Abbott Laboratories received FDA approval for its Amplatzer Amulet left atrial appendage occluder to treat people with atrial fibrillation who are at risk of ischemic stroke about a month earlier than generally expected, given the backlog at the FDA. The dual-closure device closes the left atrial appendage during the procedure, reducing the risk of blood clots immediately and eliminating the need for blood thinners both during the healing process and longer term.

The FDA’s quarterly report on device user fee performance goals encodes a number of metrics, such as the rate at which PMA originals are cited for a major deficiency on the first review cycle. For premarket approval applications (PMAs) filed in fiscal year 2021 to date, the major deficiency rate on the first cycle is 86%, which would be tied for the fifth highest rate in two decades if that rate holds throughout the balance of the fiscal year.

The FDA has given a green light to Foundation Medicine Inc.’s Foundationone CDx as a companion diagnostic for Takeda Pharmaceutical Co. Ltd.’s Alunbrig to identify patients with anaplastic lymphoma kinase (ALK)-positive metastatic non-small-cell lung cancer (NSCLC). The approval comes as Laboratory Corp. of America Holdings (Labcorp) is launching a companion diagnostic to identify NSCLC patients with the KRAS mutation. NSCLC accounts for about 85% of all lung cancers, with an estimated 1.8 million new cases diagnosed each year worldwide. Of those, 3% to 5% carry the ALK gene mutation, which is often missed with standard testing methods.

There is “a wide gap” in the availability of pediatric medical devices that suggest most of these were developed for adolescents, according to a new study on FDA premarket approval applications (PMAs). The findings stem from an evaluation of 297 PMA documents for 149 high-risk devices, 68% of which include pediatric age indications. Pediatric medical devices have lagged behind their adult counterparts in terms of availability, options and innovation. The new findings add to the current relatively limited body of research considering the ample medical device space but are consistent with previous findings that most devices indicated for children are limited to those over 18 years of age.

Medtronic plc snagged FDA premarket approval for its recharge-free implantable neurostimulator (INS), Vanta, for patients with intractable pain. The spinal cord stimulator offers up to 11 years of device life, with optimal programming. That represents a 10% improvement on the Dublin-based company’s previous longest-lasting INS, Primeadvanced, and a near doubling of device life compared to Abbott Laboratories’ Proclaim and Boston Scientific Corp.’s Wavewriter Alpha, using the settings recommended in the clinician manuals.

Boston Scientific Corp.'s Therasphere Y-90 glass microspheres received a PMA for treatment of patients with unresectable hepatocellular carcinoma (HCC). The radioembolization technique has been used in more than 70,000 patients under a humanitarian device exemption over the last 20 years. The U.K.'s NICE also recently recommended Therasphere for treatment of patients with HCC.

A U.S. FDA advisory committee voted 14 nays to three ayes that the benefits of the Lutonix 014 drug-coated balloon (DCB) do not outweigh the risks in a panel proceeding peppered by problems with missing data and a lack of operator blinding. The panel widely saw the use of paclitaxel-eluting technologies in other areas of the vasculature as a reassurance that this device might perform as promised, but the outcome nonetheless leaves the sponsor with a new round of negotiations with the FDA as to how to move forward.

Shockwave Medical Inc. said Tuesday that its intravascular lithotripsy (IVL) therapy has won U.S. FDA approval for the treatment of severe coronary artery disease (CAD). The technology, which was granted breakthrough device designation in 2019, is a novel application of lithotripsy, which has long been used to safely shatter kidney stones.
