Ways tomake your medical device available in the US market
Medical devices marketedin the US market are subject
to the regulatory controls ofthe Federal Food, Drug, and Cosmetic Act (FD&C
Act) and additionally the laws in Title 21 - Code of Federal laws (21 CFR)
elements 1-58, 800-1299. The regulatory controls and commerce pathwayshelp
assess the risk posed bythe device and are needed for assurance of safety and
effectiveness of the medical devices. The regulatory pathways include:
Premarket Notification (510(k)), Novo Classification Request, Exempt, Premarket
Approval (PMA), development Protocol (PDP), Humanitarian Use Exemption (HDE),
and Biologics License Application (BLA).
Broadly, the steps to bring a device to the market
can be covered in three steps:
1.
Classify the device
2.
Select the appropriate
regulatory pathway
3.
Establishment
registration and device listing
Classification of devices
The regulatory pathway for each device varies based
on the complexity of the device and the risk posed by the device. The US FDA
has a risk-based classification system for medical devices. Accordingly,
medical devices are classified as:
Ø Class I or low risk device
Ø Class II or medium risk device
Ø
Class III or high-risk
device
This classification of devices is made based on the
intended use and indications for use.
Selection of the regulatory pathway
There are different pathways available to medical
device manufacturers to place their devices in the US market.
510(k) Clearance (Pre-Market Notification)
Majority of the Class II devices and some of the
Class I devices are cleared for sale in the US via the pre-market notification
pathway. In a 510(k) submission, manufacturer is required to compile and submit
evidence demonstrating the safety and effectiveness of the proposed device by
proving substantial equivalence to a predicate device. Under the 510(k)-notification
pathway, predicate device is a legally marketed device already cleared by US
FDA for sale in the US. 510(k) dossier compilation includes documenting the
similarities and difference between the proposed device and the predicate
device. FDA takes anything between 30 and 90 days for processing a 510(k)
application.
Premarket Approval (PMA)
Class III devices generally are brought to the US
market via the pre-market approval pathway. Other devices with no predicate
device also general employ the PMA pathway. One of the highlights of the PMA
pathway is the need for good evidence proving safety and effectiveness of the
proposed device which is generally collated from a clinical trial. FDA
generally takes 180 days to process a PMA application.
De Novo Request
The De Novo pathway is good alternate for novel
device of significantly lower risk for which a suitable predicate may not be
available. However, manufacturer must ensure that the risks associated with the
proposed device between low to moderate and is adequately mitigated through
risk control. The typical turnaround time from FDA for De Novo is around 120
days.
Humanitarian Device Exemption (HDE)
A
Humanitarian Device Exemption pathway is applicable for devices that are
developed to treat or diagnose conditions that affects small or rare
populations -fewer than 4000 individuals in the US per year. FDA states that
for a device to be considered as a humanitarian use device, other comparable
devices with the same intended use must not be available on the market. US FDA
takes around 75 days to review the HDE application. The submission contents are
similar to that required for a PMA submission with the exception of data from
clinical investigations.
Custom Device Exemption (CDE)
Any device customized to meet the needs of a
specific patient will be subjected to the custom device exemption pathway. Such
devices are exempt from 510(k) or PMA submissions but must comply with other
requirements including:
·
Design Controls (21 CFR
Part 820)
·
Medical Device Reporting
(21 CFR Part 803)
·
Labeling (21 CFR Part
801)
·
Corrections and Removals
(21 CFR Part 806)
·
Registration and Listing
(21 CFR Part 807)
Other processes from US
FDA to enable regulatory planning for medical devices
Q-Submission process
US FDA enables discussions
with them to help manufacturers explore the different regulatory pathways
available to them for bringing their device to the market. The guidance for the
Q-submission program lists out the different way’s manufacturers can approach
US FDA for feedback or meetings with US FDA.
Investigational Device
Exemption (IDE) pathway
This pathway is for
medical device prototypes which are subjected to controlled studies to collect
clinical data to demonstrate safety and effectiveness.
Emergency Use
Authorization (EUA)
Emergency Use
Authorization may be initiated by US FDA to fulfil any emergency need as
determined by US FDA.
