On November 6, 2019 BerGenBio ASA (OSE:BGBIO), a clinical-stage biopharmaceutical company developing novel, selective AXL kinase inhibitors for multiple cancer indications, reported that the primary endpoint of Overall Response Rate (ORR) has been met in Cohort A of its Phase II clinical trial (BGBC008) evaluating bemcentinib, its first in class selective AXL inhibitor, in combination with the MSD’s, (a tradename of Merck & Co., Inc., Kenilworth, NJ., USA) anti-PD-1 therapy KEYTRUDA (pembrolizumab), as a potential new treatment regimen for previously treated advanced non-small cell lung cancer (NSCLC) (Press release, BerGenBio, NOV 6, 2019, https://www.bergenbio.com/bergenbios-bemcentinib-meets-primary-endpoint-in-first-cohort-of-phase-2-nsclc-study-in-combination-with-keytruda/ [SID1234550445]). The primary efficacy endpoint requires that at least 25% evaluable patients achieve a clinical response when treated with the novel drug combination, defined as either complete or partial response, as measured by Response Evaluation Criteria in Solid Tumors (RECIST).

A secondary endpoint of median Progression Free Survival (mPFS) reported significant 3-fold improvement in AXL positive vs negative patients, as defined by BerGenBio’s composite AXL tumor-immune score.

These data will be presented during at the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) in the High Impact Clinical Trials session on Friday 8 November in a presentation entitled: A phase II study of bemcentinib (BGB324), a first-in-class selective AXL inhibitor, in combination with pembrolizumab in patients with advanced NSCLC: Updated analysis.

Professor Hani Gabra MD PhD, Chief Medical Officer of BerGenBio, commented: "I am impressed by these results that clearly demonstrate the durable clinical benefits in this difficult to treat low PD-L1 patient population. Importantly the patients that benefit most match gene signatures that predict poor prognosis and a lack of response to immunotherapy in NSCLC". ​

Richard Godfrey, Chief Executive Officer of BerGenBio, commented: "I am delighted to see continued significant patient benefit from bemcentinib in combination with Keytruda. This is the first of three cohorts where we are evaluating this combination in previously treated lung cancer patients and I look forward to reporting data from these additional cohorts in the coming months."

About AXL

AXL kinase is a cell membrane receptor and an essential mediator of the biological mechanisms underlying life-threatening diseases. In cancer, AXL suppresses the body’s immune response to tumours and drives cancer treatment failure across many indications. Tumour AXL expression is associated with poor prognosis in NSCLC and most other cancer types. AXL inhibitors, therefore, have potential high value at the centre of cancer combination therapy, addressing significant unmet medical needs and multiple high-value market opportunities. Research has also shown that AXL mediates other aggressive diseases.
