PERTH, Australia – Digital cognitive assessment technology company Cogstate Ltd. saw its stock skyrocket 60% on the heels of FDA accelerated approval of Biogen Inc./Eisai Co. Ltd.’s Alzheimer’s disease drug Aduhelm (aducanumab). Cogstate and Eisai signed a deal in October 2020 that granted Eisai global development rights and exclusive commercialization rights of all cognitive function tests developed by Cogstate.

Livanova plc has launched an IDE trial of its Aura6000 sleep apnea device, following approval by the FDA to proceed with the study. The implantable pulse generator (IPG) is designed to treat patients with moderate to severe obstructive sleep apnea (OSA) who do not get relief from a traditional continuous positive airway pressure (CPAP) machine or refuse to use one.

With paralysis affecting more than 5 million Americans, devices that serve as brain-computer interfaces (BCIs) are increasingly important, even if few are commercially available. The FDA has responded to the predicament with a leapfrog guidance, a preliminary form of guidance designed to foster more interaction with industry and encourage developers to move along on development programs for devices that will aid patients in restoring lost motor and/or sensory capabilities.

LONDON – Controversy over the quality of the data supporting approval of Biogen Inc.’s Aduhelm (aducanumab), and FDA’s requirement for a phase IV study to demonstrate real-world evidence of the effectiveness of the drug, has put the spotlight on the need for better dementia diagnostics, both to stratify trials and to track any reduction in clinical decline.

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.

Developers of blood tests for the early diagnosis of Alzheimer’s disease (AD) are poised to see a spike in demand, following the FDA’s accelerated approval on Tuesday of Cambridge, Mass.-based Biogen Inc.’s AD drug treatment Aduhelm (aducanumab). The FDA’s decision paves the way for AD assays to move beyond aiding in drug development toward addressing ongoing issues with undiagnosed cases.

Cymedica Orthopedics Inc. received FDA clearance for its Intellihab system to reduce pain associated with osteoarthritis in the knee. The system uses neuromuscular electrical stimulation to strengthen muscles supporting the knee without requiring typical exercises such as squats that could increase pain and further degrade the joint. Intellihab includes a knee brace that emits the pulses and a smartphone app patients use to track and manage the therapy.

The FDA’s two-day advisory hearing yielded recommendations for risk designation for a number of product types, such as plunger-like joint manipulators, which received a unanimous endorsement for a class III designation. The advisory panel was split on the risks associated with electro-acupuncture stimulators, which the FDA must now decide whether to classify as a class III device, a move that would force a number of existing devices into clinical trials for an expensive and time-consuming PMA application.

Synchron Inc. landed $40 million in new funding through a series B fundraising round led by Khosla Ventures. This round brings the total amount raised by the company to $59 million since its founding in 2016. Other participants in the round included Forepont Capital Partners, ID8 Investments, Shanda Group, General Advance, Subversive Capital, and Re.mind Capital as well as Arani Bose and Thomas Reardon. Returning investors included Neurotechnology Investors, Metis Innovative, and the University of Melbourne.

Early feasibility studies for cardiology devices were a massive problem for the FDA and industry in times gone by, a problem that was believed to drive device flight from the U.S. That problem has been largely solved, according to the FDA’s Andrew Farb, but Farb noted that neurological devices are the next target for improved early feasibility study (EFS) development in the U.S., which suggests that the path to pivotal studies for devices in this space will soon be much less cumbersome.
