Tatanka! • A Lot of devil in details • Many higher concepts aligned • Need to agree on terms and
definitions; speak same language
Observations
• WE NEED YOUR HELP • Stakeholders need to be active
participants: listen, communicate, consider alternatives
• What is equitable, rational, efficient regulation?
• What’s the best system for patients?

Why Regulatory Reform (LDT)? Necessary
• Regulations are antiquated • Diagnostics ≠ devices • It does not make sense to
compare to predicates • System does not adapt well to
rapidly evolving technology • Submission requirements for
modifications to tests can be burdensome and costly.
• No efficient or timely mechanism to reclassify tests
• Biforcated regulatory path for the same thing doesn’t make sense.
Nuisance • Existing regulations work • Already compare to known
specimens, reference standards, reference methods
• Need flexibility to modify assays as new scientific information becomes available
• Already subject to multiple regulations, inspections
• Medical services outside of FDA authority
• Developed and performed under supervision of qualified laboratory director

Diagnostic Test Working Group • Coalition of a few manufacturers and laboratories met end
of 2014 and developed a proposal for fundamental regulatory reform
• Began sharing publically in mid-February • Early March began outreach with AdvaMed, ACLA, E&C and
FDA • Group expanded late March; more aggressive outreach to
other stakeholders through April • In constant contact with FDA, and other stakeholders on
clarifying language • Legislative language expected sometime in June • Legislative vehicle?
• 21st Century Cures (2015?) • MDUFA (2016)

DTWG Proposal in a nutshell • Proposal applies to all IVCT • Allocates responsibility (like activities):
• Test design/development/procedure – FDA • Laboratory operations – CMS • Interpretation/consultation – states
• Classification: high, moderate, low risk proposed by developer; FDA 60 day option to reject
• IVCT moves high-low risk as becomes established • Standard for review: “reasonable assurance of
analytical and clinical validity” established through “competent and reliable evidence”

DTWG Proposal in a nutshell • Special pathways for rare disease, emergency
use and unmet needs tests • Post-market QS and recalls similar to current
paradigm, AER tailored to tests • Instrument platforms Low Risk • Incentive vouchers for development innovative
IVCT • 3-4 year transition to new system

Big Bucket Issues • Definitions, e.g., “well-established” • What is the diagnostic? • Standard for review: S&E vs A&C V • Risk Classification process: levels of evidence • Submissions: what evidence • Modifications • QSR/CLIA for production • New Center for Diagnostics?

How is this different than status quo? • Recognizes diagnostics as fundamentally different from devices
– Provides information; are not therapeutic/interventional – Medical professional applies the intervention
• New Center? • No arbitrary classification
– Use existing evidence to identify data gaps as a means to submission • No more predicate device • Give FDA more flexibility for adapting to new evolving technologies and
modifications (while protecting developers) – Balance pre- post-market submissions and in-house data
• Recognizes that laboratory operations are different from manufacturing operations
• Binding (guidances are not)
