On June 26, 2018 BerGenBio ASA (OSE:BGBIO) reported that on a top-line, preliminary basis, the first efficacy endpoint has been met in its Phase II clinical trial (BGBC008) evaluating bemcentinib, a first-in-class oral selective AXL inhibitor, in combination with the Merck & Co., Inc., Kenilworth, N.J., USA anti-PD-1 therapy KEYTRUDA (pembrolizumab) as a potential new treatment regimen for advanced non-small cell lung cancer (NSCLC)(Press release, BerGenBio, JUN 26, 2018, View Source [SID1234527463]) . The primary efficacy endpoint requires at least four patients (out of the first 22 treated patients) to achieve clinical responses when treated with the novel drug combination, defined as either complete or partial response, as measured by Response Evaluation Criteria in Solid Tumors (RECIST).

Richard Godfrey, Chief Executive Officer of BerGenBio, commented: "Immunotherapy has become a major component of the treatment of many cancers – patients who respond to immune checkpoint inhibitors like KEYTRUDA enjoy long-term disease control with excellent quality of life. Unfortunately, only a minority of lung cancer patients receiving KEYTRUDA monotherapy in second-line respond to treatment. The BGBC008 combination trial of bemcentinib with KEYTRUDA evaluates whether the addition of our selective AXL inhibitor will improve the outcome of immunotherapy.
"Clearing the first efficacy threshold in this ongoing Phase II trial is very encouraging and we intend to begin enrolment for Stage 2 of this study in which 24 further patients will be enrolled under the same protocol. Thus far, we are delighted to see activity in a number of patients receiving this novel treatment regimen. A particularly encouraging finding is that we see responses in patients who are negative for the PD-L1 biomarker, for whom KEYTRUDA monotherapy is not indicated. The second stage of the trial is intended to confirm activity and biomarker correlation in a larger group of patients – comprehensive analysis of the Phase II data will continue and will be presented at a future scientific conference.
"Successfully completing this important milestone further supports our belief in the potential of bemcentinib to become a cornerstone of cancer therapy. We look forward to sharing more details from our Phase II clinical programme during major clinical conferences in the coming months."
About the BGBC008 trial combining bemcentinib with KEYTRUDA (pembrolizumab) conducted in collaboration with Merck & Co., Inc.
Design
The BGBC008 trial is a Phase II multi-centre open-label study of bemcentinib in combination with KEYTRUDA (pembrolizumab) in previously treated, immunotherapy naïve, patients with advanced adenocarcinoma of the lung, the most common form of non-small cell lung cancer (NSCLC). 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).
A pre-defined efficacy endpoint was set at four or more responses observed in the first 22 patients based on previously reported response rates to KEYTRUDA monotherapy in the second line setting in NSCLC.
Status June 2018
To date, 4 responses (partial responses as per RECIST v1.1) have been observed in the first 22 patients. A number of patients remain ongoing and are awaiting the confirmation of their best response.
Patients generally tolerated the novel drug combination well – no new safety events were reported from the combination of bemcentinib with KEYTRUDA at full dose.
A preliminary interim analysis of the trial (from 15 patients evaluable for response) was presented at ASCO (Free ASCO Whitepaper) 2018, where tumour shrinkage was observed in about half of the patients analysed to date. Results looked particularly promising in patients who did not express the PD-L1 biomarker, i.e. representing 1/3 of NSCLC patients, a group for whom KEYTRUDA monotherapy as a second line is not indicated.
