• NeXT Dx helps clinicians make informed, personalized cancer treatment selections and match patients with clinical trials
• Access to NeXT Dx expands to the 66 million Medicare and Medicare Advantage beneficiaries

FREMONT, Calif. / Jan 16, 2024 / Business Wire / Personalis, Inc. (Nasdaq: PSNL), a leader in advanced genomics for precision oncology, today announced it has received a final Medicare coverage determination for its NeXT Dx ultra-comprehensive tumor genomic profiling assay, providing access for the nation’s 66 million Medicare and Medicare Advantage beneficiaries.

Matching patients to their optimal cancer therapy requires a testing platform that can accurately report a broader range of clinically actionable genomic alterations. NeXT Dx analyzes a tumor’s entire exome (DNA) and transcriptome (RNA) to uncover deeper insights into therapy selection, including RNA-based fusions and advanced biomarkers that smaller panels might miss, such as tumor mutational burden (TMB) and microsatellite instability (MSI). In addition, NeXT Dx utilizes paired tumor and non-tumor samples to report more accurate results.

Coverage for NeXT DX was extended effective August 29, 2023, under the Palmetto GBA MolDx program foundational Local Coverage Determination (LCD) L38119 (“Next-Generation Sequencing for Solid Tumors”). Personalis estimates that approximately half of new solid tumor cancer cases will be diagnosed in patients covered by Medicare.

“We are thrilled to receive our first coverage determination with our ultra-comprehensive NeXT Dx test, which offers treating physicians a better chance of finding an FDA-approved therapy or clinical trial for patients with advanced cancer,” said Chris Hall, President and Chief Executive Officer at Personalis. “With our recent early access launch of the ultra-sensitive NeXT Personal Dx test, which is designed to detect molecular residual disease and cancer recurrence, we continue our momentum in offering products that provide deep genomic insights throughout a cancer patient’s entire journey.”
