Bergen, Norway, 11 February 2020 - BerGenBio ASA (OSE:BGBIO), a clinical-stage
biopharmaceutical company developing novel, selective AXL kinase inhibitors for
multiple cancer indications, announces its results for the fourth quarter and
full year 2019.

A presentation and live webcast by the Company's management will take place
today at 10.00 am CET in Oslo, please see below for details.

Richard Godfrey, Chief Executive Officer of BerGenBio, commented: "I am pleased
to report on another eventful quarter for BerGenBio. During the period
bemcentinib was approved for Fast Track Designation by the USA FDA for AML, and
we continued to see encouraging data emerge from our ongoing phase II clinical
trials with bemcentinib. The primary endpoint was met in our lung cancer trail
in combination with Merck's checkpoint inhibitor Keytruda®. We were particularly
pleased to see responses among patients for whom checkpoint inhibitors would not
usually be expected to be effective. In January we reported achieving a similar
endpoint in NSCLC patients who had previously relapsed on checkpoint inhibitors.
Looking forward, we anticipate reporting clinical and translational data updates
at medical conferences, later in the year. In January we closed a PIPE funding
providing an additional NOK 220m, subject to EGM approval, such that the Company
is well-financed well beyond current milestones."

Operational Highlights - fourth quarter and full year 2019

  · Bemcentinib met primary endpoint in first cohort of Phase II NSCLC study in
combination with KEYTRUDA®

  · Primary endpoint, Overall Response Rate, was been met in predominantly PD-L1
negative/low patients
  · Secondary endpoint, median Progression Free Survival, exceeds expectations
in AXL positive patients
  · Data was presented at Society for Immunotherapy of Cancer 34th Annual
Meeting on 8 November 2019

  · Preliminary clinical data from Phase II combination trial of bemcentinib and
LDAC in elderly AML patients at ASH 2019

  · Phase II trial data showed bemcentinib in combination with low-dose
cytarabine (LDAC) in elderly AML patients unfit for intensive therapy is well
tolerated and shows promising efficacy
  · Long duration of response (>9.9 mo., still maturing) with 50% complete
response (CR/Cri) in 6 evaluable newly diagnosed patients receiving the
bemcentinib-LDAC combination
  · Clinical benefit demonstrated in >2L relapsed and refractory AML patients
with 1 CR/CRi and 3 SD out of 6 evaluable patients
  · Data presented in a poster presentation at the 61st Annual American Society
of Hematology (ASH) Meeting, on 7-10 December in Orlando, Florida.

  · U.S. Food and Drug Administration (FDA) approved Fast Track Designation for
bemcentinib for the treatment of elderly patients with acute myeloid leukaemia
(AML) whose disease has relapsed.

With this Fast Track designation, BGB is eligible for:

  · More frequent meetings with FDA to discuss the drug's development plan and
ensure collection of appropriate data needed to support drug approval
  · Eligibility for Accelerated Approval and Priority Review

  · Clinical trial updates were presented at several major cancer scientific
congresses and consistently confirm that NSCLC and AML are the optimal target
indications

  · Phase II development programme read-outs according to plan

  · AML bemcentinib + LDAC: readouts at American Society of Clinical Oncology
(ASCO) and European Haematology Association (EHA)
  · NSCLC bemcentinib + KEYTRUDA: readouts at ASCO, World Conference on Lung
Cancer (WCLC), European Society of Medical Oncology (ESMO), The Society for
Immunotherapy of Cancer (SITC)

  · Proprietary composite AXL tumour-immune (cAXL) score developed to identify &
diagnose patients that show durable benefit
  · Completed Phase Ia trial with tilvestamab (BGB149) in healthy volunteers
  · Continued to build out the organisation with strategic medical, clinical,
operational and regulatory hires
  · Private placement completed in June, raising NOK 74.2 million

Q4 2019 / FY 2019 Financial Highlights

(Figures in brackets = same period 2018 unless otherwise stated)

  · Revenue amounted to NOK 0.2 million (NOK 2.3 million) for the fourth quarter

53.2 million) and total operating expenses for the full year 2019 amounted to
213.3 million (NOK 196.9 million)

expenses in the full year 2019
  · The operating loss for the quarter came to NOK 59.1 million
(NOK 50.9 million) and NOK 204.4 million (NOK 194.5 million) for the full year

About BerGenBio

BerGenBio is a clinical-stage biopharmaceutical company focused on developing
transformative drugs targeting AXL as a potential cornerstone of therapy for
aggressive diseases, including immune-evasive, therapy resistant cancers. The
company's proprietary lead candidate, bemcentinib, is a potentially first-in
-class selective AXL inhibitor in a broad Phase II oncology clinical development
programme focused on combination and single agent therapy in lung cancer and
leukaemia. A first-in-class functional blocking anti-AXL antibody, tilvestamab,
is undergoing Phase I clinical testing. In parallel, BerGenBio is developing
companion diagnostic tests to identify those patient populations most likely to
benefit from bemcentinib: this is expected to facilitate more efficient
registration trials supporting a precision medicine-based commercialisation
strategy. 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
