FDA Medical Device Controversies - Approvals and Clearance

I thoroughly enjoyed reading this Health News Digest article, Is That Medical Device Safe And Effective? Who Knows? It's a great overview of:
  • medical device classification
  • premarket approval (PMA)
  • premarket notification (510(k))
  • substantially equivalent
  • anecdotes that highlight controversies in the items above. This is the best part of the article.

For me, I get the sense that it's generally about business, and that some unethical companies might be putting our collective safety at risk.

The Food and Drug Administration (FDA) has determined that ZOMETA (zoledronic acid for injection), equivalent to (EQ) 4 milligrams (mg) base/vial, lyophilized powder for injection, was not withdrawn from sale for reasons of safety or effectiveness. This determination will allow FDA to approve abbreviated new drug applications (ANDAs) for zoledronic acid lyophilized powder for injection, 4-mg base/vial. The Federal Register published the FDA docket "Determination That ZOMETA (Zoledronic Acid for Injection), Equivalent to 4 Milligrams Base Per Vial, Lyophilized Powder for Injection, Was Not Withdrawn From Sale for Reasons of Safety or Effectiveness (pdf)."

According to IP Pharma Doc's post, Zoledronic acid (ZOMETA) lyophilized powder for injection: USFDA confirmed that drug was not withdrawn due to safety issues, this decision will allow US FDA to approve ANDA's for the innovator's (Novartis) discontinued product (in May, 2003).

Medical Devices Containing Antimicrobial Agents - FDA Guidance Pending

Updated October 22, 2020

Draft Guidance for Industry and FDA Staff - Premarket Notification [510(k)] Submissions for Medical Devices that Include Antimicrobial Agents (withdrawn 08/03/2018)

- -  original post follows below  - -

Here's a late-breaking scoop from FDA Legislative Watch, "FDA Finalizing Guidance For Devices Containing Antimicrobial Agents." Reportedly, revisions to a draft guidance on 510(k) submissions for devices or combination products that incorporate antimicrobial agents are awaiting final sign-off at the FDA. Apparently, one of the biggest issues for debate is whether a device is substantially equivalent to a marketed product with the same design, or whether it is a modification. Bottomline, modified devices require much more data.
