Sourcing assay validation samples as positive run controls or workflow controls in targeted NGS RNA fusion assays remains a challenge today. This is further exacerbated with clinical labs looking to provide validated NGS assays for patient stratification in a host of new drugs in clinical trials or newly approved targeting fusion genes, such as NTRK genes (Larotrectinib, Loxo/Bayer) and Entrectinib (Genentech/Roche) for rare cancers in adult and pediatric patients, and RET (Loxo/Lilly) for lung cancer. SeraCare produces several RNA fusion reference materials. This article describes the development and multi-laboratory evaluation of a pan-cancer multiplexed Fusion RNA reference standard for analysis of clinically relevant fusion genes in solid tumors. The evaluation was conducted at 5 different laboratories on different NGS platforms (amplicon- and hybridization capture-based) as well as at different RNA inputs within a platform. Results highlight the utility of this Fusion RNA reference material to support clinical NGS assays as positive controls in solid tumor cancer patient stratification for many of these fusion-based targeted therapies.
