Background: Many patients with non-small cell lung cancer (NSCLC) lack access to highly effective approved targeted therapeutics due to multiple gaps in biomarker testing. Challenges in comprehensive molecular testing include complexities associated with the need to assess the presence of multiple variants, costs of running multiple sequential assays per sample, high assay quality control (QC) failure rates, clinical need for rapid turn-around time (TAT) to initiate therapy, and insufficient tissue samples. The ASPYRE-Lung NSCLC assay addresses gaps in multiplexed testing by simultaneously analyzing DNA and RNA, detecting 114 actionable genomic variants across 11 genes, consistent with current NSCLC treatment guidelines.

Selective estrogen receptor modulators (SERM) act as antagonists in specific tissues and tamoxifen, a SERM, has served as a drug for decades for ERα-positive breast cancers. However, the ligand-selective and tissue-specific response of ERα biological activity and the resistance to tamoxifen treatment in advanced stages of ERα-positive breast cancers underscores the need to find a ligand-independent inhibitor for ERα.
