On May 8, 2019 BerGenBio ASA (OSE: BGBIO) reported that it has completed enrolment into the second stage of its Phase II trial (BGBC008, Cohort A NCT03184571) evaluating the Company’s selective AXL inhibitor bemcentinib in combination with MSD’s anti-PD-1 therapy, KEYTRUDA (pembrolizumab), in patients with previously treated advanced adenocarcinoma of the lung (non-small cell lung cancer, NSCLC) whose disease is progressing on or after prior systemic chemotherapy (Press release, BerGenBio, MAY 8, 2019, View Source [SID1234535901]).

The trial has previously met the efficacy endpoint in the first stage and reported preliminary efficacy including a 40% ORR and 5.9 months Progression-free survival (PFS) in AXL positive patients (n=10). The second stage of the trial enrolling a further 24 patients for a total of 48 is designed to confirm the safety, clinical efficacy and biomarker correlation of the combination.

Comprehensive exploratory studies will continue to evaluate biomarkers in tumour and blood indicative of AXL expression and immune modulation. Results from the trial are expected during 2019.

The trial, which began in October 2017, is being conducted under a clinical collaboration with Merck & Co., Inc., Kenilworth, N.J., USA, through a subsidiary, and is taking place at sites in the US, UK, Norway and Spain.

Richard Godfrey, Chief Executive Officer of BerGenBio, commented: "A majority of NSCLC patients now receive anti-PD(L)-1 therapies like KEYTRUDA as a first- or second-line treatment for their advanced disease. Enhancing responses to these novel agents, particularly in patients with no or limited expression of PD-L1, the established biomarker for these drugs, is a significant unmet need. I am encouraged by the efficacy signals seen during stage 1 of the trial, particularly in AXL positive, and often PD-L1 negative or low, patients and look forward providing data from an extended dataset during the coming months together with further details on our late stage strategy in this indication."

About NSCLC
It is estimated that more than 230,000 new cases of lung cancer have been diagnosed in the US in 2018 and it is the leading cause of cancer deaths. 65% of NSCLCs are of adenocarcinoma pathology. Although various treatments exist for NSCLC, they are often curtailed by acquired resistance to therapy and immune evasion. Novel treatments overcoming these mechanisms in NSCLC are urgently required.

About the BGBC008 trial
The BGBC008 trial is a Phase II open-label study of bemcentinib in combination with KEYTRUDA (pembrolizumab) in previously treated patients with advanced adenocarcinoma of the lung run at centres in the US, UK, Spain and Norway. The objective of the trial is to determine the anti-tumour activity of this novel drug combination and responses will be correlated with biomarker status (including AXL kinase and PD-L1 expression).

Patients eligible for participation in Cohort A must have progressed on or after prior therapy excluding immunotherapy whereas patients in Cohort B will be actively progressing on a therapy regimen containing an anti-PD(L)-1 therapy.

Both cohorts follow a two-stage design, Cohort A has previously successfully progressed into the second stage after meeting its first efficacy endpoint. Cohort B will evaluate advancement into stage 2 after 13 patients have been assessed for response.

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.
