The FDA is applying a good deal of resources toward a framework for regulation of artificial intelligence (AI) and machine learning (ML), but there are several sources of drag on those efforts. According to the FDA's Jana Delfino, one of these is that there is little agreement between regulators on a number of definitions, including the meaning of terms such as "validation," a problem she said must be solved if the field is to advance in a meaningful manner.

The FDA has granted breakthrough device designation to Endologix LLC for its Chimney Endovascular Aneurysm Sealing (ChEVAS) system. The device, which is intended for use in treating aortic aneurysms, is currently being evaluated in a multicenter pivotal study. The ChEVAS system is an endovascular abdominal aortic aneurysm (AAA) therapy designed to combine the Nellix 3.5 endograft with parallel visceral chimney stents to enable treatment of patients with juxtarenal, pararenal and suprarenal AAA.

Six weeks ahead of its PDUFA date, Kadmon Holdings Inc.’s NDA for Rezurock (belumosudil) has been approved to treat chronic graft-vs.-host disease. The selective oral inhibitor of Rho-associated coiled-coil kinase 2, a daily treatment for patients 12 and older after failure of at least two prior lines of systemic therapy, is the New York-based company’s first approved therapy.

Following the temporary lapse in FDA inspections of manufacturing sites amid the COVID-19 pandemic, this year has already seen more class I medical device recalls issued than in all of 2020. The agency is now working to remediate the interruptions resulting from the pandemic among certain manufacturers of high-risk medical devices in reporting these recalls to the FDA.

The COVID-19 pandemic brought in-person inspections of device manufacturing sites to a near halt, but that has left the agency with a significant backlog in these inspections. The FDA’s Associate Commissioner for Regulatory Affairs Judith McMeekin said recently that the FDA is intent on prodding Congress to provide the Office of Regulatory Affairs (ORA) with more monies, particularly given the meager increases in funding for oversight of the med-tech industry in the past few years.

Stryker Corp. has won the FDA’s nod for an implantable balloon spacer to aid in the healing of torn rotator cuffs. The de novo clearance of the Inspace subacromial tissue spacer system comes more than a decade after the biodegradable shoulder repair implant first debuted in European markets. The minimally invasive Inspace device is intended for arthroscopy treatment of massive irreparable rotator cuff tears (MIRCTs).

Negotiations between the FDA and industry over the next device user fee are going on behind closed doors, but the agency’s summaries of these meetings suggest there are sharp disagreements. While the FDA continues to press industry on additional fees for the total product life cycle advisory program, industry’s dissatisfaction with the FDA’s fiscal management of the user fee program has prompted a demand for a one-off audit of the agency’s use of those user fees.

The COVID-19 pandemic may have been largely responsible for the lower volume of enforcement activities against device makers in 2020, but the volume of these activities seems to be ramping up in 2021. Recently, the FDA posted a large batch of warning letters to device makers while the U.S. Department of Justice (DoJ) announced two new enforcement actions, including a $27 million fine to the operators of durable medical equipment distributorships for kickbacks, part of a growing set of signals that enforcement is back in vogue in the U.S.

TORONTO – Spino Modulation Inc., a subsidiary of Montreal-based med-tech company Spinologics Inc., has received breakthrough device designation for a vertebral body tethering (VBT) device to treat adolescent idiopathic scoliosis, one of three types of scoliosis that cause the spine to develop an abnormal curve.
