Eiger BioPharmaceuticals: core business model

Eiger BioPharmaceuticals operates as a clinical?stage biotechnology company focused on developing and commercializing targeted therapies for rare and serious diseases, with an emphasis on liver? and infectious?disease indications.Eiger BioPharmaceuticals IR as of 2026

Main revenue and product drivers for Eiger BioPharmaceuticals
