Novigenix Announces Discovery of Liquid Biopsy Immunotherapy Response Biomarkers in Metastatic Melanoma (Novigenix Press Release)
"A study was conducted with 29 BRAF+ and high lactate hydrogenase MM patients, treated with anti-PD-1/CTLA-4 therapy (ipi+nivo). Whole blood Immuno-Transcriptome profiles were analyzed before and after 6 weeks of combination therapy on the LITOseek platform of Novigenix for discovery of response prediction biomarkers and monitoring of patients following treatment, with clinical benefit defined as Progression-Free Survival (PFS) ≥ 6 months. A panel of 119 genes were identified for prediction of clinical benefit from combination therapy with an area under the curve (AUC) of 0.98. Functional analysis in responsive patients suggest upregulation of gene clusters involved in ribosomal biogenesis and TCR signaling, and downregulation of interferon gene clusters. A panel of 114 biomarkers identified for patient monitoring during ICI therapy further indicate upregulated gene clusters involved in cell cycle, and enrichment of immune tolerance regulating genes."
