🏆 DCB Open Innovation Challenge 2025: Incredible 54 ideas were submitted to the DCB Open Innovation Challenge this year. Five finalists from various countries pitched their innovations live on stage at sitem-insel in front of a big audience and an international jury. This year’s winner, the U.S.-based start-up Alva Innovations, convinced the jury with its pioneering real-time filtration system for insulin pumps, designed to prevent infusion-set occlusions and improve therapy safety for people living with diabetes.

Their technology has the potential to significantly enhance the reliability of insulin delivery systems and reduce treatment disruptions addressing one of the most frequent challenges in insulin pump therapy today. For the first time, the DCB expanded the traditional Start-Up Night into a full Day of Innovation, held on 5 November 2025 at the sitem-insel in Bern. The event brought together leaders from healthcare, academia, medtech, industry, and policy to explore future-driven solutions in medicine and health technology.

The programme of the Day of Innovation featured:

• Start-up pitches from the Top 5 finalists (Alva Innovations, Neuraura, SynchNeuro, Diawiser, MEMS MicroPump Module)
• Keynotes and insights from research, translational medicine, and industry translational research at DCB, sitem-insel, CSEM)
• Showcases demonstrating real-world impact and successful commercialization (T1D1, SNAQ, Piomic, MYNERVA, GO-Pen, Alveolix)
• Perspectives from policy (Christoph Ammann) and medical ethics (Prof. Giovanni Maio) on advancing innovation and artificial intelligence in healthcare
• Networking sessions connecting innovators, investors, clinicians, and partners

About the winner: Alva Innovations

➡️ Looking ahead: DCB will continue to support the finalist teams beyond the Challenge with access to expert guidance, clinical expertise, and strategic support.

🚀 Tailored Workshops for start-ups: Multiple workshops were organized for various start-ups, covering different key topics. They ranged from a few hours virtually to multiple days in person. The workshops addressed everything from clinical insights, data management, project management, communication, to branding. A key point noticed was that investor decks were often too detailed and overloaded with content. Top tip: Investors typically spend only 2.5 to 3 minutes reading them!

📊 DT-report: Together with diabetesschweiz, the Swiss Society for Endocrinology and Diabetology (SGED | SSED), and partners in Germany and Austria, we are conducting a representative survey on the topic of diabetes technology for the 2026 Diabetes Technology-Report. The project team managed to onboard additional countries: Poland, Italy, Spain and Slovenia. This makes this report even more relevant, as more voices of people with diabetes are being heard, allowing research, industry, and policymakers to work together toward even better care.

🎉 DCB spin-off Beyond Diagnostics receives Innosuisse grant: Dr. Maren Schinz has secured an innovation grant from Innosuisse to advance her research on insulin inactivity with Beyond Diagnostics, a DCB spin-off. Congratulations!

Clinical & Data

🩸 Menstrual cycle project: We are about to publish the results of the menstrual cycle project which was conducted in close collaboration with Tidepool. The aim of this research project was to collect data on diabetes management among menstruating people living with type 1 diabetes to evaluate changes in insulin sensitivity across the menstrual cycle. We have received data from 380 cycles of 77 women and look forward to presenting the first results soon. This retrospective study was the first study at the intersection of type 1 diabetes and women’s health.

💜Focus groups women and AID: We conducted a qualitative study involving interviews with 37 women living with type 1 diabetes and using an AID to manager their diabetes to explore their experiences managing diabetes in relation to the menstrual cycle. Participants were asked about the challenges they encountered and the strategies they used to address cycle-related changes in insulin requirements. All interviews were audio-recorded, transcribed, and systematically analyzed to identify the primary management strategies and overarching themes shared across participants.

📊TIMES study: We successfully secured funding for an international decentralized study about the influence of the menstrual cycle on type 1 diabetes management. In total 350 women across five countries (Switzerland, Germany, Denmark, UK and US) will participate in the study for six months. The first study participants have been recruited in Switzerland. This study is a follow-up of two other previous studies on the same topic.

🔎Clinical Study FibreGum: Under the supervision of our assistant professor Maria Luisa Balmer, the FibreGum study, conducted at the Children Clinic Berne and the Eastern Swiss Children’s Hospital in St. Gallen, is assessing the effect of an additive in a chewing gum on body weight loss. So far,93 adolescents and young adults have been enrolled. An interim analysis will be performed at the end of this year to evaluate data integrity, variability, and preliminary effect sizes.

🔎Clinical Study FaibaGo: Under the supervision of our assistant professor Maria Luisa Balmer this clinical study is testing a fibre-rich chewing gum that aims to support people with overweight in achieving sustainable weight loss and improved metabolic health. It is the counterpart to the FibreGum study conducted in adult population. More than 30 general practitioners (GP) in the Bern area are already involved, helping to recruit suitable participants despite their busy schedules. The study began mid-October and, within two months 15 participants, out of a planned total of 120, have already been enrolled.

🔎Clinical Study AID-JUNCT: Under the supervision of our assistant professor José Garcia Tirado, the AID-JUNCT is evaluating the efficacy of tirzepatide (Mounjaro®) as adjunctive therapy to automated insulin delivery on percent time in range. It has been running for one year at the Cantonal Hospital in Olten. Two additional study sites, Cantonal Hospital in Lucerne and DiaCenTRE Geneva, were added this year. 16 participants, out of a planned total of 42, have been enrolled.

🔎 Clinical Study UBLoop regulatory approval obtained: Assistant professor José Garcia Tirado will conduct the UBLoop study at the facilities of the DCB. This is a first in human study, testing the feasibility of a new closed loop system in six participants.

✅ Evo Study conduct completed (Study Sponsor: BODYSense SAS): The study does examine associations between glycaemic states such as stable, increasing, and decreasing blood glucose, and the VOC (volatile organic compound) spectra in the breath measured with a Gas Chromatograph-Ion Mobility Spectrometer (GC-IMS) device as a reference and a portable device prototype to measure VOCs. The device prototype has been developed by BODYSense with the purpose to allow blood glucose monitoring through non-invasive breath analyses. The study has been completed and we are now waiting for the results to be published.

👥 Study conduct network extension: The Eastern Swiss children’s hospital in St. Gallen, the Cantonal Hospital in Olten and the Division of Endocrinology and Diabetology of the Medical University of Graz (Austria) are now qualified as study sites and are allowed to conduct studies under our support/responsibility.

📖 Contribution to publications: The publication led by Prof. Lilian Witthauer titled “Toward Detection of Nocturnal Hypoglycemia in People with Diabetes Using Consumer-Grade Smartwatches and a Machine Learning Approach” was featured in the Journal of Diabetes Science and Technology.

A preprint authored by Liom titled “A Prospective Pilot Study Demonstrating Non-Invasive Calibration-Free Glucose Measurement” was published on medRxiv.

DCB also featured numerous abstracts presented at major diabetes conferences, including ADA, EASD and ATTD.

📊 Electronic Data Capture System: REDCap® has undergone significant upgrades and enhancements through the integration of external modules and services. These improvements ensure the platform continues to provide a secure environment, uphold strict quality control standards, and offer user-friendly interfaces.  The e-consent module, which allows to obtain informed consent electronically, has been implemented earlier this year and is currently being used in several decentralized clinical trials.

🔬 INSPIRE LAB

Within the INSPIRE Lab we explore how real-world conditions impact the biological activity of insulin – its ability to lower blood glucose levels – providing insights onto this hidden factor in diabetes management.

Currently, most methods measure how much insulin is present, but not whether it is still active.

Our DCB spin-off Beyond Diagnostics addresses this critical diabetes care gap by developing an AI-powered point-of-care test that verifies insulin medication quality. In addition to the financial support by Innosuisse, we won STAGE UP, were a Newcomer at the startup days, and published our first paper in the Journal of Diabetes Science and Technology “Real-World Experience with Insulin Activity among People with Type 1 Diabetes: Results of a Multinational Survey”.

And, as exciting lookout, we will officially be founded in 2026!

Research at the Diabetes Centre Berne: Focus on the menstrual cycle and insulin requirements

The Diabetes Centre Berne (DCB) is investigating the influence of hormonal fluctuations, particularly the menstrual cycle, on diabetes management. Martina Rothenbühler and Stefanie Hossmann explain how they are working with the community to collect data and gain new insights to help those affected.

Martina Rothenbühler (MR) and Stefanie Hossmann (SH), what are your roles at the Diabetes Centre Berne (DCB)?

MR: My focus is on data analysis and developing research questions. I draw on my background in biostatistics and investigate, for example, how hormonal fluctuations influence insulin requirements.

SH: I am responsible for coordinating studies at the DCB and ensuring compliance with regulatory requirements. My background as a biologist enables me to tailor these studies to the specific needs of the participants.

How did you come up with the idea to research this topic?

SH: We learned from the diabetes community, from various people living with diabetes, that there are fluctuations in diabetes management in relation to the menstrual cycle. We then began to look into the topic in more detail. We found very little on this in the mainstream scientific journals, so we decided to investigate the topic more thoroughly. There are different phases in the menstrual cycle during which hormones increase or decrease. These include, for example, the follicular phase and, at the end, the luteal phase. Ovulation takes place in between. Since all of this is closely linked to hormones, we assumed that insulin requirements are also affected.

MR: I previously worked at Ava, a femtech start-up. There, we conducted research projects that showed that the menstrual cycle has many different effects, for example in the areas of sport and osteoporosis. This sparked my interest, as insulin sensitivity may also be related to this.

Why has this topic been largely unexplored until now?

MR: One of the reasons is the so-called gender health data gap, i.e. the lack of health data on women. For a long time, women were excluded from clinical studies to avoid risks, for example in the event of pregnancy. In addition, hormonal fluctuations were considered potential confounding factors that could make general statements difficult. These aspects are not yet sufficiently anchored in research.

SH: That’s really surprising. With almost every new research topic, you realise that this is not a given.

How does the diabetes community view your efforts to investigate the link between diabetes and the menstrual cycle?

MR: We have mainly received feedback from people who already considered the topic important or saw it as a personal problem. However, we do not know how many women did not feel affected by it. For some, enthusiasm for our research was greater than their willingness to actually participate in the study. Nevertheless, many found the topic interesting and important, even if participating in a study is a hurdle.

SH: We also often received feedback that this issue is seen as a relatively minor problem and that more important issues should be addressed first. However, we take a different view. Especially when diabetes management is already at a high level, a small improvement, such as five per cent more time in the target range (time in range), can bring about a noticeable improvement. This has also been confirmed by the community.

What further goals are you pursuing with your research in this area?

MR: Our aim is to bring more data from women and non-binary people into medical research and to raise awareness of these issues. The focus is not only on time-in-range, but also on how technology should be designed in this context. For example, more is already known about the influence of gender on sport and nutrition in relation to diabetes.

SH: However, less research has been done on hormonal transition phases such as pregnancy, breastfeeding or gender reassignment.

MR: Or even the entire puberty phase. All these gender-specific phases are related to diabetes, but they are still largely unexplored. We are currently working on an editorial that highlights precisely these areas.

Why is this topic particularly relevant to the Diabetes Centre Berne?

MR: What is special about diabetes and the menstrual cycle is that there is no specific industry behind it and therefore hardly any commercial interests at stake. Our research covers the entire field of diabetes technology and is not limited to a single manufacturer. However, this also means that there is often little research funding available and we are dependent on third-party funding. As a foundation, we are therefore in a good position to conduct this research together with people with diabetes.

What specific projects are you currently working on, and what are your main goals?

MR: What I find exciting is the fact that, although there are restrictions for certain groups, many of those affected have nevertheless found their own solutions to deal with the challenges. They have developed strategies that work for them personally.

SH: We are currently working closely with the community to understand exactly where the problems lie and what needs exist. We are collecting data on the extent of the burden and the strategies that those affected have developed to cope with it. So far, we have evaluated data from the past. In the future, we would like to collect data in a targeted and forward-looking manner to get even better answers to our questions.

Thanks so much for reading, and we’ll provide you with the next episode of this series soon!
