Gent, Belgium: Nov 27, 2018 – Fujirebio Europe today announced the availability of the Lumipulse G pTau 181 and β-Amyloid 1-40 assays for its fully automated LUMIPULSE G immunoassay systems. These CLEIA (chemiluminescent enzyme immunoassay) reagents allow for the quantitative determination of Tau phosphorylated at threonine 181 and β-Amyloid1-40 protein, respectively, in human cerebrospinal fluid (CSF) within just 35 minutes.
The launch of these two new parameters on Fujirebio’s automated LUMIPULSE G systems marks the availability of four parameters within this fully automated neurodegeneration product line. The Lumipulse G pTau 181 and β-Amyloid 1-40 assays complement the Lumipulse G β-Amyloid 1-42 and Total Tau assays launched last year to a full CSF core biomarker panel. Together, these four CSF biomarkers support the diagnosis of Alzheimer’s disease, with the β-Amyloid1-42/β-Amyloid1-40 ratio reflecting the amyloid load in the brain and allowing for a reduction of the effect of inappropriate pre-analytics.
Both new Lumipulse G assays are a logical next step as a fully automated alternative to Fujirebio’s well established, pioneering INNOTEST® ELISAs, the first ever commercial neurodegeneration IVD testing range and used by laboratories worldwide. Fujirebio has a long company history of developing automated CLEIA tests dating back to the first, pioneering generation of LUMIPULSE analyzers in 1992.
About Alzheimer’s disease
Alzheimer’s disease (AD) is a widespread condition that occurs in 50% to 60% of individuals suffering from dementia. Globally, it is one of the most disabling and burdensome of health conditions and its incidence is rising rapidly due to increasing life expectancy. From the age of 65 the incidence of AD doubles every five years (from around 2-3% to no less than 35-40% after 85 years of age). This public health care issue translates into 46.8 million of people suffering from the condition worldwide today. The number is set to reach 74.7 million in 2030, surging to 131.5 million in 2050.1
The challenge of early, accurate diagnosis
Alzheimer’s disease starts silently and develops several years before clinical symptoms appear. Until recently, it has been difficult for physicians to predict which individuals with memory problems will eventually develop AD, and which ones will not. Even when clinical symptoms of dementia are present, the clinical diagnosis of AD is reported to be correct in only 65% to 96% of the time.2 Accuracy rates tend to be especially low in the earlier stages of AD. New diagnostic tools to help detect AD as early as possible with the highest level of certainty are of fundamental importance for both physicians and the patients and families involved. This is because memory complaints can result from several causes and may be reversible. In its early stages, it is especially difficult to discriminate AD from any other type of dementia, depression, or even normal aging.
Another reason that early detection tools are urgently needed is because it is believed that the treatment of diseases such as AD ideally should begin as soon as possible. Pharmaceutical companies trying to develop new AD treatments need reliable tests to establish clear-cut treatment groups and means of monitoring the effectiveness of candidate treatments.3
