On October 28, 2025, GSK and Empirico, a clinical-stage biotechnology company with leading capabilities in human genetics-driven target discovery and siRNA medicines, announced that they have entered into a worldwide exclusive license agreement for EMP-012, a highly selective first- and potentially best-in-class siRNA, a type of oligonucleotide. EMP-012 addresses a novel therapeutic target and is currently in a Phase 1 trial for the treatment of chronic obstructive pulmonary disease (COPD), with the potential for expansion into other inflammatory respiratory diseases. Wilson Sonsini Goodrich & Rosati advised Empirico on the transaction.
EMP-012 utilizes a novel mechanism that targets a specific inflammatory pathway, allowing for treatment that is independent of baseline type 2 inflammation, smoking, or co-morbid conditions. Supported by extensive genetic data, this approach could benefit patients with non-type 2 inflammation, a group with limited treatment options. EMP-012's enhanced potency and longer dosing interval, derived from Empirico’s proprietary siRNA technology, complement GSK’s existing COPD programs, including long-acting biologics. Additionally, EMP-012 offers GSK the flexibility to explore combination therapies within its COPD portfolio.
The agreement grants GSK full worldwide development and commercial rights to EMP-012. Empirico will continue to lead the clinical development of EMP-012 through the completion of the ongoing Phase 1 clinical trial, following which GSK will assume responsibility for worldwide development, regulatory filings, and commercialization. GSK will pay an $85 million upfront payment and up to $660 million in milestone payments, along with royalties on net sales worldwide.
