BerGenBio Announces Data from Bemcentinib Trial in Mesothelioma Presented at ASCO

- Investigator-led Phase IIa study met its primary endpoint of disease control rate at 12 weeks -


BERGEN, Norway, June 5, 2023 – BerGenBio ASA (OSE: BGBIO), a clinical-stage biopharmaceutical company developing novel, selective AXL kinase inhibitors for severe unmet medical needs, announced that an oral presentation detailing the initial results from a Phase IIa trial evaluating bemcentinib in patients with mesothelioma was presented today at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago.


The abstract, Bemcentinib and pembrolizumab in patients with relapsed mesothelioma: MiST3, a phase IIa trial with cellular and molecular correlates of efficacy, was presented by the study lead investigator, Dr. Matthew Krebs, Ph.D., FRCP, The University of Manchester, UK. MiST, the Mesothelioma Stratified Therapy umbrella trial, led by Professor Dean Fennell at the University of Leicester, UK, is a British Lung Foundation funded study dedicated to improving survival outcomes for patients with mesothelioma. MiST3, the third arm of the trial, was designed to assess the efficacy of AXL/PD-1 inhibition with the combination of BerGenBio’s AXL inhibitor bemcentinib and pembrolizumab.


26 patients with relapsed mesothelioma were enrolled in MiST3 and all received at least one dose of bemcentinib and pembrolizumab. The primary endpoint of disease control rate at 12 weeks (DCR12w) was met: 46.2% (90% CI: 29.2, 63.4). Secondary endpoints included a disease control rate at 24 weeks (DCR24w) of 38.5% (95% CI: 20.2, 59.4) and an overall response rate of (ORR) of 15.4% (95% CI: 4.4, 34.9). The combination of bemcentinib and pembrolizumab was generally safe and well-tolerated.


Dr. Matt Krebs remarked, “We are encouraged by the initial results of the MiST3 trial and believe that this combination warrants further evaluation in patients with relapsed/refractory mesothelioma. While standard PD-1 targeting immunotherapies alone have helped some, the majority of patients are in need of better options. Data continues to point towards AXL inhibition being synergistic with PD-1 inhibition and that it has the potential to add significant benefit to this population.”


“We are quite pleased with the findings and thankful for all of the collaborators in the MiST3 trial,” Martin Olin, Chief Executive Officer of BerGenBio. “These results provide additional evidence of the role of bemcentinib’s AXL inhibition in another aggressive disease such as mesothelioma.”
