Genomic testing firm Veracyte Inc. is eyeing 2021 for the launch of its noninvasive nasal swab classifier for early lung cancer detection and diagnosis, following preliminary clinical data demonstrating high sensitivity in low-risk patients and high specificity in high-risk patients with known lung nodules. The South San Francisco-based company is developing the nasal swab test in collaboration with Johnson & Johnson Inc.'s Lung Cancer Initiative, part of a long-term strategic collaboration that also aims to speed commercialization of Veracyte's Percepta genomic sequencing classifier.
