Neurocode USA Inc. added Alzpath Dx, a blood test for Alzheimer’s disease screening, to its lab developed tests, making it the first available for commercial use in the U.S. The move stands to make screening for the neurodegenerative disease much more accessible, as recent study results indicate Alzpath’s accuracy rivals PET scans and cerebrospinal fluid tests, the current gold standards, in detecting the signature biomarkers of the disease.
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.
The news from Quanterix Corp. has come fast and furiously this week. The company reported that Chairman and CEO Kevin Hrusovsky will step down on April 25 and become executive chairman of the board, while current company President Masoud Toloue will assume the CEO position and join the board of directors. Hrusovsky became CEO in 2014 and Toloue joined Quanterix in June 2021 from Perkinelmer Inc. The company also revealed that it has built on its collaboration with Indianapolis-based Eli Lilly and Co. for new tools to diagnose, monitor and treat Alzheimer’s disease (AD) and presented its fiscal 2021 financial results, which showed a 28% increase in total revenue, largely attributable to its neurology segment.
The U.S. FDA has granted emergency use authorization (EUA) to Quanterix Corp.’s SARS-CoV-2 IgG antibody test, which tests blood samples for evidence of recent or prior COVID-19 infection. The test could also be used to measure antibody response to a COVID-19 vaccine. The Simoa Semi-Quantitative SARS-CoV-2 IgG antibody test is indicated for the qualitative and semi-quantitative detection of IgG antibodies to SARS-CoV-2 in human serum and dipotassium EDTA plasma from a venous blood draw.
Quanterix Corp., of Billerica, Mass., reported that researchers have developed a COVID-19 antibody test with 1,000 times the sensitivity of current tests using its Simoa bead-based immunoassay platform.
