About Bemcentinib

Bemcentinib is a potentially first-in-class, potent and highly selective
inhibitor of the tyrosine kinase AXL.  Extensive studies confirm the ability to
combine bemcentinib with immune checkpoint inhibitors, chemotherapies and
targeted therapies with the goal of improving a patient's immune response and
delaying the development of chemoresistance.  Bemcentinib is currently being
investigated in combination with immune checkpoint inhibition and chemotherapy
in first line NSCLC patients harboring mutations in the STK11 gene, a known
prognostic factor of poor response to existing therapies.

About BerGenBio ASA

BerGenBio is a clinical-stage biopharmaceutical company focused on developing
transformative drugs targeting AXL as a potential cornerstone of therapy for
aggressive diseases, including cancer and severe respiratory infections. The
Company is focused on its proprietary lead candidate, bemcentinib, a potentially
first-in-class selective AXL inhibitor in development for STK11 mutated NSCLC
and COVID-19.
