Business Model
What each company does and how it makes money
CytomX Therapeutics is an oncology-focused biopharmaceutical company that develops conditionally activated antibody therapeutics using its proprietary Probody technology platform. It generates revenue primarily through strategic collaborations and licensing deals with major pharmaceutical partners — including AbbVie, Amgen, and Bristol-Myers Squibb — which provide upfront payments, milestone payments, and potential future royalties on any commercialized products. The company's key competitive advantage is its Probody platform technology, which creates conditionally activated therapeutics that remain inactive until they reach the tumor microenvironment, potentially improving safety and efficacy compared to traditional antibody therapies.
Celldex Therapeutics is a clinical-stage biopharmaceutical company developing targeted antibody therapies for cancer and inflammatory diseases. It generates revenue primarily through research collaborations and licensing agreements — with future income dependent on successful clinical development and commercialization of its pipeline candidates. The company's competitive advantage lies in its proprietary antibody platform technology and focused expertise in developing monoclonal and bispecific antibodies against validated targets.
