ContaCT

Viz.AI

INDICATION FOR USE:

Notification-only, parallel workflow tool for use by hospital networks, trained clinicians to identify and communicate images of specific patients to a specialist, independent of standard of care workflow.

Uses an artificial intelligence (AI) algorithm to analyze images for findings suggestive of a prespecified clinical condition and to notify an appropriate medical specialist of these findings in parallel to standard of care image interpretation. Identification of suspected findings is not for diagnostic use beyond notification. Specifically, the device analyzes CT angiogram images of the brain acquired in the acute setting, and sends notifications to a neurovascular specialist that a suspected large vessel occlusion has been identified and recommends review of those images. Images can be previewed through mobile application.

Images that are previewed through the mobile application are compressed and are for informational purposes only and not intended for diagnostic use beyond notification. Notified clinicians are responsible for viewing non-compressed images on a diagnostic viewer and engaging in appropriate patient evaluation and relevant discussion with a treating physician before making care-related decisions or requests. ContaCT is limited to analysis of imaging data and should not be used in-lieu of full patient evaluation or relied upon to make or confirm diagnosis.

ADDRESSING UNMET NEED:

  • First approved Clinical Decision Software to analyze computed tomography (CT) results that may notify providers of stroke potential
  • 795,000 in U.S. have stroke each year; causes serious and irreversible damage
  • Software device notifies specialist earlier thereby decreasing the time to treatment

DEVICE DESCRIPTION:

  • Computer-aided triage software using AI algorithm to analyze images for stroke indicators
  • Designed to analyze brain CT images
  • Send text notification to neurovascular specialist if suspected large vessel blockage
  • Involve specialist sooner with algorithm automatically notifying specialist concurrently with first-line provider who is conducting standard review of images
  • Specialist still needs to review images on clinical workstation

ALGORITHM & NOTIFICATION PERFORMANCE:

  • Retrospective study of 300 CT images
  • Brain large vessel blockage detection: Algorithm image analysis and notification vs.  performance of two trained neuro-radiologists

CaptureBANYAN Brain Trauma Indicator

Banyan Biomarkers, Inc.

INDICATION FOR USE:

In vitro diagnostic chemiluminescent enzyme-linked immunosorbent assay (ELISA). Assay provides semi-quantitative measurement of the concentrations of ubiquitin Cterminal hydrolase-L1 (UCH-L1) and glial fibrillary acidic protein (GFAP) in human serum, and is used with the Synergy 2 Multi-mode Reader.

The assay results obtained from serum collected within 12 hours of suspected head injury are used, along with other available clinical information, to aid in the evaluation of patients 18 years of age and older with suspected traumatic brain injury (TBI, Glasgow Coma Scale score 13-15). A negative assay result is associated with the absence of acute intracranial lesions visualized on a head CT (computed tomography) scan.

Capture.JPGAPTIMA HBV Quant Assay

Hologic, Inc

INDICATION FOR USE: 

In vitro nucleic acid amplification test for the quantitation of hepatitis B virus (HBV) DNA in human plasma and serum on the fully automated Panther® system.

Plasma may be prepared in ethylenediaminetetraacetic acid (EDTA), anticoagulant citrate dextrose (ACD) solution, and plasma preparation tubes (PPTs). Serum may be prepared in serum tubes and serum separator tubes (SSTs). Specimens are tested using the fully automated Panther system for sample processing, amplification, and quantitation. Specimens containing HBV genotypes A, B, C, D, E, F, G, and H are validated for quantitation in the assay.

The Aptima HBV Quant assay is intended for use as an aid in the management of patients with chronic HBV infections undergoing HBV antiviral drug therapy. The assay can be used to measure HBV DNA levels at baseline and during treatment to aid in assessing viral response to treatment. The results from the Aptima HBV Quant assay must be interpreted within the context of all relevant clinical and laboratory findings. Assay performance for determining the clinical stage of HBV infection has not been established. Clinical performance characteristics have been established for individuals treated with tenofovir disoproxil fumarate or entecavir.

The Aptima HBV Quant assay is not approved for use as a screening test for the presence of HBV DNA in blood or blood products or as a diagnostic test to confirm the presence of HBV infection

ADDRESSING UNMET NEED: 

  • Hepatitis B is a liver infection caused by HBV; transmitted through infected blood, semen, or other body fluid
  • Risk for chronic infection is related to age at infection: ~ 90% of infected infants become chronically infected, vs. 2%–6% of adults
  • Chronic Hepatitis B infection can lead to cirrhosis or liver cancer

DESCRIPTION:

  • In vitro nucleic acid amplification test with real time transcription-mediated amplification (TMA) technology on Panther system
  • Standardized to the 3rd WHO International Standard for Hepatitis B Virus
  • Three main steps which all take place in a single tube on the Panther system: (1) target capture, (2) target amplification by TMA, (3) detection of amplification products (amplicon) by fluorescent labeled probes

EFFECTIVENESS AND SAFETY: 

  •  Effectiveness demonstrated when used for the quantitation of HBV DNA in human plasma and serum and serum separation tubes for management of patients undergoing treatment.
  • Clinical performance evaluated in ethnically diverse population representative of intended use population
  • Accurately measures viral load in patient at baseline and at intervals during antiviral therapy
  • Should benefit physician and patients in management of chronic HBV infected individuals undergoing antiviral therapy when used according to the directions for use in labeling

REGULATORY PATHWAY: PMA

  • Product Code: MKT

REIMBURSEMENT

  • CMS has determined that screening for HBV infection  is reasonable and necessary for the prevention or early detection
