ITC opens trade-secrets investigation
If you make, import, or sell certain antibody drug products, the U.S. International Trade Commission started an investigation on December 17, 2025 (Investigation No. 337-TA-1466) based on a complaint filed November 18, 2025 alleging misappropriation of trade secrets. The complainants (AbbVie and ImmunoGen) asked the Commission to investigate and to consider orders to block unfairly imported products.
Investigation targets Rina-S ADC and components
The investigation specifically covers certain antibody drug conjugates called Rina-S (also known as "rinatabart sesutecan," "PRO1184," or "GEN1184"), fragments of the intact Rina-S that include the linker (including the linker alone, linker bound to the antibody, or linker bound to the drug payload), and products containing them used in treating ovarian cancer. Companies working with these named products are within the scope of the case.
Respondents must answer within 20 days or risk default
Named respondents must file responses in accordance with 19 CFR 210.13 and those responses will be considered only if received no later than 20 days after service of the complaint and notice of investigation. The notice says extensions will not be granted unless good cause is shown, and failure to file a timely response may be treated as a waiver and could lead to an initial and final determination and issuance of exclusion or cease-and-desist orders.
