 million US dollars respectively, both of which are at the blockbuster level.
All three of Johnson & Johnson's bispecific antibodies — EGFR/cMET, BCMA/CD3 and GPRC5D/CD3 — are growing at a high speed. The first two of them will both reach blockbuster drug status this year.
For a long period of time, the global bispecific antibody new drug market was almost entirely dominated by Roche's two non-oncology bispecific antibodies targeting FIX/FX and VEGF/Ang2. Today, the bispecific antibody new drug sector has entered a new era of all-round prosperity, with 6 bispecific new drugs set to reach blockbuster status this year. Tumor-targeting bispecific antibodies, including TCE bispecifics, have entered a phase of rapid volume expansion. In addition, Akeso's PD-1/VEGF bispecific antibody represents the IO2.0 trend, and its US market launch will usher in a new round of growth for the bispecific antibody new drug market.
