mAbXmise determines the plasma concentration of monoclonal antibodies prescribed as single or combination therapies at selected time points. Its unique technology is based on mass spectrometry and allows multiplex measurement (several mAbs at once) with high analytical performances. The kit is designed to be easy-to-use and allows optimal reliability and accuracy using LC/MS technology. Healthcare professionals can then use the information to personalize treatment and manage patient care[1]
Therapeutic drug monitoring consists of measuring the plasma concentration of a drug, so as to adjust the dosing and maintain its target plasma concentration.
Since the 2000s, monitoring of therapeutic antibodies has begun to emerge in the management of inflammatory diseases and oncology, with immunological methods.
mAbXmise uses a different approach. It lies on mass spectrometry, a particularly sensitive and above all extremely specific technology. The technology allows the therapeutic antibody in the sample to be measured very accurately.
We believe the onset of mAbXmise technology will dramatically change the way biologics are monitored in the future.
Current treatment regimens are still either single-dose or calculated on the basis of patient weight, whereas there is increasing evidence of inter-patient variability due to several factors such as age, gender, pathological state and others.
With mAbXmise, we hope we can facilitate the adoption of this practice in the hospital, to allow individualized medicine by personalizing the frequency of administration, compensate for inter-individual variability and reducing treatment costs.[1]

Promise Proteomics was created in 2010 as a spin-off of CEA Grenoble (France). This medtech company is currently wholly owned by the Aguettant group and is directed by Dr Eric Rougemond.
Since 2013, Chief Scientific Officer of Promise, Dorothee Lebert, has led ambitious and collaborative R&D programs which have allowed to develop the technology, on which the diagnostic kits for personalized medical applications are based.
Capitalizing on its unique know-how in the production of internal standards for protein assays and its recognized expertise in mass spectrometry-based quantification methods, Promise Proteomics is placing its skills at the service of healthcare professionals through its mAbXmise kits.
Innovation, Development, Industrialization, Production capacities, Market Acess & Regulatory affairs, Quality are the expertises gathered by the company.
