Quanterix Corp.’s Simoa technology helped drive a large, international study to establish reference ranges of serum neurofilament light chain (sNfL) to assess individual disease activity and drug response in multiple sclerosis (MS) patients. The study, published in The Lancet Neurology, utilized Simoa’s ability to precisely detect sNfL protein at ultra-low levels, enabling it to be reliably measured across a broad range of healthy individuals.

C2i Genomics Inc. reported the formal launch of its C2inform minimal residual disease diagnostic across Europe, after obtaining CE marking for the cancer test. The Cambridge, Mass.-based company also has completed several clinical trials it ran with research partners to validate the technology and will be presenting data in different cancers at the American Association for Cancer Research in New Orleans, April 8-13.

As was the case with left atrial appendage closure, renal denervation (RD) as a treatment for hypertension has proven to be difficult to move along into routine clinical usage. New data for a study sponsored by Medtronic plc showed that RD offers a statistically significant improvement over sham treatment in reducing hypertension, but the data do not seem to suggest that patients will be able to drop their antihypertensive medications after RD treatment.

The tricuspid valve at times seems the lost child of the heart’s valves, but new research hints that regurgitation of this valve can be resolved with a transcatheter replacement. Adam Greenbaum, of Emory University School of Medicine, said the early feasibility study of the Pascal valve by Edwards Lifesciences Inc., of Irvine, Calif., demonstrated a large improvement in mortality at one year and significant improvements in heart failure status, a result that offers new hope for these patients.

A 2,000-patient U.K. study has been set up to generate real-world evidence of the value of using AI technology to detect bowel polyps (adenomas) during colonoscopy procedures. The aim is to show whether Medtronic plc’s GI Genius system improves the detection of polyps when deployed in both expert centers and non-specialist units, in the routine diagnostic screening of patients referred from primary care or through the national fecal immunochemical testing program.

There has been some skepticism about the value of electronic health records (EHRs) beyond their role as a source of income for EHR developers, but an April 3 presentation at the 2022 America College of Cardiology scientific sessions being held in Washington suggests this type of software offers some real value for heart failure patients. Tariq Ahmad of Yale School of Medicine said a study of EHRs suggests their power lay in part in prompting compliance with heart failure medication regimes, an application of this type of software that can both save lives and cut costs for the Medicare program and Medicare beneficiaries.

Pharmaceutical agents took center stage in Washington on the first full day of the 2022 scientific sessions of the American College of Cardiology, such as an April 2 presentation on the use of the mavacamten for obstructive hypertrophic cardiomyopathy (OHC). Milind Desai of the Cleveland Clinic said 16-week data for this cardiac myosin inhibitor showed well in reducing heart failure class status, but there are data arising from studies in China which suggest that radiofrequency (RF) ablation might also work for these patients.

Carthera SA reported results from a pilot clinical trial to evaluate the safety and efficacy of its Sonocloud technology in patients with mild Alzheimer’s disease (AD). The results, published in Alzheimer’s Research and Therapy, show early promise of the treatment in reducing the amyloid load of AD and potentially other neurological conditions as well as to stimulate neurogenesis and improve cognitive performance.

With the Russian invasion of Ukraine continuing to disrupt thousands of clinical trials throughout the region, the European Commission, the EMA and the Heads of Medicines Agencies are developing advice to help sponsors mitigate the issues. For now, sponsors should apply the approaches and flexibilities used during the COVID-19 pandemic to the current situation, the groups said March 30.
