FREMONT, Calif. / May 22, 2024 / Business Wire / Personalis, Inc. (Nasdaq: PSNL), a leader in advanced genomics for precision oncology, announced today that two podium presentations and multiple posters featuring data for the company’s NeXT Personal^® whole genome-based, tumor-informed assay for ultra-sensitive ctDNA detection will be presented at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting, which convenes from May 31-June 4, 2024, in Chicago, Illinois.

“As the body of studies continues to grow that demonstrates the role our ultra-sensitive MRD test, NeXT Personal, can play in identifying recurrent cancer early, we were honored to learn that two Personalis studies were selected as podium presentations at ASCO 2024’s Clinical Science Symposium”, said Dr. Richard Chen, Chief Medical Officer and Executive Vice President, R&D at Personalis.

The two studies that were selected to appear as podium presentations are:
