Companies slapped with warnings for unapproved weight-loss drugs

Feb. 14, 2024
By Mari Serebrov
The demand for semaglutide, a GLP-1 drug, and other popular prescription weight-loss drugs is adding to the U.S. FDA’s regulatory load as more and more companies are offering unapproved knockoffs of the products directly to consumers. The FDA posted two warning letters Feb. 13 – to Miami-based US Chem Labs and a New-York company, Synthetix Inc. doing business as Helix Chemical Supply – citing the companies for misbranding unapproved semaglutide and tirzepatide, also a GLP-1 drug, by marketing them on the Internet, along with claims about their therapeutic benefits.

Abiomed stung by FDA’s final guidance for clinical decision support in warning letter

Oct. 11, 2023
By Mark McCarty
The U.S. FDA’s final guidance for clinical decision support (CDS) systems may be the subject of two citizen’s petitions requesting the agency scrap the guidance and start over, but that doesn’t mean the agency is not enforcing the terms of the guidance. Danvers, Mass.-based Abiomed Inc., took in a Sept. 19 warning letter stating that the company’s Impella Connect system qualifies as a CDS product because it provides “patient-specific medical information to detect a life-threatening condition,” an interpretation that is sure to intensify the larger debate about whether the CDS final guidance is an extra-statutory exercise in regulatory engineering.

July 20, 2023
By Mark McCarty
U.S. FDA warning letters to device makers seemed to be on pause for a couple of years, but the agency is picking up the pace with two warnings posted July 18. Outset Medical Inc., of San Jose, Calif., was previously known to be the recipient of a warning letter, but Edge Biologicals Inc. of Memphis, Tenn., took in a warning letter that is replete with repeat violations disclosed in 2015 and 2018, as well as a warning letter issued 11 years ago.

Maker of orthodontic planning software snares FDA warning for software validation lapse

June 28, 2023
By Mark McCarty
Makers of dental equipment don’t typically show up on the U.S. FDA enforcement radar screen, but the introduction of biologics and software into routine dental practice has upped the regulatory stakes. This can be seen in the June 20, 2023, warning to Vitang Technology LLC, of Tustin, Calif., which cited the company for failure to validate a change of software used in orthodontic treatment planning systems, but the FDA reinforced the notion that claiming that the agency approved or cleared the device is also a violation of the Code of Federal Regulations.
