FDA Breakthrough Status for Resolution Bioscience Assay
FDA has granted Resolution Bioscience a Breakthrough Device Designation for the Resolution HRD liquid biopsy assay, a qualitative in vitro diagnostic to detect sequence variations in key genes related to homologous recombination deficiency for single nucleotide variants, indels, and copy number variants. The company says it plans to seek device approval and it would be the “first assay to detect gene deletions from cell-free DNA (cfDNA) and differentiate between single copy and biallelic (homozygous) gene deletions through a simple blood draw.” The assay would also detect biallelic loss of function through a combination of a deleterious mutation and a heterozygous deletion in the same gene, it says.
