Builds clinical-stage immunology medicines rather than an owned commercial product franchise. The pipeline centers on tobevibart plus elebsiran for chronic hepatitis delta, PRO-XTEN masked T-cell engagers for solid tumors, and preclinical HIV antibody candidates, with revenue still tied mainly to collaborations, licenses, and grants.
Operates as a clinical-stage immunology company with a single reportable segment focused on discovering and developing medicines for serious infectious diseases and cancer. Current programs center on tobevibart plus elebsiran for chronic hepatitis delta, PRO-XTEN masked T-cell engagers for solid tumors, and HIV antibody candidates with the Gates Foundation.
The business is not built around owned product sales yet. Recent revenue came from license, collaboration, grant, and other sources, including the Norgine agreement covering commercial rights for the hepatitis delta combination in Europe, Australia, and New Zealand.
Execution depends on clinical readouts, partner rights, and access to external technology: elebsiran is licensed from Alnylam, the PRO-XTEN platform came from Sanofi, and Astellas holds rights for VIR-5500 in prostate cancer.
