  • Ensure they were available using Emergency Use Authorization (EUA)

Two primary blood diagnostic tests

  • Nucleic acid tests: Identify infection by confirming  virus’ RNA
  • Serological tests: Identify antibodies produced by body’s immune system upon Zika detection
  • Development of tests challenging because Zika antibodies produced by the body difficult to differentiate from other related virus antibodies (dengue, West Nile)

FDA’s sample panel

  • Plasma samples from individuals infected with Zika, West Nile, or dengue
  • Diagnostic developers use to check if test can distinguish Zika vs. others
  • Also use to compare test vs. other Zika tests approved via EUA
  • Available to developers who have interacted with the FDA through the pre-EUA process and have devices in final stages of validation

QuantX

Quantitative Insights, Inc

INDICATION FOR USE:

Computer-aided diagnosis (CADx) software device used to assist radiologists in the assessment and characterization of breast abnormalities using MR image data. The software automatically registers images, and segments and analyzes user-selected regions of interest (ROI). QuantX extracts image data from the ROI to provide volumetric analysis and computer analytics based on morphological and enhancement characteristics. These imaging (or radiomic) features are then synthesized by an artificial intelligence algorithm into a single value, the QI score, which is analyzed relative to a database of reference abnormalities with known ground truth.

QuantX is indicated for evaluation of patients presenting for high-risk screening, diagnostic imaging workup, or evaluation of extent of known disease. Extent of known disease refers to both the assessment of the boundary of a particular abnormality as well as the assessment of the total disease burden in a particular patient. In cases where multiple abnormalities are present, QuantX can be used to assess each abnormality independently.

This device provides information that may be useful in the characterization of breast abnormalities during image interpretation. For the QI score and component radiomic features, the QuantX device provides comparative analysis to lesions with known outcomes using an image atlas and histogram display format.

QuantX may also be used as an image viewer of multi-modality digital images, including ultrasound and mammography. The software also includes tools that allow  users to measure and document images, and output in a structured report.

Limitations: QuantX is not intended for primary interpretation of digital mammography images.

REG PATHWAY: De Novo request

  • Regulation Number: 21 CFR 892.2060
  • Regulation Name: Radiological computer-assisted diagnostic (CADx) software for lesions suspicious for cancer
  • Regulatory Class: Class II

  •  image processing device intended to aid in the characterization of lesions as suspicious for cancer identified on acquired medical images such as magnetic resonance, mammography, radiography, or computed tomography
  • characterizes lesions based on features or information extracted from the images and provides information about the lesion(s) to the user
  • diagnostic and patient management decisions are made by the clinical user

IDENTIFIED RISKS:

  • Incorrect lesion(s) characterization leading to false positive results
  • Incorrect lesion(s) characterization leading to false negative results
  • Misused to analyze images from an unintended patient population or on images acquired with incompatible imaging hardware

Opening Remarks by Dr. Gottlieb for Public Meeting on Generic Drug Competition

FDA doesn’t have a direct role in how drugs are priced but play a  role in the eventual cost of medicines

  • impact on cost of drug development
  • impact on drug pricing
  • cost of scientific and regulatory risk, time for development and approval, failures
  • can impact drug costs by encouraging competition with focus on generic drugs

Concern with branded companies “gaming” FDA system

  • taking advantage of rules to deliberately forestall generic entry
  • making it hard for generic drug makers to purchase branded drug  for testing
  • raising scientific objections timed to delay approval of ANDA
  • gratuitous price increases on niche products

FDA wants to hear from the public

  • ways to benefiting consumers
  • ways to balance access and innovation
  • market-based incentives to attract entrepreneurship to support new innovation

FDA undertaken “Drug Competition Action Plan” with 3 major elements

  • Identify sources of ‘gaming’ and change rules e.g. REMS
  • Identify scientific and regulatory obstacles to generic entry of generic medicines e.g. improve regulatory framework
  • Focus on the efficiency and throughput of overall generic drug program e.g. review efficiencies, improve scientific knowledge, enhance communication

GDUFA II proposal, currently pending before Congress

  • designed to reduce the number of ANDA review cycles
  • expand frequency and scope of communications between FDA and ANDA filers,  more opportunities to cure deficiencies,  get quick approvals
  • create pre-ANDA program, with a special focus on complex generics
  • issue “Good ANDA Assessment Practices” MAPP for internal policies
  • issue  “Good ANDA Submission Practices” guidance

FDA News: Biomarker for Acute Pancreatic Injury, Innovation Initiative and Cures Act, Nail Care Products

FDA BRIEF: Week of July 3, 2017


Spotlight on CDER Science

Lab Tests in Rodents Suggest Potential New Biomarker for Acute Pancreatic Injury

Biomarkers are measurable indicators that can signify presence/severity of disease 

  • FDA prioritizes identification of new, reliable and sensitive biomarkers

Acute pancreatic injury requires sensitive biomarkers

  • Numerous drugs, including those to treat type-2 diabetes, linked to pancreatic injury
  • Not evident in pre-approval, non-clinical safety and clinical trials with traditional pancreatic injury biomarkers, serum amylase and lipase
  • Thus more sensitive and specific biomarkers required to detect /monitor pancreatic injury potential of new drugs

Division of Applied Regulatory Science research suggest microRNAs (miRNAs) may be good biomarker candidates

  • Have a key role in the regulation of genes by repressing gene expression
  • Can increase rapidly after tissue injury
  • miR-216a, miR-217, miR-216b, miR-375, miR-148a able to detect pancreatic injury earlier and were more specific to pancreatic injury in rats and mice. These miRNAs also found in humans.
  • Additional data needed to determine utility in patients
