Product News: Thermo Fisher Scientific launches EXENT Solution with IVDR Certification

Transforming monoclonal gammopathy management to address an unmet clinical need through an innovative mass spectrometry solution

09 Apr 2024

Thermo Fisher Scientific has launched the EXENT® Solution, after receiving IVDR certification*. The EXENT solution is a fully integrated and automated mass spectrometry system designed to transform diagnosis and assessment for patients with monoclonal gammopathies, including multiple myeloma. It is now commercially available in Belgium, France, Germany, Italy, the Netherlands, Spain and the UK.

The EXENT Solution enables clinical laboratories to measure, quantify and track specific endogenous M-proteins and exogenous therapeutic monoclonal antibodies with enhanced analytical sensitivity and specificity in serum. It is easy to implement in routine laboratory use and features three integrated modules: EXENT-iP®500, an automated sample preparation instrument; EXENT-iX®500, a Matrix Assisted Laser Desorption Ionization – Time of Flight Mass Spectrometer (MALDI-ToF MS); and EXENT-iQ®, an intelligent and intuitive workflow software, including data review. The analyser is combined with the EXENT® Immunoglobulin Isotypes (GAM) immunoassay, a highly sensitive and specific immunoassay for measuring and quantifying IgG, IgA, and IgM.**

Traditionally, treatment for monoclonal gammopathies is determined by monitoring M-protein levels, which can indicate tumor size. With remarkable treatment successes in recent years, many patients are achieving M-protein concentrations below detectable limits using standard techniques. However, differences in disease progression persist within this group. The EXENT Solution addresses this unmet clinical need for more sensitive analytical methods that can differentiate between subsets, without initiating invasive bone marrow biopsy techniques too early.

The EXENT Solution was developed with Mayo Clinic intellectual property, combining industry leadership in innovation with Mayo’s expertise in monoclonal gammopathy research. It is intended to aid diagnosis of monoclonal gammopathies and monitoring of multiple myeloma and Waldenström’s macroglobulinemia patients.

Thermo Fisher Scientific completed the acquisition of The Binding Site early in 2024, adding protein diagnostics solutions, including diagnosis and monitoring for monoclonal gammopathies, to its specialty diagnostics portfolio.

The EXENT Solution is not commercially available in the USA or China, future commercial availability cannot be guaranteed. Product availability is subject to country specific regulatory requirements.

*The EXENT Solution consists of the following CE marked products: EXENT Analyser, IE800 (IVDR Class A, nonsterile), Immunoglobulin isotypes (GAM) for the EXENT Analyser  MSR801.M (IVDR Class C), EXENT Immunoglobulin Isotypes (GAM) Control Pack - MSQ801.M (IVDR Class C).
