- Distinguished global experts appointed to strengthen bemcentinib development in STK11m NSCLC -

BERGEN, Norway, February 2, 2023 - BerGenBio ASA (OSE: BGBIO), a clinical-stage biopharmaceutical company developing novel, selective AXL kinase inhibitors for severe unmet medical needs, today announced the formation of a scientific advisory board consisting of four world-renowned non-small cell lung cancer (NSCLC) experts from top oncology centers around the globe to enhance the development of bemcentinib for the treatment of NSCLC patients with STK11 mutations (STK11m).

"We are very proud and honored to have assembled a group of leading international NSCLC experts to guide us as we investigate bemcentinib in 1st line NSCLC STK11m in combination with today's standard of care," said Cristina Oliva, M.D., Chief Medical Officer of BerGenBio. "Their expertise will play an integral role in our evaluation of bemcentinib and its potential to provide significant benefits to patients who today face a particularly poor prognosis."

Despite significant advances in immuno-oncology treatments, NSCLC is still one of the leading causes of cancer-related deaths worldwide. Patients harboring STK11m, which represent approximately ~20% of non-squamous NSCLC cases, almost universally demonstrate high levels of AXL activation and show lower response rates to current standard of care therapy of anti-PD-1/L1 combined with chemotherapy. BerGenBio's lead compound, bemcentinib, is designed to selectively inhibit AXL, which may potentially sensitize STK11m NSCLC patients to checkpoint inhibitors and improve the effects of chemotherapy. The Company has initiated a global Phase 1a/2b trial to assess bemcentinib with standard of care in 1st line NSCLC patients with STK11m.
