Agenus Inc

Agenus, Inc. is a clinical-stage biotechnology company focused on discovering and developing immuno-oncology therapies, with R&D centered largely on antibody programs. The company’s activities span research, preclinical and clinical development, manufacturing, regulatory and clinical affairs, and intellectual property prosecution, with a business model that mixes internal development with collaborations and licensing. A distinctive feature of its reported revenue is non-cash royalty revenue tied to GSK vaccines that include Agenus’ STIMULON QS-21 adjuvant, even though the underlying royalties were sold to a third party (HCR) and are remitted directly to HCR. Agenus’ ability to fund operations and progress programs depends heavily on clinical and regulatory outcomes, collaboration milestones, and periodic capital raises and partner funding.
