Central Nervous System Infection Clinical Trial in Baltimore, MD

About This Central Nervous System Infection Study in Baltimore

Delve Bio, Inc. is a developer of novel mNGS tests with the goal of aiding in the diagnosis of infectious diseases in several clinical indications that may not have alternative traditional diagnostic methods routinely available. A proof of concept for the clinical utility of this mNGS testing methodology has been described in several seminal publications.1,2,3,4 Delve Bio is currently offering one of these assays as a laboratory-developed test (LDT) performed in a CLIA-certified, CAP-accredited laboratory. The test is called Delve Detect CSF. Delve Detect CSF is an mNGS in vitro diagnostic test intended for the simultaneous detection and differentiation of nucleic acids from multiple bacteria, viruses, fungi, and parasites in CSF from individuals suspected of meningitis or encephalitis. Delve Detect CSF identifies microbial nucleic acid in an unbiased and pathogen-agnostic manner. Historically, due to its cost and turnaround times, which can be on the order of 14 days, CSF mNGS testing is typically employed as a "test of last resort" for patients with suspected infectious meningitis and encephalitis, and is often used when traditional diagnostic methods cannot identify the cause of infection. In the IMPACT Study, we seek to investigate the diagnostic and clinical utility of mNGS testing if it is employed earlier in the diagnostic workup of patients with suspected CNS infection and unknown etiology in conjunction with a more rapid turnaround time for test results on the order of two business days from sample receipt by the laboratory. Participants who meet the inclusion/exclusion criteria and undergo informed consent (and assent as applicable) will be enrolled in the study, assigned to the appropriate subpopulation category, and obtain CSF testing with Delve Detect CSF in addition to other SOC testing. In addition to the Delve Detect CSF test results, associated clinical information and health economic data for the participants will be obtained through chart abstraction. Clinical information will be de-identified wherever possible, and any PHI being collected will not be individually reported as part of the intended analysis. The site investigator or their designee at each site will complete a survey to provide a consensus view of the treatment team regarding how the availability of Delve Detect CSF test results in early diagnostic workup affected clinical decision-making. Analyses of the test results from Delve Detect CSF and other SOC diagnostic methods, in addition to the clinical information, will not be used to identify any participant. Information generated through the study will be recorded in such a manner that the identity of the human participants cannot readily be ascertained directly or through identifiers linked to the participants, and the participants will not be contacted. The results from this study could be used to support publications in scientific white papers, manuscripts, posters, and/or presentations.
