Breakthrough Insights on Personalis NeXT Personal MRD Test

Personalis NeXT Personal MRD Test Shows Promising Results

FREMONT, Calif. — Personalis, Inc. (Nasdaq: PSNL), renowned for its advanced capabilities in MRD testing, has unveiled findings at a prestigious medical congress. These findings underscore the significant role of the NeXT Personal assay, designed to identify and monitor minimal residual disease (MRD) in cancer patients. By detecting tiny amounts of circulating tumor DNA (ctDNA) in the blood, this innovative test offers a new avenue for comprehensive cancer care. Launched in late 2023, the NeXT Personal MRD test is making waves in the oncology community, highlighting its potential to transform patient management.

Key Highlights from the Recent Studies

At the European Society of Medical Oncology Congress, groundbreaking research was presented, showcasing the utility of the NeXT Personal assay in monitoring lung cancer and enhancing treatment strategies for patients undergoing immunotherapy. The studies emphasize how sensitive MRD assays can significantly impact cancer management.

Comprehensive Analysis of Lung Cancer Patients

In a detailed study led by Professor Charles Swanton and his team at prominent research institutions, over 400 non-small cell lung cancer (NSCLC) patients were analyzed using the NeXT Personal assay. This research represents one of the largest MRD studies conducted in the realm of lung cancer. The findings not only build on initial data presented at previous medical congresses but also illuminate key detection aspects that contribute to better patient outcomes.

• Robust detection rates for residual lung cancer during the critical first 120 days post-surgery.
• Approximately 42% of notable detections occur within the ultrasensitive range (less than 80 ppm), demonstrating the NeXT Personal's capabilities.
• Pre-operative ctDNA detection serves as a reliable predictor of clinical outcomes in lung adenocarcinoma.
• Ongoing dynamic monitoring through adjuvant therapy positions the NeXT Personal assay as a pivotal tool for assessing patient risk and tailoring treatment pathways.

These findings indicate NeXT Personal's high sensitivity in detecting early-stage lung cancer recurrence, with significant lead times ahead of traditional imaging techniques. The ability to stratify patients based on recurrence risk helps personalize treatment strategies and improve overall prognoses.

Insights into Immunotherapy Response

The second study presented by Dr. Rodrigo Toledo at the Vall d'Hebron Institute of Oncology (VHIO) provided compelling evidence regarding late-stage cancer patients undergoing immunotherapy. Involving over 200 subjects, this extensive cohort analysis utilized the NeXT Personal assay to highlight significant trends in ctDNA levels.

The research revealed that patients exhibiting marked reductions in ctDNA levels in response to immunotherapy experienced substantially longer overall survival rates compared to those without such decreases. This pivotal insight points to the assay's potential as a monitoring tool for gauging therapeutic efficacy and patient outcomes.

Commentary from Personalis Leadership

Richard Chen, Chief Medical Officer at Personalis, remarked on the significance of the studies: “The expanded data from the TRACERx and VHIO studies showcase the robust performance and clinical relevance of our NeXT Personal MRD test. We are proud to have demonstrated a critical role for an ultra-sensitive MRD approach to identify patients at risk of recurrence, monitor therapy responses, and facilitate earlier detection of cancer recurrence.”
