On February 1, 2024 DELFI Diagnostics, Inc., a developer of accessible blood-based tests that deliver a new way to enhance cancer detection, reported availability of the company’s fragmentome-based research use only (RUO) cancer monitoring assay (Press release, Delfi Diagnostics, FEB 1, 2024, View Source [SID1234639805]). The DELFI-Tumor Fraction (DELFI-TF) assay is a highly sensitive, inexpensive means of noninvasive measurement of tumor burden and assessing treatment response and resistance in patients with advanced cancer.

Additionally, DELFI announced a new research collaboration with Immunocore Holdings plc (Nasdaq: IMCR) – a commercial-stage biotechnology company pioneering the development of a novel class of bispecific T cell receptor (TCR) immunotherapies against cancer (ImmTAC molecules) – focused on exploring the use of the DELFI-TF cancer monitoring assay as an early predictor of benefit from treatment with ImmTAC-based therapies.
"The DELFI-TF assay delivers a genome-wide measure of the proportion of cfDNA derived from a tumor and it is highly correlated with the mutant allele fraction (MAF) that is often used to evaluate treatment response and resistance to immunotherapies in advanced cancer patients. Our fragmentome-based assay has numerous advantages as it requires very little plasma, has a low cost of processing, and is not confounded by clonal hematopoiesis or driver mutation switches," said Nicholas C. Dracopoli, Ph.D., co-founder and Chief Scientific Officer of DELFI. "We are excited that Immunocore will be further exploring the clinical and research potential of the DELFI liquid biopsy platform as a new approach to monitoring treatment response."
The DELFI-TF RUO assay is also being evaluated by additional parties across the pharmaceutical industry for its potential application in advancing other healthcare discoveries, and DELFI anticipates announcing more research collaborations in the near term.
