Developers of tests for the SARS-CoV-2 virus have gained a tremendous amount of experience in a very small amount of time, and of all the media for sampling, saliva offers the easiest route for test administration. The U.S. FDA’s Tim Stenzel said on the Aug. 5 testing town hall, however, that the FDA and developers have discovered that this is an extremely difficult medium to work with.

The matter of how adhesion of its Viaskin Peanut allergy patch relates to efficacy became a major problem for DBV Technologies SA, which drew a complete response letter (CRL) for the once-daily epicutaneous (EPIT) product. Shares of the Montrouge, France-based firm (NASDAQ:DBVT) closed Aug. 4 at $2.34, down $1.76, or 43%, in reaction to the CRL for the patch, designed to protect children ages 4 to 11. The FDA wants DBV to modify the patch, which means a new human-factor study; officials also are requiring clinical data for the modified patch.

A number of entities have sounded off on the FDA’s discussion paper for artificial intelligence (AI), including several medical societies that would like to see autonomously operating algorithms subjected to more stringent review than supervised algorithms. Vibhor Rastogi, general partner at Symphony AI of Los Altos, Calif., told BioWorld that the company is on board with many of these concerns, adding that the FDA discussion paper does a “good job of balancing innovation and patient safety.”

Medtronic plc has won U.S. FDA approval of its Interstim Micro rechargeable sacral nerve stimulator and Interstim Surescan MRI leads for the treatment of urinary and bowel dysfunctions. The new products make Medtronic the only company to offer a choice between rechargeable and recharge-free sacral neuromodulation (SNM) systems, allowing patients to align their treatment with personal lifestyle preferences.

The U.S. FDA expanded the indications for Stryker Corp.’s Neuroform Atlas stent system to include use in the posterior circulation or back of the brain, making the device the only adjunctive stent approved for aneurysms in this challenging location. The Kalamazoo, Mich.-based company’s intracranial coil-assist stent gained its initial indication for the more common aneurysms in the anterior circulation of the neurovasculature in May 2019.

LONDON – Morphosys AG finally has some heft to put behind its U.S. commercialization ambitions following FDA approval for its long-nurtured anti-CD19 antibody, Monjuvi (tafasitamab-cxix) in relapsed or refractory diffuse large B-cell lymphoma (r/rDLBCL).

In a time when the FDA needs its best and brightest people onboard, nearly half the senior leadership at the agency will be eligible for retirement by Sept. 30.

The U.S. FDA has nudged the emergency use authorization (EUA) program forward once again, this time with a template for applications for tests that can be performed entirely at home, in the office and at schools. FDA Commissioner Stephen Hahn said in an accompanying statement that tests of this sort “will be a game-changer in our fight against COVID-19 and will be crucial as the nation looks toward reopening.”

PARIS – Therapixel SA, of Nice, France, has obtained 510(k) clearance from the U.S. FDA for its Mammoscreen technology, a software platform based on artificial intelligence (AI) and used by radiologists for reading screening mammograms. “Obtaining FDA clearance is the result of working with radiologists over the past three years in order to develop a powerful tool providing relevant assistance in their day-to-day work,” Matthieu Leclerc-Chalvet, CEO of Therapixel, told BioWorld.

The U.S. FDA has rewritten the emergency use authorization (EUA) for the Laboratory Corp. of America Holdings Inc. (Labcorp) COVID-19 polymerase chain reaction (PCR) test to allow for diagnostic testing of those who are asymptomatic and those who have no reason to suspect they are infected with the SARS-CoV-2 virus.
