IntegraGen SA announced the publication of the results of a definitive study reporting on the analysis of the expression of miR-31-3p in tumors from 370 RAS wild-type (WT) metastatic colorectal cancer (mCRC) patients enrolled in the FIRE-3 clinical trial (AIO KRK-0306). The study found that a low expression of the miR-31-3p biomarker predicts both improved survival and treatment response in patients receiving anti-EGFR therapy. In addition to confirming miR-31-3p is predictive of outcomes for RAS WT mCRC patients treated with anti-EGFR therapy, the study also found that patients with a miR-31-3p expression below a pre-defined threshold have a one year longer median overall survival, a 40% reduction in mortality risk, and a better treatment response when they are treated with FOLFIRI plus cetuximab compared to FOLFIRI plus bevacizumab. Conversely, no difference in outcomes was seen between the two treatment groups in patients with miR-31-3p expression above the pre-defined threshold. These results support the use of miR-31-3p expression testing in primary tumors from RAS WT mCRC patients to assist clinicians to identify the most appropriate first line biologic therapy may be most beneficial. IntegraGen will presenting new data reporting positive results from an analysis of miR-31-3p expression in over 1,400 resected stage III colon cancer patients enrolled in the PETACC-8 trial during the upcoming 2018 Annual Meeting of the European Society for Medical OncologyOctober 19-23 in Munich, Germany. IntegraGen has commercialized the miRpredX 31-3p kit, a proprietary IVD CE Marked kit and has also licensed its intellectual property associated with miR-31-3p to GoPath Laboratories for the North American market. The FIRE-3 (AIO KRK-0306) clinical trial is an independent, randomized, controlled Phase III trial conducted in Europe and led by University Hospital, LMU Munich, Germany. The study compares outcomes of KRAS Exon 2 wild-type (WT) stage IV colorectal cancer patients randomized to receive FOLFIRI therapy (5-FU, folinic acid and irinotecan) in combination with either cetuximab or bevacizumab.
