OSLO, Norway–(BUSINESS WIRE)–#cancer—NEC OncoImmunity AS (NOI) today announced it has published a study that describes the use of its artificial intelligence (AI) based neoantigen prediction technology to demonstrate that high neoantigen quality in conjunction with infiltration of immune cells in tumors correlates with improved progression free survival (PFS) in sarcoma patients treated with immune checkpoint inhibitors.
The authors sequenced tumor samples and blood from patients who participated in the pivotal SARC028 clinical trial and received the pembrolizumab checkpoint inhibition therapy. They then used their AI-based neoantigen prediction technology, the NEC Immune Profiler, to investigate whether high quality neoantigens in cooperation with the immune cell composition in the tumor improved PFS. Their analysis suggested that the presence of high quality neoantigens together with T cells in tumors are key prognostic markers of PFS. This trend was not observed with the combined presence of T cells and high tumor mutational burden, highlighting the importance of accurate and clinically relevant neoantigen prediction.
The study which was published in Frontiers in Immunology was performed in collaboration with Oslo University Hospital (OUH) in addition to other collaborators from the SARC028 sarcoma clinical trial, including MD Anderson and the University of Pittsburgh Medical center. Professor Ola Myklebost, one of the senior authors in the paper at OUH, and who is currently serving as Professor of molecular oncology at the University of Bergen said:
