Fulgent Shares Data from Two Poster Presentations at SITC 2023 Annual Meeting

Fulgent Genetics, Inc. (NASDAQ: FLGT) (“Fulgent” or the “Company”), a technology-based company with a well-established clinical diagnostic business and a therapeutic development business, today announced data from two poster presentations being presented tomorrow, November 4, 2023, at the Society for Immunotherapy of Cancer (SITC) 38th Annual Meeting in San Diego, CA.

“These data support our mission to build a holistic platform to provide comprehensive solutions and services across the cancer care continuum, including early detection, diagnostics, and monitoring, as well as drug discovery and development,” said Ming Hsieh, Chairman and CEO of Fulgent Genetics and co-founder of Fulgent Therapeutics. “We see strong momentum in our precision diagnostics business as a driver of core revenue, and we are encouraged by the steady progress of our therapeutic development for FID-007 in oncology indications.”

The poster titled, “Critical clinical evaluation of plasma to tumor tissue concordance by cancer type using Illumina’s cell-free ctTSO500 commercial liquid biopsy assay,” explores the critical role of comparing ctDNA variants detected in plasma with those found in tissue, shedding light on the practical implementation of liquid biopsy technology. The research presents a meticulous analysis of plasma-to-tissue concordance across various cancer types, offering valuable insights into the considerations for validation, using Illumina's cutting-edge ctTSO500 commercial liquid biopsy assay. The clinical research findings, based on a comprehensive examination of 124 cases across different cancers, reveal significant concordance variations, often linked to the cancer stage and the timing of biopsy and blood sample collection. In uterine cancers, the researchers detected 65.9% of the SNV/indel variants in plasma that were also in FFPE, 47% in colon cancer, 67% in gastric cancer, 56% in bladder cancer, 51% in larynx cancer, and 41% in prostate. The study calls for the involvement of certified labs, highlighting the need for stringent quality management and regulatory alignment. The research ultimately underscores the reproducibility, sensitivity, and practical importance of Illumina's ctTSO500 liquid biopsy, particularly for patients who either cannot or prefer not to undergo traditional solid biopsies for cancer screening.
