· Bemcentinib is an oral highly selective AXL inhibitor in development for
cancer and severe respiratory infections
  · Final Phase 2 data indicates a favorable safety profile with promising
efficacy in AML and MDS patients

BERGEN, Norway, December 11, 2023, - BerGenBio ASA (OSE: BGBIO), a clinical
-stage biopharmaceutical company developing novel, selective AXL kinase
inhibitors for severe unmet medical needs, today announced that a poster
highlighting final results from a Phase 2 clinical study of its highly selective
AXL inhibitor bemcentinib in patients with Acute Myeloid Leukemia (AML) or
Myelodysplastic Syndrome (MDS) was presented during the 2023 American Society of
Hematology (ASH) Annual Meeting being on December 9th in San Diego, CA.

The data presented by Professor Sonja Loges, MD, Ph.D. of the University Medical
Centre Mannheim, Heidelberg, Germany, showed that bemcentinib was well tolerated
in AML and MDS patients. Durable responses were observed across all cohorts with
bemcentinib as monotherapy and in combination with chemotherapy. In addition,
longitudinal samples analyzed from patients enrolled in the study showed that
bemcentinib inhibited pAXL and downstream markers of activation.

Martin Olin, Chief Executive Officer of BerGenBio commented "This large Phase 2
study included 122 patients in several cohorts of AML and MDS patients treated
with bemcentinib monotherapy or in combination with two different
chemotherapies.  We are particularly encouraged by the monotherapy activity of
bemcentinib in this study which adds to the mounting evidence of the role of
bemcentinib in restoring the function of patients' immune response to cancer."

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.

BerGenBio is based in Bergen, Norway with a subsidiary in Oxford, UK. The
company is listed on the Oslo Stock Exchange (ticker: BGBIO). For more
