• Additional NSCLC data: Bemcentinib/TARCEVA phase II combination trial in first line EGFRm patients reported that median PFS has surpassed that of TARCEVA monotherapy, encouraging efficacy reported in combination trial with docetaxel in later line patients

Bergen, Norway, 13 November 2018 – BerGenBio ASA (OSE: BGBIO), a clinical-stage biopharmaceutical company developing novel, selective AXL kinase inhibitors for multiple cancer indications, announces its results for the third quarter 2018. A presentation of the results by the Company's management will take place today at 10.00 am CET in Oslo – details below.

Richard Godfrey, Chief Executive Officer of BerGenBio, commented: "We are pleased with the progress of our phase II clinical development programme with our selective AXL inhibitor bemcentinib, particularly in NSCLC. The observed correlation between patient response and positive AXL status in our combination trial with KEYTRUDA gives us confidence in bemcentinib's proposed mode of action and its broad appeal as a promising new agent treating aggressive cancer. The next six to nine months will be an exciting time for the company as we anticipate further clinical data from our phase II trials, particularly in NSCLC and acute myeloid leukaemia."

About AXL

AXL kinase is a cell membrane receptor and an essential mediator of the biological mechanisms that drive aggressive and life-threatening diseases. In cancer, AXL drives tumour survival, treatment resistance and spread, as well as suppressing the body's immune response to tumours. AXL expression has been established as a negative prognostic factor in many cancers. AXL inhibitors, therefore, have potential value at the centre of cancer combination therapy, addressing significant unmet medical needs and multiple high-value market opportunities.

About BerGenBio ASA

BerGenBio is a clinical-stage biopharmaceutical company focused on developing transformative drugs targeting AXL as a potential cornerstone of therapy for advanced and aggressive cancers. The company's proprietary lead candidate, bemcentinib, is a potentially first-inclass selective AXL inhibitor in a broad phase II clinical development programme. Ongoing clinical trials are investigating bemcentinib in multiple solid and haematological tumours, in combination with current and emerging therapies (including immunotherapies, targeted therapies and chemotherapy), and as a single agent.

In parallel, BerGenBio is developing a companion diagnostics test to identify patient populations most likely to benefit from bemcentinib: this is expected to facilitate more efficient registration trials and support 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). www.bergenbio.com
