Sampling of dermal Interstitial Fluid (dISF)

Pioneering Hollow Microneedles

Ascilion designs, develops, and manufactures products based on hollow microneedles for sampling of dermal interstitial fluid (dISF).
Access to endogenous and exogeneous biomolecules in dISF represents a unique opportunity for analysis of vital markers, health conditions and for research.
Bringing biomolecules out of the body and into analysis is paramount for the next step in life science.

Background

Founded on the premise of radically improving healthcare, the team set out to develop hollow microneedles that can sample dermal interstitial fluid in a pain-free and easy to use way. After almost 10 years of development, the company is entering into numerous clinical trials with the aim of characterizing both the system and dISF itself.

Ascilion announces enrollment of first patient in DIGIPREDICT-Bio-DE study

STOCKHOLM, SWEDEN – Ascilion AB ("Ascilion") the leader in dermal interstitial fluid sampling for biomarker investigation announced today that the first patient has been enrolled in the DIGIPREDICT-Bio-DE study at the Deutsches Herzzentrum der Charité ("DHZC") in Berlin, Germany.

Ascilion´s microneedle technology is used to extract dermal interstitial fluid (dISF), the fluid between cells in the skin. This fluid is rich in biomarkers, some of which are unique, and is a previously untapped source of health information.

Part of the pan-European DIGIPREDICT program, the study utilizes Ascilion´s technology to sample dISF, that is then used to validate a sensor platform developed to detect biomarkers relevant to cytokine storms and cardiovascular disease.

Last week the first ambulatory heart-failure patient was enrolled in the study at DHZC. The subject performed a cardiopulmonary exercise test (CPET) and both blood and dISF were sampled. By comparing biomarker concentrations in dISF and blood, biomarker sensors can be validated, and biomarker dynamics in dISF evaluated.

Dr Laurenz Kopp Fernandes, Senior Physician at DHZC, commented: “The ability to sample dermal interstitial fluid means we now have really minimally-invasive access to established as well as to probably new biomarkers, which will potentially change the management of our patients. We are only now learning about how valuable the biomarker information contained in dISF can be. The enrollment of the first patient is an important step towards their investigation, and I am looking forward to the new insights we will gather in this important study.”

Simon Grant, CEO of Ascilion commented: ‘This project illustrates the potential for dISF sampling to take a central role within patient monitoring and management. Today, Ascilion has established relationships with global leaders in several industry segments. At the same time we have seen an increase in interest over the last 18 months that has been remarkable as researchers and industry learn about dISF and our technology.’

This project has received funding from the European Union’s Horizon 2020research and innovation programme under grant agreement No 101017915(DIGIPREDICT). www.digipredict.eu

About Ascilion
Ascilion is the world leader in sampling of dermal interstitial fluid (dISF). A pioneer within hollow microneedle technology, Ascilion has developed the only solution available for sampling of practical amounts of pure dISF, enabling complete quantitative biomarker evaluation. Ascilion’s product PELSA is painless, quick, easy to use and leaves no residual mark on the skin. PELSA is available for research use and for pharmaceutical or cosmetic testing applications and is currently undergoing the medical product approval process. We are a cross-functional team based just outside Stockholm, Sweden and currently work with selected industrial partners and researchers.  

About DIGIPREDICT

DIGIPREDICT – Digital Edge AI-deployed DIGItal Twins for PREDICTing disease progression and need for early intervention in infectious and cardiovascular diseases beyond COVID-19.

DIGIPREDICT is a pan-European research program bringing together scientific and technical excellence in multiple disciplines including informatics, engineering (embedded systems,sensors and wearables), medical science, translational science, ethical and regulatory frameworks. The consortium consists of in total nine members from academia, two large R&D institutes, two hospitals, three high-tech SMEs from five European countries. The project will develop Digital Twins to enable identification, monitoring, and screening of high-risk patients, and to provide them with the right supportive therapy based on referral decisions that can be personalized. A digital twin is a digital representation of an object or process from the real world in the digital world – and more specifically for the case of DIGIPREDICT – of a patient.

DIGIPREDICT will also develop wearables for early detection of infectious and cardiovascular diseases.

Ascilion technology judged top 1% of EU funded Innovations

STOCKHOLM, SWEDEN – Ascilion AB ("Ascilion") the leader in dermal interstitial fluid sampling, announced today that Ascilion’s technology received the highest possible rating for both Market Creation Potential and Market Readiness from the European Commission’s Innovation Radar group.

Ascilion´s microneedle technology is used to extract dermal interstitial fluid, the fluid between cells in the skin. This fluid is rich in biomarkers, some of which are unique, and is a previously untapped source of health information. Today, Ascilion works with global leaders in several industry segments to access and utilize this information.

As an essential part of the EU-funded pan-European DIGIPREDICT program, Ascilion has provided the sampling technology for the project. The Innovation project is titled ‘Minimal invasive system for dermal interstitial fluid (dISF) sampling and collection’.

Of the nearly 12,000 projects evaluated to date by the EU Innovation group, only 152 have received this highest level of evaluation, placing Ascilion in the top 1% of projects funded by EU. The evaluation is made up of two parts: Market creation potential and Market maturity.

Market creation potential was judged to be ’Very High’, the highest grade, and is an indication of the potential commercial impact the technology and products can have on the market. Market maturity was judged as ‘Market Ready’ which indicates that the products are ready to market, now.

Simon Grant, CEO of Ascilion commented: ‘We are extremely pleased that the EU has understood the potential and implications of our technology, and also how far the team has come with the products. To receive the highest rating in one classification is an achievement, to receive it in both is very rare. We believe that the potential for our products is broad and that they can open entirely new and exciting possibilities within monitoring and diagnostics that create significant value for industry while helping patients and consumers.’  

The project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No101017915 (DIGIPREDICT). www.digipredict.eu
