BerGenBio: Promising data highlighting selective AXL inhibitor bemcentinib’s potential to improve efficacy of checkpoint inhibitors presented at AACR

Bergen, Norway, 18 April 2018 – BerGenBio ASA (OSE: BGBIO), a clinical-stage biopharmaceutical company developing novel, selective AXL kinase inhibitors for multiple cancer indications, announces that promising preclinical data with its lead AXL inhibitor bemcentinib (formerly BGB324) has been presented in a poster at the 2018 American Association for Cancer Research (AACR) Annual Meeting on 14-18 April in Chicago, IL, USA.

The data highlight bemcentinib’s potential to reverse tumour immune suppression and enhance immune checkpoint inhibitor efficacy.

The authors show that bemcentinib targets immune suppression mechanisms in the tumour microenvironment that improve immunotherapy in murine tumour models of non-small cell lung (NSCLC), triple negative breast (TNBC) and pancreatic cancer. Bemcentinib treatment reduces myeloid-derived suppressor cells and the altered immune landscape is associated with increased tumour infiltration of T cells (NK and CD8+) and enhanced therapy responses.

A validated AXL immunohistochemistry (IHC) method for use on patient samples to identify the presence of AXL on tumour cells and immune cells in the tumour microenvironment was presented. The authors report that across 92 banked tumour biopsies from patients with TNBC or NSCLC 70% were found to stain positive for AXL using this IHC method. The IHC method is now in use to analyse biopsies taken in connection with the company’s phase II combination trials of bemcentinib with KEYTRUDA® in patients with advanced NSCLC or TNBC.

Professor James Lorens, BerGenBio Chief Scientific Officer, commented: “These results highlight a clear and important role for AXL in aggressive disease and resistance to immune therapy in particular. They provide continued confidence in the potential of combining bemcentinib with immune checkpoint inhibitors to improve cancer treatment, and support for our Phase II clinical trial programme of bemcentinib combined with the blockbuster immune checkpoint inhibitor KEYTRUDA, interim results from which are expected during 2018.”

About BerGenBio ASA 

BerGenBio ASA is a clinical-stage biopharmaceutical company focused on developing a pipeline of first-in-class AXL kinase inhibitors as a potential cornerstone of combination cancer therapy. The Company is a world leader in understanding the essential role of AXL kinase in mediating cancer spread, immune evasion and drug resistance in multiple aggressive solid and haematological cancers.

BerGenBio’s lead product, bemcentinib (BGB324), is a selective, potent and orally bio-available small molecule AXL inhibitor in four Company sponsored Phase II clinical trials in major cancer indications, with read-outs anticipated during 2018. It is the only selective AXL inhibitor in clinical development.

The Company sponsored clinical trials are:

  • Bemcentinib with TARCEVA® (erlotinib) in advanced EGFR mutation driven non-small cell lung cancer (NSCLC)
  • Bemcentinib with KEYTRUDA in advanced adenocarcinoma of the lung, and
  • Bemcentinib with KEYTRUDA in triple-negative breast cancer (TNBC).
  • Bemcentinib as a single agent and combination therapy in acute myeloid leukaemia (AML) / myeloid dysplastic syndrome (MDS)

The clinical trials combining bemcentinib with KEYTRUDA in adenocarcinoma of the lung and TNBC are conducted in collaboration with Merck & Co., Inc. (Kenilworth, NJ, USA), through a subsidiary.

In addition, a number of investigator-sponsored trials are underway, including a trial to investigate bemcentinib with either MEKINIST® (trametinib) plus TAFINLAR® (dabrafenib) or KEYTRUDA in advanced melanoma, as well as a trial combining bemcentinib with docetaxel in advanced NSCLC.

BerGenBio is simultaneously developing a companion diagnostic test to identify patient subpopulations most likely to benefit from treatment with bemcentinib. This will facilitate more efficient registration trials and support a precision medicine based commercialization strategy.

The Company is also developing a diversified pre-clinical pipeline of drug candidates, including BGB149, an anti-AXL monoclonal antibody.
